Resolution accepting the work of Compass Utility LLC as complete and authorizing release of the retainage after 30 days if no claims are filed in connection with the East Manawa Sewer Rehab, Phase VII. Project # PW19-09          

The area of East Manawa is very flat with open ditches.  There are no storm sewers in this area and the streets are thin asphalt or seal-coated rock roads.  During rainfall events, considerable surface ponding occurs due to the poor drainage.

Due to the narrow right-of-way (30 ft.) and the high water table in the area, conventional storm sewer construction is not practical.  The use of porous pavement in conjunction with a drainable granular base and shallow subdrain/conveyance system was determined to be the most cost effective means available to improve the area drainage.

The rehab program also includes installation of new sanitary sewers utilizing a vacuum system.

Phase I and II of the program have been completed and included Huron Circle from Navajo to north of Osage Street.  Phase III of the program was construction of the sanitary sewer vacuum pump station. Phase IV included the first phase of vacuum sewer installation with the porous pavement and subdrain system on Huron Circle from Navajo to just west of Blackhawk Street.  Phase V is complete and continued the rehab along Huron Circle from just west of Blackhawk Street to 585 feet east and Osage Street from Huron Circle to Victor Street. Phase VI is complete and included Blackhawk Street from Huron Circle to Victor Street and Victor Street from Osage to Blackhawk Street. 

Phase VII was located on Blackhawk Street from Victor to Huron Circle and Aztec Street from Huron Circle to Victor.

This project was included in the FY19 CIP with a budget of $1,000,000 in Sales Tax Funds.  The Division V costs were paid by Council Bluffs Water Works.

The Contractor completed the project on time and did not receive any non-compliance notices.

Approval of this resolution.
