[ARCHIVED] Loudoun Awarded Matching Grants for Water Quality Improvements

Link to information about the Loudoun County Stormwater Management Program

Loudoun County has been awarded more than $4 million in state funding for stream restorations and local water quality improvements. 

The Virginia Department of Environmental Quality has approved matching grants for four Loudoun projects from the Stormwater Local Assistance Fund (SLAF). Through a competitive application process, the SLAF provides 50/50 matching grants to local governments for the design and implementation of stormwater best management practices that reduce water quality pollutant loads in local waterways and the Chesapeake Bay.

The projects and grant amounts are:

  • Ashburn Lake Pond Enhancement, $2,130,446: The project will create a forebay, or reservoir, in Lake Ashburn, which will increase the lake’s ability to treat pollutants and enhance water quality to local waterways and the Chesapeake Bay.
  • Conklin Park Stream Restoration, $1,408,185: This project is located within Conklin Park in the Bull Run watershed and will restore an unnamed tributary to Elk Creek. The reduction of phosphorus, nitrogen and sediment in the stream will enhance water quality in the Potomac River and Chesapeake Bay.
  • Rostormel Court Outfall Restoration, $319,147: This project will repair and restore a highly eroded outfall channel, or discharge point, located within a stormwater easement in the Timberbrooke Community. This project will enhance water quality in Beaverdam Run, Broad Run, the Potomac River and the Chesapeake Bay by reducing the amount of phosphorus, nitrogen, and sediment from entering these waterways.
  • Nutrient Credit Purchase, $148,500: As part of the county’s efforts to limit the amount of pollutants that can enter the Chesapeake Bay, (Chesapeake Bay Total Maximum Daily Load Action Plan), the county purchased 30 pounds, or credits, of phosphorus in Fiscal Year 2022. The grant will allow the county to be reimbursed for 50 percent of the purchase of those credits.

Construction on the projects is expected to begin in late 2023 or early 2024. 

The Loudoun County Stormwater Management Program, which is administered by the Department of General Services, addresses the design, development, improvement, operation, inspection, maintenance and oversight of the county’s stormwater management system. More information is online at
