Flooding is the nation’s most common natural disaster!  Currituck County can experience flooding from:

  • heavy rainfall
  • hurricanes
  • tropical storms
  • nor’easters

Heavy and prolonged rainfall can cause stormwater flooding.  Essentially, rain accumulates faster than soils can absorb it.

Low elevations, flat topography, high groundwater tables, and poorly drained soils further complicate stormwater flooding within the County.

Hurricanes and tropical storms can bring heavy rain and storm surge.  Storm surge and large battering waves from the Atlantic Ocean can result in:

  • loss of life
  • destruction of buildings
  • erosion of beaches and dunes
  • and damage to roads and bridges along the coast.

Storm surge can also occur along the Currituck Sound and Albemarle Sound depending on the angle at which a storm approaches the coast.  Storm surge values do not correspond well with hurricane wind categories. Tropical storms, category 1 or 2 hurricanes, major (category 3 to 5) hurricanes, and post-tropical cyclones can all cause life-threatening storm surge.

Flood maps were developed to communicate flood risk.  Knowing what your flood risk is can help you prepare before the storm.

It is important to remember that you are susceptible to flooding even if you do not live in a flood zone!
