We reviewed the environmental checklist and have the following comments. The checklist indicates that 9,000 cubic yards of "suitable" fill will be imported to the site. The use of fill material meeting the definition of demolition, inert, or wood waste under Section 100 Chapter 173 -304 WAC may require a solid waste permit from the local health department. Such materials include, but are not limited to concrete, asphalt, and stumpage. Pit -run gravel, natural solids, and screened /engineered fill are usually exempt from the solid waste permit requirements. If you have any questions, please call Mr. Kyle Dorsey of our Solid and Hazardous Waste Program at (206) 867 -7132. Sincerely, Donald J.

ENVIRONMENTAL CHECKLIST Purpose of Checklist: The State Environmental Policy Act (SEPA), chapter 43.2IC RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. Instruction for Applicants: This environmental checklist asks you to describe some basic information about your proposal. The City uses this checklist to determine whether the environmental impacts of your proposal are significant, requiring prepara- tion of an EIS. Answer the questions briefly, with the most precise infor- mation known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or. "does not apply ". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shore- line, and landmark designations. Answer these questions if you can. If you have problems, the City staff can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The City may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Use of checklist for nonproject proposals: Nonproject proposals refer to actions which are different or broader than a single site specific development project, such as plans, policies and programs. Complete this checklist for nonproject proposals, even though questions may be answered "does not apply." In addition, complete the supplemental sheet for nonproject actions (part D). For nonproject actions, the references in the checklist to the words "project," "applicant," and "property or site" should read as "proposal," °proposer," and "affected geographic area," respectively.

Suite 100 Bellevue, Washington 98005 -3464 (206) 643 -2002 SEn4 Fi EBASCO SITE TRAFFIC ANALYSIS TUKWILA, WASHINGTON FOR SABEY CORPORATION INTRODUCTION The Sabey Corporation is currently involved in the planning and design process necessary to remodel and expand the existing Ebasco office /industrial building in Tukwila, Washington. The existing building, located at the southwest corner of Andover Park East and Tukwila Parkway, is being proposed for conversion to an Eagle Home /Yard Improvement Center. The existing general office space on the north end of the building would remain as general office space. Corporate offices for Eagle Home Center would also be incorporated into the building modification and addition project. The existing building includes the following: EXISTING BUILDING GROUND FLOOR: NORTH SIDE GENERAL OFFICE SPACE OFFICE /COMPUTER LAB SPACE GENERAL LIGHT INDUSTRIAL* GROUND FLOOR SUBTOTAL MEZZANINE LEVEL: 24,500 SF 30,000 SF 46,500 SF 101,000 SF CORPORATE OFFICE FOR LIGHT INDUSTRIAL 19,600 SF LIGHT INDUSTRIAL 10,000 SF MEZZANINE SUB -TOTAL 29,600 SF TOTAL - EXISTING BUILDING 130,600 SF * Ebasco office space has been converted to a sportswear manufac- turing facility. 1 1 ...MAR 131990 PLANNING DEPT.

EXISTING CONDITIONS Street System Access to the Ebasco site is provided by several arterials which serve the Tukwila retail, office and industrial centers. Immediate site access is provided by the east -west arterial - Tukwila Parkway and the north -south arterial - Andover Park East. Tukwila Parkway transitions between a four lane and five lane street to accommodate through and intersection traffic between the "T- Line" Bridge and Southcenter Parkway. Tukwila Parkway provides access to I -5 and 1- 405 ramps. The "T- Line" Bridge is located immediately east of the intersec- tions of Andover Park East and Tukwila Parkway. It connects Tukwila Parkway with Southcenter Blvd., located north of 1 -405, by providing access across 1 -405. Tukwila Parkway's connection to Christianson Road (north -south street located east of Andover Park East) was eliminated with the recent construction of the "T- Line" Bridge. 2 M;r/IN'cJ_ ti, O J ) FJU_TII,� • 75,40 u Crow:: fir_ x.'10 5t. S, +c sr rmL u_ -,,,.c ( Ij 9 (OYHIL SIDLAL 0 - J FIG. 1 PRELIMINARY SITE PLAN Andover Park East is a four lane arterial between Tukwila Parkway and Strander Blvd. (east -west arterial approximately 2000 feet south of Tukwila Parkway). Andover Park East transitions to five lanes at Strander Blvd. to provide a left turn lane at the intersection. Strander Blvd. also provides left turn lanes in a five lane section. Strander Blvd. provides access across the Green River and connects to the West Valley Highway which links Tukwila with development north and south and includes ramp connections to I -405. Andover Park East extends south to S. 180th St. which provides east -west access from west of I -5 across the valley and Petrovisky Road. Andover Park West is a major north -south arterial located approxi- mately 1,200 feet west of Andover Park East at the eastern boundary of the Southcenter Shopping Mall. Baker Blvd. is a four lane arterial located approximately 1,200 feet south of Tukwila Parkway. Baker Blvd. provides east -west access between Southcenter and the office development located west of the Green River. Immediately south of the Ebasco site, Evans /Black Drive provides two lane access between the railroad