Thereafter, the Permittee 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 Permittee 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 Permittee 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.
