DRAFT ENVIRONMENTAL IMPACT STATEMENT FOR TUKWILA HOTEL PREPARED„aL THE CITY OF TUKWILA TUKWILA PLANNING DEPARTMENT TUKWILA, WASHINGTON WITH THE ASSISTANCE OF R.W. THORPE AND ASSOCIATES Prepared in Compliance with The State Environmental Policy Act of 1971 Chapter 43.21c, Revised Code of Washington, as amended SEPA Guidelines, Effective January 16, 1976 Chapter 197 -10, Washington Administration Code, as revised City of Tukwila Ordinance Number 1211 May, , 1982 to Summary A. The Proposed Aclton The project sponsors propose to develop a 5.47 acre parcel for an 8 story hotel at the southwest quadrant of West Valley Highway and South 158th Street. The proponent is proposing to develop a 274 room hotel with dining room, cocktail lounge and banquet facili- ties. A swimming pool will be available for hotel guests. A pedestrian bridge may be constructed connecting the hotel to Chris- tiansen Trail across the Green River. The completed hotel will rise approximately 92 feet above the existing grade. The proposed building will cover 30,715 square feet, or approximately 13 percent of the site. Paved areas will cover approximately 69 percent of the site. The remaining 39,315 square feet, or 18 percent of the site will be landscaped. The proponent also intends to landscape an additional 32,800 square feet along the riverbank and along the street frontage. The exterior of the building w i l l be surfaced with painted con - ete, and /or painted Portland cement plaster, and solar bronze ndows. A combined total of 509 parking spaces will be provided. The proposed development of the site will include associated im- provements and amenities, including floodproofing the building by raising its elevation with fill and constructing dikes.

Zontng Ordinance : LIU Qf ¶ukwf t The City of Tukwila has updated the Zoning Code to better reflect the goals and policies of the 1977 City of Tukwila t) 1 Comprehensive Land Use Policy Plan. The City Council adopted jthe new zoning code in May 1982. The previous zoning des i gna- (-c )3 tion for the subject site was Tight industry (M-IL The zoning POIiCieS map now designates the site as Regional Retail (C -2). The proponent has obtained preliminary approval to waive the height restriction in order to construct the proposed 8 story hotel. Prior to construction, Final Waiver approval and Board of Architectural Review will be required. Comment The proposed development will be in conformance with the Tukwila Zoning Code upon approval of the Final Waiver, and Board of Architectural Review. 3. Siorettne Management Program The Washington State Shoreline Management Act applies to that portion of the site within 200 feet from the ordinary high water mark of the Green River. The law stipulates that a permit must be obtained from the City of Tukwila for any substantial development occurring within this zone. The Green River has also been designated as a "Shoreline of Statewide Signifi- cance." Within shorelines of this designation, the City has been entrusted to ensure that development w i l l preserve the natural character, ecology and resources as we l l as increase public access to the shoreline. The Shorelines Management Act is directed at enhancement of shorelines rather than restric- tion of use. The Shoreline Master Program for the City of Tukwila desig- nates the entire Green River ShorelinE as an "urban environ- ment" which allows high intensity land uses including resi- dential, commercial and industrial development. The City of Tukwila classifies the 200 foot shoreline into three manage- ment zones: the river zone is 40 to 50 feet from the mean highwater line; the low impact zone-is outside the River zone and within 100 feet of the mean high water I i ne; and the high impact zone is outside the low impact zone and extends 200 feet from the mean high water line. Refer to Appendix D -. General Regulations. Comment The site plans of the proposed development are in conformance with the General Regulations as listed in Appendix D. The building and parking lot sha l l be constructed beyond the 40 foot.River zone setback line. • • Pile lengths could range from approximatly 80 to 125 feet, measured from the existing ground surface. Piles should pene- trate into the dense soils below the compressible clayey silt. A maximum of 83% of the topsoil of the site w i l l be reworked and covered with the building structure and parking lot, thus losing its current productivity. Some erosion of the fill material and worked natural soils is likely prior to construction of the building. The potential exists for water to seep into the foundation cut during con- struction, requiring temporary drainage. The movement of heavy earth moving equipment over the surface of the site during construction w i l l compact the so i 1, causing some pooling of water during periods of precipitation. This condition, coupled with the removal of vegetation, may contribute marginally to erosion of surficial soils. Existing levees along the stream - bank will have to be protected during construction to minimize the potential for streambank erosion. It is likely, however, that grading and landscaping near the streambank will precipi- tate some erosion of soils beyond the control of the procedures utilized to minimize erosion. Mitigating Measure 1. Earthwork and paving should be scheduled for the normally dry weather months. If this is not possible, at all times, the recommendations of the soils engineer regarding.earth - moving procedures applicable to periods of wet weather will be followed. 