Rants, Mayor Department of Community Development Steve Lancaster, Director Mr. Stephen G. Moluse The Richard E. Jacobs Group, Inc. 25425 Center Ridge Road Westlake, OH 44145 RE: File L99 -0016 (Southcenter Mall South Entrance). Dear Mr. Moluse: The potential environmental impacts of your proposed 5,000 square foot new commercial area within the existing envelope of a 1.7+ million square foot shopping mall, have been evaluated based on the "Elements of the Environment" identified in WAC 197 -11 -960. This environmental analysis was based on cumulative project impacts of the new 5,000 s.f. addition and a previous 111,032 s.f. addition to the mall in 1991. A mitigated determination of non - significance was issued for the 1991 addition (Tukwila file no. EPIC - 11.91). Adding an additional 5,000 s.f. to the previous 111,032 s.f. action "...adds analyses or information about a proposal but does not substantially change the analysis of significant impacts and alternatives in the existing environmental document." (WAC 197- 11- 600(4)(c)). It is thus appropriate to satisfy the required SEPA environmental review for the new 5,000 s.f. commercial area using the existing environmental document, through the "addendum" process specified in WAC 197- 11- 600(4)(c) and 625. The existing mitigated determination of non - significance for the "Southcenter Mall Addition ", Tukwila file no. EPIC- 11 -91, is herewith amended to include the new 5,000 s.f. commercial addition to the Southcenter Mall. Please contact me if you have any questions or if I may be of further help.

DESCRIPTION OF PROPOSAL The proposal involves a 111,032 square foot expansion to the Southcenter Shopping Center. The addition would include a 86,150 square foot department store ( Mervyn's) and 24,882 square feet of mall shops. The mall expansion would be located on the northeast corner of the existing shopping center. The project would also include re- stripping the existing parking lot to add 206 parking • • Page 3 EPIC -11 -91 spaces and additional landscaping. Perimeter and interior pedestrian access would be provided along streets and to the expansion area. See the Public Improvements discussion below. PERMITS REQUIRED - Design Review - Grading Permit - Building Permit - Street use /Utility permits DESIGN FEATURES Mall Expansion. The 24,882 square foot mall addition would be located directly north of J.C. Penny's. Three hundred forty eight parking stalls would be replaced with the expansion. The project involves extending the mall by approximately 200 linear feet from the J.C. Penny's department store northward. A new mall entrance would be located immediately north the J.C. Penny building. The design would be similar to the Rainier Food Court entry. The lower half of the 25 -foot height wall would be recessed by approximately six feet. Trees and tree grates would be installed adjacent to the walkway linking the new mall entrance to the Mervyn's entrance. The building skin would be a red -tone brick with contrasting color bands similar to Nordstrom and the entrance on the mall's south elevation. Mervyn's would total 82,940 square feet in area with entrances on the north, west and east sides. (See the site plan attached.) Additional landscaping is proposed for the parking areas north, east and south of the existing mall and expansion areas. Landscaping would be installed along the mall shops expansion area and within the existing and parking areas. Additional landscaping would be provided along street frontages. Proposed landscaping would be reviewed by the Board of Architectural Review during the Design Review process. CHECKLIST ITEMS A. EARTH The site is relatively flat and is occupied by a regional shopping mall. A geotechnical report was prepared for this project by Shannon & Wilson, Inc. dated November 1988. The site is underlain by soft compressible material. The potential for additional settlement could occur from 2 to 6 inches over a majority of the site during the next 10 to 15 years as result of fill placed on the site in the early 1960's. See Condition NO's 1 and 2. Page 4 EPIC -11 -91 B. WATER The site is currently occupied with development and is not in the vicinity of a water body. The proposal will not result in soil erosion or siltation. No additional impermeable surface area would be created with this project. C. LANDSCAPING A majority of the site not occupied by existing structures is paved parking area. Perimeter landscaping exists adjacent to streets surrounding the site. Landscaped strips extend along entrance aisles into the shopping mall. The existing landscaping does not conform to Section 18.52.020 of the Tukwila Municipal Code. Additional landscaping is proposed with this project. The Board of Architectural Review would review issues pertaining to existing non - conforming landscaping, and proposed landscaping as part of the Design Review process. D. AESTHETICS The Board of Architectural Review (BAR) shall review the design of the proposed Southcenter mall expansion and Mervyn's Department Store in accordance with the five adopted design criteria. E. NOISE Compliance to TMC 8.22.160 will be required to mitigate temporary construction noise impacts. F. TRANSPORTATION A traffic impact analysis dated April 19, 1991 prepared TRANSPO was submitted to the City. The study identified existing conditions of public improvements and numbers of additional trips generated with the proposed mall expansion project. The study concluded that the project would result in impacts to the transportation network. In order to reduce impacts to traffic and improve the existing network and levels of service, the applicant, the City of Tukwila and METRO Transit have agreed to a variety of proposed mitigation measures. The proposed conditions are attached and include the following: 1. Re -route transit facilities now located within the mall parking area to Andover Park West. 2. Install traffic signal at the Andover Park West /Baker Blvd. intersection. • • Page 5 EPIC -11 -91 3. Grant easements for transit stops /access 4. Dedicate right -of -way for transit access. 5. Provide sidewalks along Andover Park West and Strander Blvd. 6. Provide additional public improvements along Andover Park West. Exhibit "A" specifies the location and proportionate share of costs to be paid by the applicant for public improvements. The proposed public improvements would mitigate impacts related to the proposed project and would be conditions required as part of the SEPA determination. In conjunction with the mitigation measures proposed by the applicant, the City would provide all necessary rights -of -way and easements on the east side of Andover Park West required for the signal installation and the northbound bus pull -out. The City would also provide construction inspections free of charge and would order and pay up -front costs for the signal controller for the Andover Park West /Baker Blvd. intersection. The City would be reimbursed for the cost of the controller. G. UTILITIES It has been determined that the water supply is adequate for the proposed addition to the Southcenter Mall site. A test for water flow and pressure was conducted on April 30, 1991. The test revealed that water pressure and flow in the vicinity of Southcenter Mall would be adequate to provide fire protection for the proposed shopping center expansion. It was also determined that the existing 8 -inch water main along Andover Park West provides inadequate flow velocities that exceed the current 10 feet - per - second (fps) design criteria. This conclusion is based upon Tukwila's Water Comprehensive Plan. CONCLUSIONS AND CONDITIONS Issuance of a Mitigated Determination of Non - Significance is appropriate for the proposed Southcenter Shopping Center expansion project (EPIC- 11 -91) because the required mitigation measures required as project conditions would reduce potentially adverse environmental impacts below a level of significance. Page 6 EPIC -11 -91 Conditions would be as follows: EARTH CONDITION 1 a. Proposed grading should include export fill for structural support pursuant to the recommendations of the geotechnical report dated November 1988. b. Foundation design should include pile supports for the mall shops addition prior to issuance of building permits, the Building Department shall ensure the foundation plan is designed for the geologic conditions of the site as discussed in the geotechnical report dated November 1988. BUS STOP /TRANSPORTATION CONDITION 2 The existing bus stop located within the mall parking lot would be relocated to Andover ParkWest. This joint project between Jacobs, Visconsi & Jacobs, Metro, and the City of Tukwila is intended to relieve Metro's operational inefficiencies in operating through the mall parking facility and to eliminate further routing modifications necessitated by the mall expansion. DIVISION OF RESPONSIBILITIES CONDITION 3 Jacobs, Visconsi & Jacobs a. Jacobs, Visconsi & Jacobs will coordinate and administer the design and construction of the north bound and south bound pull -outs. Actual construction costs to be reimbursed by Metro. However, cost for engineering design and construction administration will be funded by Jacobs, Visconsi, & Jacobs. b. Dedicate the necessary right -of -way to the City of Tukwila for the pavement, curb and gutter portions of the south bound pull -out. c. Provide easements for sidewalk and bus shelter footings located at the south bound pull -out on the west side of Andover Park West. d. Coordinate the design and construction of the Andover Park /Baker Boulevard traffic signal.

The stairway design would be reviewed and approved by the Department of Public Works. CONDITION 4 CONSTRUCTION OF ANDOVER PARK WEST SIDEWALKS a. Jacobs, Visconsi & Jacobs would design and install a 5' wide sidewalk with a 2' wide paved vehicular overhang area along Andover Park West in accordance with Site Plan L -1, dated 4/19/91, and sketch SK -3 dated 3/21/91. Existing parking adjacent to Andover Park West will be modified for use by compact cars to minimize impact on existing landscape. b. New sidewalks will not be installed at the Firestone or Union 76 parcels due to site area Page 8 EPIC -11 -91 restrictions. Continuous pedestrian circulation is currently provided at these locations across paved access drives. CONDITION 5 CONSTRUCTION OF STRANDER BLVD. SIDEWALKS a. Jacobs, Visconsi & Jacobs will design and install a 5' wide sidewalk along Strander blvd. in accordance with Site Plan L -1, dated 4/19/91, and Sketch SK -3 dated 3/21/91. Existing parking adjacent to Andover Park West will be modified for use by compact cars to minimize impact on existing landscape. b. Jacobs, Visconsi & Jacobs will design and install a 4' wide sidewalk /stairway connection from the intersection of Strander and Southcenter Parkway to the south west corner of the Doubletree parking lot. The City of Tukwila will not require sidewalks along the south side of the Doubletree Parcel due to topographic constraints and the negative impact on existing parking. See Dwg. L -1, dated 4/19/91. Pedestrian access would be provided through the Doubletree site onto the new sidewalk to be installed by the applicant. Existing sidewalks will not be modified along Tukwila Parkway or Southcenter Parkway. It has been determined by the Tukwila Planning and Public Works Departments that existing sidewalks in place satisfy the requirements of the City's sidewalk ordinance. c. Jacobs, Visconsi & Jacobs will design and install a pedestrian connection from the relocated bus pull- out to the mall, as shown on Dwg. L -1, dated 4/19/91. d.

Jacobs, Visconsi & Jacobs will reconstruct the existing pedestrian stairway on Tukwila Parkway to align it with the Bon's east sidewalk, as shown on Dwg. L -1, dated 4/19/91. Page 9 EPIC -11 -91 g. CONDITION 6 Jacobs, Visconsi & Jacobs will modify post office access to improve traffic flow along Andover Park West, as shown on Dwg. L -1, dated 4/19/91. Jacobs, Visconsi & Jacobs will modify internal parking configuration and traffic circulation to improve traffic flow and reduce congestion on the surrounding road network by reducing congestion at existing four -way intersections. CONDITION 7 Jacobs, Visconsi & Jacobs will pay a pro -rated share of the following traffic improvements, based on the percentages and establish construction costs listed on the attached Exhibit A: a. Andover Park West: curbing on the west side of the street right -of -way. b. Southcenter Parkway and Strander Blvd. intersection sidewalk improvements. c. Andover Park improvements. d. Andover Park West signal control. West /Strander intersection and Tukwila Parkway traffic Jacobs, Visconsi & Jacobs agrees to reimburse the City the proportionate cost of the above improvements, up to the per improvement percentage and dollar amount limits set forth in the attached Exhibit A upon completion of each improvement. CONDITION 8 UTILITIES A no- protest agreement to upgrade the waterline would be required. The comprehensive plan has identified the replacement of the existing as necessary; the deficiency is where flows have been exceeded the 10 fps standard (20 fps for fire flow). Resulting water hammer causes PR valves to fail(no PR by Southcenter flanges). The '. development will further increase the flow velocity. An LID for this improvement and no- protest would provide the corrective action. EXHIBIT A Jacobs, Visconsi & Jacobs proportionate share contributions for public improvements to be constructed by the City of Tukwila: $10,400 a. Andover Park West (Tukwila Parkway /Strander Blvd) (excepting Baker improvements by JVJ) The street will be widened to provide for vehicle left turns. There's an existing left turn safety and capacity problem, the additional left turn volume will range from 220 /day on the north to 490 on the south. This additional traffic will exacerbate the left turn safety and capacity. Widening is being designed. JVJ's share is being quantified as the cost of the curb to be replaced on their frontage, approximately 1,300 feet @ $8 /ft. is $10,400. $12,300 b. Southcenter Parkway / Strander LOS. To raise the LOS and pedestrian safety, the east leg will be widened and a sidewalk constructed on the south side. JVJ's share based on increased per hour volumes: 186 growth for 5 years 150 other known development 30 JVJ 366 total 30/366 = 8.2% 8.2% of $150,000 = $12,300 $22,400 c. Stander /Andover Park West Widening for north /south left turn lanes and signal control 149 growth for 5 years 163 other development 90 JVJ 402 total 90/402 = 22.4% 22.5 of $100,000 = $22,400 $10,540 d. Tukwila Parkway /Andover Park East signal control 66 growth for 5 years 75 other known development 20 JVJ 161 Total 20/161 = 12.4% 12.4% of $85,000 = $10,540 North S 159TH ST Bank • S 159TH ST PROPOSED EXPANSION EXISTING SOUTHCENTER MALL CITY OF TUKWILA DEPARTMENT OF COMMUNITY DEVELOPMENT ENVIROWENTAL REVIEW ROUIING FORM EPIC: tit ' IIIOJEC12:203c..102402..,_1(hsu____Eaaor22is ADDRESS DATE TRANSMITTED a .

RE: Southcenter Shopping Center SEPA Draft Declaration of Non - Significance Dear Jack: Thank you for giving us the opportunity to comment on the May 29, 1991, draft SEPA Declaration of Non - Significance. Our suggested modifications to the SEPA determination have been marked on the attached copy of your draft document and have also been summarized below. Although the majority of our comments are minor in nature, I believe that there are three (3) items which deserve some additional comment and discussion. 1. Page 4, Paragraph C, Landscaping The existing landscaping at Southcenter Mall was designed and installed in compliance with zoning regulations in effect when the mall was originally constructed. Additional landscaping is now being proposed for areas of the existing parking lot which are being modified to support the Mervyn's Expansion. New landscaping in these areas will conform to Section 18.52.020 of the Tukwila Municipal Code and, therefore, it seems appropriate that references to nonconforming landscape in areas which are not being modified by this project be deleted from the SEPA comments. 2. Page 4, Paragraph F, Transportation The traffic impact analysis, dated 4/19/91, prepared by Transpo evaluating the impact of this expansion concludes that "the proposed expansion project will not significantly impact traffic operations or safety in the vicinity of the shopping center." (Page 56, Paragraph 1.) The SEPA comment in Paragraph F, Sentence 3, should be modified to correctly state the conclusion presented in the Transpo report. • • Mr. Jack Pace May 30, 1991 Page 2 3. Page 5, Paragraph G, Utilities Extensive evidence has been provided to the City of Tukwila which indicates that the water pressure and flow in the vicinity of Southcenter Mall will be adequate to provide fire protection for the expanded shopping center in accordance with the City's comprehensive water plan requirements. The addition of new mall shops and the Mervyn's Department Store will not increase the fire flow requirements since sprinkler demand is based on the largest loss or highest risk. (The demand is not additive.) Since the flow requirements from any one of the existing department stores exceeds the demand for the proposed Mervyn's or mall shop expansion, there will not be any additional fire flow demand on the system, therefore, this expansion will have no impact on the City of Tukwila's water supply. Attached is an analysis prepared by Stecklow & Associates which was previously submitted to the City of Tukwila in April, 1991, along with copies of recent water flow /pressure tests which were obtained by the City of Tukwila. The results of the test data shows that flows and pressures exceed the requirement of 2,000 gpm at 30 psi for retail development as required by the City's comprehensive water plan. It is has been shown that the proposed mall expansion will not impact the City's water supply system, therefore, all references to the need to upgrade the existing 8" water line in Andover Park should be removed from the SEPA determination. Additionally, Condition 8 on Page 8, Utilities, should be deleted. The following minor modifications and corrections should also be considered. Page 1, Location: Substitute Northwest for Southwest Page 3, Paragraph 1: Substitute the word "lower" in lieu of the word "upper." Paragraph 1: Substitute "tree grates" in lieu of "planter boxes." Paragraph 1: Delete the words "and benches." Page 4, Paragraph 4, F. Transportation Delete last sentence. Substitute the following language from Page 56 of the Transpo Traffic Study. The study concludes that "The proposed expansion project will not significantly impact traffic operations or safety." Paragraph 5, Line 4, Delete "and future road widening." No R.O.W. will be required for road widening of Andover Park West. • • Mr. Jack Pace May 30, 1991 Page 3 Page 5, Item G Delete text reference to capacity of existing 8" water line. Replace with: Evidence has been submitted which shows that water pressure and flow in the vicinity of Southcenter Mall is adequate to provide fire protection for the expanded shopping center in accordance with the City's comprehensive water plan. The addition of mall shops and the Mervyn's Department Store will not increase the fire flow requirements (fire flow requirements are based on highest risk), therefore, there is no impact on the City of Tukwila's water supply system. Page 6, Item G, Delete - (This segment of sidewalk exists.) Item L, Replace the words Southcenter parking lot with Double Tree parking lot. Page 8, Condition 7 Coordinate with items A through D on Exhibit 'A' a) Andover Park West (Tukwila /Strander) west side curbing. b) Southcenter Parkway at Strander intersection improvement. c) Strander at Andover Park West intersection improvement. d) Tukwila Parkway at Andover Park West signal control. Condition 8 Delete Jack, I believe we have made significant progress in determining equitable mitigation measures to compensate for the minimal impact this project will have on the City of Tukwila and look forward to finalizing the SEPA determination and moving forward with the Board of Architectural Review process. Please feel free to call me with any questions, comments, or clarifications you may require regarding our comments on your draft report.

My comments are limited to the Conditions Section on pages five and six, which refers to the "Division Of Responsibilities" for the bus stop relocation. In the SEPA Application "List Of Proposed Mitigation Items" dated April 26th, the specific responsibilities on the part of JVJ, Metro, and the City of Tukwila were clearly identified. To clarify the division of responsibilities, I'd suggest that the items listed in Condition 3 on . pages five and six of the draft DNS be grouped according to the entity responsible for carrying them out. Metro's items are J and K. Please add two items for which the City of Tukwila is also responsible. These would be for informational purposes only, but would help to clarify the involvement of JVJ, Metro and Tukwila in the overall project. From the April 26th SEPA Application they are: 1. City will provide all necessary. R.O.W. and easements on the east side of Andover Park West required for the signal installation and the northbound bus pullout. 2. City will provide construction inspection free of charge and will order signal controller. Cost of signal controller to be reimbursed by Metro.

Proposed landscaping will be reviewed by the Board of Architectural Review during the Design Review process. CHECKLIST ITEMS A. EARTH The site is relatively flat and is occupied by a regional shopping mall. A geotechnical report was prepared for this project by Shannon & Wilson, Inc. dated November 1988. The site is underlain by soft compressible material. The potential for additional settlement could occur from 2 to 6 inches over a majority of the site during the next 10 to 15 years as result of fill, placed on the site in the early 1960's. See Condition NO's 1 and 2. B. WATER The .[alto is currently occupied with development and Ls not in the vicinity of a water body. The proposal will not result in soil erosion or siltation. No additional impermeable surface area would be created with this project. 05/31/91 .,99:55 ,.n'` Lab 892 3665 JVJ LEASING /ENG y »y TUK PUB WORKS al 008 TUK PUB P�ORKS ��,JVJ �L IS N ®005 [MAY 31 1991 C.

During our discussions with Public Works we expressed our belief that the Mervyn's/Mall Shop expansion would not increase the fire flow requirements since sprinkler demand is based on the largest loss or highest risk. In other words, the demand is not additive. Since the flow requirements from any one of the existing department stores exceeds the demand for the proposed Mervyn's or Mall Shop expansion, there will not be any additional fire flow demand on the system. The attached analysis prepared by Stecklow & Associates Company, PA with assistance from Factory Mutual Engineering (FM) supports our opinion that based on NFPA, Industrial Risk Insurers (IRI) and Factory Mutual requir+ments, there will be adequate water supply to provide fire sprinkler service at the property after the addition of Mervyn's and mall expansion. Additionally, the analysis demonstrates that the capacity of the existing water supply system far exceeds NFPA IRI and Factory Mutual standards as well as the City of Tukwila's own standards. The Tukwila comprehensive water plan states that a minimum of 2,000 GPM must be provided at a minimum residual pressure of 30 psi. The attached Factory Mutual test data indicates that a supply of 3,000 GPM is available to the project at a residual pressure of approximately 69 psi (see attached Factory Mutual correspondence and curve data). The above information clearly confirms that an adequate water supply for fire protection will be available at Southcenter Mall after the expansion to satisfy NFPA, Factory Mutual and the City of Tukwila's comprehensive plan requirements. 05/31/91 10:00 /2216 892 2712 Mr. Jack Pace April 30, 1991 Page 2 JVJ LEASING /ENG 444 TUK PUB WORKS 2016 Further, taking into consideration Public Works feeling that the site should be considered light industrial requiring a minimum flow of 3,000 gallons per minute at a 30 psi residual pressure, the available flow of 3,000 GPM at 69 psi from the existing 8" water line will satisfy that criteria as well.

Washington, 11 ty Water System Supply o Dear Steve; G We have reviewed the corresp ndence from the City, IRI and Ill Factory Mutual relative to t adequacy of the water supply for t the site. It is our opinion hat, per NFPA, per IRI and per Factory Mutual requirements, there will not be any additional water demand for fire /sprinkler service at the property with the addition of Mervyns since the demand on sprinkler systems are not 2 additive per building. The existing demand from either the • Frederick and Nelson, or from the Nordstrom, or from the Bon, or from J.C. Penneys, or from the Mall /Mall shops is as much as will be the demand from the proposed Mervyns store. The capability of the water supply system, per the flow tests z performed by IRI and previously by FM, indicate the public water e supply systems far exceeds not only the requirements of NFPA, i IRI, and FM but also that of the City of Tukwila as it relates to 8 capacity. The City of Tukwila's Comprehensive Water Plan states a that for a commercial area a minimum of 2000 gpm be provided at a minimum residual pressure of 30 psi. The correspondence from the Staff Report states consideration should given to considering the site light industrial, which would increase the minimum flow i requirement to 3000 with the 30psi residual minimum. Even though I do not believe a shopping center /department store is light I industrial, the current water supply system, with the 8" feed > mains on Andover Park West, exceeds these requirements. Per the FM test, a supply of 3000 gpm is available with a residual pressure of approximately 69 psi, as so rioted on the attached curve and FM correspondence. 2 W Z can understand the City's long term plan to provide minimum z feed main sizes, however, to require a replacement of a line which has capacity to exceed the City's own requirements does not seem appropriate. It would be logical, if the City wants to revise this line to a 10 ", the City should do so when the line requires replacement due to poor condition. Cordially, STECKLOW ND ASSOCIATES CO. P.A.

