Project File Number: Applicant: Type of Permit Applied for: Project Description: Location: Associated Files: Comprehensive Plan Designation/Zoning District: I. PROJECT INFORMATION L18-0030 Elias Gardner, SRG Partnership, Inc. Shoreline Tree Removal and Vegetation Clearing Proposal is to remove and replace 13 trees within the shoreline jurisdiction on the proposed B-52 Memorial Park site. King County Parcel # 5729800010 L18-0031 Shoreline Substantial Development Manufacturing Industrial Center/Heavy Industrial (MIC/H) II. DECISION SEPA Determination: An Environmental Checklist was submitted for the B-52 Memorial Park proposal (E16- 0001) and a Notice of Decision was issued approving the proposal as a Planned Action on March 10, 2016. Decision on Substantive Permit: The Community Development Director has determined that the special permission application does comply with applicable City and State code requirements and has approved that application, subject to the following conditions: 1 1. Applicant shall plant at least 23 of the required 80 replacement trees on -site per approved plans. Payment into the City's Tree Fund is allowed for up to 57 replacement trees. At the time of this writing, the fee per replacement tree is $124.00; this fee is subject to change. At the time of initial planting inspection associated with the building permit, payment into the City's Tree Fund will be at the rate codified/in place at the time of inspection. 2. Trees may be planted between October 15th and April 15th; this ensures the best start for tree health and retention for the mitigation monitoring period and beyond. Trees shall be planted after construction of the B-5 Park, as construction equipment has the potential to damage newly planted trees. 3. Trees should be watered weekly during the dry months (generally July -September or as necessary depending on conditions) for the first two growing seasons or until the plants are established. 4. Applicant shall submit annual photos of all 23 replacement trees to the City's Urban Environmentalist (Andrea.cummins@tukwilawa.gov) to ensure proper maintenance and a 100% survival rate for three years following the initial landscape inspection. 5. Per TMC 18.44.080.6.5, the property owner is required to ensure the viability and long-term health of trees planted for replacement through proper care and maintenance for the life of the project. Replaced trees that do not survive must be replanted in the next appropriate season for planting. 6. Topping of trees is prohibited (unless absolutely necessary to protect utility lines) and will be regulated as removal requiring tree replacement. 7. Contact the City's Urban Environmentalist (Andrea.cummins@tukwilawa.gov) for a post -construction inspection of protected trees. All corrective or reparative pruning must be conducted by a Qualified Tree Professional. III. FINDINGS This tree clearing permit application is to remove 13 trees within the shoreline jurisdiction along the southern border of the proposed B-52 Bomber Memorial Park site. The subject trees include 11 Lombardi poplars and two native Bitter cherries, ranging from 25 feet to 85 feet in height and 8 to 26 inches in diameter at 4.5 feet from the ground. Three trees were previously topped at 35 feet, and two trees are diseased and considered not viable. Per TMC 18.44.080.B, 80 replacement trees are required, which was determined based on the number and size of trees removed. The applicant is proposing planting 23 of the required replacement trees on site. Several options were considered to increase the number of replacement trees planted on site, including adding trees to the eastern portion of the site, screening the trailers on the south side of the property, or adding trees in large planters that could be moved, if needed. Per the applicant, these options conflicted with project goals of maintaining visibility of the military branch flags, sculpture, and the aircraft, as well as operational requirements of the site. The trees to be planted on site include a native mix of Western Red Cedar, Cascara, Shore Pine, and Oregon Ash. An irrigation system is included to ensure the viability and long-term health of the replacement trees. An existing tree located close to the park on the adjacent parcel to the south will be retained and its critical root zone protected during construction. Payment into the City's Tree Fund is allowed for up to 57 replacement trees. At the time of this writing, the fee per replacement tree is $124.00; this fee is subject to change. At the time of initial planting inspection associated with the building permit, payment into the City's Tree Fund will be required at the rate codified/in place at the time of inspection. 2 IV.

Please see our responses below in red. The design team and the Museum of Flight are committed to working towards resolutions that support the City of Tukwila's shoreline development criteria, and we're happy to have your team's input on this project. Please let me know if you have any questions - I will be available tomorrow and next week (outside of the holiday) to discuss further where necessary, and to provide clarification where needed. Thanks again, ELIAS GARDNER, Assoc. AIA LEED AP D 206 973 1685 0 206 973 1700 SRG PARTNERSHIP, INC srgpartnership.com From: Lynn Miranda Sent: Tuesday, June 26, 2018 12:16 PM To: 'Stan Jaworowski' <sjaworow@srgpartnership.com> Subject: B-52 Park Project L18-0030 & L18-0031 Hi Stan, I'm working on the staff report for the Shoreline Tree Removal and the Shoreline Substantial Dev Permits and have a couple of questions and considerations: 1. Looks like the support structures for the plane are about 8' in height above grade. Do you know the maximum height of the plane when mounted? Response: Detail 3/5002 notes a maximum dimension of 4'-0" above grade to support post point of connection. Museum of Flight plans to mount the aircraft no higher than is necessary to transfer weight from the landing gear to the support posts, while also allowing tires to remain in contact with the ground to prevent them from spinning. This anticipated vertical adjustment is in the vicinity of 6 inches. Since the maximum height of aircraft is 41'-7" measured to the top of the vertical tail fin, the maximum height of the final mounted assembly is anticipated to be 42'-1" above grade. Note that the fuselage itself is significantly lower: with mounting adjustment, the maximum height of fuselage is anticipated to be 17'-11" above grade. 2. Our urban environmentalist is concerned about the limited number of replacement trees you're proposing to plant on -site and the large number to be added to the tree replacement fund. The criteria in TMC 18.44.080.6.6. state that "If all required replacement trees cannot be reasonably accommodated on the site, off -site tree replacement within the shoreline jurisdiction may be allowed at a site approved by the City. Priority 1 for off -site tree planting will be at locations within the Transition Zone. If no suitable off -site location is available, the applicant shall pay into a tree replacement fund." Response: The Owner and the design team do not believe planting additional trees on site within the shoreline jurisdiction would be in keeping with the design intents or operational requirements of the Project or of affiliated user groups, for reasons elaborated upon in responses below. Further, the Owner cannot validate a suitable off -site location within the adjacent shoreline jurisdiction, for reasons also elaborated upon in responses below. We understand the need to not plant on King County's easement on the west side of the property. However, we would like to see more trees accommodated on the project site (first priority), or offsite in the shoreline environment (2"d priority). Here are a couple of options for you to consider as you look for appropriate locations for adding more trees: • Adding trees to the east side of the property, between the walkway (around the sculpture) and the parking area. This would also provide shade for park visitors. Response: We have not included trees in the memorial area on the east side of the project site in order to maintain visibility to military branch flags and sculpture at the top of the slope. Locating trees here would also block the view of the aircraft from surrounding vantage points. It has been a primary goal to maintain visibility of the memorial to attract patrons and passersby to venture to this corner of the campus. • Adding trees in large planters along the western side of the park. Would King County accept trees in planters instead of planted in the ground? Trees in planters could also be placed around the plaza area. Response: The design team has advised against trees in planters. These have a low survival rate, and have limited mobility should the Owner or King County need to gain access to this area. • Adding trees behind the trailers on the south side of the property. Response: At the south side of the project site, the Museum of Flight has long accommodated the ongoing operations and activities of the Boeing Employees Amateur Radio Society (B.E.A.R.S.). The trailers here house sensitive communication antennae and equipment, and provide emergency communication services for Boeing and the local public service communities. Existing trees are being removed from this area in order to limit the potential for damage or interference with B.E.A.R.S. operations. • Coordinating with Boeing on planting trees in the Shoreline Jurisdiction, adjacent to Slip 6. Response: Given the known soil conditions on the project site, it is speculated that adjacent properties may likely contain contamination, unstable soils, or invasive existing plantings, suggesting that a more intrusive soils investigation, tree survey, and planting study could ensue. The Boeing parcels adjacent to the project site and to Slip 6 (King County Parcel Nos. 562420-1038 and 562420-1032) are further understood to be high -security facilities, and so we believe coordination of existing conditions investigations and tree plantings at Slip 6 to be operationally prohibitive. 3. The urban environmentalist is concerned with the number of Serviceberry trees planted, as they are prone to disease. Can some of these be replaced with another option? Response: 2 The design team acknowlk.,.5. that rust can affect Serviceberry trees, IJUL we do not advise against their planting, as rust does not usually affect the overall health of the tree. If the Urban Environmentalist requires that some or all Serviceberry trees be replaced, we would abide to supplant them with another species — please advise required quantity to replace, if necessary. Holodiscus discolor is speculated be a suitable replacement, as it is similar size to Serviceberry. I'm available to discuss comments 2&3 if you'd like. Thought I'd give you my thoughts in writing first. I'm available today until 2pm, then tomorrow from 8-4.

I understand that you will be resubmitting the landscape plans for the project so please include your responses to the following comment in your next submittal for both permits: Sheets L5.10 and L5.20 - Landscape Planting Plan (North & South) 1. There are several plants listed on the plant schedule that require wetter soil conditions than most likely exist on the site: Crataegus douglasii Malus Fusca Carex obnupta Deschampsia cespitosa Juncus tenuis Some of these plants are located appropriately in the rain garden. Those plants located outside of the rain garden must be replaced with plants that tolerate a dryer condition to ensure their survival. 2. Per TMC 18.44.080.C.1.b and g, native vegetation must be planted within the shoreline jurisdiction. The following plants are not native — please replace: Cistus salviifolius `Prostratus Salvia nemorosa `Cardonna' Allium x Millenium Sesleria autumnalis 1 3. Plant Schedule must include spacing of plants. For plants in the River Buffer, see River Buffer Vegetation Planting Densities Table in TMC 18.44.080.C.2. 4. Plant materials must be consistent with the regulations in TMC 18.52.060.A. 5. Please add the following to the Notes Section on Sheet L5.10: • Pesticides shall not be used in the Shoreline jurisdiction unless approved in writing by the City of Tukwila Urban Environmentalist. • For soil preparation in bioretention areas, existing soils must be protected from compaction. Bioretention soil media must be prepared in accordance with standard specifications of the Surface Water Design Manual. • For all other plantings (such as large planting areas where soil volumes are adequate for healthy root growth), soils must be prepared for planting in accordance with BMP T5.13, "Post Construction Soil Quality and Depth," from the Washington Department of Ecology Stormwater Management Manual for Western Washington. • Prior to planting, a soil inspection by the City of Tukwila's Urban Environmentalist must be scheduled to ensure soils are properly prepared. • Installation of landscape plants must comply with BMPs including: a. Planting holes that are the same depth as the size of the root ball and two to three times wider than the root ball. b. Root balls of potted and balled and burlapped (B&B) plants must be loosened and pruned as necessary to ensure there are no encircling roots prior to planting. All burlap and all straps or wire baskets must be removed from B&B plants prior to planting. c. The top of the root flare, where the roots and the trunk begin, should be placed at grade. The root ball shall not extend above the soil surface and the flare shall not be covered by soil or mulch. d. If using mulch around trees and shrubs, maintain at least a 6-inch mulch -free ring around the base of the tree trunks and woody stems of shrubs. If using mulch around groundcovers until they become established, mulch shall not be placed over the crowns of perennial plants. • Installation of the landscaping shall be completed and a Landscaping Declaration submitted by the owner or owner's agent at the time of the final landscape inspection. Any plant substitutions shall be noted on the Declaration. 6. Delete #3 under Notes on Sheet L5.10, as d. above replaces it. 7. Delete #4 under Notes on Sheet L5.10, as c. above replaces it. 8. Sheet L5.30. Details #3 & #4. Ensure that the specifications listed here do not conflict with the Notes on Sheet L5.10. 2 Sheet C003 1. Under General, please revise # 1 as follows: "At least one week before beginning construction, contact public works utilities inspector and Tukwila's Urban Environmentalist and schedule a preconstruction meeting." Please contact me at 206.433.7162 or Lynn.Miranda@Tukwilawa.gov if you have any questions regarding the above comments.

The tree fee will also be invoiced after the fact, generally near final permit approval. This is because the planner and urban environmentalist will need to review your landscaping plan and requested tree removal. The $2728.00 is just an estimate, depending on what trees are allowed to be removed and what monitoring may be required (this is all site specific) the cost could be more or less. The only cost due at intake is the $6828.00 The $2728.00 is an estimate that would need to be confirmed via the planner during the permitting process before payment would accepted. Expect to hear from your planner on this before final approval of your tree permit.

The project Landscape Architect,. Natalie Ross of Site Workshop, has been corresponding with Lynn Miranda regarding planting and tree replacement. A copy of an e-mail string between Natalie and Lynn is attached for your information. Approved and completed, Phase 1 removed 40,000 sf of compacted gravel paving, hazardous materials were remediated, and the site readied for Phase 2. For Phase 2, we will plant 23000 sf of native flowering meadow, install 650 sf of raingarden planting, and replace 11 non-native poplar trees and 2 diseased Bitter cherry trees with 58 native tree species, including 2 evergreen species, none of which makes up more than 20% of the total number of trees. Additionally, our new paving system is permeable. These improvements will provide better soil stabilization, improved runoff water quality, and habitat for local wildlife. The work will commence contingent upon the approval of the Building Permit, Public Works Permit, Shoreline Substantial Development Permit, and the Shoreline Tree Removal and Vegetation Clearing Permit, which we hope to receive in May. The expected completion date is November 2018. A preliminary schedule is attached for your use. The Museum of Flight is planning to exhibit a restored B-52 and create a Vietnam Veterans Memorial on this site. One of their main concerns are a row of poplars on the south edge of the site. Several existing trees are directly in conflict with the proposed B-52 wing location. Other trees close to the plane have caused concern because they represent a windfall hazard to the aircraft with the potential to damage it. Natalie and Lynn have discussed the planting and tree replacement scheme. 80 replacement trees are required; 58 can be accommodated on site. We are requesting to pay into the city's tree replacement fund for the remaining 22 trees, for an amount of $2,728 (to be confirmed by the City). We are eager to make the site a showpiece of ecological restoration and the exhibit as a new jewel in the Museum of Flight's mission of honoring the aircraft and airmen throughout the history of aviation. Please consider and approve of this approach.

We would not give any additional credit for planting larger caliper trees. One other thought is that you could explore adding some trees outside of the site in the strip of area adjacent to the river. See where I mean below. It would be on Bueirrg properly but I'm sure the Museum has a relationship with Boeing that could make this possible. ,4ai4 Lynn From: Natalie Ross <natalier,Psiteworkshop.net> Sent: Wednesday, March 7, 2018 9:19 AM To: Lynn Miranda <,_ynn.Miranda@TukwilaWA.gov> Subject: RE: Tukwila Bioretention Plant List Thanks Lynn, Another question for you; Am I right in assuming that we should be referring to the tree replacement standard for sensitive areas (wetlands, watercourses, buffers and steep slopes)? 4 3 Tree Replacement Starada '4 a.

You do need some diversity depending on how many trees you need to plant. For example, if you have to plant more than 8 trees, according to code, only 40% can be the same species, and so on.... See TMC 18.52.060.A.5. You might also want to look at 18.52.070 regarding soil prep, planting, and irrigation.

Summary: the subject trees include 11 Lombardi poplar, and two native bitter cherries. Removal is proposed for all 13 trees and will require 58 replacement trees. 1 TMC §18.06.775 Significant Tree. A "significant tree" means a tree (Cottonwood excluded) which is 4 inches or more in diameter as measured 4.5 feet above grade. 4547 South Lucile Street, Seattle, WA 98118 Tel. 206-723-0656 Clark Miller, The Museum ui Flight RE: Significant Tree Inventory and Report, 9404 East Marginal Way S March 12, 2018 Page 2 of 7 TREE EVALUATION —Tree Health, Condition and Viability I marked each tree with 1" x 3.5" aluminum tag indicating tree number. I visually inspected each tree from the ground and rated both tree health and structure. A tree's structure is distinct from its health. This inspection identifies what is visible with both. Structure is the way the tree is put together or constructed, and identifying obvious defects can be helpful in determining if a tree is predisposed to failure. Tree health assesses disease, insect infestation and old age. No invasive procedures were performed on any trees. The results of this inspection are based on what was visible at the time of the inspection. The attached inventory contains the following information and attributes for each regualted tree. Tree number as shown on tag in the field, and in the attached inventory. DBH stem diameter in inches measure 4.5 fe t from the ground. Tree Species common name. Tree Height in feet. Dripline radius in feet as the distance to the furthest extent to the tree's branches. Structure and Health rating '1' indicates good to excellent condition: no visible health -related problems or structural defects, '2' indicates fair condition; minor visible problems or defects that may require attention if the tree is retained, and '3' indicates poor condition; significant visible problems or defects and tree removal is recommended. Comments on Condition obvious structural defects, tree form, or diseases visible at time of inspection. Viability a determination by the arborist whether the tree is viable for retention. REPLACEMENT TREES Replacement tree requirements are found in TMC §18.54.130, and required replacement tree quantities are calculated based on the size of the removed regulated tree. Greenforest Registered Consulting Arborist Clark. Miller, The Museum ui Flight RE: Significant Tree Inventory and Report, 9404 East Marginal Way S March 12, 2018 Page3of7 The quantity of replacement trees required based on the removal of all the subject trees is 58. (See attachment.) Minimum sizes for replacement trees shall be 2.5-inch caliper for deciduous trees, 6 to 8 feet in height for evergreen trees. Replacement plants shall meet current American Association of Nurserymen standards for nursery stock. Planting and maintenance of required replacement vegetation shall be in accordance with best management practices for landscaping which ensure the vegetation's Tong -term health and survival. LIMITATIONS AND USE OF THIS REPORT This tree report establishes, via the most practical means available, the existing conditions of the trees on the subject property. Ratings for health and structure, as well as any recommendations are valid only through the development and construction process. This report is based solely on what is readily visible and observable, without any invasive means. There are several conditions that can affect a tree's condition that may be pre-existing and unable to be ascertained with a visual -only analysis. No attempt was made to determine the presence of hidden or concealed conditions which may contribute to the risk or failure potential of trees on the site. These conditions include root and stem (trunk) rot, internal cracks, structural defects or construction damage to roots, which may be hidden beneath the soil. Additionally, construction and post -construction circumstances can cause a relatively rapid deterioration of a tree's condition. Attachments: 1. Assumptions & Limiting Conditions 2.

The project site is shown relative to surrounding physical features on the Vicinity Map (Figure 1) and the Site Plan (Figure 2). We understand that the Museum of Flight (Museum) is currently planning to permanently display a B-52 bomber west of the covered airpark currently under construction. The site for the B-52 will be immediately south of the Aviation High School parking lot and north of Slip 6. The wheel Toads for the plane are approximately 125 kips in the back and 60 kips in the front. At this time, the project will entail constructing a foundation to support the B-52 bomber and landscaping around the display. At a later date, other landscape features might be added. Our understanding of the project is based on information provided by Nathan Messmer with SRG Architects and discussions with various team members. The purposes of this study were to review existing geotechnical information and to complete additional subsurface explorations at the project site as a basis for providing geotechnical engineering conclusions and recommendations for the design and construction of the B-52 foundation. Our services were completed in general accordance with our proposal dated December 1, 2015. Our specific scope of services for the geotechnical engineering services included: • Reviewing previous explorations completed at the site and on adjacent properties; • Completing additional borings to characterize the subsurface conditions at the site; • Performing analyses to evaluate various foundation support options; ■ Completing soil nutrient analyses; and ■ Preparing this geotechnical engineering report. FIELD EXPLORATIONS AND LABORATORY TESTING Field Explorations The subsurface conditions at the site were evaluated by completing two borings (B-1 and B-2) to depths of 31.5 and 41.5 feet. The approximate locations of these explorations are shown in Figure 2. A detailed description of the field exploration program and the logs of the borings are presented in Appendix A. Laboratory Testing Soil samples were obtained during the drilling and taken to GeoEngineers' laboratory for further evaluation. Selected samples were tested for the determination of moisture content, percent fines, gradation characteristics and Atterberg limits (plasticity characteristics). The tests were performed in general accordance with test methods of the American Society for Testing and Materials (ASTM). A description of the laboratory testing and the test results are presented in Appendix B. GEOENGINEERS� February 5, 2016 Page 1 File No. 8039.010.02 Additional Soil Characteristics The landscape architect for the project requested that the surficial soils at the site be tested for total metals and certain minerals and other plant nutrient characteristics. Composite soil samples were obtained by obtaining a soil sample from the upper 12 inches at three locations across the east and west half of the site. The samples from the three locations were mixed to develop two composite samples, one for the east half and the other for the west half. Composite 1 represents the west portion of the site and Composite 2 the eastern portion. OnSite Environmental tested the composite samples for total metals. AgSource Laboratories in Umatilla, Oregon tested the samples for nutrients and texture. The results of the soil tests are presented in Appendix C. PREVIOUS STUDIES GeoEngineers reviewed the logs of explorations completed as part of previous studies in the vicinity of the project site, including those completed by GeoEngineers for the design of the Covered Airpark and the Aviation High School. The location of the borings completed for the Aviation High School project closest to the project site are also shown in Figure 2. The boring logs from the borings shown on the Site Plan are presented in Appendix D. SITE CONDITIONS Setting and Site History The project site is located in the Duwamish Valley west of the Aviation High School and the Covered Airpark (currently under construction) in Tukwila, Washington, as shown in Figure 1. The project site is relatively flat. The south side of the project site is situated about 60 feet from Slip 6 which extends to the east off of the Duwamish River. The proposed plane foundation will be about 120 to 140 feet north and northeast of the slip. The site was originally developed in the 1930s for industrial purposes. The site was originally part of a larger parcel consisting of west and east parcels. The west parcel, abutting the Duwamish River, is where a large chemical processing plant operated. The east portion of the property (the portion of the historical site, now owned by the Museum) was used primarily for offices and lesser industrial facilities. The west and east parcels have been subject to numerous environmental assessments and cleanup actions. GeoEngineers previously completed a Phase I ESA on behalf of the Museum, the results of which are presented in our report for the Museum dated February 28, 2007. The Phase I Environmental Site Assessment (ESA) was completed as part of the Museum's due diligence prior to purchasing the east parcel from Container Properties, the previous property owner. At the time of the Phase I ESA, GeoEngineers concluded that the cleanup action had been successfully completed at the subject property and that no known or suspect environmental conditions were identified for the property with the exception of residual toluene in groundwater (and soil at the base of a remedial excavation) in the southwest portion of the property. These previous environmental cleanup actions consisted of remedial excavation of toluene and metals -contaminated soil across portions of the western half of the property. Additionally, an air sparging/vapor extraction system (AS/VE) is still operating in the southwest corner of the property to remediate toluene -contaminated groundwater remaining in this area of the property. This environmental GEOENGINEERS February 5, 2016 Page 2 Ale No.8039-010.02 action is ongoing under the direction of the Environmental Protection Agency (EPA) and is being conducted by the prior property owner, Container Properties. This remedial effort is unrelated to, and will not affect, the Museum's proposed B-52 display plans. GeoEngineers' Phase I ESA also concluded that "soil at the site may contain residual concentrations of hazardous substances (less than MTCA cleanup levels) that may require special handling and disposal procedures during site redevelopment." As a part of past clean-up activities by Container Properties, most of the project area was previously excavated to a depth of about 3 feet to remove contaminated soils. These areas were backfilled with clean fill material, but the report does not comment on the degree of compaction applied to the fill soils placed to restore grades. Site Geology Published geologic information for the project vicinity includes a United States Geological Survey Map titled "Geologic Map of Surficial Deposits in the Seattle 30' x 60' Quadrangle, Washington" (Yount et al., 1993) and "The Geologic Map of Seattle - A Progress Report" (Troost et al., 2005). The surficial soils in the vicinity of the site are mapped as alluvial deposits and modified land. The alluvial deposits generally consist of interbedded layers of soil ranging from clay to sand and gravel. These soils were deposited across the valley by the meandering of the Duwamish River, are as much as 250 feet thick and are poorly consolidated. The modified land in this area is typically dredged fill placed to develop Boeing Field and adjacent industrial areas. Surface Conditions The site is relatively level and consists of exposed soil across much of the site and some crushed gravel across other portions of the site. The north and east portions of the site are adjacent to parking areas used for the high school. A 747 and a 737 are currently being stored on the east portion of the site. A fence is present along the south and west boundaries of the site. A large 27-inch-diameter King County storm sewer is present diagonally across the site. Based on existing information, it appears that the invert for this storm drain is about 12 to 13 feet below existing grade. Subsurface Conditions Soil Conditions Based on the borings completed near the proposed foundation pads for the B-52, the soils within 30 feet of the surface consist mainly of surficial fill overlying mainly granular alluvial deposits. The fill consists of loose to medium dense silty sand with some gravel to stiff sandy silt and appears to be about 4 to 5 feet in thick. The fill is underlain by granular alluvial deposits consisting of loose to medium dense sand to silty sand with occasional interbedded layers of silt and sandy silt. A thin (2- to 3-foot-thick) layer of medium stiff silt was encountered within the sand deposits. This upper layer of silt was thicker (5 to 7 feet) in the borings completed for the high school. A clean sand deposit was encountered at a depth ranging from about 11 to 14 feet. At a depth of about 24 feet, the alluvium transitions back to interbedded silty sand and sandy silt deposits. Based on our explorations completed for Aviation High School and the Covered Airpark, we anticipate that below a depth of about 30 to 40 feet, the silt layers are thicker and more numerous. At a depth of about 60 to 65 feet, the upper interbedded granular and fine-grained alluvial deposits are underlain by deposits of soft silt and clay with varying amounts of silt and organic matter (lacustrine fine- grained soils). The soft lacustrine fine-grained soil deposits are underlain by medium dense to very dense GEOENGINEERSQ February 5, 2016I Page 3 File No. 8039-010-02 sand and gravel deposits which contain some shell fragments, suggesting that they were deposited in an estuarine environment. Groundwater Conditions Groundwater was generally encountered during drilling at depths ranging from 7 to 9 feet below the ground surface. Based on observations during construction of the high school and the Covered Airpark, we anticipate that the groundwater is typically at a depth of 9 to 12 feet except during extreme high tide events or prolonged periods of precipitation. Groundwater conditions should be expected to fluctuate as a function of season, precipitation, and tidal fluctuations of the Duwamish River and other factors. CONCLUSIONS AND RECOMMENDATIONS Based on the results of our subsurface explorations and our geotechnical engineering evaluations, it is our opinion that the foundation for the B-52 bomber can be supported on shallow spread foundations as currently planned. We estimate that the foundations might experience 1 to 2 inches of settlement, but understand that the display can tolerate this amount of settlement. We understand that the Museum and project team are aware that the site is underlain by thick granular deposits which are susceptible to liquefaction during a large earthquake. Therefore, if a large earthquake event occurred, additional settlement or lateral spreading into Slip 6 could impact the foundations; we understand that the Museum is willing to accept this risk. The foundations will be close to the existing King County Storm drain. However, as the invert of the storm drain is 12 to 13 feet below existing grade, in our opinion the loads from the plane will have minimal impacts on the storm drain. The upper fill soils contain sufficient fines that they will become soft and easily disturbed if wet. To minimize disturbance of the near -surface soils and allow for amending these soils for landscaping purposes, we recommend that the earthwork and grading be accomplished during the dryer months of the year. It will be difficult to reuse excavated on -site soil during wet weather. We previously prepared a soil handling plan for the Museum's use during construction for the Covered Airpark. For this project, we have recommended to the Museum and project team members that it should be a goal to keep soil on the property. Although this portion of the Museum's property has been remediated, the soil likely still contains chemicals that, although not a regulatory condition, would need to be tested and handled appropriately if taken off site. B-52 Foundation Support We recommend that the shallow foundations used to support the B-52 bomber be founded on a zone of properly compacted structural fill to provide more uniform support near the base of the foundation. We recommend that the foundations be founded on a layer of structural fill or crushed rock with a minimum thickness of 18 inches. The structural fill/crushed rock should be compacted to at least 95 percent of the maximum dry density (MDD) in general accordance with ASTM International (ASTM) D 1557. If sand is exposed at the base of the excavation, we recommend the exposed surface be recompacted. If silt is exposed along the base of the excavation, we recommend that a woven geotextile fabric such as Mirafi 500X be placed between the exposed soil and the new structural fill. The fabric will aid as a GEOENGINEERS� February 5, 2016 Page 4 File No. 8039-010-02 separation layer between the silt soil and the structural fill. The zone of structural fill should extend laterally beyond the footing edges a horizontal distance at least equal to the thickness of the fill where possible. All loose or disturbed soil must be removed prior to placing the structural fill pad. An allowable soil bearing value of 1,500 pounds per square foot (psf) may be used for support of the plane foundations supported on a zone of structural fill as described above. The allowable soil bearing value applies to the total of dead and long-term live loads and may be increased by up to one-third for wind or seismic loads. For this recommended bearing pressure, we anticipate that the footings will likely be about 7 to 10 feet in width and length to support the plane loads. We estimate that a new isolated footing subjected to a Tong -term dead load of 1,500 psf for a footing 10 feet square could experience between 1/2 and 1.5 inches of settlement. As discussed above, we understand that the owner recognizes that this type of foundation is susceptible to additional settlement if an earthquake induces liquefaction in the underlying soils. Lateral Resistance Lateral loads can be resisted by passive resistance on the sides of the footings and by friction on the base of the footings. Passive resistance should be evaluated using an equivalent fluid density of 350 pcf where footings are surrounded by structural fill compacted to at least 95 percent of MDD, as recommended. The structural fill should extend out at least a distance equal to two and one-half times the depth of the foundation element from its face. A passive pressure of 250 pcf should be used if the footing is poured directly against existing fill or native soils. These values also assume the ground surface in front of the footing will be level for a horizontal distance equal to at least two times the depth of the footing. If soils adjacent to footings are disturbed during construction, the disturbed soils must be recompacted, otherwise the lateral passive resistance value must be reduced. Resistance to passive pressure should be calculated from the bottom of adjacent paving or below a depth of 1 foot where the adjacent area is unpaved, as appropriate. Frictional resistance can be evaluated using 0.45 for the coefficient of base friction against footings which are underlain by structural fill. The above values incorporate a factor of safety of about 1.5. Earthwork and Structural Fill Excavation Considerations The near -surface soils encountered in the explorations typically consist of sand with variable amounts of silt, and silt. We anticipate that these soils can be excavated with conventional excavation equipment such as backhoes, trackhoes and dozers. We anticipate that most excavations required for the project will be relatively shallow, on the order of 2 to 4 feet in depth. At this time, we do not anticipate the need for shoring other than possibly the use of trench boxes or trench shields for utility trenches, which is discussed in the "Utility Considerations" section of this report. We anticipate that the depth of the excavations required for the foundations will generally be above the anticipated water level. Perched groundwater may be encountered above this depth if work takes place during or immediately after extended wet weather. We anticipate that the perched water can be handled during construction by sump pumping, as necessary. All collected water should be routed to suitable discharge points. GEOENGINEERS February 5, 20161 Page 5 File No. 8039-010-02 Temporary Cut Slopes All temporary cut slopes and shoring must comply with the provisions of Title 296 Washington Administrative Code (WAC), Part N, "Excavation, Trenching and Shoring." The contractor performing the work has the primary responsibility for protection of workers and adjacent improvements. We recommend temporary cut slope inclinations of 11hH:1V (horizontal to vertical) in the existing fill and alluvial deposits encountered at the site. Some caving/sloughing of the cut slopes may occur at this inclination. The inclination may need to be flattened by the contractor if significant caving/sloughing occurs. These cut slope recommendations apply to fully dewatered conditions. For open cuts at the site, we recommend that: • No traffic, construction equipment, stockpiles or building supplies be allowed at the top of the cut slopes within a distance of at least 5 feet from the top of the cut. • Exposed soil along the slope be protected from surface erosion using waterproof tarps or plastic sheeting. • Construction activities be scheduled so that the length of time the temporary cut is left open is reduced to the extent practicable. • Erosion control measures be implemented as appropriate such that runoff from the site is reduced to the extent practicable. • Surface water be diverted away from the excavation. • The general condition of the slopes be observed periodically by GeoEngineers to confirm adequate stability. Because the contractor has control of the construction operations, the contractor should be made responsible for the stability of cut slopes, as well as the safety of the excavations. The contractor should take all necessary steps to ensure the safety of the workers near slopes. Subgrade Preparation The on -site soils below the existing pavement contain a significant amount of fines (silt) and are moisture - sensitive. Operation of equipment on these exposed soils will be difficult under wet conditions. Disturbance of shallow subgrade soils should be expected if subgrade preparation work is done during periods of wet weather. We anticipate that either existing sand fill or native silt and sand will be exposed across the excavation. If sand or granular fill is exposed, we recommend recompacting the exposed footing subgrade to a dense and unyielding condition. If silt is exposed, as discussed above we recommend that a woven geotextile be placed across the subgrade after all loose soil removed. We anticipate that the depth of the excavation required for the foundation will generally be above the water table. Perched groundwater may be encountered if work takes place during or immediately after extended wet weather. We anticipate that the perched water can be handled during construction by sump pumping, as necessary. All collected water should be routed to suitable discharge points. GEOENGINEERSZ February 5, 20161 Page 6 File No. 8039 010.02 Structural Fill We understand the Museum desires to limit the amount of soil exported from the site. The on -site soils in the upper 5 feet typically consist of fine to medium sand with a high percentage of silt. Thus, the on -site sand may be considered for use as structural fill only for placement during periods of dry weather. This will likely not be practicable unless site work is completed during the normally dry summer months (July through September. Even if reused in landscape areas, the fill will be difficult to place and compact during wet weather. The following sections of this report present options for structural fill placement that will be dictated by the weather conditions. On -site Soils The surficial on -site near -surface soils are anticipated to consist of mainly silty fine to medium sand with gravel with some areas of sandy silt. In general, most of the on -site sand is anticipated to contain sufficient fines as to be moisture -sensitive and thus will be difficult to reuse as structural fill unless protected from rain during storage and placed and compacted during extended periods of dry weather. The silt should only be reused in landscape areas. Wet Weather Conditions If construction is planned for the wet winter months, we recommend that imported structural fill be included for construction of the foundation pads. Materials Materials used to support foundations, structures, roadways and parking areas are classified as structural fill for the purpose of this report. Structural fill material quality varies depending upon its use, as described below: • Structural fill to support the plane foundations should meet the criteria for common borrow as described in Section 9-03.14(3) of the 2014 Washington State Department of Transportation (WSDOT) Standard Specifications. Common borrow will be suitable for use as structural fill during dry weather conditions only. If structural fill is placed during wet weather, the structural fill should consist of gravel borrow as described in Section 9-03.14(1) of the WSDOT Standard Specifications, with the additional restriction that the fines content by limited to no more than 5 percent. Alternatively, the structural fill can consist of recycled concrete or crushed rock base course in conformance with Section 9-03.9(3) of the WSDOT Standard Specifications. • Structural fill placed as crushed surfacing base course below sidewalks and pavements should meet the requirements of crushed rock base course in conformance with Section 9-03.9(3) of the WSDOT Standard Specifications. Fill Placement and Compaction Criteria Structural fill should be mechanically compacted to a firm, non -yielding condition. Structural fill should be placed in loose lifts not exceeding 8 to 10 inches in thickness. Each lift should be conditioned to the proper moisture content and compacted to the specified density before placing subsequent lifts. Structural fill should be compacted to the following criteria: ■ Structural fill placed below foundations should be compacted to 95 percent of the MDD estimated in general accordance with ASTM D 1557. GEOENGINEERS� February 5, 2016 Page 7 File No. 8039-010-02 • Structural fill placed in pavement or sidewalk areas, including utility trench backfill, should be compacted to 90 percent of the MDD estimated in general accordance with ASTM D 1557, except that the upper 2 feet of fill below final subgrade should be compacted to 95 percent of the MDD. • Structural fill placed as crushed rock base course below pavements should be compacted to 95 percent of the MDD estimated in general accordance with ASTM D 1557. • Nonstructural fill, such as fill placed in landscape areas, should be compacted to at least 85 percent of the MDD estimated in general accordance with ASTM D 1557. In areas intended for future development, a higher degree of compaction should be considered to reduce the settlement potential of the fill soils. We recommend that a representative from our firm be present during placement of structural fill. Our representative will evaluate the adequacy of the subgrade soils and identify areas needing further work, perform in -place moisture -density tests in the fill to evaluate if the work is being done in accordance with the compaction specifications, and advise on any modifications to procedure that may be appropriate for the prevailing conditions. Erosion and Sedimentation Control Potential sources or causes of erosion and sedimentation depend upon construction methods, slope length and gradient, amount of soil exposed and/or disturbed, soil type, construction sequencing and weather. Implementing an erosion and sedimentation control plan will reduce the project impact on erosion -prone areas. The plan should be designed in accordance with applicable city, county and/or state standards. The plan should incorporate basic planning principles, including: • Scheduling grading and construction to reduce soil exposure; • Retaining existing asphalt whenever feasible; • Revegetating or mulching denuded areas; • Directing runoff away from denuded areas; • Reducing the length and steepness of slopes with exposed soils; • Decreasing runoff velocities; • Preparing drainage ways and outlets to handle concentrated or increased runoff; • Confining sediment to the project site; and • Inspecting and maintaining control measures frequently. In addition, we recommend that sloped surfaces in exposed or disturbed soil be restored so that surface runoff does not become channeled. Some sloughing and raveling of slopes with exposed or disturbed soil should be expected. Temporary erosion protection should be used and maintained in areas with exposed or disturbed soils to help reduce erosion and reduce transport of sediment to adjacent areas and receiving waters. Permanent erosion protection should be provided by paving or landscape planting. GEOENGINEERS February 5, 2016 Page 8 File No. 8039-010-02 Until the permanent erosion protection is established and the site is stabilized, site monitoring should be performed by qualified personnel to evaluate the effectiveness of the erosion control measures and to repair and/or modify them as appropriate. Provisions for modifications to the erosion control system based on monitoring observations should be included in the erosion and sedimentation control plan. Utility Considerations Shoring We anticipate that trench excavations required to install utilities and sewers will range from about 3 to 6 feet in depth. All temporary cut slopes and shoring must comply with the provisions of Title 296 WAC, Part N, "Excavation, Trenching and Shoring." The contractor performing the work has the primary responsibility for the protection of workers and adjacent improvements. Temporary shoring will be necessary to support excavations where space limitations restrict the use of open cuts. It may be desirable to excavate partially sloping cuts and use a trench box or other shoring for the lower few feet of the trench. Temporary trench shoring using internal bracing can be designed using active soil pressures. We recommend that temporary shoring be designed using a lateral pressure equal to an equivalent fluid density of 35 pcf for conditions with horizontal backfill adjacent to the excavation. These lateral soil pressures do not include traffic, structure or construction surcharges that should be added separately, if appropriate. Shoring should be designed for a traffic influence equal to a uniform lateral pressure of 100 psf acting over the depth of the trench. More conservative pressure values should be used if the designer deems them appropriate. These soil pressure recommendations are predicated upon the construction being essentially dewatered; therefore, hydrostatic water pressures are not included. If portions of the shoring use passive elements such as anchor or reaction blocks, available soil resistance can be estimated using passive soil pressures assuming an equivalent fluid density of 275 pcf above the water table and 130 pcf below the water table. The above -recommended lateral soil pressures do not include the effects of hydrostatic pressures or surcharges behind the wall. The effects of surcharge loads behind the shoring should be considered in design. If effective dewatering methods are used to lower the groundwater level below the bottom of the excavation, hydrostatic pressures need not be added to the soil pressures within the exposed height of shoring. Dewatering The groundwater across the project area is partially influenced by tidal fluctuations of the Duwamish River. In general, based on our observations during construction of the Space Gallery and the Aviation High School, we anticipate that the groundwater is typically 7 to 10 feet below existing grade. However, the groundwater levels could be higher during extreme high tides or during extended periods of heavy precipitation. Because the soils at the project consist mostly of sand with variable amounts of silt, we recommend that the groundwater table be maintained at least 2 feet below the planned bottom of the excavations during construction. Otherwise, excessive groundwater flow into excavations could cause lateral movement of the granular soils into the excavations, possibly destabilizing the excavations or causing excessive ground settlement adjacent to the excavations. We anticipate that the temporary dewatering system could likely consist of sumps, but other dewatering measures might be necessary GEOENGINEERS� February 5, 2016 Page 9 File No. 8039-010-02 depending on the construction sequence and time of year. The contractor should be responsible for the design and installation of the temporary dewatering systems required to complete the project. Pipe Bedding Pipeline bedding material should be placed and compacted on the trench subgrade or foundation material until a layer that is a minimum of 6 inches thick or one-fourth of the outside pipe diameter, whichever is greater, is achieved. Where soft or loose soils are encountered below the pipe alignment, we recommend they be removed to a depth of 12 inches below the invert, or to firm material as directed by the engineer. The pipe bedding material should conform to the pipe manufacturer's recommendations, the design engineer's recommendations, the 2014 WSDOT Standard Specification 9-03.12(3), Gravel Backfill for Pipe Zone Bedding or equivalent City standards. Precedence in case of a conflict should be with the design engineer. From a geotechnical standpoint, the native soils will not be suitable for bedding materials. If select import fill is used for the backfill, the trench backfill will' be more permeable than the surrounding soils and will fill with water over time. In this case, we recommend that all buried structures such as manholes be designed for uplift assuming that water will pond to within 5 feet of the top of the manholes. Trench Backfill After the pipe has been laid in the trench, the embedment material should be uniformly placed in maximum 8-inch-thick loose lifts on each side of the pipe, vibrated or otherwise compacted around the pipe haunches (i.e., at and below the pipe spring line) to the top of the zone. We recommend that trench backfill be compacted as recommended in the "Fill Placement and Compaction Criteria" section of this report. A geotechnical engineer should observe the preparation for, placement, and compaction of structural fill. An adequate number of in -place density tests should be performed in the fill to evaluate if the specified degree of compaction is being achieved. At all times during the placement of the pipeline and placement/compaction of the pipeline embedment material, it is the contractor's responsibility to protect the pipeline from damage (e.g., overstressing or impacting the pipeline with heavy equipment, etc.).

