CAG-20-399, Adden #2-23 Approved by Cheryl Beyer via 4/26/2023 email City of Renton 1 Burnett Ave S & Williams Ave S Water Quality Retrofit Scope of Services – Amendment 2 Exhibit A-2 SCOPE OF SERVICES – Amendment 2 City of Renton Burnett Ave S & Williams Ave S Water Quality Retrofit April 21, 2023 Statement of Understanding This scope of services presents additional scope under Amendment 2, including a 95% submittal package and Services During Construction, for the City of Renton (City) Burnett Ave S & Williams Ave S Water Quality Retrofit project (project). All other scope elements and assumptions from the original scope of services and Amendment 1 remain in place. The City has received funding from the Washington State Department of Ecology (Ecology) through a Stormwater Financial Assistance Program (SFAP) grant for this project, specifically for the retrofit design of water quality treatment devices. The City of Renton, in conjunction with the Ecology grant, plans to complete the design for retrofitting water quality treatment facilities to the urbanized Burnett Ave South and Williams Ave South drainage area and upgrade the existing storm water conveyance infrastructure. The project is located in downtown Renton, along Burnett Ave S and Williams Ave S, north of S 2nd Street, and south of the Cedar River. The project area is zoned for residential and light commercial properties. The project area has experienced flooding of an apartment building along Burnett Ave S. Hydrologic and hydraulic analysis of the project system, conducted in 2018 as part of the City’s Downtown Utility Improvements Project, indicated insufficient stormwater conveyance capacity and surface flooding within the project area. This analysis also indicated that the existing stormwater outfall to the Cedar River is undersized. There are currently no water quality treatment facilities along the project corridor. Due to undersized stormwater pipes and capacity limitations, the existing stormwater system is inadequate and does not meet the City’s current surface water design standards. The scope identifies the engineering services to be performed by BHC Consultants, LLC (BHC) and the following subconsultants: Transportation Engineering NorthWest (TENW), traffic control plans and right-of-way improvements. Scope of Services BHC proposes the following task elements for this Scope of Services: Task 100 – Project Management This task includes coordination and management of engineering work from project initiation through completion of design and services during construction. Subtasks include the following: 100.1Data Review and Project Development No additional scope under Amendment 2. 100.2Correspondence and Coordination with City Maintain regular telephone, email, and other communications with the City Project Manager and operations staff, as necessary to execute the work.
