Page 2, #8: On October 25, 1988, a mitigated DNS was issued on this site for a similar office building project (88- 3 -SMP) and again in 1990 (90- 6 -SMP). Design Review (90- 12 -DR) and SEPA (EPIC23 -90) have also been issued for this development. Page 3, #11: The proposal is to development a 40,379 square foot, Class A office building on two (2) of a total 5.57 acres, as Phase Three (3) of the Fort Dent Office Park project. SEPA Amendment - EPIC 23 -90 Fort Dent Three Office Park July 31, 1997 Summary of Primary Impacts: Earth d. There is no surface indications or history of unstable soils, however, Fort Dent Two was built on piles. Fort Dent Three will have conventional concrete spread footings. g. About 71% of the site will be covered with impervious surfaces after project construction. h. Proposed erosion control measures will include filter fabric fences, interceptor swales, check dams, catch basin protection, and rocked construction. Air None Water a. Surface 2. A portion of the building, parking lot, and landscaping, along the north and east sides of the property will be constructed within 200 feet of the Green River. Work in this area will include extensions of the water, sanitary sewer, and storm drainage systems. 3. Existing is fill from the development of Fort Dent Two, and last Fall 1996, rainstorms caused some dredging and filling to support pockets of unstable soil. c. Water Runoff 1. Storm runoff will be directed to grass lined swales leading to an underground pipe, connected to an existing piped storm system to the south. Runoff will eventually outlet to the river. Plants d. An improved landscape plan is proposed, including Redtwig Dogwood, White Rockrose, Warminster Broom, Escallonia, Forsythia, Spirea and Viburnum shrubs. Tree species will include Norway Maple, Katsura, Pine, Flowering Cherry, and Flowering Pear. fie SO SEPA Amendment - EPIC 23 -90 Fort Dent Three Office Park July 31, 1997 Animals None Energy/Natural Resources None Environmental Health None Land /Shoreline Uses a. The site is currently vacant land. The green River and Fort Dent Park lie to the north and west of the proposed site. The Fort Dent Two office building lies to the south. Homewood Suites Hotel is to the southeast, and State Farm Insurance Company has an office building to the south. b. The property was once used for vegetable farming, more than 30 years ago. e. The current zoning classification of the site is Regional Commercial Mixed Use (RCMU). 1. The property will be developed in accordance with City of Tukwila Regional Commercial Mixed Use zoning regulations. Housing None Aesthetics a. The tallest point of the proposed office building would be 33 feet, or 27 feet exclusive of the HVAC unit and screening. Principal building materials will be painted drivet or tilt -up concrete, reflective glass, vision glass, and blue colored accents on the metal panels. c. Measures to reduce or control aesthetic impacts were addressed and approved by the Board of Architectural Review at the November 1990 public hearing (90- 12 -DR). SEPX Pmendment - EPIC 23 -90 Fort Dent Three Office Park July 31, 1997 Light /Glare The project site will be illuminated, as needed, with low glare lights on 10 to 20 foot standards. Ground mounted up lighting Recreation a. Fort Dent Park is adjacent to the office development. The Green River recreational trail has also been recently developed adjacent to the site. c. Benches and enhanced landscaping will be added along the Green River recreational trail. Historic /Cultural Preservation None Transportation a. Interurban Avenue South and Fort Dent Way serve the subject property. Access to these streets is from a 20 foot ingress /egress easement on the southerly property line, shared by Fort Dent Two, Homewood Suites Hotel, and eventually by Fort Dent Three. c. 142 parking stalls are proposed for Fort Dent Three. There will be additional parking available at Fort Dent Two. No stalls will be eliminated. f. The development of Fort Dent Three would generate an additional 707 vehicular trips per day on the site. Public Services None Utilities A water extension will be looped around the building, and a new sewer lateral will be constructed. Sanitary sewer and water are provided by the City of Tukwila. Electrical service is by Puget Sound Energy and telephone is by US West. Extensions of the existing services will be constructed to the new building.

