The National Pollutant Discharge Elimination System (NPDES) Phase II Stormwater Program is an effort to preserve, protect and improve the nation’s water resources from polluted stormwater runoff. The program requires the City of Lexington and other municipalities to obtain a Federal Stormwater Permit. The City of Lexington's permit was issued November 11, 2016.
A requirement of the Lexington permit was the adoption of post-construction stormwater regulations with the intent of managing stormwater runoff resulting from new development. The post-construction provisions are included in the stormwater control regulations located in Section 3.11 of Lexington's Unified Development Ordinance. The stormwater control regulations follow the N.C. Division of Energy, Mineral, and Land Natural Resources Stormwater Model Ordinance and the Best Management Practices (BMP) / Stormwater Control Measures (SCM) Design Manual, and were adopted by the Lexington City Council on November 13, 2017. The new regulations became effective November 13, 2017, and apply to all new development and redevelopment of one acre or more.
