Post-Construction Storm Water Ordinances

To comply with federal and state law, Mecklenburg County and the Towns of Cornelius, Davidson, Huntersville, Matthews, Mint Hill and Pineville each adopted a Post-Construction Storm Water Ordinance effective June 30, 2007. These Ordinances apply to the zoning jurisdictions for the six Towns and to the two square mile area south of Pineville currently under Mecklenburg County's zoning jurisdiction.

The County and Towns' Ordinances are designed to offset some potential negative impacts to surface water that can result from development and redevelopment of land. Overall goals of the Post-Construction Ordinances include:

Compliance with state and federal regulations
Minimizing pollution in streams and lakes
Reducing stream bank erosion and flood risks
Preserving undisturbed stream buffers and open space
Protecting endangered aquatic species
Reducing long-term costs for watershed restoration
