(a) Upon or following the effective date of this Article, the Director shall enact regulations providing for specific requirements and standards for stormwater management and drainage upon all new developments and redevelopment projects. These regulations shall be written to minimize the discharge and transport of pollutants to storm drain systems and prevent the deterioration of water quality. At a minimum, these regulations shall address:
(1) Prevention of any direct discharge of untreated stormwater, either on or off-site and employ management measures that keep and manage on site the first one inch of rainfall from a 24-hour storm preceded by 48 hours of no measurable precipitation.
(2) Prevention of increased post-development discharge rates.
(3) Removal of a designated amount, determined by the percentage of impervious parcel area, of annual total load of pollutants generated from development or redevelopment runoff prior to any off-site discharge.
(4) Description and implementation of best management practices, and the continuation of those BMPs for appropriate periods of time.
(5) Protection of ground water from instances of polluted runoff infiltration.
(6) Protection and preservation of the stormwater collection system, including, but not limited to, open natural drainage ways and riparian areas, which together function to attenuate runoff volumes, peak discharges and pollutant loading to the water environment.
