PROJECT UNDERSTANDING The City of Everett, Washington (City) is designing improvements to the City’s combined sewer system to reduce combined sewer overflow (CSO) discharges at NPDES permitted outfalls SRO7 and SRO8. The improvements are part of a plan to comply with the Department of Ecology (DOE) requirement of no more than one CSO event per year per outfall averaged over a moving 20-year period. Jacobs Engineering Group (Consultant) performed conceptual design and sizing of a CSO storage facility at 36th Street, combined sewer pipe upgrades on Pacific Avenue, and modified diversion controls to storage and overflow facilities associated with SRO7 and SRO8. During the design phase, the City requested additional out of scope work be preformed in support of the project. To date, with prior City approval, Jacobs has completed these tasks (listed in Section 3 below) utilizing the existing project budgets. To complete the Issue for Bid (IFB) packages for the 36th Street CSO Storage Tank and Pacific Avenue Pipeline Improvements, the Consultant is requesting the additional budget outlined in this scope. Additionally, the City has requested that Jacobs prepare and obtain a Shoring Permit from BNSF as part of design and to perform a Storm Sensitivity Analysis based on updated storm series information that developed by the City. This Amendment No. 2 includes budgets to complete IFB packages and complete the BNSF shoring permit and Storm Sensitivity Analysis, as well as project management and final geotechnical data collection and report preparation. 2.
