SvR provided civil engineering design services as a subconsultant on the Henderson/M.L.King CSO Project. Design included stormwater detention, erosion control, utility services and utility relocations, paving plans, 375 ft of sewer main, landscape and irrigation plans, and preparation of City of Seattle Private Contract Plans for right-of-way improvements. SvR coordinated with Sound Transit, City of Seattle, and the City of Tukwila and our work included pre-design and construction document preparation for three related construction contracts. For the Overflow Pipeline Contract predesign, SvR modeled and designed 1,000 LF of 66” diameter combined sewer overflow to the Duwamish River. For the Tunnel Contract and the Pump Station Contract SvR prepared the civil site work and landscape plans for the two tunnel portals and the pump station sites.
