The purpose of this subchapter is to protect, maintain and enhance the public health, safety, environment and general welfare by establishing minimum requirements and procedures to control the adverse effects of increased post-construction storm water runoff and non-point source pollution associated with new development and redevelopment. It has been determined that proper management of construction- related and post-construction storm water runoff will minimize damage to public and private property and infrastructure, safeguard the public health, safety, and general welfare, protect water and aquatic resources and establishes methods for controlling the introduction of pollutants into the municipal separate storm sewer system (MS4) in order to comply with requirements of the National Pollutant Discharge Elimination System (NPDES) permit process. The objectives of this subchapter are:
(1) Establishing decision-making processes for development that protects the integrity of watersheds and preserves the health of water resources;
(2) Minimizing changes to the pre-development hydrologic response for new development and redevelopment in their post- construction state in accordance with the requirements of this subchapter for the applicable design storm in order to reduce flooding, stream bank erosion, and non-point and point source pollution, as well as to maintain the integrity of stream channels, aquatic habitats and healthy stream temperatures;
(3) Establishing minimum post-construction storm water management standards and design criteria for the regulation and control of storm water runoff quantity and quality;
(4) Establishing design and review criteria for the construction, function. and use of structural storm water control facilities that may be used to meet the minimum post-construction storm water management standards;
(5) Establishing criteria for the use of better management and site design practices, such as the preservation of green space and other conservation areas;
(6) Establishing provisions for the long-term responsibility for and maintenance of structural and nonstructural storm water best management practices (BMPs) to ensure that they continue to function as designed, are maintained appropriately, and pose minimum risk to public safety; and
(7) Establishing administrative procedures for the submission, review, approval and disapproval of storm water management plans, for the inspection of approved projects, and to assure appropriate long-term maintenance.
