Lower Potomac, located between the Potomac River shoreline and U.S. Route 1, is a residential and waterfront Fort Belvoir neighborhood with wooded edges and broad river views. The neighborhood’s character concentrates around the Fort Belvoir Marina area, where docks, a small ship’s store, and riverside picnic lawns set a practical, outdoors-forward tone. Streets read as low-slung, mid-century housing and newer townhome pockets, framed by tall trees and long setbacks. The pace centers on trails, boat slips, and open green space rather than a main commercial strip. Fort Belvoir Marina, the National Museum of the United States Army, and Gunston Hall act as local pillars for weekends and visiting guests. River Road and nearby parkland keep the geography front and center.
