(A) Performance standards. The proposed development, development activity, or redevelopment shall be planned and designed by a professional engineer who shall certify the system has been constructed and will be maintained to meet each of the following standards:
(1) Ensure that, after development or redevelopment, runoff from the site approximates the rate of flow, volume and timing of runoff that would have occurred following the same rainfall under existing conditions and to the extent practicable, the predevelopment conditions, unless runoff is discharged into an off-site drainage facility.
(2) Maintain the natural hydrodynamic characteristics of the watershed.
(3) Protect and, to the extent feasible, restore the quality of surface waters.
(4) Ensure that erosion during and after development and redevelopment is minimized.
(5) Protect the beneficial functioning of wetlands as areas for the natural storage of surface waters and the chemical reduction and assimilation of pollutants.
(6) Prevent increased flooding and damage that results from improper location, construction, and design of structures in areas which are presently subject to danger from flooding.
(7) Prevent or reverse salt water intrusion.
(8) Protect the natural fluctuating levels of salinity in estuarine areas.
(9) Protect, insofar as possible, the integrity of interdunal trough groundwater recharge areas.
(10) Minimize injury to flora and fauna and adverse impacts to fish and wildlife habitats.
(11) Otherwise further the objectives of this subchapter.
(B) Design standards. To ensure attainment of the objectives of this subchapter and to ensure that performance standards will be met, the design, construction and maintenance of drainage systems shall be consistent with best management practices of the engineer profession, the law and relevant codes of the United States, State of North Carolina, and the Town of Caswell Beach, to include but not limited to all town development codes, CAMA, and the adopted land use policy.