In November 1990, a design review proposal for Fort Dent Three (90- 12 -DR) was approved by the Board of Architectural Review with the condition that access and amenities from the building to the shoreline be provided. A Mitigated Determination of Non - Significance (MDNS) (EPIC- 23 -90) was also approved at this time. The proposed development meets current minimum requirements of the Regional Commercial Mixed -Use (RCMU) zoning district. See Applicant's Cover Letter, dated December 20, 1996 confirming minimal changes to building modifications in current shoreline permit application. A Trail Easement Agreement runs with the land adjacent to the river that holds the City responsible for maintaining the trail, from the edge of the private property to the water. Shoreline Substantial Development Permit (18.44.80) Any substantial development within 200 feet of any shoreline must receive a shoreline substantial development permit prior to issuance of any local permits by the City. The proposed Fort Dent Three Office Park is located adjacent to the Green River. A landscape plan, required under 18.44.080, is attached to show specific measures taken to meet shoreline regulations for the river environment (18.44.130). Criteria to meet both general and specific shoreline regulations follow. General Shoreline Regulations (18.44.110) 1. The use Ls in conformance with the underlying district The proposed office park meets basic development standards of the Regional Commercial Mixed -Use (RCMU) zoning district. The project complies with the following items of municipal and county shoreline policies and regulations: Tukwila Comprehensive Plan Shoreline Design Policies: A -1. The development minimizes impacts on wildlife and significant vegetation, sandbars, wetlands, watercourses, and other important habitat features are maintained through the proper location, construction, and management of shoreline uses; A -2. The development protects riverbank vegetation and, where feasible, restores degraded riverbanks A -4. Streets, flood control, surface water drainage and sewer system projects, clearing /grading activities and landscaping are designed, located, and managed in a Staff Report to the Director , Department of Community Development L96 -0084 Shoreline Permit Fort Dent Three manner that minimizes water pollution, provides erosion control, and protects water quality A -5. The proposed development does not appear to cause significant adverse impacts on flooding, erosion, and natural resources in determining and considering the visual impact a commercial/industrial development will have on the surrounding area, within and outside of Tukwila's jurisdiction. A -6. Capital improvement projects and private development are designed, located, and managed in a manner which does not endanger public health, safety, welfare, or capacity of river to provide long -term community benefits. A -7. The development is designed and located to minimize impacts to habitat, vegetation, access, recreation, historical resources and flood control A -12. The development reflects high quality site planning, architecture, and landscaping; and includes setbacks, buffers, height/bulk provisions for open space A -13. Areas included in the Green River Plan: The development provides public access or a private natural area in lieu of physical public access. A16 -a. Access is designed and located approximately in relation to the particular site conditions and private property concerns A16 -b. Access is designed to be safe and convenient, and includes amenities such as benches, drinking fountains, and parking lighting A -17. Where appropriate, the commercial development provides a connection between concentrations of commercial activity and the trail network Tukwila Shoreline Master Program: A -2. Locate commercial/industrial development in areas with low potential for recreation or other public use. A -3. Preferences should be given to commercial and industrial development that will provide an opportunity for a substantial number of people to enjoy the shoreline. A -4. Determine and consider the visual impact that the commercial/industrial development will have on the surrounding area A -5. Encourage provisions for public access, especially visual and pedestrian, as an integral part of commercial/industrial waterfront development B1 -b. For non -water dependent economic activities, where permitted, the entire water's edge should be available for public access, consistent with private property rights. B -3. A trail system should be developed along the river. Trails should be developed for linear access through public shoreline areas; access points to and along the river should be linked by a system of trails; The connection of other trails in the region to the shoreline trail system should be encouraged and developed. To assist in developing a trail system, incentives should be offered to property owners for utilizing set back requirements C -2. Parking facilities should be located upland with provisions for adding pedestrian access to the shoreline. D -2. recreational uses should be incorporated with other shoreline activities. F -1. Determine and consider the visual impact a commercial/industrial development will have on the surrounding area F -2. Develop regulations requiring the maintenance of a buffer of permanent vegetation between developed areas and associated water bodies to improve the aesthetic qualities of the river, retard surface runoff, maintain constant water temperature, and reduce filtration. F -3. Promote linear shoreline access, especially pedestrian and non - motorized types, in the areas close to population centers. Such areas would also serve as buffers between water and developed areas. 