2. Test piles will be driven across the site to determine pile lengths and driveabiiity, pile driving hammer and capacity. 3. A temporary runoff control system, including ditching, sumps, and pumping from the excavation cut should be em- ployed by the building contractor. 4. All of the recommendations of the soils engineer regarding soil bed preparation procedures will be followed. 5. The City's requirements on grading and excavation will be followed. 6. The proponent will install and maintain a vegetative buffer between the area containing the parking lot, fire lane, and the shoreline which will provide erosion control and serve as a barrier impeding human activity along the shoreline. Unavoidable Adverse impacts 1'. The reworking and Toss of productivity of a maximum of 83% of the topsoils of the site. 2. Potential for minor uncontrollable erosion of soils near streambank during construction of driveway and parking lots adjacent the streambank. Oh 3. Potential for minor erosion of . soils near streambanks due to potential presence of human activity. c. Topography Existing conditions The site is very level, averaging 24 feet and varying only three feet in elevation. The top of the levee, along the river bank is generally two to three feet higher than the center of the site, however, along much of the south side there is very little variation in elevation. Fill material into the "River Zone" is not an allowed use ex_ceat for those uses described in the City of Tukwila Shore= line Master Program, Use Regulations (See Appendix D). impacts Topographic changes ranging from 2 to 10 feet will occur due to excavation and filling during construction. These changes will occur in order to construct a basement, and provide floodproofinq (i.e., dikes and fi I l to raise elevations above the maximum discharge elevation of Howard Hansen Dam. See Unique Physical Features, page 28). The building and parking lot sha l I be constructed beyond the 40 foot "river zone" set- back line. I`1 iti gat ing Measures None. Unavoidable Adverse impacts Changes in the contours of the site, including excavation depths of a maximum of 10 feet. d. unique Physrcat Features Existing Conditions Due to the proximity of the Green River to the site, the potential of flooding is increased. Consequently, dikes have been constructed along the bank of the river. King County Hydraulics Division reviews applications for State Flood Con- trol permits. The proponent of a development adjacent to the River is required to provide dikes, or build at an elevation 2 feet above the maximum discharge elevation of the Howard Hansen Dam (27.8 feet). • • The sulfur dioxide levels measured (for 1980) are well below Washington State standards. According to Stuart Clark of DOE, sulfur dioxide is not anticipated tobea problem in Tukwila. Levels there should be equal or better than those recorded at the Duwamish Pump Station. Sulfur dioxide levels are typically high near pulp mills, or smelters; automobiles emit very little sulfur dioxide and are not considered as a source by the Department of Ecology. (Telephone conversation with Stuart Clark, De- partment of Ecology, March 2, 1981.) Impacts 1. Short -term generation of particulates will occur as construction commences. Dust particles would be raised by earthmoving activities. Suspended particulate con- centrations which already exceed Washington State Stan- dards will further increase due to project development. However. air quality impacts are not site specific and would occur regarO ess of project site location., 2. Noxious odors would be emitted by diesel powered ve- hicles and from asphalt paving operations. 3. Some long -term increases in motor vehicle generated pollutants will occur due to the traffic generated by the proposed projects. Impacts would be most severe at identified points of congestion. Higher pollutant concentrations could cause air quality standard viola - tions to occur or persist longer than if no development were constructed. 