Flooding Awareness & Mitigation

Flood Awareness
Like any other low lying coastal area, Norfolk's elevation and its proximity to the Chesapeake Bay and several rivers make it susceptible to flooding. Nearly every year, and sometimes several times throughout the year during periods of heavy rain, hurricanes or nor'easter storms, residential and commercial properties are threatened with the potential of precipitation, tidal and/or wind-driven flooding and/or low-land flooding, particularly in neighborhoods around Norfolk's many waterways.

Common Flooding Types and Definitions

  • Precipitation Flooding - Occurs when rain intensity exceeds capacity of our storm drain systems due to blockages or naturally depressed elevations.
  • Storm Flooding - Is caused by storm surges resulting from events such as hurricanes and nor'easters and is directly related to land elevation and proximity to coastline. High tides magnify this storm damage.
  • Tidal Flooding - Is caused by tidal variations and is directly related to land elevation and proximity to coastline. Tidal flooding may occur on a regular basis due to normal moon cycles and is exacerbated by wind speeds and directions, sea level rise, and other types of flooding.

Flood Mitigation
Flood Mitigation involves cost-effective measures taken now to avoid the loss of life and reduce future damages to public facilities, homes, and other improved property.  By implementing flood mitigation measures you may prevent future damage to your property resulting from flood and potentially lower your flood insurance premium.  You may want to consider discussing mitigation options with your flood insurance agent.  Additionally, should your property qualify the Hazard Mitigation Assistance (HMA) Grant Program may provide grant funds to assist with flood mitigation.
