Summary of Proposed Action The proposal is a change to the Comprehensive Plan's Land Use Map and the Zoning Map from Low Density Residential to Commercial Light Industrial. II. General Information Project Name: Metro Training Facility Rezone Applicant: Gillian Zacharias, King County Metro Location: 12677 East Marginal Way S, APN 7345600766 Comp Plan Designation /Zoning: Split -zone: Commercial/Light Industrial (C/LI), Low Density Residential (LDR) The following information was considered as part of review of this application. 1. SEPA Checklist dated December 14, 2018 2. Endangered Species Act Screening Checklist dated December 5, 2018 3. Project and Decision Criteria Narrative provided December 13, 2018 III. Background/Proposal This application is part of the 2018-2019 annual docket for amendment of the Comprehensive Plan. The non -project proposal is a quasi-judicial change to the land use designation on the Tukwila Comprehensive Plan and Zoning Code maps for a 71,440 square foot lot from split -zoned Commercial/Light Industrial (C/LI) and Low Density Residential (LDR) to Commercial/Light Industrial. The subject site contains environmentally sensitive areas: Watercourse Type 2 stream in pipe, 100' buffer. IV. Review of the Environmental Checklist The following is a summary of the elements contained within the Environmental Checklist submitted for the proposed project. The numbers in the staff evaluation correspond to the numbers in the Tukwila City Hall • 6200 Southcenter Boulevard • Tukwila, WA 98188 • 206-433-1800 • Website: TukwilaWA.gov Environmental Checklist. If staff concurs with the applicant's response, this is so stated. If the response to an item in the checklist is found to be inadequate or clarification is needed, there is additional staff comment and evaluation. A. Background: 1.-7. Concur with checklist 8. According to the Washington Department of Ecology's Toxic Cleanup Sites inventory, the following site contains the following issues: "Soil containing residual lead and possibly petroleum hydrocarbons at concentrations exceeding Method A cleanup levels remain in localized areas. The residual lead in soil is believed to be associated with fill placed prior to Site development, not with the petroleum hydrocarbon release. The absence of benzene and lead in water samples collected in 2002 indicates the residual benzene and lead in soil have not impacted Site groundwater and pose no threat to human health or the environment, according to the consultant. Groundwater chemistry analytical data show that Site cleanup using groundwater extraction subsequent to the removal of petroleum -impacted soil was effective at removing residual hydrocarbons from groundwater, according to Camp Dresser & McKee Inc. (CDM), the environmental consultant. CDM indicated that remedial activities conducted at the Site have met the intent of the Model Toxic Control Act and, therefore, no further action is necessary for groundwater." Ecology issued a `No Further Action' (NFA) letter March 11, 2005 after a restrictive covenant was recorded with the county. 9-12. Concur with checklist B. Environmental Elements: 1. Earth: a—d Concur with checklist e This is a non -project proposal for a rezone of the subject property. A condition for approval of the rezone itself may include daylighting or improvement of the stream onsite which could potentially require grading and fill. If the proposal is approved, any new commercial/industrial use would be required to meet the environmental standards in place at the time of construction. A separate SEPA determination shall be provided during project proposal. f-h Concur with checklist 2. Air: a Applicant did not respond to "after" impacts. Emissions from project may increase due to increased intensity of use from LDR to C/LI. Employee and business traffic will likely affect air emissions in area. However, the current non -conforming use of the site as a truck terminal likely produces a greater amount of emissions within the area, and the removal of truck parking within the stream buffer area as a result of the site's non -conforming status being lost will reduce the amount of area available for vehicular use. b -c Concur with checklist E18-0016 Staff Report 2 3. Water: a (1-6) Concur with checklist b (1)-(2) Concur with checklist c (1)—(3) Concur with checklist d Surface water design and construction of any future project shall be per the King County Surface Water Design Manual as adopted by the City of Tukwila. All impacts associated with drainage will be mitigated as part of the construction permit. Low Impact Development standards have been adopted by the City of Tukwila and include such facilities as rain gardens, bio-retention, pervious pavement, etc. Best Management Practices must be followed to ensure that no construction debris enters stream. All impacts related to construction debris will be mitigated as part of the construction permit. 4. Plants: a-b Concur with checklist c All of Tukwila is mapped as threatened, accessible by the Washington Department of Fish & Wildlife Salmonscape. d Low Impact Development standards have been adopted by the City of Tukwila and include such facilities as rain gardens, bio-retention, pervious pavement, etc. Any new landscaping in permit will need to meet the requirements of Tukwila's Landscaping and Environmentally Sensitive Areas Ordinances. e Concur with checklist 5. Animals: a-b See comment below in ESA Screening Checklist c-e Concur with checklist 6. Energy and Natural Resources: a-c Concur with checklist 7. Environmental Health: a (1) Ecology issued a 'No Further Action' (NFA) letter March 11, 2005 after a restrictive covenant was recorded with the county. See comment for Background, (8), above. a (2)-(5) Concur with checklist b (1) Concur with checklist b (2) Any future construction project shall be subject to the City's noise ordinance and any construction related noise shall be subject to those regulations. Compliance with applicable local, state and federal noise regulations will mitigate any potential adverse noise impacts associated with the project. Any new uses allowed under C/LI zoning will generate additional vehicular traffic that will increase noise in immediate area. However, these will likely be significantly lower than the non -conforming truck terminal use currently permitted on the property. b (3) Concur with checklist 8. Land and Shoreline Use: E18-0016 Staff Report 3 a - c Concur with checklist d If the proposal is approved, any new commercial/industrial use would be required to meet the environmental standards in place at the time of construction. Current watercourse standards would require that any new use be setback out of the buffer unless a buffer reduction were approved. e-f Concur with checklist g - h The site does not contain a shoreline. i-m Concur with checklist 9. Housing: a-c Concur with checklist 10. Aesthetics: a- Concur with checklist b Development on a commercial light industrial site would require screening of related development from LDR zoned property on west. c. Concur with checklist 11. Light and Glare: a - d This is a non -project proposal and light and glare impacts from a future development project are not known. 12. Recreation: a—c Concur with checklist 13. Historic and Cultural Preservation: a-d Concur with checklist 14. Transportation: a-c Concur with checklist d Commercial development is typically required to make frontage improvements. This is a non -project proposal. Any future project would meet City of Tukwila parking standards. e-f This is a non -project proposal and number of trips cannot be quantified at this time. g-h Concur with checklist 15. Public Services: a-b Concur with checklist 16. Utilities: a-b Concur with checklist D. Supplemental for Non -Project Proposals E18-0016 Staff Report 4 1. The change in zoning from Low Density Residential to Commercial / Light Industrial would likely increase the number of vehicular trips and therefore emissions to air. However, these impacts will likely be significantly lower than the non -conforming truck terminal use currently permitted on the property. 2. Concur with checklist. Future development projects could include site designs that strive to preserve significant vegetation and incorporate native plants into the site's landscape plan, especially within the stream buffers along the western portion of the site. 3. Concur with checklist 4. The location of the watercourse makes "no impact" impossible. The existing condition is very disturbed. Redevelopment of the site as a commercial or light industrial use would require any development/use to be located outside of the stream buffer areas, or require administrative approval for a buffer reduction that automatically requires restoration work adjacent to the watercourse. The existing condition of a truck parking area built over the watercourse would be improved if the parking area is removed and the western portion of the site restored as a natural area for the watercourse. 5. The proposal could affect future land use in that other like properties would request a change in land use designation because of similar changed conditions. The redesignation/rezone of the site has the potential to justify the redesignation/rezone of other parcels in the vicinity or with similar environments. 6. Concur with checklist. 7. Concur with checklist, staff does not think that the proposed redesignation/rezone conflict with local, state or federal laws for the protection of the environment. IV. Review of Endangered Species Act Screening Checklist Question 1-4. Agree Question 5. Agree Question 6. Agree; however, Coho salmon, resident trout and other nonanadramous fish are potentially present per the City of Tukwila's 2013 Surface Water Comprehensive Plan. Part B - Project Specifics Part C - Project Specifics Water Quality Part D - Project Specifics: Flow Alteration and Fish Migration Part E - Project Specifies: Vegetation The above questions are not applicable. This request is a non -project action that does not involve construction. The request is for a change in the land use designation and zoning for the site. V. Public Comments E18-0016 Staff Report 5 Notice was sent to property owners and tenants within 500' of the site and agencies with jurisdiction. A Type 5 public meeting was held and three property owners attended. One residential property owner requested that a greater noise and visual buffer be provided on the west side of the property, to limit hours of operations to reasonable hours, to reduce the amount of visual impairment at the southeast corner of the lot for drivers pulling on to E Marginal Way S, and to limit street parking to 5 hours a day. Two residential property owners expressed concern via email about the past contamination of the site and potential impacts to the stream, as well the need for vegetated buffering around the site especially along the western portion adjacent to neighboring homes. They also expressed a desire to see the stream improved for fish habitat. No comments were received from the other agencies regarding the non -project proposal. VI. Conclusion The City Engineer has the authority and responsibility to direct traffic onto appropriate streets in the City. Chapter 11 of the Tukwila Municipal Code is enacted to regulate the use of the public right of way in the interest of public health, safety, and the protection of public infrastructure. Any potential need to modify street parking standards in the area as a result of future development will be analyzed as part of a project proposal through a future land use and/or development permit. Tukwila Title 18 requires that "On properties being developed or re -developed, or when stream crossings in public or private rights -of -way are being replaced, existing culverts that carry fish - bearing watercourses or those that could bear fish (based on the criteria in WAC 222-16-031, Washington Forest Practices Rules and Regulations), shall be upgraded to meet the standards in the WDFW manual "Design of Road Culverts for Fish Passage" (2003 or as updated) if technically feasible." King County Metro is exploring the technical feasibility of improving the stream culvert and restoring the stream buffer area as part of their comprehensive plan amendment proposal; any such requirement will be activated as part of a future development permit. Any development of the site will require additional analysis. This DNS is based on impacts identified within the environmental checklist, attachments, and the above "Final Staff Evaluation for Application No. E18-0016", and is supported by plans, policies, and regulations formally adopted by city of Tukwila for the exercise of substantive authority under SEPA to approve, condition, or deny proposed actions. The proposal can be found to not have a probable significant adverse impact on the environment and pursuant to WAC 197-11-340, a Determination of Nonsignificance (DNS) can be issued for this project.

The questions in this section will help determine if the ESA listings will impact your project. For more information on potential salmonid presence in your project area contact the Washington Department of Fish and Wildlife Habitat Biologist for your region, Washington Department of Fish and Wildlife or use the SalmonScape tool, WDFW SalmonScape. 1. Are ESA listed salmonids currently present in the watershed within which your project will be located? YesW No0 Please describe. The project is located within the Riverton Creek sub -basin of the Duwamish River watershed. Duwamish River is mapped as critical habitat for ESA -listed Puget Sound steelhead (Oncorhynchus mykiss) and Puget Sound chinook (Oncorhynchus tshawytscha). Both fish species are listed as Threatened. Riverton Creek is not mapped as critical habitat for any ESA -listed species. Puget Sound chinook and Puget Sound steelhead are modeled for Riverton Creek per WDFW's SalmonScape but their presence has not been documented. 2. Has there ever been an ESA listed salmonid stock present in this watershed? Yesn Non Uncertainty Please describe. See Question #1.

W:\APPLICATIONS - Land Use Apps & I landouts\CURRENT LAND USE APPLICATIONS\SEPA Environmental Review Application FINAL 5-9-16.doc SEPA ENVIRONMENTAL CHECKLIST Purpose of checklist: Governmental agencies use this checklist to help determine whether the environmental impacts of your proposal are significant. This information is also helpful to determine if available avoidance, minimization or compensatory mitigation measures will address the probable significant impacts or if an environmental impact statement will be prepared to further analyze the proposal. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Please answer each question accurately and carefully, to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use "not applicable" or "does not apply" only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decision - making process. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Instructions for Lead Agencies: Please adjust the format of this template as needed. Additional information may be necessary to evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made, the lead agency is responsible for the completeness and accuracy of the checklist and other supporting documents. Use of checklist for nonproject proposals: For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable parts of sections A and B plus the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). Please completely answer all questions that apply and note that the words "project," "applicant," and "property or site" should be read as "proposal," "proponent," and "affected geographic area," respectively. The lead agency may exclude (for non -projects) questions in Part B - Environmental Elements —that do not contribute meaningfully to the analysis of the proposal. A. Background FHELPl 1.

Do you have any plans for future additions, expansion, or further activity related to or connected with this proposal? If yes, explain. If efforts to rezone the parcel are successful, Metro plans to remodel the existing office/warehouse building for office and training purposes. Additional structures would be needed to fully utilize the site for Metro's needs. Metro has developed a conceptual plan for illustrative purposes to support the rezone. If the rezone is approved, Metro would look at expanding the structures to accommodate future training and office uses, and develop a site plan with proposed improvements as part of an application for Design Review. A separate SEPA checklist covering that development would be prepared to support the Design Review application. 8. List any environmental information you know about that has been prepared, or will be prepared, directly related to this proposal. Metro has identified sensitive areas on and adjacent to the subject parcel. A reconnaissance -level critical areas study has been completed and submitted as part of the application for a comprehensive plan and zoning map change (included in the rezone application packet as Exhibit G). The subject parcel underwent extensive soil and groundwater cleanup activities between 1999 and 2002 to remediate contamination resulting from a leaking underground storage tank (LUST). The Department of Ecology published its most recent review of post -cleanup site conditions at the subject parcel during 2016 (Washington Dept. of Ecology, Periodic Review Becker Trucking, aka C and D Wells Property, Facility Site ID#: 99622738, November 2016.)

Check the types of vegetation found on the site: X_deciduous tree: alder, maple, aspen, other _X_evergreen tree: fir, cedar, pine, other X_shrubs _X_grass pasture crop or grain Orchards, vineyards or other permanent crops. wet soil plants: cattail, buttercup, bullrush, skunk cabbage, other water plants: water lily, eelgrass, milfoil, other other types of vegetation b. What kind and amount of vegetation will be removed or altered? The rezone proposal is a non -project action. No vegetation will be removed or altered. c. List threatened and endangered species known to be on or near the site. No threatened or endangered plant species are known to be on or near the site. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: The rezone proposal is a non -project action. All vegetation currently on the parcel will be maintained. e. List all noxious weeds and invasive species known to be on or near the site. • Himalayan Blackberry • Creeping Buttercup (Ranuculus spectabilis) 5. Animals jhelpj a. List any birds and other animals which have been observed on or near the site or are known to be on or near the site. Examples include: birds: hawk, heron, eagle, songbirds, other: mammals: deer, bear, elk, beaver, other: fish: bass, salmon, trout, herring, shellfish, other -sculpin b. List any threatened and endangered species known to be on or near the site. No known threatened or endangered species are known to be on or near the site. Blue Nile Property Rezone;SEPA Checklist December 14, 2018 7 c. Is the site part of a migration route? If so, explain. The project vicinity is within the Pacific Flyway, an avian migratory corridor consisting of the western coastal areas of South, Central, and North America. Because of the urbanized nature of the project site, there are no existing native terrestrial migratory corridors. d. Proposed measures to preserve or enhance wildlife, if any: Because the proposed non -project action will have no effect on wildlife in the vicinity of the subject parcel, no measures to preserve or enhance wildlife are proposed. e. List any invasive animal species known to be on or near the site. None known 6. Energy and Natural Resources 'help] a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. The rezone proposal is a non -project action. No energy is needed. Future full build out of the site of the site for commercial or industrial uses is likely to result in greater energy use than a residential use. However, future construction of a single family residential use on the site seems unlikely given the adjacent Tight industrial uses allowed. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. The rezone proposal is a non -project action. There will not be any effects on solar use by adjacent properties because stream buffers and other development standards are likely to prevent future permitted uses from being built close to, or high enough to interfere with the use of solar power by adjacent uses. c. What kinds of energy conservation features are included in the plans of this? List other proposed measures to reduce or control energy impacts, if any: None proposed. 7. Environmental Health Jhelp] a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal? If so, describe. This rezone proposal is a non -project action. Existing contamination from leaking underground storage tanks was remediated in 1999 and is reviewed periodically. The most recent 2016 monitoring report concluded that there is no risk to human or environmental health by ingestion or contact. No site disturbance will occur as a result of the proposal. Blue Nile Property Rezone SEPA Checklist December 14, 2018 8 1) Describe any known or possible contamination at the site from present or past uses. Leaking underground storage tanks were remediated under the Model Toxics Control Act and the Voluntary Cleanup Program (codified in Chapter 173-340 WAC). Contamination from petroleum hydrocarbons, petroleum hydrocarbon constituents, and lead were found exceeding Method A cleanup levels. Contaminated soils were excavated where feasible and a groundwater treatment system was installed. Soils containing residual petroleum hydrocarbons and/or lead remain in localized areas. Monitoring reports conclude that there is no risk to human health or the environment. A restrictive covenant is recorded on the property to restrict activities that could cause ground disturbance. 2) Describe existing hazardous chemicals/conditions that might affect project development and design. This includes underground hazardous liquid and gas transmission pipelines located within the project area and in the vicinity. This rezone proposal is a non -project action. No existing hazardous chemicals or conditions might affect the proposal. Existing underground storage tanks are present on -site. Localized contamination is anticipated to exist as a result of past activities. There are no known underground transmission lines on this site. 3) Describe any toxic or hazardous chemicals that might be stored, used, or produced during the project's development or construction, or at any time during the operating life of the project. This rezone proposal is a non -project action. Toxic or hazardous chemicals will not be stored, used, or produced as a result of this proposal. 4) Describe special emergency services that might be required. This rezone proposal is a non -project action. Emergency services are not required. 5) Proposed measures to reduce or control environmental health hazards, if any: Because the proposed non -project action will not directly cause environmental health hazards, no measures to reduce or control environmental health hazards are proposed. Significant remediation was completed in 1999 and continues to be monitored. The Department of Ecology's most recent monitoring report concludes there is no risk to human health or the environment by ingestion or contact. b. Noise 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, other)? The rezone proposal is a non -project action. No noise in the area will affect the proposal. 2) What types and levels of noise would be created by or associated with the project on a short- term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. Blue Nile Property Rezone SEPA Checklist December 14, 2018 9 The rezone proposal is a non -project action. No additional noise will be directly created from the proposal. 3) Proposed measures to reduce or control noise impacts, if any: Since the proposed non -project action will not directly result in additional noise, no measures to reduce or control noise impacts are proposed. 8. Land and Shoreline Use Jhelpj a. What is the current use of the site and adjacent properties? Will the proposal affect current land uses on nearby or adjacent properties? If so, describe. The existing use of the subject parcel is classified as a truck terminal use with associated warehouse and office use. The site has been in continual operation as a trucking facility since before annexation into the City of Tukwila in 1989. The current improvements were developed in 1975 (City of Tukwila, 2016 Zoning verification Letter to Asmamaw Mijena, Blue Nile Turcking, LLC from Jack Pace, City of Tukwila). The rezone proposal is a non -project action and would result in rezoning the western half of the subject property consistent with the eastern half and would not immediately affect any adjacent properties. b. Has the project site been used as working farmlands or working forest lands? If so, describe. How much agricultural or forest land of long-term commercial significance will be converted to other uses as a result of the proposal, if any? If resource lands have not been designated, how many acres in farmland or forest land tax status will be converted to nonfarm or nonforest use? The history of site use prior to development as a truck terminal is unknown. 1) Will the proposal affect or be affected by surrounding working farm or forest land normal business operations, such as oversize equipment access, the application of pesticides, tilling, and harvesting? If so, how: There are no working farms or forest lands within the vicinity of the subject parcel. c. Describe any structures on the site. Structures on the subject parcel include an office/warehouse structure and a vehicle repair shop. d. Will any structures be demolished? If so, what? The rezone proposal is a non -project action.

Proposed measures to avoid or reduce displacement impacts, if any: None. I. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans, if any: The proposed non -project action would be consistent with the existing land use in the neighborhood in which parcels fronting on East Marginal Way have a Commercial/Light Industrial zoning classification. m. Proposed measures to reduce or control impacts to agricultural and forest lands of long-term commercial significance, if any: None. 9. Housing Jhelpl a. Approximately how many units would be provided, if any? Indicate whether high, middle, or low- income housing. The rezone proposal is a non -project action. No housing is proposed. Housing is not a permitted use in the C/LI zoning district. b. Approximately how many units, if any, would be eliminated? Indicate whether high, middle, or low-income housing. Blue Nile Property Rezone SEPA Checklist December 14, 2018 11 The rezone proposal is a non -project action. The site is developed as a trucking terminal with a warehouse and office space. No housing would be eliminated. c. Proposed measures to reduce or control housing impacts, if any: None. 10. Aesthetics jhelpl a. What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterior building material(s) proposed? The rezone proposal is a non -project action. No structures are proposed. The C/LI district would allow structures up to four stories or 45 feet in height (subject to design review), while the existing residential zone would allow 30 feet in height. b. What views in the immediate vicinity would be altered or obstructed? The rezone proposal is a non -project action. No views would be altered or obstructed. d. Proposed measures to reduce or control aesthetic impacts, if any: None proposed. 11. Light and Glare jhelpl a. What type of light or glare will the proposal produce? What time of day would it mainly occur? The rezone proposal is a non -project action and will not result in Tight or glare. b. Could light or glare from the finished project be a safety hazard or interfere with views? The rezone proposal is a non -project action and will not result in light or glare. The proposal will not create safety hazards or interfere with views. c. What existing off -site sources of light or glare may affect your proposal? Off -site sources of Tight or glare would not affect the rezone proposal. d. Proposed measures to reduce or control light and glare impacts, if any: None. 12. Recreation jhelpl a. What designated and informal recreational opportunities are in the immediate vicinity? Bike lanes are located on East Marginal Way South, adjacent to the subject parcel. Riverton Park is located approximately 1,100 feet south of the subject parcel. Blue Nile Property Rezone SEPA Checklist December 14, 2018 12 • b. Would the proposed project displace any existing recreational uses? If so, describe. The proposed non -project action will not displace any existing recreational uses. c. Proposed measures to reduce or control impacts on recreation, including recreation opportunities to be provided by the project or applicant, if any: None. 13. Historic and cultural preservation f helpj a. Are there any buildings, structures, or sites, located on or near the site that are over 45 years old listed in or eligible for listing in national, state, or local preservation registers ? If so, specifically describe. There are no buildings, structures, or sites on or in the immediate vicinity of the site that are over 45 years old. b. Are there any landmarks, features, or other evidence of Indian or historic use or occupation? This may include human burials or old cemeteries. Are there any material evidence, artifacts, or areas of cultural importance on or near the site? Please list any professional studies conducted at the site to identify such resources. Cultural Resources in the Project Vicinity KING 7041 is the ethnographically recorded placename sEelac for the hill that formerly existed adjacent to the subject property. The placename is associated with the mythological story of the North Wind and is translated by Waterman (1922) as "dirty face." The hill was entirely removed by quarrying in the historic period. There are no other recorded, reported or suspected cultural resources in the project vicinity. Cultural Resources within 1/ Mile of the Project 45-KI-431 is the Allentown Shellmidden Site. This large prehistoric site is located across the river from the project and is dated to 500 years ago. 45-KI-703 is the Duwamish Gardens Site. This large prehistoric site is dated to between 900 and 500 years ago. There are no other recorded, reported or suspected cultural resources within 'A mile of the project (Minichillo, 2018 Cultural Resources Screening — Blue Nile Holdings) c. Describe the methods used to assess the potential impacts to cultural and historic resources on or near the project site. Examples include consultation with tribes and the department of archeology and historic preservation, archaeological surveys, historic maps, GIS data, etc. A cultural resources screening was conducted by Mr. Tom Minichillo, PhD, King County Department of Transportation Archaeologist. d. Proposed measures to avoid, minimize, or compensate for loss, changes to, and disturbance to resources. Please include plans for the above and any permits that may be required. The rezone proposal is a non -project action. Impacts to cultural and historic resources are not anticipated and no mitigation measures are proposed. Blue Nile Property Rezone SEPA Checklist December 14, 2018 13 14. Transportation jhelol a. Identify public streets and highways serving the site or affected geographic area and describe proposed access to the existing street system. Show on site plans, if any. The subject parcel is bounded on the east by East Marginal Way South and on the south by South 128th Street. The subject parcel is accessed by either roadway. b. Is the site or affected geographic area currently served by public transit? If so, generally describe. If not, what is the approximate distance to the nearest transit stop? The subject parcel is served by King County Metro Transit route 154. A southbound stop is located adjacent to the subject parcel on East Marginal Way South. A northbound stop is located across the street from the subject parcel. c. How many additional parking spaces would the completed project or non -project proposal have? How many would the project or proposal eliminate? The rezone proposal is a non -project action. No changes to parking are proposed. d. Will the proposal require any new or improvements to existing roads, streets, pedestrian, bicycle or state transportation facilities, not including driveways? If so, generally describe (indicate whether public or private). The rezone proposal is a non -project action. New or improvements to existing transportation facilities are not needed. e. Will the project or proposal use (or occur in the immediate vicinity of) water, rail, or air transportation? If so, generally describe. The non -project rezone proposal will not use water, air, or rail transportation. f. How many vehicular trips per day would be generated by the completed project or proposal? If known, indicate when peak volumes would occur and what percentage of the volume would be trucks (such as commercial and nonpassenger vehicles).