4. Based on the "Simplified Analysis Technique for Estab- lishing Carbon Monoxide Concentrations Near Highway Facilities," the maximum levels of carbon monoxide during the peak traffic movement hour created solely by the proposed project will add approximately 1.1 ppm of carbon monoxide to the existing l e v e l s . Levels w i l l decrease with wind speeds in excess of 2 mph and with distance from Southcenter. Cumulatively, carbon monox- ide levels will be significantly less than the 1 hour maximum standard of 35 ppm. Furthermore, as more stringent federal motor vehicle emission controls take effect, there could be an overall decline in vehicle- related pollutants. 5. Increase in violation of Washington State standards for levels of hydrocarbons will occur due to the cumulative effects of this and other projects which generate auto- mobile traffic. However air quality impacts are not I ogaJ i zed and would occur regardless of project site location. Mitigating Measures 1. Low - emission construction equipment could be used when- ever feasible. 2. Measures to control construction dust such as: water- ing, cleaning and sweeping of streets at the end of hauling activities could be performed by the contractor. 3. Unnecessary motor vehicle engine idling during con- struction could be el i m i nated; engines could be shut off except when moving vehicles. 4. See Public Transportation' - Impacts relating to "Traffic," page 54. Unavo idabl e Adverse impacts 1. Increased air pollution from automobile emissions will contribute to hydrocarbon levels which already exceed. Washington State Standards. 2. Increased particulate levels, which already exceed Washington State Standards: due to construction ac- tivity and additional traffic volumes. b. Odor Existing Conditions The site is currently devoid of any discernible odors, except for potential occasional odors attributable to sheep grazing on site and north of the site, and odors emanating from the adja- cent river bed during periods of low stage. Impacts 1. The hotel restaurant exhaust fumes may contribute mar- ginally to odors perceived on the site. 2. Automobile exhaust fumes will be perceived along the en- trance driveway and parking areas. 3. Over the short term, significant odors will be attributable to construction vehicles, dust, and asphalt paving during the construction phase. Mitigating Measures None. llnavoidabl a Adverse Environmental impacts Short -term odors during construction. 3. WATER a. 5ffilAg.2 NELTI grffigliitaatigad2 Extst-i-nq Conditions The subject property is adjacent to the Green River. Man -made dikes protect the site and general vicinity from flooding from the Green River. However, due to the dikes, internal drainage is restricted from flowing into the river with resultant pon- ding during heavy rains. The level of the Green River is regulated by the Howard Hanson Dam, approximately 35 miles upstream from the project site. The flood l eve l of the river is thus dictated by the maximum discharge of the dam. The maximum flood stage of the river at the site has been determined to be at elevation 25.8 feet. The major portion of the site lies within this flood plain. The site l i es within the Green River flood contro l zone. A permit for any development within this zone must be obtained from the King County Hydraulics Division, acting as the dele- gated authority for the State of Washington. The subject site is located in an area designated "floodway fringe" where new development is only allowed when the King County Hydraulics -Division determines the development has adequate floodproofing for a 100 year storm. In accordance with the direction of the Tukwila Public Works Department, storm drainage runoff will be filtered and chan- neled into the Green River. The present policy is to move surface water runoff, from properties adjacent to the river, into the river as quickly as possible for the purpose of drain- ing those lands before the river reaches its flood capacity of 12,000 cfs (controlled by Howard Hanson Dam). :impacts In conformance with the State Flood Control Permit require- ments, fill material will be utilized to bring building eleva- tions above 100 year flood levels. A substantial increase in surface water runoff volumes would occur due to the creation of paved areas over approximately 82 percent of the site. This surface water will be collected in a storm drainage system and 3) LigeLlebil r J eS emptied into the Green River at the same rate as presently + exists in its undeveloped state. Since the site has previously been diked, surface water was prevented from draining into the River, increasing potential of flooding. The proposed development will decrease this poten- tial by pumping surface drainage water into the river as quick- ly as possible. Although this drainage system will be designed in accordance with City and County regulations, the system could contribute marginally to . peak river flows due to the • • runoff from impervious surfaces. Although the level of the river is controlled by the Howard Hanson Dam, minor uncontrol- lable fluctuations in river flow could contribute to minor streambank erosion downstream from the system outfall. The potential also exists for minor uncontrollable erosion of surficial streambank soils into the river during construction and landscaping. M i ti gat'i-nq Measures 1. Fill material will be required to floodproof building sites which will prevent on -site flooding. 