Resolution accepting the work of Compass Utility, LLC as complete and authorizing release of retainage after 30 days if no claims are filed in connection with the East Manawa Sewer Rehab, Phase VIII.  Project # PW20-09

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 the 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. Phases VI and VII are now complete and included Blackhawk Street, Victor Street from Osage to Blackhawk, and Aztec Street from Huron Circle to Victor.

Phase VIII is complete and included Victor Street from Navajo to Blackhawk and Aztec Street from Victor Street to the south.

The project was included in the FY20 CIP with a budget of $1,500,000 in GO Bond funding. The Division V costs were paid by the Council Bluffs Water Works.

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

Approval of this resolution.