4 Staff Report to the Director , Department of Community Development r 3 L96 O 84 Shoreline Permit Fort Dent Three F -4. Develop regulations for site coverage, building height, setbacks, and density to insure visual access to water, promote interesting development, and prevent encroachment over water. F -8. Outfalls and surface run -offs should be controlled to minimize adverse effects on the river A Trail Easement Agreement runs with the land adjacent to the river that holds the City responsible for maintaining the trail, from the edge of the private property to the water. In coordination with the Department of Parks and Recreation, the property owner is responsible for providing appropriate maintenance and safety measures in the buffer zone. 3. No structures or accessory facilities shall be located over the river unless such structures protects or promotes the public interest. Accessory facilities, such as picnic tables and benches will be located in the shoreline management environment to promote public interest in the use of the riverfront as a recreational amenity. These amenities will become part of the Green River recreational trail proposed by the City that will extend to Fort Dent Park, located immediately to the north of the proposed office development. 4. There shall be no disruption of existing trees or vegetation within the river environment unless necessary for public safety or flood control, or if allowed as part of an approved shoreline substantial development permit. The site currently contains mostly grass vegetation, blackberry bushes, and some trees. Trees, shrubs, and grass will be added between the parking lot and trail, including Washington Thorn, Kousa Dogwood, London Plane, Sweet Gum, Rhododendron, New Zealand Flax, Otto - Luyken Laurel, Snow Lady, and White Flowering Potentilla. 5. No effluent shall be discharged into the Green River which exceeds the water quality classification as established by the State for the adjacent portion of the river. Surface storm water will be channeled and collected through an approved bioswale and conveyance swale to the storm system, already in place at Fort Dent II. The system at Fort Dent II is connected to the conveyance system in Southcenter Boulevard, via Fort Dent I, before reaching the Green River. Possible runoff from parking lot areas will be channeled through the biofiltration swales. 6. All States and federal water quality regulations shall be strictly complied with Appropriate measures will be taken to comply with all state and federal water quality regulations. 7. Wildlife habitat in and along the river shall be protected The Green River serves as a mitigation route for salmon and possibly for trout. In addition, crow, finches, sparrows, robins, and duck have been observed on or near the site. No special measures have been proposed to protect this habitat from development in the shoreline management environment or in the vicinity of the proposed office building. Staff Report to the Director , Department of Community Development q1•0 3 L96-698t Shoreline Permit Fort Dent Three 8. All perimeters of landfills and other land forms susceptible to erosion shall be provided with vegetation, retaining walls, or other satisfactory mechanism for erosion prevention. In 1991, the riverbank was widened and re- vegetated with the development of Fort Dent II as an erosion control measure. No new riverbank widening is predicted by the applicant to be necessary with the development of Fort Dent III. 9. All necessary permits shall be obtained from federal, State, County or municipal agencies. A SEPA was approved as a Mitigated DNS in November 1990; Tukwila Design Review was approved in November 1990 with conditions to provide access and amenities from the building to the shoreline; A Tukwila Flood Control Zone Permit and a Tukwila Storm Drainage Permit were submitted on December 23, 1996. A Land Altering Permit may be necessary. 10. Dredging for purposes other than for navigational improvements or flood control is prohibited. All dredging occurred as part of the river widening in 1991. Approximately 1,150 cubic yards of material were removed at the time to create a slope and bench intended to allow additional flow capacity in the river. No additional materials will be removed. 11. Mining is prohibited along the river shoreline No mining will occur on the site nor along the river shoreline 12. Solid waste disposal is prohibited along the shoreline No solid waste disposal will occur along the shoreline 13. No property will be acquired for public use without dedication by or just compensation to the owner Two separate portions of land adjacent to the trail were dedicated for public use in the original proposal, approved by the Board of Architectural Review in November 1990. 14. Landfilling is prohibited within the river channel, unless such landfill is determined by the Planning Commission to protect or promote the public interest. No new landfill will occur within the river channel. 