Replacing the Quantico Creek Culvert
Project type: Resilience
Project status: In progress
Funding awarded: $330,750
Construction work began in September 2016 to replace an undersized culvert on Quantico Creek.
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.
