Stormwater Management Resolution

The City of Henderson is divided into two river basins, the Tar-Pamlico River and the Roanoke River basins.   In an effort to improve the water quality in both basins, the City of Henderson has implemented certain design requirements for new development and redevelopment sites to address both water quality and quantity for post-development stormwater runoff.

The City’s stormwater standards were adopted as a result of the Tar-Pamlico Nutrient Sensitive Waters and Phase II Community Rules.  Even though the City resides in both basins, the current stormwater ordinance applies to both basins within the City limits.  The overall water quantity standards for the City shall meet the current Tar-Pamlico Nutrient Sensitive Water and Phase II Community rules, which requires the maintenance to the predevelopment runoff rates for the 1-year, 24 hour storm.  The quantity controls will be achieved through the use of Best Management Practices (BMPs), such as wet ponds, engineered swales, constructed wetlands, bioretention cells, etc.

The City of Henderson requires the use and shall meet the standards set by the NCDENR Stormwater BMP Design Manual, latest revision.  This manual outlines the design requirements and guidance on the development of BMPs.
