West Hill Sewer Separation Project Phase 4
UPDATE NOVEMBER 8, 2018
West 7th Street is now open from Iowa to the end of the 300 block including the cross streets of Pine and Chestnut. The intersections of Linn and Spruce on West 7th are still closed. The paving is substantially complete from Linn to Locust but it will remain closed until the sidewalks and driveways are completed, and the dirt work and seeding behind the curb are completed.
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 to Locust. The last block of sanitary sewer replacement for 2018 Phase 4A on Locust Street has begun and is expected to be completed by Monday (Nov. 12).
The need to accommodate the sewer work on Locust resulted in a decision to build a temporary connection of the #7 alley onto Spruce Street. Traffic can move out of the #7 alley in the 500 block to the east and out toward West 8th Street. Residents should note that access to Spruce from the #7 alley in the 400 block does not go through to Spruce. That alley tie-in was poured this week, is still curing, and is not open to traffic.
The arrows in the above map show the available alley access routes and escape routes back to West 8th Street.
Phase 4A of the West Hill Sewer Separation Project is tentatively scheduled to be completed in December.
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.
In 2004 Stanley Consultants Inc. signed a contract with the city to proceed with a study and projects for the West Hill area. On September 5, 2007, the city received a stamped Consent Order from the U.S. Environmental Protection Agency requiring that by December 31, 2010, the city would “submit to EPA and IDNR a report describing the projects needed to complete the separation of the remaining combined portions of the sewer system including the West Hill area”. 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”. Four projects have been identified, each estimated at $15 million to be implemented over the next 14 years to comply with the December 31, 2024 Consent Order date.

The sewer construction and street paving work for the West Hill Sewer Separation Project Phase 3C is complete.

The City and construction company crews have appreciated your patience during this construction year.
Contract for the West Hill Sewer Separation Project, Phase 3, was awarded to Hagerty Earthworks on April 16, 2015 in the amount of $4,988,668.