2. A stormwater detention system designed for a 10 year storm capable of detaining 8,252 cubic feet of water is proposed W'ter/U-111 I eS to be installed. Stormwater will be stored in oversized pipes under the parking lot and detention areas (depres- sions) on the parking lot. The gravity flow system is designed to discharge stormwater into the (reen River at the same rate as the existing discharge rate. The City of Tukwila shall approve stormwater drainage plans prior to issuance of the building permit. 3. A temporary storm management system and the erosion control measures discussed under the "Soils" section, page 25 will be employed during construction. 4. Where possible, natural vegetation for silt control shall be maintained. 5. Temporary siltation and detention ponds shall be constructed by placing straw bales across swales. 6. All temporary siltation ponds shall be maintained in a satisfactory condition until such time as cleaning and /or construction is completed and the permanent drainage facil- ities are operational. 7. Rip -rap base (both sides) of bales sha l I be positioned as required for erosion control. 8. Cleaning of streets and parking areas shall be undertaken whenever necessary. 9. Frequent maintenance of the stormwater system shall be provided. Unavotdable Adverse -Impacts 1. A decrease in the - quality of the runoff from the site. 2. A potential increase in peak runoff from the site. fr EXISTING COTTONWOOD TO BE REMOVED TUKWILA HOTEL EXISTING MAPLE TO BE REMOVED EXISTING MAPLE C1 TO BE REMOVED TREES TO REMAIN W EST VALLE 1GHWAY TUKWILA HOTEL TUKWILA, WASHINGTON I TREE REMOVAL PLAN JENSEN KRAUSE & SCHOENLEBER ARCHITECTS & PLANNERS PC AIA /07 es, 110l0 le. /NW MBA=MeV .011711.110 ONOD• • b. Agrtcutturat Craps: The Green River Valley has developed as the primary agriculture region in the greater Seattle area. The general vicinity of the project site is in various stages of agricultural and post agricultural activities. Much of the land in the area has been previously farmed or grazed and has undergone urbanization through construction of manufacturing . parks, retail stores, roads, and residences. Sheep currently graze just north of and on the project site, where pasture makes up the majority of the land area. The fine sand and silty soils of the site, and within the valley are considered good for crop production, however, this area primarily supports pastures and hay l ands. Portions of the site which are not heavily grazed exhibit a succession of growth to pioneer brush and weed species. These small areas could be utilized for pasture, if replanted and continually grazed. Impacts Most vegetation within the property lines of the subject site will be replaced. Approximately 18 percent of the site will be landscaped with ornamental vegetation. Reconstruction of the dikes and construction of the fire access road will disturb some of the existing vegetation along the river. Mitigating Measures 1. A landscape plan has been prepared to assure good design practice and consistency throughout the site. 2. All vegetation along the riverbank, undisturbed by recon- struction of the dike and the fire access road, will be left undisturbed and maintained. All trees on the riverbank -'\ will be left undisturbed. (See Tree Removal Plan, page"E-- (/, Indigenous vegetation will be planted and maintained inside the dike so that the entire length of the hotel's river frontage is landscaped with natural vegetation. 3. In addition to the 39,315 square feet of planned landscaped area on site, 32,800 square feet off -site landscaping is planned. These areas include the riverside area and along West Valley Road. Unavoidable Adverse impacts Reduction of most of the natural vegetation on the site. 2. HOUSING Existing Conditions Housing in the City of Tukwila has increased 15.8 percent between 197Q and 1980 compared to 23.7 percent experienced in King C?unty. The 1980 Tukwila housing count was 1938 dwelling units. 