Supplemental sheet for nonproject actions JHELPI (IT IS NOT NECESSARY to use this sheet for project actions) Because these questions are very general, it may be helpful to read them in conjunction with the list of the elements of the environment. When answering these questions, be aware of the extent the proposal, or the types of activities likely to result from the proposal, would affect the item at a greater intensity or at a faster rate than if the proposal were not implemented. Respond briefly and in general terms. 1. How would the proposal be likely to increase discharge to water; emissions to air; production, storage, or release of toxic or hazardous substances; or production of noise? The proposed change to the City of Tukwila Comprehensive Plan and Zoning Map for the subject parcel will not result in increasing discharge to water; emissions to air; production, storage, or release of toxic or hazardous substances; or production of noise. The rezone could potentially incentivize redevelopment of the property that would lead to a change in use from a trucking terminal to a different commercial or light industrial use. Several of the land uses that are allowed under the Commercial/Light Industrial Land Use Designation would potentially be equally or more impactful to the adjacent Low Density Residential neighborhood than the current use, would be subject to Tukwila Municipal Code 18.64, Conditional Use Permits. Additionally, environmentally sensitive areas restrictions placed on any redevelopment will result in a greater separation between site activities, adjacent landowners and sensitive areas. Given code restrictions , the need for administrative review, and the size, location,and characteristics of the property, it is anticipated that any changes in use would not increase discharges to water; emissions to air; production, storage, or release of toxic or hazardous substances; or production of noise. Metro would propose a change of use for the property, subject to a separate SEPA and land use review that would involve remodeling the existing office/warehouse structure and possibly adding additional office space to accommodate future training and office uses. These changes to the site use would likely reduce the likelihood of discharge to water; emissions to air; production, storage, or release of toxic or hazardous substances; or production of noise. Proposed measures to avoid or reduce such increases are: None required or needed. The Tukwila Municipal Code requires performance standards for the Commercial/Light Industrial zone, including: adherence to standards adopted by the Puget Sound Air Pollution Control Agency for odor, dust, smoke, and airborn pollutants; noise standards adopted in Chapter 8.22 TMC; and State and Federal standards for water quality and hazardous materials. Production, storage, or release of toxic or hazardous substances is not allowed in the C/LI zone. The City of Tukwila adopted the 2016 King County Surface Water Design Manual, which requires any new development to comply with specific stormwater detention and treatment requirements. Review under the State Environmental Policy Act for project -specific actions provides substantive authority to mitigate potential adverse environmental impacts. 2. How would the proposal be likely to affect plants, animals, fish, or marine life? Blue Nile Property Rezone SEPA Checklist December 14, 2018 16 The proposed non -project action will not affect plants, animals, fish, or marine life. The proposal will not lead to any future development that will adversely affect plants, animals, fish, or marine life. Any change in land use at the site would require compliance with Tukwila Municipal Code 18.45 which will impose stream buffers and setback requirements, currently 100 feet plus 15 feet, respectively. It is likely that stream buffer requirements could increase in the near future. This will limit the amount of developable land on the subject parcel and create a vegetated buffer between future land uses on the site and the adjacent residential neighborhood. Proposed measures to protect or conserve plants, animals, fish, or marine life are: None required or needed. The site is almost entirely paved. The C/LI zone requires any development project to provide landscaping around the perimeter of the site that will improve conditions for plants, animals, fish, and/or marine life. 3. How would the proposal be likely to deplete energy or natural resources? The proposed non -project action will not deplete energy or natural resources. The proposal will not lead to any future development that will deplete energy or natural resources above and beyond other conventional commercial or light industrial development. Proposed measures to protect or conserve energy and natural resources are: None required or needed. 4. How would the proposal be likely to use or affect environmentally sensitive areas or areas designated (or eligible or under study) for governmental protection; such as parks, wilderness, wild and scenic rivers, threatened or endangered species habitat, historic or cultural sites, wetlands, floodplains, or prime farmlands? The proposed non -project action will not affect environmentally sensitive areas or areas designated for governmental protection. The project site is currently used for commercial/light industrial purposes, and rezoning the western portion of parcel no. 07345600766 would have no noticeable effects to the existing low functioning water course and wetland/stream buffers on site or adjacent to this area. Proposed measures to protect such resources or to avoid or reduce impacts are: None required or needed. The City of Tukwila has adopted a Critical Areas Ordinance codified as Chapter 18.45 TMC. The CAO addresses development in or near environmentally sensitive areas. The only environmentally sensitive area present is the east fork of Riverton Creek, which is undergrounded in a pipe. No other sensitive areas or cultural resources are mapped on or in the immediate vicinity of the site. 5. How would the proposal be likely to affect land and shoreline use, including whether it would allow or encourage land or shoreline uses incompatible with existing plans? The proposed non -project action will not affect the existing land use. The proposal may incentivize redevelopment of the parcel that could lead to a change in use from a trucking terminal to a different commercial or light industrial land use. If redevelopment were proposed with the zone change, the Blue Nile Property Rezone SEPA Checklist December 14, 2018 17 development would be subject to current standards, which the existing development appears to not meet. Therefore there would be a net benefit. This is consistent with the requested comprehensive plan and zoning map amendment. The subject property is not located within the 200-foot shoreline jurisdiction. Proposed measures to avoid or reduce shoreline and land use impacts are: None required or needed. Any change in land use would be consistent with the C/LI zoning designation, and consistent with the character of the property and its urbanized context. 6. How would the proposal be likely to increase demands on transportation or public services and utilities? The proposed non -project action will not directly increase demands on transportation or public services and utilities. The proposal may incentivize redevelopment of the property at some point in the future. For uses explicitly allowed in the C/LI zone, no additional studies related to transportation or public services and utilities are needed. Uses requiring a conditional use permit or similar land use entitlement will be required to provide studies such as a transportation impact analysis at the time of permitting. Such studies would determine if there are increased demands on transportation or public services and utilities. Proposed measures to reduce or respond to such demand(s) are: None required or needed. Demands for transportation or public services and utilities are anticipated to remain the same under any redevelopment scenario involve uses permitted outright in the C/LI zone. Any uses allowed with a conditional use permit or similar land use entitlement would have increased demands on transportation or public services and utilities evaluated and addressed during permit review. 7. Identify, if possible, whether the proposal may conflict with local, state, or federal laws or requirements for the protection of the environment. This proposal will not conflict with any known local, state, or federal laws or requirements for the protection of the environment. Blue Nile Property Rezone SEPA Checklist December 14, 2018 18 Otak Technical Memorandum To: Gillian Zacharias and Tom Paine, King County Metro Transit From: Jeff Gray, Senior Wetland Biologist Stephanie Modjeski, Biologist Copies: Otak: Chad Weiser, Cristina Haworth Date: December 10, 2018 Subject: Critical Areas Assessment and Proposed Rezoning Review: 12677 E Marginal Way S Project NO.: 32870.E Introduction King County's Department of Transportation (Metro Transit) requested Otak, Inc. (Otak) to identify and characterize critical areas at 12677 E Marginal Way S (Parcels #7345600766 and #73456100685) to support the potential acquisition of the properties. Metro Transit is also planning to submit a rezoning request to the City of Tukwila for parcel #7345600766. This technical memorandum presents the findings of the reconnaissance level critical areas study and Tukwila Municipal Code (TMC) review. The environmental impacts of the proposed rezoning are also assessed to support the State Environmental Policy Act (SEPA) compliance process for the non -project action by the City of Tukwila. Critical areas reviewed for this memorandum include wetlands, watercourses, and fish and wildlife habitat conservation areas (FWHCAs) as regulated by TMC Chapter 18.45 (Environmentally Sensitive Areas). The two parcels, herein referred to as the project site, are located at the corner of S 128th Street and E Marginal Way in the City of Tukwila, King County, Washington (Figure 1 — Vicinity Map). Otak biologists completed a field survey to identify and characterize critical areas and their buffers on the project site on November 29, 2018. Site photographs and figures are included with this memorandum. Methods Methods to complete the reconnaissance level critical areas assessment included reviewing published environmental documentation and completing a field visit to investigate the presence and extent of watercourses, wetlands, FWHCAs, and associated buffers on site. The presence of wetlands was investigated using the three -parameter approach detailed in the Corps of Engineers Wetlands Delineation Manual (USACE 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (USACE 2010). Wetland boundaries were estimated for the purpose of the reconnaissance -level field survey. Wetland habitats were classified according to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin, et al. 1979), and the hydrogeomorphic (HGM) wetland classification as adopted by Hruby (2004). Wetland functions were rated using the 2004 Washington State Wetland Rating System for Western Washington (Hruby 2004), and preliminary wetland buffer widths were determined by wetland rating per TMC 18.45.080 (Wetlands Designations, Ratings and Buffers).Ae,9 i �i DEC Gommument Develop k1project1328001328701projectdocs132870b bluenile criticalareaslca memoltechnical memorandum_2018-1210.docx 2731 Wetmore Avenue, Suite 300 Everett, WA 98201 • Phone (425)493-5221 otak.com Page 2 Critical Areas Assessment and Proposed Rezoning Review December 10, 2018 Watercourses were identified based on indicators of flowing water and an ordinary high-water mark (OHWM), and classified according to TMC 18.45.100 (Watercourses Designations, Ratings and Buffers). Identification of OHWM was based on the evaluation of stream physical characteristics, such as: the natural line impressed on the bank, change in sediment and vegetation characteristics, wracking, erosion/scour, and silt deposits. The presence of FWHCAs in or near the project site was assessed by visual observation during the field visit in combination with reviewing available published information. Background Review Background information reviewed prior to completing the site investigation included the following resources: • City of Tukwila Comprehensive Plan & Zoning Map (City of Tukwila 2015) • City of Tukwila Sensitive Areas Map (City of Tukwila 2015a) • King County iMap (King County 2018) • U.S. Fish and Wildlife (USFWS) —National Wetland Inventory (NWI) (USFWS 2018) • Washington Department of Natural Resources (DNR) — Forest Practices Application Mapping Tool (WDNR 2018) • WDFW — Priority Habitats and Species (PHS) on the Web (WDFW 2018) • Washington Department of Fish and Wildlife (WDFW) — SalmonScape (WDFW 2018a) The City of Tukwila Sensitive Areas Map (attached) identifies one Type 2 stream within the project site, herein referred to as the east branch of Riverton Creek. The east branch of Riverton Creek is mapped as an open channel west and north of the project site boundaries and piped on site. The stream is piped downstream of the project site along E Marginal Way S from approximately S 126th Street to State Route (SR) 599. Type 2 streams are defined as Type F (fish) watercourses per TMC 18.45.100 and have a 100-foot-wide buffer. 100-foot-wide stream buffers are shown extending from the open portions of the stream channel onto the project site. No other wetlands or watercourses are mapped on or near the project site by King County, USFWS, WDNR or WDFW. WDNR and WDFW map the east branch of Riverton Creek up to SR 599 north of S 120th Place, but no watercourse is shown south of that intersection. WDNR types the east branch of Riverton Creek as a Type N (non -fish) watercourse. The west branch of Riverton Creek is shown flowing parallel to SR 99 approximately 1,000 feet west of the project site. The west branch of Riverton Creek is Type F (fish) per WDNR and a Type 2 watercourse per the City of Tukwila's Sensitive Areas Map. Per the City's Sensitive Areas Map, no FWHCAs are mapped on or within the vicinity of the project site. No areas of geologic instability or abandoned coal mines, two additional types of regulated environmentally sensitive areas, are mapped on the project site as well. Findings Site Description The project site is located within amongst residential and commercial properties. Single-family residential neighborhoods are generally located west of the project site, and commercial properties are located to the north and south along E Marginal Way S. The two parcels combined are approximately 1.85 acres in size and currently used to store small motor vehicles and semi -truck trailers in a partially paved storage yard operated by the Blue Nile Trucking. Commercial buildings are in the southeast corner. The western and northern edges of the project site are bordered by coniferous trees with herbaceous plants in the understory and a chain -link fence. Patches of invasive, non-native Himalayan blackberry (Rubus armeniacus) are also located along the fence lines. In general, k:lproject1328001328701projectdocs132870b bluenile_criticalareaslca memoltechnical memorandum_2018-1210.docx Page 3 Critical Areas Assessment and Proposed Rezoning Review December 10, 2018 the western half of the storage yard is gravel and the eastern half is paved. A catch basin is present within the gravel lot in the northwest corner of Parcel #7345600766 that provides access to a piped stream underground. Watercourses The east branch of Riverton Creek was identified on the project site. The stream emanates from a culvert immediately west of the chain -link fence bordering the western edge of parcel #7345600766. The stream has an approximately 7-foot wide bank full width and flows for approximately 25 feet through a rock -lined channel before entering a 36-inch corrugated metal pipe culvert at the edge of the gravel storage yard. Concrete chunks and other debris was observed in the channel. The stream is piped approximately 135 feet to the northeast beneath the gravel lot and turns north for approximately 60 feet before discharging at the northern edge of the property into an open channel. The east branch of Riverton Creek is a Type 2 (fish) watercourse per TMC 18.45.100 (Watercourse Designations, Ratings, and Buffers). Open, Type 2 watercourses have a standard 100-foot-wide buffer per TMC 18.45.100.C. The TMC does not state explicitly whether piped portions of streams have standard buffers or not, but the piped stream on site does not appear to have a standard buffer width per the City's Sensitive Areas Map. All commercial and industrial buildings are required to have a 15-foot set -back and all other development shall have a 10-foot set -back from the buffer's edge. Buffer conditions are degraded and low functioning due to the existing gravel and paved lot and minimal vegetation cover. The stream buffer overlaps the gravel lot as shown on Figure 2 (Critical Areas). Per DNR's typing methodology, watercourses with perennial flows that have defined channel two feet or greater within the bank full width and have a gradient of 16 percent or less are considered Type F streams unless the stream has been proven not to contain fish using methods described in Forest Practices Board Manual Section 13. Due to the perennially flowing water, channel characteristics, and approximate three percent grade downstream of 37th Avenue South and through the project site, the east branch of Riverton Creek is classified a Type 2 (Fish) watercourse. Wetlands Two riverine wetlands (Wetlands A and B) were identified off -site along the east branch of Riverton Creek. Estimated wetland boundaries are shown on Figure 2 (Critical Areas). Wetland A is located north of the subject property between the northern property edge and S 126th Street and is situated between residential and commercial land uses. Wetland A is classified as palustrine forested habitat under the Cowardin classification system, and as riverine under the HGM system as adopted by Hruby (2004). Dominant vegetation in Wetland A includes black cottonwood (Populus balsamifera spp. trichocarpa), Pacific willow (Salix lucida), Sitka willow (Salix sitchensis), salmonberry (Rubus spectabilis), and creeping buttercup (Ranunculus repens). Wetland B is located west of the subject property within the back yard of the abutting residential property. Wetland B is classified as palustrine emergent habitat under the Coward classification system, and as riverine under the HGM system as adopted by Hruby (2004). Dominant vegetation in Wetland B includes broadleaved cattail (Typha latifolia) and creeping buttercup. Wetlands A and B were preliminarily classified as Category III wetlands. Both wetlands have a standard buffer width of 80 feet per TMC 18.45.080.D. Wetland buffers on the subject property are superseded by the 100-foot- wide stream buffer as shown on Figure 2 (Critical Areas). k1project1328001328701projectdocs132870b bluenile_criticalareaslca memoltechnical memorandum_2018-1210.docx Page 4 Critical Areas Assessment and Proposed Rezoning Review December 10, 2018 Proposed Zoning Changes and Code Review The following section includes an assessment of the potential environmental impacts of the proposed rezoning relative to TMC Chapter 18.45 (Environmentally Sensitive Areas). This assessment is intended to support the SEPA compliance process for the proposed rezoning. An Endangered Species Act Screening Checklist is also enclosed with this memorandum and is expected to accompany the non -project action SEPA checklist for the proposed rezoning. Proposed Rezoning Parcel #7345600685 and the eastern half of Parcel #7345600766 is zoned Commercial Light Industrial (CLI). The western half of parcel #7345600766 is zoned Low Density Residential (Figure 3 — Existing Zoning). Metro Transit proposes to re -zone Parcel #7345600766 entirely as CLI for consistency with the existing and proposed future land use. Environmental Impacts and Redevelopment Opportunities Redevelopment with either residential or commercial/light industrial uses could create substantial opportunities for environmental improvements and enhancements of ecological functions that are currently degraded. The project site is currently used for commercial/light industrial purposes, and re -zoning the western portion of parcel #7345600766 would have no noticeable effects to the existing low functioning watercourse and wetland/stream buffers on site or adjacent to this area due to the existing legal, non -conforming use. Under new development proposals, existing legal and nonconforming land uses within the current wetland/stream buffer areas could be removed, and new developments would be required to conform to the provisions of TMC Chapter 18.45 (Environmentally Sensitive Areas) that limit or do not allow development within critical areas or critical area buffers. For example, standard watercourse buffers may be reduced only where the buffer is significantly degraded due to existing development within the prescribed buffer, provided that the existing buffer is enhanced in accordance with an approved buffer enhancement plan (TMC 18.45.100.E). The standard buffer width cannot be reduced by more than 50 percent under any land use proposal. Per TMC 18.45.100.E, any buffer reduction proposal must demonstrate that it will not result in direct, indirect or long-term adverse impacts to watercourses, and that an on - site buffer enhancement plan is prepared. Due to the currently degraded buffer conditions on site, a buffer reduction request would likely be justified and approved under any future development proposal. Allowed development or other activities within critical areas and critical area buffers —and any potential exemptions for such alterations —would pertain to both LDR and CLI zoned lands. The City of Tukwila's environmentally sensitive areas code will pertain to all zoning areas and does not differ between LDR and CLI land uses. Redevelopment may provide opportunities for mitigation and/or wetland and stream buffer enhancement in the disturbed buffer areas using best available science, with an anticipated improvement of ecological functions provided by the critical area and its buffer. Any proposed development plan within watercourse buffers would need to include a buffer mitigation plan per TMC 18.45.110 (Watercourse Alterations and Mitigation) and buffers would need to be restored to an enhanced state (TMC 18.45.110.D.2). Because all land uses and proposed development must comply with the City of Tukwila's environmentally sensitive areas code, significant impacts to environmentally sensitive areas and their buffers are not expected to result from the proposed zoning change. k:Iproject1328001328701projectdocs132870b bluenile criticalareaslca memoltechnical memorandum_2018-1210.docx Page 5 Critical Areas Assessment and Proposed Rezoning Review December 10, 2018 References City of Tukwila (City). 2015.

We under- stand that the existing commercial buildings will be demolished prior to construction of the new Facility. Construction of the Facility consists of the following features: • Vehicle Maintenance (VM) Building located at the southwest corner of the site. This building is a proposed one-story, at -grade structure that will have maintenance pits used to service buses. We understand that the maintenance pits will extend up to seven feet below exist grade. • Operation (OPS) building located at the northeast corner of the site where a storm - water pond currently exists. This building is a proposed one-story, at grade structure. • Infiltration facilities along the east and west boundaries of the site. • Paving over most of the site including existing building locations. 1.2 Scope of Services This scope of services was authorized under work order no. 4 under contract E00455E16 is- sued by Tetra Tech, Inc effective July 9, 2018.

This report should not be used for other purposes without Clarity Engineering's review. This report is an informational document and is not to be used for construction contractual purposes. Clarity Engineering should be retained to review the applicability of assumptions, conclu- sions, and recommendations of this report if any of the following occurs: • Conditions at or adjacent to the site change due to natural forces or human activity. • The basis of this report has changed or is no longer representative or accurate. • Project details or schedules change or new information about the project or site be- comes available. • If the site ownership or land use has changed. • Regulations or laws change. 1.5 Limitations This report for the King County South Interim Base was prepared in accordance with local generally accepted engineering principles, practices and standards. No warranty is ex- pressed or implied. The findings and recommendations contained in this report are based upon the services you requested and approved. Geotechnical engineering requires the application of professional judgment, as no study can completely quantify subsurface conditions. Any interpretations of subsurface conditions in this report are based on our analyses, experience, and judgment. There is no warranty that these subsurface conditions occur anywhere on the site except at the exact location and exact Project No: 107 3 KC Interim South Base - Geotech Report (DRAFT).docx DRAFT . Clarity Engineering LLC time when and where explorations and field tests were conducted. Groundwater levels can be especially sensitive to seasonal and other changes. Clarity Engineering is not responsible for interpretations others may make using this report. The conclusions and recommendations in this report assume that field explorations and tests, and our interpretations accurately portray and represent subsurface conditions at the site. If, during excavation and/ or construction significantly different subsurface conditions are en- countered from that described in this report, our firm should be immediately notified and retained to review these conditions and, if necessary, revise our recommendations. Unantic- ipated soil conditions are commonly encountered during excavation and construction and cannot be fully anticipated by widely spaced subsurface sampling locations and testing in- tervals. The owner should be prepared to accommodate potential extra costs through the development of a contingency fund. If there is a significant lapse of time between our report submittal and the start of construc- tion, we should be retained to review and verify site conditions. Clarity Engineering cannot be responsible for any deviation from the intent of this report including, but not limited to the nature of the project, the construction timetable, and any construction methods discussed in this report. The recommendations contained in this report are not intended to direct the contractor's methods, techniques, sequences or procedures, ex- cept as may be specifically described in the report. Clarity Engineering will not be responsi- ble or liable for any construction, scheduling, or safety activity on this site.

