Who Maintains the Storm Drainage System

The county maintains the public storm drainage system contained within dedicated storm drainage easements. The Virginia Department of Transportation maintains the storm systems in public street rights-of-way. Storm systems on land owned by other public bodies such as the Fairfax County Park Authority, Fairfax County Public Schools and the federal government are maintained by those entities. There are also numerous private systems that are the responsibility of private property owners, including driveway culverts and bridges that cross public drainage systems.

FEMA Special Flood Hazard Areas

Special Flood Hazard Areas are high risk areas that have a one-percent chance or more of being inundated by a base flood in any given year as identified by Federal Emergency Management Agency (FEMA). Floodplain management regulations must be enforced and mandatory purchase of flood insurance applies for these areas. For more information, please visit FEMA For Homeowners, Renters & Business Owners or Fairfax County Flood Information. See Fairfax County Special Flood Hazard Area Maps for watershed boundaries and RPA information.

Find your Watershed

Fairfax County has developed comprehensive watershed management plans for each of the county's 30 watersheds. A watershed management plan serves as a tool to identify and address the issues affecting our environment and to protect and restore the county's streams and other water resources.

You can open the map and click on a watershed name in the map to find completed plans, plans in development and to get involved in your watershed.

The Floodplain Viewer

The level of flood risk is related to how close your property is to a floodplain, a sump, or an inadequate path for overland relief. Use the Flood Risk Awareness Tool to view how these risk factors may affect your property and better understand your flood risk.

Fairfax County Government Center Campus Stormwater Management Facilities

A new interactive map is available to guide you along a walking tour of stormwater management facilities located on the Fairfax County Government Center Campus. On the walking tour, learn how ponds, a native meadow, a restored stream, bioretention areas, swales, green roofs, and permeable pavers collect runoff to control flooding, encourage detention and infiltration, and improve water quality.