The approximate exploration locations were established in the field by measuring distances from existing site features. The borings were completed to depths ranging from 31.5 to 41.5 feet using mini -track drilling equipment, owned and operated by Geologic Drill of Nine Mile Falls, Washington. The borings were continuously monitored by a geotechnical engineer from our firm who examined and classified the soils encountered, obtained representative soil samples, and observed groundwater conditions. Our representative maintained a detailed log of each boring. Disturbed samples of the representative soil types were obtained using a 2-inch outside diameter standard penetration test (SPT) split -spoon sampler. One soil sample in each boring were obtained with a California sampler with a 3-inch outside diameter as a larger sample. The soils encountered in the test borings were typically sampled at 5-foot vertical intervals with the SPT split -spoon sampler through the full depth of the explorations. SPT sampling was performed using a 2-inch outside -diameter split -spoon sampler driven with a standard 140-pound hammer in accordance with ASTM D 1586, with the exception of where the California sampler was used. During the test, a sample is obtained by driving the sampler 18 inches into the soil with a hammer free -falling 30 inches. The number of blows required for each 6 inches of penetration is recorded. The Standard Penetration Resistance ("N-value") of the soil is calculated as the number of blows required for the final 12 inches of penetration (blows/foot). This resistance, or N-value, provides a measure of the relative density of granular soils and the relative consistency of cohesive soils. If the high penetration resistance encountered in the very dense soils precluded driving the total 18-inch sample interval, the penetration resistance for the partial penetration is entered on logs as follows: if the penetration is greater than 6 inches and less than 18 inches, then the number of blows is recorded over the number of inches driven; 30 blows for 6 inches and 50 blows for 3 inches, for instance, would be recorded as 80/9-inch. The blow counts are shown on the boring logs at the respective sample depths. The SPT is a useful quantitative tool from which soil density/consistency was evaluated. Soils encountered in the borings were classified in the field in general accordance with ASTM D 2488, the Standard Practice for Classification of Soils, Visual -Manual Procedure, which is summarized in Figure A-1. The boring log symbols are also described in Figure A-1, and logs of the borings are provided as Figures A-2 and A-3.

Log of Boring B-2 GEOENGINEERS.g Project: Project Location: Project Number: Museum of Flight B-52 Foundation Tukwila, Washington 8039-010-02 Figure A-3 Sheet 1 of 1 APPENDIX B Laboratory Testing APPENDIX B LABORATORY TESTING Soil samples obtained from the explorations were transported to our laboratory and evaluated to confirm or modify field classifications, as well as to evaluate engineering properties of the soil samples. Representative samples were selected for laboratory testing consisting of moisture content testing, percent fines (material passing the U.S. No. 200 sieve), sieve analyses and Atterberg Limits. The tests were performed in general accordance with test methods of the American Society for Testing and Materials (ASTM) or other applicable procedures. Additional soil chemical analytical testing was completed on some of the soil samples to provide a basis for developing general recommendations for soil handling during construction. The results of this testing is provided in a separate report dated September 25, 2014. Moisture Content and Density Testing Moisture contents and/or density tests were completed in general accordance with ASTM D 2216 and D 2937 for representative samples obtained from the explorations. The results of these tests are presented on the exploration logs in Appendix A at the depths at which the samples were obtained. Percent Passing U.S. No. 200 Sieve (%F) Selected samples were "washed" through the No. 200 mesh sieve to estimate the relative percentages of coarse and fine-grained particles in the soil. The percent passing value represents the percentage by weight of the sample finer than the U.S. No. 200 sieve. These tests were conducted to verify field descriptions and to estimate the fines content for analysis purposes. The tests were conducted in accordance with ASTM D 1140, and the results are shown on the exploration logs at the respective sample depths. Sieve Analyses Full sieve analyses were performed on one selected sample in general accordance with ASTM D-422. The wet sieve analysis method was used to determine the percentage of soil greater than the U.S. No. 200 mesh sieve. The results of the sieve analyses were plotted, classified in general accordance with the USCS, and presented in Figure B-1. Atterberg Limits Atterberg limits tests were used to classify the soils as well as to help determine the consolidation characteristics of the soils. The liquid limit and the plastic limit were determined in general accordance with ASTM D 4318. The results of the Atterberg limits testing indicated that the sample tested was non -plastic.

Geotechnical Services Are Performed for Specific Purposes, Persons and Projects This report has been prepared for the exclusive use of the Museum of Flight and other project team members for the Museum's B-52 project in Tukwila, Washington. This report may be made available to prospective contractors for their bidding or estimating purposes, but our report, conclusions and interpretations should not be construed as a warranty of the subsurface conditions. This report is not intended for use by others, and the information contained herein is not applicable to other sites. GeoEngineers structures our services to meet the specific needs of our clients. For example, a geotechnical or geologic study conducted for a civil engineer or architect may not fulfill the needs of a construction contractor or even another civil engineer or architect that are involved in the same project. Because each geotechnical or geologic study is unique, each geotechnical engineering or geologic report is unique, prepared solely for the specific client and project site. Our report is prepared for the exclusive use of our Client. No other party may rely on the product of our services unless we agree in advance to such reliance in writing. This is to provide our firm with reasonable protection against open-ended liability claims by third parties with which there would otherwise be no contractual limits to their actions. Within the limitations of scope, schedule and budget, our services have been executed in accordance with our Agreement with the Client and generally accepted geotechnical practices in this area at the time this report was prepared. This report should not be applied for any purpose or project except the one originally contemplated. A Geotechnical Engineering or Geologic Report Is Based on a Unique Set of Project -Specific Factors This report has been prepared for the Museum of Flight B-52 project in Tukwila, Washington. GeoEngineers considered a number of unique, project -specific factors when establishing the scope of services for this project and report. Unless GeoEngineers specifically indicates otherwise, do not rely on this report if it was: • not prepared for you, • not prepared for your project, • not prepared for the specific site explored, or • Completed before important project changes were made. For example, changes that can affect the applicability of this report include those that affect: • the function of the proposed structure; • elevation, configuration, location, orientation or weight of the proposed structure; • composition of the design team; or • project ownership. 1 Developed based on material provided by ASFE, Professional Firms Practicing in the Geosciences; www.asfe.org . GEOENGINEERS February 5, 2016 Page E-1 File No. 8039-010-02 If important changes are made after the date of this report, GeoEngineers should be given the opportunity to review our interpretations and recommendations and provide written modifications or confirmation, as appropriate. Subsurface Conditions Can Change This geotechnical or geologic report is based on conditions that existed at the time the study was performed. The findings and conclusions of this report may be affected by the passage of time, by manmade events such as construction on or adjacent to the site, or by natural events such as floods, earthquakes, slope instability or groundwater fluctuations. Always contact GeoEngineers before applying a report to determine if it remains applicable. Most Geotechnical and Geologic Findings Are Professional Opinions Our interpretations of subsurface conditions are based on field observations from widely spaced sampling locations at the site. Site exploration identifies subsurface conditions only at those points where subsurface tests are conducted or samples are taken. GeoEngineers reviewed field and laboratory data and then applied our professional judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface conditions may differ, sometimes significantly, from those indicated in this report. Our report, conclusions and interpretations should not be construed as a warranty of the subsurface conditions. Geotechnical Engineering Report Recommendations Are Not Final Do not over -rely on the preliminary construction recommendations included in this report. These recommendations are not final, because they were developed principally from GeoEngineers' professional judgment and opinion. GeoEngineers' recommendations can be finalized only by observing actual subsurface conditions revealed during construction. GeoEngineers cannot assume responsibility or liability for this report's recommendations if we do not perform construction observation. Sufficient monitoring, testing and consultation by GeoEngineers should be provided during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes should the conditions revealed during the work differ from those anticipated, and to evaluate whether or not earthwork activities are completed in accordance with our recommendations. Retaining GeoEngineers for construction observation for this project is the most effective method of managing the risks associated with unanticipated conditions. A Geotechnical Engineering or Geologic Report Could Be Subject to Misinterpretation Misinterpretation of this report by other design team members can result in costly problems. You could lower that risk by having GeoEngineers confer with appropriate members of the design team after submitting the report. Also retain GeoEngineers to review pertinent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering or geologic report. Reduce that risk by having GeoEngineers participate in pre -bid and preconstruction conferences, and by providing construction observation. GEOENGINEERSQ February 5, 2016 1 Page E-2 File No. 8039.010.02 Do Not Redraw the Exploration Logs Geotechnical engineers and geologists prepare final boring and testing logs based upon their interpretation of field logs and laboratory data. To prevent errors or omissions, the logs included in a geotechnical engineering or geologic report should never be redrawn for inclusion in architectural or other design drawings. Only photographic or electronic reproduction is acceptable, but recognize that separating logs from the report can elevate risk. Give Contractors a Complete Report and Guidance Some owners and design professionals believe they can make contractors liable for unanticipated subsurface conditions by limiting what they provide for bid preparation. To help prevent costly problems, give contractors the complete geotechnical engineering or geologic report, but preface it with a clearly written letter of transmittal. In that letter, advise contractors that the report was not prepared for purposes of bid development and that the report's accuracy is limited; encourage them to confer with GeoEngineers and/or to conduct additional study to obtain the specific types of information they need or prefer. A pre -bid conference can also be valuable. Be sure contractors have sufficient time to perform additional study. Only then might an owner be in a position to give contractors the best information available, while requiring them to at least share the financial responsibilities stemming from unanticipated conditions. Further, a contingency for unanticipated conditions should be included in your project budget and schedule. Contractors Are Responsible for Site Safety on Their Own Construction Projects Our geotechnical recommendations are not intended to direct the contractor's procedures, methods, schedule or management of the work site. The contractor is solely responsible for job site safety and for managing construction operations to minimize risks to on -site personnel and to adjacent properties. Read These Provisions Closely Some clients, design professionals and contractors may not recognize that the geoscience practices (geotechnical engineering or geology) are far less exact than other engineering and natural science disciplines. This lack of understanding can create unrealistic expectations that could lead to disappointments, claims and disputes. GeoEngineers includes these explanatory "limitations" provisions in our reports to help reduce such risks. Please confer with GeoEngineers if you are unclear how these "Report Limitations and Guidelines for Use" apply to your project or site. Geotechnical, Geologic and Environmental Reports Should Not Be Interchanged The equipment, techniques and personnel used to perform an environmental study differ significantly from those used to perform a geotechnical or geologic study and vice versa. For that reason, a geotechnical engineering or geologic report does not usually relate any environmental findings, conclusions or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Similarly, environmental reports are not used to address geotechnical or geologic concerns regarding a specific project.

The report has been prepared using the 2009 King County Surface Water Design Manual (KCSWDM) as a general guideline for this abbreviated Stormwater Technical Information Report (TIR). In some cases the information requested in the KCSWDM is specific to permitting in King County. Requested information that is directly related to work in King County has been omitted from this TIR. The project is located in the City of Tukwila directly southwest of Raisbeck Aviation High School (9229 East Marginal Way South), north of S 94th Place, in the southwestern -most portion of Parcel Number 572980-0010. See Figure 1-1 for a vicinity map showing the location of the site. The project site is currently owned by the Museum of Flight and was formerly owned by Container Properties. Work on the site will be completed in two phases. Phase 1 of the Park project, completed in Summer 2016, included the reconfiguration of the existing adjacent parking, the removal of asphalt pavement, the development of lawn areas, installation of an irrigation system, a new water service for irrigation, and the installation of a pervious gravel area for picnic tables. No significant grading was done for Phase 1. There have been no further site improvements since the completion of Phase 1. The scope of work for Phase 2 will create a landscaped area of natural vegetation, plantings, gravel pathways, and a raised concrete plaza mound with a commemorative statue and flagpoles. All of these improvements are part of an exhibit for restored B-52 aircraft. The project will also include foundations to support the aircraft, irrigation and lighting and removal of trees. The Phase 1 and 2 work were approved as a Planned Action in March 2016. Because this is a phased development, the land cover prior to the start of the Phase 1 improvements is considered the predeveloped condition for the purposes of this TIR. EXISTING DRAINAGE Prior to the commencement of Phase 1, the site was entirely impervious consisting of asphalt or concrete paving and compacted soil and gravel surfacing. Aerial images dating as far back as 1990 show that this site has been impervious since at least that time. A portion of the site currently drains to an existing on -site conveyance on the on the Raisbeck Aviation High School property which discharges to the Duwamish River through an existing 36-inch outfall, owned•by King County, at the northeast corner of Slip 6; This conveyance system was installed during the construction of Raisbeck Aviation High School. This conveyance system connects to an existing storm drain system that includes the King County outfall on the high school site. This system includes a water quality treatment device (StormFilter), installed by the high school project, that treats the pollution - generating impervious surfaces created by that project. The King County outfall also collects discharge from adjacent properties on the west side of East Marginal Way South as well as a portion of the runoff from the King County International Airport. Stormwater Technical Information Report 1 B-52 Memorial Park Phase 2, Tukwila, Washington MAGNUSSON ri KLEMENCIC .1 ASSOCIATES ■ The reminder of the site has no collection or conveyance system and discharges as overland flow to the adjacent Container Properties site. The site drainage area, site characteristics, and the existing storm drain conveyance system are shown in Figure 1-2. PROPOSED DRAINAGE The Phase 1 drainage did not modify the existing drainage system and the catchment areas draining to the existing conveyance systems were maintained. No new conveyance systems were installed. Phase 2 will maintain all existing drainage systems and there are no proposed improvements. Overall peak flow rates will be reduced as a result of the reduction in impervious surfaces. SECTION 2: CONDITIONS AND REQUIREMENTS SUMMARY SITE CONDITIONS • The site disturbance within the Phase 2 limits of work is 0.83 acres as shown on Figure 2-1. Areas of Phase 2 were previously disturbed for the Phase 1 work. • The existing pervious and impervious areas, prior to Phase 1, within the Phase 2 limits of work, are 0.06 acres and 0.88 acres respectively. See Figure 2-2. • The proposed pervious and impervious areas, after the completion of the Phase2 work, within the Phase 2 limits of work are 0.66 acres and 0.27 acres respectively. See Figure 2-3. This represents an increase to the pervious area, and corresponding decrease to the impervious area, of 0.61 acres. • Prior to the Phase 1 work, the existing pollution -generating impervious surface area within the site disturbance area was 2,571 square feet. All pollution -generating impervious surface areas within the site disturbance area were removed as part of the Phase 1 work. There are not proposed pollution -generating surfaces proposed for Phase 2. CORE REQUIREMENTS Evaluation of the project with respect to the Core and Special Requirements is outlined below. Core Requirement 1: Discharge at the Natural Location The drainage from the site disturbance area will continue to drain to the existing off -site systems on the Container Properties site and Raisbeck Aviation High School, which eventually discharge to outfalls at the Duwamish River. Core Requirement 2: Off -Site Analysis Not applicable. The proposed development reduces the impervious surface and as a result there is no adverse change to the rate, volume, duration, or location of discharges to and from the site. Stormwater Technical Information Report 2 B-52 Memorial Park Phase 2, Tukwila, Washington MAGNUSSON KLEMENCIC 11 ASSOCIATES ■ Core Requirement 3: Flow Control Not applicable. The project is within the Duwamish River Basin and discharges via a closed conveyance system, with adequate capacity, to a point below River Mile 6, and is therefore exempt from the flow control requirement. Core Requirement 4: Conveyance System There are no new conveyance systems required for this project. Existing on -site conveyance lines have not been analyzed since there is a decrease to the to the peak flow rate as a result of the decrease in impervious area within the site disturbance area. Core Requirement 5: Temporary Erosion and Sedimentation Control A Temporary Erosion and Sedimentation Control (TESC) plan has been prepared for the project. Core Requirement 6: Maintenance and Operation There is an existing water quality treatment facility on the Raisbeck Aviation High School site. Maintenance and operation of this facility is by the high school. Core Requirement 7: Financial Guarantees and Liability Not applicable. This is a requirement specifically related to work in unincorporated King County. Core Requirement 8: Water Quality There will be no new or replaced pollution -generating impervious surface. Additional water quality treatment beyond what currently exists on the high school site is not required. Pollution -generating impervious surface areas were reduced as a result of the removal of asphalt paved parking areas in Phase 1. There no new pollution -generating surfaces proposed for Phase 2. SPECIAL REQUIREMENTS Special Requirement 1: Other Adopted Area -Specific Requirements Not applicable. Special Requirement 2: Flood Hazard Area Delineation Not applicable. The project site appears on the National Flood Insurance Rate Map, dated May 16, 1995, Community Panel No. 53033C0645F, and is situated in Zone "X," an area determined to be outside the 500-year floodplain. Special Requirement 3: Flood Protection Facilities Not applicable. There are no flood protection facilities on the project site.

TESC Requirement 11: Final Stabilization Final stabilization will be in accordance with the final paving and landscape plans for the project. STORMWATER POLLUTION PREVENTION AND SPILL PLAN DURING CONSTRUCTION Best management practices (BMPs) to prevent pollution from construction activities, in addition to the TESC requirements, shall be implemented during construction. These BMPs are based on the activity sheets in the 2009 King County Stormwater Pollution Prevention Manual. Activity Sheet A-4 — Storage of Soil, Sand, and Other Erodible Materials • Cover and contain the stockpiles of raw materials to prevent stormwater from washing material to surface waters or a storm drainage system. The covers must be in place at all times when the stockpile is not in active use. Do not hose down the contained stockpile area to the storm drainage system. • Stockpiles located away from paved areas or where material will not be washed or tracked to the storm drainage system may not need to be covered unless windy conditions cause airborne particulate that could settle on hard surfaces and subsequently be washed into adjacent surface waters or storm drainage systems. • If the stockpiles are so large that they cannot feasibly be covered and contained, implement erosion control practices at the perimeter and as needed on site to prevent erosion and runoff of the stockpiled material into the storm drainage system or off site. See the King County Surface Water Design Manual, Appendix D (Erosion and Sediment Control Standards). • Required routine maintenance: — Sweep paved storage areas as needed and collect and dispose of loose solid materials. Do not hose down the area to a storm drain or ditch. — Stock cleanup materials, such as brooms, dustpans, and vacuum sweepers near the storage area. Activity Sheet A-11 — Cleaning or Washing of Tools and Equipment • Tool and equipment wash water is considered process water, and must discharge to the sanitary sewer, a holding tank, or a process treatment system, regardless of the washing method used. • You are encouraged to recycle your wash water with an enclosed loop system or use self-contained parts washers. Numerous products are commercially available that recycle and contain wash water and cleaning solvents. Stormwater Technical Information Report 6 B-52 Memorial Park Phase 2, Tukwila, Washington MAGNUSSON '1 KLEMENCIC J ASSOCIATES ■ • If you cannot connect discharges to a sanitary sewer, process treatment system, or holding tank, you must contact the Washington State Department of Ecology and go through the Individual Wastewater Discharge permit process. • Lawnmowers may be rinsed with water only on a lawn or similar area as long as the rinsed -off grass clippings will not be washed to the storm drain system or surface waters when it rains. Wash water from oily or similarly contaminated lawn maintenance equipment is not allowed to flow to or discharge to any stormwater system or surface water. Activity Sheet A-20 — Concrete and Asphalt Application • Sweep parking lots, storage areas, and driveways as needed to collect dirt, waste, and debris. Do not hose down the area to the storm drainage system. • Cover and contain all nearby storm drains at the beginning of the workday. Drain covers and other containment devices are commercially available to keep runoff out of the storm drainage system. All solids collected must be disposed of properly at the end of the workday (or more frequently) prior to removing the containment or cover device(s). • Contain and collect the slurry from exposed aggregate washing. Never allow the slurry to get into a storm drain, ditch, roadway shoulder or gutter. Use a storm drain cover, inlet protection, or other containment device, such as a hand —dug, lined sump, to direct and contain slurry. All collected runoff must be disposed of properly. • Do not discharge concrete, slurry, or rinse water into gutters, storm drains, or drainage ditches or onto the paved surface of a roadway or driveway. • Designate an area on site where hand tools will be cleaned and the water collected for disposal. Commercial products and services are also available for concrete, slurry, and rinse water containment and disposal. • Sweep the pouring area at the end of the job or more frequently if needed. Collect loose aggregate chunks and dust. Do not hose down the area to a storm drain. Activity Sheet A-31 — Vehicle and Equipment Parking and Storage • Sweep parking lots, storage areas, and driveways as needed to collect dirt, waste, and debris. Do not hose down the area to the storm drainage system. • If washing/pressure washing of the parking lot occurs, the wash water must be collected and discharged to a sanitary sewer or other treatment system. There are services that will clean parking lots and collect water for off -site disposal. Never drain wash water to the storm drainage system. • Gravel and dirt lots may require additional BMPs to prevent sediment -laden water from leaving the site. Vehicles can track dirt out of parking and storage areas onto public roadways. Basic sediment controls as outlined in Appendix D ("Erosion and Sediment Control Standards") of the King County Surface Water Design Manual must be installed if other BMPs do not adequately control sediment laden water from entering off site storm water conveyance systems or surface water. Wheel wash Stormwater Technical Information Report 7 B-52 Memorial Park Phase 2, Tukwila, Washington MAGNUSSON KLEMENCIC .1 ASSOCIATES • facilities may need to be considered if track -out of mud becomes a problem. See Activity Sheet A- 41, "Wheel Wash and Tire Bath Operations." Activity Sheet A-42 — Potable Water Line Flushing or Tank Maintenance • When flushing water lines, filter water through sediment traps. If super -chlorination or chemical treatment is used as part of flushing, the water must be discharged to the sanitary sewer (with applicable permits) or, if a sanitary sewer is not available, the water must be collected and disposed of appropriately. Water cannot be discharged directly to stormwater systems unless it is treated and water quality standards are met. Discharging treated water to stormwater systems requires approval from the Washington State Department of Ecology. Activity Sheet A-44 — Dust Control and Soil Erosion and Sediment Control for Manufacturing and Other Commercial Operations • Sweep paved areas as needed where dust accumulates from commercial, manufacturing, and industrial operations. Use power vacuum cleaners and sweepers as appropriate to minimize generating airborne dust and for more efficient dust removal. • Regularly clean equipment and vehicles subject to dust accumulation from operations. Never wash down equipment or vehicles to the storm drainage system. • Stabilize or cover areas of exposed or disturbed soil where necessary to prevent soil erosion. See the King County Surface Water Design Manual, Appendix D, Erosion and Sediment Control Standards, for recommended erosion and sediment control practices and standards. • Ensure employees are trained in the proper operating procedures to minimize dust accumulation on the ground. SECTION 9: BOND QUANTITIES WORKSHEET, RETENTION/DETENTION FACILITY SUMMARY SHEET AND DECLARATION OF COVENANT Not applicable. This item is specific to work in unincorporated King County. SECTION 10: OPERATIONS AND MAINTENANCE MANUAL Not applicable. There are no new flow control or water quality facilities proposed for this project.