This will confirm various phone conversations regarding the available water supply to the subject mall. The closest factory Mutual water test to this site was run on Southcenter Parkway, just north of the Southcenter Mall. The test results were a static of 146 psi reducing to 110 psi with a flow of 2522 gpm. This test compares favorably to other tests in the area. Based on the topographic map you faxed me of the area around the mall, the site is relatively flat and elevation loss between the test site and the mall is of no significance. Adjusting the above test through the mall lead in from 57th Ave. and the 10 and 12 inch loop around this mall shows 3000 gpm at 69 psi should be available at the south corner of the loop near the TBA store. This Should be more than ample for fire protection purposes and exGeeds Factory Mutual requirements for retail facilities. If you have any questions or wish to discuss this further, please call.

The 24,882 square foot mall addition would be located directly north of J.C. Penny's. Three hundred forty eight parking stalls would be replaced with the expansion. The project involves extending the mall by approximately 200 linear feet from the J.C. Penny's department store northward. A new mall entrance would be located immediately north the J.C. Penny building. The design 1 would be similar to the Rainier Food Court entry. The r half of the 25 -foot height wall would be recessed by approximately six feet. Trees -^e __ = would be installed adjacent to the walkway linking the new mall entrance to the Mervyn's entrance. T e building skin would be a red -tone brick with contrasting similar to Nordstroms and the entrance on the mall's south elevation. Mervyn's would total 82,940 square feet in area with entrances on the north, west and east sides. (See the site plan attached.) Additional landscaping is proposed for the parking areas north, east and south of the existing mall and expansion areas. Landscaping would be installed along the mall shops expansion area and within the existing and parking areas. Additional landscaping - would be provided along street frontages. Proposed landscaping will be reviewed by the Board of Architectural Review during the Design Review process. CHECKLIST ITEMS A. EARTH The site is relatively flat and is occupied by a regional shopping mall. A geotechnical report was prepared for this project by Shannon & Wilson, Inc. dated November 1988. The site is underlain by soft compressible material. The potential for additional settlement could occur from 2 to 6 inches over a majority of the site during the next 10 to 15 years as result of fill placed on the site in the early 1960's. See Condition NO's 1 and 2. B. WATER The site is currently occupied with development and is not in the vicinity of a water body. The proposal will not result in soil erosion or siltation. No additional impermeable surface area would be created with this project. • • C. LANDSCAPING A majority of the site not occupied by existing structures is paved parking area. Perimeter landscaping exists adjacent to streets surrounding the site. Landscaped strips extend along entrance aisles into the shopping mall. The existing landscaping does not conform to Section 18.52.020 of the Tukwila Municipal Code. Additional landscaping is proposed with this project. The Board of Architectural Review would review issues pertaining to existing non - conforming landscaping, and proposed landscaping as part of the Design Review process. D. AESTHETICS The Board of Architectural Review (BAR) shall review the design of the proposed Southcenter mall expansion and Mervyn's Department Store in accordance with the five adopted design criteria. E. NOISE Compliance to TMC 8.22.160 will be required to mitigate temporary construction noise impacts. F. TRANSPORTATION A traffic impact analysis dated April 19, 1991 prepared TRANSPO was submitted to the City. The study identified existing conditions of public improvements and numbers of additional trips generated with the proposed mall expansion project. The study concluded that potential impacts to the existing transportation system could be significant. In order to reduce potential impacts to traffic and improve the existing transportation network, the applicant, the City of Tukwila and METRO Transit have agreed to a variety of proposed mitigation measures. The proposed conditions are attached and include the following: 1. Re -route transit facilities now located within the mall parking area. 2. Install traffic . signal at Andover Park West /Baker intersection. 3. Grant easements for transit stops /access p • Dedicate right -of -way for transit access and future road widening. 5. Provide sidewalks along Andover Park West and Strander Blvd. 6. Provide additional public improvements along Andover Park West. Exhibit "A" specifies the location and proportionate share of costs to be paid by the applicant for public improvements. The proposed public improvements would mitigate impacts related to the proposed project and would be conditions required as part of the'SEPA determination. MEV 'Sein441/i115 v _ Co c-r PS G. UTILITIES F-1 n 1 � � - d 5 n. G r 0., The existing 8 -inch water main along Andover Park West has been determined to be inadequate f-^� i -_ e startinn rr g This conclusion /s based upon Tukwila's Water Comprehensive Plan. CONCLUSIONS AND CONDITIONS Issuance of a Mitigated Determination of Non - Significance is appropriate for the proposed Southcenter Shopping Center expansion project (EPIC- 11 -91) because the required mitigation measures required as project conditions would reduce potentially adverse environmental impacts below a level of significance. Conditions would be as follows: EARTH CONDTION 1 a. Proposed grading should include export fill for structural support pursuant to the recommendations of the geotechnical report dated November 1988. .b. Foundation design should include pile supports for the mall shops addition prior to issuance of building permits, the Building Department shall ensure the foundation plan is design for the geologic conditions of the site as discussed in the geotechnical report dated November 1988. BUS STOP /TRANSPORTATION CONDITION 2 The existing bus stop located within the mall parking lot would be relocated to Andover Park West. This joint project between Jacobs, Visconsi & Jacobs, Metro, and the City of Tukwila is intended to relieve Metro's operational inefficiencies in operating through the mall parking facility and to eliminate further routing modifications necessitated by the mall expansion.

MEMORANDUM TO: Jack Pace, Senior Planner FROM: Ron Cameron, City Engineer 2 DATE: May 28, 1991 SUBJECT: Mervyn's Southcenter Expansion A substantial number of safety issues have been resolved (JVJ will construct) and this memo identifies "fair share" of others. The traffic "fair share" has been calculated using the Transpo study and waterline is a no- protest LID. 1. JVJ constructed mitigations: a. Stairway connecting Southcenter Parkway north of Strander to the Southcenter lot will provide for pedestrian traffic. The safety issue identified was for pedestrians walking along the north side of Strander. b. Andover Park West /Baker signal bus pullouts and crosswalks are being constructed to provide for left turns, pedestrians, and intersection traffic. Vehicle and pedestrian safety will be retained with these. c. Sidewalks along Andover Park West and along Strander are being constructed by JVJ to provide for pedestrian movement. d. Internal vehicle and pedestrian circulation improvements will provide safety and capacity for access to another site. 2. JVJ fair share that will be constructed by the City: $10,400 a. Andover Park West (Tukwila Parkway - Strander) (excepting Baker improvements by JVJ) The street will be widened to provide for vehicle left turns. There's an existing left turn safety and capacity problem, the additional left turn volume will range from 220 /day on the north to 490 on the south. This additional traffic will exacerbate the left turn safety and capacity. Widening is being designed. JVJ's share is being quantified as the cost of the curb to be replaced on their frontage, approximately 1,300 feet @ $8 /ft. is $10,400. MEMO TO: Jack Pace FR: Ron Cameron page two $12,300 b. $22,400 c. $10,540 d. e. RMC /cd Southcenter Parkway /Strander LOS. To raise the LOS and pedestrian safety, the east leg will be widened and a sidewalk constructed on the south side. JVJ's share based on increased per hour volumes: 186 growth for 5 years 150 other known developed 30 JVJ 366 total 30/366 = 8.2% 8.2% of $150,000 = $12,300 Strander /Andover Park West Widening for north /south left turn lanes and signal control 149 growth for 5 years 163 other developed 90 JVJ 402 total 90/402 = 22.4% 22.5 of $100,000 = $22,400 Tukwila Parkway /Andover Park East Signal control 66 growth for 5 years 75 other known development 20 JVJ 161 total 20/161 = 12.4% 12.4% of $85,000 = $10,540 Waterline LID A no- protest agreement to upgrade the waterline. The comp plan has identified it as needing to be replaced; the deficiency ss flows have intersected so that the 10 fps standard is exceeded (20 fps for fire flow) . Resulting water hammer causes PR valves to fail (no PR by Southcenter flanges). The development will further increase the flow velocity. An LID for this improvement and no- protest will provide the corrective actions. xc: file: Mervyn development CD.D18.PACE.MEM 474 TAT CENTER RIDGE DESIGN SERVICES INC. P.A.

TO: 206 431 3665 MAY 10, 1991 7:36AM #741 P.02 SCHEDULE INFORMATION AT BUS STOPS D M1 CITY OF TUKWILA PLANNING DEPT. Metro has two types of schedule information hardware at bus stops: information signs and schedule holders. Information signs can display route schedules, promotional materials, miscellaneous customer information, and a map. Information signs are large displays bolted to sidewalks or special landing pads. They are available in three sizes: small information sign, large information sign, and three -sided information kiosk. Schedule holders are mounted to bus stop sign posts and are available in two sizes: standard and mid -size. A standard schedule holder can display one to five schedules and can be installed singly or paired. Mid -size schedule holders are equivalent to six standard schedule holders and are always installed as a pair back -to -back on bus stop sign posts. I. Guidelines for Information Signs A. Placement Criteria • Placement is at bus stops with multiple routes, particularly in downtown areas, transfer points, and park- and -ride Tots. There are approximately 250 information signs in the service area. • Locations are determined by service frequency, passenger volumes and major transfer centers. The size of information sign is determined by the amount of information necessary at the bus stop. • Installation is 90 °to curb at the head of the bus zone, schedule side facing toward the oncoming bus. B. Design Guidelines • Schedule information is formatted in vertical columns reading in sequential order from left to right and top to bottom. • Schedule information is copied onto a water - resistant paper which is installed in the sign. • The frames are made of black anodized aluminum, the route and information panels are made of painted white aluminum, and the schedule information is protected with laminated glass. • Dimensions: Small information sign - 90" high x 22 -3/4" wide TYRMInat: G_1 • ,FROM:METRO SERUICE DE OP.

Guidelines for Schedule Holders A. Placement Criteria • Schedule holders are placed at the majority of inbound bus stops (stops where buses are headed toward major CBD areas), transfer points, and at key outbound stops. • Approximately 4,800 zones have schedule holders mounted to bus stop sign posts or shelter frames. About 115 zones have mid -size schedule holders and 760 have two standard schedule holders. • installation is on bus stop posts 90° to curb, facing toward the oncoming bus. If this is not practical, the schedule holder may be placed facing toward the street. 8• Design Guidelines • Schedule information is formatted in vertical columns reading in sequential order from left to right and top to bottom. • Schedule information is copied onto a water - resistant paper which is installed in the sign. • Schedule holders are made of sand cast aluminum, black anodized, with clear plexiglass protecting the schedule information. • Dimensions: Standard schedule holder • 21- 13/16" high x 3" wide Mid -size schedule holder - 22 -3/16" high x 9 -1/8" wide 111. General Guidelines Schedule holders are used more extensively than information signs because they are much less expensive, more vandal - resistant, and easier to maintain. Bus stop schedules are produced and installed at each service change. Also, an on -site inspection and minor cleaning of the information signs occurs at service change. Signs and information that have been vandalized between service changes are replaced as those reports are received. Twsoo1 /2& 6 -2 MAY101991 CITY OF TUKWILA PLANNING DEPT. FROM :METRO .

Pedestrians passing .through the center should be sepal tr4 from those who are waiting, transferring between buse,,, queuing to board and deboard. b. The curb space immediately adjacent to the bus loading should be free of all street level obstacles; except for t i ,ur, . stop signs, all street furniture (trash cans, benches, payphe,)ite4, light standards, shelters and information displays) and retat� rl pedestrian amenities should be set in 8 feet from the c car I> where space is available. Where space is not available, the minimum lateral clearance is 3 feet. Street furniture should hp placed so it does not block the operator's view of intending passengers or obstruct sight distance. Minimum height clearance for all signs in the bus stop zone should be 7 ffri from the bottom of the sign to the ground. Overhanging trE r• branches should be at least 8 feet from the ground so as no 1.) obstruct signage or interfere with mirrors on the coaches. c. Pedestrian spaces should be designed to be accessible. 1,-; people with disabilities. This includes ramps, curb cuts, ,.rid other architectural measures such as braille signage, audihlr signals, and textured walkways to minimize or eliminaip barriers for people with visual impairments or otl,ei disabilities. Paving materials in pedestrian areas should provide traction to reduce the risks of falling or slipping. p o ide gold also be taken to vary pavement ttexturmmunica�te function and spatial relationships for patrons with si t.ri impairments. e. Pedestrian spaces should be well lit and should have clear sight lines throughout the facility to promote a secure environmetit for the users. Passenger shelters should provide a view of passengers through the side panels. Street furniture and shelters should be constructed of durable, vandal resistant materials. Aesthetics and maintenance neeclf: should be considered in the initial design. General Transit centers should be designed to minimize conflicts between c and pedestrians and between buses and autos, both on -site and off-site. te. 2 -8 'FROM :METRO SERUICE D1WOP.

The concept provides nine (9) parking spaces to replace the eight (8) existing spaces which will be displaced by the right -of -way taking and sidewalk easements. In order to accomplish. the above, it will be necessary to relocate the existing access drive approximately 65' to the north and to move the existing parking spaces into landscape areas east of the existing parking lot. This concept will provide the required number of parking spaces adjacent to the existing entrance while accommodating the Metro pull -out. It is our understanding that the City of Tukwila will acquire and pay for all right -of -way and easement areas required to develop the northbound pull -out and signal installation and will pay for the construction of the revised parking lot configuration and all related improvements on the Fatigue Technologies Parcel. Jacobs, Visconsi & Jacobs has agreed to provide the design and construction documents for the parking area in conjunction with the development of the Phase I bus pull -out areas. I am also including for your review legal descriptions for the sidewalk easements and the Metro bus pull -out right -of -way dedication that Southcenter is proposing to deliver to the City of Tukwila along with a description of the sidewalk easement required on the east side of Andover Park West and the right -of -way dedication necessary for the northbound bus pull -out. Mr. Ron Cameron May 2, 1991 Page 2 Please feel free to contact me at your convenience if you have any questions or comments regarding any of the attached information. As you know, we are working towards a May 17th deadline for completion of construction documents for the Phase I bus pull -out areas, therefore, we would appreciate the comments of Fatigue Technology as well as the Public Works Department at your earliest convenience.

During our discussions with Public Works we expressed our belief that the Mervyn's /Mall Shop expansion would not increase the fire flow requirements since sprinkler demand is based on the largest loss or highest risk. In other words, the demand is not additive. Since the flow requirements from any one of the existing department stores exceeds the demand for the proposed Mervyn's or Mall Shop expansion, there will not be any additional fire flow demand on the system. The attached analysis prepared by Stecklow & Associates Company, PA with assistance from Factory Mutual Engineering (FM) supports our opinion that based on NFPA, Industrial Risk Insurers (IRI) and Factory Mutual requirements, there will be adequate water supply to provide fire sprinkler service at the property after the addition of Mervyn's and mall expansion. Additionally, the analysis demonstrates that the capacity of the existing water supply system far exceeds NFPA IRI and Factory Mutual standards as well as the City of Tukwila's own standards. The Tukwila comprehensive water plan states that a minimum of 2,000 GPM must be provided at a minimum residual pressure of 30 psi. The attached Factory Mutual test data indicates that a supply of 3,000 GPM is available to the project at a residual pressure of approximately 69 psi (see attached Factory Mutual correspondence and curve data). The above information clearly confirms that an adequate water supply for fire protection will be available at Southcenter Mall after the expansion to satisfy NFPA, Factory Mutual and the City of Tukwila's comprehensive plan requirements. Mr. Jack Pace April 30, 1991 Page 2 Further, taking into consideration Public Works feeling that the site should ' be considered light industrial requiring a minimum flow of 3,000 gallons per minute at a 30 psi residual pressure, the available flow of 3,000 GPM at 69 psi from the existing 8" water line will satisfy that criteria as well.

It is our opinion hat, per NFPA, per IRI and per Factory Mutual requirements, there will not be any additional water demand for fire /sprinkler service at the property with the addition of Mervyns since the demand on sprinkler systems are not z additive per building. The existing demand from either the M Frederick and Nelson, or from the Nordstrom, or from the Bon, or from J.C. Penneys, or from the Mall /Mall shops is as much as will be the demand from the proposed Mervyns store. AIR CONDITIONING VENTILATING The capability of the water supply system, per the flow tests performed by IRI and previously by FM, indicate the public water supply systems far exceeds not only the requirements of NFPA, IRI, and FM but also that of the City of Tukwila as it relates to capacity. The City of Tukwila's Comprehensive Water Plan states that for a commercial area a minimum of 2000 gpm be provided at a minimum residual pressure of 30 psi. The correspondence from the Staff Report states consideration should given to considering the site light industrial, which would increase the minimum flow requirement to 3000 with the 30psi residual minimum. Even though I do not believe a shopping center /department store is light industrial, the current water supply system, with the 8" feed mains on Andover Park West, exceeds these requirements. Per the FM test, a supply of 3000 gpm is available with a residual'' pressure of approximately 69 psi, as so noted on the attached curve and FM correspondence. 0 W I can understand the City's long term plan to provide minimum feed main sizes, however, to require a replacement of a line which has capacity to exceed the City's own requirements does not seem appropriate. It would be logical, if the City wants to revise this line to a 10 ", the City should do so when the line requires replacement due to poor condition. Cordially, STECKLOW ND ASSOCCIATES CO. P.A.

The closest Factory Mutual water test to this site was run on Southcenter Parkway, just north of the Southcenter Mall. The test results were a static of 146 psi reducing to 110 psi with a flow of 2522 gpm. This test compares favorably to other tests in the area. Based on the topographic map you faxed me of the area around the mall, the site is relatively flat and elevation loss between the test site and the mall is of no significance. Adjusting the above test through the mall lead in from 57th Ave. and the 10 and 12 inch loop around this mall shows 3000 gpm at 69 psi should be available at the south corner of the loop near the TBA store. This should be more than ample for fire protection purposes and exceeds Factory Mutual requirements for retail facilities. If you have any questions or wish to discuss this further, please call.

SOUTHCENTER MALL EXPANSION - PROPORTIONATE TRAFFIC IMPACTS Dear Tom, Based on our April 25 meetings with the City of Tukwila. the only outstanding transporta- tion issue involves identifying the Southcenter Mall Expansion project's proportionate share of three intersection improvements. In order to finalize the transportation mitigating mea- sures, JVJ and the city requested that TRANSPO provide estimates of the project's propor- tionate shares based on the city's methodology. This letter summarizes the proposed inter- section improvements and project proportionate shares. It also addressed potential level - of- service changes with the addition of other potential development in the area. Intersection Improvements The City of Tukwila has identified several transportation improvements in the vicinity of Southcenter Mall. Of particular interest are three intersection improvements that will be impacted by additional traffic resulting from the expansion of the mall. These intersections and the proposed improvements are summarized below: Intersection Proposed Improvement • Southcenter Parkway at Construct additional Strander Boulevard west -to- south, left-tum lane •. Andover Park W at Strander Boulevard • Andover Parts E at Tukwila Parkway Proportionate Share Widen to provide for left-tum lanes on north and south approaches Install traffic signal Mr. Ron Cameron, City Engineer, indicated that the project's proportionate share at these locations should be calculated by dividing project traffic increases by the total traffic increases between the existing counts and 1993 traffic forecasts. Ron indicated that the proportionate share impact for the two Strander Boulevard intersec- tions should be estimated using noon or PM peak hour traffic volumes. Proportionate The TRANSPO Group, Inc. 14715 Bel -Red Road, Suite 100 Bellevue, Washington 98007 FAX:2061747 -3688 2061641 -3881 Mr. Thomas Schmitz April 30, 1991 Page 2 The- Transpo Group share for the Andover Park E/Tukwila Parkway intersection should be based on daily traffic volumes, since it is a traffic control (signalizzation) improvement. TRANSPO's analyses of this intersection focused on noon and PM peak hour volumes; daily volumes are not avail- able. The percentage of retail traffic generation during the noon and PM peak hour is fairly consistent with daily variations in traffic in the site vicinity. Therefore, an average of the noon and PM peak hour proportionate shares can be used to estimate the daily proportion- ate share. The 1993 forecast traffic volumes are to include traffic from the proposed mall expansion and other proposed developments in the area. These other developments include the pro- posed redevelopment of the 3M site on the east side of Andover Park W and Southcenter Plaza Phase II, south of Strander Boulevard. Traffic volumes from these projects were not included in our traffic analysis for the project since they were not identified by the city when we scoped the study. The resulting proportionate share impacts for the Southcenter Mall Expansion are summa- rized in the Attachment. The project's proportionate share ranges from an average of 4.7 percent at Strander Boulevard /Southcenter Parkway to an average of 25.4 percent at Strander Boulevard /Andover Park W. Project share at Andover Park E /Tukwila Parkway averages 14.8 percent. Ron indicated that these improvements would cost an estimated $100,000 each; these are rough ball park cost estimates which Ron has agreed to refine. Based on these rough cost estimates and the project's average proportionate share, the Southcenter Mall Expansion project would contribute $44,900 toward these improvements. It is recommended that the city pool these monies with funds from other developments to fund one of the two Strander Boulevard projects. In this manner, the city will be able to more quickly improve traffic operations in the vicinity of the project site. Levels of Service Intersection levels of service were reanalyzed including the additional traffic from the poten- tial redevelopment of the 3M site and Southcenter Plaza Phase II. The additional traffic from these projects would not significantly alter the previous forecast level -of- service findings at the above three intersections. With the addition of traffic from the two projects, the intersection of Strander Boulevard/ Southcenter Parkway is forecast to operate at a calculated LOS D (27.3 seconds delay) dur- ing the noon peak hour, and LOS D/E (39.5 seconds of delay) during the PM peak hour. During the PM peak hour, the north -to -west left turns at the intersection of Andover Park E/ Tukwila Parkway will operate at LOS F in 1993 unless a signal is installed. With installation of a traffic signal. the intersection will operate at a forecast LOS C even with the additional traffic from the 3M site. The intersection of Andover Park W /Strander Boulevard will operate at a 1993 noon peak hour LOS E (49.1 seconds of delay) with the addition of the 3M traffic and no improve- ments. The addition of left -turn lanes on the north and south approaches will provide a 1993 noon peak hour LOS D (32.3 seconds of delay).