15. Notwithstanding any provisions of the Code to the contrary, removal of any cottonwood tree within the river environment, or the low impact environment, which tree is 12 inches or greater in diameter as measured 4.5 feet above grade, shall be subject to the requirements of TMC Chapter 18.54, Tree Regulations. The site is currently spotted with grass, shrubs, and trees. Specific Shoreline Regulations - River Environment (18.44.130) 1. The river environment shall consist of a 40 foot wide management zone as measured on a horizontal plane from the mean high water mark, and shall contain no uses or structures other than the following: a. public and/or private footpaths or trails b. recreational facilities such as benches, tables, viewpoints, and picnic shelters provided no such facility exceeds 15 feet in height 6 Staff Report to the Director , Department of Community Development �. 97.e' 3 L96-43084-Shoreline Permit Fort Dent Three c. support facilities for pollution control such as runoff ponds and filter systems provided they are at or below grade d. information and directional signs e. diking or bank stabilization, erosion control, and flood control purposes f. bridges g. fire lanes and dike maintenance roads h. plaza connectors between buildings and dikes not to exceed the height of the dike are permitted for the purpose of providing and enhancing pedestrian access along the river, and for landscaping purposes Strong pedestrian ties between the river side entry from the building to the river trail will be created. A picnic table, benches, and seating in the immediate area of the trail connection, as well as along the length of the river trail, will be introduced. An enhanced landscape plan was approved by the Board of Architectural Review on November 7, 1990. A copy of the landscape plan is attached. See item 2c for further detail on planting. 2. River environment uses shall conform to the following standards: a. access roads, parking or storage areas, the closest edge of which shall be a minimum of 40 feet froin the mean high water mark Parking, storage, and access roads are outside the 40 foot river environment management area. Their distance from range from the mean high water mark of the Green River range from 50 to 70 feet. b. the centerline of railroad lead tracks shall be located no closer than 40 feet from the mean high water mark, except where the railroad lead track is bridging the river N/A c. where the riverbank has been reconstructed, it shall be landscaped with suitable plant material consistent with the flood control measures to include large hardy shade and fruit trees, at maximum 30 feet on center such as maple, alder, poplar, cottonwood, sycamore, willow, oak, beech, walnut, ash and birch, or other species approved by the Director. In addition, at least one of the following landscape materials shall be used: 1. live groundcover at a maximum of 18 inches on center 2. natural grasses 3. addition to the existing natural vegetation where appropriate In 1991, the riverbank was revegetated with blackberry bushes and trees for the river widening project. In addition, vegetation along the river will be augmented with the following plant materials: 12 Tupelo, 24 Redtwig Dogwood, 12 Spirea, 16 Warminster Broom, and 23 Rosa Rugosa. All proposed plant material will have canopy less than 30 feet. Sod is proposed as groundcover (See attached geotechnical report). d. Facilities such as pumps, pipes, etc. shall be suitably screened with hardy plant material No above ground storm detention has been proposed. e. Utility easements where necessary shall be landscaped with live groundcover or natural grass cover. See Item C of this section 7 g7eic"oh Staff Report to the L9620084 Shoreline Permit Director , Department of Community Development Fort Dent Three Conclusion 1. The impact of glare on habitat in the river environment may be caused by on -site illumination. 2. There is no access easement to the Green River dike for King County flood control inspection and maintenance. 3. The location and design of information and directional signs have not been specified. 4. The maximum width of the commercial driveways proposed exceeds 35 feet. Staff recommends approval of the Type II Shoreline Development Permit for the Fort Dent Three Office Park and associated amenities in the adjacent river environment. Conditions of the decision are attached to this permit. 8 Earth Consultants Inc. Ck, IecImica] linfiitnrrs.

Geotechnical Engineering Study E- 3007 -2, November 2, 1987 Geotechnical Engineering Study Update E- 3007 -7, December 20, 1997 Dear Ms. Berlow: In accordance with the request of Rebecca Davidson, with the John C. Radovich Development Company, we have reviewed the available subsurface information in the vicinity of,the site and made site visits to observe the existing condition of the bank of the Green River for the purpose of addressing the stability of the riverbank. The condition of the riverbank was observed from both sides of the river. The majority of the riverbank is currently covered with thick vegetation consisting of grass, brush, blackberries and some trees. Soil was exposed on the bank within a few feet of the waterline on June 24, 1997. The bank appears to have an overall slope ratio of about 1.5H:1 V (Horizontal:Vertical). No indications of active erosion were observed on the riverbank. The bank was observed to slope in a uniform manner to the water line. • F-3.

