Mullet, Mayor Department of Community Development Steve Lancaster, Director MEMORANDUM TO THE FILE Date: June 3, 2000 To: Jack Pace, Planning Manager From: Alexa Berlow, Associate Planner RE: Shoreline Management Permit SHORELINE SUBSTANTIAL DEVELOPMENT Best Western Southcenter Annex Permit Number: L99 -0048 1. PROJECT DESCRIPTION: The proposed project is for a new hotel annex, to be located east of the existing Best Western Hotel. The annex is proposed to be built over a portion of the existing parking area. It will be comprised of 72 new guest rooms, with associated parking (232 stalls proposed), landscaping, and shoreline access. The new annex will include meeting rooms, a restaurant, and a lounge. The proposed building is located within 200 feet of the Green River, a shoreline of the State. The public recreation trail is accessible from the property, from access points located at both the north and south sides of the West Side of the proposed new building. The trail is also used as a fire lane. A joint access easement is located along the north property line, jointly owned by the Best Western and the Nelson Family Estate. This joint access easement extends from West Valley Highway, the main thoroughfare and access to the hotel, to the West Side of the Best Western property. A set of plans is attached. 2. BACKGROUND: The Nelson Family Estate has made verbal and written comments about the terms, conditions, and use of the joint access easement. Negotiations between the parties have been held, without full resolution at this point. Negotiations continue and are currently administered by the Planning Division. The City of Tukwila land use attorney has been consulted. Written comments were received by David Weitl, Estate manager for the property, in a letter and supporting documents dated August 17, 1999. The comments pertain to the joint access easement and public access to the recreation trail. Access is also required by the City of Tukwila Public Works Department for repair and regular maintenance. 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: 206 - 431 -3670 • Fax: 206 - 431 -3665 Best Western Southcenter — Annex Staff Report Shoreline Substantial Development Permit # L99 -0048 Page 2 3. POLICIES OF THE SHORELINE MANAGEMENT ACT (SMA)/ SHORELINE MASTER PROGRAM (SMP): The site is within the jurisdiction of the Tukwila Shoreline Management Program: (SMP). This program: was adopted in June, 1974 and amended March 16, 1982. The City's SMP was reviewed and approved by the State Department of Ecology as being consistent with the State Shoreline Management Act, adopted in 1971. Tukwila Shoreline Master Program The policies of the Tukwila Shoreline Master Program are categorized as follows: Economic Development; Public Access Element; Circulation Element; Recreational Element; Shoreline Use Element; Conservation Element; Historic Cultural Element; The proposed annex is intended to function as an extension of the existing hotel, to provide additional space for a viable existing business, located along Highway 181 in a general land use area of similar types of businesses. In addition, the hotel draws clientele to the restaurant located within the main building. The new annex will be located within the shoreline management zone. Public access to the river from the hotel is intended to be provided at two locations from the property. In addition, a joint- access easement that extends the length of the property will provide public access from Highway 181. There is also access to a public recreation trail from both access points on the property. This will provide recreational opportunities to guests of the hotel and to the public. The hotel currently houses 146 guest rooms. The annex will support an additional 72 rooms. Development along the shoreline will be limited to native plant materials, when necessary, in connection with building the bioswale. Otherwise, all appropriate measures will be taken to conserve existing plant vegetation along the riverbank. Measures to monitor and maintain the existing health of the riverbank is outlined in the Contingency Plan, prepared by S &EE on September 27, 1999. A copy of this document is attached. The visual impact of the development and surrounding area meets basic development requirements of the Tukwila Municipal Code. The proposed annex is subject to design review. Elements associated with this aspect of the proposed project will be addressed under the formal design review process administered by the Department of Community Development, Planning Division. 4. REGULATIONS of the SHORELINE OVERLAY The Shoreline Overlay extends 200 feet landward from the mean high water mark of the Green River through the City of Tukwila. The district is divided into three (3) categories: River Environment; Low Impact Environment; and High Impact Environment. The River Environment: This environment consists of the first 40 feet landward of the mean high water mark.

