The purpose of this subchapter is to establish minimum post construction stormwater management requirements, and also to protect the health, safety, and general welfare of the public within this jurisdiction through the regulation of stormwater discharges to the municipal separate storm sewer system (MS4) as required by federal and state law. This subchapter establishes methods for controlling the introduction of pollutants into the MS4 in compliance with requirements of the National Pollutant Discharge Elimination System (NPDES) permit process. The objectives of this subchapter are:
   (A)   To regulate, and reduce, the contribution of pollutants to MS4 conveyances from post construction stormwater discharges;
   (B)   To reduce and/or minimize the total annual surface water runoff rate and volume entering into the MS4 conveyance system through post construction stormwater management controls;
   (C)   To require permanent post construction stormwater runoff controls be included as part of new development, and retrofit existing development where practicable to improve overall water quality within the MS4 conveyance system;
   (D)   To establish provisions for the long-term responsibility for and maintenance of structural and nonstructural stormwater Best Management Practices to ensure that they continue to function as designed, are maintained, and do not threaten public safety;
   (E)   To establish legal authority to carry out all inspection, surveillance and monitoring procedures as necessary to ensure compliance with this subchapter; and
   (F)   To facilitate compliance with state and federal standards and permits by owners of construction sites, developments and permanent Best Management Practices (BMPs) within the MS4 jurisdictional limits of the city.