Mervyn's. 8aCkground - what, _ where. when_, why A proposal has been received from Dayton Hudson Corporation to build a MERVYN'S at the east end of Southcenter Mall. Water test data was provided by Industrial Risk Insurers listing the fire hydrant at Strander and Andover Park West with 1592 gpm at a static pressure of 147 psi. ISSU& Anal VSi S - a t erl ?a t.1. ties costs ..... impact The water test information does not meet our minimum design stan- dards or Tukwila's Water Comp Plan for the following reasons: 2000 gpm is required in commercial areas (Table 16 copy from Water Comprehensive Plan with HDA letter is attached.) Fire storage is considered inadequate to meet the 6000 gpm for a 6 -hour fire. Only data on a single hydrant is given and its location is not near the proposed development (comments from Nick Olivas, Fire Department). It is worth noting that the comprehensive modeling for a typical fire flow event considers the 2000 gpm an absolute minimum for a 7- Eleven or a Wendy's. Viewing this from a fire flow perspective, Mervyn's falls into a category more appropriate to light indus- trial which specifies 3000 gpm. The TMC 14.04.060 states that in areas zoned for industry or com- merce, mains shall meet the minimum design standards unless a larger size is required by the Public Works Director. Stringent application of the City's Comprehensive Plan is appropriate in this case. Also Horton Dennis and Associates points out that case by case studies for the minimum required fire flow are recom- mended for major buildings.

City of Tukwila Public Works 6300 Southcenter Blvd. Tukwila, WA 98188 SUBJECT: PROPOSED MERVYN'S DEVELOPMENT - WATER SYSTEM REQUIREMENTS Dear Ron: In response to your request, we have identified the requirements put forth in the 1985 Comprehensive Water System Plan and Draft 1990 Comprehensive Water System Plan Update for the area east of the Southcenter Shopping Mall, along Andover Park West. It is our understanding that there is a 100,000 square foot commercial development proposed for this area. As indicated on the attached copy of Minimum Design Criteria taken from the 1983 Comprehensive Water System Plan the minimum required fire flow for commercial buildings within the City. is 2,000 gpm, with case by case studies recommended for major buildings. Case by case studies are recommended for those buildings which would probably require flows greater than the required minimum. No changes to this minimum requirement have been proposed in the Comprehensive Water System Plan Update which we are currently working on. Although determining fire flow requirements of any proposed development will ultimately be the responsibility of the City Fire Marshall, the Comprehensive Plan and, subsequently, the. "Public Works Water Construction and Development Standards" have been developed as guidelines for determining minimum pipe sizes required to meet the minimum flow requirements mentioned above. The 1983 Comprehensive Plan indicates the need for a minimum 10 -inch line on Andover Park West in order to accommodate any future development in this area. As indicated on the enclosed copies, the City's "Development Standards" support this recommendation by requiring that: "All extensions, additions, changes or alterations to the City water system shall be consistent with the Comprehensive Plan" (page 3); and, "Minimum commercial, industrial or multiple family unit water mains shall be minimum of ten inches (10 ") in diameter for looped and twelve inches (12 ") in diameter for non - looped systems or per the size required by the City's Comprehensive Water Plan, whichever is greater."

The purpose of this study is to identify any potential adverse transportation - related impacts and to identify measures which may be required to mitigate the project impacts. Project Description As shown in Figure 1, Southcenter Mall is located in the southeast quadrant of the I- 5/I405 interchange. Jacobs, Visconsi, Jacob is proposing to add a fifth major depart- ment store and some additional mall shops to the existing center. The expansion would include an 82.940 -square foot (sf) department store and additional mall shops with a total of 21,446 gross square feet of leasable floor area (gsfla). The proposed expansion is planned for the northeast side of the mall, as shown in Figure 2. This expansion would increase the shopping center from just over 1,190,000 gsfla to 1.294,852 gsfla. In addition to the shopping center, the Southcenter site includes several fringe developments. These developments include a post office. movie theater, ser- vice station, and bank, totaling 37,393 sf. Including these fringe developments, the total site would include 1.332,245 gsfla including the 104.386 gsfla expansion. An existing 100,000 gsf motel located in the southwest portion of the Southcenter site is not included in the floor area calculations. A total of 6,662 parking spaces will be available on the Southcenter site, exclusive of the 326 parking spaces for the motel. The overall parking ratio with the expansion would be 5.0 parking spaces per 1.000 gsfla of floor area, exclusive of the motel parking spaces. Study Purpose The study area and specific traffic analyses presented in this report were identified through meetings and phone conversations with Mr. Ron Cameron, City of Tukwila Engineer. The initial meetings and analyses occurred in late 1989 when an initial expansion plan was being proposed by Southcenter Mall. Those plans have been revised into the cur- rent proposal. Recent discussions with Mr. Cameron confirmed and updated the study 89348.50/893485R1 The TRANSPO Group, Inc. Page 1 North Reproduced with permission granted by THOMAS BROS. MAPS.

Page 6 EXISTING CONDITIONS Street System Southcenter Mall is located in the southeast quadrant of the I -5 /I -405 interchange. These freeways have on and off -ramps which facilitate traffic flow to /from the shopping center and other commercial developments in the vicinity of the mall. Figure 4 shows the other major streets in the immediate vicinity of the mall Each of these facilities is briefly described below: • Strander Boulevard is a five -lane arterial on the south side of the shopping center. It provides east -west traffic flow between Southcenter Parkway and the West Valley Highway (SR 181) east of the site. In the immediate project vicinity, traffic signals are provided at its intersections with Southcenter Parkway and Andover Park W. A traffic signal has recently been installed at the intersection of Strander Boulevard and 61st Place S in conjunction with the recently developed Target Center on the south side of Strander Boulevard. There are no continuous sidewalks on the north side of Strander Boulevard between Andover Park W and Southcenter Parkway. • Southcenter Parkway is a five -lane north -south arterial adjacent to the west side of the shopping center. It provides access to Southcenter and many other com- mercial developments south of the mall Its intersections with Strander Boulevard, Klickitat Drive, and the I -5 northbound off -ramp are signalized. Pedestrian walk- ways exist on the east side of Southcenter Parkway adjacent to the mall site. • Klickitat Drive is a four -lane arterial connecting Southcenter Parkway with areas west of I -5. It provides access from the Southcenter area to southbound I -5. • Tukwila Parkway is a five -lane arterial paralleling I -405. It is used to connect to areas north of I -405 via 61st Avenue S (S -line bridge) and 68th Avenue S (T -line bridge). Traffic signals currently exist at its intersections with 61st Avenue S. the I -405 eastbound on -ramp. and Andover Park W. Pedestrian facilities are pro- vided along most of Tukwila Parkway, adjacent to the mall 89348.00 The TRANSPO Group, Inc.

The intersections of Andover Park W /Tukwila Parkway and Andover Park W /Strander Boulevard are signalized; the intersection of Andover Park W /Baker Boulevard is unsignalized. No pedestrian facilities are provided adjacent to the mall • Andover Park E is a four -lane north -south arterial east of the project site. Its intersections with Tukwila Parkway and Baker Boulevard are currently controlled with stop signs. • 61st Avenue S is a short four -lane arterial crossing I-405. It connects Tukwila Parkway with Southcenter Boulevard. Westbound traffic on I -405 uses 61st Avenue S to access the Southcenter commercial district. Traffic signals control traffic flow at both the Tukwila Parkway and Southcenter Boulevard intersections. • Southcenter Boulevard is a five -lane east -west arterial north of I -405. It con- nects to Interurban Avenue (SR 181) on the east and provides access to loca- tions west of I -5. Westbound I -405 has a ramp which connects to eastbound Southcenter Boulevard to provide access to the mall and surrounding commer- cial development. Access to eastbound I -405 is via Tukwila Parkway. Traffic Volumes, Levels of Service, and Warrant Analyses In order to provide a baseline for developing future traffic volumes and operations analyses. TRANSPO collected existing daily and peak hour traffic volume information from the City of Tukwila. These traffic volumes were supplemented with 1989 and 1991 manual noon and PM peak hour turning movement counts conducted by Trafticount. Inc., and TRANSPO at all analysis intersections (see Figure 3). At some locations. 1987 and 1988 City of Tukwila counts were factored to estimate 1989 volumes. Existing traffic volumes are summarized on Figure 5. 89348.00 The TRANSPO Group, Inc.

Page 10 As previously noted, a proposed expansion plan was being developed in late 1989. At that time, TRANSPO and Trafficount collected new manual traffic counts at study area intersections. In order to check on the adequacy of using the 1989 counts as a baseline for this traffic impact study, TRANSPO reviewed the City of Tukwila control counts for nearby intersections. Table 2 summarizes the comparisons. Table 2. Comparison of 1989 and 1990 City of Tukwila Control Traffic Counts Intersection Average Daily Traffic Volumes' 1989 1990 Percent Change • Klickitat Dr w/o 53rd Ave 15,126 15,025 -0.7% • 17,000 Southcenter Parkway 26,742 26,648 -0.4% • Southcenter Blvd w/o S-line 32,373 32,190 -0.6% • Andover Park W at Pond 12,849 14,262 +11.0% • Interurban Ave w/o Southcenter Blvd 21,776 23,380 +7.4% e. Source: City of Tukwila, Average of January through November counts (11 months). Control counts at three of the five intersections decreased slightly between 1989 and 1990. These three locations are located adjacent to or west of the shopping center. Average daily traffic volumes at the intersection of Andover Park west at Pond increased by 11.0 percent between 1989 and 1990. The largest increases at that intersec- tion occurred between July and November, reflecting the recent opening of the Target/ Tukwila Pond Center south of Strander Boulevard. Inasmuch as the full traffic impacts of the Target /Tukwila Pond Center are included in the forecast traffic volumes, this increase does not invalidate the use of the 1989 traffic counts as a basis for the traffic analysis. An increase of over 7 percent in daily traffic volumes is reported for Interurban Avenue north of Southcenter Boulevard. This location could have been impacted by con- struction on I-405 or other external factors. Since this count location is more removed from the project study area, it was decided to continue to use the 1989 traffic counts as a basis for developing future traffic volumes. Based on the 1989 noon hour and PM peak hour turning movement counts, level - of- service analyses were conducted for all of the study analysis intersections. The analyses were conducted using the methodologies presented in the Highway Capacity Manual, Transportation Research Board, 1985. 89348.00 The TRANSPO Group, Inc. Page 11 Level of service for signalized intersections is defined in terms of delay. Delay is a measure of driver discomfort, frustration, fuel consumption, and lost travel time. Specifi- cally, level -of- service criteria are stated in terms of the average stopped delay per vehicle for a 15- minute analysis period. Delay is a complex measure and is dependent on a number of variables including the quality of progression, the cycle length, the green time /cycle time ratio, and the volume -to- capacity ratio for the lane group or approach in question. Table 3 shows the level -of- service criteria for signalized intersections from the Highway Capacity Manual. Table 3. Level -of- Service Criteria for Signalized Intersections Stopped Delay Level of Service Per Vehicle (Seconds) A Less than 5.0 B 5.1to15.0 C 15.1to25.0 D 25.1 to 40.0 E 40.1 to 60.0 F Greater than 60.0 For unsignalized intersections, level of service is based on the reserve capacity available for each movement which has to yield or stop. Table 4 shows the level -of- service criteria and expected level of delay for unsignalized intersections from the Highway Capacity Manual. Table 4. Level -of- Service Criteria for Unsignalized Intersections Level of Service Reserve Capacity Expected Delay A 400 or more Little or no delay B 300 to 399 Short delays C 200 to 299 Average delays D 100 to 199 Long delays E 0 to 99 Very long delays F Less than 0 Failure - extreme congestion The results of the noon peak hour and PM peak hour levels of service are summa- rized in tables 5A and 5B, respectively.

Appendix A includes the adjusted and unadjusted worksheets. 3 Based on calculated delay per 1985 Hiahwav Capacity Manual. Field observations indicate a lower existing PM peak hour LOS for Southcenter Parkway/bidatat Drive and Strander Bou/evard/Southcenter Parkway. rn Refer to Figure 3. All of the signalized intersections that were analyzed were found to currently operate at LOS D or better during the noon and PM peak hours. However, some of the approaches and specific traffic movements operate at lower levels of service as discussed below. Strander Boulevard /Southcenter Parkway During the noon peak hour, this intersection is calculated to operate at an overall LOS C. Two turning movements are, however, calculated to operate at LOS D —the west -to- south left turns and the south -to -east left turns. During the PM peak hour, the intersec- tion is calculated to operate at an overall LOS D. 'the south -to -east left turns are calcu- lated to operate at LOS E, reflecting longer average delays for this movement. Field observations and measurements indicate an overall noon hour level of service of LOS D with over 30 seconds of average delay per vehicle. Although the overall intersec- tion was observed to operate satisfactorily, two movements were observed and measured to operate significantly worse. The west -to -south left turn operated at LOS F with nearly 80 seconds of delay per vehicle during the noon hour, while the northbound thru move- ments on Southcenter Parkway were measured to operate at LOS E, with 50 seconds of delay per vehicle. These poor levels of service result in lengthy traffic queues both east and south of the intersection. These queues block driveway access /egress which further com- plicates traffic operations near the intersection. The south -to -east left turn, which was calculated to operate at LOS D, were observed to operate at LOS B. This improved level of service (compared with the calculated level of service) reflects the coordination between the intersections of Southcenter Parkway at Klickitat Drive and Strander Boulevard. Although no measurements were taken during the PM peak hour. similar traffic operations were observed. Again, the west -to -south left turns were observed to operate at LOS E /F, with lengthy traffic queues. Klickitat Drive /Southcenter Parkway This intersection is calculated to operate at an overall LOS C during both the noon and PM peak hours. During the noon peak hour, the east -to -north left turn calculates to 89348.50/893485R1 The TRANSPO Group, Inc. Page 17 operate at LOS D, while all other movements are LOS C or better. During the PM peak hour, the east -to -north left turn calculates to operate at LOS E with all other movements at LOS C or better. Field observations and measurements were conducted to confirm the noon hour level of service. The measurements indicated that the east -to -north left turn actually operates at LOS F with an average of 95 seconds of delay per vehicle. All other movements were observed to operate at LOS D or better. The northbound traffic movements were all observed to operate at LOS B, reflecting the coordination between this intersection and the signalized intersection of Strander Boulevard and Southcenter Parkway. Although no measurements were taken during the PM peak hour, similar compari- son with the calculated level of service were observed. 1 -5 Northbound Off -Ramp/ Southcenter Parkway During the PM peak hour, the eastbound and westbound approaches at this intersec- tion are calculated to operate at LOS D, with the northbound and southbound approaches operating at LOS B /C. Overall, the intersection operates at LOS C during the PM peak hour. Tukwila Parkway /61st Avenue S This intersection is calculated to operate at an overall LOS B during the PM peak hour. Longer delays exist for the east -to -north left turns and westbound thru traffic movements which operate at LOS D. The level of service at the intersection can worsen significantly when traffic queues from the intersection of Southcenter Boulevard and 61st Avenue S block the intersection. The traffic queues may be able to be reduced with a signal interconnect between these two closely spaced intersections. 89348.50/893485R1 The TRANSPO Group, Inc. Page 18 Southcenter Boulevard 161st Avenue S This intersection was calculated to operate at an overall LOS B/C during PM peak hour. The eastbound thru and west -to -south left -turn movements operate at LOS D during the PM peak hour. Due to the close spacing of traffic signals on 61st Avenue S, the level of service of this intersection can worsen due to the potential for southbound traffic queues to extend back from the intersection of 61st Avenue S at Tukwila Boulevard. These traffic queues can block the east -to -south right turns and the west -to -south left -turn movements, resulting in longer delays at the intersection. Strander Boulevard 161st Place S This intersection was recently signalized in conjunction with the development of the Target Center on the south side of Strander Boulevard. Based on 1991 traffic counts, the intersection is calculated to operate at LOS C during the noon and PM peak hours. The west -to -south left turns into the Target Center are calculated to operate at LOS E during both of these time periods; all other movements operate at LOS D. Strander Boulevard /Andover Park W During the noon and PM peak hour, this intersection operates at an overall LOS D. However. the east -to -north and west -to -south left turns operate at LOS F during both time periods. Much of the delay at the intersection results from the lack of left -turn lanes on the north and south approaches, which in turn requires split signal phasing. As will be dis- cussed later, the City of Tukwila has plans to widen Andover Park W to five lanes, including north -south left -turn lanes at this intersection. Tukwila Parkway /I-405 On Ramp Based on April 1991 traffic counts, this intersection is calculated to operate at LOS C during the noon and PM peak hours. The only movement that operates at or below LOS E is the west -to -south left turn. This left turn operates at LOS E during the noon and PM peak hours; however, fewer than 50 vehicles access Southcenter Mall via this left -turn movement during these peak time periods. 89348.50189348581 The TRANSPO Group, Inc. Page 19 Tukwila ParkwaylAndover Park W This signalized 'T' intersection operates at an overall LOS C during both the noon and PM peak hours. All movements currently operate at LOS D or better. Tukwila Parkway /Andover Park E During the noon and PM peak hours, this unsignalized 'T' intersection currently operates at LOS E for the north -to -west left turns. This calculated level of service is based on adjusted traffic volumes on the east -west thru movements to reflect the larger number of available gaps typical of multiple lane facilities. The City of Tukwila is proposing installation of a traffic signal at this intersection to improve traffic operations and safety. Installation of a signal will eliminate the LOS E condition. PM peak hour levels of service were also calculated based on the 1989 traffic vol- umes for five unsignalized driveways to the shopping center. It should be noted that the level -of- service analyses were adjusted to reflect the increased number of gaps in the thru traffic on the major streets resulting from the multiple travel lanes in each direction and the effect of nearby traffic signals. Both the adjusted and unadjusted worksheets are included in Appendix A. In addition to the PM peak hour levels of service, traffic signal warrant analyses were conducted for each of these driveways. The warrant analyses were conducted using the 1989 baseline traffic counts. The warrant analyses worksheets are included in Appendix B and were conducted based on the criteria outlined in the Manual of Uniform Traffic Control Devices (MUTCD). FHWA. The following summarizes the resulting level -of- service and warrant analyses for the five unsignalized driveways. 89348.50/893485R1 The TRANSPO Group, Inc. Page 20 Southcenter Parkway/ S 159th Street (West Theater) The west theater entrance consists of a single 15 -foot wide exit lane intersecting with the four -lane Southcenter Parkway. A left -turn acceleration lane is provided on Southcenter Parkway to provide refuge for vehicles making the west -to -south left turn. Based on the adjusted traffic volumes, the west -to -south left turn is calculated to operate at LOS D/E during the PM peak hour, which is consistent with field observations. The west -to -north right -turn movement is relatively minor with fewer than 30 vehicles during the PM peak hour. This right turn also operates at LOS D/E due to the existing shared lane configu- ration. If a separate right -turn lane were provided. the right -turn movement would operate at LOS A. Based on 1989 traffic volumes, the intersection meets two of the traffic volume war- rants presented in the MUTCD. The intersection meets the criteria for Warrant 2 (interruption of continuous traffic) and Warrant 9 (four -hour volumes). Warrant 1 (minimum vehicular volume) is met seven hours of the day, just under the eight hours required to satisfy the warrant. Tukwila Parkway/ 59th Avenue S (North Theater) This intersection currently operates at LOS D or better for all movements. LOS D is calculated for the north -to -west left turn which impacts fewer than ten vehicles during the PM peak hour. Northbound right turns are calculated to operate at LOS A during the PM peak hour. Observations indicate longer delays than calculated due to traffic queues extending west of the Tukwila Parkway /61st Avenue S intersection. These traffic queues also result in a worse than calculated LOS A for the west -to -south left turns. The resulting delays for the west -to -south left turn are minimized since many eastbound drivers do not block the shopping center driveway, allowing the left turns to be made safely. Based on the 1989 traffic volumes, this intersection meets traffic signal Warrants 2 (interruption of continuous traffic) and 8 (combination of warrants). However the majority of the minor street traffic (northbound) are right turns which would not be greatly improved by the installation of a traffic signal. 89348.50/893485R1 The TRANSPO Group, Inc. Page 21 Andover Park WIS 159th Street (Union 76 Entrance) All movements at this intersection currently operate at LOS B or better during the PM peak hour. The east -to -north left turns would operate at. LOS C. and the east -to -south right turns would operate at LOS A if two exiting lanes were provided. The existing traffic volume and lane configuration would meet the MUTCD criteria for Warrants 1 (minimum vehicular traffic) and Warrant 9 (four -hour volume). However, given the good level of service and proximity to the signalized intersection of Andover Park W at Tukwila Parkway, a signal at this driveway would probably not be needed nor desirable. Andover Park W /Baker Boulevard This four -leg intersection currently operates at LOS C or better during the PM peak hour. The majority of the traffic exiting the shopping center makes a right turn. which operates at LOS A. Westbound traffic at the intersection also operates at LOS A for right turns and LOS C/D for the thru /left -turn movements. Based on 1989 traffic volumes, this intersection did not meet traffic signal warrants as identified in the MUTCD. The intersection volumes are, however, within ten vehicles of meeting the criteria for Warrant 9 (four -hour volume). Andover Park W (north of Strander Boulevard) Three minor driveways are located along this section of Andover Park W. The southernmost driveway provides access to a bank. the center driveway serves the post office. and the northernmost driveway provides access to a tire store and to the outer parking areas of the shopping center. During peak travel periods, southbound traffic queues from the intersection of Strander Boulevard /Andover Park W blocks one or more of these driveways. Traffic exiting the driveways is delayed due to these queues. Observations indicated only minor traffic 89348.50/893485R1 The TRANSPO Group, Inc. Page 22 volumes at each of these driveways, primarily due to the traffic queues. The north -to -west left turns entering these driveways also are delayed by the southbound traffic queues. Vehicles stopped to make this left turn were observed to block northbound thru traffic resulting in delays to thru traffic. Strander Boulevard /58th Avenue S (just east of Doubletree Motel) This intersection currently operates at LOS D/E for the south -to -east left turns exiting the shopping center. In 1989, only 33 vehicles were counted making this movement during the PM peak hour. The majority of traffic exiting the shopping center via this drive- way make a right turn onto westbound Strander Boulevard. The right -turn movement is calculated to operate at LOS A. However. westbound traffic approaching the intersection of Strander Boulevard at Southcenter Parkway may queue beyond this driveway during peak travel periods resulting in a worse level of service. The traffic signal warrant analysis shows that the existing traffic volumes and road- way geometry meet Warrant 2 (interruption of continuous traffic), Warrant 9 (four -hour volume), and Warrant 11 (peak hour volume). As previously noted, the majority of the traf- fic using this driveway is orientated to /from the west, reducing the actual need for a signal for exiting vehicles. The City of Tukwila is working with a developer to construct a new road in the 58th Avenue S corridor. The four -lane facility would connect Strander Boulevard with S 168th Street. This improvement project is currently proposed as a private road with likely construction no earlier than 1995. The proposed alignment for 58th Avenue S would intersect Strander Boulevard 100 to 150 feet west of this driveway. Current pro- posals call for restricting the intersection at Strander Boulevard to right -in /right -out. This would minimize conflicts with the existing Southcenter Mall driveway. At some time in the future, it may be desirable to relocate the existing stopping center access drive to form a four - legged signalized intersection at this location. This would only occur if and when the Doubletree Motel site is redeveloped, which could be 12 or more years. 89348.501893485R1 The TRANSPO Group, Inc. Page 23 Traffic Safety Traffic accident data provided by the City of Tukwila were analyzed to identify any safety concerns which could be impacted by increases in traffic associated with the project. Accident data were obtained for the three -year period between August 30, 1986 to August 30, 1989. These data were originally collected for the 1989 traffic analysis. Discussions with the city engineer indicated that analysis of 1990 accident data would not significantly alter the evalua- tion of safety issues in the study area; therefore. 1990 data are not included. The number of accidents for each of the three years ending August 30 are summarized in Figure 6. In general. most intersections and roadway sections in the immediate vicinity of the project have a relatively low occurrence of accidents, relative to the existing traffic volumes. The highest accident occurrences are found at the intersection of Strander Boulevard and Southcenter Parkway. A large number of accidents are also found on Strander Boulevard just east of Southcenter Parkway. Other signalized intersections which have relatively high accident occurrences are Klickitat Drive at Southcenter Parkway, Tukwila Parkway at 61st Avenue S. and Southcenter Boulevard at 61st Avenue S. The only unsignalized inter- sections with relatively high accident histories are the intersection of Andover Park W at Baker Boulevard and the intersection of Strander Boulevard with 58th Avenue S (adjacent to the Doubletree Motel). Strander Boulevard /Southcenter Parkway Eight (8) of the 21 accidents reported by the city during the three-year period at the intersection of Strander Boulevard and Southcenter Parkway were rear end accidents involving northbound vehicles on Southcenter Parkway. The other accidents at the inter- section showed no major patterns and included a variety of angle, approach turns, sideswipes, and collisions with parked vehicles or other fixed objects. 89348.50/89348581 The TRANSPO Group, Inc.