This includes a contingency and maintenance plan for the riverbank and the public access trail. The public access trail also provides access for the fire department. Access to the trail by guests and to the public will be provided from this area. The contingency plan is outlined to monitor, in addition to routine circumstances, conditions that could result in the loss of five (5) horizontal feet or more of the riverbank. Maintenance will also monitor any bank failure that results in an immediate threat to the fire lane and building. Riprap at the toe of the slope will be provided, as needed, as part of routine maintenance. Need for riprap will be evaluated by a geotechnical engineer on an annual basis. See Attachment B. Erosion control has been outlined in the conceptual utility plan, prepared by the American Engineering Corporation. Ostergaard Robinson & Associates, Inc have prepared an erosion control plan. See attachments for specifications on erosion control. Storm drain discharge is proposed by way of an existing storm drain. Storm water detention is not required, however, water quality treatment facilities are provided for both existing and future runoff. The Low Impact Environment: This environment consists of the next 60 feet landward of the River Environment. This area will be landscaped with shrubs, grass, and native planting. A bioswale is also proposed along the entire length of the river in the area behind the proposed annex. Existing parking and a landscaped parking island are part of the existing area. The landscape islands will also be augmented, to meet new landscape standards required under Ordinance # 1872. The High Impact Environment: This environment consists of the next 100 feet landward of the River Environment. The annex building is proposed for this area. The total site area is 6.03 acres. The building is proposed as a four -story structure. Rockery is proposed along the rear of the building, and low -lying shrubs and groundcover are proposed along the north side. A fifteen foot landscape setback is proposed at the front of the building, to be planted with a variety of native trees. General Shoreline Regulations All uses within the shoreline overlay district must conform to the following general rules, per Tukwila Municipal Code Chapter 18.44. Only rules, which apply to the proposed shoreline development, are addressed in this section: 1. The use is in conformance with the underlying zoning district, Tukwila Urban Center (TUC). Design Review is required to establish the proposed building. The Planning Commission, with conditions has approved this permit application. Revisions to meet the required conditions of approval will be under review prior to the submittal of the applicant's building permit. 2. A drainage bioswale will be built on the property, adjacent to the riverbank. A contingency plan has been outline by geotechnical engineer S &EE regarding maintenance of the shoreline and riverbank.

The project will require a Flood Zone Control Permit (per Flood Ordinance 1462), and a Storm Drainage Permit (Per Ordinance 1591). 4. There is wildlife habitat near the site. The property is in the vicinity of a type 2 wetland, located behind the Homestead Village hotel, two properties north of the proposed annex. Significant habitat has been and continues to exist. Measures to protect and preserve existing habitat will remain. Existing vegetation along the riverbank is intended to remain. 5. Solid waste facilities are located outside the Low Impact Environment. All other waste facilities are located outside the shoreline overlay zone. 13. Property for public use is dedicated to the owner. Access to the river for routine maintenance and repair, must be granted. See recommendation section of this document. 5. COMPREHENSIVE PLAN SHORELINE POLICIES The Policies of the Comprehensive Plan that affect this shoreline development are those outlined in the Shoreline Element. Goals and policies of this element include: facilitating the redevelopment of the Manufacturing/Industrial Center (MIC) and Tukwila urban Center zoning districts; increasing public access to the river; and increasing the amount of trees and landscaping in the river environment. Compliance with these goals and policies, as appropriate to the proposed development, are as follows: Public access to the river will be provided through the joint access easement, located along the north side of the property. There are two access points to the shoreline and public recreation trail from the property owned by Best Western. The northernmost property will provide access to the public from Highway 181. The southernmost access point will provide access primarily to guests of the hotel. All existing vegetation along the riverbank will remain unchanged. Stormwater from the site will be treated in a bioswale. Compensatory flood storage will be held in an existing basin. This basin is located on the property in an area outside the shoreline environment. Any erosion will be monitored through a contingency and maintenance plan, prepared by S &EE geotechnical engineers. Water quality treatment facilities are provided for both existing and future runoff of storm drainage. Riprap at the toe of the slope will be provided, as needed, as part of routine maintenance. Need for riprap will be evaluated by a geotechnical engineer on an annual basis. See attachments for reference to this plan.

This requirement applies to all buildings, existing or proposed. The Annex will require backflow prevention on the fire and the domestic water lines. If there is irrigation, the system will require backflow prevention. The compensatory storage may require safety design, such as fencing. Please refer to Chapter 5 in the 1998 King County Surface Water Design manual for safety design criteria. The City will request the following: Specifications for the metal roof materials to determine if all water quality needs are met. A more detailed erosion prevention and sediment control plan and the expected construction sequence. A copy of the non - residential sewer connection certificate. A site plan that meets the City's land altering and flood control zone site plan criteria. A copy of the swale maintenance covenant and a maintenance plan for the swale. The maintenance plan should be specific about who does what and where the records will be kept. A construction access and maintenance easement that provides immediate access to the riverbank. This access might also serve as a trail connection per Don Williams letter dated January 20, 1999. Do not confuse this access with the Nelson's access or fire department requirements. During the project permitting stage, Public Works will expect a more specific contingency and maintenance plan for the river bank. For instance, the plan should state specifically who does what, who is the focal for the contingency plan, how will the maintenance crew know the contingency plan exists, where will the contingency plan, maintenance records and the annual evaluations for riprap needs be kept and for how long, how will Best Western ensure maintenance and inspection gets done, 2 Q /jilt /projects /best western /shoreline comm 2 0.3.17.00 Page 2 posi f6vAJ 6i) and who has the authority to mobilize earthwork and shoring contractors? 3 Q /jilt /projects /best western /shoreline comm 2 0.3.17.00 D- 1-L Lam. h Subdivision Management Inc. r 16031 - 119th PI.