The current facilities located on the site consist of a multilevel parking structure, a large one- story commercial building, a one-story addition to the commercial building, a stormwater pond, and paved parking areas and throughways. Based on historic topographic maps (Wal- dron 1962) and geology and mineral resource documents (Cole and Fraser, 1969), the site was once a rock outcrop consisting of basalt and sandstone. The Riverton quarry was formed at the site in 1930 to mine the basalt. An aerial photograph of the site during quarry operations is shown in Figure 3. 1 Figure 3 - Aerial photograph of site during quarry operations According to these documents, the quarry consisted of many working levels with the lowest occurring along the eastern boundary near the highway. The quarry was apparently back - filled however the methods and composition of that backfill is unknown except where the historic explorations and the explorations performed for this study sampled the fill. 2.2 Subsurface Explorations We performed three mud -rotary borings and one hollow -stem auger boring drilled for the current project to evaluate the subsurface conditions at the locations of proposed develop- ment. The locations of these borings are shown on Figure 2 - Site and Exploration Plan. De- tailed information on methods used for the subsurface explorations and boring logs are pre- sented in Appendix A. Laboratory test methods and results are presented in Appendix B. In addition, we have reviewed documents of historic explorations performed by others for Project No: 107 5 KC Interim South Base - Geotech Report (DRAFT).docx DRAFT Clarity Engineering LLC previous development of this site and the King County South Base facility to the north. His- toric boring logs prepared for the development of the existing parking garage structure are presented in Appendix C. Note that a site map and some pages of the boring logs were miss- ing from this document. Boring and test pit logs and site map that were prepared for the original King County South Base facility are presented in Appendix D. For this study, we measured groundwater piezometric levels using vibrating wire piezome- ters installed in two boreholes and observed indications of groundwater in a third borehole. Groundwater level observations are also available from the historic explorations completed by others. All observations indicate that groundwater levels vary across the site from ap- proximately 4 to 20 feet below existing ground surface. The groundwater levels are likely influenced by rainfall, the water level in the Duwamish River, the geometry of the quarry excavations, groundwater flow from the surrounding area and slope at the south end of the site, and environmental factors. 2.3 Interpreted Subsurface Conditions Our understanding of the subsurface conditions of the project site are based observations of conditions encountered in our explorations, our review of historic explorations, and our un- derstanding of the historic quarry activity at the project site. Given the variability of subsur- face conditions we observed at the site and for purposes of this design report we have as- sumed different subsurface conditions across the site. 2.3.1 VM Building At the southwest corner of the site where the VM building is proposed we observed a four to five -inch layer of asphalt pavement over approximately 1 to 2 feet of fill. Beneath the fill we encountered dense to very dense sand that appears to be native soils down to the maximum explored depth of 31.5 feet below ground surface (bgs). Some of the sand was slightly ce- mented indicating that it likely is or was derived from a weathered sandstone. Groundwater observations were obscured by the exploration methods used near the planned VM Building, however groundwater piezometric measurements were made by vibrating wire piezometer installed in exploration MW-4. Measurements made during the month of September indicate a piezometric level four feet below the ground surface. Moisture contents of samples collected from explorations B-3 and MW-4 appear consistent with this piezometric Project No: 107 6 KC Interim South Base - Geotech Report (DRAFT).docx DRAFT Clarity Engineering LLC surface. These groundwater measurements were made during the dry season; we expect that wet season groundwater levels could be higher by approximately two to three feet. 2.3.2 OPS Building At the northeast corner of the site near the existing detention pond and the planned OPS building, we observed a four to five -inch layer of asphalt pavement over approximately 1 to 2 feet of base gravel fill. Beneath the gravel base we observed silt, sand, and gravel fill to a depth of about 15 feet bgs underlain by a medium dense to dense sandy silt fill to a depth of 27 feet bgs. Based on groundwater levels, it is possible that the sandy silt was placed in submerged conditions. Below 27 feet bgs we encountered a hard, blue -gray, sandstone down to the maximum explored depth of 30 feet bgs. Groundwater was observed in boring B-3 at depths of 12 to 14 feet bgs. Measurements gath- ered from the VWP instrument installed in exploration MW-1, indicates a piezometric surface 12 feet bgs. Moisture contents of samples collected from these two explorations appear con- sistent with this piezometric surface. Explorations completed for the existing parking structure indicate the shallowest depth of groundwater encountered at that time was nine feet bgs with localized seepage at shallower depths. Explorations completed for the King County South Base facility to the north of the site measured groundwater fluctuations of four to six feet. This seasonal fluctuation should be considered likely for the OPS building and nearby facilities. 2.4 Additional Explorations and Groundwater Level Monitoring Additional test pits are scheduled to be performed in November 2018 and groundwater pie- zometric levels will continue to be monitored through May 2019 to assess seasonal ground- water levels and infiltration rates at the site. Results of the additional explorations and groundwater monitoring will be incorporated into the final version of this report. 3 EARTHQUAKE ENGINEERING HAZARD 3.1 Liquefaction and Lateral Spread We evaluated the liquefaction potential of soils within the project area using the simplified method of Boulanger and Idriss 2014. Earthquake input parameters used in our analyses Project No: 107 7 KC Interim South Base - Geotech Report (DRAFT).docx DRAFT Clarity Engineering LLC were determined using the 2008 United States Geological Survey (USGS). seismic hazard model for a recurrence interval of 2,475 years (Petersen et al, 2008). We used a design earth- quake magnitude of 7.1 and peak ground acceleration (PGA) equal to 0.63g. Based on our analyses, the site soils are not susceptible to liquefaction. Given that the site soils are not liquefiable, the risk of liquefaction -induced settlement and lateral spreading for this site is low. 3.2 Seismic Design Information Based on our interpretation of the existing subsurface data, the site can be classified as a Site Class C for structures. Site Class C seismic parameters for this site that should be used to construct a code -based spectrum are shown in Table 1 below. Table 1: IBC 2015 Seismic Design Parameters IBS 2015 Seismic Parameter Value Site Class Designation C Short Period SRA, Ss, Site Class B 1.51g Long Period SRA, Si, Site Class B 0.57g Seismic Coefficient, FA 1.0 Seismic Coefficient, Fv 1.3 Short Period SRA, Ss, Site Class C 1.51g Long Period SRA, Sl, Site Class C 0.74g SRA = Spectral Response Acceleration Source: USGS US Seismic Design Maps 4 SHALLOW FOUNDATIONS In our opinion, the VM and OPS buildings and slabs -on -grade can be supported by shallow foundations. However, given the varying subsurface conditions, differing preparation of subgrade soils and allowable bearing pressures are required. The VM building foundations can be placed on dense, in -situ soils assumed to be no more than 2 feet below the bottom of the foundations. The OPS building foundations can be placed on structural fill that will need to be placed to fill the excavation created by the demolition of the existing stormwater deten- tion pond. Project No: 107 8 KC Interim South Base - Geotech Report (DRAFT).docx DRAFT 4.1 Bearing Pressures and Footing Depths Clarity Engineering LLC Sliallow, square and strip footing foundations for the two buildings can be designed for the allowable bearing pressures in Table 2, provided the subgrade preparation recommendations in Section 8.1, Subgrade Preparation are followed. Table 2: Shallow Foundation - Allowable Bearing Pressures Location Allowable Bearing Foundation Pressure Soils VM Building OPS Building ksf = kips per square foot 8 ksf 3 ksf Dense, In -Situ Sand Structural Fill A temporary, one-third increase in bearing pressure is allowed for wind and earthquake loading cases. Footing widths should be a minimum of 18-inches. The VM Building foundations can be founded on the dense, native sand encountered in bor- ings B-3 and MW-4 at 2 feet bgs. The footings should be founded at the lower elevation as determined from the following criteria: • two feet below finished grade, • the bottom elevation of the demolished existing communications building footings, • the lowest elevation of soil disturbed by demolition activities. If the above criteria are too costly or onerous for construction, then the footings can be de- signed for an allowable bearing pressure of 3 ksf and founded on prepared structural fill as described in Section 8.1, Subgrade Preparation. For static loading conditions, footings will experience settlement as loads are applied to the footings. For footings less than 5-foot-square, we estimate that total settlements from long- term loads will be less than one inch and differential settlements will be approximately half of the total settlements. Actual settlement will depend on preparation of the subgrade prior to concrete placement. 4.2 Upward Resistance Upward building forces can be resisted by the self -weight of the footing and compacted soil above the top of footing. Only soil within the vertically projected footprint of the footing Project No: 107 9 KC Interim South Base - Geotech Report (DRAFT).docx DRAFT Clarity Engineering LLC should be considered. The soil unit weight above the footing can be assumed to be 125 pounds per cubic foot if compacted, structural fill is used. 4.3 Lateral Resistance Shallow foundations can resist lateral forces by the combination of sliding resistance along the base of the footing and passive pressure against the face of the footing. An ultimate co- efficient of friction for footings and slabs founded on structural fill can be assumed to be 0.55. Ultimate passive resistance for footings can be calculated using an equivalent fluid weight of 450 pounds per cubic foot. A minimum factor of safety of 1.5 should be used for sliding. 4.4 Mat Foundations and Slabs -on -Grade Mat foundations and slabs -on -grade founded on prepared subgrade can be designed assum- ing a Winkler spring model. A coefficient of subgrade reaction for a 1-foot square plate is estimated to be approximately 150 pounds per cubic inch. This coefficient can be modified to larger slabs sizes using the equation Where, ks = kl (1+Blz \4B J ks = kl (]+B)2 zB for footings/slabs where B < 20 for footings/slabs where B >_ 40 Ks = modulus of subgrade reaction, interpolate for intermediate values of B Ki = modulus of subgrade reaction, 1-foot square plate B = Foundation width Slabs should be underlain by a minimum of 6-inches of compacted drainage layer to serve as a sub -slab drainage and capillary break layer. Slabs -on -grade constructed below the design groundwater level should be designed to resist uplift forces induced by hydrostatic pressures. The pressure will be equal to the depth of the base of the slab below the groundwater level multiplied by the density of water. • 5 SUBGRADE WALLS For retaining walls backfilled on one side only, the structural engineer can estimate the lateral load and resistance on the walls using an equivalent fluid to represent the soil. We make the Project No: 107 10 KC Interim South Base - Geotech Report (DRAFT).docx DRAFT Clarity Engineering LLC following recommendations for walls with backfill placed per the structural fill recommen- dations as follows: • Retaining wall footings should be designed as described in Section 4, Shallow Foun- dations; • For a yielding wall, defined as one in which the top rotates at least 0.1 percent of the wall height, with level backfill, the wall should be designed for an active horizontal equivalent fluid density of o 35 pounds per cubic foot (pcf) for soils above the design groundwater level, or; o 18 pounds pcf for soils below the design groundwater level. • For a non -yielding wall with level backfill, the wall should be designed for an at -rest equivalent fluid density of o 55 pcf should be used for soils above the design groundwater level, or; o 28 pcf for soils below the design groundwater level. • For seismic loads, add an incremental uniform earth pressure equal to 8H pounds per square foot (psf) where H is the height of the wall in feet to the active or at -rest earth pressures. • For uniform surface surcharges within a horizontal distance equal to the retained height of the wall, a uniform earth pressure should be applied to the wall. This uni- form earth pressure can be calculated as the uniform surface surcharge multiplied by 0.3 and 0.45 for active and at -rest wall conditions, respectively. • For passive resistance, use an ultimate passive equivalent fluid density of 550 pcf. The top two feet of soil providing passive resistance should be ignored. A factor of safety of at least 1.5 should be used in computing resistance to lateral loads. • For portions of the wall below the design groundwater level, a hydrostatic water pres- sure should be added to both the active and passive earth pressures. The water pres- sure will start at zero at the groundwater level and increase hydrostatically with depth at a rate of 62.4 pounds per cubic foot. • Hydrostatic uplift pressures will act on the base of retaining wall footings constructed below the groundwater level. The pressure will be equal to the depth of the base of the footing below the groundwater level multiplied by the density of water. Project No: 107 11 KC Interim South Base - Geotech Report (DRAFT).docx DRAFT Clarity Engineering LLC Note that these densities do not consider any surface loading conditions other than uniform surface surcharges. Clarity Engineering should be consulted to evaluate other surcharges conditions if they occur. 6 DEWATERING CONSIDERATIONS For dewatering purposes, we understand that excavations up to 5 feet below the groundwa- ter level will be required. Shallow excavations above the groundwater level may also en- counter localized seepage. Based on our understanding of the subsurface conditions, we as- sume that sumps and pumps could be used to manage groundwater inflow in these excava- tions. Additional test pits will be performed in November 2018 to further evaluate the use of sumps and pumps for excavation dewatering. 7 SURFACE WATER INFILTRATION CHARACTERISTICS Pilot Infiltration Tests (PITs) are scheduled to be performed in November 2018 to assess in- filtration at the site. For planning purposes, we estimated preliminary infiltration character- istics of the near surface soils based on grain -size tests performed on samples collected from the borehole explorations. The recommendations in this section are preliminary and will be updated for the final version of this report. Our evaluation of the subsurface infiltration characteristics is in general accordance with the Department of Ecology's 2014 Stormwater Management Manual for Western Washington (SMMWW). This manual was used to evaluate short-term infiltration rates for the soils tested. Correction factors to address uncertainties associated with variability in the subsur- face soils and the amount of siltation and bio-build-up that could occur over the design life of the facility were applied to these short-term infiltration rates to calculate a long-term de- sign infiltration rate. The SMMWW requires the base of all infiltration systems to be at least 5 feet above the seasonal high groundwater level, bedrock, or other low permeability layer. Per the SMMWW, this separation may be reduced to 3 feet if a ground water mounding anal- ysis, volumetric receptor capacity, and the design of the overflow and/or bypass structures are judged by the site professional to be adequate to prevent overtopping and meet design goals. Project No: 107 12 KC Interim South Base - Geotech Report (DRAFT).docx DRAFT 7.1 VM Building Clarity Engineering LLC For the area around the VM building including the western boundary of the site we recom- mend a preliminary design infiltration rate of 1 to 2 inches per hour. These rates include correction factors assuming the PIT tests will be performed. While these infiltration rates may occur, the groundwater levels in this area were measured to be within four feet of the ground surface and may rise in the wet weather months. These seasonal high groundwater levels may result in insufficient separation between the groundwater level and the base of the infiltration facility. 7.2 OPS Building For the area around the OPS building including the eastern boundary of the site we recom- mend a preliminary design infiltration rate of 0.5 to 1 inch per hour. These rates include correction factors assuming the PIT tests will be performed. As discussed in Section 2.3.2, groundwater levels may occur as high as 6 feet below the ground surface based on the current groundwater level and historic fluctuations measured in the 1970's at the King County South Base facility to the north. 7.3 GROUNDWATER MOUNDING Groundwater mounding is an upward and outward expansion of the free water table, which results from a surface recharge method. Mounding can alter groundwater flow; however, the effects are often localized and may be temporary, depending on the frequency and duration of the surface recharge events. The 2014 SMMWW requires a groundwater mounding anal- ysis for projects where runoff from more than one acre will be infiltrated, or where it is de- sired to reduce the vertical separation between the bottom of the facility and the groundwater level to 3 feet. A groundwater mounding analysis was not in our scope of services. Clarity Engineering should be consulted if the above criteria are met and a mounding analysis be- comes necessary. 8 EARTHWORK 8.1 Subgrade Preparation Subgrade preparation for the new facilities should begin with the removal (stripping) of all deleterious matter, asphalt, concrete, and existing structures. Given the variability of Project No: 107 13 KC Interim South Base - Geotech Report (DRAFI').docx DRAFT Clarity Engineering LLC subsurface conditions, additional subgrade preparation will vary based on the proposed structure locations. 8.1.1 VM Building Footings The subsurface conditions near the proposed VM building location indicate dense to very dense native sands within a few feet of the ground surface. Given the bearing pressures recommended for this area, the footings subgrade should be prepared such that the footings are founded on undisturbed, dense to very dense native sand. This may require localized overexcavation of fill and other soils disturbed by demolition or construction activities. The contractor should consider the use of rat slabs of concrete or controlled density fill (CDF) to preserve the bearing conditions of the native sand. The footing excavations should also be maintained in state where surface water and groundwater are not allowed to flow into the excavation and pond on the footing subgrade. Footing excavations that require overexcava- tion to expose the bearing soils may be backfilled with CDF up to the base of footing eleva- tion. In this case the CDF backfill should have a width equal to the footing width plus twice the overexcavation depth and be centered on the footing location. 8.1.2 OPS Building A stormwater detention pond is currently present at the proposed location OPS Building. We understand the detention pond's infrastructure includes concrete, rip -rap, liner, organic material, and other physical features will be demolished and removed. We anticipate the demolition will expose undocumented fill placed during the initial backfilling of the quarry site. The excavation created by the detention pond demolition should be backfilled with structural fill, as described in Section 8.2, Structural Fill, prior to the placement of slabs -on - grade and building footings. It is possible that the demolition will occur below levels where groundwater seepage could occur. The contractor should be prepared to use sumps and pumps to control groundwater inflow. 8.1.3 Slabs -on -Grade Exposed subgrade for slabs -on -grade should be observed and evaluated by Clarity Engineer- ing. For the mat foundation areas, this evaluation should be performed by proof -rolling the exposed subgrade with a fully loaded dump truck. Where truck access is restricted, the sub - grade should be evaluated by probing the soil with a steel T-probe. Soft/loose soils identified Project No: 107 14 KC Interim South Base - Geotech Report (DRAFT).docx DRAFT Clarity Engineering LLC during subgrade preparation should be compacted to a firm and unyielding condition or over -excavated and replaced with structural fill, as described in Section 8.2, Structural Fill. If the subgrade requires additional filling to meet design elevations, then structural fill should be used above the proof -rolled or T-probed subgrade. 8.2 Structural Fill Structural fill will be required in areas where the site grade must be raised to proposed slab and footing elevations. Structural fill should meet the gradation requirements of Type 17 material in Section 9-03.16, Mineral Aggregate Chart in the City of Seattle Standard Specifi- cations. We estimate that some of the on -site material may be suitable for re -use as structural fill. Some of the excavated fill and native deposits could be silty and above optimum mois- ture content, and thus may be unsuitable for re -use as structural fill unless it is moisture con- ditioned to within 3 percent of the optimum moisture content. Depending on the project schedule, area available for moisture conditioning, and the time of year when construction is planned, moisture conditioning may be very difficult or not feasible. If moisture condition- ing is required and not feasible, material that meets the criteria should be imported. Clarity Engineering should evaluate the use of on -site material or any proposed imported materials or on -site soils for suitability as structural fill. The Contractor is responsible for protecting stockpiled material from becoming unsuitable while it is on site. Structural fill should be placed in uniform lifts and compacted to at least 95 percent of the Modified Proctor maximum dry density (ASTM International [ASTM] Designation: D 1557). For structural fill placed more than two feet below proposed base of footing and slab eleva- tions should be compacted to at least 90 percent of the Modified Proctor maximum dry den- sity. The thickness of soil layers before compaction should not exceed 10 inches for heavy equipment compactors and 6 inches for hand -operated mechanical compactors. The most appropriate lift thickness should be determined in the field using the contractor's selected equipment and fill and verified with in -situ soil density testing. All compacted surfaces should be sloped to drain to prevent ponding. Structural fill operations should be observed and evaluated by Clarity Engineering. Project No: 107 15 KC Interim South Base - Geotech Report (DRAFT).docx DRAFT 8.3 Wet Weather Considerations Clarity Engineering LLC If earthwork is to be performed or fill is to be placed in wet weather or under wet conditions when control of soil moisture content is not possible, the following recommendations should apply and be incorporated into the contract specifications: • The ground surface in and surrounding the construction area should be sloped as much as practical to promote runoff of precipitation away from work areas and to prevent ponding of water. • Work areas or slopes should be covered with plastic. The use of sloping, ditching, sumps, dewatering, and other measures should be employed as necessary to permit proper completion of the work. • Earthwork should be accomplished in small sections to reduce exposure to wet con- ditions. That is, each section should be small enough so that the removal of unsuitable soils and placement and compaction of clean structural fill could be accomplished on the same day. The size of construction equipment may have to be limited to prevent soil disturbance. It may be necessary to excavate soils with a backhoe, or equivalent, located so that equipment does not pass over the excavated area. Thus, subgrade dis- turbance caused by equipment traffic would be reduced. • Fill material should consist of clean, well -graded, pit -run sand and gravel soils, of which not more than 5 percent fines by dry weight passes the No. 200 mesh sieve, based on wet sieving the fraction passing the 3/4-inch mesh sieve. The gravel content should range from between 20 and 50 percent retained on a No. 4 mesh sieve. The fines should be nonplastic. • No soil should be left uncompacted and exposed to moisture. A smooth -drum vibra- tory roller, or equivalent, should roll the surface to seal out as much water as practical. • In -place soil or fill soil that becomes wet and unstable and/or too wet to suitably com- pact should be removed and replaced with clean, granular soil (see gradation require- ments above). • Excavation and placement of structural fill material should be observed on a full-time basis by Clarity Engineering. • Grading and earthwork should not be performed during periods of heavy, continuous rainfall that prevents compaction requirements from being met. Project No: 107 16 KC Interim South Base - Geotech Report (DRAFT).docx DRAFT 8.4 Temporary Slopes Clarity Engineering LLC All shoring and excavation work (and all project work) should be accomplished in compli- ance with applicable local, state, and federal safety codes. The contractor should be made responsible for meeting these codes, the stability of all temporary cuts and slopes, and control of all surface and groundwater encountered during construction. We anticipate that excavations can be accomplished with conventional excavating equip- ment, such as a dozer or track hoe. For planning purposes, vertical cuts up to 4 feet may be attempted vertically in unsaturated soil, if there are no indications of slope instability. How- ever, vertical cuts should not be made near property boundaries, or existing utilities and structures. For cuts greater than 4 feet, we recommend that temporary unsupported, open - cut slopes should be no steeper than 1.5H:1V. Exposed cut slopes may need to be protected with a waterproof covering during periods of wet weather to reduce sloughing and erosion. Ditching sumps, trench drains, and other measures may need to be used as necessary to permit proper completion of the work. Surface water should not be allowed to flow into excavations. 9 SITE DRAINAGE CONSIDERATIONS Site grading should be planned to transmit water away from buildings and slabs. Perimeter, sub -slab, and footing drains should be used for the buildings and hydraulically connected to drain the capillary break layer. These drains should consist of 4-inch diameter perforated pipe wrapped in filter fabric and placed on a bed of and surrounded by 6 inches of clean free - draining sand and gravel. Roof drains and pavement drainage should not be tied into footing drains. 10 ADDITIONAL SERVICES The conclusions and recommendations presented in this report assume that Clarity Engineer- ing will continue to be consulted to perform the following services that are included in our current contractual scope of services: • Perform four test pits and conduct Pilot Infiltration Tests. • Collect VWP measurements of groundwater levels through the end of Spring 2019.

The locations of both the recent and applicable existing explorations are shown on Figure 2 - Site and Exploration Plan in the main text of this report. A-2 BORINGS The explorations boreholes, designated MW-1, B-2, B-3, and MW-4, were drilled by Holt Ser- vices of Edgewood, Washington, under subcontract to Clarity Engineering, from September 4 through 6, 2018. The borings were drilled using a B-52 truck -mounted rig. Borings MW-1, B-3, and MW-4 were drilled using mud -rotary drilling techniques. Boring B-2 was drilled using hollow -stem auger techniques so that groundwater during drilling could be observed. Boring depths ranged from 25.5 to 30.5 feet below the existing ground surface. Washington one -call was contacted with at least 48 hours of notice prior to commencing bor- ing activities. Given numerous underground utilities at the site, we subcontracted with APS Locate Services to surface locate potential utilities with the area of exploration. The soils encountered in the borings were classified in general accordance with the Unified Soil Classification System, as described in Figure A-1. The logs of the borings are after this figure. A-3 INSITU TESTING Standard Penetration Tests (SPTs) were generally performed in the borings at 2.5-foot inter- vals in the upper 20 feet and at 5-foot intervals thereafter. A near surface grab soil sample was collected from boring B-2. The SPT tests were performed in general accordance with ASTM International (ASTM) Designation: D1586, Standard Method for Penetration Test and Split -Barrel Sampling of Soils. The SPT consists of driving a 2-inch outside -diameter split - spoon sampler a total distance of 18 inches into the bottom of the boring with a 140-pound hammer falling 30 inches. The number of blows required to cause the last 12 inches of pene- tration is termed the Standard Penetration Resistance (N value). When penetration re- sistances exceed 50 blows for 6 inches or less of penetration, the test is terminated and the Project Nu: 107 Al•KC Interim South Base • Gaoled, Report (ORAFT).docr DRAFT Clarity Engineering LLC number of blows and the corresponding penetration are recorded. The N-values were rec- orded by a representative from our firm and are noted and plotted on the log of the boring. The N-values provide a means for evaluating the relative consistency (stiffness) of cohesive soils and the relative compactness or density of cohesionless (granular) soils. A more detailed description of the N-values and how they relate to soil characteristics is presented in Figure A-1. The split -spoon sampler used during the penetration testing recovers a disturbed sample of the soil. Recovered samples were classified in the field and recorded on the logs by our field representative, sealed in jars, and submitted for laboratory testing. Laboratory testing was later performed on selected samples; the results of the testing are presented in Appendix B: In general, after each boring was completed, the bore hole was filled with bentonite chips, and the ground surface was restored to its pre-existing elevation. Restoration consisted of either a concrete patch or a flush -mounted well monument. Groundwater pressure monitoring instruments, vibrating wire piezometers, were installed in borings MW-1 and MW-2 at depths indicated on the boring logs. The surface of these boring was completed with a flush -mounted well monument head, cemented into place. A battery -operated data logging device was attached to the instrument wires and placed in the monument casing to allow for daily groundwater pressures to be recorded. The recorded groundwater pressures were used to calculate the groundwater piezometric level at the ex- ploration location. A-4 Test Pits and Pilot Infiltration Tests The explorations and field tests are planned for November 2018 and will be included in our final document.

The samples were tested to determine basic index, physical, and chemical properties of the subsurface soils. The laboratory testing program was selected by Clarity Engineering and performed at the Shannon & Wilson, Inc. laboratory in Seattle, Washington. The results of the laboratory tests performed for the borings are shown in the attached table and figures. B-2 VISUAL CLASSIFICATION Soil samples recovered from the borings were visually reclassified in the laboratory using a system based on ASTM International (ASTM) Designation: D2487, Standard Test Method for Classification of Soil for Engineering Purposes, and ASTM Designation: D2488, Standard Recommended Practice for Description of Soils (Visual -Manual Procedure ASTM, 2007). This visual classification method allows for convenient and consistent comparison of soils from widespread geographic areas. Using this method, the soils are classified using the Unified Soil Classification System (USCS). The individual sample classifications have been incorpo- rated into the boring logs presented in Appendix A. B-3 Water Content Determination The natural water content of select soil samples recovered from the field explorations was determined in general accordance with ASTM Designation D 2216, Standard Method of La- boratory Determination of Water (Moisture) Content of Soil and Rock by Mass. Comparison of water content of a soil with its index properties can be useful in characterizing soil unit weight, consistency, compressibility, and strength. Water content, where tested, is plotted on each of the boring logs presented in Appendix A. B-4 GRAIN SIZE ANALYSES Grain size analyses were performed on selected samples of granular soils in general accord- ance with ASTM D422, Standard Method for Particle -Size Analysis of Soils and D1140, Amount of Material in Soils Finer than the No. 200 (75 micrometers jNmj; percent fines).

INTRODUCTION This report presents the results of the final foundation exploration for the proposed South Operating Base and the Unit Repair Facility to be constructed for the Municipality of. Metropolitan Seattle in King County, Washington. A preliminary soils evaluation report (Task F) was submitted December. 3, 1975. The purpose of that earlier phase was to d ter:rine the general subsurface conditions as an aid in developing a site layout plan for the'vartou.s facilities. Since that time, additional -exploration, testing, and engineering studies have been completed for the purpose of providing foundation recom- mendations for the final design of the proposed facilities. All previous exploration and laboratory test data is included herein. The site layout studied is that shown on the Site Plan, Drawing 1. Technical details for the proposed site development and building designs were taken from the "Phase I Preliminary Design Report - South Operating Base" by DeLeuw Cather & Company. The scope of work for this phase of the investigation included additional drilling of twelve subsurface borings from 11 to 29 deep, excavating of fifteen test pits 5 to 12 feet deep, classi cation and laboratory testing of the soil samples obtained, engi- neering analyses based on the laboratory and field data, and the development of recommendations based on these and other considera- tions.

All samplers were m N N M driven by mean:: of a 140-pound hammer dropping a distance of 30 inches. Normally each sample was obtained by an 18-inch penetration of the sampler and the number of hammer blows for each 6-inch incre- o ment was recorded. The blow counts shown on the boring logs are N 0 N for such 6-inch increments except as noted where lesser penetration was achieved. The blow counts required to drive the 3.25 O.D. and 3.00 O.D. samplers have been converted by estimating to standard In borings B1 through B11, the bedrock was drilled and core samples .n .n 0 0)0 0N obtained utilizing a 5' long NX core barrel. Drill fluid consisted �° of a constant flow of fresh water that was not recirculated.

Continuous logs of the subsurface conditions were made at the time of the ex- cavation. In addition, ground water conditions and stability of the excavated walls were noted.. Representative bulk soil samples were obtained at regular intervals during excavation. The soils encountered are shown graphically on the test pit logs, Drawings A-36 through A-55. Five field density tests were taken in certain of the test pits and the results are presented in Appendix B. In as many borings and test pits as possible, measurements of the stabilized ground water level were recorded. The levels, with the dates recorded, are noted on the boring logs. All borings and test pits were backfilled at the conclusion of the field exploration. Nine piezometers, consisting of a 24-inch long slotted "Hydrotip" and a h-inch diameter plastic riser pipe to the ground surface were installed with the tips packed in gravel in borings Bl, B4, B6, B7, B9, B11, B16, B19 and B22 for periodic water level obser- vations following drilling. The subsequent groundwater measure- ments recorded in the piezometers together with the date of the reading, are tabulated in the text in Section 4.4, Ground Water. Those samples, including rock cores, not completely used for testing have been stored in our laboratory and are available for examination should it be desired. Due to the elapsed time since they were secured, changes in moisture content and appearance of the samples have occurred. CONVERSE DAVIS DIXON ASSOCIATES.

Subsurface conditions at the site were explored by drilling three borings to a maximum depth of iwentyone and one-half (21.51 feet below existing grade. The borings were drilled by Aasocleted Drilling Inc. using a truck•nwunted drill rig. Contlnuous•fllgh), hollow -stem augers were used to advance and support the borsholaa during 'emoting. Approximate boring locations were determined by pacing from features as 'town on iM site map provided by the client. TM locations of the borings should be considered accurst', only to the degree implied by the method used. These approximate locations are shown on the Boring Location Pin, Pits 2. The field exploration was continuously monitored by a geologist from our firm who classified tha soils encountered, maimsined a leg of rich boring, obtained representative samples, end observed pertinent sits features. All samples were vlsuelly clmllled In accordance with the Unified Soil Classification System which is presented on Piste Al, Legend. Pepruentetive Boll samples ware placed In closed contalner' and returned to our laboratory for further examination end testing. Standard Panatretlon Tots (SPT) were performed at 'elected Interveb In general accordance with ASTM Test Designation D-15136. The split spoon sempies were driven with a one hundred forty 1140) pound hemmer freely felling thirty (301 Inches. The number of blows required to drive the last twelve (121 Inches of penetration are called the "N-value". This value helps to cheractarfes the site soils and Is wed In our engineering 'wises. Logs of the borings are presented on Pates A2 through Ai. The finer logs represent our Interpretations of the Seal logs and the results of the le9oretory exsmihetion and tests of field Samples.

