Dewey’s and Quantico Creeks Culvert Restoration Project
Project type: Resilience
Project status: Completed
Funding awarded: $330,750
Construction work began in September 2016 to improve resiliency of a culvert on Dewey’s Creek, a tributary of Quantico Creek.
The project will restore 400 feet of stream above the Possum Point Road culvert – located on Route 633 at the Prince William County and Town of Dumfries line – over Dewey’s Creek, a tributary of Quantico Creek in Prince William County, Virginia. Restoration will improve sediment transport, water flow and fish habitat and reduce the risk of flooding to the nearby community.
- Reduce potential for structural failure of the culvert over Dewey’s Creek.
- Improve access to 6.25 miles of aquatic habitat for Service trust species including American eels.
- Eliminates public safety hazard
- Protects adjacent property and critical community infrastructure including a public water main and an access road to the Possum Point power station
- Restores access to upstream habitat for American eel
- Town of Dumfries
- Prince William County
- American Rivers
The culvert functionality was compromised during Hurricane Sandy and it became clogged with sediment. Previous structures at the site have had a history of overtopping during high flow events. Stream restoration will prevent future overtopping during storms and allow normal sediment flow to return. Improvements to the site, which also currently presents a partial blockage to fish passage for American eel and river herring, will prevent future flooding and expand natural access to upstream habitat to these fish.
