Phase 2 of the Cole Creek Sewer Separation project is nearing design completion. The meeting will focus on the alignment of the sewer separation and a general schedule. Please join us to learn more!
Phase 2 preliminary and final design will begin in September 2015. Design completion will occur in December 2016. Construction will occur in 2018 - 2019.
The specific project area for Cole Creek CSO 204 Phase 2 is bounded roughly by Spaulding Street on the north, 60th Street on the east, Maple Street on the south, and 63rd Street on the west.
The Phase 2 project includes a new sanitary sewer along 63rd Street from Spaulding Street to Bedford Avenue and on 61st Street from Bedford Avenue to 40 feet south of NW Radial Hwy which will enable separation of the main combined sewer in the area. This sewer will connect to the new sanitary sewer being built under Phase 1 construction (2015-2016).
Evans Street, Pinkney Street, Emmet Street, Spencer Street, and Bedford Avenue between 61st Street and 63rd Street will also have new sanitary sewer installed to tie into the new line along 63rd Street.
The Cole Creek Sewer Separation project is a multi-phase project located in a 522 acre basin referred to as Cole Creek CSO 204. Itis bordered on the north by Brown Street, on the east by 52nd Street, on the south by Northwest Radial Highway, and on the west by Cole Creek.
The Phase 2 preliminary design includes a new sanitary sewer along 63rd Street from Spaulding to Spencer Streets. This sewer will connect to the new sanitary sewer being built under Phase 1 construction (2015-2016). Evans Street, Pinkney Street, Emmet Street, and Bedford Street between 61st Street and 63rd Street will also have some new sanitary sewer installed that connects to the 63rd Street sanitary system.
Specifically, Phase 2 will include approximately 5,200 linear feet of 8-inch diameter sanitary sewer and 2,100 linear feet of 10-inch diameter sanitary sewer to increase capacity and separate the combined sewers on 63rd Street and east branching side streets. Storm sewer construction will primarily consist of re-routing inlets and addressing some street flooding issues by constructing approximately 2,300 linear feet of 15 to 21-inch storm sewer.
This project is Phase 2 of approximately six planned phases that will convert the existing combined sewers to either storm or sanitary sewer plus providing additional capacity with new sewers. It will ultimately result in reduced sewer backups into area homes and reductions in combined sewer overflow volume and flowrate to Cole Creek.
Specifically, Phase 2 construction is anticipated to include:
