(A) The drainage system shall be designed to minimize adverse water quality impacts downstream and on the property itself. Detention basins shall incorporate design features to capture stormwater runoff pollutants. In particular, designers shall give preference to wet bottom and wetland designs in locations adjacent or near existing wetlands or in other areas where they are suitable and acceptable to the village and all flows from the development shall be routed through the basin (i.e., low flows shall not be bypassed). Dry basins with low flow bypasses may be preferred in certain developments to enhance multiple uses where suitable and acceptable to the village. Retention and infiltration of stormwater shall be promoted throughout the property's drainage system to reduce the volume of stormwater runoff and to reduce the quantity of runoff pollutants.
(B) The drainage system should incorporate multiple uses where practicable. Uses considered compatible with stormwater management include open space, aesthetics, aquatic habitat, recreation (boating, trails, playing fields), wetlands and water quality mitigation. The applicant should avoid using portions of the property exclusively for stormwater management.
