City of Greensboro / County of Guilford

To address the adverse effects of urbanization on water quality, Federal, State and local regulations have been adopted to protect the quality of surface waters in the City of Greensboro. Chapter 27 of the City Code of Ordinances is the Stormwater Management Ordinance. The main objective of this ordinance is to provide enforcement authority to meet the City’s municipal NPDES Permit and associated Stormwater Management Plan.

On-site stormwater system maintenance entails property owners or management companies regularly maintaining the stormwater system on their property. Often, it is very effective for individual facilities to periodically clean out on-site stormwater structures to assist in the City’s effort in maintaining the stormwater system.

By regularly maintaining on-site storm sewer systems and open channel conveyances, a facility may reduce the amount of sediment and other pollutants that can potentially migrate into the City’s storm sewer system and downstream receiving waters. This helps the City meet the pollutant reduction goals associated with its Federal National Pollutant Discharge Elimination System (NPDES) Stormwater Permit. Also, periodic cleanings of the stormwater infrastructure can prevent water back ups in the system and potential damage from flooding due to a clogged system.
