Responsible Official Position /Title Kjell Stoknes Director, Office of Communit Deve o.ment Date 2 /November 1977 Signature COMMENTS: WESTWATER MOTEL EXHIBIT•G CITY of TUKWILA OFFICE of COMMUNITY DEVELOPMENT MEMORANDUM 17 November 1977 TO: FILE FROM: Fred N. Satterstrom SUBJECT: Westwater Hotel Environmental Questionnaire and EIS for And- over Industrial Park /Andover East After reviewing the draft EIS Prepared by Wilsey & Ham, Co. for Andover Industrial Park /Andover East, I have discovered' the following: 1. The draft EIS covered that area known as "Andover East ". Andover East comprised about 82 acres and included the present Westwater site and the existing Jolly Ox Restaurant site. 2. The draft EIS analyzed the impacts of Andover East on the basis of commercial development. "Andover East will be developed in accordance with the City's M -1 Zoning Classification. The anticipated use of this site will be for commercial facilities." (SEE, p. 12 of the draft EIS). 3. The organization of EIS subsections in the draft EIS for Andover Park corresponds well with WAC 197 -10 -440 as do the required physical and human elements detailed in WAC 197 -10 -444. 4. The draft EIS was distributed in the summer of 1973 to agencies shown on the distribution list. 5. Responses to the draft EIS were received from the following: a. Environmental Protection Agency (EPA) b. Puget Sound Governmental Conference (PSGC) c. Corps of Engineers, Dept. of the Army d. Puget Sound Air Pollution Control Agency e. Washington State Dept. of Fisheries f. Washington State Dept. of Social /Health Services g. Department of Transportation, U.S. 6230 Southcenter Boulevard s Tukwila, WESTWATER HOTEL EXHIBIT H Memorandum File Page 2 17 November 1977 6. It is my opinion that the draft EIS would not be substantially changed on the basis of the abovementioned comments. There is no evidence that I can find to indicate that a final EIS was actually distributed. FNS /ch CITY of TUKWILA OFFICE of COMMUNITY DEVELOPMENT M E M O R A N D U M • 17 November 1977 TO: Kjell Stoknes, Responsible Official FROM:. Fred N. Satterstrom, Planning Supervisor SUBJECT: Westwater Hotel Environmental Checklist BACKGROUND: 18 October 1977 Westwater Management, Inc. applies to City of Tukwila for shoreline permit and conditional use permit.. Submits environmental checklist. 24 -27 October 1977 Westwater environmental checklist reviewed by Public Works (10- 25 -77), Fire Dept. (10- 27 -77), Building Dept. (10- 24 =77), and Police Dept. (10- 24 -77). 26 October 1977 Applicant submits letter stating his intention to locate heliport at the subject site. 4 November 1977 Planning Division requests additional information from applicant. 14 November 1977 Applicant submits requested information to Plan- ning Division. FINDINGS: 1. The size of the subject site is approximately seven (7) acres. 2. The proposed facility is a 250 -room, 7 -story hotel with 9000+ sq. ft. of banquet /meeting rooms, two restaurants, two bars, health club, retail shops, and swimming pool, and 400+ parking spaces. 3. The site has been filled in the past and earth changes will be primarily excavations for foundations and /or basements. 4. Emissions from vehicular traffic generated by the faiclity will add to the air pollution levels. 6230 Southcenter Boulevard • Tukwila, Washington 98188 • (206) 242 -2177 1 Memorandum Page 2 Kjell Stoknes 17 November 1977 5. The rate of surface runoff will be increased by the proposed facility and the rate of groundwater recharge will be decreased. 6. Tree growth on the site is limited to the unfilled portion lying along the river's edge. All of these large trees are cottonwoods. 7. Wildlife habitat is confined primarily to the shoreline area where underbrush and tree growth provide shelter. 8. Noise from construction activities will increase the ambient noise level at the site. Noise from pile driving activity will probably be the most noticeable. Following construction of the facility, the noise level'is expected to approximate the existing condition. 9. The subject site is located in an area zoned M -1 (Light Industrial) and planned for Commercial land use according to the recently adopted Comprehensive Land Use Policy Plan. As such, the proposal is consistent with present land use policy in the area. Surrounding land use includes a restaurant to the south, a restau- rant to the east, a single - family residence to the north, and industrial buildings across the river to the west. 10. Employment at the proposed facility may generate a need for addi- tional housing in the Tukwila area, and as a result, cause a slight increase in the population of the area. 11. Signalization of the intersection of Strander Blvd. and West Valley Highway is scheduled for summer 1978, according to the City's Public Works Department. Parking for over 400 cars is anticipated. Traffic generated by the facility is within the holding capacities of existing arterials. Also, according to the Public Works Dept., ingress /egress onto Strander Blvd. will be limited to right -turn in and right -turn out only. 12. The proposed facility will generate a need for additional police and fire protection. 