The sanitary and storm sewer installation for Phase 4A of the West Hill Area Sanitary and Storm Sewer Separation project has been completed on West 7th Street from Iowa Avenue to Locust Street. There is still some sanitary sewer installation work that needs to be done in the 700 block of Locust. The remaining sewer work on Locust will not begin until the intersections that are now closed on West 7th are reopened. As of this update, the intersections at Chestnut, Pine, and Linn are scheduled to be reopened by the end of the work day on Friday, Oct. 26. Locust Street is still open between 7th and 8th. Advance notice of the closure of Locust will be provided when it becomes known.

The paving is substantially complete from Iowa to Spruce but 7th Street will remain closed until the sidewalks and driveways are completed and the dirt work and seeding behind the curb is done. That is also anticipated to be completed by Oct. 26 depending on the weather and any currently unknown issues that may arise.

Phase 4A of the West Hill Sewer Separation Project is tentatively scheduled to be completed by November 9. The original contract date was November 30.


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.

The report “shall include a schedule and estimated cost for completing each project identified therein, and an update on the city’s plans for financing the projects”. Further, “By DECEMBER 31, 2024, completed all projects described . . . above”.
