A POLICY ON THE CONSTRUCTION AND MAINTENANCE OF LINED PONDS Introduction The utilization of storm water ponds has evolved into a basic element of subdivision design. Many of the storm water ponds constructed within the City are constructed below the water table making them normally wet ponds which provides an aesthetic benefit to the subdivision. For those ponds which cannot be constructed into the water table there is an increasing desire to achieve the aesthetic function of open surface water by installing and impermeable lining for ponds which would otherwise be dryas a result of percolation through the sandy soils. Lined ponds may lose the integrity of their liner through improper installation or damage to the liner by activities from property owners or builders. A significant problem associated with the repair of breached liners is the identification of the defect location. In addition, the repairs to the liner are usually costly. The City hereby establishes this policy to safeguard the taxpayers and protect new property owners from the cost of pond liner repaIr. Installation The City will take an active role during the installation of the pond liners by inspecting the liner for conformance with the approved plans and specifications. The installation in conformance to the plans and specifications shall be insured through an escrow or other surety acceptable to the finance director in the amount of 125% of the estimated cost of the pond liner. The surety shall be held through the installation period which shall be until certificates of occupancy are issued to all properties riparian to the lined pond. Maintenance Following the installation period, any repair necessary shall be undertaken as a public improvement project and special assessed to the riparian property owner following the procedure set forth in section 4.60 of City Code. Effective Date This policy shall become effective upon adoption by City Council. Adoption Date 14
