UPDATE MAY 31, 2019

Work on Phase 4B of the West Hill Sewer Separation Project has steadily continued despite the wet weather with underground work set to begin next week on Iowa Avenue from the #7 Alley to the 8th Street intersection. Underground subcontractor KMA Excavating has completed work in the 200 block of East 8th Street and the 700 block of Sycamore with the 100 block of East 8th expected to be completed by the first of next week. Prime contractor KE Flatwork, Inc., has already started prepping these three blocks for paving and that is expected to begin around June 17.

The next portion of Phase 4B will involve Iowa Avenue and 8th Street up to the Chestnut Street intersection. Work should begin in the Iowa Avenue intersection with 8th Street early next week and progress south on Iowa Avenue toward the #7 Alley before moving up 8th toward Chestnut Street.

The contractor anticipates underground work to be completed on Iowa Avenue the first week of July with a temporary pavement put in place for the Fourth of July holiday. Paving of the intersection and sidewalks will be completed after the holiday.


The West Hill Area Sanitary and Storm Sewer Project Phase 4B began on March 21, 2019, in the 100 and 200 blocks of East 8th Street and the 700 block of Sycamore Street. Phase 4B includes replacement of water main along with storm and sewer mains. The red area (map above) is where Phase 4B will be through July 3, 2019. The pink areas are the rest of the areas where work will be done during 2019. Advance notice will be given before those streets are closed to traffic. 

A detour route has been established this week 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 is 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 is limited to one side only on 7th Street. No Parking signs were placed on the river side (even number side) to prohibit parking beginning Wednesday, March 20.

The project will be completed in two parts to ease the disruption of traffic on one of Muscatine’s busiest streets. Sewer replacement and replacement of the pavement will be completed from Cedar to Iowa during the first part that is expected to be completed by July 3. The second part from Iowa to Lynn is tentatively scheduled to begin on July 7 and anticipated to be completed by September 23. The entire project has an end date of October 4, 2019, weather permitting.