This resubmittal is in response to your letters dated October 29, 1999 and September 20, 1999, and a reiteration of responses to your letter of March 10, 1999. I am sorry for the delay caused by the amount of information requested and the workload of our consultants. • Responses to September 20, 1999 letter: 1. Temporary and permanent erosion control - Please note that the permanent erosion control plan showing sediment control be provided by water quality swale was included in the Conceptual Utilities Plan prepared by American Engineering Corporation. A new Conceptual Erosion Control Plan, based on the current drainage design manual, prepared by Ostergaard Robinson & Associates, Inc. is included in this resubmittal. The plan depicts silt fencing and CB protection. 2. Contingency plan in case of bank failure - A new Contingency Plan is outlined by Dr. C. J. Shin of Soil & Environmental Engineers, Inc. Dr. Shin recommends that the following procedures be adopted in the contingency plan: • Ms. Alexa Below Best Western Annex 11/30/99 Page 2 3 A. The hotel maintenance crew should prepare the following: 1). A list of earthwork contractors that are experienced in levee or dike repair. 2) A list of shoring contractors that can react to emergency events that require installation of steel sheet piles of up to 50 feet in depth. 3) A list of material suppliers that can supply fill materials including sand, gravel, and quarry rock. B. The hotel maintenance crew should inspect the river bank during and after any severe rainstorm. If any sloughing, slide, or failure along the river bank is observed, the hotel manager should be notified immediately. C. For any failure that results in a loss of 5 horizontal feet or more of the river bank, the situation should be evaluated by a qualified geotechnical engineer. The engineer should assess the risk of further ground loss, impact to the fire lane and hotel building, and recommend stabilization measures. D. For any bank failure that results in an immediate threat to the fire lane and building, the fire department and geotechnical engineer should be notified immediately. Depending on the situation, the earthwork and shoring contractors may need to be mobilized at once for installation of temporary shoring and dike stabilization measures. If the fire lane is dedicated to the city in the future, other pertinent authorities such as the Parks Department should also be informed. Please note that continuous maintenance of the river bank is desired and the maintenance measures may include placement of rip rap at the toe of the bank. It is our opinion that rip rap is not required at this time, but its need should be evaluated on an annual basis by a geotechnical engineer. Please see enclosed letter from Dr. Shin. 3. Discharging surface water into Green River - Direct discharge of existing and future storm runoff to Green River is will be via an existing 18" CMP storm drain located at the southwest corner of the site. See existing Type II CB, 18" CMP and riprap outfall on Conceptual Utilities Plan. Green River is classified as a "Receiving Body of Water" and no storm water detention is required. The proposed Annex does not increase the amount of impervious surfaces. However water quality treatment facilities are provided for both existing and future runoff. •z Z: re g. u6° • JU 0O N 0; w I..