Page 25 Strander Boulevard (east of Southcenter Parkway) The section of Strander Boulevard adjacent to the Doubletree Motel has experienced a large number of accidents over the three -year period. Of the 31 accidents reported by the City of Tukwila, 24 involved vehicles entering or leaving one of the motel driveways. In all but 1 of the 24 accidents, the traffic from the motel driveways collided with westbound traffic on Strander Boulevard. Many of these accidents are likely due to the westbound traffic queues which block the driveways and restrict sight distance for exiting and entering vehicles. Three rear end and one sideswipe collisions also were recorded, all involving westbound traffic on Strander Boulevard. The other three accidents during the three -year period were right -angle collisions involving traffic accessing or egressing driveways on the south side of Strander Boulevard. The city engineer also indicated that pedestrians cross between the two hotels along this section of Strander Boulevard. Currently, there are no continuous pedestrian facilities on the north side of Strander Boulevard between Andover Park W and Southcenter Parkway, which results in these midblock crossings. Klickitat DrivelSouthcenter Parkway A total of 18 accidents were recorded at this intersection over the three -year analy- sis period. The most predominate type of accidents were rear -end collisions. Of the seven rear end accidents, five involved northbound vehicles, with one each involving southbound vehicles. The northbound rear -end collisions likely result from the close proximity of the Southcenter Parkway /Strander Boulevard intersection and traffic queues between the intersections. The other accidents included a variety of sideswipes (4), right angle (4), and colli- sions with fixed objects (3). No pattern was detected in these accidents which involved traffic from differing directions and times of day. Tukwila Parkway /61st Avenue S Of the 21 accidents recorded at this intersection over the three -year analysis period, 9 were of the rear end variety, 5 sideswipe, 3 right angle, and 4 others. Of the rear end 89348.50/893485R1 The TRANSPO Group, Inc. Page 26 accidents, the majority involved eastbound or southbound traffic. The sideswipe and right angle accidents involved a variety of approaches and movements at the intersection with no particular pattern. Southcenter Boulevard /61st Avenue S Eight (8) of the 14 accidents recorded at this intersection during the three -year time period were right angle accidents involving the north -to -west left -turn and eastbound thru traffic. The remaining accidents include three sideswipe and three rear end collisions, with half involving northbound vehicles on 61st Avenue S. Many of the accidents at this intersection are likely related to the short distance between intersections along 61st Avenue S which limits the distance that drivers have to react to changing traffic conditions. Andover Park W /Baker Boulevard A total of 14 accidents were recorded at this intersection over the three -year time period. Five of the accidents involved southbound traffic in collisions with westbound traf- fic on Baker Boulevard. Four other accidents involved southbound thru vehicles and north -to -west left turning vehicles. Three rear end accidents also were reported, all involv- ing northbound vehicles. No sight distance problems were observed that would create a safety hazard at the intersection. As previously noted, 1989 traffic volumes at this inter- section did not meet warrants for installation of a traffic signal. Strander Boulevard /58th Avenue S (adjacent to Doubletree Motel) A total of 13 accidents were recorded at this intersection over the three -year period ending August 30, 1989. Eight of the accidents involved westbound thru traffic and east - to -north left turns. Three of the remaining five accidents were angle accidents involving south-to -east left turns and westbound thru traffic. A rear end and sideswipe accident also involved westbound vehicles. Many of the accidents at this location appear to be related to the westbound traffic queues which extend from the intersection of Strander Boulevard and Southcenter Parkway. 89348.50/893485R1 The TRANSPO Group, Inc. Page 27 Planned Transportation Improvements The City of Tukwila has several transportation improvement projects proposed for the vicinity of Southcenter Mall. Table 6 and Figure 7 summarize the projects within the immediate study area. It should be noted that many of the projects listed are not currently funded. These projects were considered in developing the traffic mitigation program for the proposed expansion project. In addition to these projects, the City of Tukwila recently completed work on a long - range transportation improvement needs study. Draft recommendations for that study also were used in developing the traffic mitigation program. Table 6.

Page 29 FUTURE CONDITIONS WITHOUT PROJECT In order to asses the potential traffic impact of the proposed shopping center expan- sion, future baseline traffic volumes were developed and analyzed without the project. A forecast year of 1993 was selected to reflect the anticipated completion and occupancy of the proposed expansion. The 1993 without project traffic forecasts were developed in a two -step process. First, existing traffic volumes were increased by 1 to 2 percent per year based on PM peak- hour traffic trends in the area between 1986/87 and 1989. A 1 percent annual growth rate was utilized along Southcenter Parkway, Strander Boulevard, and Klickitat Drive, with a 2 percent annual growth rate utilized along 61st Avenue S, Andover Park W, Andover Park E. Southcenter Boulevard, and Tukwila Parkway. In addition to the background growth rate, the 1993 without project traffic vol- umes include traffic that will be generated by the Target /Tukwila Pond Center. The Target/ Tukwila Pond Center is a 160,000 square foot shopping center recently constructed just south of Southcenter Mall. Traffic volumes and assignments for that project were obtained from the tragic impact analysis supplied by the City of Tukwila. This process results in a 5 to 6 percent annual growth rate on Strander Boulevard adjacent to Southcenter Mall, with lower growth rates on other streets in the study area. The resulting 1993 without project traffic volumes are shown in Figure 8. Tables 7A and 7B summarize the resulting levels of service for comparison purposes. (See pages 32 -36.) The increase in traffic volumes without the project did not result in any significant changes in the levels of service for signalized intersections. All signalized intersections that were analyzed are forecast to continue to operate at an overall LOS D or better during the noon and PM peak hours. As described in the Existing Conditions section of this report, some traffic movements may operate at lower levels of service than shown in Tables 7A and 7B. The relative increase in overall vehicle delay at an intersection is, however, indicative of the impact of the increased traffic volumes. It should be noted that the city is proposing to widen Andover Park W to provide left -turn channelization on the north and south approaches at the intersection of Strander Boulevard. 89348.50/89348581 The TRANSPO Group, Inc. Page 30 This widening will reduce the need for splitting the north -south signal phase. With this improvement, the intersection is forecast to operate at an overall noon hour LOS D (30.8 sec- onds average delay) compared with LOS D (38.6 seconds of delay). During the PM peak hour, the improvement will reduce the average delay per vehicle from 36.6 seconds to 31.5 seconds, both LOS D. The improvement also will allow more green time for the east -west left turns, which are forecast to operate at LOS F under the existing roadway geometry. All but three critical movements at unsignalized intersections also will operate at LOS D or better. The south-to -east left turn from the shopping center driveway located just east of the Doubletree Motel (58th Avenue S) is forecast to worsen from an existing LOS D/E to a LOS E. This decrease in level of service is related to the increase in traffic along Strander Boulevard associated with the Target / Tukwlla Pond Center. Based on the 1993 without project traffic forecast, this poor level of service will impact fewer than 50 vehicles exiting this driveway during the PM peak hour. The west -to -south left turns from S 159th Street (W Theater driveway) onto Southcenter Parkway also are calculated to operate at LOS E during the PM peak hour. The existence of the left -turn acceleration lane, which was not accounted for in the level of ser- vice calculation, will probably provide a better forecasted level of service for these left turns. The north -to -west left turns at the intersection of Andover Park E/ Tukwila Parkway are forecast to operate at LOS F by 1993. As previously described, the city is planning to install a traffic signal at this intersection by 1994. Installing a traffic signal would provide a 1993 LOS C during both the noon and PM peak hours. 89348.50/893485R1 The TRANSPO Group, Inc.

Page 38 Trip Distribution and Assignment The project trips were distributed and assigned to the study area street system. The distribution was based on a review of a 1986 survey of shoppers at the mall The informa- tion presented in the market survey was collaborated through a review of the trip tables developed by the Puget Sound Council of Governments for their regional traffic models. The results of the distribution analysis are summarized in Figure 9. The distribu- tion results in 25 percent of the new project traffic orientated to /from the northeast in the I -405 corridor, 24 percent to /from the southeast, 14 percent to /from the southwest, 19 percent to /from the northwest, and 13 percent to /from the north. Five (5) percent were distributed to the local area immediately south and east of the center. Figure 10 summarizes the project traffic assignment in the immediate study area. Assignments to specific driveways took into account existing travel patterns, access to regional transportation facilities, and the location of the proposed expansion within the shopping center. Forecast Traffic Volumes and Traffic Operations Impacts The resulting project traffic assignment was superimposed on the forecast 1993 without project traffic volumes to obtain the 1993 with project traffic forecast. Figure 11 summarizes the resulting 1993 with project forecast. The largest increase in traffic associated with the proposed expansion project will be found on Andover Park W south of Baker Boulevard. During the noon peak hour, the pro- ject would add approximately 30 vehicles in each direction on this section of roadway. The project would add 25 vehicles in each direction during the PM peak hour. The project would increase forecast 1993 noon and PM peak hour volumes by 4 to 6 percent. These increases would reflect two years of traffic growth in the area, based on recent trends. Due to the variations in the on and off ramps to I -5 and I -405, traffic increases on Klickitat Drive, 61st Avenue S. and Southcenter Boulevard will vary by direction of travel. During the PM peak hour, the project will increase traffic volumes on westbound 89348.50/893485R1 The TRANSPO Group, Inc.

Page 42 Klickitat Drive by 30 vehicles, but will only increase eastbound volumes by 15 vehicles. These increases represent approximately 3 percent growth in noon hour and 2 percent growth in PM peak hour traffic compared with the 1993 without- project condition. These growth rates represent two years of traffic growth based on recent trends. The project would increase PM peak hour volumes on 61st Avenue S by 35 vehicles in the southbound direction and by 15 vehicles in the northbound direction. Impacts on Southcenter Boulevard also will vary by 20 vehicles, with 25 project trips eastbound and 5 westbound. Again, these increases represent less than a 2 percent increase in traffic volumes — equivalent to one to two years of background growth. Table 9 summarizes the project's traffic volumes during the noon and PM peak hours at key study area intersections. The table also summarizes the project's propor- tionate impact based on 1993 total entering vehicles (TEVs). Project traffic ranges from 0.6 percent of 1993 forecast traffic volumes at the intersection of Strander Boulevard/ Southcenter Parkway to 4.5 percent at Andover Park W /Baker Boulevard. Table 9.

Tables 11A and 1 1B summarize the level -of- service analyses for the 1993 with pro- ject scenario. The additional traffic generated by the project will not result in a decrease in overall level of service at any of the signalized intersections that were analyzed. The project will, however, result in slight increases in the average delay per vehicle at these intersec- tions. All of the signalized intersections are forecast to continue to operate at overall LOS D or better during the noon and PM peak hour, which is generally considered acceptable in urban areas. The potential for road improvement needs to reduce the impact of the project and to improve general traffic flow in the area are discussed below. Strander Boulevard /Southcenter Parkway As previously discussed, this intersection actually operates at a worse level of ser- vice than calculated per the Highway Capacity Manual Field observations and measure- ments indicate that the west -to -south left turns currently operate at LOS F during the noon peak hour. The northbound thru vehicles operate at a LOS E during the noon peak hour. These conditions result in long traffic queues that block driveways and impact traffic safety on the approaches to the intersection. Similar conditions were observed during the PM peak hour. 89348.50/893485R1 The TRANSPO Group, Inc.

Field observations indicate a bwer existing PM peak hour LOS for Southcenter Parkway/Klickitat Drive and Strander Boulevard/Southcenter Parkway. Refer to Figure 3. Strander Boulevard, and Klickitat Drive. Based on the analyses completed for this project, these projects will not be required prior to 1993. Planning and funding for the projects should, however, continue based on the city's long -range transportation plans. The proposed expansion project would have minimal impacts on traffic volumes and operations along this section of roadway. As previously discussed, the need to coordinate traffic flow between the intersections of Klickitat Drive and Strander Boulevard results in longer delays and worse levels of service than calculated per the Highway Capacity Manual methodologies. 61st Avenue at Tukwila Parkway As an option to improve traffic flow and reduce the impacts of traffic queues at the intersection of 61st Avenue S and Tukwila Parkway, the city is considering extending 61st Avenue S into the shopping center. This extension would provide direct access from 61st Avenue S into the shopping center, eliminating the need for traffic to make a right turn onto westbound Tukwila Parkway and a subsequent left turn into the site via 59th Avenue S (north theater driveway). The extension would eliminate the reverse movements for traffic exiting the shopping center. As previously described, these movements result in weaving maneuvers and traffic queues which add to congestion in the vicinity of the two intersections. 89348.50/893485R1 The TRANSPO Group, Inc. Page 49 Developing the extension without widening 61st Avenue S and /or Tukwila Parkway would eliminate the use of the existing overlapping of signal phases for complementary left and right -turn movements. The addition of the fourth leg of the intersection could require use of split signal phasing for all approach legs reducing the capacity of the intersection. Split phasing could be required because left turns would need to share travel lanes with thru traffic resulting in LOS F conditions and associated potential safety problems. The split phasing and reduction of the overlap phasing would likely create extensive traffic queues and increase delays on the S -line bridge which would impact traffic operations at the intersection of 61st Avenue S at Southcenter Boulevard. The addition of the south approach to the intersection would, however, reduce the existing traffic queues along Tukwila Parkway by closing the existing north theater driveway. which would enhance thru traffic flow along Tukwila Parkway. The draft recommendations of the City of Tukwila Transportation Plan includes a project to widen 61st Avenue S (including the bridge) between Southcenter Boulevard and Tukwila Parkway. This widening would allow a separate southbound thru traffic lane to pro- vide direct access to Southcenter and still allow separate left and right-turn lanes and more storage capacity between Tukwila Parkway and Southcenter Boulevard. If and when the city pursues the widening of 61st Avenue S. the potential addition of the south approach should be reevaluated. A short-term project to improve traffic operations at this and other nearby intersec- tions would be the interconnection of the traffic signals along 61st Avenue S (S -line bridge). A signal interconnect system would enhance traffic flow by reducing traffic queues which block the adjacent intersection. The city has a project to pursue interconnect systems in its Six -Year Transportation Improvement Program. Strander Boulevard at Andover Park W The 1993 noon peak hour level of service at this intersection is forecast to decrease from LOS D (38.6 seconds delay) to LOS E (41.3 seconds delay) with the proposed expansion. During the PM peak hour it is forecast to operate at LOS D with or without the expansion. 89348.50/893485R1 The TRANSPO Group, Inc. Page 50 Much of the delay at this intersection is related to the lack of left -turn lanes on the north and south approaches to the intersection. The lack of left -turn lanes requires split signal phasing and lower levels of service. The city has plans to widen Andover Park W to five lanes, including left -turn lanes on the north -south approaches of this intersection. This improvement will provide a 1993 noon and PM peak hour LOS D with or without the proposed expansion. The improvement will also greatly reduce potential delays on Strander Boulevard by providing additional signal timing for those movements. The proposed expansion accounts for 2.8 percent of the 1993 with project PM peak hour traffic volumes. The project is not currently funded, but is scheduled on the city's Six -Year Transportation Improvement Program for construction by 1994. Andover Park W at Baker Boulevard This unsignalized intersection is forecast to operate at LOS D during the 1993 PM peak hour with or without the expansion. However, city plans call for signalizing the inter- section when Andover Park W is widened to five lanes. Signalization of this east entrance to the shopping center will directly facilitate traffic to /from the proposed expansion area. Installation of a signal also will help distribute future traffic flows in the area. In particu- lar, a new signal may help relieve traffic operations at Andover Park W /Strander Boulevard by shifting some traffic to Baker Boulevard and Andover Park E. As part of the city's plans for widening project, the applicant has been working with Metro Transit and the city to provide bus pullouts on Andover Park W. These bus pullouts would replace the current bus stop adjacent to the mall entrance at The Bon Marche. The preliminary plans call for the bus pullouts to be located on the far side of the intersection (southbound buses would stop south of Baker, northbound buses, north of Baker). Estab- lishment of these new bus pullouts will further justify signalizing the intersection to provide for safe pedestrian crossings. The widening and signalization of the intersection of Baker Boulevard /Andover Park W could be completed as a first phase of the Andover Park W widening project. 89348.50/893485R1 The TRANSPO Group, Inc. Page 51 Tukwila Parkway at Andover Park E By 1993, this unsignalized intersection is forecast to operate at LOS F during the PM peak hour, with or without the proposed expansion. The LOS F is for the north -to -west left -turn movement. The city, as part of its project to widen Andover Park E to five lanes, has plans to signalize this intersection. Installation of a signal would provide LOS C with or without the project. 'Traffic from the proposed mall expansion will represent 1.5 percent of 1993 PM peak hour volumes. It is unlikely, however, that the project will directly add traffic to the poor north -to -west left -turn movement. Strander Boulevard at 58th Avenue S (Doubletree Motel) During the PM peak hour, the south-to -east left-turn movements at the unsignallzed intersection of Strander Boulevard and 58th Avenue S (just east of the Doubletree Motel) are forecast to operate at LOS E/F with the proposed expansion project. Fewer than 55 vehicles are forecast to make this turn during the PM peak hour. Although a traffic signal is war- ranted at the intersection, most of the exiting traffic makes a right turn onto westbound Strander Boulevard. These right turns would not greatly benefit from signalization. As previously discussed, the City of Tukwila is working with a developer to con- struct a new four -lane private access road in the 58th Avenue S corridor between Strander Boulevard and S 180th Street. Current plans indicate that the intersection of this new road with Strander Boulevard will be limited to right -in /right -out turn movements. This restriction will minimize the conflicts between the Southcenter driveway and this new roadway. Signalization is not currently recommended for either the existing Southcenter Mall driveway or the new four -lane roadway to the south (assuming right -in /right -out operation). 89348.50/893485R1 The TRANSPO Group, Inc. Page 52 If the Doubletree Motel site is redeveloped in the future (redevelopment would not likely occur for at least 12 years due to a current lease for the site), the city will likely request that the current driveway be relocated to align with the proposed four -lane exten- sion to the south. If this realignment occurs, it may be appropriate to signalized the inter- section and allow all traffic movements. The need and desire to signalize this intersection will need to be re- evaluated at that time. Southcenter Parkway at S 159th Street (West Theater Entrance) Left turns from S 159th Street (west theater driveway) onto Southcenter Parkway are also forecast to operate at LOS E during the PM peak hour. The forecast level of service does not. however, accurately reflect the provision of the left -tum acceleration lane at the intersection. As discussed in the Existing Conditions section of this report. this location currently meets the criteria for installation of a traffic signal. Installation of a traffic signal at this location does not appear to be appropriate. given the availability of the left-turn acceleration lane and minimal accident occurrence over the past three years. Widening of the west theater driveway to provide separate right and left -turn lanes would reduce delays for the right turning vehicles. Since fewer than 35 vehicles are fore- cast to make this right turn, widening of the driveway also is not necessary. All other analyzed intersections are forecast to operate at LOS D or better during the PM peak hour. The project would not result in a decrease in level of service at any of these intersections. Safety Vehicular The proposed expansion will increase traffic volumes on the streets in the project vicinity. The increase in traffic could lead to a slight increase in accidents in the area. Although there is no reliable method for forecasting increases in accidents, it is likely that the increase in accidents at any location would be proportional to the increase in traffic volumes. 89348.50/893485R1 • The TRANSPO Group, Inc. Page 53 The projects greatest impact on safety would likely occur at the intersection of Andover Park W and Baker Boulevard. This intersection will serve as a major entrance to the new department store. The addition of left -turn lanes and a traffic signal would help reduce the potential safety problem. It should be noted, however, that although a traffic signal is not currently warranted at this intersection (based on 1989 counts). a signal will likely be warranted in the near future. The project would add only minimal traffic to the three driveways located on Andover Park W immediately north of Strander Boulevard. Additional thru traffic along Andover Park W would, however, add to the traffic queues. resulting in longer delays and possibly increasing the number of accidents. Options include closing one or more of the driveways to minimize the number of conflict points and to discourage traffic using these driveways. Specifically, the center driveway which serves the post office could be closed. This driveway is located just north of the driveway to /from the bank and therefore would not result in a significant increase in travel distance for post office users. Another option would be to restrict tragic flows at the bank driveway to right -in- right -out only. This restriction would not impact a significant amount of traffic since many drivers currently avoid making left turns at this driveway because of traffic queues. The right -in /right -out restriction would reduce the impacts of southbound traffic queues on traffic exiting this driveway. The city has proposed widening Andover Park W to provide a continuous two -way left - turn lane between Tukwila Parkway and S 180th Street. Construction of a two -way left -turn lane would help facilitate traffic flow and safety along this section of Andover Park W. The increase in traffic volumes resulting from the proposed expansion will not, however. trigger the need for this widening. Pedestrian The city is also concerned about the lack of sidewalks along the Strander Boulevard and Andover Park W frontage and internal to the shopping center site. The lack of side- walks on these streets requires pedestrians to walk in the parking lot. Of particular concem are pedestrian crossings near the Doubletree Motel in the southwest corner of the shopping center site. There are no sidewalks connecting the motel 89348.50/89348581 The TRANSPO Group, Inc. Page 54 to the signalized intersection at Southcenter Parkway or to the recently signalized intersec tion at 61st Place S at the Target Center. The lack of these connections results in people crossing Strander Boulevard when and where there is a break in traffic. which can be very difficult and unsafe during most of the day. Topography, the lack of right of way, and the impact on motel parking will make installing a sidewalk adjacent to the motel very difficult. An option being discussed by the applicant and city calls for constructing a stairway to con- nect the motel parking lot with Southcenter Boulevard just north of Strander Boulevard. A sidewalk will be constructed on the north side of Strander Boulevard between 58th Avenue S and Andover Park W. To improve pedestrian safety. sidewalks also will be constructed along the mall frontage on Andover Park W. These sidewalks will provide access to the proposed bus pullout at Baker Boulevard. Pedestrian facilities connecting the mall entrances with the adjacent streets are also desired by the city. In particular, connections between the 61st Avenue S /Strander Boulevard intersection are desired to facilitate pedestrian access between Southcenter Mall and the Target Center. A new connection from the east side of the mall to Andover Park W is desired to facili- tate pedestrian access to the proposed bus pullouts. A pedestrian connection also will be devel- oped on the west side of the mall, connecting the mall with Southcenter Parkway. 89348.50/89348581 The TRANSPO Group, Inc. Page 55 MITIGATING MEASURES As discussed in the preceding analyses, the proposed expansion project will not sig- nificantly impact traffic operations or safety in the vicinity of the shopping center. The City of Tukwila does, however. have several transportation improvements planned for the area which would further enhance traffic flow in the area. One alternative would be to assess the project applicant a "fair share" of these pro- posed improvements based on the project's percentage of forecast traffic volumes for each intersection or roadway section. This process would result in the city collecting funds for several longer range projects. An alternative approach would be for the applicant to fund a larger portion of one or two projects that would directly offset the largest of the potential traffic impacts of the pro- posed shopping center expansion. In order to offset the potential impacts of the proposed expansion, it is recommended that the project applicant direct their mitigation toward pro- viding left -turn channelization and signalization at the intersection of Andover Park W and Baker Boulevard. The proposed channelization improvements should be designed to conform with the city's plans to ultimately widen Andover Park W to five lanes. The applicant also is working with Metro Transit and the city to construct bus pullouts along Andover Park W to replace the existing bus zone at the mall entrance. As part of the city's plans to widen Andover Park W to five lanes, the applicant will be required to dedicate right of way and construct frontage improvements on the west side of the road. The frontage improvements will include sidewalks. A pedestrian connection also will be required between the mall's east entrance and the proposed bus zone at Andover Park W /Baker Boulevard. In order to reduce conflicts along Andover Park W. north of Strander Boulevard, the existing post office driveway should be closed. The southernmost driveway which provides access to the bank could be restricted to right -in /right -out movements to reduce conflicts with southbound traffic queues on Andover Park W. To improve pedestrian safety and circulation, the city will likely require construction of sidewalks on the north side of Strander Boulevard between Andover Park W and the Doubletree Motel. A stairway will be developed to provide pedestrian access between the 89348.50/893485R1 The TRANSPO Group, Inc. Page 56 Doubletree Motel and Southcenter Parkway. The stairway will provide pedestrians wishing to cross Strander Boulevard safer access to the signalized intersections at Strander Boulevard/ Southcenter Parkway. A walkway will also be developed between the mall's west entrance and Southcenter Parkway. Providing a direct access from 61st Avenue S into the shopping center is not rec- ommended at this time. The extension would require split signal phasing and a loss of the existing overlapping of left and right -turn phasing. These changes would likely result in longer traffic queues along 61st Avenue S increasing safety problems and delays at the 61st Avenue S /Southcenter Boulevard intersection. If the city proceeds with a potential widening of 61st Avenue S between Tukwila Parkway and Southcenter Boulevard, the addi- tion of the south leg may be more appropriate. Detailed operations analyses should be completed at that time. The widening and signalization of Andover Park W /Baker Boulevard (including the bus zone) and construction of frontage and pedestrian connections should improve traffic operations. safety. and pedestrian circulation in the vicinity of the project. These improve- ments to be provided by the applicant should more than offset the potential traffic impacts of the proposed expansion. 89348.50/89348581 The TRANSPO Group, Inc.