13. The proposed facility will generate a need for water and sanitary and storm sewer utilities. Both public water and sanitary sewer are available to the site. Both are sized to meet anticipated demands. Storm sewer service will be provided by developer. The storm system will discharge directly into the Green River. 14. Proposed plans call for a seven - story, 80' high structure which "steps down" toward the river to a three - story, 35' high level. A building of such height will be conspicuous when surrounded and located in an area characterized by single -story industrial and commercial buildings. The proposed height, however, is well within limits allowed by M -1 zoning south of Interstate 405. Memorandum Page 3 Kjell Stoknes 17 November 1977 15. The applicant has indicated that the shoreline area will not be open to the general public for recreational use but, rather, is open to hotel guests. 16. This site has been included in a previous environmental impact statement, i.e., the draft EIS for Andover Industrial Park/ Andover East. (The subject site and the Jolly Ox site comprised what was known as "Andover East. ") This EIS was distributed in the summer of 1973. In this EIS, Andover East was evaluated on the basis of development to commercial facilities (SEE, p. 12 of that document). CONCLUSIONS: 1., The environmental questionnaire for the Westwater Hotel and the draft EIS for Andover Industrial Park /Andover East are hereby incorporated as part of this report on potential impacts of the proposal. 2. By virtue of the draft EIS for Andover East in 1973, the proposed project has probably complied with the procedural requirements of SEPA. (The organization and required elements of this 1973 EIS are nearly identical to those required in existing SEPA guidelines.) 3. While the scale and intensity of proposed development are relatively high, no major or significant pollutional impacts are anticipated as a result. RECOMMENDATION: Based on the above FINDINGS and CONCLUSIONS, I recommend that a negative declaration be issued for the proposed Westwater Hotel project. FNS /ch November 11, 1977 Dear Mr. Satterstrom: Regarding the additional information you require for further consideration of the environmental check list for our Westwater hotel, attached and enclosed please find all the supporting mat- erials you have requested. Please do not hesitate to call me if clarifica- tions are needed or additional information is desired. Respectfully submitted, Dona '— Cru1c-kshank Westwater Hotel Representative DCC /few Mr. Fred Satterstrom Planning Supervisor City of Tukwila 6230 Southcenter Blvd. Tukwila, Wash. 98188 3000 SOUTH 176TH - SEATTLE, WASHINGTON 98188 - (206) 246 -9110 Mr. Fred Satterstrom Page two November 11, 1977 Additional information requested pursuant WAC 197 -10 -333 3. Water. Although plans are not complete for the site develop- ment it is anticipated that average ground elevations in parking lots and site areas will be approximately 26 (MSL). On this basis the area grades would vary between lows at about 25.5 highs at about 26.5 which indicate that the drain- age system will function at full efficiency with river levels up to about elevation 24. The river water level for a 1:100 year flow occurrence in this area is estimated by the Corp of Engineers to be approximately 21.8. The system will func- tion under this occurrence. When the river level rises above elevation 24 the capa- city of the system will decrease slowly until, at a river elevation of about 25.5, the drainage system will begin to pond water over catch basins in the low areas. The Corps of Engineers is authorized to discharge up to 12000 cfs from the Howard Hansen dam, if it is deemed neces- sary, due to conditions in the dam area. This dam release plus local inflow downstream from the dam is estimated by the Corps of Engineers to result in a water surface eleva- tion at the site of approximately 26 . At this point the on -site drainage system will not function and low areas of the site will pond water. This ponded water will result not only from rainfall, if any, directly on the site but from river overflow waters entering the site from lower areas along the West Valley Highway and adjacent land, not pro- tected by high banks. 