11980 Census of Population and Housing Advanced Report - March 1981. Housing forecasts computed by the Puget Sound Council of Gov- ernments for the general vicinity are as follows: TABLE 8 HOUSING GROWTH Percent Percent Location 1980 1990 Change 2000 Change General Vicinity 2038 2631 29.1 2987 13.5 Vacancy rate for the subject area was approximately 1.6 percent in 1979. Based on projected housing and population growth for this area. Vacancy rates are expected to increase only slightly. Impacts. Project development will not significantly increase housing demand in the Tukwila area. It is expected that some of the employees will come from the area's unemployed ranks. Based on the City's ratio of 9.89 employees per dwel l inq unit, an i rte- e a s e of 17 5 emp Lay e_e s du p to Etat p 1 e nip 1 ny m.p nt w o u lSi Indicate an increase in housing demand by approximatly 18, housing units. This represents approximately .9 percent of the existing housing stock. Mitigating Measures None. Unavoidable Adverse impacts None. s ) i r s 4"I'0 • • appears that conditions along West Valley Road between Grady Way and South 158th Street deteriorate to an "at or near capacity" condition just prior to the opening of the track and following its closure. tmpacts Trip generation statistics by the Institute of Transportation Engineers and the Arizona State Department of Transportation shows the average trip generation rates for hotels and motels range between 10.1 and 10.5 daily trips per occupied room. During the weekday evening peak hour when traffic conditions are at their worst, the Tukwila Hotel would be expected to generate between .65 and .73 one -way vehicle trips per occupied unit. These trip generation rates reflect conditions where restaurants, cocktail lounges, meetings in banquet facilities, or convention facilities, and other retail and small shops are included as part of the hotel. When these trip generation rates were applied to the proposed Tukw i la Hotel, they yielded a total daily trip generation of 2,880 one -way trips. During the evening peak hour, the project is expected to generate. approximately 190 vehicle trips, with approximately 95 vehicles traveling inbound, and 95 vehicles traveling outbound. These figures assume the hotel is fully occupied on weekdays. During the weekend day, the Tukwila Hotel would be expected to generate between 750 and 1,300 vehicles per day. Further, typical weekend day /evening peak hour traffic volumes are sub- stantially lower than during the weekdays. In the project area, the peak weekend day traffic occurs during the mid- afternoon due to the traffic generated by the retail activity at Southcenter and due to the traffic generated by Longacres during the racing season. It is expected that approximately 55 percent of the daily traffic and 65 percent of the peak hour traffic generated by the proposed Hotel will travel north on West Valley Road. (See Figure A -22). The proposed .Hotel is expected to generate approximately a 7 percent increase in the daily travel along West Valley Road. During the peak hour, the volume along-West Va l I ey Road north of the site is forecasted to increase to about 125 vehicle trips per hour at evening peak hours, with the volumes being approximately equally split northbound and southbound, repre- senting a 4 to 6 percent increase. To the south, the increase amounts to less than 7 percent on a daily basis (1300 vpd) and less than 3 percent during the peak hour (20 vpd). (See Figure A -19.)

Peak traffic volumes at Longacres do not occur at the same time as the hotel peaks. However, traffic patterns generated by Longacres were examined to determine potential conflicts. It is estimated that between 500 and 750 vehicles per hour use the southbound turn into Longacres during its operation. The pro- posed project is expected to generate between 90 and 110 vpd with inbound and outbound volumes split about equally. The principal conflict appears to be between cars exiting the subject site (eastbound to northbound left turns) and cars making left turns into Longacres. The outbound left -turn vol- ume will amount to about one car per minute. Such a low volume would not cause a noticeable delay to Longacres traffic. Dur- ing the peak times, when traffic control is not provided by the Washington State Patrol, the exiting hotel traffic may not be able to find an acceptable gap in the traffic flow along West Valley Road, and motorists may become frustrated by the delay and travel south (turn right) to Strander Boulevard and make a "U" turn at the signalized intersection. Access to the site will be provided by two exit /entrances off West Valley Road. The first w i l l be opposite 158th and w i l l provide access for both right and left turns in and out. The second access lies approximately 370 feet south of the primary access. Traffic in and out of this entrance will be restricted to right turns only. Traffic entering the site will circulate to the north of the building under a canopy where baggage and passengers will be loaded and unloaded. The aisles for parking will serve as the internal road system. The proposal includes provision of a left -turn lane on West Valley Road at the northerly entrance to the site. A sketch illustrating the design is presented in Figure A -26. Based on an analysis of the daily and peak hour traffic volumes in the vicinity of the northerly entrance, the need for a traffic signal i s not warranted. While there w i l l be selected times when signal warrant criteria are satisfied (e.g., following Longacres closing), warrants cannot be met for the full 8 -hour 5.