right -of -way on the property's west boundary and Andover Park East. Traffic Control Existing traffic signals are located at the following nearby intersections: • Strander Blvd. @ Andover Park East • Strander Blvd. @ Andover Park West The remaining intersections are controlled by stop signs. Tukwila Parkway traffic has the right -of -way between Southcenter Parkway and Southcenter Blvd. Andover Park East traffic is controlled by the signal at Strander Blvd. and a stop sign at Tukwila Parkway. Baker Blvd. and Evans Black Drive traffic is controlled by stop signs at Andover Park East. Ebasco Site Access Existing Ebasco driveways are located along Andover Park East, 340. feet south of Tukwila Parkway and off of Evans /Black Drive, 725 feet south of Tukwila Parkway. Ebasco driveways on Tukwila Parkway are located approximately 200 feet and 500 feet west of Andover Park East. Driveways located on the east side of Andover Park East provide access to an auto service station, two small office buildings and, opposite of Evans /Black Drive, a waterbed retail outlet business. The driveways on Andover Park East are located as follows: 4 Driveway Distance South of Tukwila Pkwy Westside Eastside 1. Service Station 125' 2. Service Station and Office Building #1 215' 3. Ebasco 340' 4. Office Building #1 390' 5. Office Building #2 450' 6. Office Building #2 625' 7. Waterbed Outlet 665' 8. Evans /Black Drive 725' 9. Waterbed Outlet 780' Existing Traffic Traffic count information for this traffic analysis was obtained from City of Tukwila file data. In addition AM and PM peak hour manual turning movement counts were made during March 1, 1990 and March 6, 1990 at the following intersections: Location Date 1. Andover Park East & Baker Blvd. 3/1 PM, 3/2 AM 2. Andover Park East & Tukwila Pkwy. 3/1 PM, 3/2 AM 3. Andover Park East & Strander Blvd. 3/5 PM, 3/6 AM 4. Andover Park West & Tukwila Pkwy. 3/5 PM, 3/6 AM The highest peak period was determined to be the PM peak. The Manual Pm peak hour counts were made for the time period of 3:00 pm through 6:00 pm. These counts indicated the peak hour period began during the 3:15/3:30 time interval. This count data was compared with 1989 City Count data. Based on this review it was determined this count information was consistent with the peak traffic flow for southbound Andover Park East (APE) traffic, but northbound APE traffic peaked during the 12:00 - 1:00 pm period. Similarly, westbound Tukwila Parkway traffic peaked during the later afternoon time period and eastbound traffic peaked during the 12:00 am - 1:00 pm lunch hour period. As a consequence, the manual PM peak count data was increased by 3% to reflect noon hour traffic. This rate was calculated by comparing the net difference in approach traffic for the two time periods at the intersections of Andover Park East and Strander Blvd. and Andover Park West and Tukwila Parkway. It should also be noted that in reviewing the previous count records, it appears there has been a recent shift in travel patterns that are probably the result of construction on I -405 and the completion of the "T- Line" Bridge. 5 The following provides . a summary of existing traffic count data in the vicinity of the Ebasco Site: Description Directional PM Peak Hour (12:00 - 1:00) Directional Average Weekday 1. Andover Park East - South of Tukwila Parkway 265 SB 505 NB 4,450 SB 4,580 NB 2. Tukwila Parkway - East of Andover Park East 610 SB 355 EB 6,780 WB 4,350 EB PROPOSED PROJECT AND EVALUATION The proposed modification and addition to the existing Ebasco Building will increase the building's size by 14,000 square feet. The building expansion would occur on the south side of the building which is closest to Evans /Black Drive. The only change in existing driveways serving the site would be to shift the most western drive off of Evans /Black Drive to the east to better accommodate a truck loading dock that would be located on the southwest corner of the expanded building. Street System For the purpose of this analysis, the street system was assumed to remain as -is in order to compare "before and after" traffic impacts. Traffic Control Traffic control improvements were analyzed in response to evaluat- ing methods for improving degree of service based on existing traffic and additional traffic generated by the proposed building improvements. Traffic Generated Additional traffic generated on the street system was determined by comparing the amount of existing traffic generated by the site with the traffic that will occur based on the proposed modification and building addition. Trip generation rates have been based on generation rates prepared by the Institute of Transportation Engineers (ITE). The ITE Trip Generation Manual, 4th Edition, 1987, as formatted on Software by MICROTRANS was used for this analysis. Trip rates for the existing and proposed condition are included in the report Appendix. The results of the calculation are as follows: 6 As indicated average weekday traffic would increase by 3,047 trips. The AM peak would be reduced by 32 trips and the PM would increase by 269 trips. The additional PM trips are 179 entering trips and 90 exiting trips. Traffic Distribution The additional trips entering and exiting the site during the peak hour were added to the existing peak hour traffic flows by assigning entry and exit trips as follows: Location Exit Trips. Entry Trips 1. T -Line Bridge 20 45 2. Tukwila Parkway West of APW 20 30 3. Southcenter 10 15 4. Strander Blvd. West of APW 10 25 5. Andover Park W. South of Strander 10 +20 6.