We offer the following comments as we discussed by phone this morning, in response to each item listed: A. Ground floor elevation is stated on page 19, section 6.4 of our report, to be about el. 28.5 (U.S.0 &G.S. datum), the same as the exisdng mall areas. We are not familiar with the NGV datum --7 B. No additional fill is anticipated (i.e., for raising the grade level) for reasons given on page 19, Section 6.4 of our report. C. Impact of past fill over the entire Southcenter site is summarized on pages 8 and 9, Section 6.2 of our report. The proposed project is not expected to change this impact on the surrounding areas and facilities. D. Potential future settlements and downdrag loads on pile foundations are discussed on page 11, section 6.3.3 of our report. Seattle • Everett • Fairbanks • Anchorage • St. Louis PRESIDENT: Earl A.

City of Tukwila Public Works 6300 Southcenter Blvd. Tukwila, WA 98188 SUBJECT: PROPOSED MERVYN'S DEVELOPMENT - WATER SYSTEM REOUIREMENTS Dear Ron: In response to your request, we have identified the requirements put forth in the 1985 Comprehensive Water System Plan and Draft 1990 Comprehensive Water System Plan Update for the area east of the Southcenter Shopping Mall, along Andover Park West. It is our understanding that there is a 100,000 square foot commercial development proposed for this area. As indicated on the attached copy of Minimum Design Criteria taken from the 1983 Comprehensive Water System Plan the minimum required fire flow for commercial buildings within the City is 2,000 gpm, with case by case studies recommended for major buildings. Case by case studies are recommended for those buildings which would probably require flows greater than the required minimum. No changes to this minimum requirement have been proposed in the Comprehensive Water System Plan Update which we are currently working on. Although determining fire flow requirements of any proposed development will ultimately be the responsibility of the City Fire Marshall, the Comprehensive Plan and, subsequently, the. "Public Works Water Construction and Development Standards" have been developed as guidelines for determining minimum pipe sizes required to meet the minimum flow requirements mentioned above. The 1983 Comprehensive Plan indicates the need for a minimum 10 -inch line on. Andover Park West in order to accommodate any future development in this area. As indicated on the enclosed copies, the City's "Development Standards" support this recommendation by requiring that: "All extensions, additions, changes or alterations to the City water system shall be consistent with the Comprehensive Plan" (page 3); and, "Minimum commercial, industrial or multiple family unit water mains shall be minimum of ten inches (10 ") in diameter for looped and twelve inches (12 ") in diameter for non - looped systems or per the size required by the City's Comprehensive Water Plan, whichever is greater." (Page 5). 320 Second Avenue South, Kirkland, Washington 98033 -6687 • Phone 822 -2525 • FAX: (206) 822 -8758 Mr. Ron Cameron, P.E. City of Tukwila April 18, 1991 Page Two In summary, the hydraulic analysis prepared as part of development of the Comprehensive Water System Plan indicated the need for a minimum 10 -inch line along Andover Park West in order to meet minimum fire flow requirements of the area. We believe this recommendation to be accurate and consistent with the City's goals for overall water system development in the Southcenter area and therefore, recommend that the City implement the Comprehensive Plan recommendation as stated. If you have any questions, or require further analysis of the area, please let us know. Sincerely, HORTON DENNIS & ASSOCIATES, INC. Martin L. Penhallegon, P. President MLP /sew Enclosures Horton Dennis & Associates, Inc. • Consulting Engineers & Surveyors • Kirkland, Washington ::RIETRQ$ Municipality of Metropolitan Seattle • Exchange Building • 821 Second Ave. • Seattle, WA 98104 -1598 April 16, 1991 Mr. Tom Schmitz, Director of Engineering Jacobs, Visconsi & Jacobs Company 25425 Center Ridge Road Cleveland, Ohio 44145 -4122 Dear Mr. Schmitz: I'm sending you this letter to confirm Metro's position regarding our agency's financial participation in the proposed project involving improvements to Andover Park West adjacent to Southcenter Mali in Tukwila and the subsequent relocation of the Metro bus zone inside the Mall. Metro has long been interested in relocating the Southcenter Mall bus zone to another convenient location as it is becoming more difficult to operate transit buses through the Mall's parking lot. Since a proposed retail expansion of Southcenter Mall, operated by the Jacobs, Visconsi & Jacobs Company (JVJ) will severely restrict future transit access through the parking lot, the relocation of the bus zone is necessary. It is my understanding that agreement has been reached between JVJ, the City of Tukwila, and Metro to undertake a joint project to upgrade Andover Park West in the vicinity of Baker Boulevard, located immediately to the east of the Southcenter Mall. The first phase of this project will consist of the design and construction of a traffic signal at the Andover Park West /Baker Boulevard intersection. The next phase of the project will consist of the design and construction of a northbound and southbound bus pullout at this intersection, which would enable Metro to discontinue use of the existing Southcenter Mall bus zone. Since a traffic signal at the Andover Park West /Baker Boulevard intersection is essential for transit riders who would be transferring between buses and crossing the street to access the Mall, Metro will commit to 100% of the cost of this project element, which is estimated at up to $120,000. My understanding is that the city of Tukwila will bill Metro for the signal improvements. The subsequent project element would be the construction of the two bus pullouts including adjacent sidewalks and footings for passenger waiting shelters. Metro will commit to 100% of the cost of this project element, which is estimated at up to $110,000. Metro agrees that JVJ will bill Metro for this element of the project. Our understanding of JVJ's in the overall project is as follows: (APR.1 719911 CITY OF TUKWILA PLANNING DEPT. Mr. Tom Schmitz April 16, 1991 Page Two o Lead role in managing the design and construction of the two bus pullouts. o Deliver necessary right -of -way to the City of Tukwila for the pavement portion of the southbound bus pullout. o Provide the necessary easements for the sidewalk and shelter footings located at the southbound bus pullout. Coordinate the design and construction of the Andover Park West /Baker Boulevard traffic signal with. the City of Tukwila. Among the major issues yet to be resolved are the specific urban design elements of the two bus pullouts, right -of -way acquisition for the northbound pullout, and improvements to the pedestrian connection between Andover Park West and Southcenter Mall. We have always felt that pedestrian access between the southbound bus stop and the east side of the shopping center is the key to customer acceptance of this project as well as our future success in boosting transit ridership to Southcenter. Metro's expectation is that JVJ will construct a covered, wheelchair - accessible sidewalk connection between the Mall and Andover Park West as part of the project, since Metro is unable to fund improvements located on private property. We feel that this project is an excellent example of public - private sector cooperation to achieve common objectives. When completed, these improvements will also tie into the City of Tukwila's plans to widen and upgrade Andover Park West between Tukwila Parkway and Strander Boulevard. My staff and I look forward to working with JVJ and the City of Tukwila to assure the successful completion of this project. rely Eric Gleaso Acting Supe isor of Service Planning EG : dj o cc: Keith Masters, Manager, Southcenter Shopping Ctr., JVJ Co.

JVJ is proposing the use of 5' wide sidewalks in lieu of 6' wide sidewalks to minimize the impact on the number of existing parking spaces and to maximize the amount of landscape area. Head -in parking adjacent to sidewalk areas has also been modified to compact car dimensions to minimize negative impacts. CONFORMANCE TO CENTRAL BUSINESS DISTRICT (C.B.D.) SIDEWALK PLAN POLICY AND FINDINGS. ITEM II FINDING 'L' (Exhibit 'A', March, 1989) "Preserving existing development conformity with the Zoning Ordinance building setback, landscaping and parking standards is important to avoid unreasonable hardship on existing developments." POLICY 8 (Exhibit 'B', October 27, 1989) "Where a full width sidewalk is not feasible, the design will be adapted to the available space through joint planning by the Planning and Public Works Directors." POLICY 13 (Exhibit 'B', October 27, 1989) "Where sidewalks would interfere with existing parking, the sidewalk design will be modified by the Directors of Public Works and Planning to accommodate sidewalks. The need for pedestrian safety, parking, landscaping, and general conformance to municipal codes shall be balanced. However, pedestrian safety will be foremost. The City shall strive to preserve the existing number of parking spaces through restriping and use of compact stalls." LANDSCAPE AREA DISPLACED BY CONSTRUCTION OF SIDEWALKS REQUIRED UNDER ORD. #1516. JVJ believes that sidewalks and associated easements are valuable site amenities in the central business district which benefit the City of Tukwila and as such should be considered part of the required landscape /open space system. CONFORMANCE TO C.B.D. SIDEWALK PLAN 6 POLICY 12, (EXHIBIT 'B', OCTOBER 27, 1989) "Where the donation of easement or right -of -way for sidewalks in existing developments causes them to fall below City landscaping or building setback standards, the donated area shall be counted toward satisfying these requirements. This allowance shall cease upon building replacement, at which time all City ordinances shall be met. • • ITEM III STATUS AND CONDITION OF EXISTING SIDEWALKS ALONG TUKWILA AND SOUTHCENTER PARKWAY: JVJ believes that the existing sidewalks which are in place along Tukwila and Southcenter Parkway satisfy the requirements of the sidewalk ordinance. Construction of full width sidewalks at these locations is impractical due to topographic conditions and impact on existing parking. CONFORMANCE TO C.B.D. SIDEWALK PLAN POLICY AND FINDINGS: POLICY 9 (Exhibit 'B', October 27, 1989) "Existing sidewalks that are a minimum of four feet wide shall be deemed to be acceptable by the City. Sidewalks which are badly cracked, crumbling or uneven, as determined by the City Council, pursuant to RCW 35.68 and 35.69, shall be replaced in sections/blocks by standard size sidewalks at no cost to the City. POLICY 11 (Exhibit 'B', October 27, 1989) Curbline sidewalks should be provided whenever feasible. The Public Works Director shall determine the non - feasibility or curbline sidewalks based on factors such as the following: A. Impact upon existing utilities. B. Impact upon existing trees. C. Existing and proposed site grades. D. Public safety considerations. E. Impacts on existing parking. F. Convenience to pedestrian traffic. POLICY 8 (Exhibit 'B', October 27, 1989) "Where a full width sidewalk is not feasible, the design will be adapted to the available space through joint planning by the Planning and Public Works Directors." • • SOUTHCENTER MALL EXPANSION April 10, 1991 LIST OF MITIGATION ITEMS 1.

All extensions, additions, changes, or alterations to the City water system shall be consistent with the Comprehensive Plan. The Comprehensive Plan indicates the general location and configuration of the proposed system supply mains, inner -ties and loops. The exact location or configuration of the system may be modified or adjusted by the developer, provided the proposed system remains consistent with the overall concept of the Plan. All modifications to the Comprehensive Plan require specific approval by the Public Works Director. Water System Pressure All water mains shall be sized after a hydraulic analysis based on the required fire flow demands and pressure requirements. The system shall be designed to maintain a minimum pressure of 20 psi at ground level at all points in the distribution system under all conditions of flow. For most areas normal working pressure ranges between 150 psi and 160 psi.

MEMO FOR RECORD DATE: 12 Feb 91 FROM: Duane Griffin, Bldg Offl TO: File SUBJECT: Addition to Mali which will be connected to proposed new Mervyn's store (Conference call) Mike Johnson from Southcenter organization had previously requested a conference call, between myself and a group of people on their end, to discuss the Center Ridge Design ltr, signed by Larry Kuns, dtd 29 Jan 91. They wanted to get my reaction to their letter and address any concerns I had on the subject that I had previously discussed with Mike. The main question I have /had concerned the information I had previously received from Gerry Barbera, Northwest ICBO office, concerning the use of Chapter 56 for construction in malls that were built prior to the time the mall chapter came out in the UBC. He had told me that under normal conditions old malls hadn't been built with all the features required by the mall chapter, and therefore the mall chapter couldn't be used. Just prior to this telecon with Center Ridge people I took a floor plan up to Gerry to get his opinion, and based on his experience with malls and what he felt the intent of the code was we agreed that in this particular case using the mall chapter - ;might be appropriate if construction of the new mall area follows Chas 5i6! `completely and it can be verified that the smoke removal equipment required will not in any way allow smoke to migrate into or out of the area of the proposed addition to the mall. Based on the above, and my own research on the subject, I told the people on the conference call the following: 1. The new mall addition would have to include all the requirements of Chapter 56. They stated that was their intent. 2. I asked that the Architect of Rec9rd read UBC Sec 104(b) closely and submit in writing his reasoning and justification for determining that the addition or alteration will result in the existing building or structure being no more hazardous based on life safety, fire safety and sanitation than before such work was undertaken. They stated this would be done. 3. I pointed out that to comply with the mall chapter, Sec 5603(1), the new Mervyn's store could not be of Type III -N construction as they had shown on the information they had provided for the Pre -App meeting we previously had. The Center Ridge people said they have had a subsequent meeting with Mervyn's and everybody understands that the Mervyn's store will have to be a minimum of Type II -1 hour construction. 1 4. I stated that the entire new area, including the mall space directly in front of Penny's would have to have to meet the smoke removal and all requirements of Chap 56. Whoever answered me said that that hadn't been anticipated but if it was a requirement to get the project approved they would do it. 5. I pointed out that the trash container space located in the rated corridor behind spaces 336 and 340 is presently non- complying. They said this was a minor problem that they could remedy in their plans for this project. They wanted a verbal agreement that their exiting plan that the architect had submitted for review was all right. I stated I wouldn't do that and that it would be a part of the official plan check. process. At the end of the telecon they said they would send a memo of understanding of what , we discussed, including information from the Mechanical Engineer giving a narrative, with backup info, about how the smoke removal and other mechanical requirements of Chap 56 will be accomplished. They said they figured they could get the info to me within a week.

A filing fee in the amount of $225.00 has also been included. This submittal is made in compliance with the State Environmental Policy Act, Chapter 43.21C RCW, to assist the City in its determination of the existence of environmental impacts resulting from this project. Accompanying this checklist are the following additional materials for your review: o Traffic Impact Analysis, Dated December, 1990 o Geotechnical Report, Dated November, 1988 o Site Development Plan SK -4A o Parking Requirement Summary, Dated February 5, 1991 In addition to the above, we have enclosed a copy of our parking analysis worksheet which illustrates the parking required based on the existing Easement Restriction and Operating Agreements (ERO) in effect at Southcenter. The ERO parking requirements are based on the nationwide industry standard of 5 spaces /1,000 SF of gross leasable area (GLA). A review of the attached analysis reveals that after the planned expansion is implemented a minimal amount of excess parking will be available on the site (7 parking spaces).

SUPPLEMENTAL SHEET FOR ALL PROJECT AND NON PROJECT PROPOSALS The objectives and the alternative means of reaching the objectives for a proposal will be helpful in reviewing the aforegoing items of the Environmental Checklist. This information provides a general overall perspective of the proposed action in the context of the environmental infor- mation provided and the submitted plans, documents, suppor- tive information, studies, etc. 1. What are the objective(s) of the proposal? To satisfy the demand for additional retail space and to meet the needs within the existing market place. 2. What are the alternative means of accomplishing these objectives? An alternative for satisfying the market demand for additional retail space is to develop a separate retail center elsewhere in the market; however, the addition of unconsolidated retail space elsewhere would increase traffic on public r rt roadway network (i.e., trips from one establishment . to the other and additional duplicate trips). The increased traffic generated under this alternative would result in negative impacts on the community as a whole. Increased demand on city safety services would also result if a separate facility was constructed. 3.

The parking analysis has been tabulated according to the existing and proposed land uses and lists the corresponding parking requirements needed to comply with Chapter 18.56 of the Tukwila zoning code. Calculations indicated on sheet 1 of 2 assume that all food service within the mall falls within the general shopping center category and has been calculated accordingly. Conversely, sheet 2 of 2 assumes that the 7,755 SF of food court leasable area will be interpreted as "fast food" and the parking calculations have been adjusted to reflect the high parking requirements. A total of 6,639 parking spaces are required under scenario No. 1 and 6 755 parking spaces are required under scenario No. 2. A total of_6.988 par e g spaces will be available at Southcenter after the proposed expansion. Therefore, in each case, an adequate parking supply will be provided. We will telephone your office on Thursday afternoon, January 24th to discuss the parking summary in more detail and to answer any questions you may have. Sincerely, JACOBS, VISCONSI & JACOBS CO.

The proposed expansion would be setback approximately 430 feet from the north property line (Tukwila Parkway). The perimeter landscape strips between the parking areas and streets would be preserved. New walkways would include the following and are shown on the site plan attached: 1. sidewalks between the parking lot and landscape strip adjacent to Andover Park West from Union 76 to the Firestone facility; 2. walkway along the Baker Street access to the new east -side mall entrance; 3. sidewalk between the parking lot and landscape strip adjacent to Strander Blvd; 4. walkway along the Strander Blvd. access to the mall; 5. walkway along the Southcenter Parkway access; 6. stairway from Southcenter Parkway to the Doubletree Inn site; 7. stairway from Tukwila Parkway to the north parking lot 8. color concrete pavers along the Baker St. /Andover Pk West crosswalks linking south and northbound bus stops. tPral y- er ie Area The total number of existing parking spaces is 7076. The proposal would include restriping the existing lot. The parking area within the dashed boundary (see Attachment No. 1.c.) would be restriped. The total number of parking spaces provided after restriping would be 6988. This amount exceeds required parking by over 300 spaces (total required: 6647). The loading area would be on the north side of Mervyn's and would be screened from view with a 9 -foot high wall. The wall would match Mervyn's exterior in color and material and would have trees and shrubs in an adjacent planter. Height /Scale The mall expansion would be one story. The new arched east entrance would be similar in design to the Rainier Food Court entrance on the mall's south side at a reduced scale. Mervyn's would be two stories. Much of the second story would be recessed (see Attachment No. 2.b) TABLE OF CONTENTS INTRODUCTION 1 Project Description 1 Study Purpose 1 EXISTING CONDITIONS 7 Street System 7 Traffic Volumes, Levels of Service, and Warrant Analyses 9 Traffic Safety 20 Planned Transportation ,Improvements 24 FUTURE CONDITIONS WITHOUT PROJECT 27 FUTURE CONDITIONS WITH PROJECT 32 Trip Generation 32 Trip Distribution and Assignment 34 Forecast Traffic Volumes and Traffic Operations Impacts 34 Traffic Safety 44 MITIGATING MEASURES 46 LIST OF FIGURES 1.