I hereby acknowledge and agree that the jurisdiction does not and will not assume liability for the sufficiency, suitability, or performance of drainage facilities designed by me. Technical Information Report South Interim Base October 2018 iv 1.0 PROJECT OVERVIEW King County Metro Transit Division proposes developing a new Transit Operations Base in the City of Tukwila. This facility will expand the existing South Base facility (located at 12100 East Marginal Way South in Tukwila) with an interim base consisting of an operations building, a vehicle maintenance building, and additional bus coach parking for up to 126 buses. The South Interim Base will be located to the south of the existing facility at 12400 East Marginal Way South (Parcel No. 7340600480). The parcel is zoned as MIC/L — Manufacturing Industrial Center/Light Industrial. A parking garage and commercial office building currently occupy the project site. The parking garage will be retained; however, the existing office building will be demolished as part of an earlier phase of this project. The Transit Base will provide the following features: • Electrical upgrades, landscaping, and lighting. • Buildings for Transit operations and vehicle operations and maintenance staff. • Relocation of a drainage detention and upgraded water quality facilities. • Development of transit parking. • Separated employee parking entrance to garage. This Technical Information Report (TIR) will review the storm drainage design requirements according to the 2016 King County Surface Water Design Manual (KCSWDM) and the 2010 City of Tukwila Infrastructure Design and Construction Standards (IDCS) manual. The TIR worksheet is located in Figure 1. 1.1 PREDEVELOPED CONDITIONS For the purposes of this TIR, predeveloped conditions shall correspond to the project site's existing conditions prior to any demolition activity. 1.1.1 Parking Garage A multistory parking garage is currently located in the northwestern quadrant of the property. The parking garage is accessed via the main property entrance on East Marginal Way South, with pedestrian access connecting to the sidewalk in the Marginal Way Right -of -Way near the northwest corner of the property. The parking garage will be retained for use in the developed condition. Adjacent landscaping will be retained to the greatest extent practicable. 1.1.2 Commercial Office Building A two-story office building currently sits near the center of the site. The building has a net footprint of approximately 167,900 square feet (3.85 acres) and is slated to be demolished as part of the demolition phase of this project. Technical Information Report South Interim Base October 2018 5 1.1.3 Stormwater Infrastructure Currently, stormwater onsite drains to two distinct locations: one near the northeastern corner of the site and one to a catch basin in the Marginal Way Right -of -Way. As discussed in Section 3.0 of this report, these sub -basins are two distinct threshold discharge areas (TDAs), with TDA 1 corresponding to the portion draining to the north eastern corner and TDA 2 corresponding to the portion draining to the Marginal Way Right -of -Way. TDA maps can be found in Figure 3. TDA 1 Stormwater infrastructure in TDA 1 consists of an existing pipe and catchbasin network, a combined wetpond/detention pond (separated into two cells by a 7'-3" tall baffle located in the middle of the pond), and a flow control riser structure. The combined pond has a total depth of approximately 10 feet and provides a dead storage (for stormwater treatment) of 44,000 ft3 (1.010 ac-ft) and a live storage of approximately 25,533 ft3 (0.586 ac-ft). The storm pipe inletting to the combined pond has an invert elevation below that of the invert that outlets from the riser structure, thus creating a permanent tailwater condition in the upstream pipe network. Each catchbasin rim elevation, however, is set to be either at or above the top of the riser, so overtopping of structures upstream of the combined pond likely does not occur except in extreme storm events. TDA 2 Stormwater infrastructure in TDA 2 consists of an existing pipe and catchbasin network. The network discharges directly into a catchbasin located in the East Marginal Way Right -of -Way with no onsite detention or water quality treatment. 1.1.4 Other Utilities The property is currently served by sanitary sewer, water (potable, irrigation, and fire protection), and power. With the exception of sanitary sewer and potable water, all utilities serve both the existing commercial office building and the existing parking garage. Additionally, the fire protection water line forms a complete loop around the existing office building. 1.2 DEVELOPED CONDITIONS 1.2.1 Proposed Buildings and Site Use The project proposes to construct two new buildings: an operations building in the northeastern corner of the property and a vehicle maintenance building in the southwestern corner. The majority of the site will be paved or overlaid to accommodate bus coach parking, storage, and circulation. A new driveway entrance will be constructed to facilitate access to the existing parking garage while keeping passenger vehicle traffic separate from bus coach traffic. 1.2.2 Stormwater Infrastructure As discussed in Section 3.0 of this report, this project is divided into two distinct TDAs. Due to vertical constraints, the TDA boundaries needed to be adjusted to accommodate the proposed stormwater infrastructure (See Figure 3). Each TDA is described below: Technical Information Report South Interim Base October 2018 6 TDA 1 In the proposed condition, TDA 1 will provide detention using modular chamber technology. The facility will provide approximately 14,898 ft3 (0.342 ac-ft) of live storage at a depth of 3.67 feet. A full description of the detention facility can be found in Section 4.4 of this report. TDA 1 requires Enhanced Basic water quality treatment. The entire site is also considered "High -Use" and requires oil control. Both these requirements will be a Contech Filterra (or approved equal), which is capable of providing both Enhanced Basic treatment and Oil Control in a single facility. See Section 4.5 of this report for further information. TDA 2 In the proposed condition, TDA 2 will increase the 100-year peak flow by 0.0176 cubic feet per second (cfs). Since this increase is less than 0.1 cfs, flow control is not required for this TDA. TDA 2 also requires Enhanced Basic water quality treatment and is also classified as "High -Use." Treatment will be provided with two Contech Filterra units, which are capable of providing both oil control and Enhanced Basic treatment in a single facility. 1.2.3 Other Utilities The project proposes to retain the majority of onsite utilities. Additional sanitary sewer connections will be made to all proposed buildings in the form of side sewers. Such connections will be made to the existing, onsite sanitary sewer infrastructure. New potable water lines will be necessary for all proposed buildings. Fire prevention lines, non -potable lines, and irrigations lines will be maintained and extended as necessary. Temporary power installed during the demolition phase of this project will be retained and upgraded to be undergrounded and permanent. 1.3 SOILS AND GROUNDWATER The United States Department of Agriculture (USDA), National Resource Conservation Service (NRCS) has not mapped soils within the project vicinity. At the time of this 90% design TIR, a draft geotechnical engineering report has been prepared by Clarity Engineering, LLC (Appendix D — Other Reports and Studies). Clarity Engineering notes that the property used to be part of the Riverton Quarry, and has been subject to backfill following the quarry's closure. The content of the backfill is largely unknown, save for areas tested by other geotechnical investigations. Clarity engineering found silty sands and gravels below the backfill. An infiltration rate of 0.5-2.0 inches per hour is recommended for stormwater design, however Clarity Engineering noted the presence of high groundwater tables (within four feet of the surface) when they performed a summer inspection. Further investigation is set to be performed in November 2018 to better characterize the seasonally high groundwater table. For the time being, this TIR assumes infiltration to be infeasible to remain conservative in our design.

While the on -site grading and drainage patterns will change with this development, stormwater management and runoff detention will be provided in such a way that the runoff flowrate durations exiting the site boundaries match those of the existing condition as specified in the KCSWDM and the Tukwila IDCS. Runoff generated by the proposed development is not expected to create significant adverse impacts to downhill properties or downstream drainage facilities. 2.1.1.2 Core Requirement #2: Offsite Analysis A qualitative, Level 1 Offsite Analysis has been performed for this project at the time of this submittal. A more in-depth, quantitative analysis may be required by Tukwila on a future submittal. Please refer to Section 3.0 for the full analysis. 2.1.1.3 Core Requirement #3: Flow Control This project is divided into two distinct Threshold Discharge Areas (TDAs; see Section 3.0 for TDA delineation and justification), with TDA 1 draining to the east and TDA 2 draining to the West. TDA 2 is exempt from the Flow Control requirement (see Section 4.4 for justification), while TDA 1 will provide subgrade detention to match the Level 2 — Conservation to Existing duration requirement, as specified in the Tukwila IDCS. Specifications of the Flow Control design can be found in Section 4.4 of this report. 2.1.1.4 Core Requirement #4: Conveyance System Two distinct conveyance systems have been designed for this project; one for each TDA. Both a Uniform Flow Analysis and a Backwater Analysis were performed for each TDA to verify pipeful velocities and ponding depth due to downstream tailwater constraints. The full analysis can be found in Section 4.5.1 of this report. 2.1.1.5 Core Requirement #5: Erosion and Sediment Control A full Construction Stormwater Pollution Prevention Plan (CSWPPP) is provided as a separate attachment, along with Temporary Erosion and Sediment Control (TESC) Plans. The CSWPP recommends Best Management Practices for managing stormwater runoff during construction only. Post -construction pollutant management is specified in the Operations and Maintenance Manual. Technical Information Report South Interim Base October 2018 19 2.1.1.6 Core Requirement #6: Maintenance and Operations A full Operations and Maintenance (O&M) Manual is included as a separate attachment. The O&M manual addresses operating and maintaining onsite stormwater infrastructure and facilities. The O&M manual also includes pollutant source control management for the post -construction site. For pollutant management BMPs that should be used during construction, refer to the CSWPPP. 2.1.1.7 Core Requirement #7: Financial Guarantees and Liability Any required financial liability documents will be prepared for the project during the final engineering permitting process with the City of Tukwila. 2.1.1.8 Core Requirement #8: Water Quality This project is required to meet Enhanced Basic stormwater quality treatment standards. Enhanced Basic Treatment is intended to remove dissolved metals in addition to the removal of total suspended solids that Basic treatment provided. The full design of the water quality system can be found in Section 4.5 of this report, however a summary is provided below: Treatment for both threshold discharge areas will be provided via four (4) Contech Filterra facilities. See Section 4.5 of this report for further information. 2.1.1.9 Core Requirement #9: Flow Control BMPs The property encompasses more than 22,000 square feet and is located inside the Urban Growth Area, and it is not feasible for this project to comply with the LID Performance Standard. Therefore, the project must comply with the Large Lot BMP Requirements. The large lot BMPs are specified in an order of preference, so this project will address each requirement in the order it is specified. 1. "The feasibility and applicability of full dispersion...must be evaluated for all target impervious surfaces." INFEASIBLE: It is not possible to provide the requisite vegetated flowpath length. 2. "When full dispersion of target impervious roof areas is not feasible or applicable...the feasibility and applicability of full infiltration of roof runoff must be evaluated..." INFEASIBLE: Seasonally high groundwater tables are estimated to occur as high as one foot below the ground surface. It will not be possible to maintain a three-foot separation between the bottom of an infiltration facility and the seasonally high groundwater table. 3. "All target surfaces not mitigated by Requirements 1 and 2 above, must be mitigated to the maximum extent feasible using one or more BMPs from the following list." a. Full Infiltration INFEASIBLE: Seasonally high groundwater tables are estimated to occur between one and five feet below the ground surface. It will not be possible to maintain a three-foot separation between the bottom of an infiltration facility and the seasonally high groundwater table. b. Limited Infiltration Technical Information Report South Interim Base October 2018 20 c. INFEASIBLE: Seasonally high groundwater tables are estimated to occur as high as one foot below the ground surface. It will not be possible to maintain a three-foot separation between the bottom of an infiltration facility and the seasonally high groundwater table. Bioretention FEASIBLE: Preliminary geotechnical studies show that it may be possible to provide one -foot of vertical separation between the seasonally high groundwater and the bottom of a shallow, open -to -air facility. A preliminary design infiltration of 0.5-2 inches per hour was calculated. However, the project geotechnical engineer will make a future site investigation in late 2018 or early 2019 to improve their estimation of the seasonally high groundwater table. The only target surface for Core Requirement #9 is new impervious surfaces (i.e. impervious surfaces that replace pervious surfaces), however we will apply the bio- retention BMP to a majority replaced impervious surface since the site is already approximately 86% impervious. The site is within the Urban Growth Area, so assuming till soils onsite the equivalent storage depth for impervious surfaces is 0.6 inches. Approximately 40,000 ft2 of impervious surfaces will drain directly to the bioretention swale: V = (Tributary Area) (Equivalent Storage Depth) V = (40,000 ft2)(0.6 in) (1 ft) = 2,000 ft3 12 in The minimum required storage volume is 2,000 cubic feet. However, the swale volume provided is approximately 3,180 cubic feet, thus providing additional potential for infiltration. The design ponding depth is six (6) inches, with an additional six (6) inches of depth for freeboard. Assuming the lowest preliminary design infiltration rate, 0.5 inches per hour, the design drawdown time is 12 hours and the swale-full drawdown time is 24 hours (see the equation below); both drawdown times are 24 hours or less. Ponding Depth tdrawdown, design depth = Infiltration Rate Total Depth _ tdrawdown, total depth = Infiltration Rate d. Permeable Pavement (0.5 ft 0.6(1 ft2 'n) = 12 hr in/hr) (o.5 in/hr) (1 ft n) = 24 hr INFEASIBILE: The site use under the developed condition is a transit base and is classified as "high use." Per infeasibility criteria #27 (Appendix C, Section C.2.1.7), permeable pavement may not be used at sites defined as "high use." 4. "All target surfaces not mitigated by Requirements 1, 2, and 3 above must be mitigated to the maximum extent feasible using the Basic Dispersion BMP..." SATISFIED: All target surfaces mitigated via bioretention. Technical Information Report South Interim Base October 2018 21 5. "BMPs must be implemented, at minimum... to an impervious area equal to at least 10% of the site/lot..." SATISFIED: More than 10% of the total site area is mitigated via bioretention. 6. "The soil moisture holding capacity of new pervious surfaces must be protected in accordance with KCC 16.82.100 (F) and (G). KCC 16.82.100 (F) requires that the duff layer or native topsoil be retained to the maximum extent practicable. KCC 16.82.100 (G) requires soil amendment to mitigate for lost moisture holding capacity where compaction or removal of some or all of the duff layer or underlying topsoil has occurred...The specifications for compost amendment can be found in Reference 11-C." SATISFIED: All new pervious surfaces will be protected, and compost amended per the specifications located in Reference 11-C of the 2016 KCSWDM. 7. "Any proposed connection of the roof downspouts to the drainage system must be via a perforated pipe connection as detailed in Appendix C, section C.2.11." SATISFIED: All roof downspouts will be connected to the drainage system via perforated pipe connections, as specified in Appendix C, Section C.2.11. Technical Information Report South Interim Base October 2018 22 2.1.2 Special Requirements 2.1.2.1 Special Requirement #1: Other Adopted Area -Specific Requirements Table 1: Other Adopted Area -Specific Requirements Resource Response Critical Drainage Areas (CDAs) Master Drainage Plans (MDPs) This project ultimately drains to Riverton creek and the Duwamish River. Per the Washington State Department of Ecology's Impaired Waterbody List 303(d)/303(b) and the City of Tukwila's 2013 Surface Water Comprehensive Plan, the ,Duwamish River is impaired for Fecal Coliform, Dissolved Oxygen, Temperature, and High pH. These problems and the mitigation thereof are described in Section 3.2.4.4 of this TIR. ;This project is not subject to a Large Project Drainage Review, therefor it does not need to prepare a Master Drainage Plan. :To the best of our knowledge, this project site is not any City - or County -adopted Master Drainage Plan. Basin Plans (BPs) To the best of our knowledge, this project site is not subject to a City- or County -adopted basin plan. Salmon Conservation Plans (SCPs) This project drains to the Duwamish River, a Salmonid bearing water body. A WRIA Salmon Habitat Plan was ratified by the City of Tukwila in 2005, however to our knowledge this plan does not contain any stormwater management requirements. Stormwater Compliance Plans (SWCPs) To the best of our knowledge, the project site is not subject to any Stormwater Compliance Plans. Lake Management Plans (LMPs) This project does not drain to a lake, nor is it near or adjacent to a lake. Therefore, it is not subject to any Lake Management Plans. Flood Hazard Management Plans (FHMPs) This project does not rely on, nor does it propose, any facilities, maintenance practices, or programs covered in the King County Flood Hazard Management Program. Due to the stabilized state of the Duwamish River near the project site, the site lies outside of the 100-year floodplain. Flooding is not 'expected except in the case of catastrophic infrastructure t failures. Shared Facility Drainage Plans (SFDPs) . This project does not drain to any shared facilities, nor does it ipropose any shared facilities. 2.1.2.2 Special Requirement #2: Flood Hazard Delineation This project is located outside of 100-year floodplain (King County iMap) and is located in FEMA Flood Zone X (unshaded) — which corresponds to areas outside of both the 100- and 500-year floodplains. Technical Information Report South Interim Base October 2018 23 2.1.2.3 Special Requirement #3: Flood Protection Facilities This project does not rely on any flood protection facilities located near or directly adjacent to the property. There are currently no flood protection facilities on the property, and no flood protection facilities are proposed for this project. 2.1.2.4 Special Requirement #4: Source Control This project is a commercial development and will incorporate the appropriate pollutant source control BMPs from the King County Stormwater Pollution Prevention Manual. The Source Control Plan can be found in the Operations and Maintenance Manual, which is included as a separate attachment. 2.1.2.5 Special Requirement #5: Oil Control This project is classified as "high use," and will provide oil control per the High -Use Menu in Chapter 6 of the KCSWDM. Oil Control will be managed by a Coalescing Plate Separator in both threshold discharge areas. Please see Section 4.5 of this report for the Oil Control design and specifications. 2.2 CITY OF TUKWILA 2010 INFRASTRUCTURE DESIGN AND CONSTRUCTION STANDARDS The City of Tukwila modifies the 2009 King County Surface Water Design Manual (KCSWDM) in the 2010 Infrastructure Design and Construction Standards (IDCS). King County updated the KCSWDM in 2016, however and update to the IDCS is still in progress. For the purposes of this TIR, the specifications in the 2010 IDCS are assumed to apply to the 2016 KCSWDM and shall supersede the KCSWDM where applicable. Technical Information Report South Interim Base October 20I8 24 3.0 OFFSITE ANALYSIS 3.1 LEVEL OF ANALYSIS This project proposes to closely match the developed outflows to existing flow durations. As such, a Level 1 Offsite Analysis has been completed. If the City deems that a more quantitative analysis is necessary to accurately describe the downstream characteristics of this project, a higher -level analysis (as described in the KCSWDM) will be provided in a future submittal. 3.2 OFFSITE ANALYSIS 3.2.1 Task 1 — Define the Study Area The study area is the immediate, existing, manmade, downstream conveyance network (including pipes, ditches, culverts, etc.) that a) either define or are defined by the downstream flow path, and b) are within '/< mile (1,320 feet) of the project site. The study area also includes those areas upstream of the site that discharge directly onto the project property. For this project, such upstream areas are limited to a large hill located along the southern property line. 3.2.1.1 Define the Threshold Discharge Areas This site contains two separate Threshold Discharge Areas (TDAs). TDA 1 consists of the northeasterly portion of the site that drains into the existing combined treatment/detention pond before discharging from the site. This TDA ultimately discharges to Riverton Creek, then to the Duwamish River, but does not do so within 'A mile of the site. TDA 2 consists of the portion of the site that drains westerly towards the Marginal Way Right -of - Way. Stormwater is either captured onsite and conveyed to the storm network in Marginal Way, or sheet flows into the Right -of -Way, where it is captured by the city -maintained storm system. This runoff is then conveyed to Riverton Creek. Riverton Creek is a tributary to the Duwamish River, but it does not discharge to the larger waterbody within % mile of the project site. While the two TDA flowpaths do eventually converge in Riverton Creek, they do not converge within '/< mile of the project site. Therefore, each TDA is considered distinct by the definition specified in Chapter 1 of the KCSWDM (pg. 1-10). Technical Information Report South Interim Base October 2018 25 3.2.2 Task 2 — Review All Available Information for the Study Area The available information has been reviewed and is summarized in the table below: Table 2: Offsite Analysis Resource Review Resource Res•onse Adopted Basin Plans To our knowledge, there are no adopted basin plans for stormwater management for the Duwamish Estuary sub - watershed of the Duwamish-Green Watershed. Floodplain/Floodway (FEMA) Maps Other Offsite Analysis Reports This project is mapped as FEMA Flood Zone X (unshaded), which corresponds to areas located outside the 500-year floodplain. To our knowledge, there are no other, publicly available offsite analysis reports. Per King County iMap: • Per the 2005 CAO, the site is located in a lower tributary area. Sensitive Areas Folio • Per the 2005 CAO, the site has a "low" basin condition. • Per the 1990 SAO, the Duwamish River is classified as a Class 1 Stream and contains Chinook Salmon. Per Tukwila iMap: • Riverton Creek is classified as a Type 2 Stream (in Pipe) • The project site is directly adjacent to the Highway 599 Right -of -Way, which is subject to Shoreline Jurisdiction — Shoreline Residential/Shoreline Residential Outside Buffer. • The hill adjacent to the south property line is classified as a Class 3 (moderate) Landslide Hazard. DNRP Drainage Complaints and Studies To our knowledge, there have been no drainage complaints made or studies conducted on or adjacent to the project site. Road Drainage Problems To our knowledge, there are no road drainage problems on or adjacent to the eject site. King County Soils Survey No USDA data is available at the property location. Wetlands Inventory Maps There are no wetlands on or adjacent to the project site. Migrating River Studies Per both King County and Tukwila iMaps, the project site is not within a channel migration hazard area.

Tukwila 2013 Surface Water Comprehensive Plan Table B-2: Fecal Coliform contamination is listed as Category 5 (Table B- 2). Fecal Coliform qualifies as a Bacteria (Type 1) problem in the KCSWDM. Appendix D: "Water quality in Riverton Creek is thought to be consistent with other urbanized creeks in the Puget Sound Area showing elevated levels of fecal coliform, elevated temperatures, and low dissolved oxygen levels. Temperature, dissolved oxygen, pH, and fecal coliform are the constituents of concern in Riverton Creek based on the Category 5 (impaired) listings of the Duwamish River and the Green River. In addition to these parameters, total suspended solids and turbidity are also of concern." King County Surface Water Design Manual — Reference 11-C No water quality problems identified at this time King County Designated Water Quality Problems (Surface Water Design Manual — Reference 10, iMap) No water quality problems identified at this time. Adopted Stormwater Compliance Plans To the best of our knowledge, this project site is not subject to any adopted stormwater compliance plans. 3.2.3 Task 3 — Field Inspect the study Area A field inspection was performed on August 13th, 2018. 3.2.4 Task 4 — Describe the Drainage System, and Its Existing and Predicted Drainage and Water Quality Problems 3.2.4.1 Upstream Drainage System Analysis The property slopes generally from south to north. Due to the presence of an existing hill on the southern property boundary, very little run-on enters the site. The property line does not coincide exactly with the crest of the hill; however, the hill is heavily vegetated, stabilized, and considered to be well -drained. Although the USDA has not performed a soils survey in the vicinity of the project site (soils are assumed to be hydrologic group C), run-on is expected to be negligible. 3.2.4.2 Downstream Drainage System Analysis The two separate threshold discharge areas are discussed below: Technical Information Report South Interim Base October 2018 27 TDA 1 Runoff discharges from the site as either sheet flow or in -pipe flow and is conveyed directly into an existing ditch that extends the length of the eastern property line. Runoff then flows north in the ditch to the % mile mark. Beyond the % mile mark, the runoff will flow through a series of ditches, culverts, and minor conveyance systems until it discharges into Riverton Creek, just upstream of the confluence between Riverton Creek and the Duwamish River. TDA 2 Stormwater runoff is captured and detained on site. Detained runoff is released at controlled rates into the existing storm network in the Marginal Way Right -of -Way. Stormwater that is uncapturable sheet flows into the Marginal Way Right -of -Way, where it enters the existing storm network through catchbasin inlets. Once the runoff enters the existing storm network, it is conveyed to the west side of Marginal Way and discharges into Riverton Creek, which is conveyed under Marginal Way in a 48-inch diameter pipe. Runoff flows north in Riverton Creek to the'/< mile mark. Beyond the % mile mark, Riverton Creek discharges directly to the Duwamish River.

However, the project does drain to the Duwamish River, which, at least for the river reach to which the project drains, is listed on the Washington State Department of Ecology's Polluted Waterbodies 303(d)/303(b) List for dissolved oxygen (DO), temperature, and high pH Problems. The dissolved oxygen problem is listed as Category 2: Waters of concern. Category 2 problems have some evidence of a water quality problem, but not enough evidence to show consistent impairment. The bacteria, temperature, and high pH problems are listed as Category 5: Polluted waters that require a water improvement project. Category 5 problems have data showing violations of water quality standards, yet no pollution control program is in place. 3.2.4.4 Predicted Drainage and Water Quality Impacts The proposed developments are not anticipated to create new drainage problems, nor are the developments anticipated to exacerbate any existing drainage problems. Per Section 5.6.4.b of the IDCS: Currently, the City is not requiring mitigation target to address a specific downstream water quality problem (i.e., listing as a 303d water quality problem), but mitigation requirements may be added in future modifications to these standards. The 2010 IDCS and the 2016 KCSWDM are the most recent stormwater management standards applicable to this project, therefore this project will not provide additional water quality treatment to mitigate for downstream impaired water bodies. Technical Information Report South Interim Base October 2018 30 4.0 FLOW CONTROL, LOW IMPACT DEVELOPMENT (LID), AND WATER QUALITY ANALYSIS AND DESIGN 4.1 PREDEVELOPED SITE HYDROLOGY (PART A) As discussed in Section 1.1 of this report, the'predeveloped conditions for this project correspond to the existing site conditions prior to any demolition activity. Under the existing conditions, the project site impervious surface coverage is approximately 86%. The existing commercial office building contributes the majority of this area, with parking and associated drive aisles, sidewalks, and an existing combined treatment/detention pond accounting for the rest of the impervious area. The site is broken down by surface type in the table below: Table 3: Pre -Developed Site Breakdown by Threshold Discharge Area Type TDA 1 TDA 2 Total Area Drains to Existin • Ditch Drains to Right -of -Way Lawn and Landscaped Areas Includes all pervious surfaces except forested areas 26,594 23,595 50,189 Road Includes all pollution -generating, impervious surfaces (i.e. roads, parking stalls, gravel driveways, etc.) Roof Includes only non -pollution generating roof space. Pollution -generating roof space is considered "road". 87,827 132,632 28,548 35,473 116,375 168,105 Sidewalk Includes all non -drivable, non -roof, impervious surfaces (i.e. pedestrian access, sidewalks, hiking trails, etc.) Pond Open -to -air water surfaces are considered "impervious" under standard runoff calculation methods. 14,037 4,478 15,136 1 0 18,515 15,136 Project Totals 276,226 92,095 368,321 Note: All areas have units of square feet; all areas are considered to be "flat" unless otherwise noted. With the exception of a steep slope area (a large hill) to the south, the project site is very flat, exhibiting a total vertical relief of approximately nine (9) feet over a length of about 950 feet. The hill, spanning the length of the south property line, was neglected from hydrologic and hydraulic analysis as the hill is heavily vegetated and stabilized and no land disturbing activity is proposed in that area. Similarly, the existing parking garage is also excluded from analysis as the parking garage will be retained into the developed condition. Technical Information Report South Interim Base October 20I8 3I An existing, combined treatment/detention pond controls the outflow characteristics of TDA 1. While as - built documents have not been located for review, the civil engineering construction plans (prepared by Barghausen Consulting Engineers, Inc.) indicate that the pond is approximately 10 feet deep and provides 44,000 ft3 of dead storage (for water quality treatment) and 25,533 ft3 of live storage (for detention and release rate control). The pond riser uses a single orifice and notch weir design. The weir is six inches wide, nine inches tall, and the bottom of the notch is set to be 1.75 feet above the outletting pipe invert. The riser itself extends 2.5 feet above the outletting pipe invert and has a diameter of 12 inches. The bottom orifice is located on the bottom of the riser structure and has a diameter of 5 1/4 inches. These characteristics combined yield the following hydrologic characteristics for the predeveloped condition (as modeled by WWHM).

