Stormwater Management Plan


The Stormwater Management Plan (PDF) will help the county to meet the following goals:

  • Ensure that the system performs to protect water quality by preventing the introduction of pollutants to the maximum extent practicable
  • Implement the program countywide providing equitable levels of service across the county
  • Include stormwater maintenance activities such as routine inspections; cleaning; and remedial and preventive repairs (maintained to original design standards)
  • Maintain the stormwater system to prevent quantity impact to citizens (e.g. localized flooding)
  • Integrate stormwater system performance with the Revised General Plan objectives
  • Mitigate stormwater impact on the ecology of natural stream channels to the maximum extent practicable

Loudoun County's plan addresses all six minimum control measures outlined in the general Virginia Stormwater Management Program (VSMP).

  • The primary purpose of this ordinance is to enable the county to comply with state requirements to reduce pollution from stormwater runoff into the rivers and streams of the commonwealth. 
  • The ordinance describes maintenance of the stormwater system, unlawful discharge to the stormwater system, violations, and enforcement.