Marginal Way Facility WAD 00928 2302 Dear Mr. Dupuy: The U.S. Environmental Protection Agency, Region 10 received the East Parcel Corrective Measures Implementation Operations and Maintenance Report, 2016 dated March 2017 (Report). The purpose of the Report is to evaluate the performance of corrective measures to remediate the toluene -impacted groundwater in the East Parcel Corrective Measures Implementation (CMI) project area. The Report surrunarizes the results of the final round of quarterly groundwater monitoring completed in June 2016,. and serves as the final CMI report for the East Parcel. In Section 4.0 of the Report, the Respondents request fonnal acknowledgment of completion of the East Parcel CMI. Pursuant to Paragraph 7.1 of the Order, the EPA approves the Report. The EPA also acknowledges that corrective measures for the East Parcel are complete, and this letter serves as the final determination of Corrective Action Complete without Controls for the East Parcel. This determination applies only to the East Parcel; separate work continues on the West Parcel under the Order. In 2006, the Respondents extensively investigated and remediated contamination at the East Parcel and sold the property to the Museum of Flight. The EPA issued a partial determination of Corrective Action Complete without Controls for the East Parcel via a letter on December 20, 2006. The determination covered all portions of the East Parcel except a small area in the southwest corner where toluene was suspected to remain present in groundwater. The EPA presented final decisions regarding corrective action for the East Parcel in the 2006 letter. Corrective actions included source area excavation and removal as the final remedy, and a contingency to address any residual toluene in groundwater if source removal did not prove to be an effective groundwater remedy. If within six months of remedy selection, the Respondents could demonstrate that the concentration of toluene in groundwater was below the final groundwater cleanup level (1.0 rng/L), corrective measures would be deemed complete. However, the Respondents could not meet the requirement and developed a work plan to implement additional corrective measures for groundwater in accordance with the contingent remedy. The EPA approved the CMI work plan in 2007 for the East Parcel groundwater remediation. The initial groundwater remedy consisted of a biosparge and vent well system, which was installed in 2008. Soil vapor initially was treated using granular activated carbon through 2008, then by a soil vapor extraction - internal combustion engine system through 2009. In 2010, the EPA approved shutting down active operation of the biosparge/vent system and continuing to monitor the toluene groundwater concentrations for four post -shutdown sampling events. Because of rebound of toluene groundwater concentrations that exceeded the cleanup level, the Respondents restarted the biosparge system in 2012. The EPA approved shut down of the system in-2015 after several consecutive quarterly sampling events demonstrated that toluene remained below the groundwater cleanup level. After four consecutive post - shutdown sampling events during which toluene was not detected, the Respondents dismantled the system in 2016 upon the EPA's approval. The final sampling event in June 2016 narked the thirteenth consecutive quarter in which toluene levels were below the cleanup level, and the tenth consecutive event in which toluene was not detected above the analytical reporting limit. This final determination of Corrective Action Complete without Controls means that the EPA, under authority of the Order, has determined that remedies for the entirety of the East Parcel have been impleme►rted successfully and no fin -Vier activities or controls are necessary, and that human health and ecological risks have been appropriately addressed. if you have any questions regarding this letter, please contact Janette Knittel at (206) 553-0483 or knittel.janette(Nepa.gov, or your legal counsel may contact Jennifer MacDonald at (206) 553-8311 or niacdonald.jennifer@epa.gov. cc: Mr. Chintan Amin Bayer CropScience Mr. David Blount Landye Bennett Blurstcin LLP Mr. Jalnes .1.

As you'll recall, we had prepared an archaeological monitoring plan calling for monitoring of all excavation between 4-10 feet below the existing ground surface. Sediments in the upper four feet were deposited during a cleanup operation in 2006. At the time the monitoring plan was prepared, project plans called for tie -downs for the B-52 aircraft that would be supported on auger -cast pilings to 40 feet below the surface, and installation of those pilings was to be monitored. Since that monitoring plan was prepared, project plans have changed. The tie -downs will now be supported on footings that will be excavated less than 4 feet into the existing surface, and then imported fill will be placed atop. Please see the attached PDF for details. At this time, the project team does not expect any excavation below 4 feet below the existing ground surface and all ground disturbance should be within clean sediments deposited during the 2006 cleanup. Therefore, monitoring is no longer needed. However, Anchor QEA will remain on -call in the event of any inadvertent discoveries. The construction team has been briefed on the Inadvertent Discovery Plan. Please feel free to contact me if you have any questions. Thanks, Barbara Barbara E.

This project will display a B-52 bomber on the Museum of Flight's property across the street from the main museum, near Slip 6 of the Lower Duwamish Waterway. Installation of the aircraft will require deep foundations for two tie -downs (a total of eight 18-inch diameter auger -cast pilings). DAHP requested an archaeological survey. On behalf of the Museum of Flight, Anchor QEA prepared the attached Cultural Resources Assessment, and uploaded it to the WISAARD database yesterday. It is provided for your review. In summary, there was a cleanup action at the location in 2007 that removed contaminated sediments and placed 4-7 feet of fill across the project area. Native sediments would be difficult to reach with standard archaeological techniques, and it is fairly likely that the original ground surface was removed during the cleanup. However, given the sensitivity of the Duwamish River area and the requirements of Tukwila Municipal Code 18.50.110, we have recommended monitoring during construction. 2 The City of Tukwila and King County are copied on this email.

PROJECT DESCRIPTION This project proposes to create a permanent exhibit of a B-52G Stratofortress 59-2584 Midnight Express aircraft and a Veteran's Memorial Plaza in a park -like setting which will be open to the public as part of the Museum of Flight. On -site work includes constructing deep foundations for two tie -downs (a total of eight 18-inch diameter auger -cast pilings) to support the B-52 aircraft, a 650 square -foot rain garden, landscaping, walkways of permeable pavement, and a plaza. The plaza will consist of a low seating wall, a statue depicting a returning aviator honoring veterans, 7 flag poles, educational exhibits, and lighting (see Figure 1). Due to direct conflicts with the proposed B-52 wing location, 13 existing trees along the south property line will be removed, requiring 80 replacement trees in conformance with TMC 18.44.080.B. 23 replacement trees will be planted on -site and in -lieu fees for the remaining 57 trees will be paid into the City's tree replacement fund. Project Site The project site is part of a larger parcel located at 9229 E. Marginal Way South (Parcel #5729800010) and outlined in red in the Figure 2 below. Paved parking areas for Aviation High School and adjacent office uses surround the project site on the north and east sides. Aviation High School and the Museum of Flight's Aviation Pavilion are situated nearby, east of the project site. The site is separated from Slip 6 of the Duwamish River on the south side by a strip of land approximately 25 feet wide owned by the Boeing Company. The site has no direct access to the River. There is an existing King County storm drain easement running diagonal on the site from the southwest towards the northeast. Remaining on -site are three trailers currently accommodating the ongoing operations and activities of the Boeing Employees Amateur Radio Society (B.E.A.R.S.). The trailers house sensitive communication antennae and equipment, and provide emergency communication services for Boeing and the local public service communities. The site is relatively flat and consists of exposed soil across much of the site and some crushed gravel. The Museum has undertaken clean-up actions on the site over the past 10 years and it was found to be successfully remediated of hazardous materials per the Environmental Protection Agency in 2017. Existing trees on the site include 13 tall, mature trees along the 2 July 19, 2018 Shoreline Substantial Development • • southern property line, including 11 Lombardi poplars and 2 native Bitter cherries.

TUKWILA SHORELINE MASTER PROGRAM The City of Tukwila adopted a new Shoreline Master Program (SMP) on August 15, 2011 which was approved by the Washington State Department of Ecology on October 14, 2011 and became effective October 28, 2011. This project is subject to the new Shoreline Master Program. A. SHORELINE ENVIRONMENT DESIGNATION The shoreline environment designation for the site is High Intensity; the purpose of the High Intensity environment is to focus on water -oriented commercial, transportation, and industrial uses, with a priority on water -dependent uses. Non -water oriented uses should not be allowed except as part of a mixed use development, in limited situations where they would not conflict with or limit opportunities for water -oriented uses, or on sites where there is no direct access to the shoreline. New development should promote vegetation conservation and enhancement, sensitive areas protection, and preservation of water quality to assure no net Toss of shoreline ecological functions. Visual and public access should be provided, where feasible. The shoreline buffer in the High Intensity environment is measured as 100 feet from the OHWM of the Duwamish River. A portion of the B-52 Memorial Park project, including one support structure for the B-52 aircraft landing gear, a rain garden, landscaping, and walkways of permeable pavement fall within the 100 foot shoreline buffer. Other project elements, including the two deep foundations for two tie -downs (a total of eight 18-inch diameter auger - cast pilings) for the aircraft and the half of the park plaza, lie outside the buffer but within the 4 Shoreline Substantial Develor^^^^t July 19, 2018 per year and employs nearly 200 people. The B-52 Park will add an additional exhibit of a restored B-52G, while maintaining visual access to the river and an ecologically restored park area for visitors to enjoy. The applicant feels this use meets the goals for both economic vitality and preserving the benefits of the river. The B-52 project site is within the shoreline buffer but is separated from the actual high-water line by a 25' strip of land owned by the Boeing Company so that there is no direct access to the river from the project site. Shoreline access is controlled by the Boeing Company. The applicant believes that the development of the B-52 park provides flexibility for future development or shoreline function in that it has no permanent structures other than footings for the aircraft in the shoreline buffer area. Staff concurs with the applicant's response. The applicant has also provided a No Net Loss (NNL) checklist which is provided as Attachment 4 to this staff report. A NNL analysis of shoreline function was not required of the applicant, as the applicant is improving the existing soil, water, and shoreline jurisdictions conditions. Prior to the improvements, the site consisted of compacted gravel paving. Park improvements will include landscaping, a rain garden, and permeable paving, resulting in better soil stabilization, improved runoff water quality, and enhanced habitat for wildlife. 6.6 Access and Recreational Use Goal: Increase the amount and diversity of opportunities for public recreation and access to and along the river, including visual and cultural access, access to the water's edge, opportunities for small boat navigation and access, and connections to other neighborhoods, consistent with the shoreline character. Applicant Response: The B-52 project site is within the shoreline buffer, but is separated from the actual high-water line by a 25 foot strip of land owned by the Boeing Company so that there is no direct access to the river from the project site. However, the applicant is creating a park space that will be open to the public with many recreational amenities, including a loop path around the aircraft and a memorial plaza located on a raised mound surrounded by lawn from which one can view to the river. Staff concurs with the applicant's response. Policy 5.6.14: For MIC properties not included in the King County Green River Trail Plan, require shoreline development to provide public access or a private natural area in lieu of public access, or otherwise mitigate the loss of public access. Applicant Response: The B-52 project is providing nearly an acre of open space with a native meadow planting, raingarden, loop path and memorial plaza. Because the project site is not directly adjacent to the river and is very flat, views from the southwest corner nearest the high- water line are not very clear. Therefore, the plaza area will be raised to allow for views to the 6 Shoreline Substantial Development July 19, 2018 200 foot shoreline jurisdiction. There is a small portion of the site that is located completely outside of the shoreline environment — see Figure 3. 200' from OHWM Figure 3.

SHORELINE MASTER PROGRAM GOALS AND POLICIES The following section discusses the Shoreline Master Program (SMP) goals and policies that apply to this project and are excerpted from Chapter 6 of the City's SMP. 6.3 Land Development Use and Economic Vitality Goal: Development along the shoreline that fosters the economic vitality of Tukwila while preserving the long-term benefits of the river. Policy 5.3.8: Ensure that non -water dependent shoreline development in the MIC provides for shoreline multiple uses to the extent that site security and the success of industrial operations are not jeopardized; ensures no net loss of shoreline function and provides adequate mitigation for the loss of shoreline multiple use opportunities. Applicant Response: The Museum of Flight (MOF) B-52 Park is an extension of the Museum of Flight Air Pavilion, and the greater Museum complex. The MOF draws over half a million visitors 5 Shoreline Substantial Development July 19, 2018 river. The plaza and paths all meet ADA requirements, and furnishings including benches, handrails, and site lighting are provided. The park plantings are native/adaptive in accordance with Vegetation Protection and Landscaping section of the Tukwila Shoreline Master Program, and any tree removal is being either replaced or paid for by the Museum in lieu of planting additional trees, based on the restrictions inherent in our program. Staff concurs with the applicant's response. The project site is not included in the King County Green River Trail Plan. Policy 5.10.1: Design, locate, and manage shoreline development including streets, flood control projects, surface water drainage and sewer systems, clearing and grading activities, and landscaping in a manner which minimizes opportunities for pollutants to enter the river, provides erosion control and otherwise protects water quality. Applicant Response: Minimal grading will occur on the site. The former compacted gravel parking area was de -compacted and replaced with hydroseeded meadow as part of the first phase of this project, which has been completed. Next phases will enhance the meadow and add additional planting and permeable paving. At the low point of the site where water currently pools, a rain garden will be added to increase infiltration and filter any pollutants that may be carried with runoff across the site. Staff concurs with the applicant's response. 5. SHORELINE REGULATIONS TMC 18.44.130.B.3. Shoreline Administration states that a substantial development permit shall be granted only when the development proposed is consistent with the shoreline master program. The relevant SMP policies were discussed above. Below is a discussion of the relevant shoreline master program regulations that are incorporated into the zoning code that apply to this permit application. A. Permitted Uses: TMC 18.44.060 identifies permitted uses in the High Intensity environment. Under TMC 18.44.060.B.1 the following components of the proposed project are listed as permitted uses in the High Intensity buffer (100 feet from OHWM): c. Public parks, recreation and open space. d. Public and/or private promenades, footpaths or trails. f. Recreation structures such as benches, tables, viewpoints, and picnic shelters, provided no such structure shall exceed 15 feet in height and 25 square feet in area and no views of the shoreline are blocked from adjacent properties. Project elements within the High Intensity buffer consist of one support structure for the B-52 aircraft landing gear, a rain garden, landscaping, and walkways of permeable pavement. 7 Shoreline Substantial Develop^,^^t July 19, 2018 TMC 18.44.060.C.1 sets forth the permitted uses in the High Intensity environment area located outside of the buffer (within 200 feet of the OHWM): "All uses permitted in the High Intensity Buffer and/or the Shoreline Use Matrix may be allowed." Project elements within this area are considered permitted uses, consisting of two deep foundations for two tie -downs (a total of eight 18-inch diameter auger -cast pilings) to support the B-52 aircraft, landscaping, walkways of permeable pavement, and a plaza. The plaza will consist of a low seating wall, a statue depicting a returning aviator honoring veterans, 2 of the 7 flag poles, educational exhibits, and lighting. B. Development Standards - TMC 18.44.070.0 The following development standards apply to this project. • TMC 18.44.070.C.1 Standards — The proposed project meets the development standards for the underlying Manufacturing Industrial Center/Heavy Industrial (MIC/H) zone. • TMC 18.44.070.C.2. Setbacks and site configuration - The yard setback adjacent to the river is 100 feet. The one structure proposed within the buffer is an undercarriage support for the aircraft's wingtip which will be 8 feet in height and is a permitted use within this area. • TMC 18.44.070.C.3. Height restrictions - The project does not exceed the maximum height limitation of 15 feet in within the River Buffer area or 45 outside the river buffer but within the shoreline jurisdiction. The maximum height of the fuselage or main body of the B-52 plane, when mounted, is anticipated to be 17 feet 11 inches above grade. The top of the vertical tail fin is anticipated to be 42 feet 1 inch above grade. The project structures will not block the views of the river for any residents. • TMC 18.44.070.C.4 Lighting — Two lighting fixtures mounted on 25 foot -tall poles will illuminate the site and be designed to limit spillover and glare on the property to the south where Slip 6 of the Duwamish River is located. Three uplights will illuminate the statue and flag pole base. Additional illumination of the pathways internal to the site is not provided, as the site is not intended to be used after dark or after Museum operating hours. C. Surface Water and Water Quality - TMC 18.44.070.D The project meets the requirements of this section, including incorporating low impact development techniques such as a rain garden and permeable pavement for the pedestrian pathways, and significant amounts of landscaping. D. Archaeological, Cultural and Historic Resources - TMC 18.44. 070.G A Cultural Resource Assessment was prepared for the project site prior to construction of the project and shared with the WA Department of Archaeology and Historic Preservation (DAHP). See Attachments 6 and 8 for their comment letters. The project will be conditioned to ensure the provisions of TMC 18.44.070.G are met. See Section 6 — Public Comments below for more discussion. 8 Shoreline Substantial Development July 19, 2018 E. Environmental Impact Mitigation - TMC 18.44.070.H All shoreline development and uses will occur in a manner that results in no net loss of shoreline ecological functions through the careful location and design of all allowed development and uses. An Environmental Checklist was submitted for the B-52 Memorial Park Phase 1 and 2 (E16-0001) and a Notice of Decision was issued approving the proposal as a Planned Action on March 10, 2016. a. Avoiding the impact altogether by not taking a certain action or parts of an action. The project site is not adjacent to the Green River. The site is separated from Slip 6 on the Green River by approximately 25 feet of property owned by Boeing. The project avoids construction on the riverbank and underwater. b. Minimizing impacts by limiting the degree or magnitude of the action and its implementation by using appropriate technology or by taking affirmative steps to avoid or reduce impacts. • 13 trees will be removed on -site due to disease and site layout constrictions, and per TMC 18.44.080.B, 80 replacement trees are required. A minimum of 23 trees will be planted on site by the applicant and payment into the City's tree fund is allowed for up to 57 of the replacement trees. A tree adjacent to the site will be retained and protected during construction. • Low Impact Developments (LID), including a rain garden and pathways of permeable pavement will be incorporated in the proposed project to address runoff. • Landscaping, including native vegetation, will replace the former paving and compacted soil and gravel surfacing. • All pollution -generating impervious surface area within the site disturbance area was removed as part of previous work on the site in 2016. • Park lighting will be directed away from the river to prevent spillover. c. Rectifying the impact by repairing, rehabilitating, or restoring the affected environment. d. Reducing or eliminating the impact over time by preservation and maintenance operations. e. Compensating for the impact by replacing, enhancing, or providing substitute resources or environments. f. Monitoring the impact and the compensation projects and taking appropriate corrective measures. Impacts to vegetation in the shoreline jurisdiction will be addressed by increasing the amount of trees on the site. A Shoreline Tree Removal and Vegetation Clearing permit to remove 13 existing trees within the shoreline environment was approved on July 17, 2018. Per TMC 18.44.080.B, 80 replacement trees are required, which was determined based on the number and size of trees removed. The applicant will plant a minimum of 23 of the required replacement trees on site. The applicant will also pay a fee in lieu into the City's tree replacement fund for each of the remaining 57 trees which are not able to be planted on site due to King County easement restrictions and the design intent and the operational requirements of the project. An existing tree located close to the park on the 9 Shoreline Substantial Develop-~~t July 19, 2018 adjacent parcel to the south will be retained and its critical root zone protected during construction. F. Signs - TMC 18.44. 070.L Signs within the shoreline jurisdiction will be limited to interpretive signs. G. Vegetation Protection and Landscaping - TMC 18.44.080 A total of 13 trees will be removed within the shoreline jurisdiction along the southern border of the proposed B-52 Bomber Memorial Park site when this project is implemented. The subject trees include 11 Lombardi poplars and two native Bitter cherries, ranging from 25 feet to 85 feet in height and 8 to 26 inches in diameter at 4.5 feet from the ground. Three trees were previously topped at 35 feet, and two trees are diseased and considered not viable. Per TMC 18.44.080.B, 80 native trees are required as replacement, which was determined based on the number and size of trees removed. The applicant is proposing planting 23 of the required replacement trees on site and paying a fee in lieu into the City's tree replacement fund for each of the remaining 57 trees. A number of alternatives were considered to increase the proposed number of replacement trees planted on site, including adding trees to the eastern portion of the site, screening the B.E.A.R.S. trailers on the south side of the property, adding trees in large planters along the King County stormwater easement that could be moved, if needed, and planting trees off -site adjacent to Slip 6. The applicant believed placing more trees on the site was not feasible due to the following reasons: • Planting more trees on the eastern border of the site conflicted with project goals of maintaining visibility of the military branch flags, sculpture, and the aircraft from surrounding vantage points. • Operational requirements of the site, including King County's requirement to keep access to a storm drain manhole along the western portion of the site free of trees. • At the south side of the project site, the Museum of Flight has long accommodated the ongoing operations and activities of the Boeing Employees Amateur Radio Society (B.E.A.R.S.). The trailers here house sensitive communication antennae and equipment, and provide emergency communication services for Boeing and the local public service communities. Existing trees are being removed from this area in order to limit the potential for damage or interference with B.E.A.R.S. operations. • Trees in planters have a low survival rate and have limited mobility. • Given the known soil conditions on the project site, it is speculated that adjacent properties may likely contain contamination, unstable soils, or invasive existing plantings, suggesting that a more intrusive soils investigation, tree survey, and planting study could ensue. The Boeing parcels adjacent to the project site and to Slip 6 (King County Parcel Nos. 562420-1038 and 562420-1032) are further understood to be high - security facilities, and the applicant believes coordination of existing conditions investigations and tree plantings at Slip 6 to be operationally prohibitive. 10 Shoreline Substantial Development July 19, 2018 • • On -site trees to be removed The 23 replacement trees to be planted on -site include a native mix of Western Red Cedar, Cascara, Shore Pine, and Oregon Ash. An existing tree located close to the park on the adjacent parcel to the south will be retained and its critical root zone protected during construction per TMC 18.54.070.1-11. Tree removal and replacement was approved in a Notice of Decision issued on July 17, 2018. Landscape maintenance will occur as needed for successful establishment of the plantings. The applicant will need to submit annual photos of all 23 trees to the City's Urban Environmentalist to ensure proper maintenance and a 100% survival rate for three years following the initial landscape inspection. Per TMC 18.44.080.B.5, the property owner is required to ensure the viability and long-term health of trees planted for replacement through proper care and maintenance for the life of the project. Replaced trees that do not survive must be replanted in the next appropriate season for planting. H. Public Access - TMC 18.44.100 Public access is not required for this project as the site does not abut the Duwamish River shoreline. However, the B-52 park project is providing nearly an acre of open space with a loop path and memorial plaza. The plaza will be raised to allow for views to the river. The plaza and paths all meet ADA requirements, and furnishings including benches, handrails, and site lighting are provided. I. Shoreline Design Guidelines - TMC 18.44.110 1. Relationship of Structure to Site. 2. Building Design. These sections of the TMC do not apply as no buildings are being constructed, only the 11 Shoreline Substantial Develop-- " July 19, 2018 support structures for the B-52 aircraft. 3. Design of Public Access. The project is consistent with the public access design guidelines. An attractively designed and welcoming park will provide visual access to the Duwamish River and nearly an acre of open space with a loop trail to view the B-52 plane and the surrounding area. Site landscaping will consist of native vegetation, consistent with TMC 18.44.080. Durable seating is provided via a low seating wall around the memorial plaza and four benches of metal and wood. Environmentally friendly porous pavement is used on the pedestrian pathways. 6. PUBLIC COMMENTS Comments were received during the Notice of Application period from Gretchen Kaehler of the Washington Department of Archaeology and Historic Preservation on May 24, 2018 (see Attachment 6). Ms. Kaehler notified staff that the project area has a high potential to contain archaeological resources due to the site's location on an old Oxbow Bend of the Duwamish River and proximity to four recorded precontact archaeological sites within 1 mile of the project. She requested that a professional archaeological survey of the project area prior to ground disturbance be conducted to ensure that protected resources would not be inadvertently damaged during construction. Response: A Cultural Resource Assessment was conducted in response to comments from DAHP and submitted to the City, DAHP, King County, and the Muckleshoot, Snoqualmie, Suquamish, and Tulalip tribes on June 26, 2018. The assessment included background research using sources such as geotechnical reports, public records, and historic maps and resources to develop a full of the history of land use and archaeological potential in the project area. The conclusions and recommendations of the Cultural Resource Assessment include the following: "Parcel history, geotechnical borings, and nearby monitoring indicate that at least 4 to 7 feet of recent fill, and possibly more, are present in the study area. Groundwater is likely present at around 10 feet, representing a likely lower boundary of occupation or use. Native sediments could be present between 4 and 10 feet below the surface. Archaeological potential, however, is low to moderate. The native ground surface may have been removed by the cleanup, if not by prior industrial activity. However, the presence of historical artifacts at 12 feet below the surface on the adjacent parcel indicates that some potential remains. The footprint of ground disturbance deeper than 4 feet below the surface is limited to the eight auger -cast piles that form the foundation for the two tie - downs for the project. If possible, given construction methods, archaeological monitoring should occur at those locations, to comply with TMC 18.50.110. An archaeological monitoring plan should be developed and provided to DAHP and interested Native American Tribes. An Inadvertent Discovery Plan should also be 12 Shoreline Substantial Development July 19, 2018 developed, to guide actions in the event that archaeological materials are encountered when the monitor is not on site." DAHP staff submitted a follow-up letter dated July 12, 2018 (See Attachment 8) to the City stating they have reviewed the report and concur with the recommendation that ground disturbance for the project be monitored by a professional archaeologist under an archaeological monitoring and inadvertent discovery plan (MDIP) reviewed by DAHP and the Tribes. DAHP also requested that an MDIP be prepared and submitted to DAHP and the Tribes for review prior to ground disturbance and monitoring. The Assessment report's and DAHP recommendations will be included as a condition of approval of this permit. 7. SEPA AND OTHER CITY APPROVALS An Environmental Checklist was submitted for the B-52 Memorial Park proposal (E16-0001) and a Notice of Decision was issued approving the proposal as a SEPA Planned Action on March 10, 2016. A Shoreline Tree Removal and Vegetation Clearing permit (L18-0030) was approved for this project on July 17, 2018. The applicant must obtain a building permit for park structures. 8. RECOMMENDATION Approval of the shoreline substantial development permit with the following condition: 1. Per the conclusions and recommendations of the Cultural Resource Assessment conducted for this project, the following actions are required: a. Develop and distribute an archaeological monitoring plan to DAHP and interested Native American Tribes prior to ground disturbance and monitoring. b. A professional archaeologist who meets the Secretary of the Interior standards for Professional Archaeology shall be on site to monitor excavation and placement of the eight auger -cast piles that form the foundation for the two tie -downs. c. Develop an Inadvertent Discovery Plan to guide actions in the event that archaeological materials are discovered when the monitor is not on site. 13 STATE OF WASHINGTON DEPARTMENT OF ECOLOGY Northwest Regional Office • 3190 160th Ave SE • Bellevue, WA 98008-5452 • 425-649-7000 711 for Washington Relay Service • Persons with a speech disability can call 877-833-6341 August 1, 2018 Elias Gardner SRG Partnership, Inc. 110 Union Street, Suite 300 Seattle, WA 98101 RECEIVED AUG 03 2018 Community Development Re: City of Tukwila Local Permit L18-0031 — Approved SRG Partnership, Inc. — Applicant Approved Shoreline Substantial Development Permit (SDP) #2018-NW-303 Dear Mr. Gardner: On July 31, 2018, we received notice that the City of Tukwila conditionally approved your application for a SDP.

