CASE# I a REPORT FROM PUBLIC WORKS By: Public Works Staff Background: The Public Works Committee met on Tuesday, May 15, 2007 and discussed the following three cases: CITIZEN INPUT Case #1 Discuss Lined Pond Maintenance Responsibilities Background: 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 cannbt be constructed into the water table there is an increasing desire to achieve the aesthetic furiction of open surface water by installing an impermeable lining for ponds which would otherwise be dry as a result of percolation through the sandy soils. Lined ponds may lose thb integrity of their liner through improper installation or damage to the liner by activities from Jroperty owners or builders. A significant problem associated with the I repair of breached liners ~s the identification of the defect location. In addition, the repairs to the liner are usually costly. It is proposed that the City take an active role during the inspection of the pond liners during thbir installation. It would also be reasonable to require a surety sufficient to cover the repair of th~ liner during the period when most construction activity by builders is occurring. However following this period, it would be staffs recommendation that any repair be undertaken as a public !improvement project and special assessed to the benefiting property owner. Staffrecommend~ that staff be directed to prepare a policy relating to the installation of lined ponds within the City. I Consensus of the Co~ttee was to direct staff to develop a policy relating to the installation of lined ponds within the City based on the above discussion. Action: Ratify the recommendation of the Public Works Committee. -143-