The purpose of this study is to identify any potential adverse transportation - related impacts and to identify measures which may be required to mitigate the project impacts. Project Description As shown in Figure 1. Southcenter Mall is located in the southeast quadrant of the I -5 /I -405 interchange. Jacobs, Visconsi, Jacob is proposing to add a fifth major depart- ment store and some additional mall shops to the existing center. The expansion would include an 82,940- square foot (sf) department store and additional mall shops with a total of 21,446 gross square feet of leasable floor area (gsfla). The proposed expansion is planned for the northeast side of the mall, as shown in Figure 2. This expansion would increase the shopping center from just over 1,190,000 gsfla to 1,294,852 gsfla. In addition to the shopping center, the Southcenter site includes several fringe developments. These developments include a post office, movie theater, ser- vice station, and bank, totaling 37,393 sf. Including these fringe developments, the total site would include 1,332,245 gsfla including the 104,386 gsfla expansion. An existing 100,000 gsf motel located in the southwest portion of the Southcenter site is not included in the floor area calculations. A total of 6,662 parking spaces will be available on the Southcenter site, exclusive of the 326 parking spaces for the motel. The overall parking ratio with the expansion would be 5.0 parking spaces per 1,000 gsfla of floor area, exclusive of the motel parking spaces. Study Purpose The study area and specific traffic analyses presented in this report were identified through meetings and phone conversations with Mr. Ron Cameron, City of Tukwlla Engineer. The initial meetings and analyses occurred in late 1989 when an initial expansion plan was being proposed by Southcenter Mall. Those plans have been revised into the cur- rent proposal. Recent discussions with Mr. Cameron confirmed and updated the study 89348.00 The TRANSPO Group, Inc. Page 1 North Reproduced with permission grated by THOMAS BROS. MAPS.

Page 6 EXISTING CONDITIONS Street System Southcenter Mall is located in the southeast quadrant-of the I -5 /I -405 interchange. These freeways have on and off -ramps which facilitate traffic flow to /from the shopping center and other commercial developments in the vicinity of the mall. Figure 4 shows the other major streets in the immediate vicinity of the mall. Each of these facilities is briefly described below: • Strander Boulevard is a five -lane arterial on the south side of the shopping center. It provides east -west traffic flow between Southcenter Parkway and the West Valley Highway (SR 181) east of the site. In the immediate project vicinity, traffic signals are provided at its intersections with Southcenter Parkway and Andover Park W. A traffic signal has recently been installed at the intersection of Strander Boulevard and 61st Place S in conjunction with the recently developed Target Center on the south side of Strander Boulevard. • Southeenter Parkway is a five -lane north -south arterial adjacent to the west side of the shopping center. It provides access to Southcenter and many other commercial developments south of the mall. Its intersections with Strander Boulevard, Klickitat Drive, and the I -5 northbound off-ramp are signalized. • Klickitat Drive is a four -lane arterial connecting Southcenter Parkway with areas west of I -5. It provides access from the Southcenter area to southbound I -5. • Tukwila Parkway is a five -lane arterial paralleling I -405. It is used to connect to areas north of I-405 via 61st Avenue S (S -line bridge) and 68th Avenue S (T -line bridge). Traffic signals currently exist at its intersections with 61st Avenue S, the I -405 eastbound on -ramp, and Andover Park W. • Andover Park W is a four -lane north -south arterial on the east side of Southcenter Mall. It provides access to the industrial /commercial areas south of Strander Boulevard. 89348.00 The TRANSPO Group, Inc.

Page 8 • 61st Avenue 8 is a short four -lane arterial crossing I -405. It connects Tukwila Parkway with Southcenter Boulevard. Westbound traffic on I-405 uses 61st Avenue S to access the Southcenter commercial district. Traffic signals control traffic flow at both the Tukwila Parkway and Southcenter Boulevard intersections. • 8outhcenter Boulevard is a five -lane east -west arterial north of I -405. It con- nects to Interurban Avenue (SR 181) on the east and provides access to loca- tions west of I -5. Westbound I -405 has a ramp which connects to eastbound Southcenter Boulevard to provide access to the mall and surrounding commer- cial development. Access to eastbound I -405 is via Tukwila Parkway. Traffic Volumes, Levels of Service, and Warrant Analyses In order to provide a baseline for developing future traffic volumes and operations analyses, TRANSPO collected existing daily and peak hour traffic volume information from the City of Tukwila. These traffic volumes were supplemented with 1989 manual noon and PM peak hour turning movement counts conducted by Trafficount, Inc., and TRANSPO at all analysis intersections (see Figure 3). At some locations, 1987 and 1988 City of Tukwila counts were factored to estimate 1989 volumes. 1989 traffic volumes are summarized on Figure 5. As previously noted, a proposed expansion plan was being developed in late 1989. At that time, TRANSPO and Trafficount collected new manual traffic counts at study area intersections. In order to check on the adequacy of using the 1989 counts as a baseline for this traffic impact study, TRANSPO reviewed the City of Tukwila control counts for nearby intersections. Table 2 summarizes the comparisons. 89348.00 The TRANSPO Group, Inc.

Control counts at three of the live intersections decreased slightly between 1989 and 1990. These three locations are located adjacent to or west of the shopping center. Average daily traffic volumes at the intersection of Andover Park west at Pond increased by 11.0 percent between 1989 and 1990. The largest increases at that intersection occurred between July and November, reflecting the recent opening of the Target /Tukwila Pond Center south of Strander Boulevard. Inasmuch as the full traffic impacts of the Target /Tukwila Pond Center are included in the forecast traffic volumes, this increase does not invalidate the use of the 1989 traffic counts as a basis for the traffic analysis. An increase of over 7 percent in daily traffic volumes is reported for Interurban Avenue north of Southcenter Boulevard. This location could have been impacted by construction on I -405 or other external factors. Since this count location is more removed from the project study area, it was decided to continue to use the 1989 traffic counts as a basis for developing future traffic volumes. Based on the 1989 noon hour and PM peak hour turning movement counts, level - of- service analyses were conducted for all of the study analysis intersections. The analyses were conducted using the methodologies presented in the Highway Capacity Manual, Transportation Research Board, 1985. 89348.00 The TRANSPO Group, Inc. Page 11 Level of service for signalized intersections is defined in terms of delay. Delay is a ' measure of driver discomfort, frustration. fuel consumption. and lost travel time. Specifi- cally, level -of- service criteria are stated in terms of the average stopped delay per vehicle for a 15- minute analysis period. Delay is a complex measure and is dependent on a number of ' variables including the quality of progression, the cycle length, the green ratio, and the volume -to- capacity ratio for the lane group or approach in question. Table 3 shows the level -of- service criteria for signalized intersections from the Highway Capacity Manual. Table 3. Level -of- Service Criteria for Signalized Intersections Stopped Delay E 0 to 99 Very long delays F Less than 0 Failure - extreme congestion The results of the noon peak hour and PM peak hour levels of service are summa- rized in tables 5A and 5B, respectively. The detailed level -of- service worksheets are con- tained in Appendix A of this report. ' 89348.00 The TRANSPO Group, Inc. Page 12 Table 5A. Existing Levels of Service - Noon Peak Hour Reference Location' Signalized Intersection Existing Approach LOS1 Avg Delay 1 Strander BoulevardlSouthcenter Parkway Northbound C 23.2 Southbound C 18.3 Westbound CID 27.3 Overall C 21.4 2 Klickitat Drive /Southcenter Parkway Northbound B 12.2 Southbound C 17.5 Eastbound C 16.4 Overall B/C 15.1 Refer to Figure 3. All of the signalized intersections that were analyzed were found to currently operate at LOS D or better during the noon and PM peak hours. However, some of the approaches and specific traffic movements operate at lower levels of service as discussed below. Strander Boulevard/Southcenter Parkway During the noon peak hour, this intersection operates at an overall LOS C. Two turning movements are, however, calculated to operate at LOS D —the west -to -south left turns and the south-to -east left turns. During the PM peak hour, the intersection operates at an overall LOS D. The south- to -east left turns operate at LOS E, reflecting longer average delays for this movement. The longer delays result in some traffic queuing between this intersection and the intersection of Klickitat Drive and Southcenter Parkway. Westbound traffic also was observed to queue along Strander Boulevard blocking driveways to the motel entrances. On some of the signal cycles, northbound traffic queues from the intersection of Klickitat Drive and Southcenter Parkway reduced the effective capacity for some traffic movements at this intersection. This resulted in longer observed delays and worse levels of 89348.00 The TRANSPO Group, Inc. Page 13 a Table 5B.

Klickitat DrivelSouthcenter Parkway This intersection operates at an overall LOS C during both the noon and PM peak hours. During the noon peak hour, the east -to -north left turn operates at LOS D, while all other movements are LOS C or better. During the PM peak hour, the east -to -north left turn operates at LOS E with all other movements at LOS C or better. Due to the lack of coordination between the traffic signals at Klickitat Drive and Strander Boulevard, traffic queues develop between the intersections. These traffic queues reduce the potential capacity of the intersection, resulting in worse levels of service than calculated. 1 -5 Northbound Off -Ramp/ Southcenter Parkway During the PM peak hour. the eastbound and westbound approaches at this inter- section are calculated to operate at LOS D. with the northbound and southbound approaches operating at LOS B /C. Overall, the intersection operates at LOS C during the PM peak hour. Tukwila Parkway161 st Avenue S This intersection is calculated to operate at an overall LOS B during the PM peak hour. Longer delays exist for the east -to -north left turns and westbound thru traffic movements which operate at LOS D. The level of service at the intersection can worsen significantly when traffic queues from the intersection of Southcenter Boulevard and 61st Avenue S block the intersection. The traffic queues could be minimized with a signal interconnect between these two closely spaced intersections. 89348.00 The TRANSPO Group, Inc. Page 16 Southcenter Boulevard /61st Avenue S This intersection was calculated to operate at an overall LOS B/C during the PM peak hour. The eastbound thru and west -to -south left -tum movements operate at LOS D during the PM peak hour. Due to the close spacing of traffic signals on 61st Avenue S, the level of service of this intersection can worsen due to the potential for southbound traffic queues to extend back from the intersection of 61st Avenue S at Tukwila Boulevard. These traffic queues can block the east -to -south right turns and the west -to -south left-turn movements, resulting in longer delays at the intersection. PM peak hour levels of service were also calculated based on the 1989 traffic vol- umes for five unsignalized driveways to the shopping center. It should be noted that the level -of- service analyses were adjusted to reflect the increased number of gaps in the thru traffic on the major streets resulting from the multiple travel lanes in each direction and the effect of nearby traffic signals. Both the unadjusted and adjusted worksheets are included in Appendix A. In addition to the PM peak hour levels of service, traffic signal warrant analyses were conducted for each of these driveways. The warrant analyses were conducted using the 1989 baseline traffic counts. The warrant analyses worksheets are included in Appendix B and were conducted based on the criteria outlined in the Manual of Uniform T rafflc Control Devices (MUTCD), FHWA. The following summarizes the resulting level -of- service and warrant analyses for the five unsignalized driveways. Southcenter Parkway/ S 159th Street (West Theater) The west theater entrance consists of a single 15 -foot wide exit lane intersecting with the four -lane Southcenter Parkway. A left -turn acceleration lane is provided on Southcenter Parkway to provide refuge for vehicles making the west -to -south left turn. Based on the adjusted traffic volumes, the west -to -south left turn is calculated to operate at LOS D/E during the PM peak hour, which is consistent with field observations. The west -to -north right -turn movement is relatively minor with fewer than 30 vehicles during the PM peak 89348.00 The TRANSPO Group, Inc. Page 17 hour. This right turn also operates at LOS D/E due to the existing shared lane configu- ration. If a separate right -turn lane were provided, the right -turn movement would operate at LOS A Current traffic volumes at the intersection meet two of the traffic volume warrants presented in the MUTCD. The intersection meets the criteria for Warrant 2 (interruption of continuous traffic) and Warrant 9 (four -hour volumes). Warrant 1 (minimum vehicular volume) is met seven hours of the day. just under the eight hours required to satisfy the warrant. Tukwila Parkwayl 59th Avenue S (North Theater) This intersection currently operates at LOS D or better for all movements. LOS D is calculated for the north -to -west left turn which impacts fewer than ten vehicles during the PM peak hour. Northbound right turns are calculated to operate at LOS A during the PM peak hour. Observations indicate longer delays than calculated due to traffic queues extending west of the Tukwila Parkway /61st Avenue S intersection. These traffic queues also result in a worse than calculated LOS A for the west -to -south left turns. The resulting delays for the west -to -south left turn are minimized since many drivers do not block the driveway. allowing the left turns to be made safely. This intersection meets traffic signal Warrants 2 (interruption of continuous traffic) and 8 (combination of warrants). However the majority of the minor street traffic (northbound) are right turns which would not be greatly improved by the installation of a traffic signal. Andover Park WIS 159th Street (Union 76 Entrance) All movements at this intersection currently operate at LOS B or better during the PM peak hour. The east -to -north left turns would operate at LOS C. and the east -to -south right turns would operate at LOS A if two exiting lanes were provided. 89348.00 The TRANSPO Group, Inc. Page 18 The existing traffic volume and lane configuration would meet the MUTCD criteria for Warrants 1 (minimum vehicular traffic) and Warrant 9 (four -hour volume). However. given the good level of service and proximity to the signalized intersection of Andover Park W at Tukwila Parkway, a signal at this driveway would probably not be needed nor desirable. Andover Park W /Baker Boulevard This four -leg intersection currently operates at LOS C or better during the PM peak hour. The majority of the traffic exiting the shopping center makes a right turn, which operates at LOS A. Westbound traffic at the intersection also operates at LOS A for right turns and LOS C/D for the thru /left -turn movements. This intersection does not currently meet traffic signal warrants as identified in the MIJTCD. The intersection volumes are, however, within ten vehicles of meeting the criteria for Warrant 9 (four -hour volume). Andover Park W (north of Strander Boulevard) Three minor driveways are located along this section of Andover Park W. The southernmost driveway provides access to a bank, the center driveway serves the post office. and the northernmost driveway provides access to a tire store and to the outer parking areas of the shopping center. During peak travel periods. southbound traffic queues from the intersection of Strander Boulevard /Andover Park W blocks one or more of these driveways. Traffic exiting the driveways is delayed due to these queues. Observations indicated only minor traffic volumes at each of these driveways, primarily due to the traffic queues. The north -to -west left turns entering these driveways also are delayed by the southbound traffic queues. Vehicles stopped to make this left turn were observed to block northbound thru traffic resulting in delays to thru traffic. 89348.00 The TRANSPO Group, Inc. Page 19 Strander Boulevard 158th Avenue S (just east of Doubletree Motel) This intersection currently operates at LOS D/E for the south -to -east left turns exiting the shopping center. In 1989, only 33 vehicles were counted making this movement during the PM peak hour. The majority of traffic exiting the shopping center via this drive- way make a right turn onto westbound Strander Boulevard. The right -turn movement is calculated to operate at LOS A. However, westbound traffic approaching the intersection of Strander Boulevard at Southcenter Parkway may queue beyond this driveway during peak travel periods resulting in a worse level of service. The traffic signal warrant analysis shows that the existing traffic volumes and road- way geometry meet Warrant 2 (interruption of continuous traffic), Warrant 9 (four -hour volume), and Warrant 11 (peak hour volume). As previously noted, the majority of the traf- fic using this driveway is orientated to /from the west, reducing the actual need for a signal for exiting vehicles. The City of Tukwila has proposed a new arterial in the 58th Avenue S corridor. The four -lane facility would connect Strander Boulevard with S 168th Street. This improvement project is currently scheduled for construction no earlier than 1995. The proposed align- ment for 58th Avenue S would intersect Strander Boulevard 100 to 150 feet west of this driveway. Since 58th Avenue S would be an arterial, it also will likely be signalized. At such time that the city moves forward with the 58th Avenue S project, it would be desirable to relocate the existing stopping center access drive to form a four - legged signalized inter- section. If such a realignment is not possible, this driveway would likely be restricted to right -in /right -out movements to minimize traffic conflicts. Traffic Safety 'Traffic accident data provided by the City of Tukwila were analyzed to identify any existing safety problems which could be impacted by increases in traffic associated with the project. Accident data were obtained for the three -year period between August 30. 1986 to August 30. 1989. These data were originally collected for the 1989 traffic analysis. Dis- cussions with the City Engineer indicated that analysis of 1990 accident data would not significantly alter the evaluation of safety issues in the study area; therefore, 1990 data are not included. The number of accidents for each of the three years ending August 30 are summarized in Figure 6. 89348.00 The TRANSPO Group, Inc.

Page 21 In general. most intersections and roadway sections in the immediate vicinity of the project have a relatively low occurrence of accidents, relative to the existing traffic volumes. The highest accident occurrences are found at the intersection of Strander Boulevard and Southcenter Parkway. A large number of accidents are also found on Strander Boulevard just east of Southcenter Parkway. Other signalized intersections which have relatively high accident occurrences are Klickitat Drive at Southcenter Parkway, Tukwila Parkway at 61st Avenue S, and Southcenter Boulevard at 61st Avenue S. The only unsignalized inter- sections with relatively high accident histories are the intersection of Andover Park W at Baker Boulevard and the intersection of Strander Boulevard with 58th Avenue S (adjacent to the Doubletree Motel). Strander Boulevard/Southcenter Parkway Eight (8) of the 21 accidents reported by the city during the three -year period at the intersection of Strander Boulevard and Southcenter Parkway were rear end accidents involving northbound vehicles on Southcenter Parkway. The other accidents at the inter- section showed no major patterns and included a variety of angle. approach turns, sideswipes, and collisions with parked vehicles or other fixed objects. Strander Boulevard East of Southcenter Parkway The section of Strander Boulevard adjacent to the Doubletree Motel has experienced a large number of accidents over the three-year period. Of the 31 accidents reported by the City of Tukwila, 24 involved vehicles entering or leaving one of the motel driveways. In all but 1 of the 24 accidents, the traffic from the motel driveways collided with westbound traffic on Strander Boulevard. Many of these accidents are likely due to the westbound traffic queues which block the driveways and restrict sight distance for exiting and entering vehicles. Three rear end and one sideswipe collisions also were recorded, all involving westbound traffic on Strander Boulevard. The other three accidents during the three -year period were right -angle collisions involving traffic accessing or egressing driveways on the south side of Strander Boulevard. 89348.00 The TRANSPO Group, Inc. Page 22 Klickitat DrivelSouthcenter Parkway A total of 18 accidents were recorded at this intersection over the three -year analy- sis period. The most predominate type of accidents were rear -end collisions. Of the seven rear end accidents, five involved northbound vehicles, with one each involving southbound vehicles. The northbound rear -end collisions likely result from the close proximity of the Southcenter Parkway /Strander Boulevard intersection and traffic queues between the intersections. The other accidents included a variety of sideswipes (4), right angle (4), and colli- sions with fixed objects (3). No pattern was detected in these accidents which involved traffic from differing directions and times of day. Tukwila Parkway 158th Avenue S Of the 21 accidents recorded at this intersection over the three -year analysis period, 9 were of the rear end variety, 5 sideswipe, 3 right angle, and 4 others. Of the rear end accidents, the majority involved eastbound or southbound traffic. The sideswipe and right angle accidents involved a variety of approaches and movements at the intersection with no particular pattern. Southcenter Boulevard 161st Avenue S Eight (8) of the 14 accidents recorded at this intersection during the three -year time period were right angle accidents involving the north -to -west left -turn and eastbound thru traffic. The remaining accidents include three sideswipe and three rear end collisions, with half involving northbound vehicles on 61st Avenue S. Many of the accidents at this intersection are likely related to the short distance between intersections along 61st Avenue S which limits the distance that drivers have to react to changing traffic conditions. 89348.00 The TRANSPO Group, Inc. Page 23 Andover Park W /Baker Boulevard A total of 14 accidents were recorded at this intersection over the three -year time period. Five of the accidents involved southbound traffic in collisions with westbound traf- fic on Baker Boulevard. Four other accidents involved southbound thru vehicles and north -to -west left turning vehicles. Three rear end accidents also were reported, all involv- ing northbound vehicles. No sight distance problems were observed that would create a safety hazard at the intersection. As previously noted, traffic volumes at this intersection would not meet warrants for installation of a traffic signal. Strander Boulevard 161st Avenue S (Adjacent to Doubletree Motel) A total of 13 accidents were recorded at this intersection over the three -year period ending August 30, 1989. Eight of the accidents involved westbound thru traffic and east - to -north left turns. Three of the remaining five accidents were angle accidents involving south-to -east left turns and westbound thru traffic. A rear end and sideswipe accident also involved westbound vehicles. Many of the accidents at this location appear to be related to the westbound traffic queues which extend from the intersection of Strander Boulevard and Southcenter Parkway. Planned Transportation Improvements The City of Tukwila has several transportation improvement projects proposed for the vicinity of Southcenter Mall. Table 6 and Figure 7 summarize the projects within the immediate study area. It should be noted that many of the projects listed are not currently funded. These projects were considered in developing the traffic mitigation program for the proposed expansion project. In addition to these projects, the City of Tukwila recently completed work on a long - range transportation improvement needs study. Draft recommendations for that study also were used in developing the traffic mitigation program. 89348.00 The TRANSPO Group, Inc. Page 24 Table 6.

Page 25 FUTURE CONDITIONS WITHOUT PROJECT In order to asses the potential traffic impact of the proposed shopping center expan- sion, future baseline traffic volumes were developed and analyzed without the project. A forecast year of 1993 was selected to reflect the anticipated completion and occupancy of the proposed expansion. The 1993 without project traffic forecasts were developed in a two -step process. First, existing traffic volumes were increased by 1 to 2 percent per year based on PM peak- hour traffic trends in the area between 1986/87 and 1989. A 1 percent annual growth rate was utilized along Southcenter Parkway, Strander Boulevard, and Klickitat Drive. The 2 percent annual growth rate was utilized along 61st Avenue S, Andover Park W, Southcenter Boulevard, and Tukwila Parkway. In addition to the background growth rate. the 1993 without project traffic volumes include traffic that will be generated by the Target /Tukwila Pond Center. The Target/ Tukwila Pond Center is a 160,000 square foot shopping center recently constructed just south of Southcenter Mall. Traffic volumes and assignments for that project were obtained from the traffic impact analysis supplied by the City of Tukwila. This process results in a 5 to 6 percent annual growth rate on Strander Boulevard adjacent to Southcenter Mall, with lower growth rates on other streets in the study area. The resulting 1993 without project traffic volumes are shown in Figure 8. Tables 7A and 7B summarize the resulting levels of service for comparison purposes.

