Closed depression definition
Closed depression means an area greater than five thousand square feet at overflow elevation that is low-lying and that has no or such a limited surface water outlet that the area acts as a stormwater retention facility.
Closed depression means a topographical basin where water ponds to a seasonal high water mark, has no external drainage, and drainage may occur either through direct conduits to groundwater or low areas where water ponds and infiltrates into the groundwater. Closed depressions may be identified using topographic maps and visual interpretation, ArcGIS tools, or other methods. A seasonal high water mark may include, but is not limited to, areas that collect and retain water for extended time
Closed depression means any low-lying area of iand, either natural or man-made, which receives stormwater;

Closed depression means an area greater than five thousand square feet at overflow elevation thatwhich is low-lying and that either has no, or such a limited, surface water outlet that during storm events the area acts as a stormwater retention facilitybasin, with more than 5,000 square feet at overflow elevation.
Closed depression means a low lying area, which has no, or such a limited, surface outlet that in most storm events acts as a retention basin, holding water for infiltration into the ground or evaporation into the air. By their nature, closed depressions may contain wetlands.
