Are fences allowed in storm drainage easements?

Yes, as long as the fence does not interfere with the flow of drainage, redirect drainage to a neighboring property or damage underground pipes. In addition, permanent structures such as footings, brick piers or columns are not allowed in storm drainage easements. For further information about fences in easements, contact the Maintenance & Stormwater Management Division at 703-877-2800, TTY 711. For information about zoning requirements for fences, contact call the Zoning Permit Review Branch at 703-222-1082, TTY.


Are fences allowed in resource protection areas?

Fences are permitted in a Resource Protection Area (RPA) without an exception or waiver subject to compliance with certain design requirements that collectively maintain the functional value of the buffer. Fences should be designed so that they do not inhibit or alter surface flow (i.e., water must be able to flow under and through the fence unimpeded), and vegetation may only be removed to provide for the actual placement of the fence. Where vegetation is removed, it must be replaced with other native vegetation that is equally effective in retarding runoff, preventing erosion and filtering nonpoint source pollution from runoff. Fences should be located to avoid the removal of trees. If the fence were to be placed in an area that was an existing maintained lawn, the revegetation requirement would not be applicable. For further information, please contact Land Development Services at 703-324-1720, TTY 711.