Fire and emergency responses will be from the station located at 444 Andover Park East in Tukwila, approximately 1/2 mile southwest of the subject site. The Andover East station has three pumpers, one 100 foot aerial ladder, aid car and support vehicles, with full time personnel on duty 24 hours a day. The maximum emergency response time would be 2 minutes or less. Emergency medical aid will also be provided by the Andover East station by an aid car and person- nel.. The fire rating in Tukwila is class 4 in a scale of 1 to 10 with 1 as excellent. impacts According to a representative of the Tukwila Fire Department, the project w i l l increase the work load. (Refer to Appendix G for correspondence with Fire Marshall, Jim Hoei.) The proposed hotel _tgill rj se approximately 92 feet above existing grade and.bgtween 89 and 90 feet above finished grade. Mitigating Measures 1. The hotel will be fully sprinkled and conform with each standard delineated in the City of Tukwila's fire Protection Standards, Ordinance for High Rise Buildings, Number 1167. (See Appendix J) The Fire Marshal shall review the application prior to issuance of a building _permit to epure cnnfnrmancP +n Parh z +apr. _ 2. The proposed hotel is designed to have 2 passenger elevators and one service elevator in the middle of the building. A fourth elevator shaft will be provided for a future elevator if needed. Stairs on the north and south ends of the hotel will also be provided. 3. Tax revenues from the proposed development will help offset the cost of additional service. Unavoidable Adverse -Impacts Increased demand for fire service. b. Pottfce Service Existing Conditions Police protection will be provided by the City of Tukwila Police Department, located in the City Hal! less than three The Green River provides an important recreational feature adjacent to the site, both from the standpoint of a passive visual amenity, as well as for fishing. The City of Tukwila Park and Open Space Program (1976 -1981) does not identify any park needs in the general vicinity of the subject site. Goals for the Southcenter neighborhood in which the site is located are as follows: 1. "Encourage shopper and employee use of Christiansen Road." 2. "Encourage employers to provide some on -site recreational opportunity to employees." 3. "Encourage open areas In developments for the enjoyment of customers and employees." The Trails and River Park Concept of the Plan identifies either side of the Green River as a Riverfront Park. However, the Preliminary Park Plan for the section of River which the sub- ject site is on, does not show any park facilities on the east side of the River. impacts Project development may include a pedestrian bridge from the hotel to Christiansen Trail across the Green River. Additional demand could be expected on Christiansen Trail if the bridge is constructed. Attendance is expected to increase at Longacres. Passive use of the pro[ect's shoreline is proposed. The area between the area containing the parking lot, fire lane and dikes, maintenance road, and the shoreline is planned to be improved with the addition of groundcover, shrubs, and conif- erous and deciduous trees. Mitigating Measures 1 . The project w i l l provide a swimming pool and j acuzz i for use by hotel guests. 2. Tax revenues from the proposed development will help offset the cost of additional service. Unavoidable Adverse impacts None. d.

ARCHAEOLOGICAL /HISTORICAL °9› Existing Cond fti ons Duwamish Indians inhabited the Green River drainage system. Their v i l l ages often moved, forced by the changing course of the river, cultural preference for relatively clean surroun- dings, and the necessity to seek food and supplies as they became available. The Duwamish No.1 site, located downstream from the project area on the Duwamish Waterway, appears to have been occupied. The oldest dendro- corrected C-14 date obtained is 670 AD and the youngest is 1690 - 1800 AD. Another site, located along the abandoned channel of the Black River near Renton, was occupied somewhere between 200 and 1000. AD and again between 1900 and 1920. An archaeological survey was undertaken on the site. There is no indication from the survey of any archaeological significant artifacts on the site. (See Appendix C) -impacts Potential uncovering of archaeologically significant finds during construction. Mit'rgati ng Measures A qualified archaeologist should conduct on -site monitoring during land clearing, access road construction and building site preparation. Unavoidable Adverse Impacts Potential removal of an archaeological site. IV. UNAVOIDABLE ADVERSE IMPACTS So its 1.