4. Flora. No significant vegetation will be removed in the area lying within SO feet of the rivers edge. Significant vege- tation - 12 inch diameter and over, is shown on the attached site map. The remainder of the growth below the top of the bank would generally be left in place with possible prun- ing. Any vegetation removed would be replaced as part of the site landscaping. There is no vegetation above the top of bank other than weeds and vines. The area would be fin- ished as part of the landscape program. • Mr. Fred Satterstrom Page three November 11, 19.77 6. Noise. Noise from construction equipment varies with the type of equipment and engine RPM. Normal noise levels are about 90 dBA at 50 feet for bulldozers and power shovels operat- ing at moderate engine speeds. Dump trucks generate 80- 85 dBA at 50 feet when accelerating from a standing start. Pile driving equipment can be expected to generate about 90 -100 dBA at 50 feet, however this noise intrusion would be intermittent and would occurr only during a period of approximately the first 30 days. Most construction noises are of low frequency and attenuate rapidly. These noises also possess a low annoyance factor when compared to sounds of equal level at higher frequencies. Since the building will be centeralized on the site, noise levels conveyed to the West Valley Highway and Strander will be modulated. The trees along the river bank will les- sen the significant of noise carrying across towards the industrial buildings to the West on the North side to resi- dence adjoining will probably receive a higher noise level than elsewhere. We will be cooperative with our neighbors to minimize noise wherever possible, and without exception all construction work during our development would be dur- ing daylight hours. The expected noise (dBA) in the guest rooms at comple- tion would be at least 50dBA. Extensive "structural furnish- ings (wall treatment, carpet and drapes)- and fixture efforts are being taken to insure that the quality of room to room acoustics will be in keeping with the high quality of the hotel. 8. Land Use. Our hotel project should have a continuing effect upon growth in the area, particularly of a high quality character, since the property value will increase. Frequently as in other communities, a fine new hotel acts as a social necu- lus for related developments of a similar quality, such as superior restaurants, office structures and or hotels. 9. Natural Resources. It is proposed that water for the proposed ponds will be pumped from the Green River, filtered for use, and return- ed to the river. This proposal is subject to approval from the County Hydraulic Engineers and the State of Washington. In the absence of this approval alternate sources will be sought, probably from a small well, or from the public water supply. • • Mr. Fred Satterstrom Page Four November 11, 1977 10. Risk of Upset. Since the actual structural design is not completed at this time, it is the intention of the owner and archi- tect to utilize his inhouse engineering expertise in con- junction with a local structural engineering firm as the primary source of knowledge about local earthquake history. All precautions will be taken to exceed the minimum requir- ed engineering for anticipated stresses in the event of an earthquake. 13. Transportation /Circulation. Attached hereto is the development data for the origi- nal submittal to which is appended a diagram of projected ingress and egress patterns to the hotel site, with and with- out the signalization as tabulated below.

Existing utilities are shown on the attached site plan as they relate to the subject site. All lines are of ade- quate size and capacityto serve the proposed development. s 4 Mr.. Fred. Satterstrom Page Five November 11, 1977 18. Aesthetics. To diminish the dominance of the building, a burro will be built around the outer edge of the parking lot with gener- ous land scaping on the perefery, the sides of the building and all parking lot areas. This treatment will lessen the view of the building from the perspective on West Valley Highway and Strander, as well as from the property to the North. When looking at the building from the North, South and West side the sloping roof line (6 stories on down to 3 stories as it gets closer to the river) will provide an interesting architectural profile which diminishes as it cascades towards the large trees along the bank. 19. Recreation. As a result of my telephone conversation with you, since there is no law governing the use of the Shoreline on our property, it is our intention to leave this area open for the convenience of our hotel guests and others (the public) who may choose to avail themselves of our grounds. pe.tfully submitted, Donald C.