GeoEngineers previously provided geotechnical engineering design services for this project; the results of our design services were presented in our report dated February 5, 2016. The project site is shown relative to surrounding physical features on Figure 1, Vicinity Map and Figure 2, Site Plan. The foundation support for the B-52 was originally designed as a mat foundation. The project team has decided to support the B-52 on piles because of the proximity to a deep storm sewer line. Based on discussions with Robert Baxter of Magnusson Klemencic Associates (MKA) and information provided by MKA, we understand that the foundation will now consist of two piers with each pier supported on four piles. The piles will be subject to axial loads of up to 65 to 70 kips, and lateral loads of 9 to 10 kips. Drilled augercast piles are likely the most economical pile option and will provide the least disturbance to the nearby sewer line. Recommendations for augercast piles are presented in this addendum. PREVIOUS STUDIES GeoEngineers previously drilled two borings at the project site (B-1 and B-2) to depths of 31.5 and 41.5 feet. To evaluate the subsurface conditions at deeper depths, GeoEngineers reviewed the logs of explorations completed as part of previous studies in the vicinity of the project site, including those completed by GeoEngineers for the design of the Aviation Pavilion and the Aviation High School. The location of the explorations completed for these projects closest to the project site are also shown in Figure 2. The cone penetration log and boring log used in evaluating pile capacities are presented in Appendix A, Previous Explorations. • JUN 112018 Community Development Museum of Flight May 15, 2018 Page 2 CONCLUSIONS AND RECOMMENDATIONS We recommend that the B-52 be supported on augercast piles which are 40 feet in length. Piles extending to this depth will mitigate most, but not all, of the possible settlement due to the presence of liquefiable deposits. Earthquake Engineering Regional Seismicity The Puget Sound region is located at the convergent continental boundary known as the Cascadia Subduction Zone (CSZ), which extends from mid -Vancouver Island to Northern California. The CSZ is the zone where the westward advancing North American Plate is overriding the subducting Juan de Fuca Plate. The interaction of these two plates results in three potential seismic source zones: (1) a shallow crustal source zone; (2) the Benioff source zone; and (3) the CSZ interplate source zone. The shallow crustal source zone is used to characterize shallow crustal earthquake activity within the North American Plate at depths ranging from 3 to 19 miles below the ground surface. The Seattle Fault Zone is considered a shallow crustal source zone. The site is located very close to the current geologic interpretation of the southernmost strand of the east -west trending Seattle Fault Zone. The most recent major earthquake on the Seattle Fault Zone is estimated to have occurred about 1,100 years ago. The Benioff source zone is used to characterize intraplate, intraslab or deep subcrustal earthquakes. Benioff source zone earthquakes occur within the subducting Juan de Fuca Plate at depths between 20 and 40 miles. In recent years, three large Benioff source zone earthquakes occurred that resulted in some liquefaction in loose alluvial deposits and significant damage to some structures. The first earthquake, which was centered in the Olympia area, occurred in 1949 and had a magnitude of 7.1. The second earthquake, which was centered between Seattle and Tacoma, occurred in 1965 and had a magnitude of 6.5. The third earthquake, which was located in the Nisqually valley north of Olympia, occurred in 2001 and had a magnitude of 6.8. The CSZ interplate source zone is used to characterize rupture of the convergent boundary between the subducting Juan de Fuca Plate and the overriding North American Plate. The depth of CSZ earthquakes is greater than 40 miles. No earthquakes on the CSZ have been instrumentally recorded; however, through the geologic record and historical records of tsunamis in Japan, it is believed that the most recent CSZ event occurred in 1700. International Building Code Seismic Design Information We recommend the use of the following 2015 International Building Code (IBC) parameters for Site Class, short period spectral response acceleration (Ss), 1-second period spectral response acceleration (Si) and seismic coefficients (FA and Fv) for the project site. It should be noted that while our analyses indicate that potentially liquefiable soils are present at the site, the fundamental period of vibration of the planned structure is anticipated to be less than 0.5 seconds, and as a result, the exception presented in Section 20.3 of ASCE 7-10 applies for determining the site class. If the fundamental period of vibration of the structure is longer than 0.5 seconds, GeoEngineers should be contacted to provide further guidance. GEOENGINEERSg Fite \o 8039-010-03 Museum of Flight May 15, 2018 Page 3 2015 IBC SEISMIC DESIGN PARAMETERS 2015 IBC Parameter Recommended Value Site Class E Short Period Spectral Response Acceleration, Ss (percent g) 151 1-Second Period Spectral Response Acceleration, Si (percent g) 58 Seismic Coefficient, Fa 0.9 Seismic Coefficient, Fv 2.4 Liquefaction Liquefaction is a phenomenon where soils experience a rapid loss of internal strength as pore water pressures increase in response to strong ground shaking. The increased pore water pressure may temporarily meet or exceed soil overburden pressures to produce conditions that allow soil and water to flow, deform or erupt from the ground surface. Ground settlement, lateral spreading and/or sand boils may result from soil liquefaction. Structures, such as buildings, supported on or within liquefied soils may suffer foundation settlement or lateral movement that can be damaging to the buildings. Based on our analyses, the potential exists for liquefaction within zones of the loose to medium dense sand deposits encountered in the borings completed at the site. The evaluation of liquefaction potential depends on numerous site parameters, including soil grain size, soil density, site geometry, static stresses and the design ground acceleration. Typically, the liquefaction potential of a site is evaluated by comparing the cyclic shear stress ratio (the ratio of the cyclic shear stress to the initial effective overburden stress) induced by an earthquake to the cyclic shear stress ratio required to cause liquefaction. The cyclic shear stress ratio required to cause liquefaction was estimated using an empirical procedure developed by R.E. Moss (2003) based on cone penetration test (CPT) results obtained during field explorations. Estimated ground settlement resulting from earthquake - induced liquefaction was analyzed using empirical procedures by Tokimatsu and Seed (1987) that relate settlement to the CPT data. Analysis of the standard penetration test (SPT) data completed at the site and the SPT and CPT data from the Aviation Pavilion and the Aviation High School project indicates that there is a potential for liquefaction in silt and sand layers within the upper alluvial deposits for the design earthquake event. We estimate that the factor of safety is less than 1 during the design -level earthquake for most of the deposits above a depth of about 50 feet, and for isolated layers of sand and silt present at depths of 50 to 65 feet. Liquefaction -induced free -field ground settlement of the potentially liquefiable zones is estimated to be on the order of 6 to 10 inches for a design -level earthquake. The magnitude of liquefaction -induced ground settlement will vary as a function of the characteristics of the earthquake (earthquake magnitude, location, duration and intensity) and the soil and groundwater conditions. Lateral Spreading Lateral spreading involves lateral displacements of large volumes of liquefied soil. Lateral spreading can occur on near -level ground as blocks of surface soils are displaced relative to adjacent blocks. Lateral spreading also occurs as blocks of surface soils are displaced toward a nearby slope or free -face such as the nearby waterfront by movement of the underlying liquefied soil. Slip No. 6 of the Duwamish River GEOENGINEERS� �' e \0 8039 1)10 (J:3 Museum of Flight May 15, 2018 Page 4 waterway to the west of the site represents a free face condition. Slip No. 6 is a rip -rap faced cut slope which extends about 30 feet below the surrounding adjacent grades, based on available bathymetric information. The central portion of the airpark is about 400 feet from the top of the slope forming the slip. The evaluation of lateral spreading at the site was completed during the design of the Aviation Pavilion and the results of our analyses indicate that ground movement during lateral spreading could be greater than 18 inches if spreading were to occur. We understand that the B-52 foundation will not be designed to withstand lateral spreading. Surface Fault Rupture Based on the United States Geological Survey (USGS) maps of active faults in the Puget Sound region, the site is located close to the Seattle Fault zone. As the depth to bedrock in this area is on the order of about 150 to 250 feet, there is some risk for potential surface fault rupture. However, in our opinion, the risk for surface fault rupture at the project site is still relatively low considering the length and width of the Seattle Fault and the uncertainties associated to the fault location. B-52 Foundation Recommendations - Augercast Piles Augercast piles are an economical pile type in the northwest and typically provide the least disturbance to existing operations. Recommendations for 14- and 18-inch-diameter augercast piles are provided below. We recommend that the piles extend 40 feet into the underlying sand deposits. Augercast piles are constructed using a continuous -flight, hollow -stem auger attached to a set of leads supported by a crane. The first step in the pile casting process consists of drilling the auger into the ground to the specified tip elevation of the pile. Grout is then pumped through the hollow stem during steady withdrawal of the auger and replaces the soils withdrawn on the flights of the auger. The final step is to install a steel reinforcing cage and typically a center bar into the column of fresh grout. One benefit of using augercast piles is that the auger provides support for the soils during the pile installation process, thus eliminating the need for temporary casing or drilling fluid. Another benefit is the elimination of vibrations associated with driven piles. Axial Capacity Axial pile capacity in compression is anticipated to be developed from a combination of side frictional resistance and end bearing capacity. Uplift pile capacity will be developed from side frictional resistance in the deposits which are not prone to liquefaction during a seismic event. Based on the explorations completed for the B-52 and the other nearby projects, we recommend that the piles have a minimum length of 40 feet. For augercast piles which have a minimum length of 40 feet, we recommend the following pile capacities be used for design: Allowable Axial Compression Capacity Allowable Axial Uplift Capacity Pile Type and Size (kips) (kips) 14-inch augercast pile 50 20 18-inch augercast pile 70 30 GEOENGINEERS� F.ie \o 8039 )10-03 Museum of Flight May 15, 2018 Page 5 These allowable values do consider a possible loss of a portion of the skin friction if some liquefaction were to occur, but some settlement could still occur if a very large earthquake resulted in liquefaction of most of this upper sand layer. As a result, it is recommended that the allowable pile capacities not be increased by one-third when considering seismic design loads, but may be increased by one-third for other short term loading such as wind. The allowable capacities are based on the strength of the supporting soils and include a factor of safety of 2 for static loading conditions. For seismic loading conditions, we estimate that the factor of safety is greater than approximately 1.25. The capacities apply to single augercast piles. Axial reduction factors for group effects do not need to be applied if the piles are spaced at least three pile diameters on center. The structural characteristics of the shaft materials and structural connections may impose limitations on shaft capacities and should be evaluated by the structural engineer. Lateral Capacity Lateral loads can be resisted by passive soil pressure on the vertical piles and by the passive soil pressures on the pile cap. Because of the potential separation between the pile -supported foundation components and the underlying soil from settlement, base friction along the bottom of the pile cap should not be included in calculations for lateral capacity. We evaluated the lateral capacity of a single 14- and 18—inch-diameter augercast pile using the computer software program LPILE v2013 produced by Ensoft, Inc. Each pile was assumed to be 40 feet long with the top of the pile modeled as a free -head and located at the bottom of the pile cap. Lateral capacities were evaluated for a range of lateral loads for a free -head condition. Lateral capacities were evaluated for both a static condition, assuming no liquefied soil, and a seismic condition where a reduced strength was assumed. The results of our analysis are presented in Figures 3 through 14. These figures present the deflection, moment and shear versus depth for free -head conditions for 14- and 18—inch-diameter augercast piles subjected to a range of lateral loads at the pile cap. Piles spaced closer than eight pile diameters apart will experience group effects that will result in a lower lateral load capacity for trailing rows of piles with respect to leading rows of piles for an equivalent deflection. We recommend that the lateral load capacity for trailing piles in a pile group spaced three pile diameters apart be reduced by a factor of 0.6. Reductions of the lateral load capacity for trailing piles at spacings greater than three pile diameters but less than eight pile diameters apart can be linearly interpolated. We recommend that the passive soil pressure acting on the pile cap be estimated using an equivalent fluid density of 300 pounds per cubic foot (pcf) where the soil adjacent to the foundation consists of structural fill compacted to at least 95 percent of MDD. The structural fill should extend out from the face of the foundation element for a distance at least equal to 2.5 times the height of the element. This passive resistance value includes a factor of safety of 1.5 and assumes a 2.5-foot-deep pile cap and a minimum lateral deflection of 1 inch to fully develop the passive resistance. Deflections that are less than 1 inch will not fully mobilize the passive resistance in the soil. GEOENGINEERS� F•ie\o 8039,1003 Museum of Flight May 15, 2018 Page 6 Pile Settlement We estimate that the post -construction settlement of pile foundations, designed and installed as recommended, will be on the order of 112 inch or less. Maximum differential settlement should be less than about one-half the post -construction settlement. Most of this settlement will occur rapidly as loads are applied. Construction Considerations Augercast concrete piles should be installed to the recommended penetration discussed previously using a continuous -flight, hollow -stem auger. As is common practice, the pile grout is pumped under pressure through the hollow stem as the auger is withdrawn. Reinforcing steel for bending and uplift is placed in the fresh grout column immediately after withdrawal of the auger. An advantage of the augercast pile installation method is that it causes relatively little vibration and variable length piles can easily be installed. We recommend that the augercast piles be installed by a contractor experienced in their placement and using suitable equipment. Grout pumps should be fitted with a volume -measuring device and pressure gauge so that the volume of grout placed in each pile and the pressure head can be easily determined. While grouting, the rate of auger withdrawal should be uniform and controlled such that the volume of grout pumped is equivalent to at least 115 percent of the theoretical hole volume. A minimum grout line pressure of 100 pounds per square inch (psi) and a minimum grout head of 10 feet (depth of auger in ground when grout return is observed) should be maintained. We recommend that there be a waiting period of at least eight hours between installation of piles spaced closer than 8 feet center -to -center in order to avoid disturbance of concrete undergoing curing in a previously cast pile. Obstructions could be encountered during installation such that new pile locations may need to be selected and/or pile capacities may need to be reevaluated. There may be unexpected variations in the depth to and characteristics of the supporting soils. In addition, no direct information regarding the capacity of augercast piles (e.g., driving resistance data) is obtained while this type of pile is being installed. Therefore, it is particularly important that the installation of augercast piles be monitored by GeoEngineers.

We have reviewed the above archaeological overview. We concur with the recommendation that ground disturbance for the project be monitored by a professional archaeologist under an archaeological monitoring and inadvertent discovery plan (MIDP) reviewed by DAHP and the Tribes. We request that an MIDP be prepared and submitted to DAHP the Tribes for review prior to ground disturbance and monitoring. Thank you for the opportunity to review and we look forward to receiving the MIDP for review. Should you have any questions, please feel free to contact me.

Chris Mailander (CMailander(almuseumoffliaht.oral Subject: RE: B52 Memorial Park Date: Wednesday, May 30, 2018 4:36:19 PM Thanks for checking in, Lynn, I'm planning on bringing in the corrections for correction letter #1 for planning and public works and revision #1 for the same tomorrow. The corrections are pretty straight forward and the revision is an owner -initiated change prior to permit issue — eliminating some of the planting along the west fence to provide KC access to a manhole in the SW corner of the site and changing the footing type from spread footing to pile and pile cap. I mentioned these to you a while back. The correction to the shoreline permit is a bit trickier, mostly because of the sequence of correction and owner -generated revision. Correction Letter #1 for the shoreline permit is straightforward; we have a narrative prepared to address the project's consistency with Review Guidelines. Correction letter #2 has to do with the selection of some of the planting proposed for the site- we will make the changes requested but also need to roll in the changes to the planting plan as I've indicated above. I'm proposing to do both with the response to the correction letter. Lastly, regarding the State Historical comments, I've enlisted the help of a firm called Anchor QEA. They have a staff archeologist, Barbara Bundy, who's involvement is proposed as follows: 1. Barbara will attempt to contact Gretchen at DAHP to discuss the project and doing construction monitoring in a case like this. Would be helpful to have information in item 2 first. 2. It would be helpful to have a more typical description of soil materials encountered in boring logs by GeoEngineers. What was provided in the addendum does not appear to contain this information. Normally we can use the more typical boring logs to determine the depth to fill to make our case about doing construction monitoring (eg., native soils are at depths too deep for hand shovel probing). 3. We will put together a scope and fee proposal for initial services to provide a Cultural Resources memorandum, pending discussion with DAHP. This memorandum would be based on using existing information. Given our current understanding of the project and site it would be based on the premise that construction monitoring of auger casting spoils would be the best way to determine if cultural resources are in the project area, given the depths of fill. 4. Subsequent additional work would be needed to perform construction monitoring. This monitoring will not be included in the initial scope of work proposal, pending DAHP review of the item 3 memorandum. I've provided them with the geotechnical information they've requested and she will be contacting Gretchen at DAHP to propose a scope and fee proposal. That's currently in process. You should see me tomorrow with the planning/pw corrections and revisions, and the response to shoreline correction #1. Please advise on the approach we're planning to take on the shoreline/veg permit; it seems reasonable to address the issue comprehensively rather than responding to comments that no longer necessarily apply, to revise them to conform with the latest plan, and then have to correct them again. I hope that you agree.

As a result of our review, our professional opinion is that the project area has a high potential to contain precontact archaeological resources. The project area is on an old Oxbow Bend of the Duwamish River and four recorded precontact archaeological site are located approximately 1 mile from the project area. Please be aware that archaeological sites are protected from knowing disturbance on both public and private lands in Washington States. Both RCW 27.44 and RCW 27.53.060 require that a person obtain a permit from our Department before excavating, removing, or altering Native American human remains or archaeological resources in Washington. Failure to obtain a permit is punishable by civil fines and other penalties under RCW 27.53.095, and by criminal prosecution under RCW 27.53.090. Chapter 27.53.095 RCW allows the Department of Archaeology and Historic Preservation to issue civil penalties for the violation of this statute in an amount up to five thousand dollars, in addition to site restoration costs and investigative costs. Also, these remedies do not prevent concerned tribes from undertaking civil action in state or federal court, or law enforcement agencies from undertaking criminal investigation or prosecution. Chapter 27.44.050 RCW allows the affected Indian Tribe to undertake civil action apart from any criminal prosecution if burials are disturbed. Identification during construction is not a recommended detection method because inadvertent discoveries often result in costly construction delays and damage to the resource. We request a professional archaeological survey of the project area prior to ground disturbance. If archaeological resources are present a permit from DAHP will be required under RCW 27.53. The completed survey should be submitted to DAHP and the interested Tribes for review prior to ground disturbance. DAHP will determine the need for a DAHP permit and additional archaeological work under RCW 27.53 State of Washington • Department of Archaeology & Historic Preservation P.O.

Please see our responses below in red. The design team and the Museum of Flight are committed to working towards resolutions that support the City of Tukwila's shoreline development criteria, and we're happy to have your team's input on this project. Please let me know if you have any questions - I will be available tomorrow and next week (outside of the holiday) to discuss further where necessary, and to provide clarification where needed. Thanks again, ELIAS GARDNER, Assoc. AIA LEED AP D 206 973 1685 0 206 973 1700 SRG PARTNERSHIP, INC srgpartnership.com From: Lynn Miranda Sent: Tuesday, June 26, 2018 12:16 PM To: 'Stan Jaworowski' <siaworow@srgpartnership.com> Subject: B-52 Park Project L18-0030 & L18-0031 Hi Stan, I'm working on the staff report for the Shoreline Tree Removal and the Shoreline Substantial Dev Permits and have a couple of questions and considerations: 1. Looks like the support structures for the plane are about 8' in height above grade. Do you know the maximum height of the plane when mounted? Response: Detail 3/S002 notes a maximum dimension of 4'-0" above grade to support post point of connection. Museum of Flight plans to mount the aircraft no higher than is necessary to transfer weight from the landing gear to the support posts, while also allowing tires to remain in contact with the ground to prevent them from spinning. This anticipated vertical adjustment is in the vicinity of 6 inches. Since the maximum height of aircraft is 41'-7" measured to the top of the vertical tail fin, the maximum height of the final mounted assembly is anticipated to be 42'-1" above grade. Note that the fuselage itself is significantly lower: with mounting adjustment, the maximum height of fuselage is anticipated to be 17'-11" above grade. 2. Our urban environmentalist is concerned about the limited number of replacement trees you're proposing to plant on -site and the large number to be added to the tree replacement fund. The criteria in TMC 18.44.080.6.6. state that "If all required replacement trees cannot be reasonably accommodated on the site, off -site tree replacement within the shoreline jurisdiction may be allowed at a site approved by the City. Priority 1 for off -site tree planting will be at locations within the Transition Zone. If no suitable off -site location is available, the applicant shall pay into a tree replacement fund." Response: The Owner and the design team do not believe planting additional trees on site within the shoreline jurisdiction would be in keeping with the design intents or operational requirements of the Project or of affiliated user groups, for reasons elaborated upon in responses below. Further, the Owner cannot validate a suitable off -site location within the adjacent shoreline jurisdiction, for reasons also elaborated upon in responses below. We understand the need to not plant on King County's easement on the west side of the property. However, we would like to see more trees accommodated on the project site (first priority), or offsite in the shoreline environment (2"d priority). Here are a couple of options for you to consider as you look for appropriate locations for adding more trees: • Adding trees to the east side of the property, between the walkway (around the sculpture) and the parking area. This would also provide shade for park visitors. Response: We have not included trees in the memorial area on the east side of the project site in order to maintain visibility to military branch flags and sculpture at the top of the slope. Locating trees here would also block the view of the aircraft from surrounding vantage points. It has been a primary goal to maintain visibility of the memorial to attract patrons and passersby to venture to this corner of the campus. • Adding trees in large planters along the western side of the park. Would King County accept trees in planters instead of planted in the ground? Trees in planters could also be placed around the plaza area. Response: The design team has advised against trees in planters. These have a low survival rate, and have limited mobility should the Owner or King County need to gain access to this area. • Adding trees behind the trailers on the south side of the property. Response: At the south side of the project site, the Museum of Flight has long accommodated the ongoing operations and activities of the Boeing Employees Amateur Radio Society (B.E.A.R.S.). The trailers here house sensitive communication antennae and equipment, and provide emergency communication services for Boeing and the local public service communities. Existing trees are being removed from this area in order to limit the potential for damage or interference with B.E.A.R.S. operations. • Coordinating with Boeing on planting trees in the Shoreline Jurisdiction, adjacent to Slip 6. Response: Given the known soil conditions on the project site, it is speculated that adjacent properties may likely contain contamination, unstable soils, or invasive existing plantings, suggesting that a more intrusive soils investigation, tree survey, and planting study could ensue. The Boeing parcels adjacent to the project site and to Slip 6 (King County Parcel Nos. 562420-1038 and 562420-1032) are further understood to be high -security facilities, and so we believe coordination of existing conditions investigations and tree plantings at Slip 6 to be operationally prohibitive. 3. The urban environmentalist is concerned with the number of Serviceberry trees planted, as they are prone to disease. Can some of these be replaced with another option? Response: 2 The design team acknowle,.b,..., that rust can affect Serviceberry trees, but. we do not advise against their planting, as rust does not usually affect the overall health of the tree. If the Urban Environmentalist requires that some or all Serviceberry trees be replaced, we would abide to supplant them with another species — please advise required quantity to replace, if necessary. Holodiscus discolor is speculated be a suitable replacement, as it is similar size to Serviceberry. I'm available to discuss comments 2&3 if you'd like. Thought I'd give you my thoughts in writing first. I'm available today until 2pm, then tomorrow from 8-4.

GeoEngineers previously provided geotechnical engineering design services for this project; the results of our design services were presented in our report dated February 5, 2016. The project site is shown relative to surrounding physical features on Figure 1, Vicinity Map and Figure 2, Site Plan. The foundation support for the B-52 was originally designed as a mat foundation. The project team has decided to support the B-52 on piles because of the proximity to a deep storm sewer line. Based on discussions with Robert Baxter of Magnusson Klemencic Associates (MKA) and information provided by MKA, we understand that the foundation will now consist of two piers with each pier supported on four piles. The piles will be subject to axial loads of up to 65 to 70 kips, and lateral loads of 9 to 10 kips. Drilled augercast piles are likely the most economical pile option and will provide the least disturbance to the nearby sewer line. Recommendations for augercast piles are presented in this addendum. PREVIOUS STUDIES GeoEngineers previously drilled two borings at the project site (B-1 and B-2) to depths of 31.5 and 41.5 feet. To evaluate the subsurface conditions at deeper depths, GeoEngineers reviewed the logs of explorations completed as part of previous studies in the vicinity of the project site, including those completed by GeoEngineers for the design of the Aviation Pavilion and the Aviation High School. The location of the explorations completed for these projects closest to the project site are also shown in Figure 2. The cone penetration log and boring log used in evaluating pile capacities are presented in Appendix A, Previous Explorations. RECEIVED JUN 112018 Community Development Museum of Flight May 15, 2018 Page 2 CONCLUSIONS AND RECOMMENDATIONS We recommend that the B-52 be supported on augercast piles which are 40 feet in length. Piles extending to this depth will mitigate most, but not all, of the possible settlement due to the presence of liquefiable deposits. Earthquake Engineering Regional Seismicity The Puget Sound region is located at the convergent continental boundary known as the Cascadia Subduction Zone (CSZ), which extends from mid -Vancouver Island to Northern California. The CSZ is the zone where the westward advancing North American Plate is overriding the subducting Juan de Fuca Plate. The interaction of these two plates results in three potential seismic source zones: (1) a shallow crustal source zone; (2) the Benioff source zone; and (3) the CSZ interplate source zone. The shallow crustal source zone is used to characterize shallow crustal earthquake activity within the North American Plate at depths ranging from 3 to 19 miles below the ground surface. The Seattle Fault Zone is considered a shallow crustal source zone. The site is located very close to the current geologic interpretation of the southernmost strand of the east -west trending Seattle Fault Zone. The most recent major earthquake on the Seattle Fault Zone is estimated to have occurred about 1,100 years ago. The Benioff source zone is used to characterize intraplate, intraslab or deep subcrustal earthquakes. Benioff source zone earthquakes occur within the subducting Juan de Fuca Plate at depths between 20 and 40 miles. In recent years, three large Benioff source zone earthquakes occurred that resulted in some liquefaction in loose alluvial deposits and significant damage to some structures. The first earthquake, which was centered in the Olympia area, occurred in 1949 and had a magnitude of 7.1. The second earthquake, which was centered between Seattle and Tacoma, occurred in 1965 and had a magnitude of 6.5. The third earthquake, which was located in the Nisqually valley north of Olympia, occurred in 2001 and had a magnitude of 6.8. The CSZ interplate source zone is used to characterize rupture of the convergent boundary between the subducting Juan de Fuca Plate and the overriding North American Plate. The depth of CSZ earthquakes is greater than 40 miles. No earthquakes on the CSZ have been instrumentally recorded; however, through the geologic record and historical records of tsunamis in Japan, it is believed that the most recent CSZ event occurred in 1700. International Building Code Seismic Design Information We recommend the use of the following 2015 International Building Code (IBC) parameters for Site Class, short period spectral response acceleration (Ss), 1-second period spectral response acceleration (Si) and seismic coefficients (FA and Fv) for the project site. It should be noted that while our analyses indicate that potentially liquefiable soils are present at the site, the fundamental period of vibration of the planned structure is anticipated to be less than 0.5 seconds, and as a result, the exception presented in Section 20.3 of ASCE 7-10 applies for determining the site class. If the fundamental period of vibration of the structure is longer than 0.5 seconds, GeoEngineers should be contacted to provide further guidance.

The increased pore water pressure may temporarily meet or exceed soil overburden pressures to produce conditions that allow soil and water to flow, deform or erupt from the ground surface. Ground settlement, lateral spreading and/or sand boils may result from soil liquefaction. Structures, such as buildings, supported on or within liquefied soils may suffer foundation settlement or lateral movement that can be damaging to the buildings. Based on our analyses, the potential exists for liquefaction within zones of the loose to medium dense sand deposits encountered in the borings completed at the site. The evaluation of liquefaction potential depends on numerous site parameters, including soil grain size, soil density, site geometry, static stresses and the design ground acceleration. Typically, the liquefaction potential of a site is evaluated by comparing the cyclic shear stress ratio (the ratio of the cyclic shear stress to the initial effective overburden stress) induced by an earthquake to the cyclic shear stress ratio required to cause liquefaction. The cyclic shear stress ratio required to cause liquefaction was estimated using an empirical procedure developed by R.E. Moss (2003) based on cone penetration test (CPT) results obtained during field explorations. Estimated ground settlement resulting from earthquake - induced liquefaction was analyzed using empirical procedures by Tokimatsu and Seed (1987) that relate settlement to the CPT data. Analysis of the standard penetration test (SPT) data completed at the site and the SPT and CPT data from the Aviation Pavilion and the Aviation High School project indicates that there is a potential for liquefaction in silt and sand layers within the upper alluvial deposits for the design earthquake event. We estimate that the factor of safety is less than 1 during the design -level earthquake for most of the deposits above a depth of about 50 feet, and for isolated layers of sand and silt present at depths of 50 to 65 feet. Liquefaction -induced free -field ground settlement of the potentially liquefiable zones is estimated to be on the order of 6 to 10 inches for a design -level earthquake. The magnitude of liquefaction -induced ground settlement will vary as a function of the characteristics of the earthquake (earthquake magnitude, location, duration and intensity) and the soil and groundwater conditions. Lateral Spreading Lateral spreading involves lateral displacements of large volumes of liquefied soil. Lateral spreading can occur on near -level ground as blocks of surface soils are displaced relative to adjacent blocks. Lateral spreading also occurs as blocks of surface soils are displaced toward a nearby slope or free -face such as the nearby waterfront by movement of the underlying liquefied soil. Slip No. 6 of the Duwamish River GEOENGINEERS He \u 8039 )10.03 Museum of Flight May 15, 2018 Page 4 waterway to the west of the site represents a free face condition. Slip No. 6 is a rip -rap faced cut slope which extends about 30 feet below the surrounding adjacent grades, based on available bathymetric information. The central portion of the airpark is about 400 feet from the top of the slope forming the slip. The evaluation of lateral spreading at the site was completed during the design of the Aviation Pavilion and the results of our analyses indicate that ground movement during lateral spreading could be greater than 18 inches if spreading were to occur. We understand that the B-52 foundation will not be designed to withstand lateral spreading. Surface Fault Rupture Based on the United States Geological Survey (USGS) maps of active faults in the Puget Sound region, the site is located close to the Seattle Fault zone. As the depth to bedrock in this area is on the order of about 150 to 250 feet, there is some risk for potential surface fault rupture. However, in our opinion, the risk for surface fault rupture at the project site is still relatively low considering the length and width of the Seattle Fault and the uncertainties associated to the fault location. B-52 Foundation Recommendations - Augercast Piles Augercast piles are an economical pile type in the northwest and typically provide the least disturbance to existing operations. Recommendations for 14- and 18-inch-diameter augercast piles are provided below. We recommend that the piles extend 40 feet into the underlying sand deposits. Augercast piles are constructed using a continuous -flight, hollow -stem auger attached to a set of leads supported by a crane. The first step in the pile casting process consists of drilling the auger into the ground to the specified tip elevation of the pile. Grout is then pumped through the hollow stem during steady withdrawal of the auger and replaces the soils withdrawn on the flights of the auger. The final step is to install a steel reinforcing cage and typically a center bar into the column of fresh grout. One benefit of using augercast piles is that the auger provides support for the soils during the pile installation process, thus eliminating the need for temporary casing or drilling fluid. Another benefit is the elimination of vibrations associated with driven piles. Axial Capacity Axial pile capacity in compression is anticipated to be developed from a combination of side frictional resistance and end bearing capacity. Uplift pile capacity will be developed from side frictional resistance in the deposits which are not prone to liquefaction during a seismic event. Based on the explorations completed for the B-52 and the other nearby projects, we recommend that the piles have a minimum length of 40 feet. For augercast piles which have a minimum length of 40 feet, we recommend the following pile capacities be used for design: Allowable Axial Compression Capacity Allowable Axial Uplift Capacity Pile Type and Size (kips) (kips) 14-inch augercast pile 50 20 18-inch augercast pile 70 30 GEOENGINEERS. Fde No. 8039 )10-03 Museum of Flight May 15, 2018 Page 5 These allowable values do consider a possible loss of a portion of the skin friction if some liquefaction were to occur, but some settlement could still occur if a very large earthquake resulted in liquefaction of most of this upper sand layer. As a result, it is recommended that the allowable pile capacities not be increased by one-third when considering seismic design loads, but may be increased by one-third for other short term loading such as wind. The allowable capacities are based on the strength of the supporting soils and include a factor of safety of 2 for static loading conditions. For seismic loading conditions, we estimate that the factor of safety is greater than approximately 1.25. The capacities apply to single augercast piles. Axial reduction factors for group effects do not need to be applied if the piles are spaced at least three pile diameters on center. The structural characteristics of the shaft materials and structural connections may impose limitations on shaft capacities and should be evaluated by the structural engineer. Lateral Capacity Lateral loads can be resisted by passive soil pressure on the vertical piles and by the passive soil pressures on the pile cap. Because of the potential separation between the pile -supported foundation components and the underlying soil from settlement, base friction along the bottom of the pile cap should not be included in calculations for lateral capacity. We evaluated the lateral capacity of a single 14- and 18—inch-diameter augercast pile using the computer software program LPILE v2013 produced by Ensoft, Inc. Each pile was assumed to be 40 feet long with the top of the pile modeled as a free -head and located at the bottom of the pile cap. Lateral capacities were evaluated for a range of lateral loads for a free -head condition. Lateral capacities were evaluated for both a static condition, assuming no liquefied soil, and a seismic condition where a reduced strength was assumed. The results of our analysis are presented in Figures 3 through 14. These figures present the deflection, moment and shear versus depth for free -head conditions for 14- and 18—inch-diameter augercast piles subjected to a range of lateral loads at the pile cap. Piles spaced closer than eight pile diameters apart will experience group effects that will result in a lower lateral load capacity for trailing rows of piles with respect to leading rows of piles for an equivalent deflection. We recommend that the lateral load capacity for trailing piles in a pile group spaced three pile diameters apart be reduced by a factor of 0.6. Reductions of the lateral load capacity for trailing piles at spacings greater than three pile diameters but less than eight pile diameters apart can be linearly interpolated. We recommend that the passive soil pressure acting on the pile cap be estimated using an equivalent fluid density of 300 pounds per cubic foot (pcf) where the soil adjacent to the foundation consists of structural fill compacted to at least 95 percent of MDD. The structural fill should extend out from the face of the foundation element for a distance at least equal to 2.5 times the height of the element. This passive resistance value includes a factor of safety of 1.5 and assumes a 2.5-foot-deep pile cap and a minimum lateral deflection of 1 inch to fully develop the passive resistance. Deflections that are less than 1 inch will not fully mobilize the passive resistance in the soil. GEOENGINEERS —le No 8039 01, 03 Museum of Flight May 15, 2018 Page 6 Pile Settlement We estimate that the post -construction settlement of pile foundations, designed and installed as recommended, will be on the order of 1/2 inch or less. Maximum differential settlement should be less than about one-half the post -construction settlement. Most of this settlement will occur rapidly as loads are applied. Construction Considerations Augercast concrete piles should be installed to the recommended penetration discussed previously using a continuous -flight, hollow -stem auger. As is common practice, the pile grout is pumped under pressure through the hollow stem as the auger is withdrawn. Reinforcing steel for bending and uplift is placed in the fresh grout column immediately after withdrawal of the auger. An advantage of the augercast pile installation method is that it causes relatively little vibration and variable length piles can easily be installed. We recommend that the augercast piles be installed by a contractor experienced in their placement and using suitable equipment. Grout pumps should be fitted with a volume -measuring device and pressure gauge so that the volume of grout placed in each pile and the pressure head can be easily determined. While grouting, the rate of auger withdrawal should be uniform and controlled such that the volume of grout pumped is equivalent to at least 115 percent of the theoretical hole volume. A minimum grout line pressure of 100 pounds per square inch (psi) and a minimum grout head of 10 feet (depth of auger in ground when grout return is observed) should be maintained. We recommend that there be a waiting period of at least eight hours between installation of piles spaced closer than 8 feet center -to -center in order to avoid disturbance of concrete undergoing curing in a previously cast pile. Obstructions could be encountered during installation such that new pile locations may need to be selected and/or pile capacities may need to be reevaluated. There may be unexpected variations in the depth to and characteristics of the supporting soils. In addition, no direct information regarding the capacity of augercast piles (e.g., driving resistance data) is obtained while this type of pile is being installed. Therefore, it is particularly important that the installation of augercast piles be monitored by GeoEngineers.