Maintenance access - Maintenance access to the new Annex will be provided via parking areas around the building. Maintenance access to the existing building will be from the existing fire Zane /trail south of the building and via parking areas around the building. 5. River bank /fire lane /trail protection - Rip rap at the toe of the slope will be provided as part of the normal maintenance work. 6. Response to March 10, 1999 letter: Planning Division comments: A. Relationship of Structure to Site: It was pointed out in our September 29, 1999 meeting that the existing and new building are identical in use of fenestration, modulation and exterior finishes for the first three floors. Reconfiguring of the modulation on the new Annex means the buildings would look different therefore making the connection weaker between the two and reconfiguring the modulation of the existing building would be c_o_st_p_rohibitive. B. Relationship of Structure to Site and Adioininq Areas: It was agreed that passive recreation activities in the shoreline environment would be incorporated into the project, however, we are waiting for the parks department to acquire easements so the trail along the riverbank can be extended. The Landscape Plan revision dated May 3, 1999 had a note added to the west end of the trail regarding trail amenities to be incorporated per the city of Tukwila Parks Department. C. Landscape and Site Treatment: 1) The landscaping provided in the parking area exceeds that which is required. Our landscape design indicates five -foot wide landscaped islands at all head to head parking. This landscaping is in addition to the required landscaping but is provided so no stall shall be without landscaping. As we explained to you in our last meeting incorporating additional landscaped islands closest to the Annex would greatly interfere with the parking needed for large tour buses and therefore were not indicated on the plans. There is a note addressing this on the Architectural Site Plan. 2) Your letter of October 27, 1999 to Paul Dix indicated that the additional six (6) feet of landscaping has been waived. The existing one -foot strip will be planted as part of development. Ms. Alexa Below Best Western Annex 11/30/99 Page 4 3) After discussion and looking at alternate locations on the Site Plan it was concluded by all present that the present location shown for the trash dumpster enclosure is the best location. A design for the dumpster enclosure is submitted for review. D. Building Design: 1) Modulation was discussed under "Relationship of Structure to Site ". The Clock Tower is the Best Western's signature. It must be highly visible from the freeway. Zoning allows for a building height of up to one hundred fifteen feet. We indicate the Clock Tower height at seventy -two feet and eight inches. The height of the sloping roof is in good proportion to the overall mass and visually makes the Annex appear lower than a flat roof would. Also the height of the sloping roof will ensure screening of any roof top equipment from the freeway and from Embassy Suites. The eaves of the roofline on the Annex match the parapet of the existing building in order to create a strong connection between the buildings. The submitted building elevations indicate the introduction of other contemporary building materials such as stucco and metal roofing and pipe rails. 2) The original colored rendering as submitted was actually trying to portray the architecture of the building. The renderings were later revised to show how the Annex will actually appear by accurately putting in the new and existing landscaping and trees. The Annex is quite screened by all the trees and distance from the entrance to the site. Directional signs will clearly lead the way to the covered Main Entrance. Please see the new renderings submitted to you on May 14, 1999. Miscellaneous Structures and Street Furniture: 1) Submitted photographs of the existing entrance canopy at the pool area have the roof of the new connection superimposed on them. These photos clearly show that the new connection will be lower than the existing awning. The connection may be open or enclosed. If enclosed it will be entirely glass as the submitted building elevations show. 2) The new submittal does give detailed information on the signing. 3) The sloping roof proposed will screen any roof top equipment. z mow. 6 00 CO o; w i:.

A monitored fire alarm system will be installed per UBC 310.10 and Ord. #1742 as indicated on the civil site plan. Park Department Comments: Comments are incorporated into the landscaping comments. Public Works Comments: A. Shoreline permit application #L98 -0048 was found complete on July 28,1999. 7, New landscape ordinance The Conceptual Landscape Plan has been revised to reflect changes in the new landscape ordinance. The two forms, Landscape Declaration and Landscape Checklist, will be filled out at the proper moment after plan approval. 8. Existing access easement/parking A. Status of the easement—According to Exchange of Easement (AF No. 9111260669) "NENDEL'S TUKWILA ASSOCIATES, A PARTNERSHIP, hereby grants unto HELEN B. NELSEN, a single person, a non - exclusive easement for ingress and egress to and from the aforedescribed "Nelsen" property, over and upon the existing hard surface area (driveway) lying immediately south of the existing curbing, along the Northern boundary of the "Nendel's" property, a distance of Five Hundred Ninety Eight (598) feet, more or less. The easement hereby granted is thirty (30) feet in width." (emphases added) Mr. Stanley Hsiao, attorney representing Best Western - Southcenter, indicated in his October 7, 1999 letter that there are several problems with the easement. 1) The existing hard surface and existing curbing are not straight lines. Therefore, the easement as described can not be used as intended. See sketch attached to Mr. Hsiao's letter. Ms. Alexa Below Best Western Annex 11/30/99 Page 6 2) The easement was described as Tying immediately south of the existing curbing. Even if the existing curbing were straight lines, the easement would be only 10 feet where the property line jogged. 3) The easement as described did not reflect the driveway as it was located. 4) Exhibit A (dated October 16, 1991) cited in Mr. David Weitl's letter does not have any King County Auditor's File number. A copy of the Exhibit A as recorded would be the proper document to consider. And a copy of survey dated December 21, 1992 showing easement area was obviously prepared a year after the easement document was recorded on November 26, 1991. Please note the recording date on the upper right hand corner of the document. 5) Said easement does not cover additional property Nelsen wanted to access through the easement. 6) Logical solution —We suggest the easement description be corrected to reflect the actual location of the driveway as intended and the addition of more property be negotiated between the parties. We therefore conclude that the easement, as written, would not work for the Nelsens. We anticipate that these issues will have to be resolved through future negotiations. Parking 1) Traffic Demand Analysis The analysis, prepared by Garry Struthers Associates, Inc. indicated the following facts and estimates: a. Existing parking -350 stalls serves a 145 -room hotel, a full service restaurant, banquet and meeting facilities. b. Surplus parking —A maximum daily demand of 141 stalls were observed. A 209 -stall surplus now exists. 4-' • • w :mQQ : :J C) • :U O` N 0 W I J H.