Tower Seattle, WA 98101 Attn: Jon Potter SUBJECT: Working DEIS, Tukwila Hotel We thank you for the opportunity to review the subject document in advance of :formal publication. While the material contained in the working draft is gen- erally sound, we wish to call to your attention the need for some additional research and amplification of certain topic areas vis -a -vis the scope of work which we transmitted to the project architect on 28 October 1981: 1) EARTH - As an addendum to the geotechnical report appearing as Appendix I, please include the conceptual grading plan as requested in the scope of work. - Under section VI B 2 of the Wilson /Shannon report, the consultant recom- mends extending the preload mat to a distance of 25' beyond the edge of the outer building wall. Please note that extension of fill material into the river use zone is not an allowed use therein except for diking pur -. poses. This caveat should be explained at some point in the DEIS text. 2) AIR - While the statistical air quality data provided appears to be timely, we request that the text be modified to more distinctly isolate those portions of the narrative which pertain to certain or probable violations of air quality standards. 3) WATER /UTILITIES - We understand that the applicant's engineer is negotiating with the County Surface Water Management Agency to agree on an acceptable scheme for on- site storm water retention capacity. The results of that discussion should be included in the published draft, describing both the quantiative stor- age capacity required and the technology by which it will be acheived. 4) HOUSING - We disagree with your conclusion that opening of the new hotel will not increase demand for housing within the Tukwila community. There should be some narrative linkage between the housing /employment tabular data appear- ing on pages 48 and 49. Page 2 R.W Thorpe1Assoc. 5)TRANSPORTATION - The background material in the TRANSPO report is generally well -done; however, we would like to ahve a stronger quantitative discussion of of the project's traffic - related impacts at critical intersections re- lative to existing roadway levels of service. 6) AESTHETICS, - The view - obstruction diagram appearing on page 67 does not relate to the hillsides north of I -405 as instructed in the scope of work. 7) RECREATION - Under this heading, discussion of the use to which the project's shoreline and river - frontage shall be put should be included. Recreational improve- ments other than the footbridge and a listing of the unavoidable adverse impacts to the shoreline 'environment resulting from increased presence of humane activity are necessary..: 8) ARCHAEOLOGY -The "boilerplate" mitigation language on Page 69 should be changed to re- flect the on -site monitoring method suggested on Page 16 of the Geo -Recon report, Appendix "C ". 9) FLORA -A diagram illustrating those trees to be retained as part of the project should be included as an illustration of Mitigation Measure No. 2 on page 36. 10) RELATIONSHIP TO EXISTING LAWS,POLICIES... - Please note what enactment of Lhe rrew city zoning code, a con- ditional use permit is no longer needed for this project. 11) FIRE PROTECTION - Please discuss public safety impacts relative to building height as regard exiting, fire department rescue equipment and internal protection systems. Please note also the revisons to the title page which we request as shown on the enclosed example. TUKWIL ANNING DEPARTMENT M. ' Caughey Associate Planner en.cl MC /ibm .

We met with Mark Caughey yesterday to discuss the site plan for our hotel, to be adjacent to the West Valley High- way across from 158th Street. He advised us that if this ordinance is passed, we must change the location of our building, because a fire lane will be required between the Green River and our hotel. The effect of this ordinance is to prohibit any building from being located less than 60 feet from a river, when a fire lane is required. This change in location would reduce the number of park- ing spaces and therefore seriously impair the-use of our site. Also, it eliminates the view of the Green River from our restaurant. The fire lane we have planned within the 40 foot river use zone will blend with the landscaping and be a pedestrian way except in an emergency. • Page Two City Council City of Tukwila December 17, 1981 I request that you reconsider this ordinance and add an amendment which will allow access for fire protection purposes within the 40 foot zone.