I understand that you will be resubmitting the landscape plans for the project so please include your responses to the following comment in your next submittal for both permits: Sheets L5.10 and L5.20 - Landscape Planting Plan (North & South) 1. There are several plants listed on the plant schedule that require wetter soil conditions than most likely exist on the site: Crataegus douglasii Malus Fusca Carex obnupta Deschampsia cespitosa Juncus tenuis Some of these plants are located appropriately in the rain garden. Those plants located outside of the rain garden must be replaced with plants that tolerate a dryer condition to ensure their survival. 2. Per TMC 18.44.080.C.1.b and g, native vegetation must be planted within the shoreline jurisdiction. The following plants are not native — please replace: Cistus salviifolius `Prostratus Salvia nemorosa `Cardonna' Allium x Millenium Sesleria autumnalis 1 3. Plant Schedule must include spacing of plants. For plants in the River Buffer, see River Buffer Vegetation Planting Densities Table in TMC 18.44.080.C.2. 4. Plant materials must be consistent with the regulations in TMC 18.52.060.A. 5. Please add the following to the Notes Section on Sheet L5.10: • Pesticides shall not be used in the Shoreline jurisdiction unless approved in writing by the City of Tukwila Urban Environmentalist. • For soil preparation in bioretention areas, existing soils must be protected from compaction. Bioretention soil media must be prepared in accordance with standard specifications of the Surface Water Design Manual. • For all other plantings (such as large planting areas where soil volumes are adequate for healthy root growth), soils must be prepared for planting in accordance with BMP T5.13, "Post Construction Soil Quality and Depth," from the Washington Department of Ecology Stormwater Management Manual for Western Washington. • Prior to planting, a soil inspection by the City of Tukwila's Urban Environmentalist must be scheduled to ensure soils are properly prepared. • Installation of landscape plants must comply with BMPs including: a. Planting holes that are the same depth as the size of the root ball and two to three times wider than the root ball. b. Root balls of potted and balled and burlapped (B&B) plants must be loosened and pruned as necessary to ensure there are no encircling roots prior to planting. All burlap and all straps or wire baskets must be removed from B&B plants prior to planting. c. The top of the root flare, where the roots and the trunk begin, should be placed at grade. The root ball shall not extend above the soil surface and the flare shall not be covered by soil or mulch. d. If using mulch around trees and shrubs, maintain at least a 6-inch mulch -free ring around the base of the tree trunks and woody stems of shrubs. If using mulch around groundcovers until they become established, mulch shall not be placed over the crowns of perennial plants. • Installation of the landscaping shall be completed and a Landscaping Declaration submitted by the owner or owner's agent at the time of the final landscape inspection. Any plant substitutions shall be noted on the Declaration. 6. Delete #3 under Notes on Sheet L5.10, as d. above replaces it. 7. Delete #4 under Notes on Sheet L5.10, as c. above replaces it. 8. Sheet L5.30. Details #3 & #4. Ensure that the specifications listed here do not conflict with the Notes on Sheet L5.10. 2 Sheet C003 1. Under General, please revise # 1 as follows: "At least one week before beginning construction, contact public works utilities inspector and Tukwila's Urban Environmentalist and schedule a preconstruction meeting."

WASHINGTON 98101 206 973 1700 SRG PARTNERSHIPCOM MEMORANDUM MEMO DATE: May 30, 2018 REVISION DATE: Date PROJECT NAME:Museum of Flight B-52 Memorial Park TO: Lynn Miranda, Senior Planner, City of Tukwila SUBJECT: L18-0031 Shoreline Substantial Development for B-52 Memorial Park SRG PROJECT #: 217021 FROM :S Jaworowski, SRG DISTRIBUTION: City of Tukwila: L Miranda; MOF: C Mailander, C Miller; Site Workshop: N Ross ; SRG: A Pleskac, E Gardiner ATTACHMENTS: Shoreline Substantial Correction Letter #1, Revision Submittal Cover Sheet Dear Lynn, Our discussion regarding cited guidelines is as follows: Goal 6.3: Development along the shoreline that fosters the economic vitality of Tukwila while preserving the long-term benefits of the river. Design Team Response: The Museum of Flight 8-52 Park is an extension of the Museum of Flight Air Pavilion, and the greater Museum complex. The MOF draws over half a million visitors per year and employs nearly 200 people. The 8-52 park will add an additional exhibit of a restored B-52G, while maintain visual access to the river and an ecologically restored park area for visitors to enjoy. We believe this use meets the goals of both economic vitality and preserving the benefits of the river. MIC Development Policy 5.3.8: Ensure that non -water dependent shoreline development in the MIC provides for shoreline multiple uses to the extent that site security and the success of industrial operations are not jeopardized; ensures no net loss of shoreline function and provides adequate mitigation for the Toss of shoreline multiple use opportunities. Design Team Response: The 8-52 project site is within the shoreline buffer but is separated from the actual high water line by a 25' strip of land owned by the Boeing Company so that there is no direct access to the river from our site. Shoreline access is controlled by the Boeing Company. We believe that the development of the 8-52 park provides flexibility for future development or shoreline function in Page 1 of 3 7.04 JINN 04 2018 Community Development that it has no permanent structures other than footings for the aircraft in the shoreline buffer area. Policy 6.6: Access and Recreational Use, Comprehensive Plan Goal 5.6 Goal: Increase the amount and diversity of opportunities for public recreation and access to and along the river, including visual and cultural access, access to the water's edge, opportunities for small boat navigation and access, and connections to other neighborhoods, consistent with the shoreline character. Design Team Response: The 8-52 project site is within the shoreline buffer, but is separated from the actual high water line by a 25' strip of land owned by the Boeing Company so that there is no direct access to the river from our site. However, we are creating a park space that will be open to the public with many recreational amenities including a loop path around the aircraft, a memorial plaza located on a raised mound surrounded by lawn, from which one can view to the river. Policy 5.6.14: For MIC properties not included in the King County Green River Trail Plan, require shoreline development to provide public access or a private natural area in lieu of public access, or otherwise mitigate the loss of public access. -Implementation Strategies for Policies 5.6.12-14: - Shoreline design guidelines - Shoreline access guidelines - Walk and Roll Plan - Parks and Open Space Design Team Response: The 8-52 project is providing nearly an acre of open space with a native meadow planting, raingarden, loop path and memorial plaza. Because our site is not directly adjacent to the river and is very flat, views from the southwest corner nearest the high-water line are not very clear. Therefore, we have raised our plaza to allow for views to the river. The plaza and paths all meet ADA requirements, and furnishings including benches, handrails and site lighting are provided. The park plantings are native/ adaptive in accordance with Vegetation Protection And Landscaping section of the Tukwila Shoreline Master Program, and any tree removal is being either replaced or paid for by the Museum in lieu of planting additional trees, based on the restrictions inherent in our program. Policy 5.10.1: Design, locate, and manage shoreline development including streets, flood control projects, surface water drainage and sewer systems, clearing and Page 2 of 3 grading activities, and landscaping in a manner which minimizes opportunities for pollutants to enter the river, provides erosion control and otherwise protects water quality. Design Team Response: Minimal grading is happening on the site. The former compacted gravel parking area was de -compacted and replaced with hydroseeded meadow as part of the first phase of this project (which is complete). Our next phases will enhance that meadow and add additional planting and permeable paving. At the low point of the site where water currently pools, we are adding a rain garden to increase infiltration and filter any pollutants that may be carried with runoff across our site.

My inquiry is based on the following: 1- Part of the project is within the 100' of the Duwamish OHWM but has no waterway frontage. The museum's property does not front the Duwamish, that property is held by another owner and is separated by a fence and is inaccessible from the project site and to the project team. 2- This is phase II of the project and most civil and some landscape action occurred during phase I; this phase is a continuation of that work and further landscape enhancements are shown. 3- There are no buildings within the site and no new utilities will be added. All utility work occurred in phase I. Only landscape improvements occur within 100' of the Duwamish OHWM. Footings that support the aircraft are located between the 100'and 200" marks, and the bottom of the aircraft is elevated off the ground by 3 feet (+/-). 4- Phase I took 40,000 sq feet of compacted gravel paving and replaced it with native vegetation. This phase II will consist of 23,000 sq ft of native flowering meadow planting, 650 sq ft of raingarden planting, and the replacement of 11 non-native poplars and 2 diseased bitter cherry trees with 58 native tree species, including 2 evergreen species. All new paving is permeable. The improvements will provide better soil stabilization, improved runoff water quality, and habitat for local wildlife. 5- There is an associated permit application for Shoreline Tree Removal and Vegetation Clearing that will be submitted simultaneously per the description above. The landscape architect has fit required planting on the site to mitigate trees trimmed/removed. Page 1 of 3 8f4-1 Please consider that the Museum is under a critical deadline as the aircraft to be displayed on the site is currently being disassembled in Everett and is being readied for arrival in May. My planned submittal consists of the following. Please flag/ inform me of any changes I need to make. Checklis Items: A. Will provide VB. 1. Will provide vicinity map 2.

Your permit is to create a permanent exhibit of a B-52 aircraft and a Veteran's Memorial Plaza in park -like section. Revisions are needed to comply with King County requirements relating to a storm drain easement and include relocating the aircraft and park elements to the eastern portion of the site, adding more landscaping, and changing to the under carriage support structures from a deep foundation to a shallow foundation. Your project is within the High Intensity shoreline environment designation of the Duwamish River, a shoreline of statewide significance. By law, local governments must review all SDPs for compliance with: • The Shoreline Management Act (Chapter 90.58 RCW) • Ecology's Substantial Development Permit approval criteria (Chapter 173-27-150 WAC) • The City of Tukwila Local Shoreline Master Program. Local governments, after reviewing SDPs for compliance, are required to submit them to Ecology. Your approved application for a revised SDP was received by Ecology. Other federal, state, and local permits may be required in addition to this shoreline permit. What Happens Next? At your own risk, you may begin your revised project immediately, provided you have all other required permits. However, a 21-day appeal period begins on November 9, 2018, the "date of filing." This waiting period allows anyone (including you) who disagrees with any aspect of this permit to appeal the decision to the state Shorelines Hearings Board. We recommend contacting the Shorelines Hearings Board at (360) 664-9160 before beginning permit activities to ensure that no appeal has been filed. Information on appeals is also posted at The Museum of Flight November 9, 2018 Page 2 of 2 http://www.eluho.wa.gov/Decision/Search Cases. Select "Shorelines Hearings Board" from the drop down menu labeled "Board" and enter "Search." The most current appeal will appear on top. If y want to appeal this decision, you can find appeal instructions (Chapter 461-08 WAC) at the Shorelines Hearings Board website above. They are also posted on the website of the -Washington State Legislature at: http://apps.leg.wa.gov/wac. If you have any questions about this letter, please contact Misty Blair, Senior Shoreline Planner, at (425) 649-7244 or misty.blair@ecy.wa.gov.

The tree fee will also be invoiced after the fact, generally near final permit approval. This is because the planner and urban environmentalist will need to review your landscaping plan and requested tree removal. The $2728.00 is just an estimate, depending on what trees are allowed to be removed and what monitoring may be required (this is all site specific) the cost could be more or less. The only cost due at intake is the $6828.00 The $2728.00 is an estimate that would need to be confirmed via the planner during the permitting process before payment would accepted. Expect to hear from your planner on this before final approval of your tree permit.

The project site is shown relative to surrounding physical features on the Vicinity Map (Figure 1) and the Site Plan (Figure 2). We understand that the Museum of Flight (Museum) is currently planning to permanently display a B-52 bomber west of the covered airpark currently under construction. The site for the B-52 will be immediately south of the Aviation High School parking lot and north of Slip 6. The wheel Toads for the plane are approximately 125 kips in the back and 60 kips in the front. At this time, the project will entail constructing a foundation to support the B-52 bomber and landscaping around the display. At a later date, other landscape features might be added. Our understanding of the project is based on information provided by Nathan Messmer with SRG Architects and discussions with various team members. The purposes of this study were to review existing geotechnical information and to complete additional subsurface explorations at the project site as a basis for providing geotechnical engineering conclusions and recommendations for the design and construction of the B-52 foundation. Our services were completed in general accordance with our proposal dated December 1, 2015. Our specific scope of services for the geotechnical engineering services included: • Reviewing previous explorations completed at the site and on adjacent properties; • Completing additional borings to characterize the subsurface conditions at the site; • Performing analyses to evaluate various foundation support options; • Completing soil nutrient analyses; and • Preparing this geotechnical engineering report. FIELD EXPLORATIONS AND LABORATORY TESTING Field Explorations The subsurface conditions at the site were evaluated by completing two borings (B-1 and B-2) to depths of 31.5 and 41.5 feet. The approximate locations of these explorations are shown in Figure 2. A detailed description of the field exploration program and the logs of the borings are presented in Appendix A. Laboratory Testing Soil samples were obtained during the drilling and taken to GeoEngineers' laboratory for further evaluation. Selected samples were tested for the determination of moisture content, percent fines, gradation characteristics and Atterberg limits (plasticity characteristics). The tests were performed in general accordance with test methods of the American Society for Testing and Materials (ASTM). A description of the laboratory testing and the test results are presented in Appendix B. GEOENGINEERS_,0 February 5, 2016: Page 1 File No. 8039-010-02 Additional Soil Characteristics The landscape architect for the project requested that the surficial soils at the site be tested for total metals and certain minerals and other plant nutrient characteristics. Composite soil samples were obtained by obtaining a soil sample from the upper 12 inches at three locations across the east and west half of the site. The samples from the three locations were mixed to develop two composite samples, one for the east half and the other for the west half. Composite 1 represents the west portion of the site and Composite 2 the eastern portion. OnSite Environmental tested the composite samples for total metals. AgSource Laboratories in Umatilla, Oregon tested the samples for nutrients and texture. The results of the soil tests are presented in Appendix C. PREVIOUS STUDIES GeoEngineers reviewed the logs of explorations completed as part of previous studies in the vicinity of the project site, including those completed by GeoEngineers for the design of the Covered Airpark and the Aviation High School. The location of the borings completed for the Aviation High School project closest to the project site are also shown in Figure 2. The boring logs from the borings shown on the Site Plan are presented in Appendix D. SITE CONDITIONS Setting and Site History The project site is located in the Duwamish Valley west of the Aviation High School and the Covered Airpark (currently under construction) in Tukwila, Washington, as shown in Figure 1. The project site is relatively flat. The south side of the project site is situated about 60 feet from Slip 6 which extends to the east off of the Duwamish River. The proposed plane foundation will be about 120 to 140 feet north and northeast of the slip. The site was originally developed in the 1930s for industrial purposes. The site was originally part of a larger parcel consisting of west and east parcels. The west parcel, abutting the Duwamish River, is where a large chemical processing plant operated. The east portion of the property (the portion of the historical site, now owned by the Museum) was used primarily for offices and lesser industrial facilities. The west and east parcels have been subject to numerous environmental assessments and cleanup actions. GeoEngineers previously completed a Phase I ESA on behalf of the Museum, the results of which are presented in our report for the Museum dated February 28, 2007. The Phase I Environmental Site Assessment (ESA) was completed as part of the Museum's due diligence prior to purchasing the east parcel from Container Properties, the previous property owner. At the time of the Phase I ESA, GeoEngineers concluded that the cleanup action had been successfully completed at the subject property and that no known or suspect environmental conditions were identified for the property with the exception of residual toluene in groundwater (and soil at the base of a remedial excavation) in the southwest portion of the property. These previous environmental cleanup actions consisted of remedial excavation of toluene and metals -contaminated soil across portions of the western half of the property. Additionally, an air sparging/vapor extraction system (AS/VE) is still operating in the southwest corner of the property to remediate toluene -contaminated groundwater remaining in this area of the property. This environmental GEOENGINEERSI February 5, 2016 Page 2 File No. 8039.010-02 action is ongoing under the direction of the Environmental Protection Agency (EPA) and is being conducted by the prior property owner, Container Properties. This remedial effort is unrelated to, and will not affect, the Museum's proposed B-52 display plans. GeoEngineers' Phase•I� SA Is cluded-that-"soil-at-the site,,may contain-residual;concentratio sn of h5Thrdous substances (less than MTCA cleanup levels) that may_req lire special.handling and.disposal.proceduresduring site redevelopment." As a part of past clean-up activities by Container Properties, most of the project area was previously excavated to a depth of about 3 feet to remove contaminated soils. These areas were backfilled with clean fill material, but the report does not comment on the degree of compaction applied to the fill soils placed to restore grades. Site Geology Published geologic information for the project vicinity includes a United States Geological Survey Map titled "Geologic Map of Surficial Deposits in the Seattle 30' x 60' Quadrangle, Washington" (Yount et al., 1993) and "The Geologic Map of Seattle - A Progress Report" (Troost et al., 2005). The surficial soils in the vicinity of the site are mapped as alluvial deposits and modified land. The alluvial deposits generally consist of interbedded layers of soil ranging from clay to sand and gravel. These soils were deposited across the valley by the meandering of the Duwamish River, are as much as 250 feet thick and are poorly consolidated. The modified land in this area is typically dredged fill placed to develop Boeing Field and adjacent industrial areas. Surface Conditions The site is relatively level and consists of exposed soil across much of the site and some crushed gravel across other portions of the site. The north and east portions of the site are adjacent to parking areas used for the high school. A 747 and a 737 are currently being stored on the east portion of the site. A fence is present along the south and west boundaries of the site. A large 27-inch-diameter King County storm sewer is present diagonally across the site. Based on existing information, it appears that the invert for this storm drain is about 12 to 13 feet below existing grade. Subsurface Conditions Soil Conditions Based on the borings completed near the proposed foundation pads for the B-52, the soils within 30 feet of the surface consist mainly of surficial fill overlying mainly granular alluvial deposits. The fill consists of loose to medium dense silty sand with some gravel to stiff sandy silt and appears to be about 4 to 5 feet in thick. The fill is underlain by granular alluvial deposits consisting of loose to medium dense sand to silty sand with occasional interbedded layers of silt and sandy silt. A thin (2-to 3-foot-thick) layer of medium stiff silt was encountered within the sand deposits. This upper layer of silt was thicker (5 to 7 feet) in the borings completed for the high school. A clean sand deposit was encountered at a depth ranging from about 11 to 14 feet. At a depth of about 24 feet, the alluvium transitions back to interbedded silty sand and sandy silt deposits. Based on our explorations completed for Aviation High School and the Covered Airpark, we anticipate that below a depth of about 30 to 40 feet, the silt layers are thicker and more numerous. At a depth of about 60 to 65 feet, the upper interbedded granular and fine-grained alluvial deposits are underlain by deposits of soft silt and clay with varying amounts of silt and organic matter (lacustrine fine- grained soils). The soft lacustrine fine-grained soil deposits are underlain by medium dense to very dense GEOENGINEERSI February 5, 2016 Page 3 File No. 8039 010 02 sand and gravel deposits which contain some shell fragments, suggesting that they were deposited in an estuarine environment. Groundwater Conditions Groundwater was generally encountered during drilling at depths ranging from 7 to 9 feet below the ground surface. Based on observations during construction of the high school and the Covered Airpark, we anticipate that the groundwater is typically at a depth of 9 to 12 feet except during extreme high tide events or prolonged periods of precipitation. Groundwater conditions should be expected to fluctuate as a function ,of season, precipitation, and tidal fluctuations of the Duwamish River and other factors. CONCLUSIONS AND RECOMMENDATIONS Based on the results of our subsurface explorations and our geotechnical engineering evaluations, it is our opinion that the foundation for the B-52 bomber can be supported on shallow spread foundations as currently planned. We estimate that the foundations might experience 1 to 2 inches of settlement, but understand that the display can tolerate this amount of settlement. We understand that the Museum and project team are aware that the site is underlain by thick granular deposits which are susceptible to liquefaction during a large earthquake. Therefore, if a large earthquake event occurred, additional settlement or lateral spreading into Slip 6 could impact the foundations; we understand that the Museum is willing to accept this risk. The foundations will be close to the existing King County Storm drain. However, as the invert of the storm drain is 12 to 13 feet below existing grade, in our opinion the loads from the plane will have minimal impacts on the storm drain. The upper fill soils contain sufficient fines that they will become soft and easily disturbed if wet. To minimize disturbance of the near -surface soils and allow for amending these soils for landscaping purposes, we recommend that the earthwork and grading be accomplished during the dryer months of the year. It will be difficult to reuse excavated on -site soil during wet weather. We previously prepared a soil handling plan for the Museum's use during construction for the Covered Airpark. For this project, we have recommended to the Museum and project team members that it should be a goal to keep soil on the property. Although this portion of the Museum's property has been remediated, the soil likely still contains chemicals that, although not a regulatory condition, would need to be tested and handled appropriately if taken off site. B-52 Foundation Support We recommend that the shallow foundations used to support the B-52 bomber be founded on a zone of properly compacted structural fill to provide more uniform support near the base of the foundation. We recommend that the foundations be founded on a layer of structural fill or crushed rock with a minimum thickness of 18 inches. The structural fill/crushed rock should be compacted to at least 95 percent of the maximum dry density (MDD) in general accordance with ASTM International (ASTM) D 1557. If sand is exposed at the base of the excavation, we recommend the exposed surface be recompacted. If silt is exposed along the base of the excavation, we recommend that a woven geotextile fabric such as Mirafi 500X be placed between the exposed soil and the new structural fill. The fabric will aid as a GEOENGINEERSr February 5, 2016 Page 4 File No. 8039.010-02 separation layer between the silt soil and the structural fill. The zone of structural fill should extend laterally beyond the footing edges a horizontal distance at least equal to the thickness of the fill where possible. All loose or disturbed soil must be removed prior to placing the structural fill pad. An allowable soil bearing value of 1,500 pounds per square foot (psf) may be used for support of the plane foundations supported on a zone of structural fill as described above. The allowable soil bearing value applies to the total of dead and long-term live loads and may be increased by up to one-third for wind or seismic loads. For this recommended bearing pressure, we anticipate that the footings will likely be about 7 to 10 feet in width and length to support the plane loads. We estimate that a new isolated footing subjected to a long-term dead load of 1,500 psf for a footing 10 feet square could experience between 1/2 and 1.5 inches of settlement. As discussed above, we understand that the owner recognizes that this type of foundation is susceptible to additional settlement if an earthquake induces liquefaction in the underlying soils. Lateral Resistance Lateral Toads can be resisted by passive resistance on the sides of the footings and by friction on the base of the footings. Passive resistance should be evaluated using an equivalent fluid density of 350 pcf where footings are surrounded by structural fill compacted to at least 95 percent of MDD, as recommended. The structural fill should extend out at least a distance equal to two and one-half times the depth of the foundation element from its face. A passive pressure of 250 pcf should be used if the footing is poured directly against existing fill or native soils. These values also assume the ground surface in front of the footing will be level for a horizontal distance equal to at least two times the depth of the footing. If soils adjacent to footings are disturbed during construction, the disturbed soils must be recompacted, otherwise the lateral passive resistance value must be reduced. Resistance to passive pressure should be calculated from the bottom of adjacent paving or below a depth of 1 foot where the adjacent area is unpaved, as appropriate. Frictional resistance can be evaluated using 0.45 for the coefficient of base friction against footings which are underlain by structural fill. The above values incorporate a factor of safety of about 1.5. Earthwork and Structural Fill Excavation Considerations The near -surface soils encountered in the explorations typically consist of sand with variable amounts of silt, and silt. We anticipate that these soils can be excavated with conventional excavation equipment such as backhoes, trackhoes and dozers. We anticipate that most excavations required for the project will be relatively shallow, on the order of 2 to 4 feet in depth. At this time, we do not anticipate the need for shoring other than possibly the use of trench boxes or trench shields for utility trenches, which is discussed in the "Utility Considerations" section of this report. We anticipate that the depth of the excavations required for the foundations will generally be above the anticipated water level. Perched groundwater may be encountered above this depth if work takes place during or immediately after extended wet weather. We anticipate that the perched water can be handled during construction by sump pumping, as necessary. All collected water should be routed to suitable discharge points. GEOENGINEERSI February 5, 20161 Page 5 File No. 8039-010-02 Temporary Cut Slopes All temporary cut slopes and shoring must comply with the provisions of Title 296 Washington Administrative Code (WAC), Part N, "Excavation, Trenching and Shoring." The contractor performing the work has the primary responsibility for protection of workers and adjacent improvements. We recommend temporary cut slope inclinations of 11H:1V (horizontal to vertical) in the existing fill and alluvial deposits encountered at the site. Some caving/sloughing of the cut slopes may occur at this inclination. The inclination may need to be flattened by the contractor if significant caving/sloughing occurs. These cut slope recommendations apply to fully dewatered conditions. For open cuts at the site, we recommend that: • No traffic, construction equipment, stockpiles or building supplies be allowed at the top of the cut slopes within a distance of at least 5 feet from the top of the cut. • Exposed soil along the slope be protected from surface erosion using waterproof tarps or plastic sheeting. • Construction activities be scheduled so that the length of time the temporary cut is left open is reduced to the extent practicable. • Erosion control measures be implemented as appropriate such that runoff from the site is reduced to the extent practicable. • Surface water be diverted away from the excavation. • The general condition of the slopes be observed periodically by GeoEngineers to confirm adequate stability. Because the contractor has control of the construction operations, the contractor should be made responsible for the stability of cut slopes, as well as the safety of the excavations. The contractor should take all necessary steps to ensure the safety of the workers near slopes. Subgrade Preparation The on -site soils below the existing pavement contain a significant amount of fines (silt) and are moisture - sensitive. Operation of equipment on these exposed soils will be difficult under wet conditions. Disturbance of shallow subgrade soils should be expected if subgrade preparation work is done during periods of wet weather. We anticipate that either existing sand fill or native silt and sand will be exposed across the excavation. If sand or granular fill is exposed, we recommend recompacting the exposed footing subgrade to a dense and unyielding condition. If silt is exposed, as discussed above we recommend that a woven geotextile be placed across the subgrade after all loose soil removed. We anticipate that the depth of the excavation required for the foundation will generally be above the water table. Perched groundwater may be encountered if work takes place during or immediately after extended wet weather. We anticipate that the perched water can be handled during construction by sump pumping, as necessary. All collected water should be routed to suitable discharge points. GEOENGINEERS� February 5, 2016 Page 6 File No. 8039.010-02 Structural Fill We understand the Museum desires to limit the amount of soil exported from the site. The on -site soils in the upper 5 feet typically consist of fine to medium sand with a high percentage of silt. Thus, the on -site sand may be considered for use as structural fill only for placement during periods of dry weather. This will likely not be practicable unless site work is completed during the normally dry summer months (July through September. Even if reused in landscape areas, the fill will be difficult to place and compact during wet weather. The following sections of this report present options for structural fill placement that will be dictated by the weather conditions. On -site Soils The surficial on -site near -surface soils are anticipated to consist of mainly silty fine to medium sand with gravel with some areas of sandy silt. In general, most of the on -site sand is anticipated to contain sufficient fines as to be moisture -sensitive and thus will be difficult to reuse as structural fill unless protected from rain during storage and placed and compacted during extended periods of dry weather. The silt should only be reused in landscape areas. Wet Weather Conditions If construction is planned for the wet winter months, we recommend that imported structural fill be included for construction of the foundation pads. Materials Materials used to support foundations, structures, roadways and parking areas are classified as structural fill for the purpose of this report. Structural fill material quality varies depending upon its use, as described below: • Structural fill to support the plane foundations should meet the criteria for common borrow as described in Section 9-03.14(3) of the 2014 Washington State Department of Transportation (WSDOT) Standard Specifications. Common borrow will be suitable for use as structural fill during dry weather conditions only. If structural fill is placed during wet weather, the structural fill should consist of gravel borrow as described in Section 9-03.14(1) of the WSDOT Standard Specifications, with the additional restriction that the fines content by limited to no more than 5 percent. Alternatively, the structural fill can consist of recycled concrete or crushed rock base course in conformance with Section 9-03.9(3) of the WSDOT Standard Specifications. • Structural fill placed as crushed surfacing base course below sidewalks and pavements should meet the requirements of crushed rock base course in conformance with Section 9-03.9(3) of the WSDOT Standard Specifications. Fill Placement and Compaction Criteria Structural fill should be mechanically compacted to a firm, non -yielding condition. Structural fill should be placed in loose lifts not exceeding 8 to 10 inches in thickness. Each lift should be conditioned to the proper moisture content and compacted to the specified density before placing subsequent lifts. Structural fill should be compacted to the following criteria: • Structural fill placed below foundations should be compacted to 95 percent of the MDD estimated in general accordance with ASTM D 1557. GEOENGINEERSj February 5, 2016 , Page 7 File No. 8039-010-02 • Structural fill placed in pavement or sidewalk areas, including utility trench backfill, should be compacted to 90 percent of the MDD estimated in general accordance with ASTM D 1557, except that the upper 2 feet of fill below final subgrade should be compacted to 95 percent of the MDD. • Structural fill placed as crushed rock base course below pavements should be compacted to 95 percent of the MDD estimated in general accordance with ASTM D 1557. • Nonstructural fill, such as fill placed in landscape areas, should be compacted to at least 85 percent of the MDD estimated in general accordance with ASTM D 1557. In areas intended for future development, a higher degree of compaction should be considered to reduce the settlement potential of the fill soils. We recommend that a representative from our firm be present during placement of structural fill. Our representative will evaluate the adequacy of the subgrade soils and identify areas needing further work, perform in -place moisture -density tests in the fill to evaluate if the work is being done in accordance with the compaction specifications, and advise on any modifications to procedure that may be appropriate for the prevailing conditions. Erosion and Sedimentation Control Potential sources or causes of erosion and sedimentation depend upon construction methods, slope length and gradient, amount of soil exposed and/or disturbed, soil type, construction sequencing and weather. Implementing an erosion and sedimentation control plan will reduce the project impact on erosion -prone areas. The plan should be designed in accordance with applicable city, county and/or state standards. The plan should incorporate basic planning principles, including: • Scheduling grading and construction to reduce soil exposure; ■ Retaining existing asphalt whenever feasible; • Revegetating or mulching denuded areas; • Directing runoff away from denuded areas; • Reducing the length and steepness of slopes with exposed soils; • Decreasing runoff velocities; • Preparing drainage ways and outlets to handle concentrated or increased runoff; ■ Confining sediment to the project site; and • Inspecting and maintaining control measures frequently. In addition, we recommend that sloped surfaces in exposed or disturbed soil be restored so that surface runoff does not become channeled. Some sloughing and raveling of slopes with exposed or disturbed soil should be expected. Temporary erosion protection should be used and maintained in areas with exposed or disturbed soils to help reduce erosion and reduce transport of sediment to adjacent areas and receiving waters. Permanent erosion protection should be provided by paving or landscape planting. GEOENGINEERS_O February 5, 2016 Page 8 File No. 8039.010.02 Until the permanent erosion protection is established and the site is stabilized, site monitoring should be performed by qualified personnel to evaluate the effectiveness of the erosion control measures and to repair and/or modify them as appropriate. Provisions for modifications to the erosion control system based on monitoring observations should be included in the erosion and sedimentation control plan. Utility Considerations Shoring We anticipate that trench excavations required to install utilities and sewers will range from about 3 to 6 feet in depth. All temporary cut slopes and shoring must comply with the provisions of Title 296 WAC, Part N, "Excavation, Trenching and Shoring." The contractor performing the work has the primary responsibility for the protection of workers and adjacent improvements. Temporary shoring will be necessary to support excavations where space limitations restrict the use of open cuts. It may be desirable to excavate partially sloping cuts and use a trench box or other shoring for the lower few feet of the trench. Temporary trench shoring using internal bracing can be designed using active soil pressures. We recommend that temporary shoring be designed using a lateral pressure equal to an equivalent fluid density of 35 pcf for conditions with horizontal backfill adjacent to the excavation. These lateral soil pressures do not include traffic, structure or construction surcharges that should be added separately, if appropriate. Shoring should be designed for a traffic influence equal to a uniform lateral pressure of 100 psf acting over the depth of the trench. More conservative pressure values should be used if the designer deems them appropriate. These soil pressure recommendations are predicated upon the construction being essentially dewatered; therefore, hydrostatic water pressures are not included. If portions of the shoring use passive elements such as anchor or reaction blocks, available soil resistance can be estimated using passive soil pressures assuming an equivalent fluid density of 275 pcf above the water table and 130 pcf below the water table. The above -recommended lateral soil pressures do not include the effects of hydrostatic pressures or surcharges behind the wall. The effects of surcharge loads behind the shoring should be considered in design. If effective dewatering methods are used to lower the groundwater level below the bottom of the excavation, hydrostatic pressures need not be added to the soil pressures within the exposed height of shoring. Dewatering The groundwater across the project area is partially influenced by tidal fluctuations of the Duwamish River. In general, based on our observations during construction of the Space Gallery and the Aviation High School, we anticipate that the groundwater is typically 7 to 10 feet below existing grade. However, the groundwater levels could be higher during extreme high tides or during extended periods of heavy precipitation. Because the soils at the project consist mostly of sand with variable amounts of silt, we recommend that the groundwater table be maintained at least 2 feet below the planned bottom of the excavations during construction. Otherwise, excessive groundwater flow into excavations could cause lateral movement of the granular soils into the excavations, possibly destabilizing the excavations or causing excessive ground settlement adjacent to the excavations. We anticipate that the temporary dewatering system could likely consist of sumps, but other dewatering measures might be necessary GEOENGINEERS February 5, 20161 Page 9 File No. 8039-010-02 depending on the construction sequence and time of year. The contractor should be responsible for the design and installation of the temporary dewatering systems required to complete the project. Pipe Bedding Pipeline bedding material should be placed and compacted on the trench subgrade or foundation material until a layer that is a minimum of 6 inches thick or one-fourth of the outside pipe diameter, whichever is greater, is achieved. Where soft or loose soils are encountered below the pipe alignment, we recommend they be removed to a depth of 12 inches below the invert, or to firm material as directed by the engineer. The pipe bedding material should conform to the pipe manufacturer's recommendations, the design engineer's recommendations, the 2014 WSDOT Standard Specification 9-03.12(3), Gravel Backfill for Pipe Zone Bedding or equivalent City standards. Precedence in case of a conflict should be with the design engineer. From a geotechnical standpoint, the native soils will not be suitable for bedding materials. If select import fill is used for the backfill, the trench backfill will be more permeable than the surrounding soils and will fill with water over time. In this case, we recommend that all buried structures such as manholes be designed for uplift assuming that water will pond to within 5 feet of the top of the manholes. Trench Backfill After the pipe has been laid in the trench, the embedment material should be uniformly placed in maximum 8-inch-thick loose lifts on each side of the pipe, vibrated or otherwise compacted around the pipe haunches (i.e., at and below the pipe spring line) to the top of the zone. We recommend that trench backfill be compacted as recommended in the "Fill Placement and Compaction Criteria" section of this report. A geotechnical engineer should observe the preparation for, placement, and compaction of structural fill. An adequate number of in -place density tests should be performed in the fill to evaluate if the specified degree of compaction is being achieved. At all times during the placement of the pipeline and placement/compaction of the pipeline embedment material, it is the contractor's responsibility to protect the pipeline from damage (e.g., overstressing or impacting the pipeline with heavy equipment, etc.).

