(A) Statement of purpose. It is the purpose of this chapter to protect, maintain and enhance the public health, safety, environment and general welfare by establishing requirements and procedures to control the adverse effects of increased post-development stormwater runoff and nonpoint and point source pollution associated with new development and redevelopment as well as illicit discharges into municipal stormwater systems. Proper management of construction-related and post development stormwater 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) The chapter seeks to meet the requirements of the city's National Pollutant Discharge Elimination System (NPDES) Permit and its general purposes through;
(1) Establishing decision-making process for development that protects the integrity of watersheds and preserve the health of water resources;
(2) Requiring new development and redevelopment maintain the pre-development hydrologic response in their post-development state as nearly as practicable to reduce flooding, stream bank erosion, nonpoint 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 stormwater management standards and design criteria for the regulation and control of stormwater runoff quantity and quality;
(4) Establishing design and review criteria for the construction, function, and use of structural stormwater Best Management Practices (BMPs) to meet the minimum post-development stormwater management standards;
(5) Encouraging the use of better management and set design practices, such as the use of vegetated conveyances for stormwater and the preservation of green space, riparian buffers and other conservation areas to the maximum extent practicable;
(6) Establishing provisions for the long-term responsibility for and maintenance of structural and nonstructural stormwater BMPs to ensure that they continue to function as designed, are maintained appropriately, and pose no threat to public safety; and
(7) Establishing administrative procedures for the submission, review, approval and disapproval of stormwater management plans, for the inspection of approved projects, and to assure appropriate long term maintenance.
