SCOPE OF WORK
MANAGEMENT RESERVE REQUEST #4
SUPPLEMENT 7
AGENCY: CITY OF RENTON
CONSULTANT: KPG, P.S.
CONTRACT: CAG-15-089
PROJECT: RAINIER AVE S - S 3ra St to NW Yd PI
A. PROJECT DESCRIPTION
The City of Renton is planning to continue infrastructure improvements to the Rainier Ave S
corridor with a new Phase 4. The approximate project limits of the new phase are between 5 3rd
St and NW 3rd PI. Similar to Phase 3, this new phase includes infrastructure improvements for
enhanced transit mobility, traffic safety and pedestrian safety. Construction of Rainier Avenue S
- Phase 4 will be divided into two phases due to limited available construction funding. Phase 4A
(S 3rd St to S Tobin St) will be constructed first and followed by Phase 413 (S Tobin St to NW 3rd PI)
once funding becomes available. Design and right of way acquisition services will be performed
over the entire project length. The goals of Phase 4 are to enhance traffic flow, improve safety,
eliminate sub -standard conditions and provide an enhanced pedestrian environment.
B. PURPOSE
The City of Renton (AGENCY) is requesting that KPG, P.S. (CONSULTANT) provide supplemental
WSDOT Coordination and Stormwater Analysis Services for Rainier Ave 5 —S 3rd Street to NE 3rd
Place Project (PROJECT). Through the WSDOT Channelization Approval process, WSDOT Local
Programs informed the project team that all signalized intersection on State Routes requiring a
new or modified signal must have an Intersection Control Evaluation (ICE) completed.
Additionally, during the development of the Stormwater TIR, it was determined that Rainier
Avenue S may qualify for a flow control direct discharge exemption as outlined in the Renton
Surface Water Design Manual. If it is determined that the PROJECT does qualify for such an
exemption, the PROJECT will not have to consider certain stormwater BMP's as outlined in the
Surface Water Manual.
This supplemental agreement includes the following efforts
1. Prepare WSDOT Intersection Control Evaluation
Z. Perform and Document Hydrologic and Hydraulic Analysis to support the direct discharge
exemption
3. Update the Stormwater TIR with the Hydrologic/Hydraulic Analysis and findings