GEOENGINEERSj APPENDIX A Field Explorations APPENDIX A FIELD EXPLORATIONS Subsurface conditions at the site were explored on January 8, 2016 by advancing two borings (B-1 and B-2) at the approximate locations shown on Figure 2. The approximate exploration locations were established in the field by measuring distances from existing site features. The borings were completed to depths ranging from 31.5 to 41.5 feet using mini -track drilling equipment, owned and operated by Geologic Drill of Nine Mile Falls, Washington. The borings were continuously monitored by a geotechnical engineer from our firm who examined and classified the soils encountered, obtained representative soil samples, and observed groundwater conditions. Our representative maintained a detailed log of each boring. Disturbed samples of the representative soil types were obtained using a 2-inch outside diameter standard penetration test (SPT) split -spoon sampler. One soil sample in each boring were obtained with a California sampler with a 3-inch outside diameter as a larger sample. The soils encountered in the test borings were typically sampled at 5-foot vertical intervals with the SPT split -spoon sampler through the full depth of the explorations. SPT sampling was performed using a 2-inch outside -diameter split -spoon sampler driven with a standard 140-pound hammer in accordance with ASTM D 1586, with the exception of where the California sampler was used. During the test, a sample is obtained by driving the sampler 18 inches into the soil with a hammer free -falling 30 inches. The number of blows required for each 6 inches of penetration is recorded. The Standard Penetration Resistance ("N-value") of the soil is calculated as the number of blows required for the final 12 inches of penetration (blows/foot). This resistance, or N-value, provides a measure of the relative density of granular soils and the relative consistency of cohesive soils. If the high penetration resistance encountered in the very dense soils precluded driving the total 18-inch sample interval, the penetration resistance for the partial penetration is entered on logs as follows: if the penetration is greater than 6 inches and Tess than 18 inches, then the number of blows is recorded over the number of inches driven; 30 blows for 6 inches and 50 blows for 3 inches, for instance, would be recorded as 80/9-inch. The blow counts are shown on the boring logs at the respective sample depths. The SPT is a useful quantitative tool from which soil density/consistency was evaluated. Soils encountered in the borings were classified in the field in general accordance with ASTM D 2488, the Standard Practice for Classification of Soils, Visual -Manual Procedure, whichis summarized in Figure A-1. The boring log symbols are also described in Figure A-1, and logs of the borings are provided as Figures A-2 and A-3.

Representative samples were selected for laboratory testing consisting of moisture content testing, percent fines (material passing the U.S. No. 200 sieve), sieve analyses and Atterberg Limits. The tests were performed in general accordance with test methods of the American Society for Testing and Materials (ASTM) or other applicable procedures. Additional soil chemical analytical testing was completed on some of the soil samples to provide a basis for developing general recommendations for soil handling during construction. The results of this testing is provided in a separate report dated September 25, 2014. Moisture Content and Density Testing Moisture contents and/or density tests were completed in general accordance with ASTM D 2216 and D 2937 for representative samples obtained from the explorations. The results of these tests are presented on the exploration logs in Appendix A at the depths at which the samples were obtained. Percent Passing U.S. No. 200 Sieve (%F) Selected samples were "washed" through the No. 200 mesh sieve to estimate the relative percentages of coarse and fine-grained particles in the soil. The percent passing value represents the percentage by weight of the sample finer than the U.S. No. 200 sieve. These tests were conducted to verify field descriptions and to estimate the fines content for analysis purposes. The tests were conducted in accordance with ASTM D 1140, and the results are shown on the exploration logs at the respective sample depths. Sieve Analyses Full sieve analyses were performed on one selected sample in general accordance with ASTM D-422. The wet sieve analysis method was used to determine the percentage of soil greater than the U.S. No. 200 mesh sieve. The results of the sieve analyses were plotted, classified in general accordance with the USCS, and presented in Figure B-1. Atterberg Limits Atterberg limits tests were used to classify the soils as well as to help determine the consolidation characteristics of the soils. The liquid limit and the plastic limit were determined in general accordance with ASTM D 4318. The results of the Atterberg limits testing indicated that the sample tested was non -plastic.

Geotechnical Services Are Performed for Specific Purposes, Persons and Projects This report has been prepared for the exclusive use of the Museum of Flight and other project team members for the Museum's B-52 project in Tukwila, Washington. This report may be made available to prospective contractors for their bidding or estimating purposes, but our report, conclusions and interpretations should not be construed as a warranty of the subsurface conditions. This report is not intended for use by others, and the information contained herein is not applicable to other sites. GeoEngineers structures our services to meet the specific needs of our clients. For example, a geotechnical or geologic study conducted for a civil engineer or architect may not fulfill the needs of a construction contractor or even another civil engineer or architect that are involved in the same project. Because each geotechnical or geologic study is unique, each geotechnical engineering or geologic report is unique, prepared solely for the specific client and project site. Our report is prepared for the exclusive use of our Client. No other party may rely on the product of our services unless we agree in advance to such reliance in writing. This is to provide our firm with reasonable protection against open-ended liability claims by third parties with which there would otherwise be no contractual limits to their actions. Within the limitations of scope, schedule and budget, our services have been executed in accordance with our Agreement with the Client and generally accepted geotechnical practices in this area at the time this report was prepared. This report should not be applied for any purpose or project except the one originally contemplated. A Geotechnical Engineering or Geologic Report Is Based on a Unique Set of Project -Specific Factors This report has been prepared for the Museum of Flight B-52 project in Tukwila, Washington. GeoEngineers considered a number of unique, project -specific factors when establishing the scope of services for this project and report. Unless GeoEngineers specifically indicates otherwise, do not rely on this report if it was: • not prepared for you, ■ not prepared for your project, • not prepared for the specific site explored, or ■ Completed before important project changes were made. For example, changes that can affect the applicability of this report include those that affect: • the function of the proposed structure; • elevation, configuration, location, orientation or weight of the proposed structure; • composition of the design team; or • project ownership. 1 Developed based on material provided by ASFE, Professional Firms Practicing in the Geosciences; www.asfe.org . GEOENGINEERS February 5, 2016 Page E-1 Fie No. 8039.010-02 If important changes are made after the date of this report, GeoEngineers should be given the opportunity to review our interpretations and recommendations and provide written modifications or confirmation, as a ppropriate. Subsurface Conditions Can Change This geotechnical or geologic report is based on conditions that existed at the time the study was performed. The findings and conclusions of this report may be affected by the passage of time, by manmade events such as construction on or adjacent to the site, or by natural events such as floods, earthquakes, slope instability or groundwater fluctuations. Always contact GeoEngineers before applying a report to determine if it remains applicable. Most Geotechnical and Geologic Findings Are Professional Opinions Our interpretations of subsurface conditions are based on field observations from widely spaced sampling locations at the site. Site exploration identifies subsurface conditions only at those points where subsurface tests are conducted or samples are taken. GeoEngineers reviewed field and laboratory data and then applied our professional judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface conditions may differ, sometimes significantly, from those indicated in this report. Our report, conclusions and interpretations should not be construed as a warranty of the subsurface conditions. Geotechnical Engineering Report Recommendations Are Not Final Do not over -rely on the preliminary construction recommendations included in this report. These recommendations are not final, because they were developed principally from GeoEngineers' professional judgment and opinion. GeoEngineers' recommendations can be finalized only by observing actual subsurface conditions revealed during construction. GeoEngineers cannot assume responsibility or liability for this report's recommendations if we do not perform construction observation. Sufficient monitoring, testing and consultation by GeoEngineers should be provided during construction to confirm that the conditions encountered are consistent with those indicated by the explorations, to provide recommendations for design changes should the conditions revealed during the work differ from those anticipated, and to evaluate whether or not earthwork activities are completed in accordance with our recommendations. Retaining GeoEngineers for construction observation for this project is the most effective method of managing the risks associated with unanticipated conditions. A Geotechnical Engineering or Geologic Report Could Be Subject to Misinterpretation Misinterpretation of this report by other design team members can result in costly problems. You could lower that risk by having GeoEngineers confer with appropriate members of the design team after submitting the report. Also retain GeoEngineers to review pertinent elements of the design team's plans and specifications. Contractors can also misinterpret a geotechnical engineering or geologic report. Reduce that risk by having GeoEngineers participate in pre -bid and preconstruction conferences, and by providing construction observation. GEOENGINEERS_rii.. February 5, 2016 , Page E-2 Re No. 8039 010-02 Do Not Redraw the Exploration Logs Geotechnical engineers and geologists prepare final boring and testing logs based upon their interpretation of field logs and laboratory data. To prevent errors or omissions, the logs included in a geotechnical engineering or geologic report should never be redrawn for inclusion in architectural or other design drawings. Only photographic or electronic reproduction is acceptable, but recognize that separating logs from the report can elevate risk. Give Contractors a Complete Report and Guidance Some owners and design professionals believe they can make contractors liable for unanticipated subsurface conditions by limiting what they provide for bid preparation. To help prevent costly problems, give contractors the complete geotechnical engineering or geologic report, but preface it with a clearly written letter of transmittal. In that letter, advise contractors that the report was not prepared for purposes of bid development and that the report's accuracy is limited; encourage them to confer with GeoEngineers and/or to conduct additional study to obtain the specific types of information they need or prefer. A pre -bid conference can also be valuable. Be sure contractors have sufficient time to perform additional study. Only then might an owner be in a position to give contractors the best information available, while requiring them to at least share the financial responsibilities stemming from unanticipated conditions. Further, a contingency for unanticipated conditions should be included in your project budget and schedule. Contractors Are Responsible for Site Safety on Their Own Construction Projects Our geotechnical recommendations are not intended to direct the contractor's procedures, methods, schedule or management of the work site. The contractor is solely responsible for job site safety and for managing construction operations to minimize risks to on -site personnel and to adjacent properties. Read These Provisions Closely Some clients, design professionals and contractors may not recognize that the geoscience practices (geotechnical engineering or geology) are far less exact than other engineering and natural science disciplines. This lack of understanding can create unrealistic expectations that could lead to disappointments, claims and disputes. GeoEngineers includes these explanatory "limitations" provisions in our reports to help reduce such risks. Please confer with GeoEngineers if you are unclear how these "Report Limitations and Guidelines for Use" apply to your project or site. Geotechnical, Geologic and Environmental Reports Should Not Be Interchanged The equipment, techniques and personnel used to perform an environmental study differ significantly from those used to perform a geotechnical or geologic study and vice versa. For that reason, a geotechnical engineering or geologic report does not usually relate any environmental findings, conclusions or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Similarly, environmental reports are not used to address geotechnical or geologic concerns regarding a specific project. GEOENGINEERSQ February 5, 2016 Page E-3 File No. 8039.010.02 Biological Pollutants GeoEngineers' Scope of Work specifically excludes the investigation, detection, prevention or assessment of the presence of Biological Pollutants. Accordingly, this report does not include any interpretations, recommendations, findings, or conclusions regarding the detecting, assessing, preventing or abating of Biological Pollutants and no conclusions or inferences should be drawn regarding Biological Pollutants, as they may relate to this project. The term "Biological Pollutants" includes, but is not limited to, molds, fungi, spores, bacteria, and viruses, and/or any of their byproducts. If Client desires these specialized services, they should be obtained from a consultant who offers services in this specialized field.

The report has been prepared using the 2009 King County Surface Water Design Manual (KCSWDM) as a general guideline for this abbreviated Stormwater Technical Information Report (TIR). In some cases the information requested in the KCSWDM is specific to permitting in King County. Requested information that is directly related to work in King County has been omitted from this TIR. The project is located in the City of Tukwila directly southwest of Raisbeck Aviation High School (9229 East Marginal Way South), north of S 94th Place, in the southwestern -most portion of Parcel Number 572980-0010. See Figure 1-1 for a vicinity map showing the location of the site. The project site is currently owned by the Museum of Flight and was formerly owned by Container Properties. Work on the site will be completed in two phases. Phase 1 of the Park project, completed in Summer 2016, included the reconfiguration of the existing adjacent parking, the removal of asphalt pavement, the development of lawn areas, installation of an irrigation system, a new water service for irrigation, and the installation of a pervious gravel area for picnic tables. No significant grading was done for Phase 1. There have been no further site improvements since the completion of Phase 1. The scope of work for Phase 2 will create a landscaped area of natural vegetation, plantings, gravel pathways, and a raised concrete plaza mound with a commemorative statue and flagpoles. All of these improvements are part of an exhibit for restored B-52 aircraft. The project will also include foundations to support the aircraft, irrigation and lighting and removal of trees. The Phase 1 and 2 work were approved as a Planned Action in March 2016. Because this is a phased development, the land cover prior to the start of the Phase 1 improvements is considered the predeveloped condition for the purposes of this TIR. EXISTING DRAINAGE Prior to the commencement of Phase 1, the site was entirely impervious consisting of asphalt or concrete paving and compacted soil and gravel surfacing. Aerial images dating as far back as 1990 show that this site has been impervious since at least that time. A portion of the site currently drains to an existing on -site conveyance on the on the Raisbeck Aviation • High School property which discharges to the Duwamish River through an existing 36-inch outfall, owned by King County, at the northeast corner of Slip 6. This conveyance system was installed during the construction of Raisbeck Aviation High School. This conveyance system connects to an existing storm drain system that includes the King County outfall on the high school site. This system includes a water quality treatment device (StormFilter), installed by the high school project, that treats the pollution - generating impervious surfaces created by that project. The King County outfall also collects discharge from adjacent properties on the west side of East Marginal Way South as well as a portion of the runoff from the King County International Airport. Stormwater Technical Information Report B-52 Memorial Park Phase 2, Tukwila, Washington 1 MAGNUSSON :1 KLEMENCIC #SSOCIA<<S • The reminder of the site has no collection or conveyance system and discharges as overland flow to the adjacent Container Properties site. The site drainage area, site characteristics, and the existing storm drain conveyance system are shown in Figure 1-2. PROPOSED DRAINAGE The Phase 1 drainage did not modify the existing drainage system and the catchment areas draining to the existing conveyance systems were maintained. No new conveyance systems were installed. Phase 2 will maintain all existing drainage systems and there are no proposed improvements. Overall peak flow rates will be reduced as a result of the reduction in impervious surfaces. SECTION 2: CONDITIONS AND REQUIREMENTS SUMMARY SITE CONDITIONS • The site disturbance within the Phase 2 limits of work is 0.83 acres as shown on Figure 2-1. Areas of Phase 2 were previously disturbed for the Phase 1 work. • The existing pervious and impervious areas, prior to Phase 1, within the Phase 2 limits of work, are 0.06 acres and 0.88 acres respectively. See Figure 2-2. • The proposed pervious and impervious areas, after the completion of the Phase2 work, within the Phase 2 limits of work are 0.66 acres and 0.27 acres respectively. See Figure 2-3. This represents an increase to the pervious area, and corresponding decrease to the impervious area, of 0.61 acres. • Prior to the Phase 1 work, the existing pollution -generating impervious surface area within the site disturbance area was 2,571 square feet. All pollution -generating impervious surface areas within the site disturbance area were removed as part of the Phase 1 work. There are not proposed pollution -generating surfaces proposed for Phase 2. CORE REQUIREMENTS Evaluation of the project with respect to the Core and Special Requirements is outlined below. Core Requirement 1: Discharge at the Natural Location The drainage from the site disturbance area will continue to drain to the existing off -site systems on the Container Properties site and Raisbeck Aviation High School, which eventually discharge to outfalls at the Duwamish River. Core Requirement 2: Off -Site Analysis Not applicable. The proposed development reduces the impervious surface and as a result there is no adverse change to the rate, volume, duration, or location of discharges to and from the site. Stormwater Technical Information Report 2 B-52 Memorial Park Phase 2, Tukwila, Washington MAGNUSSON 1 KLEMENCIC ASSOC:AiES ■ Core Requirement 3: Flow Control Not applicable. The project is within the Duwamish River Basin and discharges via a closed conveyance system, with adequate capacity, to a point below River Mile 6, and is therefore exempt from the flow control requirement. Core Requirement 4: Conveyance System There are no new conveyance systems required for this project. Existing on -site conveyance lines have not been analyzed since there is a decrease to the to the peak flow rate as a result of the decrease in impervious area within the site disturbance area. Core Requirement 5: Temporary Erosion and Sedimentation Control A Temporary Erosion and Sedimentation Control (TESC) plan has been prepared for the project. Core Requirement 6: Maintenance and Operation There is an existing water quality treatment facility on the Raisbeck Aviation High School site. Maintenance and operation of this facility is by the high school. Core Requirement 7: Financial Guarantees and Liability Not applicable. This is a requirement specifically related to work in unincorporated King County. Core Requirement 8: Water Quality There will be no new or replaced pollution -generating impervious surface. Additional water quality treatment beyond what currently exists on the high school site is not required. Pollution -generating impervious surface areas were reduced as a result of the removal of asphalt paved parking areas in Phase 1. There no new pollution -generating surfaces proposed for Phase 2. SPECIAL REQUIREMENTS Special Requirement 1: Other Adopted Area -Specific Requirements Not applicable. Special Requirement 2: Flood Hazard Area Delineation Not applicable. The project site appears on the National Flood Insurance Rate Map, dated May 16, 1995, Community Panel No. 53033C0645F, and is situated in Zone "X," an area determined to be outside the 500-year floodplain. Special Requirement 3: Flood Protection Facilities Not applicable. There are no flood protection facilities on the project site.

TESC Requirement 11: Final Stabilization Final stabilization will be in accordance with the final paving and landscape plans for the project. STORMWATER POLLUTION PREVENTION AND SPILL PLAN DURING CONSTRUCTION Best management practices (BMPs) to prevent pollution from construction activities, in addition to the TESC requirements, shall be implemented during construction. These BMPs are based on the activity sheets in the 2009 King County Stormwater Pollution Prevention Manual. Activity Sheet A-4 — Storage of Soil, Sand, and Other Erodible Materials • Cover and contain the stockpiles of raw materials to prevent stormwater from washing material to surface waters or a storm drainage system. The covers must be in place at all times when the stockpile is not in active use. Do not hose down the contained stockpile area to the storm drainage system. • Stockpiles located away from paved areas or where material will not be washed or tracked to the storm drainage system may not need to be covered unless windy conditions cause airborne particulate that could settle on hard surfaces and subsequently be washed into adjacent surface waters or storm drainage systems. • If the stockpiles are so large that they cannot feasibly be covered and contained, implement erosion control practices at the perimeter and as needed on site to prevent erosion and runoff of the stockpiled material into the storm drainage system or off site. See the King County Surface Water Design Manual, Appendix D (Erosion and Sediment Control Standards). • Required routine maintenance: — Sweep paved storage areas as needed and collect and dispose of loose solid materials. Do not hose down the area to a storm drain or ditch. — Stock cleanup materials, such as brooms, dustpans, and vacuum sweepers near the storage area. Activity Sheet A-11 — Cleaning or Washing of Tools and Equipment • Tool and equipment wash water is considered process water, and must discharge to the sanitary sewer, a holding tank, or a process treatment system, regardless of the washing method used. • You are encouraged to recycle your wash water with an enclosed loop system or use self-contained parts washers. Numerous products are commercially available that recycle and contain wash water and cleaning solvents. Stormwater Technical Information Report j 6 B-52 Memorial Park Phase 2, Tukwila, Washington MAGNUSSON '1 KLEMENCIC ASSOCIATES IN • If you cannot connect discharges to a sanitary sewer, process treatment system, or holding tank, you must contact the Washington State Department of Ecology and go through the Individual Wastewater Discharge permit process. • Lawnmowers may be rinsed with water only on a lawn or similar area as long as the rinsed -off grass clippings will not be washed to the storm drain system or surface waters when it rains. Wash water from oily or similarly contaminated lawn maintenance equipment is not allowed to flow to or discharge to any stormwater system or surface water. Activity Sheet A-20 — Concrete and Asphalt Application • Sweep parking lots, storage areas, and driveways as needed to collect dirt, waste, and debris. Do not hose down the area to the storm drainage system. • Cover and contain all nearby storm drains at the beginning of the workday. Drain covers and other containment devices are commercially available to keep runoff out of the storm drainage system. All solids collected must be disposed of properly at the end of the workday (or more frequently) prior to removing the containment or cover device(s). • Contain and collect the slurry from exposed aggregate washing. Never allow the slurry to get into a storm drain, ditch, roadway shoulder or gutter. Use a storm drain cover, inlet protection, or other containment device, such as a hand —dug, lined sump, to direct and contain slurry. All collected runoff must be disposed of properly. • Do not discharge concrete, slurry, or rinse water into gutters, storm drains, or drainage ditches or onto the paved surface of a roadway or driveway. • Designate an area on site where hand tools will be cleaned and the water collected for disposal. Commercial products and services are also available for concrete, slurry, and rinse water containment and disposal. • Sweep the pouring area at the end of the job or more frequently if needed. Collect loose aggregate chunks and dust. Do not hose down the area to a storm drain. Activity Sheet A-31 — Vehicle and Equipment Parking and Storage • Sweep parking lots, storage areas, and driveways as needed to collect dirt, waste, and debris. Do not hose down the area to the storm drainage system. • If washing/pressure washing of the parking lot occurs, the wash water must be collected and discharged to a sanitary sewer or other treatment system. There are services that will clean parking lots and collect water for off -site disposal. Never drain wash water to the storm drainage system. • Gravel and dirt lots may require additional BMPs to prevent sediment -laden water from leaving the site. Vehicles can track dirt out of parking and storage areas onto public roadways. Basic sediment controls as outlined in Appendix D ("Erosion and Sediment Control Standards") of the King County Surface Water Design Manual must be installed if other BMPs do not adequately control sediment laden water from entering off site storm water conveyance systems or surface water. Wheel wash Stormwater Technical Information Report L 7 B-52 Memorial Park Phase 2, Tukwila, Washington MAGNUSSON ;l KLEMENCIC •J ASSOCIATES O facilities may need to be considered if track -out of mud becomes a problem. See Activity Sheet A- 41, "Wheel Wash and Tire Bath Operations." Activity Sheet A-42 — Potable Water Line Flushing or Tank Maintenance • When flushing water lines, filter water through sediment traps. If super -chlorination or chemical treatment is used as part of flushing, the water must be discharged to the sanitary sewer (with applicable permits) or, if a sanitary sewer is not available, the water must be collected and disposed of appropriately. Water cannot be discharged directly to stormwater systems unless it is treated and water quality standards are met. Discharging treated water to stormwater systems requires approval from the Washington State Department of Ecology. Activity Sheet A-44 — Dust Control and Soil Erosion and Sediment Control for Manufacturing and Other Commercial Operations • Sweep paved areas as needed where dust accumulates from commercial, manufacturing, and industrial operations. Use power vacuum cleaners and sweepers as appropriate to minimize generating airborne dust and for more efficient dust removal. • Regularly clean equipment and vehicles subject to dust accumulation from operations. Never wash down equipment or vehicles to the storm drainage system. • Stabilize or cover areas of exposed or disturbed soil where necessary to prevent soil erosion. See the King County Surface Water Design Manual, Appendix D, Erosion and Sediment Control Standards, for recommended erosion and sediment control practices and standards. • Ensure employees are trained in the proper operating procedures to minimize dust accumulation on the ground.

Marginal Way Facility WAD 00928 2302 Dear Mr. Dupuy: The U.S. Environmental Protection Agency, Region 10 received the East Parcel Corrective Measures Implementation Operations and Maintenance Report, 2016 dated March 2017 (Report). The purpose of the Report is to evaluate the performance of corrective measures to remediate the toluene -impacted groundwater in the East Parcel Corrective Measures Implementation (CMI) project area. The Report surrunarizes the results of the final round of quarterly groundwater monitoring completed in June 2016, and serves as the final CMI report for the East Parcel. In Section 4.0 of the Report, the Respondents request fonnal acknowledgment of completion of the East Parcel CMI. Pursuant to Paragraph 7.1 of the Order, the EPA approves the Report. The EPA also acknowledges that corrective measures for the East Parcel are complete, and this letter serves as the final determination of Corrective Action Complete without Controls for the East Parcel. This determination applies only to the East Parcel; separate work continues on the West Parcel under the Order. In 2006, the Respondents extensively investigated and remediated contamination at the East Parcel and sold the property to the Museum of Flight. The EPA issued a partial determination of Corrective Action Complete without Controls for the East Parcel via a letter on December 20, 2006. The determination covered all portions of the East Parcel except a small area in the southwest corner where toluene was suspected to remain present in groundwater. The EPA presented final decisions regarding corrective action for the East Parcel in the 2006 letter. Corrective actions included source area excavation and removal as the final remedy, and a contingency to address any residual toluene in groundwater if source removal did not prove to be an effective groundwater remedy. If within six months of remedy selection, the Respondents could demonstrate that the concentration of toluene in groundwater was below the final groundwater cleanup level (1.0 ing/L), corrective measures would be deemed complete. However, the Respondents could not meet the requirement and developed a work plan to implement additional corrective measures for groundwater in accordance with the contingent remedy. The EPA approved the CMI work plan in 2007 for the East Parcel groundwater remediation. The initial groundwater remedy consisted of a biosparge and vent well system, which was installed in 2008. Soil vapor initially was treated using granular activated carbon through 2008, then by a soil vapor extraction - internal combustion engine system through 2009. In 2010, the EPA approved shutting down active operation of the biosparge/vent system and continuing to monitor the toluene groundwater concentrations for four post -shutdown sampling events. Because of rebound of toluene groundwater concentrations that exceeded the cleanup level, the Respondents restarted the biosparge system in 2012. The EPA approved shut down of the system in-2015 after several consecutive quarterly sampling events demonstrated that toluene remained below the groundwater cleanup level. After four consecutive post - shutdown sampling events during which toluene was not detected, the Respondents dismantled the system in 2016 upon the EPA's approval. The final sampling event in June 2016 narked the thirteenth consecutive quarter in which toluene levels were below the cleanup level, and the tenth consecutive event in which toluene was not detected above the analytical reporting limit. This final determination of Corrective Action Complete without Controls means that the EPA, under authority of the Order, has determined that remedies for the entirety of the East Parcel have been implemented successfully and no further activities or controls are necessary, and that human health and ecological risks have been appropriately addressed. if you have any questions regarding this letter, please contact Janette Knittel at (206) 553-0483 or knittel.janette@epa.gov, or your legal counsel may contact Jennifer MacDonald at (206) 553-8311 or macdonald.jennifer(i),epa.gov. cc: Mr. Chintan Amin Bayer CropScience Mr. David Blount Landye Bennett Blumstcin LLP Mt.