The following summarizes the results of this analysis. Intersection 1. Southcenter Blvd. @ T -Line Bridge 2. Tukwila Parkway @ Andover Park East 3. Tukwila Parkway @ Andover Park West 4. Baker Blvd. @ Andover Park East 5. Strander Blvd. @ Andover Park East Existing Resultant LOS LOS LOS w/Mitigaticn D* D* E* E* A w /signal F* F* A w /signal D* D* A w /signal * LOS based on critical move (left- turn.NB to EB for #1, #2, #3; and side street lefts for #4). Based on this analysis the site generated traffic did not apprecia- bly lower existing LOS. However, existing left turning traffic is experiencing delays as indicated. A City signal warrant count for Andover Park East and Tukwila Parkway in August, 1989 indicated the intersection exceeds signal warrant #1 criteria. Increased Traffic The City of Tukwila is in the process of developing future year 2010 traffic forecasts for their arterial street system. Current project status indicates Tukwila Parkway east of Andover Park East would have an AWDT of 12,510 (7,570 westbound and 4,940 eastbound). Andover Park East would have a AWDT of 12,770 (6,430 southbound and 6,340 northbound) south of Tukwila Parkway. The proposed addition- al site generated traffic results in an increase of 1,015 trips to the existing 11,130 AWDT on Tukwila Parkway and 2,032 trips to the existing 9,030 on Andover Park East. These additional trips represent 73.5% of the future traffic increase on Tukwila Parkway and 54.3% on Andover Park East. 10 Driveway Analysis An analysis of the Ebasco driveway on Andover Park East was accomplished by completing capacity delay and queue calculations based on the trip rates developed from the ITE Trip Generation Manual. The PM peak hour trips were assigned proportionately to Tukwila Parkway, Evans /Black Dr., and the main Ebasco driveway on Andover Park East. These calculations are included in the Appendix. They are summarized as follows: Total Delay (exit right) = 5.01 sec. Total Delay (exit left) = 14.92 sec. Mean Delay (exit right) = 4.25 sec. Mean Delay (exit left) = 12.11 sec. Queue (exit right) = 0.178 vehicle delay Queue (exit left) = 0.233 vehicle delay Delay (exit left + entry left) = 16.7 sec. Capacity (LOS): Exit to Left = C Entry Left = A Exit to Right = A Based on these calculations, it does not appear the driveway usage will create significant traffic impacts on existing driveway use for business along the east side of Andover Park East. Mitigation The key Public Works Improvement associated with the proposed site modifications include amount of traffic increase, roadway widening; traffic signalization and construction of sidewalks. The City has proposed that future traffic improvements include (1) roadway widening from a width of 51 feet to a width of 57 feet to accommo- date five lanes of traffic (2) traffic signalization for Tukwila Parkway at Andover Park East, and Andover Park East at Baker Blvd, and (3) possibly widening the existing 6' sidewalk located on the Ebasco Site along Andover Park East to a width of 10 feet to meet criteria developed for the City's sidewalk plan. The widening of Andover Park East to a 57 foot section would provide for 5 -lanes with two lanes in each direction and a left turn lane. Figure 4 shows the configuration of channelization for this ultimate widening. Based on the existing 51 foot roadway width it would be necessary to widen three feet on each side of the street. 11 PRoPOSEo DEI/ELOPMEAir cirys p'r?1q .IMEE'r.s rio/V ANDO 6/T PARK .E:457- F/4OHE 4 The most impact the proposed development has on existing traffic is the 73.5% and 54.3% increase in "allowable" future trips on Tukwila Parkway and Andover Park East based on the year 2010 AWDT traffic forecasts. This increase results in a AWDT ,increase of 9.1% and 22.5% on the existing traffic, respectively. Review of intersec- tion capacity does not indicate generated traffic will create significant impacts. However, the existing intersection has sufficient traffic to warrant signalization. Sidewalks could be the primary issue which will determine timing or phasing of the roadway widening project. If the 10 foot sidewalk width is required now, the new curb line on the west side of Andover Park East should be shifted 3 feet to the west to accommo- date the proposed street widening. As a result, the new sidewalk would be constructed so as to alleviate future revisions. 13 APPENDIX EBASCO SITE TRAFFIC ANALYSIS -- EXISTING CONDITIONS SUMMARY SUMMARY OF AVERAGE VEHICLE TRIP GENERATION AVERAGE WEEKDAY DRIVEWAY VOLUMES 3/7/90 LAND USE SIZE '24 HOUR AM PK HOUR PM PK HOUR TWO-WAY VOLUME ENTER EXIT ENTER EXIT GENERAL OFFICE 24.5 TH.GR.SQ.FT. 478 52 8 1O 51 GENERAL OFFICE 30 TH.GR.SQ.FT. 556 62 9 12 61 CORPORATE H.Q.