Kearney Portland, OR 97209 Attn: Jerry Baysinger, A.I.A. Subject: Christensen Group Hotel Project E.I.S. As requested in your letter of 23 October, 1981, our office has reviewed the preliminary draft of your SEPA Environmental Checklist. The Planning Director, as responsible official, has determined that the project proposal will require preparation of an Environmental Impact Statement. Our decision to so- require is based on the following criteria: 1) The scale of the project relative to existing development in its immediate geographic vicinity. 2) The magnitude of change in land use suggested by the project relative to the site's present useage. The potential introduction of sigrtficant pollution sources into the project vicinity as a result of its construction and operation. In preparing the Draft E.I.S. document, we believe that certain topics should be "scoped" to emphaisze research and exposition of the most germain issues. Section WAC- 197 -10 -425 of the State Environmental Policy Act Guide- lines requires . that all matters of content specified in WAC- 197 -10 -440 must be included in a draft E.I.S. However, not all sections must be treated with equal gravity. Therefore, we have prepared the following list of items which should be addressed in greater detail: 1) Earth: - Grading and site preparation to includea conceptual grading plan, indicating locationaf cuts-and fills and estimates of material movement quantities. 2) Air: - Deterioration of ambient air quality as a result of project - related traffic should be quantified. Page -2- Jensen, Krause & ScIleber 28 October 1981 Water: • - A comprehensive, quantitative analysis of storm water retention and discharge to the river will be needed. 4). Light and Glare: - This topic should include a graphic study of potential glare paths to adjoining properties, West Valley Highway and I -405 during worst -case solar reflection conditions. Evening -hour lighting impacts from hotel windows and signing should also be studied., 5) Housing: - Analysis of project - related employee housing demand within the community should be presented in comparison to the existing vacancy rate for rental and saleable housing. 6) Transportation: - Perhaps the most crucial study - element of E.I.S. is a comprehensive traffic /transportationstudy. Intersection capacity, turning movements, peak -hour volumes and the like should be studied as to the way in which current conditions are influenced by the project. Public Services: - A project of this magnitude and heavily- oriented to human useage will impose additional public service demands on the City. Police and fire protection levels may be affected, as will existing public recreation facilities. Public cost impacts of the project compared to revenue generated should be analyrzed. Utilities: - As mentioned above, a comprehensive storm drainage study will be needed. 9) Aesthetics: - As this building will be among the tallest to be built within Tukwila, Graphic analysis of potential view blockages from the residential hillside north of I -405 should be included. 10) Recreation: - To include a detailed description of private recreation facili- ties to be included in the project, and anticipated use of nearby public recreation facilities. Page -3- Jensen, Krause & ScIppleber 28 October 1981 II) Archeological /Historical - Due to the recent discovery of historic and cultural artifacts in the Green /Duwamish River flood plain, we suggest that a comprehensive field investigation be conducted prior to E.I.S. publication. The Office of Public Archaeology, University of Washington will gladly provide technical direction and assistance in this topic area. You may contact their office at 543 -5240. Before beginning any formal work on preparation of the Draft E.I.S., however, we ask that you and your consultant team schedule a meeting with us so that all expectations and assumptions underlying this study can be clarified. Please call me if you have questions about the content of this letter. Tukwila Department Mark' Caughey Associate Planner MC /blk xc: Ping. Dir.

You -may' recall that a preli'mi'nary waiver for the project was granted earlier this year. The applicants are request- ing consultation with us', as lead agency', to-,determine the probability of our requiring an E.1.S. for the project (WAC 197 - 10:,300 (3)1. It is my opi'ni:on that we should in fact require the Environmental Impact Statement, but that its content should be " scoped' to emphasize research and exposition of the most germai'n issues. WAC 197 -10 =.425 requires that all matters of content specifi'ed in WAC 197-10 -440 must be included in a draft however, not all sections must be treated with equal gravity. Therefore, it becomes our task to prepare a listing of those areas of inquiry to be addressed in greater detail. In the Superior Court case of Norway Hill Preservation Association v. King County Council, the court established three criteria the presence of which in any project proposal should mandate E.I.S. review by the lead agency: ./ 1) The scale of the project relative to existing development in the immediate project vicinity. The magnitude of change in land use suggested by the project relative to the site's presence useage. The presence of significant pollution sources introduced into the project vicinity as a result of its construction and operation. I believe that factors representing each criteria are present in the Christensen application: The hotel project consisting of eight levels is certainly sign- ificant in scale relative to existing development patterns in Southcenter. As the ground is now used marginally as grazing and pastureland, the magnitude of use change is also significant. Finally, the presence of hundreds of automobiles on the site may generate significant air quality impacts, and the amount of paved surface has severe implications for water quality of the Green River.
