Wetlands shall be protected from the adverse changes in runoff quality and quantity associated with land developments. In addition to the other requirements of this Code, the following mitigation criteria shall be met for all developments whose drainage flows into wetlands.
(A) The existing wetland shall be protected during the construction by appropriate soil erosion and sediment control measures.
(B) All storm water runoff from the development shall be routed through a preliminary detention/ sedimentation basin designed to capture the 2-year, 24-hour event and hold it for at least 24 hours before entering an existing detention pond. The basin shall be constructed before any site grading begins. In addition, the drainage hierarchy defined herein should be followed to minimize runoff volumes and rates being discharged to the wetland.
(C) A buffer strip at least 25 feet in width, preferably vegetated with native plant species, shall be maintained around the periphery of the wetland.