The majority of the site will be paved to allow for bus coach circulation and storage. Two new buildings will be constructed to facilitate operations management and vehicle maintenance. All stormwater infrastructure will be subsurface to better facilitate the intended site use. Due to vertical constraints, it was not possible to provide the required treatment train and detention facility in TDA 1 while maintaining the predeveloped condition TDA boundaries. The proposed site will be graded such that the 100-year peak flow generated by TDA 2 will not increase by more than 0.10 cfs when compared to the predeveloped 100-year peak flow; therefore TDA 2 is exempt from the flow control requirement (per Section 5.6.A.3.a of the IDCS). The detention requirement remains entirely within TDA 1, as is consistent with the existing condition. The site is broken down by surface type in the table below. Note that while the individual TDA values have changed, the total site area remains consistent with that of the predeveloped condition.

Technical Information Report South Interim Base October 2018 33 4.3 PERFORMANCE STANDARDS (PART C) 4.3.1 Flow Control The IDCS manual significantly modifies Core Requirement #3: Flow Control. Much of the City of Tukwila have been developed for several decades and their receiving waterbodies have stabilized to the new hydrologic regime. The City applies the 40/20 criterion (as specified in the Stormwater Management Manual for Western Washington, Washington State Department of Ecology) to areas that have had at least 40% total impervious surface area for more than 20 years. The subject property for this project falls under this category, however special considerations must be given to each threshold discharge area. 4.3.1.1 Application of Flow Control Standards Per Figure 5.9.1 of the IDCS, the project site is subject to Level 2 — Conservation to Existing flow control. 4.3.1.2 Flow Control Standard Requirements Level 2 Conservation to Existing flow control is analogous to Conservation Flow Control as specified in the KCSWDM, which requires that flow durations in the developed condition be match to the pre - developed condition from one half of the two-year flow to the 50-year flow and that the two- and 10-year developed peak flows not exceed their corresponding pre -developed values. The key difference between the two flow control standards is that Conservation Flow Control requires the pre -developed condition to be as historic (or forested) conditions, while Level 2 Conservation to Existing requires the pre -developed condition to be modeled as existing conditions. 4.3.2 Water Quality The IDCS notes that the water quality treatment requirement is based on land use. Given the intended use for the developed site, this project is required to provide Enhanced Basic treatment. Each TDA will select a treatment option from the Enhanced Basic Menu in Chapter 6, Section 6.1.2 of the KCSWDM. This site is also classified as "high use," so each TDA will select oil control options from the High -Use Menu located in Chapter 6, Section 6.1.5 of the KCSWDM. 4.3.3 Target Surfaces Per Core Requirements 3, 8, and 9 of the KCSWDM, the target surfaces for this project are: • New impervious surfaces that are not fully dispersed • New pervious surfaces that are not fully dispersed • Replaced impervious surfaces. Note that these target surfaces do not include any existing impervious surfaces. All existing impervious surfaces are exempt per Section 5.6.A.1 of the IDCS. Technical Information Report South Interim Base October 2018 34 4.4 FLOW CONTROL SYSTEM (PART D) Flow control has been designed for each TDA and complies with the standards set forth in Section 4.3 of this report. However, in TDA 2 the increase the 100-year peak flow (predeveloped to developed) is 0.0176 cfs, as modeled by WWHM. According to Section 5.6.A.3.a: The exception to requiring flow control in this area shall be as follows: The facility requirement in the Level 2 Conservation to Existing Conditions is waived for any threshold discharge area in which there is no more than a 0.1-cfs difference in the sum of developed 100-year peak flows for those target surfaces subject to this requirement and the sum of existing site conditions 100- year peak flows for the same surfaces. TDA 2 will increase the 100-year peak flow rate by less than 0.1 cfs, therefore it is exempt from the flow control requirement. 4.4.1 Flow Control Methodology and Computer Modeling Flow control design was performed in accordance with the KCSWDM. Continuous hydrologic modeling was performed using the Western Washington Hydrology Model (v.4.2.15, also known as WWHM2012 with the July 2018 update), which is developed by the state Department of Ecology and is listed as an approved model in the KCSWDM. The duration criteria located in the options menu of the model were modified to allow a pass/fail threshold of 100% instead of the default 110%. Under default settings, the occurrence frequency of runoff flows exceeding the 2-year discharge rate may exceed the corresponding predeveloped flow frequencies by up to 10%. This design standard is insufficient to meet Level 2 flow control as the 2- and 10-year peak flows are required to match, not exceed, predeveloped conditions. By adjusting the duration criteria settings, we ensure that any automatic detention sizing will always meet Level 2 flow control requirements. WWHM groundwater modeling functionality is limited and is generally not performed within the program unless wetlands mitigation and recharge analysis is required. There are no wetlands on, downstream from, or adjacent to the project site, so groundwater is not modeled for this project. 4.4.2 Size and location of Proposed Flow Control Facilities The proposed, subsurface detention facility for TDA 1 will be located near the eastern property line. Due to the large footprint required for detention, a standard detention vault would conflict with multiple utilities. As such, modular chamber detention technologies will be used, as they allow for utility conflicts to be easily resolved by connecting smaller detention sub -facilities with small pipes that can facilitate utility crossings. This design requires a facility with a foot print of 5,625 ft2 and a depth of 3.67 feet. Excluding freeboard, the active storage provided is 14,898 ft3 (0.342 ac-ft), and a total vault volume of 20,865 ft3 (0.479 ac-ft). The requisite riser structure is a 3-orifice design and is detailed below: Technical Information Report South Interim Base October 2018 35 Table 7: Control Structure Characteristics Feature Value Units Riser Height I 2.5 feet Riser Diameter 18 inches Orifice 1 Height 0.00 feet Orifice 1 Diameter 5 - 3/8 inches Notch Height 1.10 feet Notch Width 0.50 feet Table 8: Developed, Mitigated Site Hydrology Return Period TDA 1 TDA 1 Drains to Change from Ri • ht-of-Wa Pre -Developed 2 Year 0.9434 -0.1346 5 Year 1.2775 -0.2206 10 Year 1.5320 -0.2928 25 Year 1.8940 -0.4031 50 Year 2.1945 -0.5009 100 Year 2.5231 -0.6131 Model outputs detailing the Stream Duration are available in Appendix B - Western Washington Hydrology Model. 4.5 WATER QUALITY SYSTEM (PART E) 4.5.1 Water Quality Treatment TDA 1 TDA 1 is designed to use two Contech Filterra facilities. To meet enhanced basic treatment standards, the Filterra units are sized in WWHM per Ecology's GULD approval to provide 91% filtration. Each unit requires custom manufacturing to accommodate the large inflows generated by the site and horizontal and vertical facility footprint constraints, so functionally equivalent technologies will only be accepted if they are (1) shown to fit into the same or smaller area as the Filterra units and (2) stamped and signed by a Professional Engineer licensed in the State of Washington. TDA 1 is further divided into two sub -basins that will convey through a northern and a southern system before entering the detention facility. The northern system requires a Filterra media bay measuring 25 feet long by 18 feet wide with a total vault depth of 5 feet (rim to outletting invert). This configuration is large and deeper than standard Filterra units; at the time of this report coordination with Contech is underway to accommodate the larger facilities. Technical Information Report South Interim Base October 2018 36 The southern facility is identical to the northern one, excepting that the media bay will be 13 feet wide and 20 feet long, and the depth will also be 5 feet. TDA 2 Similar to TDA 1, TDA 2 is also split into a northern and southern sub -basin. Each drains to a Large Filterra unit located in a landscaping area adjacent to the project frontage. The northern Filterra requires a standard FTPD 0811 facility with a media bay measuring 8 feet by 11 feet. The southern Filterra requires a standard FTPD 0813 facility with a media bay measuring 8 feet by 13 feet. 4.5.2 Oil Control The Contech Filterra is sufficient to provide oil treatment by virtue of providing enhanced treatment. The GULD-approved design filtration rate for enhanced basic treatment is slower than that of the GULD- approved oil treatment filtration rate, so oil -laden inflow will be treated for oil by the same process that provided enhanced basic treatment. Since the facilities will be providing both oil control and enhanced treatment, it is expected that the media will need more frequent maintenance than it otherwise would for a single treatment goal. This increased frequency is specified by Contech and is included in the Operations and Maintenance Manual. Technical Information Report South Interim Base October 2018 37 5.0 CONVEYANCE SYSTEM ANALYSIS AND DESIGN Two distinct conveyance systems have been designed for this project; one for each TDA. Both TDAs are constrained vertically by existing infrastructure, thereby forcing several pipes in the storm network to the 0.2% minimum slope so that the network can meet the existing discharge elevations. Each TDA is described below, and all calculations referenced can be found in Appendix C — Engineering Calculations. TDA 1 Both a Uniform Flow Analysis and Backwater Analysis were performed per Section 4.2.1.2 of the KCSWDM. The Uniform Flow Analysis was performed to ensure compliance with the minimum self-cleaning velocity threshold. Section 4.2.1.1 limits the minimum velocity at full flow to 3.0 feet per second (fps) and the minimum bed slope to 0.20%. Under pipe -full conditions with HDPE pipe, and a slope of 0.20%, a 15-inch pipe is sufficient to convey the 25-year design flow of 4.07 cfs (Qcapacity = 4.17 cfs), and to provide a barrel velocity of 3.0 fps (V15 nch = 3.40 fps). The backwater analysis analyzed the pipe network along the longest trunkline from the discharge location to the upstream -most catchbasin. TDA 1 discharges to an existing ditch where the ordinary high water, 25-, and 100-year water surface elevations are unknown. As such, the tailwater elevation was assumed to be the elevation at 50% of the outletting pipes diameter in the 25-year storm event (TW = IEout + 0.5D), and 90% of the outletting pipe's diameter in the 100-year event (TW = IEout + 0.9D). Per Section 1.2.4.1 of the KCSWDM, overtopping is permitted in new pipe networks for runoff events that exceed the 25-year design capacity as long as the over flow from the 100-year event does not create or aggravate a severe flooding or erosion problem. Since there are no known downstream flooding or erosion problems, we do not anticipate 100-year event overtopping to create or exacerbate such problems. The effects of detention and water quality facilities were neglected for this analysis. Additionally, energy losses due to bends and junctions were neglected and each pipe was sized to carry the full 100-year flow. These effects will be modeled at the time of the 90% submittal. The backwater analysis shows that no overtopping will occur in either the 25- or 100-year events. TDA 2 Similarly, to TDA 1, both a Uniform Flow Analysis and Backwater Analysis were performed per Section 4.2.1.2 of the KCSWDM. The Uniform Flow Analysis was performed to ensure compliance with the minimum self-cleaning velocity threshold. Section 4.2.1.1 limits the minimum velocity at full flow to 3.0 feet per second (fps) and the minimum bed slope to 0.20%. Under pipe -full conditions with HDPE pipe, and a slope of 0.21%, a 12-inch pipe is sufficient to convey the 25-year design flow of 1.12 cfs (Qcapacity = 2.36 cfs), and to provide a barrel velocity of 3.0 fps (V15-inch = 3.00 fps). The backwater analysis analyzed the pipe network along the longest trunkline from the discharge location to the upstream -most catchbasin. TDA 2 discharges to an existing catchbasin. Since the inflow characteristics of to this catch basin are not known, the outletting pipe was assumed to be flowing at a depth of 50% of the outletting pipes diameter in the 25-year storm event (TW = IEout + 0.5D), and 90% of the outletting pipe's diameter in the 100-year event (TW = IEout + 0.9D). Technical Information Report South Interim Base October 2018 38 Per Section 1.2.4.1 of the KCSWDM, overtopping is permitted in new pipe networks for runoff events that exceed the 25-year design capacity as long as the over flow from the 100-year event does not create or aggravate a severe flooding or erosion problem. Since there are no known downstream flooding or erosion problems, we do not anticipate 100-year event overtopping to create or exacerbate such problems. The effects of detention and water quality facilities were neglected for this analysis. Additionally, energy losses due to bends and junctions were neglected and each pipe was sized to carry the full 100-year flow. The backwater analysis shows that no overtopping will occur in either the 25- or 100-year events.

Clearing Limits: Stake or fence clearing limits and identify sensitive areas and associated buffers. • Provide Cover Measures: Provide temporary and/or permanent cover measures within the timeframe prescribed by the KCSWDM for "wet season" and "dry season" to minimize erosion. Cut and fill slopes, which are susceptible to erosion and do not require additional construction. Areas should be mulched and vegetated as soon as they are graded. • Perimeter Protection: Provide filter fabric (silt fence) fencing or vegetated buffer strips down slope of all disturbed areas flowing to adjacent properties or storm drainage systems. • Traffic Area Stabilization: Provide stabilized construction entrances and construction traffic areas to prevent erosion and reduce transport of sediment onto City streets. • Sediment Retention: Route sediment laden runoff from exposed areas to temporary sediment traps prior to discharge to downstream systems. Provide catch basin inserts to filter runoff from construction areas. • Surface Water Control: Runoff draining toward disturbed areas should be intercepted and re- routed to bypass disturbed areas. Runoff from exposed onsite (roadway) areas should be collected along the project length and conveyed to the temporary sediment pond facilities prior to discharge. • Protection of Existing Storm Drainage Facilities: Existing storm drainage facilities and conveyance systems are to be protected throughout the project duration. Flows which are tributary to existing systems should be routed through sediment trapping facilities prior to entering existing system. Existing catch basins and inlets shall be protected with filters prior to earthwork operations. • Site Monitoring and Facility Maintenance Programs: All TESC facilities are to be monitored and maintained throughout the project duration. • Dust Control: Dust control measures such as sprinkling are to be incorporated to reduce impacts to adjacent properties. Technical Information Report South Interim Base October 2018 51 The primary sediment removal mechanism will be through the use of perimeter protection or filter fencing along the downstream slopes and diverting runoff away from exposed areas. Additionally, separating offsite runoff from onsite (sediment laden) runoff will reduce the required sediment trapping facility size.

RENTON Shoreline Overlay (Approelmarely 20T each side albriver) I. FINDINGS Background This application is part of the 2018-2019 annual docket for amendment of the Comprehensive Plan (the "Plan"). The purpose of an annual docket is to ensure that changes to the City's Plan are only considered once a year and that they are considered collectively for impact to the Plan. The Applicant, King County Metro, seeks to rezone the western half of a 71,440 square foot split - zoned lot located at 12677 East Marginal Way 5, Tukwila, WA 98168 (the "Property") from Low Density Residential (LDR) to Commercial Light Industrial (CLI), with corresponding Comprehensive Plan and zoning map amendments. The Property was developed in 1975 with a warehouse and offices. The Applicant is seeking the Comprehensive Plan amendment and rezone for the following reasons: 1. The parcel is split -zoned: the eastern portion fronting on E Marginal Way S is zoned Commercial/Light Industrial (C/LI) and the western portion is zoned Low Density Residential (LDR). The Property is ideal for Metro's intended future use, but the split -zoned condition creates uncertainty about how the Site could be developed to meet Metro's needs. 2. The current use of the Property since at least 1975 has been Tight industrial, specifically a truck terminal use with accessory warehouse and parking. Truck terminal use is nonconforming to the existing LDR zoning, but conforming to the C/LI zoning. Rezoning would remove confusion around applicability of zoning to the Property and its nonconforming status, encouraging future redevelopment conforming to existing regulations. 3. Rezoning the Property will strengthen the boundary between the LDR zone to the west and C/LI zone along E Marginal Way 5. This non -project proposal is a quasi-judicial change to the land use designation on the Tukwila Comprehensive Plan and Zoning Code maps. If the rezone is approved, any C/LI use would be permitted subject to all City regulations. The Applicant has stated the intention to construct new small- scale office buildings and an associated bus maintenance training bay. A neighborhood scale Comprehensive Plan and Zoning Map depicting the Property is below. The map shows existing Comprehensive Plan and Zoning designations with the Property outlined in turquoise. Existing LDR zoning is yellow, and existing CLI zoning is Tight purple. 2 jf : r - LDR CLI LDR LDR NCC M1C;L I_D R LDR Figure 1 - Comprehensive Plan and Zoning Map Site Information The Property is developed with an office building and associated warehouse structure which has been used as a trucking facility since at least 1975. The Property measures about 200' feet wide by 350' feet long on average, and extends north to south, fronting on E Marginal Way S and S 128th St. 3 The east fork of Riverton Creek flows across the northwest corner of the Property through an underground pipe. The Property contains environmentally sensitive areas, including a Type 2 watercourse (Riverton Creek) and its 100-foot buffer as shown in green on the map below." Figure 2 — Relief map with Wetlands and Watercourses Annexation and Zoning History: The subject property was created in unincorporated King County as Riverton, a replat of a portion of Riverside Interurban Tracts, on June 15, 1906. Lots 4 and 18-25 of Block 9 of Riverton were acquired by a single owner and a trucking operation was established on the property. The Becker Family owned the property at the time it was developed with the current service garage, distribution warehouse, loading dock, and related improvements in 1975. The Property was annexed into Tukwila in 1989 as part of the Riverton Annexation. Ordinance no. 1479 amended the Comprehensive Land Use Policy Plan Map and applied the Heavy Industry designation to Lots 1-4 and 22-25 of Block 9. Lots 18-21 were designated Low Density Residential. In 1995 the City adopted the 1995 Comprehensive Land Use Plan and Map for the City of Tukwila and a new zoning map. Lots 18-25 appear to have been consolidated between the Riverton Annexation in 1989 and the zoning map adoption in 1995. The lot consolidation did not affect the zoning boundary, resulting in a split -zoned lot. The zoning boundary was not changed in 1995 and the property remains split -zoned today. The existing trucking operation is nonconforming to the LDR use requirements in Table 18-6, TMC 18.09, and TMC 18.10.020. 4 Vicinity Information The Property is close to SR 599 freeway access. Land Use The land uses around the Property reflect the zoning. The property immediately west is developed with a single family home. Across S 128th St. to the south is Tukwila School District's bus parking lot and transportation building, zoned Neighborhood Commercial Center (NCC). Properties across E Marginal Way S to the southeast are also zoned NCC and are currently developed with single-family homes. Immediately to the north of the Property is a C/LI property containing a former single-family home that has been converted into a commercial structure. Additional single-family homes are located northwest of the Property on land that is zoned Low Density Residential (LDR). Figure 3 - Land Use Map Existing Regulations Current Conditions The Property was annexed into the City of Tukwila on April 15, 1989, as part of Ordinance No. 1508. A zoning map included with this ordinance confirmed the zoning classifications applied in Ordinance No. 1480 (Effective Date October 18, 1988) for the subject property. The Property was originally composed of multiple lots containing "R-1: Single Family Residence 7200" and "C-M: Industrial Park" zoning designations. In 1995, the City adopted a new Comprehensive Land Use Plan, Zoning Code, and Zoning Map. This new zoning code amended the number and names of zoning districts in the city: R-1 became LDR and C-M became C/LI. Between 1989 and 1995, the Tots composing the Property appear to have been 5 consolidated. However, the zoning boundary was not changed as part of either the lot consolidation or the 1995 Comprehensive Plan adoption, and the Property remains split -zoned today. The existing trucking operation is nonconforming on the LDR-portion of the Property pursuant to the use provisions in Table 18-6, TMC 18.09, and TMC 18.10.020. The trucking operation was in active, continual operation prior to the lot consolidation and annexation into the City of Tukwila. TMC 18.70 allows legally established nonconforming uses to continue and sets forth limitations on any expansion of nonconforming uses. Public Comments Notice was sent to property owners and tenants within 500' of the Property and agencies with jurisdiction. A Type 5 public meeting was held on April 17, 2019, and three nearby property owners attended. One residential property owner requested that a greater noise and visual buffer be provided on the west side of the property, to limit hours of operations to reasonable hours, to reduce the amount of visual impairment at the southeast corner of the lot for drivers pulling on to E.Marginal Way S, and to limit street parking to 5 hours a day. Two residential property owners expressed concern via email about the past contamination of the Property and potential impacts to the stream, as well the need for vegetated buffering around the site especially along the western portion adjacent to neighboring homes. They also expressed a desire to see the stream improved for fish habitat. Comprehensive Plan and Zoning Map Amendment Criteria The Applicant's response to the decision criteria is attached as Attachment B. 1. The proposed amendment to the [Comprehensive Plan and] zoning map is consistent with the goals, objectives, and policies of the Comprehensive Plan Four broad -reaching objectives are the basis for the elements, goals and policies for Tukwila's Comprehensive Plan. The Comprehensive Plan's primary objective is preserving and enhancing Tukwila's neighborhoods. The Community Image and Identity Element has the following goal: A community of inviting neighborhoods and vibrant business districts. (Goal 1.1) The policies then speak about recognizable boundaries. Strengthen the image and character of Tukwila's distinct areas and neighborhoods (Policy 1.1.2) Applicant Response: The subject property takes primary access from E Marginal Way S and is part of a node of C/LI and Neighborhood Commercial (NCC) zoning along this arterial that is not one lot deep (except on the subject parcel). Rezoning the west side of 6 the subject property to be consistent with this district will strengthen the image and character of the node by clarifying the uses allowed on the site, creating a consistent expectation about development on the property, and establishing clear definition between the residential neighborhood to the west and the commercial/light industrial uses along E Marginal Way S. Staff Response: The Zoning District boundary is not clearly identifiable in the neighborhood. The Property is split -zoned, leading to a lack of clarity in the use and development. Rezoning the Property would help create a consistent expectation about land use on the lot and will clearly define the residential neighborhood as distinct from the commercial and industrial uses along E Marginal Way S. The Natural Environment Element has the following goals: The City's air, land, and water resources are restored and protected for future generations. (Goal 4.1) Goal 4.4 Water resources that function as a healthy, integrated system; provide a long-term public benefit from enhanced environmental quality; and have the potential to reduce public infrastructure costs. Watercourses and their buffers, ...., are protected from encroachment and degradation and improved through mitigation, enhancement, and restoration projects. (Goal 4.6) Applicant Response: The proposed rezone will clarify applicable use requirements and position the property for redevelopment, which presents and opportunity to implement forward -thinking development techniques such as Low Impact Development (LID) and environmental enhancement and remediation (if necessary) consistent with this goal. The City has adopted a Critical Areas Ordinance in TMC Chapter 18.45 "Environmentally Sensitive Areas." The purpose of this chapter is to protect the environment, human life, and property; identify and classify ecologically sensitive areas; and protect these areas and their functions while allowing for reasonable use of public and private property. New development on the subject parcel is require to comply with applicable critical areas requirements to minimize development impacts using best available science. The east fork of Riverton Creek flows across the northwest corner of the property through and underground pipe, and redevelopment of the property presents an opportunity to address this sensitive area. The subject property has already had some environmental remediation and cleanup related to its historic use as a trucking facility. Contamination from leaking underground storage tanks was addressed in 1999, and periodic review by the Department of Ecology confirms that the remedial actions continue to eliminate exposure to contaminated soils by ingestion and contact. Work was performed under the Model Toxics Control Act and the Voluntary Cleanup Program (codified in Chapter 173-340 WAC). A restrictive covenant is recorded on the property documenting the contamination and cleanup work and prohibiting work that could disturb contaminated soils without review and approval by the Department of Ecology. Future work on the property is required to coordinate with Department of Ecology and address the restrictive covenant on the property. Substantial disturbance of the property could result in expanded cleanup efforts to eliminate contamination. Staff Response: Redevelopment of the Property as a commercial or light industrial use would require any development/use to be located outside of the stream buffer areas. The existing condition of a truck parking area built over the watercourse would be improved if the parking area is removed and the western portion of the Property restored as a natural area for the watercourse. The City has adopted a Critical Areas Ordinance in TMC Chapter 18.45, "Environmentally Sensitive Areas." New development on the Property is required to comply with applicable critical areas requirements to minimize development impacts using best available science. The east fork of Riverton Creek flows across the northwest corner of the property through an underground pipe (see Figure 4), and redevelopment of the property presents an opportunity to upgrade this sensitive area. TMC 18.45.110.B.5.g requires that "On properties being developed or re -developed, or when stream crossings in public or private rights -of -way are being replaced, existing culverts that carry fish -bearing watercourses or those that could bear fish (based on the criteria in WAC 222-16-031, Washington Forest Practices Rules and Regulations), shall be upgraded to meet the standards in the WDFW manual "Design of Road Culverts for Fish Passage" (2003 or as updated) if technically feasible." If daylighting or upgrading of the stream is proven to be technically infeasible, the western portions of the Property located within the stream buffer area could be planted with native plants that improves the original condition in species diversity and density, and all existing durable surfaces within the stream buffer could be removed to protect the Creek and its buffer. The rezone proposal provides an opportunity to improve the existing stream and buffer from its current condition which complies with the City's comprehensive plan goals. 8 Figure 4 — Sensitive Areas Map. Type II stream in pipe flows through northwest corner of slte; 100' buffers begin from where stream is not in pipe. A relevant Economic Development Element policy is: Promote and preserve economic use of industrial lands outside the MIC through appropriate buffering requirements and use restrictions. (Economic Development Policy 2.1.16) Applicant Response: The Subject Site is located just south of the MIC boundary, along E Marginal Way S, and has been in continual use as a commercial/light industrial property since prior to annexation in 1989. The proposed rezone supports this policy by preserving the existing C/Ll zoning and expanding it slightly to be consistent with the existing parcel boundary and other similar properties. Additionally, the proposed rezone will eliminate a confusing split -zoning condition, ultimately clarifying how the Subject Site can be used and supporting future redevelopment of the property. The C/LI zone and the landscaping requirements in Table A of TMC 18.52.939 establish appropriate buffering requirements and use restrictions to ensure that commercial and light industrial development is compatible with nearby residential uses. In addition, the requirement for a stream buffer also provides a natural division between the two types of uses. Staff Response: City staff concurs with the applicant's response; increased setback and screening requirements are set forth for C/LI properties located adjacent to any residential property including those zoned LDR. Additionally, the property has been in continuous use as a truck terminal since before annexation into the City of Tukwila, and this proposal will work to preserve a historically industrial land while enhancing the buffers for surrounding properties. Overall, this proposal is consistent with the goals, policies and objectives of the Comprehensive Plan. 9 and prohibiting work that could disturb contaminated soils without review and approval by the Department of Ecology. Future work on the property is required to coordinate with Department of Ecology and address the restrictive covenant on the property. Substantial disturbance of the property could result in expanded cleanup efforts to eliminate contamination. Staff Response: Redevelopment of the Property as a commercial or light industrial use would require any development/use to be located outside of the stream buffer areas. The existing condition of a truck parking area built over the watercourse would be improved if the parking area is removed and the western portion of the Property restored as a natural area for the watercourse. The City has adopted a Critical Areas Ordinance in TMC Chapter 18.45, "Environmentally Sensitive Areas." New development on the Property is required to comply with applicable critical areas requirements to minimize development impacts using best available science. The east fork of Riverton Creek flows across the northwest corner of the property through an underground pipe (see Figure 4), and redevelopment of the property presents an opportunity to upgrade this sensitive area. TMC 18.45.110.B.5.g requires that "On properties being developed or re -developed, or when stream crossings in public or private rights -of -way are being replaced, existing culverts that carry fish -bearing watercourses or those that could bear fish (based on the criteria in WAC 222-16-031, Washington Forest Practices Rules and Regulations), shall be upgraded to meet the standards in the WDFW manual "Design of Road Culverts for Fish Passage" (2003 or as updated) if technically feasible."

