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.

Purposes and Objectives
The regulations of this section are intended to protect and promote the public health, safety and welfare by preventing the introduction of potentially harmful materials into the city storm sewer system; to protect property from potential stormwater damage; to maintain and enhance water quality; and to meet the requirements in the City's National Pollutant Discharge Elimination System Permit for Stormwater Discharges. Other specific objectives of these regulations are to:
- provide for the enforcement of the city’s stormwater quality management program;
- reduce the discharge of pollutants to the storm sewer system to the maximum extent practicable by requiring, where appropriate, the use of best management practices, structural and/or nonstructural stormwater quantity and quality control measures and other provisions;
- provide for the inspection and proper maintenance of structural and nonstructural stormwater controls and the municipal separate storm sewer;
- prohibit non-stormwater discharges to the city storm sewer and require the removal of illicit connections to the city storm sewer;
- prevent improper disposal of materials that degrade water quality;
- permit sampling and monitoring for pollutants such as those associated with illicit discharges, improper disposal, industrial and construction activities, and the application of pesticides, herbicides, and fertilizers; and
- reduce erosion associated with stormwater runoff.
The regulations of this section apply govern the development and use of land and structures within the corporate limits of the city.

- New Development
- It is the duty of all property owners, in order to abate and prevent nuisances resulting from improper drainage, to provide at their own expense a proper and adequate drainage system of their respective premises, such drainage system to conform to the design established by the city.
- Rainwater leaders may not extend beyond the building or property line, but rather must be built in chases or on the inside of the wall, and may not empty on any street or sidewalk.
- No person may construct or install any ditch, pipe or other device for the diversion or transmission of storm drainage that will in any way affect the operation or maintenance of city street, water, sanitary sewer or storm sewer facilities without a permit issued by the Water Resources Director upon a finding that such city facilities will not be adversely affected by such construction or installation.
In accordance with city policy the developer is responsible for establishing proper connections with existing storm sewer lines and bears ultimate responsibility for the correction of any problems associated with that connection. (See Roadway and Utility Design Manual)
