(A) The purpose of this chapter 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-development storm water runoff and non-point and point source pollution associated with new development and redevelopment as well as illicit discharges into municipal storm water systems. It has been determined that proper management of construction-related and post- development storm water runoff will minimize damage to public and private property and infrastructure, safeguard the public health, safety and general welfare, and protect water and aquatic resources.
(B) This chapter seeks to meet its general purpose through the following specific objectives and means:
(1) Establishing decision-making processes for development that protect the integrity of watersheds and preserve the health of water resources;
(2) Requiring that new development and redevelopment maintain the pre-development hydrologic response in the post-development state as nearly as practicable for the applicable design storm in order to reduce flooding, stream bank erosion, non-point and point source pollution and increases in stream temperature, and to maintain the integrity of stream channels and aquatic habitats;
(3) Establishing minimum post-development 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 best management practices (BMPs) that may be used to meet the minimum post-development storm water management standards;
(5) Encouraging the use of better management and site design practices, such as the use of vegetated conveyances for storm water and the preservation of greenspace and other conservation areas to the maximum extent practicable;
(6) Establishing provisions for the long-term responsibility for and maintenance of structural and non-structural storm water BMPs to ensure that they continue to function as designed, are maintained appropriately and pose no threat to public safety;
(7) Establishing administrative procedures for the submission, review, approval and disapproval of storm water management plans, for the inspection of approved projects and for the assurance of long-term maintenance;
(8) Controlling illicit discharges into the municipal separate storm water system; and
(9) Controlling erosion and sedimentation from construction activities.