Saturday and Sunday will have lower volumes than experienced on the - "average weekday ". The peak demand at the facility including the Motel, dining room, and restkaurant will be in the order of 272 trips. Coincidently, the peak hour average weekday trip demand of 272 equals the minimum projected number of rooms in the motel. Further, the P. M. average weekday travel demand has not in- cluded the banquet facilities. The banquet facilities will probably experience a trip demand in the order of 100 vehicles per occasion. Consequently, peak trip demand to the entire site will amount to the following: Motel Dining Room Restaurant Banquet Room Total 246 7 19 100 372 The peak demand used herein is the peak hour of the street system and not necessarily the the peak of the facility. It should be noted that these are anticipated hourly demands by vehicles. Consequently, the probable demand for parking will _ h be in the order of 370 stalls. It has been noted that without variance, the City of Tukwila zoning requirements provide for 418 stalls. With a variance the number of stalls may be reduced to 336. It would be our recommendation that no fewer than 370 stalls be provided. 4 WESTWATER TRAFFIC DEMAND as Percent of Approach Volume West Valley @ Strander Blvd. TIME 12 :00 - 1:00 1:00 - 2 :00 2:00 - 3:00 3:00 - 4:00 4:00 5:00 5:00 - 6:00 6:00 - 7:00 7:00 - 8:00 8:00 9:00 9:00 - 10:00 10:00 - 11:00 11:00 - 12:00 12 :00 - 1:00 1:00 - 2:00 2:00 - 3:00 3:00 - 4:00 4:00 - 5:00 5:00 - 6:00 6:00 - 7:00 7:00 - 8:00 8:00 - 9:00 9:00 - 10:00 10:00 - 11:00 11:00 - 12:00 Total SB% NB% EB% 1.33 1.61 0.70 0.62 0.49 0.70 0.21 0.37 0.35 0.21 0.25 -0- 0.31 0.12 0.35 0.92 1.11 -0- 6.77 5.32 1.05 14.25 9.14 1.74 10.15 6.18 3.48 5.33 4.33 3.83 5.0.3 4.70 4.88 5.54 5.69 7.32 6.26 4.70 8.71 5.13 4.82 7.67 6.15 5.69 8.71 7.79 11.24 8.71 8.92 15.44 11.50 5.54 8.53 11.49 2.67 3.43 5.57 1.44 '2.72 4.53 1.64 1.36 3.14 1.33 0.87 3.48 1.23 0.99 1.39 1.23 0.99 *0.70 100.00 100.00 100.00 Source: Washington State Highway Department. 5 • Existing Traffic The principal intersection, and the intersection adjacent to the site, is the West Valley Highway at Strander Blvd. The . traffic volumes on this facility are as follows: 1977 Average Daily Traffic Intersection Leg ADT A.

Assignment There is no data available at the present time for determining the percentage of trips which would be utilizing the site from existing traffic versus trips going to the site as "new traffic". New traffic, in this case, is that traffic attracted to the site and not presently in the area. Existing traffic is considered to be 60 percent and new traffic is considered to be 40 percent. Distribution The distribution of trips is assumed to be as follows: Distribution Orientation Percentage North 40 percent South 20'percent West 40 percent It should be noted that those trips oriented from the south will arrive at the site by turning left at the traffic signal and entering the site on the Strander Blvd. driveway. However, that traffic exiting and destined to the south - -the reverse component - -will exit the site onto West Valley Highway. This 6 • • assumption is based on the probable installation of channeli- zation precluding northbound traffic crossing the intersection and gaining access to the site from the West Valley Highway intersection. Traffic to and from the north and traffic to and from the west will enter the site via the West Valley Highway driveway and the Sttander Blvd. driveway respectively. 7 4 November 1977 • CITY of TUKWILA OFFICE of COMMUNITY DEVELOPMENT Mr. Don Cruickshank Westwater Corporation c/o Jet Inn 3000 South 176th Street Seattle, Washington 98188 RE: ENVIRONMENTAL CHECKLIST FOR WESTWATER HOTEL PROPOSAL Dear Mr. Cruickshank: Our office has just completed an initial review of the environmental checklist submitted for the abovementioned project. In order to make the threshold determination, it is necessary for us to request additional information (pursuant to WAC 197 -10 -333). The points on the checklist where this office needs clarification are the following: 3. Water. It is stated in the checklist that "all storm water runoff presently running overland and in earth channels ... will be collected in a con ventional underground drainage system with catch basins for silt and debris collection and will be routed through an oil separator prior to discharge into the Green River." What level will the river be at when discharge of storm water from the subject site will be impossible? How often can we expect this river level? What will be the effect of "no discharge" due to high river level? 