Boat dock permits have limited applicability in Loudoun County. The county borders the Potomac River but has no significant public marina infrastructure. Private docks on the Potomac require permits from the Virginia Marine Resources Commission (VMRC) and Army Corps of Engineers. Most Ashburn residents have no waterfront access — HOA ponds prohibit docks and boats.
Loudoun County's Potomac River frontage in the northern part of the county is the only area where boat dock permits could apply. Private residential docks on the Potomac require a joint permit application through the Virginia Marine Resources Commission (VMRC) and U.S. Army Corps of Engineers under Section 10 of the Rivers and Harbors Act and Section 404 of the Clean Water Act. The VMRC permit process includes review of environmental impact, navigation clearance, and riparian rights. Loudoun County's zoning ordinance may impose additional setback and impervious surface requirements for structures in the Potomac River floodplain. For the vast majority of Ashburn and suburban Loudoun residents, boat docks are not relevant — HOA stormwater management ponds and detention basins are not navigable waterways and prohibit docks, boats, and swimming. Public boat access on the Potomac in Loudoun County is limited to a few put-in points. The county does not operate public marinas.
Unpermitted docks in the Potomac: VMRC and Corps of Engineers enforcement, potential removal order. HOA pond violations: HOA enforcement per CC&Rs. Floodplain construction without permit: county zoning violation.
