BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
The Department of Public Works (DPW) maintains the City's system of storm sewers. Storm sewers have a functional lifespan of approximately 75 years. As a storm sewer ages, the pipes develop cracks caused by material degradation, soil settlement, root intrusion, and/or adjacent construction. When a segment of storm sewer approaches the end of its useful life, the extent and severity of pipe degradation results in a high probability for pipe/system failure. Pipe failure may cause sinkholes in roadway surfaces and may also result in flooding of homes, businesses and/or public rights-of-way. The City has relined approximately 240,000 linear feet of pipe since the inception of the Storm Sewer Lining Program (SW017) in 2004, which has led to a reduction in localized flooding and related complaints.
In February 2022, the City Council awarded Bid 22-058, Storm Sewer Lining, to Hoerr Construction for the rehabilitation of storm sewer by the installation of cured-in-place pipe (CIPP). The contract includes a pre-inspection and cleaning of all pipes, the installation of CIPP, and the inspection of each completed installation by closed circuit television. The term of this contract was for seven months from date of award to October 15, 2022 with two, one-year options to extend.

During the initial year of the contract, Hoerr Construction completed the rehabilitation of approximately 11,100 feet of storm sewer ranging from 8 inches to 30 inches in diameter by installation of CIPP as well as the cleaning and televising of the storm sewer. In 2022, work was completed in Lakewood Crossing and Ivy Ridge subdivisions as well ...