Projected Daily Demand —An average daily demand of 179 stalls was estimated for the existing facilities plus the new Annex of 72 guestrooms. e. Projected Maximum Daily Demand — Maximum daily demand for the existing facilities and the new Annex of 72 guest rooms is estimated to be 210 stalls. This maximum daily demand will only occur sparsely during peak seasons. 2) Proposed Parking facility a. Assume easement issue was resolved -232 stalls including 33 within the disputed easement area. b. Assume easement issue were not resolved: a) Assume Nelsen's arguments prevail —In the unlikely event that Nelsen's arguments prevail, the south edge of the easement area could be rearranged to provide 12 additional stalls with total of 211 stalls, one over the maximum daily demand of 210. b) Assume no rearrangements of parking —A total of 199 stalls, 20 stalls over the average daily demand of 179, are available. And 33 stalls in the easement area can be utilized during the rare maximum demand days. After all, without resolution of the easement issue, Best Western is still the fee owner of the easement area and is entitled to the use of the property as long as the use do not interfere with the use of the easement by the Nelsens. z w J V; 0 0 ( o° • wI J N LL: 'W 0; LL a; •= a. :t-w. ?�: • i-0 .z t-, .0 0; • wW H U; • LL -z ui N. • 0 H O z Ms. Alexa Below Best Western Annex 11/30/99 Page 8 3) Loading space —Two loading spaces, required for the total 117,802 sq -ft of gross floor area, are provided at the south end of the restaurant. 4) Bicycle parking —Five stalls, while four stalls are required for the 199 car stalls, are provided at the southwest corner of the Annex. 6� O C.

[: OCT 2 5 1999 --J I represent Mr. Shute -Wen Liu, the owner of the above Best Western Motel. Mr. De -En Lang, the project manager of the Best Western Motel Addition Project, at your request asked me to write this letter to you regarding the letter of Mr. David Weitl of Northwest Realty Advisers, Inc. dated August 17, 1999, and to explain to you our understanding and interpretation of the easement raised by Mr. Weitl. The easement creating document (under K/C recording no. 9111260669) clearly describes the easement as that certain portion of the hard surface area, which is 30 feet in width `lying immediately south of the existing curbing, along the northern boundary of the "Nendel's" property'. Based on this clearly understood language, I had drawn the easement area on the enclosed map. The document was prepared by Nelsen's own counsel. The curbing existing today is the same as the curbing shown in the architect's original site plan. No one has changed, nor is there any reason to change, the curbing since it was built in or about 1986. T'ne easement created by that documents is virtually useless. The easement was actually never used. It was one of the reasons Mr. Liu was willing to accept Nelsen's proposal to straighten the easement when approached by Mr. Weitl in 1997, so that Nelsen could at least enjoy it. Please see the delineation of the easement in the attached map marked Exhibit "A ". Even if we would base on Nelsen's interpretation, namely, ignoring the meridians (or the curbed protruding-landscaping areas), the easement would still serve little purpose because both the boundary and the curbing turn north at 90° angle for 20 feet, then turn west at 90° angle again. Anyone can easily understand that the turn point leaves only Ten (10) feet for the vehicles to pass through, which is unacceptable by any standard. In addition, the 20 feet access as created by the document is also unacceptable for any RECEIVED development purpose. DEC 01 1999 1 EVELO COMMUNITY • .r...ti w..�.'r:%':n,+.i. ;:sY.tifnC:xr�•v.�..

Among others, Mr. Weitl wanted to add a new big parcel and other land to be acquired by Nelsen in the dominant estate of said easement. See Exhibit `B" Nelsen Property, the dominant estate as proposed by Mr. Weitl at that time, and Exhibit "C" showing the additional parcel Nelsen intended to benefit from the easement. After some negotiation with Mr. Weitl and Nelsen's attorney, the parties failed to reach agreement on all the terms.

