West Hill Sewer Separation Project Phase 4
UPDATE MAY 6, 2020
Pavement restoration has begun in the first stage of Phase 4C of the West Hill Sanitary and Storm Sewer Separation Project (WHSSSSP) with 9th Street repaved from Chestnut to Iowa Avenue on May 4 and Iowa Avenue is to be repaved on May 7 from 9th to 8th streets. Sidewalk replacement will be completed May 11-15 with all work expected to wrap up in this stage by the Memorial Day weekend, weather permitting.
The second stage will begin on Monday, May 11, with 8th Street closed to traffic from Cedar to Broadway. The Phase 4B detour will be implemented on May 11. That detour will take vehicle traffic to 7th Street from Cedar to Broadway with parking on 7th Street restricted to one side of the street only. The closure will enable to the contractor to complete "punch list" items from Phase 4B from Cedar to Linn, and to begin pavement removal and underground work on Linn Street and from Linn to Broadway on 8th.
Phase 4C began March 16, 2020, with underground work on the first stage (Iowa Avenue from 8th to 9th Street and 9th Street from Iowa Avenue to Chestnut Street).
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.
The contract for Phase 4 of the West Hill Sewer Separation Project was awarded to KE Flatwork, Inc., Eldridge, Iowa, on April 5, 2018, in the amount of $6,109,522.45.