The project Landscape Architect, Natalie Ross of Site Workshop, has been corresponding with Lynn Miranda regarding planting and tree replacement. A copy of an e-mail string between Natalie and Lynn is attached for your information. Approved and completed, Phase 1 removed 40,000 sf of compacted gravel paving, hazardous materials were remediated, and the site readied for Phase 2. For Phase 2, we will plant 23000 sf of native flowering meadow, install 650 sf of raingarden planting, and replace 11 non-native poplar trees and 2 diseased Bitter cherry trees with 58 native tree species, including 2 evergreen species, none of which makes up more than 20% of the total number of trees. Additionally, our new paving system is permeable. These improvements will provide better soil stabilization, improved runoff water quality, and habitat for local wildlife. The work will commence contingent upon the approval of the Building Permit, Public Works Permit, Shoreline Substantial Development Permit, and the Shoreline Tree Removal and Vegetation Clearing Permit, which we hope to receive in May. The expected completion date is November 2018. A preliminary schedule is attached for your use. The Museum of Flight is planning to exhibit a restored B-52 and create a Vietnam Veterans Memorial on this site. One of their main concerns are a row of poplars on the south edge of the site. Several existing trees are directly in conflict with the proposed B-52 wing location. Other trees close to the plane have caused concern because they represent a windfall hazard to the aircraft with the potential to damage it. Natalie and Lynn have discussed the planting and tree replacement scheme. 80 replacement trees are required; 58 can be accommodated on site. We are requesting to pay into the city's tree replacement fund for the remaining 22 trees, for an amount of $2,728 (to be confirmed by the City). We are eager to make the site a showpiece of ecological restoration and the exhibit as a new jewel in the Museum of Flight's mission of honoring the aircraft and airmen throughout the history of aviation. Please consider and approve of this approach.

I ), F..ttch cxi iini significant tree removed shall be replaced with new tree(). native to the Pacific Non1 west and the number of trees to be replaced will. be based on the diameter of the existing tree as shown below, up to a maximum density of 70 new trees per acre. 2), Tree Replacement Ratios Diameter -of Existing No. of Replacement Tree Removed Trees Required 4 - 4 inches g - 12 i.nchQc 12 • lS inches ,.,. 4 18 - 24 inches 6 >24 inches 8 3) Tree sizes. Replacement tree sizes at planting :hall. be determined on a ease by cast basis, but a netally in watercourses and wetlands and their buf rs, replacement plants may be between l and 5 gallon potted plants. Lame caliper n placenrtent trees, ac specified in the landscape code may be required for steep slope tree replacement. If so, it looks like we would be required to install 43 new trees if we are taking out the existing 11 poplars. I am currently only able to fit about 19 trees in the available buffer area. Is there any flexibility in this code? Would planting a larger caliper tree help to satisfy the requirement?

You do need some diversity depending on how many trees you need to plant. For example, if you have to plant more than 8 trees, according to code, only 40% can be the same species, and so on.... See TMC 18.52.060.A.5. You might also want to look at 18.52.070 regarding soil prep, planting, and irrigation.

Do you have any specific suggestions for trees to replace the poplars we are taking out? Would you like to see multiple species, or would using all 1 species work? Right now we 4 were thinking of using Nyssa sylvatica '1 u f,io Tower', which likes wet soil and has a ....b..tly columnar shape, so we could fit more trees into the site. Let me know your thoughts.

SUBSCRIBED AND SWORN TO BEFORE ME ON THIS NOT res Washington y Commission expires on % ay /0 5' 2 0/9 NO NET LOSS CHECKLIST Please respond to the following questions to evaluate your project's impacts and assist in analyzing whether there will be a net loss to shoreline ecological functions requiring mitigation: 1. Describe the existing condition of the shoreline area and riverbank. For example, what plants and how much vegetation currently exist within the 200 foot shoreline jurisdiction; what is the condition of the shoreline (how steep are the banks, is there any erosion or slope failure, what are the soils like); is there "hard armoring" on the riverbank (for example, concrete or wooden bulkheads, metal sheet piling, rip -rap [rocks or concrete/asphalt blocks]), is there paving or are there any structures within the 200 ft. shoreline jurisdiction; are there any docks, piers, decks or other structures near or over the water; are there any above -ground or below ground utilities; etc.? The project site does not border the Duwamish River and is separated from the shoreline by another property owner. Footings for the aircraft support will be located between the 100' and 200' OHWM. Prior to phase 1 the original B-52 site consisted of approx. 40,000 sf of compacted gravel paving, which was replaced with temporary native seed mix. The site is relatively flat: the greatest elevation change (from SW corner of site to north side of the site) is approximately 2 feet over approx. 200 + feet in distance. Soil conditions are described in detail in the Geotechnical Engineering Report included in this submittal; survey conditions for phase 1 are included in the drawing set. Please note that the Museum has undertaken site clean-up actions over the past decade and it was found to be successfully remediated per the EPA on August 29, 2017 (EPA letter attached). 2. How will your project change the existing condition of the shoreline described above? In our final phase II design, that gravel parking area will be replaced by 23000 sf of native flowering meadow planting, 650 sf of raingarden planting, and the replacement of 11 non-native poplar trees and 2 diseased Bitter cherry trees with 58 native tree species, including 2 evergreen species, none of which makes up more than 20% of the total number of trees. Additionally, our new paving system is permeable. These improvements will provide better soil stabilization, improved runoff water quality, and habitat for local wildlife. 3. Please respond to the questions in the following chart - A No Net Loss analysis (prepared by a qualified biologist) must be prepared if the response to any of the questions in the chart g E E D "yes": 92018 WILL THE PROJECT: NO YEg( l ny`timr I vets a. Alter/remove vegetation in the shoreline jurisdiction? ❑ See comment / response next page b. Alter the river bank (i.e. re -slope bank, add armoring etc.)? ✓ D ❑ c. Add fill in the shoreline jurisdiction? n d. Discharge new stormwater to the river? U U e. Store or use hazardous materials in the shoreline jurisdiction? ✓ ❑ f. Construct an in- or over -water structure? ✓ ❑ ❑ g. Increase impervious surface in the shoreline jurisdiction? U iunity pment NO NET LOSS ANALYSIS 4. The way to achieve no net loss of ecological function is to mitigate the loss through one or a combination of the mitigation sequencing steps identified below. If preparing a No Net Loss analysis, please discuss how your project addresses the following mitigation sequencing steps (TMC 18.44.070 H.3.): a.

BACKGROUND In 2018, the City of Tukwila approved SRG's application for a shoreline substantial development permit to create a permanent exhibit of a B-52G Stratofortress 59-2584 Midnight Express aircraft and a Veteran's Memorial Plaza in a park -like setting which will be open to the public as part of the Museum of Flight. On - site work was to include constructing deep foundations for two tie -downs (a total of eight 18-inch diameter auger -cast pilings) to support the B-52 aircraft, a 650 square -foot rain garden, landscaping, walkways of permeable pavement, and a plaza. The plaza was to consist of a low seating wall, a statue depicting a returning aviator honoring veterans, 7 flag poles, educational exhibits, and lighting (see Figure 1). Due to direct conflicts with the proposed B-52 wing location, 13 existing trees along the south property line were to be removed, requiring 80 replacement trees in conformance with TMC 18.44.080.B. 23 replacement trees were to be planted on -site and in -lieu fees for the remaining 57 trees were to be paid into the City's tree replacement fund. Project Site The project site is part of a larger parcel located at 9229 E. Marginal Way South (Parcel #5729800010) and outlined in red in the Figure 2 below. Paved parking areas for Aviation High School and adjacent office uses surround the project site on the north and east sides. Aviation High School and the Museum of Flight's Aviation Pavilion are situated nearby, east of the project site. The site is separated from Slip 6 of the Duwamish River on the south side by a strip of land approximately 25 feet wide owned by the Boeing Company. The site has no direct access to the River. There is an existing King County storm drain easement running diagonal on the site from the southwest towards the northeast. Remaining on -site are three trailers currently accommodating the ongoing operations and activities of the Boeing Employees Amateur Radio Society (B.E.A.R.S.). The trailers house sensitive communication antennae and equipment and provide emergency communication services for Boeing and the local public service communities. The site is relatively flat and consists of exposed soil across much of the site and some crushed gravel. The Museum has undertaken clean-up actions on the site over the past 10 years and it was found to be successfully 2 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 remediated of hazardous materials per the Environmental Protection Agency in 2017. Existing trees on the site include 13 tall, mature trees along the southern property line, including 11 Lombardi poplars and 2 native Bitter cherries. Conditions of approval for the project were as follows: 1. Per the conclusions and recommendations of the Cultural Resource Assessment conducted for this project, the following actions are required: a. Develop and distribute an archaeological monitoring plan to DAHP and interested Native American Tribes prior to ground disturbance and monitoring. b. A professional archaeologist who meets the Secretary of the Interior standards for Professional Archaeology shall be on site to monitor excavation and placement of the eight auger -cast piles that form the foundation for the two tie -downs. c. Develop an Inadvertent Discovery Plan to guide actions in the event that archaeological materials are discovered when the monitor is not on site. Revision of the Shoreline Substantial Development Permit There is a King County storm drain pipe and 10-foot wide access easement running from the southwest corner of the site diagonally toward the northeast corner of the site. Under the original approved site plan, the aircraft would have to be moved to access the easement in case emergency repairs were needed. The Museum of Flight would need a minimum of seven days to move the plane because of the method by which it is mounted on the ground. The other option was to reroute the storm drain pipe at the Museum's expense of $1-$2 million. Neither of these options were acceptable to the Museum. After revisiting the site, it was determined that the plane could be relocated off the storm drain pipe and easement by moving it to the eastern portion of the site. 3 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 Figure 1.

Proposed Revised Site Plan YOMIATEDI / Iv. FINDINGS I L �aq 1.100110 There four main components to the shoreline permit revision, which are included on Attachments D through G: 1. Civil • The percentage of pervious area has increased by 15% over the original design. 17 parking spaces east of the site are to be removed. These are located outside of the 200' shoreline jurisdiction. • Total site disturbance area has increased by 1,229 square feet for the revised design (mainly for the removal of parking areas on east side of project. This area is located outside of the 200' shoreline jurisdiction. 2. Landscaping • The plane has been relocated so it will not conflict with the 10-foot wide King County storm drain pipe and access easement. • The plane will be elevated 5' above finish grade on a concrete plinth that slopes from 5' tall at the nose of 5 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 the plane to grade as it wraps around the plane. • The memorial has been simplified and is no longer elevated above grade. Instead it is at grade and enclosed by an 8" wide and 18" high seat wall. The flags are in a row in front of the memorial. • The new design proposes CIP concrete surfacing in place of Truegrid Pro surfacing. • Multiple landscape mounds have been proposed to enclose the space and help buffer the parking lot from the site. • The previous design proposed 23 trees to be planted on -site, while the new design proposes a total of 38. • The new design proposes three depressed areas in the landscape that allow for water to drain. 3. Structural • Main Landing Gear Supports: With the relocation of the main undercarriage supports away from the King County easement, deep foundations are no longer required. Shallow foundations will be provided per the recommendations in the Geotechnical Report. More specifically: o 18" of compacted structural fill will be provided below the footing. Auger cast piles will not be required. o The footing will be aligned to the aircraft centerline, instead of being rotated to clear the easement. o Size and thickness of the footing will be approximately that of the currently shown pier cap. o The grade elevation will be built up a few feet at these supports. The top of foundation will be at the current grade elevation, so as not to bear on fill. The 40" square pilaster will be increased in height as needed to raise the base plate to the final grade elevation. o No change expected to the steel support above the base plate. • Outrigging Supports: No changes anticipated. The location of one support structure will remain in the 200' shoreline jurisdiction but outside the 100' buffer area. 4. Miscellaneous • Two of the three existing B.E.A.R.S. trailers are to be relocated, along with the existing B.E.A.R.S. antenna, from the south portion of the site to the northwest corner. The third trailer is proposed to be removed due to the age and condition of the unit. V. SHORELINE REGULATIONS - REVIEW CRITERIA The request to revise the 2011 shoreline permit will be reviewed against the current Shoreline Master Program regulations as well as criteria from the WAC as the City's regulations do not include criteria for shoreline permit revisions. A. 18.44.060 High Intensity Environment — Permitted Uses The proposed permit revision is for a redesign of the B-52 Memorial Park that was originally approved by the City in L18-0031. The proposed use has not changed. The revision complies with the provisions of TMC 18.44.060. B. Development Standards — TMC 18.44.070.0 The following development standards apply to this project revision. • TMC 18.44.070.C.1 Standards — The proposed revision meets the development standards for the underlying Manufacturing Industrial Center/Heavy Industrial (MIC/H) zone. 6 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 • TMC 18.44.070.C.2. Setbacks and site configuration - The yard setback adjacent to the river is 100 feet. As in the approved permit, there is an undercarriage support for the aircraft's wingtip in the buffer which will be 8 feet in height and is a permitted use within this area. Only the location of the support structure within the buffer has changed. • TMC 18.44.070.C.3. Height restrictions - The relocation of the aircraft in the proposed revision does not exceed the maximum height limitation of 45 feet outside the river buffer but within the 200-foot shoreline jurisdiction. The revised height of the fuselage or main body of the B-52 plane, when mounted, is anticipated to be 22 feet 11 inches above grade. The revised height at the top of the vertical tail fin is anticipated to be 42 feet 1 inch above grade. The project structures will not block the views of the river for any residents. • TMC 18.44.070.C.4 Lighting — A revised lighting plan was not provided. Lights should be designed to limit spillover and glare on the property to the south where Slip 6 of the Duwamish River is located. Illumination of the pathways internal to the site should be provided if the site is intended to be used after dark or after Museum operating hours. A. Surface Water and Water Quality - TMC 18.44.070.D The proposed revision meets the requirements of this section. While concrete paving has replaced permeable paving, overall, the amount of pervious surface has increased by 15% as a result of removing 17 paved parking stalls and incorporating the area into the Park. The proposed revision also includes incorporating low impact development techniques such as a rain garden and increases the number of trees planted on the site from 27 to 38. B. Archaeological, Cultural and Historic Resources - TMC 18.44. 070.G A Cultural Resource Assessment was prepared for the project site prior to construction of the project and shared with the WA Department of Archaeology and Historic Preservation (DAHP) as part of the original permit approval. The conditions of approval regarding developing an archaeological monitoring plan, having a professional archaeologist on site during excavation, and developing an Inadvertent Discovery Plan will be required to ensure the provisions of TMC 18.44.070.G are met. C. Environmental Impact Mitigation - TMC 18.44.070.H a. Avoiding the impact altogether by not taking a certain action or parts of an action. b. Minimizing impacts by limiting the degree or magnitude of the action and its implementation by using appropriate technology or by taking affirmative steps to avoid or reduce impacts. c. Rectifying the impact by repairing, rehabilitating, or restoring the affected environment. d. Reducing or eliminating the impact over time by preservation and maintenance operations. e. Compensating for the impact by replacing, enhancing, or providing substitute resources or environments. f. Monitoring the impact and the compensation projects and taking appropriate corrective measures. There are no environmentally sensitive areas in the proposed project area. The proposed revision meets the requirements of these sections. D. Signs - TMC 18.44. 070.L No changes proposed. The proposed revision meets the requirements of this section. 7 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 • E. Vegetation Protection and Landscaping - TMC 18.44.080 The original permit proposed removing a total of 13 trees within the shoreline jurisdiction along the southern border of the proposed B-52 Bomber Memorial Park site. Per TMC 18.44.080.B, 80 native trees are required as replacement, which was determined based on the number and size of trees removed. The original permit proposed planting 23 of the required replacement trees on site and paying a fee in lieu into the City's tree replacement fund for each of the remaining 57 trees. The revised landscape plan (See Attachment G, Sheets L5.10 and 5.20) proposes planting a total of replacement 38 trees, 15 trees more than the original site plan. However, there is significant space available on the western portion of the site, even avoiding the King County easement area, where additional replacement trees could be planted. The replacement trees proposed include a native mix of Western Red Cedar, Shore Pine, and Oregon Ash. Several of the proposed replacement trees are not appropriate and require substitutions, per the City's Urban Environmentalist: • Malus Fusca (Oregon crab apple) is not appropriate for the site, as it prefers wetter soil conditions. • Rhamnus purshiana (Cascara) is a shrub and is not appropriate as a replacement tree. Plant spacings are not proposed for the shrubs, annuals, and grasses, and the legend for the shrub areas does not correspond with plan markings. The landscape plan specifies "native meadow mix" but does not specify the type of species included in the mix, which will also impact the amount of seed mix required to cover the area. "Turf grass" is proposed, but the species of grass is not identified. Since most of this planting is within the shoreline jurisdiction, a native grass seed mix is required. An existing tree located close to the park on the adjacent parcel to the south will be retained and its critical root zone protected during construction per TMC 18.54.070.1-11. Landscape maintenance will occur as needed for successful establishment of the plantings. The applicant will need to submit annual photos of all replacement trees to the City's Urban Environmentalist to ensure proper maintenance and a 100% survival rate for three years following the initial landscape inspection. Per TMC 18.44.080.B.5, the property owner is required to ensure the viability and long-term health of trees planted for replacement through proper care and maintenance for the life of the project. Replaced trees that do not survive must be replanted in the next appropriate season for planting. F. Public Access - TMC 18.44.100 No changes proposed. The proposed permit revision does not trigger the public access provisions of the Shoreline Master Program. The proposed revision meets the requirements of this section. G. Shoreline Design Guidelines - TMC 18.44.110 1. Relationship of Structure to Site. 2. Building Design. 3. Design of Public Access. The revised site plan contains the same park and public access elements, but in different locations. The proposed revision meets the requirements of this section. 8 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 VI. SEPA AND OTHER CITY APPROVALS An Environmental Checklist was submitted for the B-52 Memorial Park proposal (E16-0001) and a Notice of Decision was issued approving the proposal as a SEPA Planned Action on March 10, 2016. A Shoreline Tree Removal and Vegetation Clearing permit (L18-0030) was approved for this project on July 17, 2018. The applicant must obtain a building permit for park structures. VII. SHORELINE PERMIT REVISIONS The Tukwila Shoreline Master Program regulations do not include criteria for consideration of a revision to a shoreline substantial development permit. Therefore, the criteria from WAC 173-27-100 will be used. WAC 173-27-100 Revisions to Permits - Review Criteria "A permit revision is required whenever the applicant proposes substantive changes to the design, terms or conditions of a project from that which is approved in the permit. Changes are substantive if they materially alter the project in a manner that relates to its conformance to the terms and conditions of the permit, the master program and/or the policies and provisions of chapter 90.58 RCW. Changes which are not substantive in effect do not require approval of a revision. "When an applicant seeks to revise a permit, local government shall request from the applicant detailed plans and text describing the proposed changes. "(1) If local government determines that the proposed changes are within the scope and intent of the original permit, and are consistent with the applicable master program and the act, local government may approve a revision. "(2) "Within the scope and intent of the original permit" means all of the following: (a) No additional over water construction is involved except that pier, dock, or float construction may be increased by five hundred square feet or ten percent from the provisions of the original permit, whichever is less; (b) Ground area coverage and height may be increased a maximum of ten percent from the provisions of the original permit; (c) The revised permit does not authorize development to exceed height, lot coverage, setback, or any other requirements of the applicable master program except as authorized under a variance granted as the original permit or a part thereof; (d) Additional or revised landscaping is consistent with any conditions attached to the original permit and with the applicable master program; (e) The use authorized pursuant to the original permit is not changed; and (f) No adverse environmental impact will be caused by the project revision." In response to the criteria above: 1. The proposed changes are within the scope and intent of the original permit and consistent with the City's Master Program. 2. The scope of the proposed revision meets all of the criteria for "within the scope and intent of the original permit" 9 L18-0031 Shoreline Permit Revision Museum of Flight 852 Memorial Park November 8, 2018 a. No over -water construction is proposed; b. No increase in ground area coverage is proposed. The percentage of pervious area has increased by 15 percent over the original approved permit; no structure heights are being increased. c. The proposed permit revision does not request development that exceeds height, lot coverage setback or other requirements of the City's SMP. d. Additional landscaping is proposed in the project revision. 80 replacement trees are required. The original permit proposed 23 trees, while the revised design proposes a total of 38 trees. Some revisions related to the species of landscaping is required. e. The use authorized under the original permit is not changed. f. No adverse environmental impact will be caused by the project revision. VIII. CONCLUSION The proposed shoreline permit revision complies with WAC 173-27-100 — the work is within the scope and intent of the original shoreline permit. Changes were made to the original landscape plan and revisions are recommended. Also, a lighting plan should be submitted that is consistent with the requirements of TMC 18.44.070.C.4. However the lighting and landscaping revisions can be addressed as part of the building permit. IX. RECOMMENDATION Staff recommends approval of the shoreline substantial development permit revision with the following conditions that was required for approval of the original permit: 1. Per the conclusions and recommendations of the Cultural Resource Assessment conducted for this project, the following actions are required: a. Develop and distribute an archaeological monitoring plan to DAHP and interested Native American Tribes prior to ground disturbance and monitoring. b. A professional archaeologist who meets the Secretary of the Interior standards for Professional Archaeology shall be on site to monitor excavation and placement of the main undercarriage support structures. c. Develop an Inadvertent Discovery Plan to guide actions in the event that archaeological materials are discovered when the monitor is not on site. Staff recommends requiring the following additional actions as conditions of approval for the shoreline substantial development permit revision: 1. As part of the building permit submittal, ensure the following revisions are made: a. Sheet C002. Under General, add note "Contact City's Urban Environmentalist (Andrea.cummins@Tukwilawa.gov) prior to any construction activity taking place to verify tree protection measures are installed. b. Sheet L1.00. Show location of any lighting fixtures proposed for the project. c. Sheet L1.10. Add lighting fixtures to Furnishings Schedule. d. Sheet L5.10. Make these changes: 10 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 i. Malus fusca is appropriate for a wetland area and needs to be replaced with a more appropriate tree. ii. Rhamnus purshiana is a shrub, not a tree. Identify an appropriate replacement tree. iii. Add plant spacing for shrubs, annuals, grasses. iv. Legend for shrub areas does not correspond to plan. v. Native meadow mix. Specify the type of species included in this mix. Add amount of native meadow seed grass — need 5-25 Ibs per acre, depending on species. vi. Turf grass. Specify the species of grass proposed. Since most of this planting falls within the shoreline jurisdiction, it must be a native grass seed mix. e. Sheet L5.20. 80 replacement trees are required as part of the project; 38 replacement trees are proposed. There is significantly more area available for planting on the west side of the site, even with the King County easement. Add more replacement trees on site. If additional trees cannot be planted on the site the applicant shall pay $126 per tree into the City's Tree Replacement Fund. 11 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 ATTACHMENT A J B A L woOSPOSLO rokTUR tenx memo.

Shallow foundations will be provided per the recommendations in the Geotechnical Report. More specifically: o 18" of compacted structural fill will be provided below the footing. Auger cast piles will not be required. o The footing will be aligned to the aircraft centerline, instead of being rotated to clear the easement. o Size and thickness of the footing will be approximately that of the currently shown pier cap. o The grade elevation will be built up a few feet at these supports. The top of foundation will be at the current grade elevation, so as not to bear on fill. The 40" square pilaster will be increased in height as needed to raise the base plate to the final grade elevation. o No change expected to the steel support above the base plate. • Outrigging Supports: No changes anticipated.

The parking lot will be restriped and reconfigured to accommodate the displaced stalls. • The total site disturbance area has increased by 1,229 sq. ft. for the revised Phase 2 design [mainly because of the removal of the parking spaces on the east side of the site]. The project remains under 1 acre of site disturbance area. • The percentage of pervious area has increased by 1�5 percent over the original Phase 2 design [original Phase 2 design had 64% pervious area, revised Phase 2 design has 79% pervious area] Landscaping • The plane has been relocated so it will not conflict with the easement. • The plane will be elevated 5' above finish grade on a concrete plinth that slopes from 5' tall at the nose of the plane to grade as it wraps around the plane. • The memorial has been simplified and is no longer elevated above grade. Instead it is at grade and enclosed by an 8" wide and 18" high seat wall. The flags are in a row in front of the memorial. • The new design proposes SIP concrete sudaslin in place of Truegrid Pro surfacing. • Multiple landscape mounds have been proposed to enclose the space and help buffer the parking lot from the site. • The previous design proposed 23 trees, while the new design proposes a total of 38. • The new design proposes three depressed areas in the landscape that allow for water to drain.

Your permit is to create a permanent exhibit of a B-52 aircraft and a Veteran's Memorial Plaza in park -like section. Revisions are needed to comply with King County requirements relating to a storm drain easement and include relocating the aircraft and park elements to the eastern portion of the site, adding more landscaping, and changing to the under carriage support structures from a deep foundation to a shallow foundation. Your project is within the High Intensity shoreline environment designation of the Duwamish River, a shoreline of statewide significance. By law, local governments must review all SDPs for compliance with: • The Shoreline Management Act (Chapter 90.58 RCW) • Ecology's Substantial Development Permit approval criteria (Chapter 173-27-150 WAC) • The City of Tukwila Local Shoreline Master Program. Local governments, after reviewing SDPs for compliance, are required to submit them to Ecology. Your approved application for a revised SDP was received by Ecology. Other federal, state, and local permits may be required in addition to this shoreline permit. What Happens Next? At your own risk, you may begin your revised project immediately, provided you have all other required permits. However, a 21-day appeal period begins on November 9, 2018, the "date of filing." This waiting period allows anyone (including you) who disagrees with any aspect of this permit to appeal the decision to the state Shorelines Hearings Board. We recommend contacting the Shorelines Hearings Board at (360) 664-9160 before beginning permit activities to ensure that no appeal has been filed. Information on appeals is also posted at The Museum of Flight November 9, 2018 Page 2 of 2 http://www.eluho.wa.gov/Decision/Search Cases. Select "Shorelines Hearings Board" from the drop down menu labeled "Board" and enter "Search." The most current appeal will appear on top. If m want to appeal this decision, you can find appeal instructions (Chapter 461-08 WAC) at the Shorelines Hearings Board website above. They are also posted on the website of the Washington State Legislature at: http://apps.leg.wa.gov/wac.

The first phase consisted of: grading the site, creating a water connection to an existing fire loop, installing irrigation and planting, madding parking, and providing a small picnic area for use by Raisbeck Aviation High School students. The general effort is intended to beautify the site and lay the groundwork for a future phase. Phase II includes the placement of a restored Boeing B-52G Stratofortress 59-2584 Midnight Express and other interpretive and landscape elements. The aircraft will reside in a park -like setting where visitors can reflect upon the B-52 and the needy 8,000 other US military aircraft lost during Vietnam. The plane will be joined by a statue depicting a retuming aviator honoring veterans who served in all military brandies between 1964 and 1975. The park will also feature an exhibit about the dozens of types of planes and helicopters flown during the war. Schedule Apr 1.

Project File Number: Applicant: Type of Permit: Project Description: LM I. PROJECT INFORMATION L18-0031 Michael Canales, SRG Partnership, Inc. Shoreline Substantial Development Permit Revision In 2018, the Museum of Flight applied and received approval for a shoreline substantial development permit to construct a permanent exhibit of a B-52G Stratofortress 59-2584 Midnight Express aircraft and a Veteran's Memorial Plaza in a park -like setting. The project site is not adjacent to the Duwamish River but a significant portion of the project is located within 200 feet of the Ordinary High Water Mark (OHWM) of the river. The current request is to revise the previously approved shoreline substantial development permit for the Museum of Flight's B-52 Memorial Park to comply with King County requirements relating to access to the 10-foot wide storm drain easement that exists on the project site. Proposed revisions to the site plan include relocating the aircraft and park elements to the eastern portion of the site, adding more landscaping, and changing the type of main under carriage support structures from a deep foundation Page I of4 July 19, 2018 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone 206-431-3670 • Fax 206-431-3665 Location: Associated Files: Comprehensive Plan Designation/Zoning District: to a shallow foundation.

III. BACKGROUND In 2018, the City of Tukwila approved SRG's application for a shoreline substantial development permit to create a permanent exhibit of a B-52G Stratofortress 59-2584 Midnight Express aircraft and a Veteran's Memorial Plaza in a park -like setting which will be open to the public as part of the Museum of Flight. On - site work was to include constructing deep foundations for two tie -downs (a total of eight 18-inch diameter auger -cast pilings) to support the B-52 aircraft, a 650 square -foot rain garden, landscaping, walkways of permeable pavement, and a plaza. The plaza was to consist of a low seating wall, a statue depicting a returning aviator honoring veterans, 7 flag poles, educational exhibits, and lighting (see Figure 1). Due to direct conflicts with the proposed B-52 wing location, 13 existing trees along the south property line were to be removed, requiring 80 replacement trees in conformance with TMC 18.44.080.B. 23 replacement trees were to be planted on -site and in -lieu fees for the remaining 57 trees were to be paid into the City's tree replacement fund. Project Site The project site is part of a larger parcel located at 9229 E. Marginal Way South (Parcel #5729800010) and outlined in red in the Figure 2 below. Paved parking areas for Aviation High School and adjacent office uses surround the project site on the north and east sides. Aviation High School and the Museum of Flight's Aviation Pavilion are situated nearby, east of the project site. The site is separated from Slip 6 of the Duwamish River on the south side by a strip of land approximately 25 feet wide owned by the Boeing Company. The site has no direct access to the River. There is an existing King County storm drain easement running diagonal on the site from the southwest towards the northeast. Remaining on -site are three trailers currently accommodating the ongoing operations and activities of the Boeing Employees Amateur Radio Society (B.E.A.R.S.). The trailers house sensitive 2 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 communication antennae and equipment and provide emergency communication services for Boeing and the local public service communities. The site is relatively flat and consists of exposed soil across much of the site and some crushed gravel. The Museum has undertaken clean-up actions on the site over the past 10 years and it was found to be successfully remediated of hazardous materials per the Environmental Protection Agency in 2017. Existing trees on the site include 13 tall, mature trees along the southern property line, including 11 Lombardi poplars and 2 native Bitter cherries. Conditions of approval for the project were as follows: 1. Per the conclusions and recommendations of the Cultural Resource Assessment conducted for this project, the following actions are required: a. Develop and distribute an archaeological monitoring plan to DAHP and interested Native American Tribes prior to ground disturbance and monitoring. b. A professional archaeologist who meets the Secretary of the Interior standards for Professional Archaeology shall be on site to monitor excavation and placement of the eight auger -cast piles that form the foundation for the two tie -downs. c. Develop an Inadvertent Discovery Plan to guide actions in the event that archaeological materials are discovered when the monitor is not on site. Revision of the Shoreline Substantial Development Permit There is a King County storm drain pipe and 10-foot wide access easement running from the southwest corner of the site diagonally toward the northeast corner of the site. Under the original approved site plan, the aircraft would have to be moved to access the easement in case emergency repairs were needed. The Museum of Flight would need a minimum of seven days to move the plane because of the method by which it is mounted on the ground. The other option was to reroute the storm drain pipe at the Museum's expense of $1-$2 million. Neither of these options were acceptable to the Museum. After revisiting the site, it was determined that the plane could be relocated off the storm drain pipe and easement by moving it to the eastern portion of the site. 3 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 Figure 1.

