Flood Hazard Information

Floods are among the most frequent natural hazards in New Jersey, and among the most devastating in terms of human hardship and economic loss.

The greatest risks occur in known flood plains when there is:

  • Intense rainfall over a  short period of time,
  • Prolonged rain over several days, and/or
  • Ice or debris jams causing river or streams to overflow.

Risks can occur anytime of the year.

  • Melting snow can combine with rain in the winter and early spring
  • Severe thunderstorms can bring heavy rain in the spring and summer
  • Hurricane or tropical storms can bring intense rainfall in the summer and fall.

Floods and Flash Floods each provide unique risks.

  • Floods develop over several hours or several days. Streets can become swift-moving rivers, creating great danger for pedestrians and drivers. Basements, buildings and entire swaths of land can become inundated, leading to deadly hazards, dangerous structural damage, and lost property or crops.
  • Flash Floods occur with little or no warning and are deadly and fast moving. They can begin within the first hours of a rain event, or after a dam or levee failure, or following the sudden release of water held back by an ice or debris jam. Their power can roll boulders, tear out trees, destroy buildings and bridges, scour out new channels and can also trigger catastrophic mudslides.

Wall Township is a participating community in the National Flood Insurance Program, flood insurance is available to all Township residents regardless of whether the home is in a Special Flood Hazard Area (SFHA) or not. Historically 25% of a flood insurance claims have been from structures outside the SFHA.

Flood Insurance Rate Maps (FIRM) commonly called Flood Maps
A FIRM is a map created by FEMA and the NFIP for floodplain management and insurance purposes.

A FIRM will generally show a community's base flood elevations, flood zones, and floodplain boundaries. As a property owner/renter, you can use this map to get a reliable indication of what flood zone you're in. However, maps are constantly being updated due to changes in geography, construction and mitigation activities, and meteorological events. Therefore, for a truly accurate determination, contact your insurance agent or company, or your community floodplain manager.