Contingency Plan in Case of River Bank Failure Best Western Southcenter, 15901 West Valley Road Tukwila, Washington S&EE Job No. 9828C Per your request, we have reviewed our file and prepared this letter to outline the contingency plan in the event of river bank failure. This letter is prepared in reference to our letter report " Evaluation of River Bank Stability", dated May 3, 1999. We recommend that the following procedures be adopted in the contingency plan: 1. The hotel maintenance crew should prepare the followings: • A list of earthwork contractors that are experienced in levee or dike repair. • A list of shoring contractors that can react to emergency events that require installation of steel sheet piles of up to 50 feet in depth. • A list of material suppliers that can supply fill materials including sand, gravel. and quarry rock. Ltr092799 ECEIVED DEC 01 1999 COMMUNITY DEVELOPMENT S&EE De -En Lang September 27, 1999 Page 2 2. The hotel maintenance crew should inspect the river bank during and after, any sever rainstorm. If any sloughing, slide, or failure along the river bank is observed, the hotel manager should be notified immediately. 3. For any failure that results in a loss of 5 horizontal feet or more of the river bank, the situation should be evaluated by a qualified geotechnical engineer. The engineer should assess the risk of further ground loss, impact to the fire lane and hotel building, and recommend stabilization measures. For any bank failure that results in an immediate threat to the fire lane and building, the fire department and geotechnical engineer should be notified immediately. Depending on the situation, the earthwork and shoring contractors may need to be mobilized at once for installation of temporary shoring and dike stabilization measures. If the fire lane is dedicated to the city in the future, other pertinent authorities such as Parks Department should also be informed. Please note that continuous maintenance of the river bank is desired and the maintenance measures may include placement of rip rap at the toe of the bank. It is our opinion that rip rap is not required at this time, but its need should be evaluated on an annual basis by a geotechnical engineer. * * * We trust that this letter will serve the present needs.

Locate commerciaVdevelopment in areas with low potential for recreation or other public uses. 3. Preference should be given to commerciaVindustrial development that will provide an opportunity for a substantial number of people to enjoy the shoreline. SSDPMT.DOC 7/3/'96 6 4. Determine and consider the visual impact that the commerciaUndustrial development will have on the surrounding area. 5. Encourage provisions for public access, especially visual and pedestrian, as an integral part of commerciaUndustrial waterfront development. 6. Design new commerciaUndustrial facilities and improve existing ones in such a way as to minimize wasteful use of the shoreline. 7. Encourage multiple use types of commerciaUndustrial development to provide public access and promote round - the -clock utilization of the shorelines. 8. Short-term economic gain or convenience in developments should be evaluated in relation to long -term and potential impairments to the desirable biological features of the river and its shoreline. B. PUBLIC ACCESS ELEMENT 1. Public access to and along the water's edge should be provided in new developments. a. Water- dependent economic activities should be designed to allow substantial public access to the shoreline. 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. c. For multi - family residential developments, the water's edge should be kept free of buildings and fences with public access made possible. d. For a new single - family dwelling unit, the water's edge should be kept free of buildings and fences. e. For other non - specified development, the water's edge should be available for public access. f. All public shorelands, except as noted in other policies, should be available for public access to the water's edge. 2. Any modifications or extensions to existing development should be designed to allow public access. 3. A trail system should be developed along the river. a. Trails should be developed for linear access through public shoreline areas. b. Access points to and along the river should be linked by a system of trails. c. The connection of other trails in the region to the shoreline trail system should be encouraged and developed. d. To assist in developing a trail system, incentives should be offered to property owners for utilizing set -back areas. C. CIRCULATION ELEMENT 1.

Parking facilities should be located upland with provisions for adding pedestrian access to the shoreline. 3. Public transportation should be designated to facilitate access to and along the shoreline. 4. Railroads should be encouraged to offer their rights -of -way for multiple use consistent with a shoreline location and with public safety. D. RECREATIONAL ELEMENT 1. Publicly owned recreational uses should be enhanced and, when feasible, enlarged. SSDPMT.DOC 7/3/96 7 a. The public sh.,uld have first option to buy shoreland „s it becomes available for sale, based on an acquisition plan with dear public intent. b. The opportunity for sport fishing in the river should be enhanced. 2. Recreational uses should be incorporated with other shoreline activities. 3. Those unique or fragile areas of the shoreline which cannot be maintained in a natural condition under human uses should be designed and maintained as open space for passive forms of recreation. 4. Views of the shoreline and water from shoreline and upland areas should be preserved and , enhanced. w a. New shoreline development should not significantly obstruct views of the shoreline or 6 t o he water. o 0 0 b. Enhancement of views shall not be construed to mean excessive removal of vegetation. w =. E. SHORELINE USE ELEMENT WO 1.

