![]() Construction is anticipated to begin in late 2023 and take 9-12 months to complete. In the months ahead the project team will continue to refine the design, seek and incorporate input from the community, and obtain necessary environmental permits. The city was awarded $588,000 in Stormwater Local Assistance grant funding from the Virginia Department of Environmental Quality in 2021 to help pay for the $1.575M project. This project will be partially paid for by the city's stormwater utility fee. The aquatic benches create shallow water habitats for plants and animals.

The sediment forebays will be easier to dredge in the future and greatly extend the intervals between dredging of the main pond. Dredge Clay, Plastic, Poly or Concrete lined channels or ponds safely. adding aquatic benching and plantings around the perimeter of the pond.adding two sediment forebays that will trap sediment before it enters the main pond area.repairing erosion at the two channels that flow into the pond and making them more resistant to erosion.This work will increase the pond’s pollutant removal capabilities, make future maintenance easier and more economic, improve aesthetics, and provide the community with credits to help meet the city’s Chesapeake Bay pollutant reduction targets. In addition to dredging the pond, the department plans to retrofit the pond to meet current specifications. The pond was last dredged in 2011 however, due to budgetary constraints, only a portion of the silt that had accumulated up to that point was removed. This restores the pond’s capacity to hold water capacity and its ability to continue to capture pollutants. Preventing pollutants from reaching Daniels Run improves the water quality in the Accotink Creek Watershed.ĭredging the pond is necessary about every 10 years to remove the silt that the pond captures over time. The stormwater management pond receives runoff from about 135 acres, and much of the sediment is captured in the pond. When it rains, stormwater runoff carrying sediment and debris flows downhill to Ashby Pond. Satoshi Eto, public works program manager, explains the project to dredge and improve Ashby Pond. The deeper pools will enhance water quality for local wildlife and improve the park’s aesthetics for visitors. Removing accumulated silt from the pond will increase the pond’s capacity to slow stormwater runoff and capture pollutants. ![]() The City of Fairfax Department of Public Works is developing plans to dredge and upgrade Ashby Pond.