4. Flora. Will any trees or other significant vegetation be removed in the area lying within 50 -feet of the river's edge? If so, please map their location and explain the reason for removal. Noise. What will be the effect on the ambient noise level of construction activity associated with development of Westwater? In addition, what is the expected noise level (in dBA) in the hotel rooms once completed? 6230 Southcenter Boulevard n Tukwila, Washington 98188 a (206) 242-2177 Mr. Don Cruickshank Westwater Corporation Page 2 4 November 1977 8. Land Use. Will the location of the proposed Westwater project on this site have any effect on the trend of land use in the general vicinity of the project? Will it attract other complementary and /or supplementary uses? 9. Natural Resources. Where will the water in the proposed ponds come from? The Green River? Public water supply? 10. Risk of Upset. The location of a tall structure on all alluvial floodplain theoretically can cause problems during earthquakes. How does this project respond to earthquake conditions? What precautions have been taken? 13. Transportation /Circulation. Please submit to us a traffic plan indicating ingress /egress patterns to the site and turning movements off of and onto West Valley Highway and Strander Boulevard. Particular attention should be made to channelization on West Valley Highway for left -turn movements. Allow for both conditions: with and without signal light at intersection of Strander and West Valley. 16. Utilities. Where are the utilities located in the relation to the subject site? Are the sizes of water and sanitary sewer utilities adequate? 18. Aesthetics. It is stated that the hotel is "low- profile ". Yet, the building at its proposed height will likely dominate the general area. What steps are being taken to diminish this dominance? 19. Recreation. Will the shoreline area be open to the public or only to hotel guests? If you have any questions concerning any of the above, please don't hesitate to call. The environmental review will remain in limbo until we receive a written response to the above questions. Fred N. Plannin FNS /ch atterstrom Supervisor 1 P1/(',e October 26, 1977 Dear Gary: As was mentioned at the time of our submission of plans and application, it is our intention to include a heliport as a part of the Westwater Inn.

We understand that the hotel will be a "U" shaped structure with the portions of the hotel housing the rooms ranging from three to five or six stories in height. We understand that the taller portion of the hotel will be near the east end of the complex and will step down to a three -story height at the end near the river. We further understand that the latest design concept will accommodate all required parking as surface parking outside of the building area so that no basement or partial basement parking is planned. We believe that a structure of this size will require pile foundations. The variation in intensity of load which will be realized beneath a continuous mat foundation supporting a structure of varying height is expected to result in significant differential settlement between the different loaded areas. This differential settlement would be accen- tuated if the higher rise portion of the building is located in the vicinity of Test Pit 10. Also the loads imposed on a mat foundation supporting a six -story building man be sufficient to result in an over- stress condition within the layer of softer soils which was encountered in Test Pit 10. • • DAMES 8 MOORE Westwater Corporation October 6, 1977 Page 2 We recommend that further investigation of soil conditions within the building area be conducted. This investigation is, in our opinion, necessary to provide further information on soil conditions at depth to permit assessment of pile foundation requirements as well as expected settlement behavior under the selected foundation type. The soil con- ditions revealed by previous investigations of this property indicate that there are no undue problems with respect to obtaining satisfactory foundation support for the proposed hotel; however, it is important that supplemental data be obtained for specific design needs. We have completed Section II.1 of the City of Tukwila Environmental Checklist, as requested. Where explanations are necessary, these have been provided as an attachment to this letter so that they can be attached directly to the checklist.

