Dry detention basins shall be designed to remove stormwater pollutants, to be safe, and as much as feasible, to be available for multiple uses.
(A) Drainage basins shall be designed so that eighty percent (80%) of their bottom area shall have standing water no longer than 72 hours after any runoff event equal to or less than the 100-year event, and after any tailwater affecting the discharge from the pond recedes. Underdrains directed to the pond outlet shall be used if necessary to accomplish this requirement.
(B) All dry detention basins shall be designed to remove stormwater pollutants.