CD SOUTHCENTER MALL EXPANSION Rgure 8 1993 WITHOUT PROJECT TRAFFIC VOLUMES The Transpo' Group 89348.00 The TRANSPO Group, Inc. Page 30 The increase in traffic volumes without the project did not result in any significant changes in the levels of service for signalized intersections. All signalized intersections that were analyzed are forecast to continue to operate at an overall LOS D or better during the noon and PM peak hours. As described in the Existing Conditions section of this report, some traffic movements may operate at lower levels of service than shown in Tables 7A and 7B. The relative increase in overall vehicle delay at an intersection is, however, indicative of the impact of the increased traffic volumes. All but two critical movements at unsignalized intersections also will operate at LOS D or better. The south -to -east left turn from the shopping center driveway located just east of the Doubletree Motel (58th Avenue S) is forecast to worsen from an existing LOS D/E to a LOS E. This decrease in level of service is related to the increase in traffic along Strander Boulevard associated with the Target /Tukwila Pond Center. Based on the 1993 without project traffic forecast, this poor level of service will impact fewer than 50 vehicles exiting this driveway during the PM peak hour. The west -to -south left turns from S 159th Street (W Theater driveway) onto Southcenter Parkway also are calculated to operate at LOS E during the PM peak hour. The existence of the left -tum acceleration lane, which was not accounted for in the level of ser- vice calculation, will probably provide a better forecasted level of service for these left turns. 89348.00 The TRANSPO Group, Inc.

Page 33 Trip Distribution and Assignment The project trips were distributed and assigned to the study area street system. The distribution was based on a review of a 1986 survey of shoppers at the mall. The informa- tion presented in the market survey was collaborated through a review of the trip tables developed by the Puget Sound Council of Governments for their regional traffic models. The results of the distribution analysis are summarized in Figure 9. The distribu- tion results in 25 percent of the new project traffic orientated to /from the northeast in the I -405 corridor, 24 percent to /from the southeast, 14 percent to /from the southwest. 19 percent to /from the northwest, and 13 percent to /from the north. Five (5) percent were distributed to the local area immediately south and east of the center. Figure 10 summarizes the project traffic assignment in the immediate study area. Assignments to specific driveways took into account existing travel patterns, access to regional transportation facilities, and the location of the proposed expansion within the shopping center. Forecast Traffic Volumes and Traffic Operations Impacts The resulting project traffic assignment was superimposed on the forecast 1993 without project traffic volumes to obtain the 1993 with project traffic forecast. Figure 11 summarizes the resulting 1993 with project forecast. The largest increase in traffic associated with the proposed expansion project will be found on Andover Park W south of Baker Boulevard. During the noon peak hour, the pro- ject would add approximately 30 vehicles in each direction on this section of roadway. The project would add 25 vehicles in each direction during the PM peak hour. Due to the variations in the on -and -off ramps to I -5 and I -405, traffic increases on Klickitat Drive, 61st Avenue S, and Southcenter Boulevard will vary by direction of travel. During the PM peak hour, the project will increase traffic volumes on westbound Klickitat Drive by 30 vehicles, but will only increase eastbound volumes by 15 vehicles. 89348.00 The TRANSPO Group, Inc.

This extension would provide direct access from 61st Avenue S into the shopping center, eliminating the need for traffic to make a right turn onto westbound Tukwila Parkway and a subsequent left turn into the site via 59th Avenue S (north theater driveway). The extension would also eliminate the reverse movements for traf- fic exiting the shopping center. As previously described. these movements result in weaving maneuvers and traffic queues which add to congestion in the vicinity of the two intersections. Developing the extension without widening 61st Avenue S and /or Tukwila Parkway would eliminate the use of the existing overlapping of signal phases for complementary left and right turn movements.

Appendix A includes the unadjusted and adjusted worksheets. Refer to Figure 3. use of split phasing for all approach legs reducing the capacity of the intersection. Split phasing could be required because left turns would need to share travel lanes with thru traffic resulting in LOS F conditions and associated potential safety problems. The split phasing and reduction of the overlap phasing would likely create extensive traffic queues and increase delays on the S -line bridge which would also impact traffic operations at the intersection of 61st Avenue S at Southcenter Boulevard. The addition of the south approach to the intersection would, however, reduce the existing traffic queues along Tukwila Parkway by closing the existing driveway. The reduced traffic queues should enhance thru traffic flow along 'Tukwila Parkway. The draft recommendations of the City of Tukwila Transportation Plan includes a project to widen 61st Avenue S (including the bridge) between Southcenter Boulevard and Tukwila Parkway. This widening would allow a separate southbound thru traffic lane to provide direct access to Southcenter and still allow separate left and right -turn lanes and more storage capacity between Tukwila Parkway and Southcenter Boulevard. If and when the city pursues the widening of 61st Avenue S. the potential addition of the south approach should be reevaluated. A short-term project to improve traffic operations at this and other nearby intersec- tions would be the interconnection of the traffic signals along 61st Avenue S (S -line bridge). A signal interconnect system would enhance traffic flow by reducing traffic queues which block the adjacent intersection. The city has a project to pursue interconnect systems in its Six -Year Transportation Improvement Program. Southcenter Parkway (Klickitat Drive to Strander Boulevard) The city is considering long -range projects to widen Southcenter Parkway, Strander Boulevard, and Klickitat Drive. Based on the analyses completed for this project, these projects will not be required prior to 1993. Planning and funding for the projects should, however, continue based on the city's long -range transportation plans. The proposed expansion project would have minimal impacts on traffic volumes and operations along this section of roadway. As previously discussed, traffic queues between the intersections of Klickitat Drive and Strander Boulevard result in longer delays and 89348.00 The TRANSPO Group, Inc. Page 42 worse levels of service than calculated and reputed in this study. The traffic queues may be able to be reduced by interconnecting these two traffic signals. Other adjacent signals also could be included in the interconnect system to enhance general traffic flow along Southcenter Parkway. Strander Boulevard at 58th Avenue S (Doubletree Motel) During the PM peak hour, the south -to -east left -turn movements at the unsignal- ized intersection of Strander Boulevard and 58th Avenue S (just east of the Doubletree Motel) are forecast to operate at LOS E/F with the proposed expansion project. Fewer than 55 vehicles are forecast to make this turn during the PM peak hour. Although a traffic signal is warranted at the intersection, most of the exiting traffic makes a right turn onto westbound Strander Boulevard. These right turns would not greatly benefit from signalization. A traffic signal wlll likely be installed when the city completes a new four -lane arterial between Strander Boulevard and S 168th Street. It would be desirable to realign this driveway (100 to 150 feet west) to align with the new arterial and future traffic signal. If a traffic signal is installed, it should be interconnected with the existing signal at Strander Boulevard and Southcenter Parkway to minimize the impacts of traffic queues on operations at the two intersections. Southcenter Parkway at S 159th Street (West Theater Entrance) Left turns from S 159th Street (west theater driveway) onto Southcenter Parkway are also forecast to operate at LOS E during the PM peak hour. The forecast level of service does not, however, accurately reflect the provision of the left -turn acceleration lane at the intersection. As discussed in the Existing Conditions section of this report, this location currently meets the criteria for installation of a traffic signal. Installation of a traffic signal at this location does not appear to be appropriate. given the availability of the left -turn acceleration lane and minimal accident occurrence over the past three years. 89348.00 The TRANSPO Group, Inc. Page 43 Widening of the west theater driveway to provide separate right and left -turn lanes would reduce delays for the right turning vehicles. Since fewer than 35 vehicles are fore- cast to make this right turn, widening of the driveway also is not necessary. All other unsignallzed intersections are forecast to operate at LOS D or better during the PM peak hour. The project would not result in a decrease in level of service at any of the intersections that were analyzed. Traffic Safety The proposed expansion will increase traffic volumes on the streets in the project vicinity. The increase in traffic could lead to a slight increase in accidents in the area. Although there is no reliable method for forecasting increases in accidents, it is likely that the increase in accidents at any location would be proportional to the increase in traffic volumes. The project's greatest impact on safety would likely occur at the intersection of Andover Park W and Baker Boulevard. This intersection will serve as a major entrance to the new department store. The addition of left -turn lanes and /or a traffic signal would help reduce the potential safety problem. It should be noted. however. that although a traffic signal is not currently warranted at this intersection (based on 1989 counts), a signal will likely be warranted in the near future. The project would add only minimal traffic to the three driveways located on Andover Park W immediately north of Strander Boulevard. Additional thru traffic along Andover Park W would. however. add to the traffic queues. resulting in longer delays and possibly increasing the number of accidents. Options include closing one or more of the driveways to minimize the number of conflict points and to discourage traffic using these driveways. Specifically, the center driveway which serves the post office could be closed. This driveway is located just north of the driveway to /from the bank and therefore would not result in a significant increase in travel distance for post office users. Another option would be to restrict traffic flows at the bank driveway to right -in- right -out only. This restriction would not impact a significant amount of traffic since many drivers currently avoid making left turns at this driveway because of traffic queues. The 89348.00 The TRANSPO Group, Inc. Page 44 right -in /right -out restriction would reduce the impacts of southbound traffic queues on traffic exiting this driveway. The city has proposed widening Andover Park W to provide a continuous two -way left - turn lane between Tukwila Parkway and S 180th Street. Construction of a two -way left-turn lane would help facilitate traffic flow and safety along this section of Andover Park W. The increase in traffic volumes resulting from the proposed expansion will not, however, trigger the need for this widening. 89348.00 The TRANSPO Group, Inc. Page 45 MITIGATING MEASURES As discussed in the preceding analyses, the proposed expansion project will not sig- nificantly impact traffic operations or safety in the vicinity of the shopping center. The City of Tukwila does, however, have several transportation improvements planned for the area which would further enhance traffic flow in the area. One alternative would be to assess the project applicant a 'fair share" of these pro- posed improvements based on the project's percentage of forecast traffic volumes for each intersection or roadway section. This process would result in the city collecting funds for several longer range projects. An alternative approach would be for the applicant to fund a larger portion of one or two projects that would directly offset the potential traffic impacts of the proposed shopping center expansion. In order to offset the potential impacts of the proposed expansion, it is recommended that the project applicant direct their mitigation toward providing left-turn channelization and future signalization at the intersection of Andover Park W and Baker Boulevard. Signalization of this intersection is not currently warranted; however, with the general increases in traffic in the area. signal warrants will likely be met by the time the proposed expansion is complete. The proposed channelization improvements should be designed to conform with the city's plans to ultimately widen Andover Park W to five lanes. In lieu of improvements at the intersection of Andover Park W and Baker Boulevard, the applicant could contribute funds for the proposed traffic signal interconnect system. The proposed interconnect system should help improve traffic flow between closely spaced intersections in the area, thereby reducing delays and potential safety problems. In partic- ular, contributions toward establishing signal interconnect systems along 61st Avenue S and Southcenter Parkway would offset the impacts of the proposed expansion. In order to reduce conflicts along Andover Park W, north of Strander Boulevard, the existing post office driveway should be closed. The southernmost driveway which provides access to the bank should be restricted to right -in /right -out movements to reduce conflicts with southbound traffic queues on Andover Park W. 89348.00 The TRANSPO Group, Inc. Page 46 Providing a direct access from 61st Avenue S into the shopping center is not rec- ommended at this time. The extension would require split signal phasing and a loss of the existing overlapping of left and right -turn phasing. These changes would likely result in longer traffic queues along 61st Avenue S increasing safety problems and delays at the 61st Avenue S /Southcenter Boulevard intersection. If the city proceeds with a potential widening of 61st Avenue S between Tukwila Parkway and Southcenter Boulevard, the addition of the south leg may be more appropriate. Detailed operations analyses should be completed at that time. 89348.00 The TRANSPO Group, Inc.

TUKWILA, WASHINGTON 1.0 INTRODUCTION This report presents the results of our geotechnical engineering studies for the foundation design of the Additional Mall Shops at the Southcenter Shopping Center, Tukwila, Washington. Borings were previously completed at the site and for adjacent facilities in 1961, 1966, and July 1988. Our engineering analyses, conclusions, and recommendations are based on these previous field boring explorations and our earlier experience in the vicinity of the project site, including our previous reports pertaining to adjacent facilities, and construction pile driving records in the vicinity. This work was accomplished in general accordance with our proposal letter dated May 27, 1988. Authorization to proceed with our work was given by letter dated June 10, 1988 from Center Ridge Design Services, Inc., together with the executed revised agreement dated July 12, 1988. The report includes a brief description of the project and scope of our work, together with our conclusions and recommendations, based on our engineering studies and analyses. It is our understanding that no structural engineer has yet been assigned to this project; therefore, our approach has included some assumptions and considers several alternative pile types for foundation support. 2.0 PROJECT DESCRIPTION 2.1 Location and Site The proposed Additional Mall Shops are to become a part of the Southcenter Shopping Center, Tukwila, Washington, about 3 miles west of Renton and approximately 20 miles south of Seattle, Figure 1. The mall shops are to be 1 SHANNON & WILSON. INC. W- 4978 -01 located immediately adjacent to the north end of the existing J.C. Penney building at the northeast corner of the shopping center. A paved parking lot currently occupies the proposed mall shops area. The elevation of the site is approximately +27 feet M.S.L. (U.S.C.&G.S. datum), see Figure 2. 2.2 Project We presently assume that the proposed Additional Mall Shops will have the same general structural configuration as the existing mall area. No basement is planned. The proposed building dimensions are on the order of 150 feet x 180 feet. It is assumed that the column bay spacing will be approximately 24 feet x 24 feet, the same as the existing mall area. Live loads are assumed to range from 100 to 125 psf. Due to the very soft compressible nature of the subsurface soils in the general depth range of 15 to 40 feet below the present ground surface, the building must be supported on deep foundations. 3.0 SCOPE OF WORK A great deal is known about the general subsurface conditions, design, and construction of the Southcenter Shopping Center. Because of the previous boring explorations, engineering studies, testing, and pile driving experience in the immediate vicinity of the site, it was our opinion that no additional borings or laboratory tests were necessary in connection with this report. Engineering studies have been directed primarily toward building foundation requirements, including recommended pile types, capacities and estimated lengths, lateral resistance of piles, driving criteria, estimated settlements, and test pile program. Other items addressed in our report include floor support, earthwork, seismic design considerations, lateral earth pressures, drainage and backfill requirements, and construction considerations. Pertinent information from previous site explorations, laboratory and field test data, engineering studies, and construction at Southcenter has been reviewed and 2 SHANNON & WILSON, INC. W- 4978 -01 utilized extensively in the present study. Where specifically applicable, such information has been summarized or extracted from previous reports and is included as a part of the present report. Previous reports, prepared by Shannon & Wilson, Inc., for the Southcenter Shopping Center Corporation, and for Center Ridge Design Services, Inc., that are particularly applicable to the Additional Mall Shops foundation design are as follows: 1) "Report on Foundation Investigation for the Shell Structure, Southcenter Shopping Center, Tukwila, Washington," August 5, 1966. 2) "Report on Foundation Investigation, J.C.

Borings H -7 and H -8, completed in 1961 and reproduced in our August 5 and August 22, 1966 reports, together with boring B -137 from our August 5, 1966 report, form the basis of. the Generalized Subsurface Profile A -A', Figure 3, of this report. Boring H -8, together with boring C -4 from our August 29, 1988 report, are the bases for Generalized Subsurface Profile B -B', Figure 4. Generalized Subsurface Profile C -C', Figure 3 SHANNON & WILSON. INC. W- 4978 -01 5, has been developed from borings H -7 and C -1, the latter also from our report of August 29, 1988. The logs of these borings, together with others in the vicinity, have been reproduced and are included in Appendix A. 5.0 SUBSURFACE CONDITIONS 5.1 Geologic Setting 5.1.1 Regional The Southcenter Shopping Center lies on the floor of the north -south trending Duwamish Valley. The floor of the valley ranges from 10 to 25 feet above sea level and in nature is broad and quite flat. The Green River presently occupies a portion of this valley, flowing northward through the valley approximately 1/2 -mile east of the site. The Duwamish Valley lies in a much larger region known as the Puget Sound lowland. This lowland is a major linear depression (structural and topographic) that trends northward between the Olympic Mountains on the west and the Cascade Range on the east. Tertiary sedimentary and igneous rocks making up the Puget Group are exposed in relatively few places within the lowland; where encountered they are generally well- weathered, fractured, and occasionally faulted. Pleistocene (glacial age) sediments consist predominantly of drift deposited during repeated invasions of the Puget Sound lowland by ice lobes that originated in the coastal mountains of British Columbia. At least four glacial drift sheets and their related deposits are recognized in the lowland. 4 SHANNON & WILSON, INC. W- 4978 -01 5.1.2 Local The site of the present study is relatively flat, and has an average elevation of +27 feet. It is underlain at relatively shallow depth by rocks belonging to the Puget Group. Hard silt or "siltstone" was recognized in several borings in the vicinity. Rocks associated with the Puget Group outcrop immediately to the north of the site and on both sides of the Duwamish Valley. Materials overlying bedrock consist of estuary, stream, and glacial deposits of tills, sands, gravels, silts, clays, peats, and organic clays. During Pleistocene time the general site was buried under about 3,000 feet of glacial ice during four periods of glaciation. During the last period, the Vashon ice sheet scoured the valley floor in places to bedrock and deposited glacial till in and along the borders of the valley during its advance and retreat, leaving the mid - valley rock floor far below sea level. After the recession of the Vashon ice, waters of Puget Sound occupied the Duwamish Valley as indicated by the marine shells in most of the borings. Subsequently, the Green and White River deltas, combined with the estuary deposits, filled the valley to its present level. In 1906 the White River was diverted to the south. Estuary deposits of late Pleistocene to Recent age are principally peat, silt, and clay and are present as back -swamp deposits. Since the general site is located along the western edge of the valley, there is a general slope to the east of both the bedrock and glacial till subsurface. Thus the depth to firm material generally increases in an easterly direction at the site. 5 SHANNON & WILSON, INC. W- 4978 -01 5.2 General Stratigraphy The general subsurface conditions encountered at the proposed project site are generalized on the subsurface profiles shown on Figures 3 through 5. More detailed subsurface conditions are shown on the individual boring logs. Based on the subsurface conditions encountered as shown on the profiles and individual boring logs, the subsoils can be divided into five units: 1) Fill, 2) soft to medium stiff organic Silt and Peat, 3) medium dense to dense Sand and Gravel, with shells and organics, 4) dense to very dense Sand and Gravel, with shells and organics, and 5) Hard layers of sandy Silt. The stratigraphy generally consists of 14 to 18 feet of surface Fill, which was previously obtained from borrow areas in the vicinity of the site. The Fill is underlain by 15 to 30 feet of interbedded compressible strata of organic clayey Silt and Peat. Beneath the compressible stratum there is generally a stratum of medium to dense Sand and Gravel with some shells and organics. This stratum is variable in thickness, ranging from 10 to 20 feet thick within the site boundaries. Beneath the medium dense Sand and Gravel stratum is a stratum of dense to very dense Sand and Gravel varying from 10 feet to more than 50 feet in thickness at H -8. This stratum contains some cobbles and boulders at some locations. The bottom unit is a hard, fine, sandy Silt (rock -like in some borings). 5.2.1 Fill It is our understanding that the site fill was obtained from borrow areas in the hillside generally west of the site area. The in -situ soils in the borrow areas consisted of strata of silt and clay, sand, and gravel. Based on the Standard Penetration Resistance (N) obtained in the fill, it is generally well- compacted. The N- values are predominantly less than 30. However, they range from as low as 8 at boring H -7 to as much as 26 at boring H -8. The N- values are normally higher in the upper portion, possibly due to drying and more systematic compaction during placement. 6 SHANNON & WILSON. INC. W- 4978 -01 5.2.2 Soft to Medium Stiff Organic Silt and Peat The soils classified as organic silt consist predominantly of soft to medium stiff, organic, blue -gray to brown, clayey silts with some fine sand and gravel. Some of the silts exhibit a livery texture. The water content ranges from 25 to 71 percent. The peat consists predominantly of soft to stiff fibrous material which generally contains a considerable amount of silt or clay. The water content varies from 25 to 215 percent. Standard Penetration Test N- values for these materials range from 1 to 13 blows per foot. 5.2.3 Medium Dense to Dense Sand and Gravel The somewhat silty sand and gravel encountered underneath the site is part of an alluvial deposit co,itaining some sea shells and organics and was found to be generally wet. The water content ranges from 4 to 21 percent. Standard Penetration Resistances range from 15 to 50 blows per foot. 5.2.4 Dense to Very Dense Sand and Gravel The dense to very dense slightly silty sand and gravel also contains shells and some organics. The Standard Penetration Resistances are greater than 30 blows per foot and range up to 50 blows for 2 inches. 5.2.5 Hard Layered Silt The hard silts encountered here are predominantly weathered, distorted layers of hard, sandy silt. This material generally exhibits "rock- like" characteristics being somewhat cemented. The water content ranges from 4 to 30 percent with an average of 18 percent. 7 SHANNON & WILSON, INC. W- 4978 -01 5.3 Groundwater Conditions Groundwater levels were observed during drilling at previous borings and some were measured following drilling. Based on the results of observation and measurement during drilling for adjacent proposed Department Store No. 5, groundwater levels range in depth from approximately 16 to 40 feet below the surface. Boring C -1 was monitored for 5 days. At the beginning of the fifth day the water level was at 5.5 feet, along with borings C -4 and C -5. Borings H -7 and H -8 show the groundwater at the surface in 1961. 6.0 ENGINEERING STUDIES AND RECOMMENDATIONS 6.1 General Based on the subsurface conditions encountered in the current borings and our review of the previous borings, pile load test results, and the pile driving records for the existing J.C. Penney and Shell Structure (mall) buildings, engineering studies were conducted to develop recommendations for 1) building foundation support, 2) floor support, 3) site preparation and earthwork, 4) seismic design criteria, 5) lateral earth pressures, 6) drainage considerations, and 7) other related geotechnical work. Architectural and structural plans were not available during preparation of this report. Certain assumptions were made, therefore, for our engineering studies. We have also assumed that the design would be accomplished under the provisions of the 1985 Uniform Building Code. 6.2 Settlement of Site The Southcenter site is largely underlain by soft compressible material as described under Section 5.0, Subsurface Conditions. Since the proposed Additional Mall Shops completely overlie the soft material, this facility must be supported by deep foundations; hence, structural loads will not 8 SHANNON & WILSON, INC. W- 4978 -01 induce significant compression of the compressible material. However, the weight of the existing 15 to 20 -foot thick fill placed on the site in the early 1960's has caused considerable settlements up to the present time and will lead to additional settlements largely occurring during the next 10 to 15 years. The mechanism of compression of organic materials, such as those underlying the site, is not clearly understood; however, it is known that in general, the rate of compression of such materials, under a given load, decreases ,exponentially with time. Therefore, if the magnitude of applied load and consequent settlement at some elapsed time are known, reasonably accurate settlement predictions can be formulated. Based on the understanding that the fill over the site was placed between the summer of 1959 and the summer of 1962, and from the limited information available from site surveys and sequence of filling operations, the above method of calcu- lation indicates at least 2 to 6 inches of additional settlement could occur over the major portion of the site during the next 10 to 15 years. Because the deposit of soft compressible material is somewhat erratic, both in character and in thickness, the final settlements should also be expected to be erra-Lic. The anticipated settlement of the site will generate certain problems which should be included in the design considerations for the building. The most significant of these problems are as follows: 1) downdrag loads will be induced on foundation support piles due to negative skin friction between the settling soils and piles. The magnitude of downdrag loads will be discussed in subsequent sections; 2) utilities and service lines extending beneath the building, should be anchored to the structure. The settlement of the fill will require that utilities services outside the building be articulated to allow for the estimated movements. This will necessitate special consideration in the design of utilities connections to the building; 3) provisions for storm water drainage of the ground should also be designed in anticipation of the projected site settle- ments; and 4) void spaces occurring under the floor slab as the fill settles may require special provisions to prevent the accumulation of noxious gases produced by decay of organic matter in the underlying organic silt and peat. 9 SHANNON & WILSON. INC. W- 4978 -01 6.3 Building Foundation Support 6.3.1 Foundation Support Schemes As indicated in the previous Section 6.2, in our opinion, the compressible soils underlying the site are still settling under the existing fill load. Additional settlements could be greater than 2 inches in the next 10 years. We, therefore, recommend that the proposed Additional Mall Shops structure be pile supported. Our engineering studies on pile foundations include 1) pile types, 2) downdrag and bearing strata, 3) penetrations and capacities, 4) lateral resistances of piles, 5) pile driving equipment and criteria, 6) estimated settlements, and 7) test piles. 6.3.2 Pile Types The existing J.C. Penney building and mall corridor areas located immediately south and west of the proposed building site are supported by mandrel- driven Raymond pipe step -taper piles. Pile tip elevations along the north edge of the mall corridor area (glass wall, Figure 2) range from -84 to -114 feet, west to east. Existing pile tip elevations bordering the west edge (glass wall) of the proposed Additional Mall Shops range in elevation from -65 to -87 feet, north to south. If the proposed mall structure loads are similar to those of the existing mall structure, based on the subsurface conditions encountered in the borings, we recommend that prestressed concrete piles and closed -end steel pipe piles be considered as foundation piles in addition to Raymond step -taper piles. The recommended pile types and sizes are thus as follows: • 16.5 -inch octagonal prestressed concrete piles 10 SHANNON & WILSON, INC. W- 4978 -01 • 16- inch - diameter steel pipe piles driven closed -end with a flat bottom plate • Raymond step -taper piles with a 12 -1/4 -inch tip diameter (Shell No. 2) 6.3.3 Downdrag and Bearing Strata As previously mentioned, additional settlements greater than 2 inches could occur under the existing fill load in the next 10 years. Case histories on In 1967, six pile pull -out tests were performed on Raymond step -taper piles with 12 -1/4 -inch tip diameter and 14- inch - diameter steel pipe piles, for evaluating the downdrag in the fill and compressible soil layers. The test results are summarized as follows: Pile Type Raymond Step -Taper Tip Dia. 12 -1/4 ", Butt Dia. 16 -3/8" Raymond Step -Taper Tip Dia. 12 -1/4 ", Butt Dia. 16-3/8" Measured Downdraq Load 1967 Pull -out Tests Prebored Approx. Penetration Thru Fill Measured Downdraq (feet) (tons) 40 40 No 120 Yes 55 Steel Pipe 14" Dia. 40 No 60 11 SHANNON & WILSON. INC. W- 4978 -01 Negative skin friction or downdrag load could be reduced by coating piles with bitumen or by driving piles into predrilled holes. Our studies indicate, however, that a satisfactory pile foundation could be obtained without reducing negative skin friction for prestressed concrete or steel pipe piles. For Raymond step -taper piles, predrilling through the fill layer will be required to reduce the downdrag load, in our opinion. 6.3.4 Pile Penetrations and Capacities The estimated penetrations and capacities for 16.5 -inch octagonal prestressed concrete piles, 16 -inch 0.D. steel pipe piles (driven closed - end), and Raymond step -taper piles, and for subsurface conditions encountered in borings H -7, H -8, and C -4 are summarized as follows: Estimated Pile Penetrations and Capacities Est.