The rezone proposal provides an opportunity to improve the existing stream and buffer from its current condition which complies with the City's comprehensive plan goals. 8 Figure 4 — Sensitive Areas Map. Type 1I stream in pipe flows through northwest corner of site; 100' buffers begin from where stream is not in pipe. A relevant Economic Development Element policy is: Promote and preserve economic use of industrial lands outside the MIC through appropriate buffering requirements and use restrictions. (Economic Development Policy 2.1.16) Applicant Response: The Subject Site is located just south of the MIC boundary, along E Marginal Way S, and has been in continual use as a commercial/light industrial property since prior to annexation in 1989. The proposed rezone supports this policy by preserving the existing C/LI zoning and expanding it slightly to be consistent with the existing parcel boundary and other similar properties. Additionally, the proposed rezone will eliminate a confusing split -zoning condition, ultimately clarifying how the Subject Site can be used and supporting future redevelopment of the property. The C/LI zone and the landscaping requirements in Table A of TMC 18.52.939 establish appropriate buffering requirements and use restrictions to ensure that commercial and light industrial development is compatible with nearby residential uses. In addition, the requirement for a stream buffer also provides a natural division between the two types of uses. Staff Response: City staff concurs with the applicant's response; increased setback and screening requirements are set forth for C/LI properties located adjacent to any residential property including those zoned LDR. Additionally, the property has been in continuous use as a truck terminal since before annexation into the City of Tukwila, and this proposal will work to preserve a historically industrial land while enhancing the buffers for surrounding properties. Overall, this proposal is consistent with the goals, policies and objectives of the Comprehensive Plan. 9 2. The proposed amendment to the Zoning Map is consistent with the scope and purpose of this title (the Zoning Code) and the description and purpose of the zone classification applied for. Pursuant to TMC 18.30.010, the C/LI district "is intended to provide for areas characterized by a mix of commercial, office, or light industrial uses. The standards are intended to promote viable and attractive commercial and industrial areas." The properties around the intersection of E Marginal Way S and S 128th St are a mix of commercial and industrial uses consistent with the purpose of the C/LI zone, including the Property which is used as a trucking facility. The Property is also similar in character to commercially and industrially zoned property in the immediate vicinity. Properties with frontage along E Marginal Way S tend to be zoned and used as commercial and industrial businesses. Uses transition from much more intense industrial activities with large warehouses and significant vehicular traffic in the north to lighter industrial and commercial uses further south. E Marginal Way S is a high -volume arterial with excellent connectivity to local and regional transportation networks. Along E Marginal Way S, the C/LI zoning serves as a logical transition between the Manufacturing Industrial Center (MIC) to the north and the Neighborhood Commercial Center (NCC) zoning to the south. The Property has been in continual operation as a trucking facility since prior to its annexation into the City of Tukwila. A trucking facility is nonconforming on the LDR-portion of the site. TMC 18.70 allows legally established nonconforming uses to continue and sets forth limitations on any expansion of nonconforming uses. The proposed rezone would bring the nonconforming portion of the trucking facility (that portion located in the LDR zone) into conformance with zoning code. 3. There are changed conditions since the previous zoning became effective to warrant the proposed amendment to the Zoning (and Comprehensive Plan) Map The Property was annexed into the City of Tukwila in 1989 and was originally composed of multiple Tots containing "R-1: Single Family Residence 7200" and "C-M: Industrial Park" zoning designations. Since then, the number and names of the zoning districts in the City were subsequently amended, and the Tots composing the Property appear to have been consolidated. However, the zoning boundary was not changed as part of either the lot consolidation or the 1995 Comprehensive Plan adoption, and the property remains split -zoned today. In the area near the subject property, single-family homes are mainly located away from E Marginal Way 5 to the west and to the east. E Marginal Way 5 is largely composed of commercial and industrial uses stretching from SR-599 to north down to the intersection of E Marginal Way S and 40th Ave S to the south. Since the 1995 Comprehensive Plan adoption the surrounding area has seen a marked increase in commercial and light industrial development. Parcel 7345600675 immediately north of the Property contains a former single-family home in the C/LI district that was converted to office use in 2008. Parcel 2384200010 across S 128th St to 10 the south was developed in 2017 with a small office structure for Tukwila School District's bus drivers and general faculty. Parcel 7340600774 further south was developed as a mixed -use apartment building with ground floor retail in 2008. To the north on parcel 7340600480 a former Group Health office building is currently being replaced with King County Metro's South Interim Bus Base which will contain offices, a bus maintenance garage, and parking for approximately 160 coaches. 7345600675 2008) 23842.00010 (2017) 1117340600774(2008) Figure 5: Commercial/Industrial parcels with developments since 1995. The proposed Comprehensive Plan Amendment to reclassify the entire parcel as Commercial Light Industrial will eliminate a split -zone condition, bring a legally established non -conforming use into conformance with the Tukwila Municipal Code, and establish zoning more consistent with the conditions along E Marginal Way S. 4. The proposed amendment to the (Comprehensive Plan and) Zoning Map will be in the interest of furtherance of the public health, safety, comfort, convenience, and general welfare, and will not adversely affect the surrounding neighborhoods, nor be injurious to other properties in the vicinity in which the subject property is located. Environmental remediation has been completed on the Property and any land -disturbing activities are required to be coordinated with Department of Ecology to ensure any remaining 11 contamination is appropriately remediated. A restrictive covenant has been recorded on the property to limit activities on the site to protect the environment and the public health, safety, and welfare. In addition and as discussed above, upgrades to the Riverton Creek and related mitigation would improve the natural area and improve the buffer between adjacent Low Density Residential properties to the north and west over the existing site conditions in the interest of general health, safety and welfare of the public. Development requirements set forth in TMC Chapter 18.30, "Commercial/Light Industrial (C/LI) District," establish appropriate buffers, increase setbacks compared to those required under the LDR zone, and require landscaping screening to separate the C/LI uses from residential development. Such requirements would further the public health, safety, comfort, convenience and general welfare of the surrounding neighborhoods. The request would extend the boundary line for the C/LI district to the western property boundary. Below is a table comparing the setback and height requirements for the two zones: LDR C/LI (when w/in 50 ft of LDR) Setbacks Front 20' 25' Second front 10' 15' Sides 1" floor 5' 15' 2nd floor 5' 20' 3rd floor 5' 30' Rear 10' 15-30' Height 30' 45' Standards in the C/LI zone are in place to minimize impact and any nuisance. No on -site hazardous substance processing, handing, or storage is allowed unless clearly incidental to the permitted use and is subject to state siting criteria. Performance standards are also in effect in the CLI for air quality, noise and SEPA compliance. II. CONCLUSIONS 1) Consistency with Comprehensive Plan • The proposed rezone is consistent with the Comprehensive Plan objectives, goals and policies which acknowledge the need to maintain and support commercial/industrial lands outside of the Manufacturing Industrial Center in a way that reduces impacts on adjacent properties and/or residential neighborhoods. 2) Consistency with Zone • The requested map change to C/LI for the entire parcel would remove a split -zone property from the City zoning map. 12 • The amendment would terminate partially -nonconforming land use on the Property that has been operating in the neighborhood since before annexation into the City of Tukwila. • Specific redevelopment plans will undergo environmental, design review and building permit review. 3) Changed conditions • The property has been split -zoned since at least 1995. Since that time properties along E Marginal Way S have been developed with a combination of commercial and Tight industrial uses, including but not limited the King County Metro South Interim Bus Base. The amendment will eliminate a split -zone condition, bring a legally established non -conforming use into conformance with standards for the Commercial/Light Industrial district in the Tukwila Municipal Code, and establish zoning more consistent with the conditions along E Marginal Way S. Benefit to community • The community will benefit through redevelopment of the site that will conform with development regulations set forth in the Tukwila Municipal Code, including but not limited to landscaping, setbacks, enhanced buffers from residential areas, and a significantly improved environment for the Type 2 stream that runs adjacent to and through the western portion of the Property. III. RECOMMENDATION Staff recommends approving the rezone request to change the existing Low Density Residential (LDR) zoning to Commercial/Light Industrial (C/LI), with corresponding Comprehensive Plan and Zoning map amendments, subject to the following conditions: 1. Within six years of the effective date of this ordinance, property owner shall implement a City approved plan to daylight (or, if daylighting is not feasible, to upgrade the stream culvert for) the Type II stream located within a pipe on the western half of the property. The plan shall meet the standards in the WDFW manual "Design of Road Culverts for Fish Passage" (2003 or as updated). If daylighting or upgrading of the stream culvert is proven to be technically infeasible, the western portions of the Property located within the stream buffer area shall be planted with native plants that improves upon the original condition as part of a planting plan to be approved by the City. Additionally, the property owner shall remove all existing impervious surfaces located within the stream buffer within the six -year time frame. 2. Within 180 days of the passage of this ordinance, the applicant shall record against the site a covenant or other document, approved by the City, requiring compliance with Condition 1. 3. Failure to comply with Conditions 1 and 2 shall cause the change to the Zoning Map to be null and void, the subject property shall revert to the zoning immediately preceding passage of this ordinance, and any non -conforming use shall cease to exist and any subsequent use shall conform to the regulations specified by the Tukwila Municipal Code for the district in which such use is located. 13 a- ••.:1IbiL \ \ - STORM DRAIN EASEMENT ; -4 ••aa ee‘e' : 4111,.11Lr lt .811 e4t s: •• • 41" I 1,1' • I L.

A contiguous parcel owned by the same property owner (no. 7345600685) and used as part of the development on parcel no. 7345600766 is already zoned C/LI and is not included in this request. Summary of the Reason for the Request As part of its long-range plans for growth of transit service in the region, Metro needs to purchase additional property for indoor mechanical training activities and construction offices. For that purpose, Metro is seeking to purchase property at 12677 E Marginal Way S (parcel no. 7345600766) and 12633 E Marginal Way S (parcel no. 7345600685) from Blue Nile Holdings, LLC (see Figure 1). 0 4or Parcel no 7345600766. subject of request bunk;', • 7 ,3, O'Vbe, n40 Parcel no. 7345600685. excluded from rcquesl 5;1 ,13‘21` 411%411016. Figure 1: Becker Transfer properties outlined in red. Source: King County iMap. The smaller parcel is zoned Commercial Light Industrial (C/LI). The larger parcel is split -zoned; the eastern portion fronting on E Marginal Way S is zoned C/LI and the western portion is zoned Low Density Residential (LDR). The site is ideal for Metro's intended future use of the site, but the split -zoned condition creates uncertainty about how the site could be developed to meet Metro's needs. Metro is pursuing the rezone to rectify this uncertainty for immediate short-term use and potential redevelopment. Metro understands that approval of rezones is considered within the Pagel of15 Rezone West Portion of Parcel No. 7345600766 from OR to C/LI Exhibit F: Project and Decision Criteria Narrative larger planning context and must be consistent with the vision for Tukwila, and for the surrounding neighborhoods. Metro believes that the rezone is consistent with the vision and character for this area, and that in the long term will provide opportunities for enhancement of the boundary between the residential and commercial areas. The use of the site since at least 1975 has been light industrial, specifically a truck terminal use with accessory warehouse and parking. Truck terminal use is nonconforming to the existing LDR zoning and conforming to the existing C/LI zoning (see Figure 2). Parcel no. 7345600766, subject of request i Parcel no. 7345600685, excluded from request Figure 2. Excerpt of City of Tukwila Comprehensive Plan & Zoning Map, subject properties outlined in red. Purple zoning is C/LI, yellow zoning is LDR. Split -zoning is discouraged by the City of Tukwila's Comprehensive Plan and tends to create uncertainty for future development or redevelopment. A history of the land use and zoning on the property is included in this application. Rezoning the property will strengthen the boundary between the LDR zone to the west and C/LI zone along E Marginal Way S. It will provide certainty for Metro by ensuring that the office uses can continue and that the site can be developed efficiently for those uses. To the extent that rezoning will remove confusion around applicability of zoning to the site and its nonconforming status, future redevelopment would be encouraged and that would offer opportunities to make the site development more conforming to existing regulations. Metro's Intended Use of the Site and a Conceptual Plan If the rezone is approved, Metro's current thoughts for use of the site are for office and indoor training activities that currently occur on the nearby South Base facilities. Metro has provided a drawing of what a potential layout for office and training use could look like (see Exhibit I), but is not seeking any review or approval of that layout at this time. Before Metro can realistically create a plan for specific uses that addresses applicable development standards, the rezone would need to be approved. Any future changes to the site to allow redevelopment would be subject to review by the City of Tukwila through Design Review because of the proximity to the LDR zone. At the time of a proposed redevelopment of the site, Metro would work with the City of Tukwila to ensure compliance with site development standards. Site Description The properties are collectively identified in the King County Assessor's records as "Becker Transfer." Parcel no. 7345600766 is approximately 1.64 acres (71,440 square feet) in size. Parcel no. 7345600685 is approximately 0.26 acres (11,490 square feet) in size. Parcel no. 7345600766 is split -zoned: the eastern portion fronting on E Marginal Way S is zoned Commercial/Light Industrial (C/LI), and the western portion is zoned Low Density Residential (LDR). Parcel no. 7345600685 is zoned C/LI. Refer to Figure 2. Page 2 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/Ll Exhibit F: Project and Decision Criteria Narrative The parcels are used as a single property that serves as the base of operations for Blue Nile Trucking, LLC. The site is accessed by one driveway on E Marginal Way S and two driveways on S 128th Street. Permanent structures include a service garage, distribution warehouse, loading dock, and fuel pump built in 1975; the remainder of the parcels are paved and/or graveled. Vehicles and trailers of varying sizes are stored along the north and west property lines. Surrounding land uses include a mix of single-family residential, commercial, and industrial. The east branch of Riverton Creek is present in the vicinity of and on the property. The creek flows through an open ditch and onto the northwest corner of the property for approximately 25 feet before entering an underground pipe. The creek flows through approximately 195 feet of underground pipe and daylights into another open ditch (see Exhibit G). The existing stream and buffer are significantly degraded due to undergrounding and surrounding development. Request Requests for changes in zoning are made pursuant to Chapter 18.84 TMC. Granting a rezone and accompanying Comprehensive Plan map change is allowed when consistency with the following criteria can be demonstrated: 1. The proposed amendment to the Zoning Map is consistent with the goals, objectives, and policies of the Comprehensive Plan. The proposed amendment is consistent with the applicable goals, objectives, and policies of the City's Comprehensive Plan. The proposed change from LDR to C/LI will clarify the boundary between the two zones at the subject location; facilitate future redevelopment consistent with the character of E Marginal Way S; and eliminate a nonconformity. Community /mane and Identity Element The Community Image and Identity element of the Comprehensive Plan establishes a framework to celebrate the City's history and environment, build on diversity, foster civic engagement, and accommodate growth that furthers the community's vision.' The proposed rezone will contribute to this framework by improving consistency of the property's designation with the following goals and policies: • Goal 1.1— A community of inviting neighborhoods and vibrant business districts. The subject property is accessed from E Marginal Way S and S 128th Street. The parcel is situated at the boundary between commercial and industrial uses on E Marginal Way S and residential uses further west and south in the area. The property is split - zoned, leading to a lack of clarity in the use and development of the site. Rezoning the property will help create a consistent expectation about land use on the lot and will clearly define the residential neighborhood as distinct from the commercial and industrial uses along E Marginal Way S. The proposed rezone will expand the C/LI zoning boundary to be consistent with the property boundary and the current use of the property. The proposed rezone is not expected to impact the character of the residential area for several reasons. The residential neighborhood has grown up around this industrial use that has been in continual operation since at least 1975 (see response to criterion 2, below, for additional property history). Additionally, given that a portion of the property is already zoned C/Ll, 1 Tukwila Comprehensive Plan, Community Image and Identity Element, page 1-2. Page 3 of 15 Rezone West Portion of Parcel No. 7345600766 from LOR to C/LI Exhibit F: Project and Decision Criteria Narrative the rezone will not invite new uses that are not already allowed adjacent to the residential neighborhood. Finally, the east branch of Riverton Creek, located along the west side of the subject property and approximately coincident with the proposed rezone, serves as a natural boundary or buffer between different land uses. The rezone will encourage the potential redevelopment of the site which may provide an opportunity to enhance the aesthetics of the site, clearly define the boundary to adjacent land uses, and provide capital investment into the neighborhood. • Policy 1.1.2 — Strengthen the image and character of Tukwila's distinct areas and neighborhoods. The subject property takes primary access from E Marginal Way S and is part of a node of C/LI and Neighborhood Commercial (NCC) zoning along this arterial that is one lot deep (except on the subject parcel) (see Figure 3). Rezoning the west side of the subject property to be consistent with this district will strengthen the image and character of the node by clarifying the uses allowed on the site, creating a consistent expectation about development on the property, and establishing clear definition between the residential neighborhood to the west and the commercial/light industrial uses along E Marginal Way S. e C/L Figure 3. Excerpt of City of Tukwila Comprehensive Plan & Zoning Map, I subject properties outlined in red. Economic Development Element The overall goal of the Economic Development element is to enhance the economic well- being of the community, including stimulating economic improvement for individual businesses and the community. The proposed rezone is consistent with this purpose and addresses the following goals and policies: • Goal 2.1— Tukwila has a strong role as a regional business and employment center which allows it to enhance and promote the community's well-being. The proposed rezone is supportive of the continued business use of the subject property (and, as described above, is not detrimental to the residential neighborhood to the west). Page 4 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative The rezone will eliminate a confusing split -zoning condition, which will clarify how the property can be used and support future redevelopment of the site as a commercial/light industrial property similar to other uses along E Marginal Way S. This contributes to Tukwila's image as a regional business center. The proposal is consistent with policies intended to implement this goal, as described below. • Policy 2.1.16 — Promote and preserve economic use of industrial lands outside the Manufacturing Industrial Center (MIC) through appropriate buffering requirements and use restrictions. The subject property is located just south of the MIC boundary, along E Marginal Way S, and has been in continual use as a commercial/light industrial property since before the neighborhood was annexed in 1989. The proposed rezone supports this policy by preserving the existing C/LI zoning and expanding it slightly to be consistent with the existing parcel boundary and other similar properties. Additionally, the proposed rezone will eliminate a confusing split -zoning condition, ultimately clarifying how the property can be used and supporting future redevelopment of the property. The C/LI zone and the landscaping requirements in Table A of TMC 18.52.030 establish appropriate buffering requirements and use restrictions to ensure that commercial or light industrial development is compatible with nearby residential uses. Table A in the code shows the standard buffer depths of 6 feet and 0 feet for side and rear yards, respectively, are increased to 15 feet, and the intensity of buffer plantings raised from Type II to Type III for new development within 50 feet of a residential zone. Design review is required for new development within 300 feet of a residential zone. These standards are protective of residential development and ensure commercial and light industrial development is compatible with surrounding land uses while also promoting viable and attractive commercial and industrial areas. In addition, the requirement for a stream buffer also provides a natural division between the two types of uses. • Policy 2.1.17 — Include standards in the development regulations for industrial uses that adequately mitigate potential adverse impacts on surrounding properties and public facilities and services. In addition to the use and buffering requirements described above, development in the C/LI zone is subject to performance standards, including standards adopted by the Puget Sound Air Pollution Control Agency for odor, dust, smoke, and airborne pollutants; noise standards adopted in TMC Chapter 8.22; and State and Federal standards for water quality and hazardous materials. Review under the State Environmental Policy Act (SEPA) provides substantive authority to mitigate potential adverse environmental impacts. Natural Environment Element The Natural Environment element guides future development in a manner to protect the community's environment, improve quality of life within the City, and protect residents from natural hazards. The proposed rezone addresses the following goals and policies in this element: • Goal 4.1— The City's air, land, and water resources are restored and protected for future generations and Policy 4.1.5 — Develop and implement programs that encourage Tukwila residents and businesses to take active measures to protect Page 5 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F. Project and Decision Criteria Narrative and enhance Tukwila's natural environment. Such measures could include the use of Low Impact Development (LID) techniques, natural streambank restoration, non -toxic lawn care, composting, and recycling, among others. The proposed rezone will clarify applicable use requirements and position the property for redevelopment, which presents an opportunity to implement forward -thinking development techniques such as Low Impact Development (LID) and environmental enhancement and remediation (if necessary), consistent with this goal. The City has adopted a Critical Areas Ordinance in TMC Chapter 18.45, "Environmentally Sensitive Areas." The purpose of this chapter is to protect the environment, human life, and property; identify and classify ecologically sensitive areas; and protect these areas and their functions while allowing for reasonable use of public and private property. New development on the subject parcel is required to comply with applicable critical areas requirements to minimize development impacts using best available science. The east fork of Riverton Creek flows across the northwest corner of the property through an underground pipe, and redevelopment of the property presents an opportunity to address this sensitive area. The subject property has already had some environmental remediation and cleanup related to its historic use as a trucking facility. Contamination from leaking underground storage tanks was addressed in 1999 and periodic review by the Department of Ecology confirms that the remedial actions continue to eliminate exposure to contaminated soils by ingestion and contact. Work was performed under the Model Toxics Control Act and the Voluntary Cleanup Program (codified in Chapter 173-340 WAC). A restrictive covenant is recorded on the property documenting the contamination and cleanup work and prohibiting work that could disturb contaminated soils without review and approval by the Department of Ecology. Future work on the property is required to coordinate with the Department of Ecology and address the restrictive covenant on the property. Substantial disturbance of the property could result in expanded cleanup efforts to eliminate contamination. • Goal 4.4 — Water resources that function as a healthy, integrated system; provide a long-term public benefit from enhanced environmental quality; and have the potential to reduce public infrastructure costs. The east fork of Riverton Creek flows across the northwest corner of the property primarily through an underground pipe. Approximately 25 feet of the creek flows through an open ditch before entering an underground pipe, where it travels for approximately 195 feet before daylighting into another open ditch (see Exhibit G). Redevelopment encouraged by the proposed rezone would provide opportunities to address this water resource, including improving surface water quality and quantity, restoring degraded buffer areas, and/or daylighting the stream. All of these opportunities would improve the health of water resources at and downstream of the subject stream and provide public benefits. • Goal 4.6 — Watercourses and their buffers, wetlands and wetland buffers protected from encroachment and degradation and improved through mitigation, enhancement restoration projects. The east fork of Riverton Creek has a significantly degraded buffer and is low - functioning due to being undergrounded in the property's vicinity. Redevelopment Page 6 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative encouraged by the proposed rezone would provide an opportunity to improve buffer and watercourse conditions. • Policies 4.6.1 through 4.6.4 — Policies related to regulation of land use and development, mitigation requirements, and sensitive areas studies. The City of Tukwila has adopted a comprehensive Critical Areas Ordinance (TMC Chapter 18.45) to regulate development in and adjacent to sensitive areas. The regulations ensure development is located and designed to achieve no net loss of sensitive areas functions through mitigation sequencing and compensatory mitigation. Redevelopment encouraged by the proposed rezone is required to comply with these regulations and provides an opportunity to improve conditions for the largely undergrounded stream. • Goal 4.7 — The water quality in Tukwila's wetlands, watercourses, fish and wildlife habitat areas and the Green/Duwamish River is improved over time. The stream has a significantly degraded buffer and is low -functioning due to being undergrounded at and in the property's vicinity. Redevelopment encouraged by the proposed rezone would provide an opportunity to improve buffer and watercourse conditions. • Policy 4.7.1— Improve surface water management and ensure provision of water quality treatment where required. Redevelopment encouraged by the proposed rezone would be required to conform to applicable stormwater and surface water management techniques and the King County Surface Water Design Manual 2016 (2016 KCSWDM) adopted by the City of Tukwila. • Goal 4.8 — Surface water generated by urban development does not exceed pre - development discharge rates The subject parcel is almost entirely covered with impervious surfaces. While the re- zone application will not modify the percentage of impervious surfaces on the site, future redevelopment encouraged by the proposed rezone will be required to comply with development standards that will reduce the amount of impervious surface coverage and detain, treat, and discharge surface water. Residential Neighborhoods Element The Residential Neighborhoods element focuses on neighborhood sustainability to preserve and enhance the sense of community in each residential neighborhood. The proposed rezone will occur adjacent to an existing single-family residential neighborhood. Because the rezone would affect land currently zoned for single-family residential use, Goal 7.1 and Policy 7.1.1 appear to be most applicable to the proposed rezone and are addressed below: • Goal 7.1— Residential Land Use Pattern: A land use pattern that encourages a strong sense of community by grouping compatible and mutually supportive uses and separating incompatible uses. The existing property is split -zoned, with the western portion zoned LDR and the eastern portion zoned C/LI. Since at least 1975, the property has been used for trucking operations, which is nonconforming to use requirements in the LDR zone. The split - zone condition creates confusion in the application of development requirements and therefore does not tend to encourage a sense of community at that location. In fact, it Page 7of15 Rezone West Portion of Parcel No. 7345600766 from LDR to C21 Exhibit F: Project and Decision Criteria Narrative tends to blur the boundary between the residential community and commercial operations. The proposed rezone will clarify the expectation for the use and development of the property in the future, which will solidify the character of the neighborhood in the immediate vicinity of the rezone and exclude incompatible uses from the LDR zone. The east branch of Riverton Creek creates a natural boundary to define residential uses from the commercial and industrial uses fronting along E Marginal Way S. • Policy 7.1.1— Maintain a comprehensive land use map that supports the preservation and enhancement of single-family and stable multi -family neighborhoods; eliminates incompatible land uses; and clearly establishes applicable development requirements through recognizable boundaries. The split -zone condition is confusing and does not provide a clear and recognizable boundary between land uses. The proposed rezone will establish a recognizable boundary and eliminate a confusing split -zone condition for the subject property. It will also make the boundary of the C/LI node around the intersection of E Marginal Way S and S 128th Street consistent on this parcel by expanding the C/LI zone to the property boundary. The rezone is likely to encourage redevelopment of the site and meet applicable development regulations which are designed to enhance the buffer between commercial and residential uses. 2. The proposed amendment to the Zoning Map is consistent with the scope and purpose of TMC Title 18, "Zoning Code," and the description and purpose of the zone classification applied for. The proposed rezone is broadly consistent with the scope and purpose of Title 18 TMC, "Zoning Code." The zoning code implements the City's Comprehensive Plan and, as discussed above, the proposed rezone is consistent with numerous goals and policies therein. More specifically, the proposed rezone is consistent with the description and purpose of the C/LI zone. Pursuant to TMC 18.30.010, the C/LI district "is intended to provide for areas characterized by a mix of commercial, office, or light industrial uses. The standards are intended to promote viable and attractive commercial and industrial areas." The properties around the intersection of E Marginal Way S and S 128th Street are a mix of primarily commercial and industrial uses consistent with the purpose of the C/LI zone, including the subject property which is used as a trucking facility. The subject property is similar in character to commercially- and industrially -zoned property in the immediate vicinity (see Figure 4). Properties with frontage along E Marginal Way S tend to be zoned and used as commercial and industrial businesses. Uses transition from much more intense industrial activities with large warehouses and significant vehicular traffic in the north to lighter industrial and commercial uses further south. E Marginal Way S is a high -volume arterial with excellent connectivity to local and regional transportation networks. Along E Marginal Way S, the C/LI zoning serves as a logical transition between the Manufacturing Industrial Center (MIC) and industrial zoning (L) to the north and the neighborhood commercial zoning (NCC) to the south (see Figure 3, above). Page 8 of 15 • t. i• Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F. Project and Decision Criteria Narrative • t Figure 4: Vicinity map, subject property outlined in red. Source: King County iMap. LDR zoning is not appropriate for the subject site. The purpose of the LDR zone is "to provide low -density family residential areas together with a full range of urban infrastructure services in order to maintain stable residential neighborhoods, and to prevent intrusions by incompatible land uses." The property has been in continual operation as a trucking facility since prior to its annexation into the City of Tukwila. A trucking facility is nonconforming to the use provisions of the LDR zone. Chapter 18.70 TMC, "Nonconformity," allows legally established nonconforming uses to continue and sets forth limitations on any expansion of nonconforming uses. A lapse or change in the use would cause abandonment of rights to nonconformity and any new use established is required to comply with current use regulations. In this way, TMC Chapter 18.70 seeks to reduce nonconformity as much as possible. The proposed rezone would bring the nonconforming portion of the trucking facility (that portion located in the LDR zone) into conformance with the zoning code. (REMAINDER OF PAGE INTENTIONALLY LEFT BLANK) Page 9 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative 3. There are changed conditions since the previous zoning became effective to warrant the proposed amendment to the Zoning Map. Conditions have changed considerably since the previous zoning became effective. The proposal to rezone the western portion of parcel no. 7345600766 is reasonable and warranted by the change in circumstances. The subject properties were created in unincorporated King County as Riverton, a replat of a portion of Riverside Interurban Tracts, on June 15, 1906 (see Figure 5).2 Contemporary legal descriptions also refer to this area as "Riverton Addition." Thereafter, Lots 4 and 18-25 of Block 9 of Riverton were acquired by a single owner and a trucking operation was established on the property.3 The Becker family owned the property at the time it was developed with the current service garage, distribution warehouse, loading dock, and related improvements in 1975. Figure 5: Excerpt of Riverton, a replat of part of Riverside Interurban Tracts, recorded in Volume 13 of Plats, Page 36, records of King County, Washington. Image shows all of Block 9, lots forming the subject property outlined in red. NOTE: The orientation of this map is such that north is to the right. Alder Street became S 126th Street and Herkimer Street became S 1281h Street. 2 Plat of Riverton, King County Recording No. 400820, recorded June 15, 1906 in Volume 13 of Plats, Page 36, Records of King County, WA. 3 The Tots were likely purchased by the Becker family, who likely also established the trucking business. Two businesses (Becker Trucking Inc. and Becker Transfer Co.) appear to have grown from this startup. Becker Trucking Inc. has been in operation since 1925 and operates out of Tukwila. Becker Transfer Co. bills itself as a fourth - generation transportation company and operates out of Issaquah. Page 10 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative Riverton was identified as the Riverton Annexation Area by the City of Tukwila. In preparation for annexation, the City adopted ordinances no. 1479, 1480, and 1481 to apply future land use designations and zoning designations to the Riverton area. Ordinance no. 1479 amended the Comprehensive Land Use Policy Plan Map and applied the Heavy Industry designation to Lots 1-4 and 22-25 of Block 9. Lots 18-21 were designated Low Density Residential. Refer to Figure 6. Figure 6: Exhibit B, Attachment H of City of Tukwila Ord. No. 1479. Map shows Riverton Annexation Area boundaries and approved comprehensive land use policy plan designations. Subject property is outlined in red. (REMAINDER OF PAGE INTENTIONALLY LEFT BLANK) Page 11 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/Ll Exhibit F: Project and Decision Criteria Narrative Ordinance no. 1480 amended the zoning map (see Figure 7). Lots 4 and 22-25 of Block 9 were zoned Industrial Park (C-M). Lots 18-21 were zoned Single Family Residence (R-1).