Review of the plans and specifications for this project indicates that the riverbank in the area where this work was performed did not have a uniform slope parallel to the river flow and, therefore, required stabilization procedures. However, the conditions that warranted the stabilization performed by the City of Tukwila do not exist on the remaining portions of the riverbank that border the Fort Dent 3 project. The portion of the riverbank that was not stabilized by the city in 1995 was observed to be in a similar condition to the portion that was stabilized, indicating it is in a stable condition. Based ` on the observed condition of the riverbank, and the fact that earthwork construction for the Fort Dent 3 project will not occur on or immediately adjacent to the top of the riverbank, it is our opinion that the riverbank is stable in its present condition and configuration and that stabilization measures are not necessary to achieve 'a stable riverbank for the life of the project. We appreciate the opportunity to be of service on this project. Should you have any questions or need additional information, please contact us.

Earnst, P.E. Director MEMORANDUM TO: Jack Pace, Senior Planner FROM: Ron Cameron, City Engineer DATE: October 17, 1990 SUBJECT: Fort Dent Traffic Mitigations This memorandum explains the process used to determine Homewood's traffic mitigations and applies the same process to Fort Dent. The considerations are the existing LOS "F ", fairshare of the Southcenter project to correct would be "unfair ", and a compromise that provides for improving safety and capacity in inappropriate fair share approach. Peak hour trips are calculated as 13.6% of the 708 daily trips and that is 147 peak hour trips. This is from the Fort Dent Traffic Study. Previously, the Homewood Suites traffic impacts were evaluated and mitigation agreement made. That agreement of $50,000 was based on a $1,000 trip fee. There were several considerations in reaching this agreement. 1. The Homewood proposed mitigations of signal improvements were already being provided by WSDOT. 2. The City's project to increase capacity for the immediate intersections is estimated to cost over $11,000,000 which is significantly more than a "normal" intersection capacity improvement cost. 3. The immediate Interurban intersections with Grady Way and Southcenter Boulevard are at LOS "F" and capacity improvements to work with the existing network and future network should be evaluated. 4. The proportionate share of the $11,000,000 improvement for Homewood would have been $110,000 which is disproportionate in relation to other development mitigation costs. Therefore, considering other mitigation costs of the immediate area, King County and Bellevue's fees of $1,000 a trip, and the severe existing LOS "F" problem, a fairshare cost of a study to determine "immediate" capacity improvements was agreed to. Jack Pace MEMORANDUM October 17, 1990 Page 2 5. The "immediate" improvements are envisioned as widening the Interurban Avenue bridge to provide dual left turn lanes that will serve "immediate" LOS needs and work with the future improvement AND sidewalks for pedestrian safety. Both LOS and pedestrian safety will be affected by increased Homewood vehicle and pedestrian traffic. 6. Fort Dent is essentially in the same position as Homewood; 1. vehicle and pedestrian traffic will further degrade safety and capacity; 2. the major City project is still several years away and significant cost; 3. a fair share for the widening of Interurban bridge should be commiserate with other mitigation costs - i.e., not exceeding the costs determined by Bellevue, King County, and being paid in Tukwila for traffic improvements. 7. The costs for Fort Dent's 147 trips (about 3 times the 50 of Homewood) would be $147,000. 8. That mitigation would be used for the evaluation of widening Interurban bridge and approaches for dual lefts and pedestrians. If the study and work is not underway within 5 years, the funds could be used for the Southcenter Boulevard project. If that project is not underway, then, it could be used for other capacity and safety improvements to Interurban (Southcenter- Grady), if none are in progress, then, the fees returned to Fort Dent. This is the same understanding developed for Homewood. RC /kjp File: Development File - Fort Dent III Homewood Suites dets-04Y 6'6° 41t) V) 4') 8. The applicant shall pay $147,000 to be used for the evaluation of widening the Interurban Bridge and approaches for dual left turns and pedestrians.

If that project is not underway, then it could be used for other capacity and safety iimprovements to Interurban ( Southcenter- Grady).

A 14' bench will be created at 18.3 (the 9,000 CFs level). The trail will be at elevation 24.5twhich will serve as a dike elevation for flood control. The first finished floor elevation will be 27. The standard project flood elevation is 22.3. The site drainage will outlet to the storm system in Fort Dent II which connects to the conveyance system in Southcenter Blvd. This system flows through Fort Dent I and outlets to the river. Touma Engineering completed calculations showing the pipe has capacity to handle all the expected 100 - year flow without detention for all the sites contributing to it. These calculations were reviewed for the Fort Dent II approval. As previously discussed with your office, the river widening is being proposed in lieu of onsite detention. The existing pipe has adequate capacity and no dentention is required.