Aesthetic considerations should be encouraged when contemplating a new development, redevelopment of existing facilities or for general enhancement of shoreline areas. 4. Planning, zoning, capital improvements and other policy and regulatory standards should not tend to increase the density or intensity of activities on the shoreline. F. CONSERVATION ELEMENT 1. Determine and consider the visual impact a commerciaVindustrial development will have on the surrounding area. 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 run -off, maintain constant water temperature and reduce siltation. 3. Promote linear shoreline access, especially pedestrian and other non - motorized types, in the areas close to population centers; such areas would also serve as buffer between water and developed areas. 4. Develop regulations for site coverage, building height, set -backs and density to insure visual access to water, promote interesting development and prevent encroachment over water. 5. Provide facilities for intensive recreational activities where the sewage disposal and vector control can be accomplished to meet public health standards without adversely altering the natural features attractive for recreational uses.

We understand that this stability evaluation is a part of the requirement for the proposed construction of a hotel annex. S &EE has conducted a geotechnical investigation for this hotel annex. Our report is dated October 14, 1998, a copy of which has been submitted to you previously. Previous geotechnical investigations at the project site were performed by Shannon and Wilson, Inc. (1973 and 1982) and. Earth Consultants, Inc. (1985). Many deep soil test borings were performed onsite, including one boring by us in 1998 during the study of the proposed hotel annex. Information obtained from these borings can be found in our October 14, 1998 report. 9828C rs,:i::a,.t:.J:..x:: RECEIVED JUN 3 01999 DEVVELOPMENT S&EE Mr. De -En Lang May 3, 1999 Page 2 During the course of our current study, we have consulted with Mr. Gary Barnet of City of Tukwila and Mr. Andy Leveque of King County Water And Land Resource Division regarding the requirements of the river bank evaluation. We have also reviewed the report of a similar study which evaluated the stability of 4 river banks along the Green River. This report is titled "Slope Stability Analysis of Four Green River Bank Stabilization Repair Projects, King County, Washington ", dated January 26, 1999 and prepared by Shannon & Wilson. One of the river bank evaluated located within 2 miles from the Best Western Southcenter site. Shannon & Wilson's report details the criteria used for the evaluation of river bank stability along Green River. In general, our analyses follow the same criteria stated in the report. Since the existing hotel building is situated near the river bank, we have evaluated the stability of the river bank itself and the impact of any potential river bank instability on the exiting building. Details of our analyses are presented in the later section of this report. A topographic survey was performed for the purpose of our evaluation. A copy of this survey is included at the end of this report. We performed our analyses along five cross - sections (lines AA through EE on the survey plan). These cross - sections cut through the north bank of Green River at locations where we believe are most critical in terms of river bank instability. SURFACE CONDITIONS At the location of the subject property, the north bank of the river rises at angles ranging from approximately 18 to 34 degrees. This bank rises about 29 to 34 feet from the toe to the top of the bank. An asphalt -paved fire lane borders the top of the bank. This lane runs east -west and is about 20 feet in width. North of the fire lane is a landscaping area containing grass, shrubs and trees. The Best Western hotel building is present directly north of the landscaping area. The distance from the edge of the building to the top of the river bank is about 35 to 60 feet. We understand from the hotel owner that the fire lane and river bank have been at their current conditions since his operation of the hotel 4 years ago. 9828C S &EE } 1S_; Mr. De -En Lang May 3, 1999 Page 3 The Best Western Hotel is a three -story, wood -framed building. There are two basements present under the building. One of these basements is located beneath the restaurant, at the east end of the building. The other is located near the western end of the building. We understand that the building is supported by conventional spread footings. Currently, the river bank is heavily vegetated with vines and brushes. A few mature tress are also present above the water line. We observed signs of erosion near the water line and surface sloughing near the top of the bank. This sloughing has caused portions of the southern edge of the fire lane to crack. The sloughing appeared to be relatively shallow and only present at isolated locations. SUBSURFACE CONDITIONS As previously mentioned, many deep borings were performed at the site. The boring data indicate that the soil present in the upper portion of the soil profile consists of a loose, silty sand of approximately 10 to 15 feet in thickness (layer 1). This layer is underlain by a loose to medium dense sand, which is approximately 25 feet thick (layer 2). Underlying this layer are layers of medium dense to dense sands, soft to stiff silts, and dense gravels. These layers extend to great depths and their presence has little effect on the stability of the river bank. ENGINEERING ANALYSIS We performed slope stability analyses using the computer program STABL5. Our analyses investigated static state conditions for the river bank at its current condition and during a rapid river drawdown. We investigated the sliding surfaces that represent local and global failures. The former examines the failure potential and pattern of the river bank itself. The latter is deep- seated with potential failure surfaces extending from the river bank to the existing building. 9828C S &EE Z �Z ce .6D' .J U :O Oi ,tW 0' Ul cow; ;CO u.,; w g J u- Via.