Based on the results listed above, the recommended allowable design compression loads are: 12 SHANNON & WILSON. INC. W- 4978 -01 • 75 tons for 16.5 -inch .octagonal prestressed concrete piles • 75 tons for 16 -inch 0.D. steel pipe piles driven closed -end • 70 tons for Raymond step -taper piles with a 12 -1/4 -inch tip diameter Using the estimated total tension capacities listed above and a factor of safety of 3, the recommended allowable design tension or uplift loads are: • 50 tons for 16.5 -inch octagonal prestressed concrete piles • 40 tons for 16 -inch 0.D. steel pipe piles driven closed -end • 50 tons for Raymond step -taper piles with a 12 -1/4 -inch tip diameter Pile compression and tension capacities may be increased by 33 percent for seismic loading conditions. In addition, the pile tip elevations shown above are estimated and provided for design purposes only. As noted, both pipe piles and the mandrel- driven, Raymond step -taper piles are expected to penetrate at least 15 to 20 feet deeper than the concrete piles, at profiles represented by borings H -7 and H -8. The production pile order length should be determined after evaluating the results of test piles as discussed in Section 6.3.8. 6.3.5 Lateral Resistance of Piles Lateral loads acting on the structure may be resisted by the passive earth pressure against the pile caps and grade beams, the frictional resistance developed between the sides of the pile cap, and the lateral resistance provided by the vertical piles. The frictional sliding resistance at the base of the pile cap should be ignored, in our opinion, because a pile - supported structure may not transmit load directly to the soil beneath the pile cap. We recommend that passive earth pressures developed from compacted granular fill against the pile caps and grade beams be estimated using an equivalent fluid weight of 180 pounds per cubic foot (pcf). This value applies to 13 SHANNON & WILSON. INC. W- 4978 -01 soils above the groundwater table and assumes that the pile caps and grade beams are founded at least 2 feet below the lowest adjacent grade and includes a factor of safety of 2.0. We further recommend that a frictional coefficient of 0.4 be used to estimate the frictional resistance between the sides of the pile cap and the soils. Lateral resistance analyses of a single 16.5 -inch octagonal concrete pile and a 16 -inch 0.D. steel pipe pile were made using the subsurface profile conditions represented by borings H -7 and H -8. The lateral resistance of each pile was analyzed using a beam on elastic foundation computer program for both fixed and free -head conditions. The results of deflection, moment, and shear in the piles at various depths are presented in Figures 6 through 9. Since this computer program is based upon an elastic analysis, the deflection, moment, and shear are directly proportional to the magnitude of the horizontal loads. As shown in Figures 6 and 8, under a fixed head condition and a horizontal load of 5 kips, the lateral deflections are 0.17 and 0.19 inches for 16.5 - inch concrete and 16 -inch steel pipe piles, respectively. Assuming that the allowable pile cap movement is 0.5 -inch, these piles may resist a horizontal load of about 15 kips. If additional lateral resistances are required, batter piles may be considered for resisting lateral loads. Horizontal subgrade reaction constants and strength parameters of soils used in our analyses are listed under the heading "Soil Data" in the respective Figures 6 -9. The horizontal subgrade reaction constants were reduced by a factor of 1/2 for repetitive loading. 6.3.6 Pile Driving Equipment and Criteria Fixed lead pile driving equipment is recommended to drive the piles. The use of hanging or swinging leads is not recommended unless they are constructed so that they can be held in a fixed position during driving 14 SHANNON & WILSON. INC. W- 4978 -01 operations. Leads should be of sufficient length so that the use of followers will not be necessary. An air -, steam -, or diesel - powered hammer may be used for driving the recommended 16.5 -inch octagonal concrete and 16- inch - diameter steel pipe piles. If diesel - powered hammers are utilized, a hammer with a rated energy ranging between 35,000 and 70,000 ft -lbs. per blow with a ram weight of not less than 6,600 lbs. is recommended. The Delmag D30 -32 diesel hammer meets the aforementioned requirements. Should a steam- or air - powered hammer be used, it should have a minimum rated energy of 40,000 ft -lbs. per blow, but not more than 60,000 ft -lbs. per blow. For the recommended Raymond step - taper piles, the commonly used Vulcan No. 80C differential- acting hammer having a rated energy of 24,450 ft -lbs. per blow would be suitable, based on our previous experience with piles. installed at J.C. Penney's and the existing mall area. All pile driving equipment should be designed, constructed, and maintained in a manner suitable for the work to be performed on this project. If, in the opinion of the Engineer, the driving equipment is inadequate or deficient, he may recommend to the owner that it be removed from the job site. All costs for remobilizing, removing, or replacing such equipment should be at the Contractor's expense. The Contractor should furnish the manufacturer's specifications and catalog for the hammer proposed. As a minimum, the Contractor should furnish the information required on the Pile and Driving Equipment Data Sheet, shown in Table 1, seven days in advance of his scheduled pile driving. It has often been difficult to estimate the energy delivered by diesel hammers in the past. The Saximeter recently developed by Pile Dynamic, Inc., can be used to record hammer strokes and provide an estimate of the driving energy of diesel hammers. We recommend that a Saximeter be used should the Contractor select a diesel hammer. 15 SHANNON & WILSON, INC. W- 4978 -01 In order to establish the driving criteria for test and production piles, the Wave Equation Analysis for pile driving is recommended. This method includes an evaluation of driving stresses so that an appropriate pile- driving hammer size can be selected to obtain the desired pile capacity without damage to the pile. This analysis also determines the ultimate pile capacity for a given driving resistance. Piles should be driven to at least twice the design load as determined by the Wave Equation Analysis of Pile Driving (WEAP). Results of wave equation analyses for the recommended 16.5 -inch octagonal prestressed concrete, and 16- inch - diameter by 3/8 -inch wall steel pipe piles, 75 feet long and driven with a Delmag D30 -32 diesel hammer, are presented on Figures 10 and 11. Based on the results shown, the final driving resistance required for the 16.5 -inch concrete pile driven with a Delmag D30 -32 diesel hammer with a hammer stroke of about 7 feet (an average hammer energy of 45,500 ft -lbs. per blow) would be about 80 blows per foot Figure 10), for an assumed design load of 75 tons and a downdrag load of 80 tons. For an average hammer energy of 49,000 ft -lbs. per blow, the required final driving resistance for the 16- inch - diameter steel pipe pile would be 84 blows per foot (Figure 11) under an assumed design load of 75 tons and a downdrag load of 60 tons. Wave equation analyses were not performed for Raymond step -taper piles in this study. Should Raymond step -taper piles be selected for foundation support, wave equation analyses should also be conducted prior to test pile driving. It is recommended that all piles be driven to the estimated pile tip elevations as shown in Section 6.3.4, and to the required final driving resistance as determined by the Wave Equation Analysis for the last foot. If the required final driving resistance is not reached near the estimated pile tip elevations, driving may be stopped for a minimum of 12 hours and then redriven until the specified driving resistance is achieved. As an alternate, the pile may be driven further to obtain the required final driving resistance. Should the required minimum driving resistance be 16 SHANNON & WILSON. INC. W- 4978 -01 achieved before piles reach the estimated tip penetrations, the piles should be driven to at least 1.5 times the specified driving resistance. The Wave Equation Analysis curves provided in this report are for design purposes only, using the assumed hammer and pile cushion data as shown on the figure. The data were selected based on our past experience. Driving criteria for test and production piles should be determined by a similar Wave Equation Analysis using data for the actual hammer- cushion -pile combination to be used in driving the piles. 6.3.7 Estimated Settlements of Pile Foundations Based on the assumed design and downdrag loads, the estimated pile tip elevations, and the subsurface conditions encountered, total and differential settlements on the order of 0.4 -inch to 0.6 -inch are estimated. About 0.2 -inch to 0.3 -inch of the estimated settlements would be due to elastic compression of the piles. Since the piles are to be driven into very dense or hard soil strata, in our opinion, the settlements would occur almost simultaneously with load application. 6.3.8 Test Pile Program The previously estimated pile tip elevations were based on the subsurface conditions encountered in the current and previous borings. For the prestressed concrete pile, a predetermined length is generally required in order to minimize the chance of splicing or cutting off the pile. For the steel pipe and Raymond step -taper piles, it would also be helpful to have better defined pile lengths prior to ordering production piles. As presented in the previous Section 6.3.4, the estimated pile tip elevations may differ 15 to 20 feet within the proposed building area. Thus, prior to ordering production piles, we recommend that at least 7 test piles be driven to better define the length of piles required. The approximate locations of the 7 driven test piles are shown on Figure 12. Should the Additional Mall 17 SHANNON & WILSON, INC. W- 4978 -01 Shops be constructed before the proposed Department Store No. 5 to the north, then two additional test piles should be driven, one in each north corner of the new structure area. The test piles may be driven within the closest pile cap in each case. In 1967, six pile pull -out tests and three pile compression load tests were performed on Raymond step -taper piles and steel pipe piles at the adjacent existing Southcenter building sites. We have used these load test results for our studies on pile penetrations and capacities. In our opinion, static pile load tests will not be necessary for this project. However, we recommend that dynamic measurements with the Goble pile analyzer be performed on the recommended driven test piles located at the two south corners of the building, and at the center of the north edge. Goble's pile driving analyzer should be used for the initial driving. The dynamic measurements should continue until the driving resistance reaches about 12 blows per inch or when the pile penetration is about 6 inches above the estimated pile tip elevation. The measurements should be taken again after pile driving has been discontinued for a minimum of 12 hours. The results of the driving tests, the pile driving analyzer, and the Wave Equation Analysis of Pile Driving will be used to determine the pile lengths and develop the pile driving criteria for the production piles. Test piles can be used as production piles to carry design loads, provided that they meet the specified driving criteria. 6.3.9 Monitoring Pile Driving All pile driving should be monitored by taking a continuous driving record for each pile. For this purpose, the Contractor should be required to paint a line across the pile in 1 -foot increments. During redrive, additional increments between the 1 -foot marks may be required. 18 SHANNON & WILSON. INC. W- 4978 -01 The pile driving record should be complete. The form should have spaces to record hammer stroke, blows per minute, time, date, and reasons for delays, and other pertinent information. In addition, the record should include tip elevation, driving criteria, and initials of inspectors making final - acceptance of the pile. The Saximeter developed by Goble Rausche Likins, Inc., should be used to estimate the energy of diesel hammers. The pile driving records should be reviewed by Shannon & Wilson, Inc., on a daily basis. For this purpose, we recommend that an engineer from our office who is familiar with this type of project be assigned to assist in construction monitoring. All driven piles should be checked for possible heave. The heave data should be provided to the Engineer who will determine if redrive is required. 6.4 Floor Support It is our assumption that the ground floor of the Additional Mall Shops will be at about elevation 28.5 feet. This is the same as the other existing mall areas. The contour lines shown in Figure 2 indicate that the average existing ground elevation at this site is approximately 27.0 feet. In order to reach the final floor elevation of 28.5 feet, the required fill and concrete floor thicknesses would be about 1.5 feet. Thus, additional dead loads due to the weight of fill and concrete slab may be greater than 200 psf. This dead load plus the anticipated live loads of 100 to 125 psf would make the total additional loads acting on the existing ground to be about 300 to 350 psf. This additional load would likely cause undesirable total and differential settlements, estimated to range from 1 to 3 inches. This, together with the general site settlement already occurring, may make the performance of the floor slab unsuitable. Therefore, we recommend that the ground floor consist of a structural floor slab, appropriately supported by grade beams or equivalent and tied into the pile foundations. 19 SHANNON & WILSON. INC. W- 4978 -01 6.5 Site Preparation and Earthwork We anticipate that the existing pavement will be removed at all footing and pile cap locations for pile installation. The existing pavement outside the footing areas may be left in place. We recommend that clean granular fill be used to raise the grades prior to casting the structural slab. All fill to be placed around the pile caps and grade beams, on -grade floors, pavements, or other areas where settlements are to be minimized, should be a structural fill. Based on our previous experience and the gradations obtained for several representative samples for other projects, most soils encountered at the project site would not be suitable for use as structural fill. Thus, most structural fill should be imported. Imported structural fill should consist of well - graded sand or sand and gravel. It should contain not more than 20 percent fines (material passing the No. 200 sieve, 0.075 mm), based on the 3/4 -inch fraction, and should have a maximum particle size of 3 inches. It should be free of organic matter, and its moisture content should be within -3 percent, but not more than 2 percent above the optimum for compaction. The fines should be non - plastic. If fill is to be placed in wet weather no matter .what time of year, structural fill should have a maximum limit of 5 percent non - plastic fines. Structural fill should be placed in uniform lifts and compacted to a dense, unyielding state, and to at least 95 percent of its Modified Proctor maximum dry density (ASTM Designation: D- 1557 -70, Method C or D). The thickness of structural fill layers before compaction should not exceed 8 inches when heavy compaction equipment is used and 4 inches for hand - operated mechanical compactors. 20 SHANNON & WILSON. INC. W- 4978 -01 6.6 Seismic Design Criteria 6.6.1 Characteristic Site Period It is anticipated that the seismic design of the facility will be based upon an equivalent static method of analysis as outlined in the Uniform Building Code. This particular procedure requires information on the characteristic site period of the underlying soils as input in this structural evaluation. It is recommended that a characteristic site period ranging from 0.8 to 1.2 seconds be used for the seismic design of the structure. Our evaluation of the characteristic site period is based upon the materials encountered in the previous borings drilled at and adjacent to the site, and from our experience of the engineering characteristics and geology of the anticipated underlying subsurface soils. This range of site period values was computed in accordance with the Uniform Building Code Standard #23 -1. As an alternative to the characteristic site period evaluation method, the structural design may be performed using an S- factor oi-,1.2 to account for site - structure resonance. This S- factor corresponds to S2 soil type as described in Section 2312 of the 1985 Uniform Building Code. 6.6.2 Ground Stability In our opinion, the medium dense to dense sands which underlie the site below elevation -10 feet (MSL) will not liquefy as a result of an earthquake similar in size to events typically used for the design of buildings in the Puget Sound area. However, the soft clayey silts and peats underlying the building site between elevations +10 and -10 may possess very little strength during earthquake ground shaking. Accordingly, piles which penetrate this stratum may undergo large lateral deformations during an earthquake. The piling for the structure should be designed to account for potentially large ground displacements within this layer of soft soils. This would necessarily require additional confining steel to be placed in 21 SHANNON & WILSON. INC. W- 4978 -01 concrete piling to minimize potential spalling of the pile. It is recommended that lateral analyses be performed on the piles to determine the distribution of shear, moment, and deflection of the piles to facilitate the design of the foundation elements. The results of the lateral soil- - structure resistance analyses of piles are presented in Section 6.3.5. 6.7 Drainage and Backfill Requirements Any parts of the structure which are to extend below the ground floor elevation such as an elevator shaft or small basement for mechanical or other utility rooms, should have a peripheral subdrain system to protect the walls and floors from moisture and to avoid the build -up of hydrostatic pressures. Our recommendations for a subdrainage system and backfilling for any depressed facility areas are presented on Figure 13. As shown, backfill material within 18 inches of any basement walls should consist of drainage sand and gravel which is hydraulically connected to the subdrain system. The recommended 6 -inch layer of washed pea gravel beneath floor slabs should also be hydraulically connected to the subdrain system. Subdrains beneath floors may be required if seepage is encountered during excavation. The need for these should be evaluated and determined during construction. All backfill within a minimum horizontal distance of '5 feet from walls should be placed in loose lifts not exceeding 4 inches and compacted with a hand - operated vibrating plate. Heavy compactors should not be used near the walls to prevent increases in lateral pressure due to overcompaction. The remaining backfill should be placed in 6 -inch loose lifts and compacted with suitable compactors. The top 18 inches of the backfill should consist of relatively impervious materials to seal off, insofar as practical, surface water. Also, the final grade should have a gentle slope away from the wall to drain surface water. 22 SHANNON & WILSON, INC. W- 4978 -01 All backfill should be compacted to a density equal to at least 90 percent of the Modified Proctor Maximum dry density (ASTM Designation: D -1557) where some settlements are not objectionable and to at least 95 percent where settlements should be minimal. If footings and floors are located adjacent to the walls in backfill compacted to 95 percent minimum, total settlements approximately equal to 1/2 percent times the thickness of the fill could occur. If this settlement is excessive, floor slabs adjacent to the exterior walls should be provided with additional reinforcing steel. 6.8 Lateral Earth Pressures Against Permanent Structures The lateral earth pressure against a wall below grade would be dependent on the method of backfill placement, the type of backfill material, drainage provisions, and whether the wall is permitted to deflect laterally after or during placement of backfill. If the walls are allowed to deflect laterally or to rotate an amount equal to about 0.001 times the height of the wall, an active earth pressure condition would prevail and an equivalent fluid pressure of 35 pounds per cubic foot (pcf) is recommended for the design of walls. For rigid walls that are restrained from deflecting at the top, an at -rest earth pressure condition would prevail and an equivalent fluid pressure of 55 pcf is recommended. These pressures do not include the influence of groundwater. If drainage provisions are not included in the wall design, the lateral earth pressures should be increased to 80 pcf for the active condition and 90 pcf for the at -rest condition. The above values do not account for any surcharge loads near the walls, such as: heavy construction machinery, building equipment, or loads from footings placed in close proximity to the walls. An equivalent lateral pressure due to surcharge should be added to the recommended lateral earth pressures, where appropriate. 23 SHANNON & WILSON. INC. W- 4978 -01 7.0 LIMITATIONS The analyses, conclusions, and recommendations contained in this report are based on site conditions as they presently exist. We further assume that the previous exploratory test borings are representative of subsurface conditions throughout the site; i.e., the subsurface conditions everywhere between and below the explorations are not significantly different from those disclosed by the explorations. If, during construction, subsurface conditions different from those encountered in the previous explorations are observed or appear to be present beneath excavations, we should be advised at once so that we can review these conditions and reconsider our recommendations where necessary. If there is a substantial lapse of time between the submission of this report and the start of work at the site, or if conditions have changed due to natural causes or construction operations at or adjacent to the site, we recommend that this report be reviewed to determine the applicability of the conclusions and recommendations considering the changed conditions and time lapse. We recommend that we be retained to review those parts of the plans and specifications which pertain to earthwork and foundations to determine if they are consistent with our recommendations.