The site is bounded by Strander Boulevard on the south, the West Valley Highway on the east, and the Green River on the west. We have previously performed a soils investigation on this site, the results of which were presented in our report dated July 12, 1973. We understand that a copy of this report has been made available to you. The,:hotel structures will be located in the area defined by a setback of 200 feet from the streets and 50 feet from the Green River. The layout of the hotel has not been finalized but is expected to consist of one or more three -story structures housing rooms and a one- or two -story structure for the main lobby, restaurants, meeting rooms, and other public areas. Consideration is also being given to providing parking in a partial base- ment beneath some of the structures. Using assumed values for structural decd and design live loads, we have estimated that column loads, assuming a 20 by 20 foot spacing, would be on the order of 300 kips. If supported . on a mat foundation, an average areal load of about 1,000 pounds per square foot is anticipated. The soil conditions revealed by our earlier work are relatively uniform consisting generally of a few feet of softer silty soils over a moderately loose to moderately compact clean sand formation which extends at least • DA 9'4 I: r1: o zrz L Westwater Corporation September 21, 1977 Page 2 50 feet below grade. An anomalous situation exists in the vicinity of Test Pit 10 which is near the easterly limits of the building area. In this exploration the surficial silty soils extended to the full depth explored and could not be penetrated by the equipment being used. Thus, the thickness of these soils may be considerably greater than shown on the log of this Test Pit. The upper silty soils are relatively compressible while the underlying sand possesses low compressibility characteristics. Subsequent to submission of our earlier report, the site was filled up to approximately Elevation 25 to 26 by the placement of compacted fill so that at the present time the site surface is essentially level at this grade. For a building of the size planned, support on'shallow footings using a soil bearing pressure on.the order of 2,500 pounds per square foot would be feasible only with the implementation of overexcavation and replacement ,so that at least four feet of structural fill immediately underlies each footing and separates the footing from any softer underlying silty soils. This overexcavation should not be required on the north and westerly por- tions of the site where there is sufficient compacted fill unless the floor grade is depressed below the present ground surface. Generally, footing settlements under these circumstances are expected to be on the order of 1/2 to 3/4 inch. Unfortunately, a considerable amount of the softer silty soil would still remain in place utilizing this plan in the vicinity of Test Pit 10. We estimate that differential footing settlement between this and the more typical, nearby areas could be on the order of 1 inch in about 50 feet. It is our opinion that this may be more than could be tolerated structurally by a building of the.type planned. Supporting the entire structure on a mat foundation should provide greater structural rigidity with more ability to "bridge over" the area of poorer soils in the vicinity of Test Pit 10. The use of a mat foundation with four' feet of structural fill beneath the mat does not, however, alter the situation relative to differential settlements in the vicinity of Test Pit 10. Utilizing a mat, we still estimate that differential settlement across the mat between the vicinity of. Test Pit 10 and more typical nearby areas could be on the order of 1 inch in about 50 feet. One solution to this situation for either footing or mat support would be to avoid locating structures in this area. In order to evaluate such a plan accurately, further field explorations would be required. It is our opinion that avoiding the problem area in the vicinity of Test Pit 10 represents the most feasible means for achieving successful support of the buildings' using shallow foundations. Westwater Corporation September 21, 1977 Page 3 We have reviewed the estimated 100 -year flood level for this area (information obtained from the King County Flood Control Commission) to assess the practicality of a partial basement. This flood level is at approximately Elevation 26. The Commission recommends 2 feet of dike or yard grade freeboard above this level. Obviously, river levels may approach this elevation on many occasions during the course of 100 years-. Due to the primarily clean granular nature of the native soils in this area, it is our opinion that high river levels would be.quickly reflected by high ground water tables on the subject site. The possible consequence of an extended period of high water could easily be the flooding of a below -grade parking. area. These occurrences would be only occasional and of temporary duration. Nevertheless, we feel that the possibility of such flooding should be recognized in any planning which contemplates construction of a public use area or other building facilities below the present site grade. It should also be recognized that the use of a subgrade parking area will mandate the use of fairly widely spaced columns. This would probably eliminate the possibility of using a mat foundation. Somewhat greater footing settlements should, therefore, be expected; however, if the vicinity of Test Pit 10 is avoided, these should be relatively uniform. We trust that the foregoing information will serve your present needs. If additional information is desired, please contact us at any time.
