Phase 4A of the West Hill Area Sanitary and Storm Sewer Separation project (WHSSSSP) is moving up 7th Street from Iowa Avenue and is nearing Locust Street. All of the storm and sanitary sewer work has been completed from Iowa to Spruce on West 7th Street. The Pine and Chestnut intersections will be closed to be prepared for paving. Linn and Spruce intersections are now open after having the new storm sewer inlets and piping installed. We anticipate that 7th from Iowa to Linn will be paved within the next week or 10 days. That section of West 7th is currently being prepared for paving.

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.
