Replacing the Quantico Creek Culvert
Project type: Resilience
Funding awarded: $330,750
The project will replace an undersized and poorly aligned box culvert with an adequately sized one and restore and realign the stream channel at Rte. 633, on a tributary to Quantico Creek (Dewey's Creek) in Prince William County, Virginia.
- Reduce potential for structural failure of the Quantico Creek box culvert
- 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
- City 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; the replacement culvert will prevent future overtopping during storms and allow normal sediment flow. 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.