Proposed Revised Site Plan UUtlU+ / / it ILL= • • IV. FINDINGS raPPIM011 There four main components to the shoreline permit revision, which are included on Attachments D and E: 1. Civil • The percentage of pervious area has increased by 15% over the original design. • 17 parking spaces east of the site are to be removed. These are located outside of the 200' shoreline jurisdiction. • Total site disturbance area has increased by 1,229 square feet for the revised design (mainly for the removal of parking areas on east side of project. This area is located outside of the 200' shoreline jurisdiction. 2. Landscaping • The plane has been relocated so it will not conflict with the 10-foot wide King County storm drain pipe and access easement. • The plane will be elevated 5' above finish grade on a concrete plinth that slopes from 5' tall at the nose of 5 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 the plane to grade as it wraps around the plane. • The memorial has been simplified and is no longer elevated above grade. Instead it is at grade and enclosed by an 8" wide and 18" high seat wall. The flags are in a row in front of the memorial. • The new design proposes CIP concrete surfacing in place of Truegrid Pro surfacing. • Multiple landscape mounds have been proposed to enclose the space and help buffer the parking lot from the site. • The previous design proposed 23 trees to be planted on -site, while the new design proposes a total of 38. • The new design proposes three depressed areas in the landscape that allow for water to drain. 3. Structural • Main Landing Gear Supports: With the relocation of the main undercarriage supports away from the King County easement, deep foundations are no longer required. Shallow foundations will be provided per the recommendations in the Geotechnical Report. More specifically: o 18" of compacted structural fill will be provided below the footing. Auger cast piles will not be required. o The footing will be aligned to the aircraft centerline, instead of being rotated to clear the easement. o Size and thickness of the footing will be approximately that of the currently shown pier cap. o The grade elevation will be built up a few feet at these supports. The top of foundation will be at the current grade elevation, so as not to bear on fill. The 40" square pilaster will be increased in height as needed to raise the base plate to the final grade elevation. o No change expected to the steel support above the base plate. • Outrigging Supports: No changes anticipated. The location of one support structure will remain in the 200' shoreline jurisdiction but outside the 100' buffer area. 4. Miscellaneous • Two of the three existing B.E.A.R.S. trailers are to be relocated, along with the existing B.E.A.R.S. antenna, from the south portion of the site to the northwest corner. The third trailer is proposed to be removed due to the age and condition of the unit. V. SHORELINE REGULATIONS - REVIEW CRITERIA The request to revise the 2011 shoreline permit will be reviewed against the current Shoreline Master Program regulations as well as criteria from the WAC as the City's regulations do not include criteria for shoreline permit revisions. A. 18.44.060 High Intensity Environment — Permitted Uses The proposed permit revision is for a redesign of the B-52 Memorial Park that was originally approved by the City in L18-0031. The proposed use has not changed. The revision complies with the provisions of TMC 18.44.060. B. Development Standards — TMC 18.44.070.0 The following development standards apply to this project revision. • TMC 18.44.070.C.1 Standards — The proposed revision meets the development standards for the underlying Manufacturing Industrial Center/Heavy Industrial (MIC/H) zone. 6 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 • TMC 18.44.070.C.2. Setbacks and site configuration - The yard setback adjacent to the river is 100 feet. As in the approved permit, there is an undercarriage support for the aircraft's wingtip in the buffer which will be 8 feet in height and is a permitted use within this area. Only the location of the support structure within the buffer has changed. • TMC 18.44.070.C.3. Height restrictions - The relocation of the aircraft in the proposed revision does not exceed the maximum height limitation of 45 feet outside the river buffer but within the 200-foot shoreline jurisdiction. The revised height of the fuselage or main body of the B-52 plane, when mounted, is anticipated to be 22 feet 11 inches above grade. The revised height at the top of the vertical tail fin is anticipated to be 42 feet 1 inch above grade. The project structures will not block the views of the river for any residents. • TMC 18.44.070.C.4 Lighting — A revised lighting plan was not provided. Lights should be designed to limit spillover and glare on the property to the south where Slip 6 of the Duwamish River is located. Illumination of the pathways internal to the site should be provided if the site is intended to be used after dark or after Museum operating hours. A. Surface Water and Water Quality - TMC 18.44.070.D The proposed revision meets the requirements of this section. While concrete paving has replaced permeable paving, overall, the amount of pervious surface has increased by 15% as a result of removing 17 paved parking stalls and incorporating the area into the Park. The proposed revision also includes incorporating low impact development techniques such as a rain garden and increases the number of trees planted on the site from 27 to 38. B. Archaeological, Cultural and Historic Resources - TMC 18.44. 070.G A Cultural Resource Assessment was prepared for the project site prior to construction of the project and shared with the WA Department of Archaeology and Historic Preservation (DAHP) as part of the original permit approval. The conditions of approval regarding developing an archaeological monitoring plan, having a professional archaeologist on site during excavation, and developing an Inadvertent Discovery Plan will be required to ensure the provisions of TMC 18.44.070.G are met. C. Environmental Impact Mitigation - TMC 18.44.070.H a. Avoiding the impact altogether by not taking a certain action or parts of an action. b. Minimizing impacts by limiting the degree or magnitude of the action and its implementation by using appropriate technology or by taking affirmative steps to avoid or reduce impacts. c. Rectifying the impact by repairing, rehabilitating, or restoring the affected environment. d. Reducing or eliminating the impact over time by preservation and maintenance operations. e. Compensating for the impact by replacing, enhancing, or providing substitute resources or environments. f. Monitoring the impact and the compensation projects and taking appropriate corrective measures. There are no environmentally sensitive areas in the proposed project area. The proposed revision meets the requirements of these sections. D. Signs - TMC 18.44. 070.L No changes proposed. The proposed revision meets the requirements of this section. 7 L18-0031 Shoreline Permit Revision Museum of Flight B52 Memorial Park November 8, 2018 E. Vegetation Protection and Landscaping - TMC 18.44.080 The original permit proposed removing a total of 13 trees within the shoreline jurisdiction along the southern border of the proposed B-52 Bomber Memorial Park site. Per TMC 18.44.080.B, 80 native trees are required as replacement, which was determined based on the number and size of trees removed. The original permit proposed planting 23 of the required replacement trees on site and paying a fee in lieu into the City's tree replacement fund for each of the remaining 57 trees. The revised landscape plan (See Attachment E, Sheets L5.10 and 5.20) proposes planting a total of replacement 38 trees, 15 trees more than the original site plan. However, there is significant space available on the western portion of the site, even avoiding the King County easement area, where additional replacement trees could be planted. The replacement trees proposed include a native mix of Western Red Cedar, Shore Pine, and Oregon Ash. Several of the proposed replacement trees are not appropriate and require substitutions, per the City's Urban Environmentalist: • Malus Fusca (Oregon crab apple) is not appropriate for the site, as it prefers wetter soil conditions. • Rhamnus purshiana (Cascara) is a shrub and is not appropriate as a replacement tree. Plant spacings are not proposed for the shrubs, annuals, and grasses, and the legend for the shrub areas does not correspond with plan markings. The landscape plan specifies "native meadow mix" but does not specify the type of species included in the mix, which will also impact the amount of seed mix required to cover the area. "Turf grass" is proposed, but the species of grass is not identified. Since most of this planting is within the shoreline jurisdiction, a native grass seed mix is required. An existing tree located close to the park on the adjacent parcel to the south will be retained and its critical root zone protected during construction per TMC 18.54.070.1-11. Landscape maintenance will occur as needed for successful establishment of the plantings. The applicant will need to submit annual photos of all replacement trees to the City's Urban Environmentalist to ensure proper maintenance and a 100% survival rate for three years following the initial landscape inspection. Per TMC 18.44.080.B.5, the property owner is required to ensure the viability and long-term health of trees planted for replacement through proper care and maintenance for the life of the project. Replaced trees that do not survive must be replanted in the next appropriate season for planting. F. Public Access - TMC 18.44.100 No changes proposed. The proposed permit revision does not trigger the public access provisions of the Shoreline Master Program. The proposed revision meets the requirements of this section. G. Shoreline Design Guidelines - TMC 18.44.110 1. Relationship of Structure to Site. 2. Building Design. 3. Design of Public Access. The revised site plan contains the same park and public access elements, but in different locations. The proposed revision meets the requirements of this section. 8 L18-0031 Shoreline Permit Revision Museum of Flight 852 Memorial Park November 8, 2018 VI. SEPA AND OTHER CITY APPROVALS An Environmental Checklist was submitted for the B-52 Memorial Park proposal (E16-0001) and a Notice of Decision was issued approving the proposal as a SEPA Planned Action on March 10, 2016. A Shoreline Tree Removal and Vegetation Clearing permit (L18-0030) was approved for this project on July 17, 2018. The applicant must obtain a building permit for park structures. VII. SHORELINE PERMIT REVISIONS The Tukwila Shoreline Master Program regulations do not include criteria for consideration of a revision to a shoreline substantial development permit. Therefore, the criteria from WAC 173-27-100 will be used. WAC 173-27-100 Revisions to Permits - Review Criteria "A permit revision is required whenever the applicant proposes substantive changes to the design, terms or conditions of a project from that which is approved in the permit. Changes are substantive if they materially alter the project in a manner that relates to its conformance to the terms and conditions of the permit, the master program and/or the policies and provisions of chapter 90.58 RCW. Changes which are not substantive in effect do not require approval of a revision. "When an applicant seeks to revise a permit, local government shall request from the applicant detailed plans and text describing the proposed changes. "(1) If local government determines that the proposed changes are within the scope and intent of the original permit, and are consistent with the applicable master program and the act, local government may approve a revision.

PROJECT DESCRIPTION This project proposes to create a permanent exhibit of a B-52G Stratofortress 59-2584 Midnight Express aircraft and a Veteran's Memorial Plaza in a park -like setting which will be open to the public as part of the Museum of Flight. On -site work includes constructing deep foundations for two tie -downs (a total of eight 18-inch diameter auger -cast pilings) to support the B-52 aircraft, a 650 square -foot rain garden, landscaping, walkways of permeable pavement, and a plaza. The plaza will consist of a low seating wall, a statue depicting a returning aviator honoring veterans, 7 flag poles, educational exhibits, and lighting (see Figure 1). Due to direct conflicts with the proposed B-52 wing location, 13 existing trees along the south property line will be removed, requiring 80 replacement trees in conformance with TMC 18.44.080.B. 23 replacement trees will be planted on -site and in -lieu fees for the remaining 57 trees will be paid into the City's tree replacement fund. Project Site The project site is part of a larger parcel located at 9229 E. Marginal Way South (Parcel #5729800010) and outlined in red in the Figure 2 below. Paved parking areas for Aviation High School and adjacent office uses surround the project site on the north and east sides. Aviation High School and the Museum of Flight's Aviation Pavilion are situated nearby, east of the project site. The site is separated from Slip 6 of the Duwamish River on the south side by a strip of land approximately 25 feet wide owned by the Boeing Company. The site has no direct access to the River. There is an existing King County storm drain easement running diagonal on the site from the southwest towards the northeast. Remaining on -site are three trailers currently accommodating the ongoing operations and activities of the Boeing Employees Amateur Radio Society (B.E.A.R.S.). The trailers house sensitive communication antennae and equipment, and provide emergency communication services for Boeing and the local public service communities. The site is relatively flat and consists of exposed soil across much of the site and some crushed gravel. The Museum has undertaken clean-up actions on the site over the past 10 years and it was found to be successfully remediated of hazardous materials per the Environmental Protection Agency in 2017. Existing trees on the site include 13 tall, mature trees along the 2 Shoreline Substantial Development July 19, 2018 southern property line, including 11 Lombardi poplars and 2 native Bitter cherries.

Project Location 7.1 / Slip 6 Duwamish River 4. TUKWILA SHORELINE MASTER PROGRAM Aviation High School Museum of Flight Aviation Pavilion The City of Tukwila adopted a new Shoreline Master Program (SMP) on August 15, 2011 which was approved by the Washington State Department of Ecology on October 14, 2011 and became effective October 28, 2011. This project is subject to the new Shoreline Master Program. A. SHORELINE ENVIRONMENT DESIGNATION The shoreline environment designation for the site is High Intensity; the purpose of the High Intensity environment is to focus on water -oriented commercial, transportation, and industrial uses, with a priority on water -dependent uses. Non -water oriented uses should not be allowed except as part of a mixed use development, in limited situations where they would not conflict with or limit opportunities for water -oriented uses, or on sites where there is no direct access to the shoreline. New development should promote vegetation conservation and enhancement, sensitive areas protection, and preservation of water quality to assure no net loss of shoreline ecological functions. Visual and public access should be provided, where feasible. The shoreline buffer in the High Intensity environment is measured as 100 feet from the OHWM of the Duwamish River. A portion of the 8-52 Memorial Park project, including one support structure for the B-52 aircraft landing gear, a rain garden, landscaping, and walkways of permeable pavement fall within the 100 foot shoreline buffer. Other project elements, including the two deep foundations for two tie -downs (a total of eight 18-inch diameter auger - cast pilings) for the aircraft and the half of the park plaza, lie outside the buffer but within the 4 Shoreline Substantial Development July 19, 2018 200 foot shoreline jurisdiction. There is a small portion of the site that is located completely outside of the shoreline environment — see Figure 3. Figure 3. Shoreline Buffers 200' from OHWM 100' from OHWM B. SHORELINE MASTER PROGRAM GOALS AND POLICIES The following section discusses the Shoreline Master Program (SMP) goals and policies that apply to this project and are excerpted from Chapter 6 of the City's SMP. 6.3 Land Development Use and Economic Vitality Goal: Development along the shoreline that fosters the economic vitality of Tukwila while preserving the long-term benefits of the river. Policy 5.3.8: Ensure that non -water dependent shoreline development in the MIC provides for shoreline multiple uses to the extent that site security and the success of industrial operations are not jeopardized; ensures no net Toss of shoreline function and provides adequate mitigation for the loss of shoreline multiple use opportunities. Applicant Response: The Museum of Flight (MOF) B-52 Park is an extension of the Museum of Flight Air Pavilion, and the greater Museum complex. The MOF draws over half a million visitors 5 Shoreline Substantial Development July 19, 2018 per year and employs nearly 200 people. The B-52 Park will add an additional exhibit of a restored B-52G, while maintaining visual access to the river and an ecologically restored park area for visitors to enjoy. The applicant feels this use meets the goals for both economic vitality and preserving the benefits of the river. The B-52 project site is within the shoreline buffer but is separated from the actual high-water line by a 25' strip of land owned by the Boeing Company so that there is no direct access to the river from the project site. Shoreline access is controlled by the Boeing Company. The applicant believes that the development of the B-52 park provides flexibility for future development or shoreline function in that it has no permanent structures other than footings for the aircraft in the shoreline buffer area. Staff concurs with the applicant's response. The applicant has also provided a No Net Loss (NNL) checklist which is provided as Attachment 4 to this staff report. A NNL analysis of shoreline function was not required of the applicant, as the applicant is improving the existing soil, water, and shoreline jurisdictions conditions. Prior to the improvements, the site consisted of compacted gravel paving. Park improvements will include landscaping, a rain garden, and permeable paving, resulting in better soil stabilization, improved runoff water quality, and enhanced habitat for wildlife. 6.6 Access and Recreational Use Goal: Increase the amount and diversity of opportunities for public recreation and access to and along the river, including visual and cultural access, access to the water's edge, opportunities for small boat navigation and access, and connections to other neighborhoods, consistent with the shoreline character. Applicant Response: The B-52 project site is within the shoreline buffer, but is separated from the actual high-water line by a 25 foot strip of land owned by the Boeing Company so that there is no direct access to the river from the project site. However, the applicant is creating a park space that will be open to the public with many recreational amenities, including a loop path around the aircraft and a memorial plaza located on a raised mound surrounded by lawn from which one can view to the river. Staff concurs with the applicant's response. Policy 5.6.14: For MIC properties not included in the King County Green River Trail Plan, require shoreline development to provide public access or a private natural area in lieu of public access, or otherwise mitigate the loss of public access. Applicant Response: The B-52 project is providing nearly an acre of open space with a native meadow planting, raingarden, loop path and memorial plaza. Because the project site is not directly adjacent to the river and is very flat, views from the southwest corner nearest the high- water line are not very clear. Therefore, the plaza area will be raised to allow for views to the 6 Shoreline Substantial Development July 19, 2018 river. The plaza and paths all meet ADA requirements, and furnishings including benches, handrails, and site lighting are provided. The park plantings are native/adaptive in accordance with Vegetation Protection and Landscaping section of the Tukwila Shoreline Master Program, and any tree removal is being either replaced or paid for by the Museum in lieu of planting additional trees, based on the restrictions inherent in our program. Staff concurs with the applicant's response. The project site is not included in the King County Green River Trail Plan. Policy 5.10.1: Design, locate, and manage shoreline development including streets, flood control projects, surface water drainage and sewer systems, clearing and grading activities, and landscaping in a manner which minimizes opportunities for pollutants to enter the river, provides erosion control and otherwise protects water quality. Applicant Response: Minimal grading will occur on the site. The former compacted gravel parking area was de -compacted and replaced with hydroseeded meadow as part of the first phase of this project, which has been completed. Next phases will enhance the meadow and add additional planting and permeable paving. At the low point of the site where water currently pools, a rain garden will be added to increase infiltration and filter any pollutants that may be carried with runoff across the site. Staff concurs with the applicant's response. 5. SHORELINE REGULATIONS TMC 18.44.130.6.3. Shoreline Administration states that a substantial development permit shall be granted only when the development proposed is consistent with the shoreline master program. The relevant SMP policies were discussed above. Below is a discussion of the relevant shoreline master program regulations that are incorporated into the zoning code that apply to this permit application. A. Permitted Uses: TMC 18.44.060 identifies permitted uses in the High Intensity environment. Under TMC 18.44.060.B.1 the following components of the proposed project are listed as permitted uses in the High Intensity buffer (100 feet from OHWM): c. Public parks, recreation and open space. d. Public and/or private promenades, footpaths or trails. f. Recreation structures such as benches, tables, viewpoints, and picnic shelters, provided no such structure shall exceed 15 feet in height and 25 square feet in area and no views of the shoreline are blocked from adjacent properties. Project elements within the High Intensity buffer consist of one support structure for the B-52 aircraft landing gear, a rain garden, landscaping, and walkways of permeable pavement. 7 Shoreline Substantial Development July 19, 2018 TMC 18.44.060.C.1 sets forth the permitted uses in the High Intensity environment area located outside of the buffer (within 200 feet of the OHWM): "All uses permitted in the High Intensity Buffer and/or the Shoreline Use Matrix may be allowed." Project elements within this area are considered permitted uses, consisting of two deep foundations for two tie -downs (a total of eight 18-inch diameter auger -cast pilings) to support the B-52 aircraft, landscaping, walkways of permeable pavement, and a plaza. The plaza will consist of a low seating wall, a statue depicting a returning aviator honoring veterans, 2 of the 7 flag poles, educational exhibits, and lighting. B. Development Standards - TMC 18.44.070.0 The following development standards apply to this project. • TMC 18.44.070.C.1 Standards — The proposed project meets the development standards for the underlying Manufacturing Industrial Center/Heavy Industrial (MIC/H) zone. • TMC 18.44.070.C.2. Setbacks and site configuration - The yard setback adjacent to the river is 100 feet. The one structure proposed within the buffer is an undercarriage support for the aircraft's wingtip which will be 8 feet in height and is a permitted use within this area. • TMC 18.44.070.C.3. Height restrictions - The project does not exceed the maximum height limitation of 15 feet in within the River Buffer area or 45 outside the river buffer but within the shoreline jurisdiction. The maximum height of the fuselage or main body of the B-52 plane, when mounted, is anticipated to be 17 feet 11 inches above grade. The top of the vertical tail fin is anticipated to be 42 feet 1 inch above grade. The project structures will not block the views of the river for any residents. • TMC 18.44.070.C.4 Lighting — Two lighting fixtures mounted on 25 foot -tall poles will illuminate the site and be designed to limit spillover and glare on the property to the south where Slip 6 of the Duwamish River is located. Three uplights will illuminate the statue and flag pole base. Additional illumination of the pathways internal to the site is not provided, as the site is not intended to be used after dark or after Museum operating hours. C. Surface Water and Water Quality - TMC 18.44.070.D The project meets the requirements of this section, including incorporating low impact development techniques such as a rain garden and permeable pavement for the pedestrian pathways, and significant amounts of landscaping. D. Archaeological, Cultural and Historic Resources - TMC 18.44. 070.G A Cultural Resource Assessment was prepared for the project site prior to construction of the project and shared with the WA Department of Archaeology and Historic Preservation (DAHP). See Attachments 6 and 8 for their comment letters. The project will be conditioned to ensure the provisions of TMC 18.44.070.G are met. See Section 6 — Public Comments below for more discussion. 8 Shoreline Substantial Development July 19, 2018 E. Environmental Impact Mitigation - TMC 18.44.070.H All shoreline development and uses will occur in a manner that results in no net Toss of shoreline ecological functions through the careful location and design of all allowed development and uses. An Environmental Checklist was submitted for the B-52 Memorial Park Phase 1 and 2 (E16-0001) and a Notice of Decision was issued approving the proposal as a Planned Action on March 10, 2016. a. Avoiding the impact altogether by not taking a certain action or parts of an action. The project site is not adjacent to the Green River. The site is separated from Slip 6 on the Green River by approximately 25 feet of property owned by Boeing. The project avoids construction on the riverbank and underwater. b. Minimizing impacts by limiting the degree or magnitude of the action and its implementation by using appropriate technology or by taking affirmative steps to avoid or reduce impacts. • 13 trees will be removed on -site due to disease and site layout constrictions, and per TMC 18.44.080.B, 80 replacement trees are required. A minimum of 23 trees will be planted on site by the applicant and payment into the City's tree fund is allowed for up to 57 of the replacement trees. A tree adjacent to the site will be retained and protected during construction. • Low Impact Developments (LID), including a rain garden and pathways of permeable pavement will be incorporated in the proposed project to address runoff. • Landscaping, including native vegetation, will replace the former paving and compacted soil and gravel surfacing. • All pollution -generating impervious surface area within the site disturbance area was removed as part of previous work on the site in 2016. • Park lighting will be directed away from the river to prevent spillover. c. Rectifying the impact by repairing, rehabilitating, or restoring the affected environment. d. Reducing or eliminating the impact over time by preservation and maintenance operations. e. Compensating for the impact by replacing, enhancing, or providing substitute resources or environments. f. Monitoring the impact and the compensation projects and taking appropriate corrective measures. Impacts to vegetation in the shoreline jurisdiction will be addressed by increasing the amount of trees on the site. A Shoreline Tree Removal and Vegetation Clearing permit to remove 13 existing trees within the shoreline environment was approved on July 17, 2018. Per TMC 18.44.080.B, 80 replacement trees are required, which was determined based on the number and size of trees removed. The applicant will plant a minimum of 23 of the required replacement trees on site. The applicant will also pay a fee in lieu into the City's tree replacement fund for each of the remaining 57 trees which are not able to be planted on site due to King County easement restrictions and the design intent and the operational requirements of the project. An existing tree located close to the park on the 9 Shoreline Substantial Development July 19, 2018 adjacent parcel to the south will be retained and its critical root zone protected during construction. F. Signs - TMC 18.44. 070.L Signs within the shoreline jurisdiction will be limited to interpretive signs. G. Vegetation Protection and Landscaping - TMC 18.44.080 A total of 13 trees will be removed within the shoreline jurisdiction along the southern border of the proposed B-52 Bomber Memorial Park site when this project is implemented. The subject trees include 11 Lombardi poplars and two native Bitter cherries, ranging from 25 feet to 85 feet in height and 8 to 26 inches in diameter at 4.5 feet from the ground. Three trees were previously topped at 35 feet, and two trees are diseased and considered not viable. Per TMC 18.44.080.B, 80 native trees are required as replacement, which was determined based on the number and size of trees removed. The applicant is proposing planting 23 of the required replacement trees on site and paying a fee in lieu into the City's tree replacement fund for each of the remaining 57 trees. A number of alternatives were considered to increase the proposed number of replacement trees planted on site, including adding trees to the eastern portion of the site, screening the B.E.A.R.S. trailers on the south side of the property, adding trees in large planters along the King County stormwater easement that could be moved, if needed, and planting trees off -site adjacent to Slip 6. The applicant believed placing more trees on the site was not feasible due to the following reasons: • Planting more trees on the eastern border of the site conflicted with project goals of maintaining visibility of the military branch flags, sculpture, and the aircraft from surrounding vantage points. • Operational requirements of the site, including King County's requirement to keep access to a storm drain manhole along the western portion of the site free of trees. • At the south side of the project site, the Museum of Flight has long accommodated the ongoing operations and activities of the Boeing Employees Amateur Radio Society (B.E.A.R.S.). The trailers here house sensitive communication antennae and equipment, and provide emergency communication services for Boeing and the local public service communities. Existing trees are being removed from this area in order to limit the potential for damage or interference with B.E.A.R.S. operations. • Trees in planters have a low survival rate and have limited mobility. • Given the known soil conditions on the project site, it is speculated that adjacent properties may likely contain contamination, unstable soils, or invasive existing plantings, suggesting that a more intrusive soils investigation, tree survey, and planting study could ensue. The Boeing parcels adjacent to the project site and to Slip 6 (King County Parcel Nos. 562420-1038 and 562420-1032) are further understood to be high - security facilities, and the applicant believes coordination of existing conditions investigations and tree plantings at Slip 6 to be operationally prohibitive. 10 Shoreline Substantial Development July 19, 2018 On -site trees to be removed ,44 The 23 replacement trees to be planted on -site include a native mix of Western Red Cedar, Cascara, Shore Pine, and Oregon Ash. An existing tree located close to the park on the adjacent parcel to the south will be retained and its critical root zone protected during construction per TMC 18.54.070.1-11. Tree removal and replacement was approved in a Notice of Decision issued on July 17, 2018. Landscape maintenance will occur as needed for successful establishment of the plantings. The applicant will need to submit annual photos of all 23 trees to the City's Urban Environmentalist to ensure proper maintenance and a 100% survival rate for three years following the initial landscape inspection. Per TMC 18.44.080.B.5, the property owner is required to ensure the viability and long-term health of trees planted for replacement through proper care and maintenance for the life of the project. Replaced trees that do not survive must be replanted in the next appropriate season for planting. H. Public Access - TMC 18.44.100 Public access is not required for this project as the site does not abut the Duwamish River shoreline. However, the B-52 park project is providing nearly an acre of open space with a loop path and memorial plaza. The plaza will be raised to allow for views to the river. The plaza and paths all meet ADA requirements, and furnishings including benches, handrails, and site lighting are provided. I. Shoreline Design Guidelines - TMC 18.44.110 1. Relationship of Structure to Site. 2. Building Design. These sections of the TMC do not apply as no buildings are being constructed, only the 11 Shoreline Substantial Development July 19, 2018 support structures for the B-52 aircraft. 3. Design of Public Access. The project is consistent with the public access design guidelines. An attractively designed and welcoming park will provide visual access to the Duwamish River and nearly an acre of open space with a loop trail to view the B-52 plane and the surrounding area. Site landscaping will consist of native vegetation, consistent with TMC 18.44.080. Durable seating is provided via a low seating wall around the memorial plaza and four benches of metal and wood. Environmentally friendly porous pavement is used on the pedestrian pathways. 6. PUBLIC COMMENTS Comments were received during the Notice of Application period from Gretchen Kaehler of the Washington Department of Archaeology and Historic Preservation on May 24, 2018 (see Attachment 6). Ms. Kaehler notified staff that the project area has a high potential to contain archaeological resources due to the site's location on an old Oxbow Bend of the Duwamish River and proximity to four recorded precontact archaeological sites within 1 mile of the project. She requested that a professional archaeological survey of the project area prior to ground disturbance be conducted to ensure that protected resources would not be inadvertently damaged during construction. Response: A Cultural Resource Assessment was conducted in response to comments from DAHP and submitted to the City, DAHP, King County, and the Muckleshoot, Snoqualmie, Suquamish, and Tulalip tribes on June 26, 2018. The assessment included background research using sources such as geotechnical reports, public records, and historic maps and resources to develop a full of the history of land use and archaeological potential in the project area. The conclusions and recommendations of the Cultural Resource Assessment include the following: "Parcel history, geotechnical borings, and nearby monitoring indicate that at least 4 to 7 feet of recent fill, and possibly more, are present in the study area. Groundwater is likely present at around 10 feet, representing a likely lower boundary of occupation or use. Native sediments could be present between 4 and 10 feet below the surface. Archaeological potential, however, is low to moderate. The native ground surface may have been removed by the cleanup, if not by prior industrial activity. However, the presence of historical artifacts at 12 feet below the surface on the adjacent parcel indicates that some potential remains. The footprint of ground disturbance deeper than 4 feet below the surface is limited to the eight auger -cast piles that form the foundation for the two tie - downs for the project. If possible, given construction methods, archaeological monitoring should occur at those locations, to comply with TMC 18.50.110. An archaeological monitoring plan should be developed and provided to DAHP and interested Native American Tribes. An Inadvertent Discovery Plan should also be 12 Shoreline Substantial Development July 19, 2018 developed, to guide actions in the event that archaeological materials are encountered when the monitor is not on site." DAHP staff submitted a follow-up letter dated July 12, 2018 (See Attachment 8) to the City stating they have reviewed the report and concur with the recommendation that ground disturbance for the project be monitored by a professional archaeologist under an archaeological monitoring and inadvertent discovery plan (MDIP) reviewed by DAHP and the Tribes. DAHP also requested that an MDIP be prepared and submitted to DAHP and the Tribes for review prior to ground disturbance and monitoring. The Assessment report's and DAHP recommendations will be included as a condition of approval of this permit. 7. SEPA AND OTHER CITY APPROVALS An Environmental Checklist was submitted for the B-52 Memorial Park proposal (E16-0001) and a Notice of Decision was issued approving the proposal as a SEPA Planned Action on March 10, 2016. A Shoreline Tree Removal and Vegetation Clearing permit (L18-0030) was approved for this project on July 17, 2018. The applicant must obtain a building permit for park structures. 8. RECOMMENDATION Approval of the shoreline substantial development permit with the following condition: 1. Per the conclusions and recommendations of the Cultural Resource Assessment conducted for this project, the following actions are required: a. Develop and distribute an archaeological monitoring plan to DAHP and interested Native American Tribes prior to ground disturbance and monitoring. b.