A zoning map was included with this ordinance confirming the zoning classifications applied in ordinance no. 1480 for the subject property (see Figure 8). 1 I R-1 SINGLE FAMILY RESIDENCE 7200 7T--1 SINGLE FAMILY AESIUEri L 12,000 R-4 LOW APARTMENTS RMH MULTIPLE RESIDENCE HIGH DENSITY C-1 COMMUNITY RETAIL BUSINESS mow!

No. 1508. Subject property is outlined in red. Lots 18-21 are zoned R-1 and lots 22-25 are zoned C-M. In 1995, the City of Tukwila began to rewrite its comprehensive plan and zoning code to conform to the recently -adopted Growth Management Act. Ordinance no. 1757 repealed ordinance no. 1479 (among others) and adopted the 1995 Comprehensive Land Use Plan and Map for the City of Tukwila. Ordinance no. 1758 repealed ordinance no. 1481 (among others) and overhauled Title 18 TMC (Zoning Code) and adopted a new zoning map. The zoning code amended the number and names of zoning districts in the city. R-1 became LDR (Low Density Residential) and C-M became C/LI (Commercial/Light Industrial). Lots 18-25 appear to have been consolidated between the Riverton annexation in 1989 and the zoning map adoption in 1995. The lot consolidation did not affect the zoning boundary, resulting in a split -zoned lot. The zoning boundary was not changed in 1995, and the property remains split -zoned today. The existing trucking operation is nonconforming to the LDR use requirements in Table 18-6, TMC 18.09, and TMC 18.10.020. Page 12 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F.- Project and Decision Criteria Narrative The Becker family sold the property in 2005 to C&D Wells, LLC. C&D Wells, LLC sold the property to Blue Nile Holdings, LLC in 2016. Blue Nile Trucking, LLC continues to operate a trucking business from the property. The initial zoning districts applied in 1988-1989 do not appear to have been based on existing conditions or uses. The trucking business was in active operation on the site (having completed improvements in the mid-1970s) at the time. The character of the neighborhood has changed dramatically since zoning was initially applied and continues to evolve to this day. Industrial uses have spread southward from the Duwamish Manufacturing Industrial Center (MIC) and SR-599. As a result, residential development has occurred generally further to the south of the site. E Marginal Way S has become increasingly used for freight and other large vehicles. The evolution of neighborhood character is a changed condition warranting an amendment to the zoning map. The amendment will also eliminate a split -zone condition, bring a legally -established nonconforming use into conformance with the TMC, and establish zoning more consistent with the conditions along E Marginal Way S. 4. The proposed amendment to the Zoning Map will be in the interest of furtherance of the public health, safety, comfort, convenience, and general welfare, and will not adversely affect the surrounding neighborhood, nor be injurious to other properties in the vicinity in which the subject property is located. The request would extend the Commercial/Light Industrial (C/LI) boundary from the approximate center of a parcel to include the full boundaries of the parcel. The C/LI zone allows a number of commercial and light industrial uses that are consistent with the character of E Marginal Way S and nearby industrial uses. Impacts to neighboring residential properties are not anticipated. The residential neighborhood has grown up around the existing commercial/industrial business and the eastern portion of the property is already zoned C/LI. The rezone will not invite new uses that are not already allowed adjacent to the residential area. Development requirements set forth in TMC Chapter 18.30, "Commercial/Light Industrial (C/LI) District," establish appropriate buffers, increase setbacks compared to those required under the LDR zone, require landscaping screening to separate the C/LI uses from residential development, and require a stream buffer from the east branch of Riverton Creek. See Table 1, below, for a comparison of C/LI and LDR dimensional standards. In addition to dimensional requirements, new developments must demonstrate adherence to performance standards, including standards adopted by the Puget Sound Air Pollution Control Agency for odor, dust, smoke, and airborne pollutants; nose standards adopted in in Chapter 8.22 TMC; and State and Federal standards for water quality and hazardous materials. Review under the State Environmental Policy Act (SEPA) provides substantive authority to mitigate potential adverse environmental impacts for future development. Design review is required for any new development within 300 feet of a residential zoning district, which would apply to the subject property. Design review is intended to create well - designed developments that are harmonious with the natural and manmade environments. Review criteria for C/LI developments are related to the following topics: • Relationship of structure to site; • Relationship of structure and site to adjoining area; • Landscaping and site treatment; Page 13 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative • Building design; and • Miscellaneous structures and street furniture. Chapter 18.60 TMC sets forth design review criteria that will protect the residential neighborhood. Design review is completed either administratively by the Director of Community Development or quasi judicially by the Board of Architectural Review. Design review can include conditions of approval to address any potential issues that arise during review. Table 1: Comparison of C/LI and LDR dimensional requirements.

A restrictive covenant has been recorded on the property to limit activities on the site to protect the environment and the public health, safety, and welfare. Conclusion The request, if approved, will rezone the western portion of parcel no. 7345600766 from Low Density Residential (LDR) to Commercial/Light Industrial (C/LI), thus removing the split -zone condition and recognizing the use that has occupied the site since at least the 1970s. Metro is seeking the rezone to facilitate its use of the property. The responses to the decision criteria set forth in TMC 18.84.020 consider the rezone within the larger context of the City's plan for this area, including the full scope of allowable uses within the C/LI zone. The same range of uses is currently allowed on the east portion of the subject property and, with buffers, setbacks, and landscaping requirements, redevelopment to a conforming use would offer opportunities to address site conditions or potential impacts and result in a net benefit to the neighborhood. • The proposal is consistent with the Tukwila Comprehensive Plan, including goals in the Community Image and Identity, Economic Development, Natural Environment, and Residential Neighborhoods elements. The proposal protects existing commercial/light industrial land and positions it for future redevelopment. Redevelopment of the property will occur in conformance with development and environmental regulations, and presents Page 14 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative significant opportunities to protect, enhance, or restore natural features. The rezone will eliminate a split -zone condition and create a clearly defined boundary between residential and non-residential uses. • The proposal is consistent with Title 18 TMC in general and the purpose and intent of the C/LI zone set forth in Chapter 18.30 TMC. The property is in an area characterized by a mix of commercial and light industrial uses and fronts along E Marginal Way S, a busy arterial. • Conditions have changed since zoning was applied in 1988-1989 and updated in 1995. The character of the neighborhood has changed dramatically: industrial uses have expanded to the north, especially with the establishment of the Duwamish Manufacturing Industrial Center (MIC). Residential development has occurred to the south and west, migrating away from the MIC. E Marginal Way S has become increasingly used for freight and other large vehicles. • The proposal is protective of the public health, safety, and welfare and will not adversely affect the surrounding neighborhood. Basic development standards, performance standards, and critical areas requirements mitigate potential adverse impacts to the residential neighborhood. Design review is required when new development occurs within 300 feet of a residential zone, which will ensure the use and site design is fully compatible with existing residential neighborhoods.

I live at 12802 37th Ave S. Tukwila 98168. I have dealt with trucking companies at this site for about 40 years. They have dropped their dock plates, honked their horns, blocked and parked on the street and cut through our residential streets for all of these years. The current owners even had a pitbull that barked for weeks nonstop. Here are some of my proposals and concerns about this project: 1. More trees and a fence blocking the neighbors on the west side of the property from noise and visual distraction. 2. Reasonable limit on hours of operation. 3. Landscape maintanence and indigenous plants. 4.No noise, like air conditoners, generators and trucks. 5. Open up the east entrance to East Marginal and close off the south entrance. 6. Clear the southeast corner of the lot, so that you can see traffic coming from the north when pulling out from 128th. 7. Limit street parking to about 5 hours per day. 8. No Metro vehicles west on 128th.

Be specific in describing the types of changes you want made to the plans. When referencing codes, please identify the actual requirement and plan change needed. The Planning Division review does not supplant each department's ability to administer its own regulations and permits. However, project consistency at the Planning review stage is important to minimize significant later design changes. More than minimal design changes require further Planning Commission review, even if alteration is required to satisfy a City requirement. This further review is typically a minimum 60-day process. Requirements based on SEPA (e.g., not required by an adopted development regulation) MUST identify the impact being mitigated, the policy basis for requiring mitigation, and the method used to calculate the mitigation required. Calculations of project impacts and the mitigation required (e.g., water capacity, road level of service analyses, or turning analyses) may be required of the applicant.

A contiguous parcel owned by the same property owner (no. 7345600685) and used as part of the development on parcel no. 7345600766 is already zoned C/LI and is not included in this request. RECEIVED EC 13 2016 Community Development Summary of the Reason for the Request As part of its long-range plans for growth of transit service in the region, Metro needs to purchase additional property for indoor mechanical training activities and construction offices. For that purpose, Metro is seeking to purchase property at 12677 E Marginal Way S (parcel no. 7345600766) and 12633 E Marginal Way S (parcel no. 7345600685) from Blue Nile Holdings, LLC (see Figure 1). 7341 60069S Parcel no. 7345600766, subject of request 00675 734560 G 5 Parcel no. 7345600685, excluded from request Figure 1: Becker Transfer properties outlined in red. Source: King County iMap. The smaller parcel is zoned Commercial Light Industrial (C/LI). The larger parcel is split -zoned; the eastern portion fronting on E Marginal Way S is zoned C/LI and the western portion is zoned Low Density Residential (LDR). The site is ideal for Metro's intended future use of the site, but the split -zoned condition creates uncertainty about how the site could be developed to meet Metro's needs. Metro is pursuing the rezone to rectify this uncertainty for immediate short-term use and potential redevelopment. Metro understands that approval of rezones is considered within the Page 1 of 15 • • Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative larger planning context and must be consistent with the vision for Tukwila, and for the surrounding neighborhoods. Metro believes that the rezone is consistent with the vision and character for this area, and that in the long term will provide opportunities for enhancement of the boundary between the residential and commercial areas. The use of the site since at least 1975 has been light industrial, specifically a truck terminal use with accessory warehouse and parking. Truck terminal use is nonconforming to the existing LDR zoning and conforming to the existing C/LI zoning (see Figure 2). Parcel no. 7345600766, subject of request r Parcel no. 7345600685, excluded from request Figure 2: Excerpt of City of Tukwila Comprehensive Plan & Zoning Map, subject properties outlined in red. Purple zoning is C/LI, yellow zoning is LDR. Split -zoning is discouraged by the City of Tukwila's Comprehensive Plan and tends to create uncertainty for future development or redevelopment. A history of the land use and zoning on the property is included in this application. Rezoning the property will strengthen the boundary between the LDR zone to the west and C/LI zone along E Marginal Way S. It will provide certainty for Metro by ensuring that the office uses can continue and that the site can be developed efficiently for those uses. To the extent that rezoning will remove confusion around applicability of zoning to the site and its nonconforming status, future redevelopment would be encouraged and that would offer opportunities to make the site development more conforming to existing regulations. Metro's Intended Use of the Site and a Conceptual Plan If the rezone is approved, Metro's current thoughts for use of the site are for office and indoor training activities that currently occur on the nearby South Base facilities. Metro has provided a drawing of what a potential layout for office and training use could look like (see Exhibit I), but is not seeking any review or approval of that layout at this time. Before Metro can realistically create a plan for specific uses that addresses applicable development standards, the rezone would need to be approved. Any future changes to the site to allow redevelopment would be subject to review by the City of Tukwila through Design Review because of the proximity to the LDR zone. At the time of a proposed redevelopment of the site, Metro would work with the City of Tukwila to ensure compliance with site development standards. Site Description The properties are collectively identified in the King County Assessor's records as "Becker Transfer." Parcel no. 7345600766 is approximately 1.64 acres (71,440 square feet) in size. Parcel no. 7345600685 is approximately 0.26 acres (11,490 square feet) in size. Parcel no. 7345600766 is split -zoned: the eastern portion fronting on E Marginal Way S is zoned Commercial/Light Industrial (C/LI), and the western portion is zoned Low Density Residential (LDR). Parcel no. 7345600685 is zoned C/LI. Refer to Figure 2. Page 2 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative The parcels are used as a single property that serves as the base of operations for Blue Nile Trucking, LLC. The site is accessed by one driveway on E Marginal Way S and two driveways on S 128th Street. Permanent structures include a service garage, distribution warehouse, loading dock, and fuel pump built in 1975; the remainder of the parcels are paved and/or graveled. Vehicles and trailers of varying sizes are stored along the north and west property lines. Surrounding land uses include a mix of single-family residential, commercial, and industrial. The east branch of Riverton Creek is present in the vicinity of and on the property. The creek flows through an open ditch and onto the northwest corner of the property for approximately 25 feet before entering an underground pipe. The creek flows through approximately 195 feet of underground pipe and daylights into another open ditch (see Exhibit G). The existing stream and buffer are significantly degraded due to undergrounding and surrounding development. Request Requests for changes in zoning are made pursuant to Chapter 18.84 TMC. Granting a rezone and accompanying Comprehensive Plan map change is allowed when consistency with the following criteria can be demonstrated: 1. The proposed amendment to the Zoning Map is consistent with the goals, objectives, and policies of the Comprehensive Plan. The proposed amendment is consistent with the applicable goals, objectives, and policies of the City's Comprehensive Plan. The proposed change from LDR to C/LI will clarify the boundary between the two zones at the subject location; facilitate future redevelopment consistent with the character of E Marginal Way S; and eliminate a nonconformity. Community Image and Identity Element The Community Image and Identity element of the Comprehensive Plan establishes a framework to celebrate the City's history and environment, build on diversity, foster civic engagement, and accommodate growth that furthers the community's vision.' The proposed rezone will contribute to this framework by improving consistency of the property's designation with the following goals and policies: • Goal 1.1— A community of inviting neighborhoods and vibrant business districts. The subject property is accessed from E Marginal Way S and S 128th Street. The parcel is situated at the boundary between commercial and industrial uses on E Marginal Way S and residential uses further west and south in the area. The property is split - zoned, leading to a lack of clarity in the use and development of the site. Rezoning the property will help create a consistent expectation about land use on the lot and will clearly define the residential neighborhood as distinct from the commercial and industrial uses along E Marginal Way S. The proposed rezone will expand the C/LI zoning boundary to be consistent with the property boundary and the current use of the property. The proposed rezone is not expected to impact the character of the residential area for several reasons. The residential neighborhood has grown up around this industrial use that has been in continual operation since at least 1975 (see response to criterion 2, below, for additional property history). Additionally, given that a portion of the property is already zoned C/LI, 1 Tukwila Comprehensive Plan, Community Image and Identity Element, page 1-2. Page 3 of 15 • • Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative the rezone will not invite new uses that are not already allowed adjacent to the residential neighborhood. Finally, the east branch of Riverton Creek, located along the west side of the subject property and approximately coincident with the proposed rezone, serves as a natural boundary or buffer between different land uses. The rezone will encourage the potential redevelopment of the site which may provide an opportunity to enhance the aesthetics of the site, clearly define the boundary to adjacent land uses, and provide capital investment into the neighborhood. • Policy 1.1.2 — Strengthen the image and character of Tukwila's distinct areas and neighborhoods. The subject property takes primary access from E Marginal Way S and is part of a node of C/LI and Neighborhood Commercial (NCC) zoning along this arterial that is one lot deep (except on the subject parcel) (see Figure 3). Rezoning the west side of the subject property to be consistent with this district will strengthen the image and character of the node by clarifying the uses allowed on the site, creating a consistent expectation about development on the property, and establishing clear definition between the residential neighborhood to the west and the commercial/light industrial uses along E Marginal Way S. Figure 3 Excerpt of City of Tukwila Comprehensive Plan & Zoning Map, subject properties outlined in red. Economic Development Element The overall goal of the Economic Development element is to enhance the economic well- being of the community, including stimulating economic improvement for individual businesses and the community. The proposed rezone is consistent with this purpose and addresses the following goals and policies: • Goal 2.1— Tukwila has a strong role as a regional business and employment center which allows it to enhance and promote the community's well-being. The proposed rezone is supportive of the continued business use of the subject property (and, as described above, is not detrimental to the residential neighborhood to the west). Page 4 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative The rezone will eliminate a confusing split -zoning condition, which will clarify how the property can be used and support future redevelopment of the site as a commercial/light industrial property similar to other uses along E Marginal Way S. This contributes to Tukwila's image as a regional business center. The proposal is consistent with policies intended to implement this goal, as described below. • Policy 2.1.16 — Promote and preserve economic use of industrial lands outside the Manufacturing Industrial Center (MIC) through appropriate buffering requirements and use restrictions. The subject property is located just south of the MIC boundary, along E Marginal Way S, and has been in continual use as a commercial/light industrial property since before the neighborhood was annexed in 1989. The proposed rezone supports this policy by preserving the existing C/LI zoning and expanding it slightly to be consistent with the existing parcel boundary and other similar properties. Additionally, the proposed rezone will eliminate a confusing split -zoning condition, ultimately clarifying how the property can be used and supporting future redevelopment of the property. The C/LI zone and the landscaping requirements in Table A of TMC 18.52.030 establish appropriate buffering requirements and use restrictions to ensure that commercial or light industrial development is compatible with nearby residential uses. Table A in the code shows the standard buffer depths of 6 feet and 0 feet for side and rear yards, respectively, are increased to 15 feet, and the intensity of buffer plantings raised from Type II to Type III for new development within 50 feet of a residential zone. Design review is required for new development within 300 feet of a residential zone. These standards are protective of residential development and ensure commercial and light industrial development is compatible with surrounding land uses while also promoting viable and attractive commercial and industrial areas. In addition, the requirement for a stream buffer also provides a natural division between the two types of uses. • Policy 2.1.17 — Include standards in the development regulations for industrial uses that adequately mitigate potential adverse impacts on surrounding properties and public facilities and services. In addition to the use and buffering requirements described above, development in the C/LI zone is subject to performance standards, including standards adopted by the Puget Sound Air Pollution Control Agency for odor, dust, smoke, and airborne pollutants; noise standards adopted in TMC Chapter 8.22; and State and Federal standards for water quality and hazardous materials. Review under the State Environmental Policy Act (SEPA) provides substantive authority to mitigate potential adverse environmental impacts. Natural Environment Element The Natural Environment element guides future development in a manner to protect the community's environment, improve quality of life within the City, and protect residents from natural hazards. The proposed rezone addresses the following goals and policies in this element: • Goal 4.1— The City's air, land, and water resources are restored and protected for future generations and Policy 4.1.5 — Develop and implement programs that encourage Tukwila residents and businesses to take active measures to protect Page 5 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative and enhance Tukwila's natural environment. Such measures could include the use of Low Impact Development (LID) techniques, natural streambank restoration, non -toxic lawn care, composting, and recycling, among others. The proposed rezone will clarify applicable use requirements and position the property for redevelopment, which presents an opportunity to implement forward -thinking development techniques such as Low Impact Development (LID) and environmental enhancement and remediation (if necessary), consistent with this goal. The City has adopted a Critical Areas Ordinance in TMC Chapter 18.45, "Environmentally Sensitive Areas." The purpose of this chapter is to protect the environment, human life, and property; identify and classify ecologically sensitive areas; and protect these areas and their functions while allowing for reasonable use of public and private property. New development on the subject parcel is required to comply with applicable critical areas requirements to minimize development impacts using best available science. The east fork of Riverton Creek flows across the northwest corner of the property through an underground pipe, and redevelopment of the property presents an opportunity to address this sensitive area. The subject property has already had some environmental remediation and cleanup related to its historic use as a trucking facility. Contamination from leaking underground storage tanks was addressed in 1999 and periodic review by the Department of Ecology confirms that the remedial actions continue to eliminate exposure to contaminated soils by ingestion and contact. Work was performed under the Model Toxics Control Act and the Voluntary Cleanup Program (codified in Chapter 173-340 WAC). A restrictive covenant is recorded on the property documenting the contamination and cleanup work and prohibiting work that could disturb contaminated soils without review and approval by the Department of Ecology. Future work on the property is required to coordinate with the Department of Ecology and address the restrictive covenant on the property. Substantial disturbance of the property could result in expanded cleanup efforts to eliminate contamination. • Goal 4.4 — Water resources that function as a healthy, integrated system; provide a long-term public benefit from enhanced environmental quality; and have the potential to reduce public infrastructure costs. The east fork of Riverton Creek flows across the northwest corner of the property primarily through an underground pipe. Approximately 25 feet of the creek flows through an open ditch before entering an underground pipe, where it travels for approximately 195 feet before daylighting into another open ditch (see Exhibit G). Redevelopment encouraged by the proposed rezone would provide opportunities to address this water resource, including improving surface water quality and quantity, restoring degraded buffer areas, and/or daylighting the stream. All of these opportunities would improve the health of water resources at and downstream of the subject stream and provide public benefits. • Goal 4.6 — Watercourses and their buffers, wetlands and wetland buffers protected from encroachment and degradation and improved through mitigation, enhancement restoration projects. The east fork of Riverton Creek has a significantly degraded buffer and is low - functioning due to being undergrounded in the property's vicinity. Redevelopment Page 6 of 15 4 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative encouraged by the proposed rezone would provide an opportunity to improve buffer and watercourse conditions. • Policies 4.6.1 through 4.6.4 — Policies related to regulation of land use and development, mitigation requirements, and sensitive areas studies. The City of Tukwila has adopted a comprehensive Critical Areas Ordinance (TMC Chapter 18.45) to regulate development in and adjacent to sensitive areas. The regulations ensure development is located and designed to achieve no net loss of sensitive areas functions through mitigation sequencing and compensatory mitigation. Redevelopment encouraged by the proposed rezone is required to comply with these regulations and provides an opportunity to improve conditions for the largely undergrounded stream. • Goal 4.7 — The water quality in Tukwila's wetlands, watercourses, fish and wildlife habitat areas and the Green/Duwamish River is improved over time. The stream has a significantly degraded buffer and is low -functioning due to being undergrounded at and in the property's vicinity. Redevelopment encouraged by the proposed rezone would provide an opportunity to improve buffer and watercourse conditions. • Policy 4.7.1— Improve surface water management and ensure provision of water quality treatment where required. Redevelopment encouraged by the proposed rezone would be required to conform to applicable stormwater and surface water management techniques and the King County Surface Water Design Manual 2016 (2016 KCSWDM) adopted by the City of Tukwila. • Goal 4.8 — Surface water generated by urban development does not exceed pre - development discharge rates The subject parcel is almost entirely covered with impervious surfaces. While the re- zone application will not modify the percentage of impervious surfaces on the site, future redevelopment encouraged by the proposed rezone will be required to comply with development standards that will reduce the amount of impervious surface coverage and detain, treat, and discharge surface water. Residential Neighborhoods Element The Residential Neighborhoods element focuses on neighborhood sustainability to preserve and enhance the sense of community in each residential neighborhood. The proposed rezone will occur adjacent to an existing single-family residential neighborhood. Because the rezone would affect land currently zoned for single-family residential use, Goal 7.1 and Policy 7.1.1 appear to be most applicable to the proposed rezone and are addressed below: • Goal 7.1— Residential Land Use Pattern: A land use pattern that encourages a strong sense of community by grouping compatible and mutually supportive uses and separating incompatible uses. The existing property is split -zoned, with the western portion zoned LDR and the eastern portion zoned C/LI. Since at least 1975, the property has been used for trucking operations, which is nonconforming to use requirements in the LDR zone. The split - zone condition creates confusion in the application of development requirements and therefore does not tend to encourage a sense of community at that location. In fact, it Page 7 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative tends to blur the boundary between the residential community and commercial operations. The proposed rezone will clarify the expectation for the use and development of the property in the future, which will solidify the character of the neighborhood in the immediate vicinity of the rezone and exclude incompatible uses. from the LDR zone. The east branch of Riverton Creek creates a natural boundary to define residential uses from the commercial and industrial uses fronting along E Marginal Way S. • Policy 7.1.1— Maintain a comprehensive land use map that supports the preservation and enhancement of single-family and stable multi -family neighborhoods; eliminates incompatible land uses; and clearly establishes applicable development requirements through recognizable boundaries. The split -zone condition is confusing and does not provide a clear and recognizable boundary between land uses. The proposed rezone will establish a recognizable boundary and eliminate a confusing split -zone condition for the subject property. It will also make the boundary of the C/LI node around the intersection of E Marginal Way S and S 128th Street consistent on this parcel by expanding the C/LI zone to the property boundary. The rezone is likely to encourage redevelopment of the site and meet applicable development regulations which are designed to enhance the buffer between commercial and residential uses. 2. The proposed amendment to the Zoning Map is consistent with the scope and purpose of TMC Title 18, "Zoning Code," and the description and purpose of the zone classification applied for. The proposed rezone is broadly consistent with the scope and purpose of Title 18 TMC, "Zoning Code." The zoning code implements the City's Comprehensive Plan and, as discussed above, the proposed rezone is consistent with numerous goals and policies therein. More specifically, the proposed rezone is consistent with the description and purpose of the C/LI zone. Pursuant to TMC 18.30.010, the C/LI district "is intended to provide for areas characterized by a mix of commercial, office, or light industrial uses. The standards are intended to promote viable and attractive commercial and industrial areas." The properties around the intersection of E Marginal Way S and S 128th Street are a mix of primarily commercial and industrial uses consistent with the purpose of the C/LI zone, including the subject property which is used as a trucking facility. The subject property is similar in character to commercially- and industrially -zoned property in the immediate vicinity (see Figure 4). Properties with frontage along E Marginal Way S tend to be zoned and used as commercial and industrial businesses. Uses transition from much more intense industrial activities with large warehouses and significant vehicular traffic in the north to lighter industrial and commercial uses further south. E Marginal Way S is a high -volume arterial with excellent connectivity to local and regional transportation networks. Along E Marginal Way S, the C/LI zoning serves as a logical transition between the Manufacturing Industrial Center (MIC) and industrial zoning (L) to the north and the neighborhood commercial zoning (NCC) to the south (see Figure 3, above). Page 8 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative • ,il A—v Figure 4: Vicinity map, subject property outlined in red. Source: King County iMap. ,--F,_, -:-'••Ap'1,,,:,' '- ri-.7'-2-0.',4 1 —I . `.i sfir 1i 74 r a. I LDR zoning is not appropriate for the subject site. The purpose of the LDR zone is "to provide low -density family residential areas together with a full range of urban infrastructure services in order to maintain stable residential neighborhoods, and to prevent intrusions by incompatible land uses." The property has been in continual operation as a trucking facility since prior to its annexation into the City of Tukwila. A trucking facility is nonconforming to the use provisions of the LDR zone. Chapter 18.70 TMC, "Nonconformity," allows legally established nonconforming uses to continue and sets forth limitations on any expansion of nonconforming uses. A lapse or change in the use would cause abandonment of rights to nonconformity and any new use established is required to comply with current use regulations. In this way, TMC Chapter 18.70 seeks to reduce nonconformity as much as possible. The proposed rezone would bring the nonconforming portion of the trucking facility (that portion located in the LDR zone) into conformance with the zoning code.

