West Hill Sewer Separation Project Phase 4


072820 West Hill - No Parking SIgn on 8th Street (JPG)

The underground division of KE Flatwork, Inc., has completed work on Linn Street and from Linn Street to the Broadway intersection on 8th Street as part of the West Hill Sanitary and Storm Sewer Separation Project (WHSSSSP) Phase 4C. The contractor repaved Linn Street and is now preparing West 8th Street from Linn to just east of the Broadway intersection for paving which is expected to start in the next two weeks.

Work on this stage of Phase 4C is expected to continue to September 2, weather permitting. Once this section is reopened to traffic, the final stage of Phase 4C will begin. The final stage includes the Broadway and 8th Street intersection along with work on Roscoe Avenue and Maiden Lane. The current tentative schedule has all work completed by October 15, weather permitting.

A full closure of West 8th Street from Linn to Broadway, and Linn Street from 7th Street to 8th Street is in effect. Portions of West 8th Street from Iowa to Linn may have lane restrictions as the Phase 4B punch list items are completed.

Traffic is detoured to 7th Street from Cedar to Broadway, and Broadway from 7th Street back to 8th Street. No parking will be allowed on even number side (river side) of 7th Street from Cedar Street to Broadway, or on the east side (odd number) side of Broadway from 7th to 8th Street. The detour route will remain in place until the project is completed in October. There may be a slight change to the detour route once work begins on the final stage of Phase 4C.

All dates are tentative and dependent on weather conditions or other unforeseen circumstances. Drivers are urged to use caution when proceeding in or around construction areas and to find alternate routes of travel when possible.

Phase 4C began March 16, 2020. 


The West Hill Area Sanitary and Storm Sewer Project Phase 4C is scheduled to begin on March 16 with work on Iowa Avenue between 8th and 9th Streets and on 9th Street from Iowa to Chestnut. Phase 4C will be completed in three stages with the schedule for all work weather dependent. Phase 4C includes replacement of water main along with storm and sewer mains. The green area (map below) is the area that will be impacted by work in Phase 4C. 

A detour route has been established and will be implemented once work progresses to 8th Street. The detour is the same as the detour for Phase 4B (on 7th Street from Cedar to Broadway to provide the best path for traffic flow and return to West 8th Street at a traffic signal-controlled intersection). Heavy truck traffic will be re-routed away from the residential area. In order to provide a detour route through this neighborhood that is safer for traffic and parked vehicles, parking will again be limited to one side only on 7th Street. No Parking signs will be placed on the river side (even number side) to prohibit parking prior to the implementation of the detour later this summer.
