Project No. 95-RS01, Contract No. 02-036 ISSUE Supplemental Agreement No. 1 to KPG's original scope of work for services. BACKGROUND In April 2002, KPG, Inc., began working on the design for the South 144th Street (TIB to Military Road) project and the half-street frontage improvements adjacent to the Cascade View Community Park. Additionally, a design report for South 144th Street between 'l.'lg and 42"a Avenue South was also to be developed to accommodate the future Tukwila Village development. The draf~ design report is completed and the half-street frontage improvements for the Cascade View Community Park have been constructed. Final design is nearing completion, except for the work associated with undergrounding power supply and subsequent coordination with Seattle City Light. Original contract amount was $184,081.42, including both the S 144~' Street project and the work associated with the Cascade View Community Park. ANALYSIS As thc design process progressed, several factors came forward which have necessitated revising thc original scope of work with KPG, Inc. First off, thc City originally planned on contracting with Seattle City Light for much of the design of thc underground conversion. Since that time, a decision has been made to have consultants provide that work for expediency and KPG, Inc., has subcontracted with Casne Engineering, Inc., for those services. Cost: not to exceed $87,295.30 Second, additional study was required for the design and design report. Specific issues needed were an in-depth analysis of access alternatives for the True Value parking lot on South 144th Street at 37z Avenue South and a signal warrant analysis for the intersection of South 144z Street at 42"d Avenue South. Cost: not to exceed $10,859.52 Total supplemental agreement cost not to exceed $98,154.82.

Mayor Senior Engineer Attested: Jane E. Cantu, City Clerk Exhibit A City of Tukwila South 144th Street Roadway Improvements 42"d Avenue South to Military Road KPG, Inc Supplemental Agreement No. 1 December 4, 2003 INTRODUCTION This Amendment is to provide design services to the City of Tukwila for a revised work scope for the South 144th Street Roadway Improvement Project. The original scope stated that Seattle City Light would provide the design for underground conversion of existing overhead utilities. The City of Tukwila decided to hire a consultant to complete the design so that the City has more control over the contents and completeness of the design documents. This amendment includes completing design drawings, specifications, and cost estimates for the underground conversion and coordinating the design with the City of Tukwila, Seattle City Light, telephone and CATV companies. The City is considering adding a traffic signal at the South 144~ Street and 42nd Avenue South traffic signal. This amendment includes performing a traffic signal warrant analysis to determine the suitability of a traffic signal. However, satisfying one of the warrants does not necessarily require the installation of a traffic signal and installation of a traffic signal does not require meeting any of the warrants. The City is considering changing the access to the True Value parking lot to accommodate the relocation of a Metro bus stop and to improve safety by increasing the separation between 37th Avenue South and the True Value driveway on South 144th Street. This work was not included in the original project scope of work. This Amendment No. 1 includes the following major changes in project scope: c3 Desigh of underground conversion of existing overhead'utilities. n Traffic Signal Warrant Analysis for the South 144~' Street and 42nd Avenue South intersection. ~ Evaluation of access alternatives to the True Value parking lot at South 144~ Street.

Page 5 of 5 hour and Fee estimate Hour and Fee Estimate Transportation Committee March 22, 2004 Present: Joan Hernandez, Chair; Pam Carter, Joe Duffle Jim Morrow, Frank Iriarte, Bob Giberson, Cyndy Knighton, Gall Labanara, Lucy Lauterbach; Sandra Meyer, Gregg Zimmerman- Renton; Rich Perteet-consultant; Sue Byers-KPG 1. Strander Boulevard Extension Gregg Zimmerman, Public Works Director in Renton, presented Renton's case for Tukwila supporting the Strander Boulevard Extension project. He said the project would benefit both cities, being the third east-west corridor in both cities besides S. 180th and Grady Way. The Strander project would provide access t° the Sounder rail station, reduce congestion on S. 180th and Grady, and would benefit freight. The project cost is somewhere between $47-52 million. Gregg said the project would compliment Tukwila's TOD. The Strander project ($2.3 m) has been combined with Tukwila's Klickitat project ($3.2 m) in an application to PSRC for design funds. Renton's design team for the project wants Tukwila to finalize its Sounder station design so they can plan the read near it. Gregg brought up a 1986 Interlocal Agreement which stipulates that Tukwila will pay half the local share costs of 80% federal funding grants received to pay for the Strander extension. The same Agreement says both will also pay half for federal grants received for S. 180th's improvement. Another handout showed the funding source for $47 m. That sheet showed Tukwila's share being $3.84 million and Renton's contribution being $2.49 m. Several other grants and donations are planned, and some have already been received. Gregg said Renton would pay half the cost of improvements in Tukwila, which comprise half the project costs. The road would go under the railroad, and would benefit from combining or moving closer together the Union Pacific and Burlington Northern tracks there. No bike path is planned, as a 12' sidewalk should provide adequate access for all. 30% design will be done in early 2005. Information. 2. Southcenter Parkway Extension Southcenter Parkway extends south of S. 180th to the south City limits. At the Committee's last meeting staff reported they had selected David Evans & Associates to do the P.S. & E. Since then a price of $350,577 has been negotiated. The budget was $381,000. The road will support the Segale annexation plans to extend the read further south. Part of the project will be to evaluate alignments for the roadway, so project management was a focus of the evaluation for who was selected. J(~an and Pam C had comments on the Scope of Services and Geotechnical Report requirements. Recommend proiect to COW and Reqular meetinqs for approval. ,_3. S. 144th Street prOject This project will run from TIB to Military Road, though some work will also be done TIB-42ha. KPG has been retained to engineer the project. Ms. Byers has worked on the bus stop at the True Value, and it has now been moved to Cascade View Park. It is near a'crosswalk to get to Larry's at 37th. The plan is to increase visibility to improve sight distance. Landscape trees and a small median strip will be put in west of 37th to act as traffic calmin~ objects. The TIB themes will be used on the portion of the street between TIB and 37"', with pede,strian lighting, similar bus shelters, and wide sidewalks. The sidewalks will narrow to 6 west of 37th, and cobra lights will replace ped lights. The City will need to get land donations for sidewalks. This supplement to the engineering contract is to pay for the work needed to move the bus stop from True Value, and for using KPG to negotiate with City Light about undergrounding. The $98,152.82 cost is within budget. As this is a Supplement to an existing contract no formal action is needed. Recommend issue to COW for information. 4. Tukwila International Boulevard (TIB) 138th~152nd Perteet has worked on engineering for TIB since 1999. In that time period there have been two Supplemental Agreements, one each for more time and more work. Jim said WSDOT caused much of the work done in 2002 and 2003 which comprise this $122,319.35 Supplemental Agreement #3. WSDOT has changed channelization five times. Funding will come from the 104/02 Commercial street fund. Again, as this is a Supplement, no formal action is necessary. Recommend issue of Supplement #3 with Perteet EnRineerinq to COW for information. Committee chair approval
