The City of Des Moines is initiating a new Project which is included in the City’s Long Term Control Plan, developed to eliminate combined sewer overflows (CSO). The Lower Oak Park and Highland Park Sewer Separation Project is located along the Des Moines River, north of downtown. Currently, stormwater in this area is collected and conveyed by both separate storm sewer and combined sewer systems. The combined storm sewer and sanitary sewer flows are conveyed to the Birdland Pump Station on Saylor Drive, south of the marina.
The Project team has submitted 60% plans to the City for review of work in Phase 1, which is located to the north and west of the 6th and Boston intersection. Additional public input will be gathered regarding the Phase 1 work at an open house in November. Plans will be available for review and discussion of possible construction impacts. Construction of Phase 1 will start in the Spring of 2017.
Preliminary design has also begun on the remaining portions of the project area with Final Design anticipated to be complete in the Spring of 2017. Construction is anticipated to start on the remaining portions of the project in the Summer of 2017 and be complete by the end of 2018.
