1. The City, at its cost, will inspect and maintain the stormwater management facilities delineated and labeled on Exhibit A as follows: • Ponds 1 00, 200, 300, 400, 500, 600 and 700 The City will: a. Obtain certified as -built contours for all ponds and inspect the ponds, and associated outlet structures, culverts and outfall structures one year and two years after the completion of as-builts, including measuring sediment accumulation by a method accurate to within one vertical foot. Thereafter, the City will perform inspections in the fifth year after pond completion and every five years thereafter. If inspections show that sediment may accumulate to 50 percent of wet storage volume, or 25 percent of dry detention volume, within less than five years, the City will inspect more frequently. Pond function will be considered inadequate if sediment accumulation has decreased the wet storage volume by 50 percent or dry detention volume by 25 percent, and the City will restore the basin to its original design elevations and dimensions and restore vegetation in disturbed areas within one year of the inspection date. b. Inspect stormwater infiltration and filtration basins, including rain gardens, annually, to preserve live storage capacity at or above the design volume. Remove vegetation, maintain healthy plant growth and remove excess sediment and debris to ensure that the facilities continue to perform per design. d. Inspect conveyances and other structures annually. Ensure preservation of designed hydraulic capacity. 2.
