4A Road Closure Diagram 7-6-18

Phase 4A of the West Hill Area Sanitary and Storm Sewer Separation project is moving up 7th Street from Cedar toward Locust. The 100 and 200 blocks of East 7th have been paved but are not yet open to traffic. The areas behind the curb need to be backfilled and seeded, driveways and courtesy walks need to be replaced, and several other peripheral items are to be completed before it will be reopened. The intersection of Sycamore and 7th is now closed so it can be prepared for replacement and to be tied in to the new and existing paving in each direction. The intersection of Pine and 7th will be closed beginning on Monday, July 9, long enough to run new sewer pipe through it and install a new manhole. It will be reopened when that work is done.


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.

Background Information:

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.
