Combined Sewer and Stormwater Coordination (HDR) 6.1 — Combined Sewer and Stormwater Outfall Improvements HDR Engineering will provide the hydraulic design criteria, pressure rating, and recommended pipe size for the combined sewer outfall and stormwater outfall pipe crossings of the proposed Grand Avenue Park Bridge. These concepts will be based on future wet weather improvements that the City of Everett may implement. The combined sewer and stormwater outfalls will connect to the new piping provided as part of the City's Sewer M project along Grand Avenue. The combined sewer outfall will connect to the existing PSO1 and PSO2 outfall pipes along West Marine View Drive. The stormwater outfall will replace the existing PSO3 outfall pipe. In the subsequent design work KPFF will provide the design of the combined sewer outfall from the intersection of 16th Street and Grande Avenue across the bridge and to within approximately 10 feet of a new CSO regulator structure on Port of Everett property that will split flow to PSO1 and PSO2. KPFF will also provide the design of the stormwater outfall from 16th Street and Grand Avenue to PSO3. HDR will lead the design of the new CSO regulator structure and piping connections to PSO1 and PSO2. Work in this task will include: • Meet with KPFF, the City, and the City's consultant for the Sewer M Project and review the connection points and details for the routing of the combined sewer and stormwater flows. • Review the current City InfoSWMM model of the Sewer M Project and confirm the final pipe sizing for the bridge crossings. • Develop concepts for conveying and regulating flow to P501, PSO2 and the potential Port KPFF Consulting Engineer November 10, 2014 Grand Avenue Park Utility Bridge, Phase 1A Page 23 of 55