There are changed conditions since the previous zoning became effective to warrant the proposed amendment to the Zoning Map. Conditions have changed considerably since the previous zoning became effective. The proposal to rezone the western portion of parcel no. 7345600766 is reasonable and warranted by the change in circumstances. The subject properties were created in unincorporated King County as Riverton, a replat of a portion of Riverside Interurban Tracts, on June 15, 1906 (see Figure 5).2 Contemporary legal descriptions also refer to this area as "Riverton Addition." Thereafter, Lots 4 and 18-25 of Block 9 of Riverton were acquired by a single owner and a trucking operation was established on the property.' The Becker family owned the property at the time it was developed with the current service garage, distribution warehouse, loading dock, and related improvements in 1975. > /e7csd'--j'22O •'r 6J • �' \w I a. l 1 •1• i 0 ti C. i d q3 1 v /(P,.3J 13 Po7.do • IS 16 17 Is .50 19 9 ta �,¢- yfti o i a h 4f 1.

Two businesses (Becker Trucking Inc. and Becker Transfer Co.) appear to have grown from this startup. Becker Trucking Inc. has been in operation since 1925 and operates out of Tukwila. Becker Transfer Co. bills itself as a fourth - generation transportation company and operates out of Issaquah.

On March 27, 1989 the Tukwila City Council voted to approve ordinance no. 1508 to annex the Riverton Annexation Area effective April 15, 1989. A zoning map was included with this ordinance confirming the zoning classifications applied in ordinance no. 1480 for the subject property (see Figure 8).

No. 1508. Subject property is outlined in red. Lots 18-21 are zoned R-1 and lots 22-25 are zoned C-M. In 1995, the City of Tukwila began to rewrite its comprehensive plan and zoning code to conform to the recently -adopted Growth Management Act. Ordinance no. 1757 repealed ordinance no. 1479 (among others) and adopted the 1995 Comprehensive Land Use Plan and Map for the City of Tukwila. Ordinance no. 1758 repealed ordinance no. 1481 (among others) and overhauled Title 18 TMC (Zoning Code) and adopted a new zoning map. The zoning code amended the number and names of zoning districts in the city. R-1 became LDR (Low Density Residential) and C-M became C/LI (Commercial/Light Industrial). Lots 18-25 appear to have been consolidated between the Riverton annexation in 1989 and the zoning map adoption in 1995. The lot consolidation did not affect the zoning boundary, resulting in a split -zoned lot. The zoning boundary was not changed in 1995, and the property remains split -zoned today. The existing trucking operation is nonconforming to the LDR use requirements in Table 18-6, TMC 18.09, and TMC 18.10.020. Page 12 of 15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative The Becker family sold the property in 2005 to C&D Wells, LLC. C&D Wells, LLC sold the property to Blue Nile Holdings, LLC in 2016. Blue Nile Trucking, LLC continues to operate a trucking business from the property. The initial zoning districts applied in 1988-1989 do not appear to have been based on existing conditions or uses. The trucking business was in active operation on the site (having completed improvements in the mid-1970s) at the time. The character of the neighborhood has changed dramatically since zoning was initially applied and continues to evolve to this day. Industrial uses have spread southward from the Duwamish Manufacturing Industrial Center (MIC) and SR-599. As a result, residential development has occurred generally further to the south of the site. E Marginal Way S has become increasingly used for freight and other large vehicles. The evolution of neighborhood character is a changed condition warranting an amendment to the zoning map. The amendment will also eliminate a split -zone condition, bring a legally -established nonconforming use into conformance with the TMC, and establish zoning more consistent with the conditions along E Marginal Way S. 4. The proposed amendment to the Zoning Map will be in the interest of furtherance of the public health, safety, comfort, convenience, and general welfare, and will not adversely affect the surrounding neighborhood, nor be injurious to other properties in the vicinity in which the subject property is located. The request would extend the Commercial/Light Industrial (C/LI) boundary from the approximate center of a parcel to include the full boundaries of the parcel. The C/LI zone allows a number of commercial and light industrial uses that are consistent with the character of E Marginal Way S and nearby industrial uses. Impacts to neighboring residential properties are not anticipated. The residential neighborhood has grown up around the existing commercial/industrial business and the eastern portion of the property is already zoned C/LI. The rezone will not invite new uses that are not already allowed adjacent to the residential area. Development requirements set forth in TMC Chapter 18.30, "Commercial/Light Industrial (C/LI) District," establish appropriate buffers, increase setbacks compared to those required under the LDR zone, require landscaping screening to separate the C/LI uses from residential development, and require a stream buffer from the east branch of Riverton Creek. See Table 1, below, for a comparison of C/LI and LDR dimensional standards. In addition to dimensional requirements, new developments must demonstrate adherence to performance standards, including standards adopted by the Puget Sound Air Pollution Control Agency for odor, dust, smoke, and airborne pollutants; nose standards adopted in in Chapter 8.22 TMC; and State and Federal standards for water quality and hazardous materials. Review under the State Environmental Policy Act (SEPA) provides substantive authority to mitigate potential adverse environmental impacts for future development. Design review is required for any new development within 300 feet of a residential zoning district, which would apply to the subject property. Design review is intended to create well - designed developments that are harmonious with the natural and manmade environments. Review criteria for C/LI developments are related to the following topics: • Relationship of structure to site; • Relationship of structure and site to adjoining area; • Landscaping and site treatment; Page 13of15 Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative • Building design; and • Miscellaneous structures and street furniture. Chapter 18.60 TMC sets forth design review criteria that will protect the residential neighborhood. Design review is completed either administratively by the Director of Community Development or quasi judicially by the Board of Architectural Review. Design review can include conditions of approval to address any potential issues that arise during review. Table 1: Comparison of C/LI and LDR dimensional requirements.

A restrictive covenant has been recorded on the property to limit activities on the site to protect the environment and the public health, safety, and welfare. Conclusion The request, if approved, will rezone the western portion of parcel no. 7345600766 from Low Density Residential (LDR) to Commercial/Light Industrial (C/LI), thus removing the split -zone condition and recognizing the use that has occupied the site since at least the 1970s. Metro is seeking the rezone to facilitate its use of the property. The responses to the decision criteria set forth in TMC 18.84.020 consider the rezone within the larger context of the City's plan for this area, including the full scope of allowable uses within the C/LI zone. The same range of uses is currently allowed on the east portion of the subject property and, with buffers, setbacks, and landscaping requirements, redevelopment to a conforming use would offer opportunities to address site conditions or potential impacts and result in a net benefit to the neighborhood. • The proposal is consistent with the Tukwila Comprehensive Plan, including goals in the Community Image and Identity, Economic Development, Natural Environment, and Residential Neighborhoods elements. The proposal protects existing commercial/light industrial land and positions it for future redevelopment. Redevelopment of the property will occur in conformance with development and environmental regulations, and presents Page 14 of 15 • Rezone West Portion of Parcel No. 7345600766 from LDR to C/LI Exhibit F: Project and Decision Criteria Narrative significant opportunities to protect, enhance, or restore natural features. The rezone will eliminate a split -zone condition and create a clearly defined boundary between residential and non-residential uses. • The proposal is consistent with Title 18 TMC in general and the purpose and intent of the C/LI zone set forth in Chapter 18.30 TMC. The property is in an area characterized by a mix of commercial and light industrial uses and fronts along E Marginal Way S, a busy arterial. • Conditions have changed since zoning was applied in 1988-1989 and updated in 1995. The character of the neighborhood has changed dramatically: industrial uses have expanded to the north, especially with the establishment of the Duwamish Manufacturing Industrial Center (MIC). Residential development has occurred to the south and west, migrating away from the MIC. E Marginal Way S has become increasingly used for freight and other large vehicles. • The proposal is protective of the public health, safety, and welfare and will not adversely affect the surrounding neighborhood. Basic development standards, performance standards, and critical areas requirements mitigate potential adverse impacts to the residential neighborhood. Design review is required when new development occurs within 300 feet of a residential zone, which will ensure the use and site design is fully compatible with existing residential neighborhoods. Metro believes that this application demonstrates that a rezone is consistent with and satisfies the approval criteria in TMC 18.84.020. Metro therefore respectfully requests approval of the rezone request.

(Otak) to identify and characterize critical areas at 12677 E Marginal Way S (Parcels #7345600766 and #73456100685) to support the potential acquisition of the properties. Metro Transit is also planning to submit a rezoning request to the City of Tukwila for parcel #7345600766. This technical memorandum presents the findings of the reconnaissance level critical areas study and Tukwila Municipal Code (TMC) review. The environmental impacts of the proposed rezoning are also assessed to support the State Environmental Policy Act (SEPA) compliance process for the non -project action by the City of Tukwila. Critical areas reviewed for this memorandum include wetlands, watercourses, and fish and wildlife habitat conservation areas (FWHCAs) as regulated by TMC Chapter 18.45 (Environmentally Sensitive Areas). The two parcels, herein referred to as the project site, are located at the corner of S 128th Street and E Marginal Way in the City of Tukwila, King County, Washington (Figure 1 — Vicinity Map). Otak biologists completed a field survey to identify and characterize critical areas and their buffers on the project site on November 29, 2018. Site photographs and figures are included with this memorandum. Methods Methods to complete the reconnaissance level critical areas assessment included reviewing published environmental documentation and completing a field visit to investigate the presence and extent of watercourses, wetlands, FWHCAs, and associated buffers on site. The presence of wetlands was investigated using the three -parameter approach detailed in the Corps of Engineers Wetlands Delineation Manual (USACE 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (USACE 2010). Wetland boundaries were estimated for the purpose of the reconnaissance -level field survey. Wetland habitats were classified according to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin, et al. 1979), and the hydrogeomorphic (HGM) wetland classification as adopted by Hruby (2004). Wetland functions were rated using the 2004 Washington State Wetland Rating System for Western Washington (Hruby 2004), and preliminary wetland buffer widths were determined by wetland rating per TMC 18.45.080 (Wetlands Designations, Ratings and Buffers). k:lproject1328001328701projectdocs132870b bluenile criticalareaslca memoltechnical memorandum_2018-1210.docx RECEIVED DEC 13 2018 2731 Wetmore Avenue, Suite 300 Everett, WA 98201 • Phone (425)493-5221 otak.com Community Development Page 2 Critical Areas Assessment and Proposed Rezoning Review December 10, 2018 Watercourses were identified based on indicators of flowing water and an ordinary high-water mark (OHWM), and classified according to TMC 18.45.100 (Watercourses Designations, Ratings and Buffers). Identification of OHWM was based on the evaluation of stream physical characteristics, such as: the natural line impressed on the bank, change in sediment and vegetation characteristics, wracking, erosion/scour, and silt deposits. The presence of FWHCAs in or near the project site was assessed by visual observation during the field visit in combination with reviewing available published information. Background Review Background information reviewed prior to completing the site investigation included the following resources: • City of Tukwila Comprehensive Plan & Zoning Map (City of Tukwila 2015) • City of Tukwila Sensitive Areas Map (City of Tukwila 2015a) • King County iMap (King County 2018) • U.S. Fish and Wildlife (USFWS) —National Wetland Inventory (NWI) (USFWS 2018) • Washington Department of Natural Resources (DNR) — Forest Practices Application Mapping Tool (WDNR 2018) • WDFW — Priority Habitats and Species (PHS) on the Web (WDFW 2018) • Washington Department of Fish and Wildlife (WDFW) — SalmonScape (WDFW 2018a) The City of Tukwila Sensitive Areas Map (attached) identifies one Type 2 stream within the project site, herein referred to as the east branch of Riverton Creek. The east branch of Riverton Creek is mapped as an open channel west and north of the project site boundaries and piped on site. The stream is piped downstream of the project site along E Marginal Way S from approximately S 126'h Street to State Route (SR) 599. Type 2 streams are defined as Type F (fish) watercourses per TMC 18.45.100 and have a 100-foot-wide buffer. 100-foot-wide stream buffers are shown extending from the open portions of the stream channel onto the project site. No other wetlands or watercourses are mapped on or near the project site by King County, USFWS, WDNR or WDFW. WDNR and WDFW map the east branch of Riverton Creek up to SR 599 north of S 120th Place, but no watercourse is shown south of that intersection. WDNR types the east branch of Riverton Creek as a Type N (non -fish) watercourse. The west branch of Riverton Creek is shown flowing parallel to SR 99 approximately 1,000 feet west of the project site. The west branch of Riverton Creek is Type F (fish) per WDNR and a Type 2 watercourse per the City of Tukwila's Sensitive Areas Map. Per the City's Sensitive Areas Map, no FWHCAs are mapped on or within the vicinity of the project site. No areas of geologic instability or abandoned coal mines, two additional types of regulated environmentally sensitive areas, are mapped on the project site as well. Findings Site Description The project site is located within amongst residential and commercial properties. Single-family residential neighborhoods are generally located west of the project site, and commercial properties are located to the north and south along E Marginal Way S. The two parcels combined are approximately 1.85 acres in size and currently used to store small motor vehicles and semi -truck trailers in a partially paved storage yard operated by the Blue Nile Trucking. Commercial buildings are in the southeast corner. The western and northern edges of the project site are bordered by coniferous trees with herbaceous plants in the understory and a chain -link fence. Patches of invasive, non-native Himalayan blackberry (Rubus armeniacus) are also located along the fence lines. In general, k:Iproject132800132870Iprojectdocs132870b bluenile_criticalareaslca memoltechnical memorandum_2018-1210.docx Page 3 Critical Areas Assessment and Proposed Rezoning Review December 10, 2018 the western half of the storage yard is gravel and the eastern half is paved. A catch basin is present within the gravel lot in the northwest corner of Parcel #7345600766 that provides access to a piped stream underground. Watercourses The east branch of Riverton Creek was identified on the project site. The stream emanates from a culvert immediately west of the chain -link fence bordering the western edge of parcel #7345600766. The stream has an approximately 7-foot wide bank full width and flows for approximately 25 feet through a rock -lined channel before entering a 36-inch corrugated metal pipe culvert at the edge of the gravel storage yard. Concrete chunks and other debris was observed in the channel. The stream is piped approximately 135 feet to the northeast beneath the gravel lot and turns north for approximately 60 feet before discharging at the northern edge of the property into an open channel. The east branch of Riverton Creek is a Type 2 (fish) watercourse per TMC 18.45.100 (Watercourse Designations, Ratings, and Buffers). Open, Type 2 watercourses have a standard 100-foot-wide buffer per TMC 18.45.100.C. The TMC does not state explicitly whether piped portions of streams have standard buffers or not, but the piped stream on site does not appear to have a standard buffer width per the City's Sensitive Areas Map. All commercial and industrial buildings are required to have a 15-foot set -back and all other development shall have a 10-foot set -back from the buffer's edge. Buffer conditions are degraded and low functioning due to the existing gravel and paved lot and minimal vegetation cover. The stream buffer overlaps the gravel lot as shown on Figure 2 (Critical Areas). Per DNR's typing methodology, watercourses with perennial flows that have defined channel two feet or greater within the bank full width and have a gradient of 16 percent or less are considered Type F streams unless the stream has been proven not to contain fish using methods described in Forest Practices Board Manual Section 13. Due to the perennially flowing water, channel characteristics, and approximate three percent grade downstream of 37th Avenue South and through the project site, the east branch of Riverton Creek is classified a Type 2 (Fish) watercourse. Wetlands Two riverine wetlands (Wetlands A and B) were identified off -site along the east branch of Riverton Creek. Estimated wetland boundaries are shown on Figure 2 (Critical Areas). Wetland A is located north of the subject property between the northern property edge and S 126th Street and is situated between residential and commercial land uses. Wetland A is classified as palustrine forested habitat under the Cowardin classification system, and as riverine under the HGM system as adopted by Hruby (2004). Dominant vegetation in Wetland A includes black cottonwood (Populus balsamifera spp. trichocarpa), Pacific willow (Salix lucida), Sitka willow (Salix sitchensis), salmonberry (Rubus spectabilis), and creeping buttercup (Ranunculus repens). Wetland B is located west of the subject property within the back yard of the abutting residential property. Wetland B is classified as palustrine emergent habitat under the Coward classification system, and as riverine under the HGM system as adopted by Hruby (2004). Dominant vegetation in Wetland B includes broadleaved cattail (Typha latifolia) and creeping buttercup. Wetlands A and B were preliminarily classified as Category III wetlands. Both wetlands have a standard buffer width of 80 feet per TMC 18.45.080.D. Wetland buffers on the subject property are superseded by the 100-foot- wide stream buffer as shown on Figure 2 (Critical Areas). k:lproject1328001328701projectdocs132870b bluenile criticalareaslca memoltechnical memorandum_2018-1210.docx Page 4 Critical Areas Assessment and Proposed Rezoning Review December 10, 2018 Proposed Zoning Changes and Code Review The following section includes an assessment of the potential environmental impacts of the proposed rezoning relative to TMC Chapter 18.45 (Environmentally Sensitive Areas). This assessment is intended to support the SEPA compliance process for the proposed rezoning. An Endangered Species Act Screening Checklist is also enclosed with this memorandum and is expected to accompany the non -project action SEPA checklist for the proposed rezoning. Proposed Rezoning Parcel #7345600685 and the eastern half of Parcel #7345600766 is zoned Commercial Light Industrial (CLI). The western half of parcel #7345600766 is zoned Low Density Residential (Figure 3 — Existing Zoning). Metro Transit proposes to re -zone Parcel #7345600766 entirely as CLI for consistency with the existing and proposed future land use. Environmental Impacts and Redevelopment Opportunities Redevelopment with either residential or commercial/light industrial uses could create substantial opportunities for environmental improvements and enhancements of ecological functions that are currently degraded. The project site is currently used for commercial/light industrial purposes, and re -zoning the western portion of parcel #7345600766 would have no noticeable effects to the existing low functioning watercourse and wetland/stream buffers on site or adjacent to this area due to the existing legal, non -conforming use. Under new development proposals, existing legal and nonconforming land uses within the current wetland/stream buffer areas could be removed, and new developments would be required to conform to the provisions of TMC Chapter 18.45 (Environmentally Sensitive Areas) that limit or do not allow development within critical areas or critical area buffers. For example, standard watercourse buffers may be reduced only where the buffer is significantly degraded due to existing development within the prescribed buffer, provided that the existing buffer is enhanced in accordance with an approved buffer enhancement plan (TMC 18.45.100.E). The standard buffer width cannot be reduced by more than 50 percent under any land use proposal. Per TMC 18.45.100.E, any buffer reduction proposal must demonstrate that it will not result in direct, indirect or long-term adverse impacts to watercourses, and that an on - site buffer enhancement plan is prepared. Due to the currently degraded buffer conditions on site, a buffer reduction request would likely be justified and approved under any future development proposal. Allowed development or other activities within critical areas and critical area buffers —and any potential exemptions for such alterations —would pertain to both LDR and CLI zoned lands. The City of Tukwila's environmentally sensitive areas code will pertain to all zoning areas and does not differ between LDR and CLI land uses. Redevelopment may provide opportunities for mitigation and/or wetland and stream buffer enhancement in the disturbed buffer areas using best available science, with an anticipated improvement of ecological functions provided by the critical area and its buffer. Any proposed development plan within watercourse buffers would need to include a buffer mitigation plan per TMC 18.45.110 (Watercourse Alterations and Mitigation) and buffers would need to be restored to an enhanced state (TMC 18.45.110.D.2). Because all land uses and proposed development must comply with the City of Tukwila's environmentally sensitive areas code, significant impacts to environmentally sensitive areas and their buffers are not expected to result from the proposed zoning change. kAproject1328001328701projectdocs132870b bluenile criticalareaslca memoltechnical memorandum 2018-1210.docx Page 5 Critical Areas Assessment and Proposed Rezoning Review December 10, 2018 References City of Tukwila (City). 2015.

It is a quasi-judicial decision made by the City Council who will decide your request using the criteria listed below. It is essential that you describe in a clear and precise manner why the change should be approved. You may submit other documentation in support of your proposal. Provide a written response that demonstrates how each of the following circumstances justifies a map change for your property: 1. The proposed amendment to the [Comprehensive Plan and ] Zoning map is consistent with the goals, objectives, and policies of the Comprehensive Plan; 2. The proposed amendment to the [Comprehensive Plan and ] Zoning map is consistent with the scope and purpose of the TMC Title 18, Zoning Code, and the description and purpose of the zone classification applied for; 3. There are changed conditions since the previous zoning became effective to warrant the proposed amendment to the [Comprehensive Plan and ] Zoning Map; and 4. The proposed amendment to the [Comprehensive Plan and] Zoning map will be in the interest of and furtherance of the public health, safety, comfort, convenience, and general welfare; and will not adversely affect the surrounding neighborhood; nor be injurious to other properties in the vicinity in which the subject property is located.