This back - calculation is based on the understanding that the river bank has been stable for many years and shallow sloughing has occurred near the top of the bank. Based on these conditions and the soil profile, the representative soil parameters can be obtained by adjusting them until the result shows the occurrence of shallow sloughing with the deep- seated mode remaining stable. The strength parameters, so calculated, represent the effective stress or drained conditions. Results of this back - calculation are listed in the table below. TABLE 1 EFFECTIVE SOIL PARAMETERS Soil Friction Angle (degrees) Cohesion (psi) Layer 1 Consisting the upper 10 to 12 feet of the river bank 32 30 Layer 2 Consisting the lower portion of the river bank 35 30 Based on the soil boring information and our experience with the materials, we believe these parameters are reasonable. Our next step was to evaluate the stability of the river bank during a rapid drawdown. Rapid drawdown represents a situation in which the river level rises to the top of the river bank and then is drawn down in a relatively short period of time. Due to this short time period, the soils up -slope of the river level are not fully drained and thus a positive hydraulic head in the river bank is created. Typically, rapid drawdown is considered to be a worst case scenario in terms of river bank stability. We understand that flows within the Green River are mainly controlled by the Corps of Engineers, who regulates discharge from Howard Hanson Dam. We further understand from Mr. Andy Leveque that the maximum allowable drawdown at 9828C S &EE telemstottaxtatorteift .= z z.

The Shannon & Wilson's report indicates that the more realistic drawdown rate is I to 2 feet per day. This rate would allow partial dissipation of pore water pressure in the river bank and thus reduction in the potential of instability. However, we followed Mr. Leveque's suggestion to use a conservative approach. that is, no dissipation of pore water pressure is assumed in our analyses. Undrained shear strengths or total stress parameters were used for the case of rapid drawdown. Based on the drained shear strength presented in Table 1 and our experience with the materials, we have estimated the following undrained parameters: TABLE 2 TOTAL STRESS PARAMETERS Soil Friction Angle (degrees) Cohesion (psl) Layer 1 26 100 Layer 2 28 100 The results of our analyses indicate that during a rapid drawdown, the bank will have factors of safety ranging from 0.8 to 1.1 for the local/shallow failure mode and 1.3 to 1.6 for the deep- seated failure mode. The factor of safety is defined as the summation of resisting forces divided by the summation of driving forces. The standard engineering practice considers a slope to be acceptably stable if it demonstrates a factor of safety of around 1.4 to 1.5 or above and the slope is considered to be unstable if the factor of safety is below 1.0. The above results indicate that during rapid drawdown, the river bank will likely suffer shallow failure. However, the deep- seated failure which would impact the stability of the building, will be unlikely. Further examination on the failure surface indicates that the shallow failure is limited to within 5 to 10 feet from the surface of the bank. This failure surface will likely effect the fire lane located to the north of the river bank. 9828C w......,.,.,.s .

U -'. • Mr. De -En Lang May 3, 1999 Page 6 CONCLUSIONS AND RECOMMENDATIONS Based on our observations and analyses, it is our opinion that the river bank adjacent to the property is relatively stable. However, erosion at the lower portion of the bank especially below vegetation is likely to continue. This erosion will result in surface sloughing, which under the average river level, will be about a few feet in depth. This type of sloughing will most likely continue to cause the pavement at the southern edge of the fire lane to slough and crack. The erosion at the lower portion of the river bank and sloughing near the top of a river bank is very typical and will require continuous maintenance. Such maintenance may include placement of rip rap at the toe of the slope for erosion protection. It is our opinion that the protection is not required at this time but may be needed in a few years or after a few major storm events. For the scenario of future rapid drawdown, surface sloughing as deep as 5 to 10 feet will likely occur. The sloughing will damage the southern 5 to 10 feet of the fire lane. As the distance from the top of the bank to the existing building is at least 35 feet, we believe that repair of the fire lane can be performed from the future top of the bank. We envision that the repair will involve a toe buttress and soil fill. Our analyses indicate that the deep- seated failure which would extend from the toe of the bank to the building is unlikely. However, the shallow sloughing stated above may trigger a progressive failure toward the building. If un- prevented, such progressive failure may eventually undermine the building foundation. The progressive failure can occur in a relatively short period of time especially if the river level fluctuates at the time. We believe that the reaction time to such a potential problem may only be a few days. Since re- building of the river bank may not be possible in such short period time, we recommend that a contingency plan for such a scenario be prepared. The purpose of this plan is to prevent the northward progression of sloughing from undermining the building foundation. We envision that the plan may include a temporary shoring system such a sheet pile wall installed near the building line. Details of this wall will depend on the actual conditions and should be evaluated prior to the wall installation. 9828C S &EE .Z z re §r.
