Update: Scott's Run Nature Preserve is closed through July 4 for an urgent sewer project.

Beginning on Monday, Feb. 16, Scott’s Run Nature Preserve will be closed for an urgent sewer project to renew and rehabilitate the Scott's Run Siphon wastewater facility. Contractors for the Fairfax County Department of Public Works and Environmental Services will complete this work, which is expected to take approximately three months to complete, depending on weather conditions.

This infrastructure enables the transportation of wastewater across the Potomac River, through Carderock National Park and connects to D.C. Water’s Potomac Interceptor in Maryland. This project is essential to maintaining uninterrupted service and preventing potential wastewater overflow into the Potomac River.

To ensure public safety and protect natural resources, Scott’s Run Nature Preserve, including the east and west parking areas and all trails, will be closed for the duration of the emergency work. Residents are encouraged to use the Park Authority’s Park Amenity Locator and Trail Buddy to identify alternate parks and trails during this closure. The public will be notified when the park reopens.

Updates regarding project progress and any changes to the timeline will be available online at the Scott’s Run Siphon Rehabilitation project webpage.

For more information about the project, please email Sara Ferrance, Engineer V Fairfax County Wastewater Collection Division at sara.ferrance@fairfaxcounty.gov. Questions related to the park closure may be directed to the Park Information Office at parkmail@fairfaxcounty.gov.

Scott's Run Nature Preserve is located at 7400 Georgetown Pike in McLean. For more information, visit the Scott's Run Nature Preserve website or call 703-759-9018.
