Coastal Mapping

The effects of tides, combined with large amounts of water and waves from storms make coastal areas some of the most at-risk areas for flooding. To map coastal flood hazards accurately, many factors must be taken into account, such as the amount of development in the area, the types and strength of storms that historically have affected the area, and onshore and offshore elevations. 

Learn the steps involved to identify and map the coastal flood hazards shown on FEMA Flood Insurance Rate Maps (FIRMs). The FIRM is used to determine flood insurance requirements for residents and where floodplain development regulations apply in a community. 

Use the NJFloodMapper: An interactive mapping website to visualize exposure from coastal flooding hazards.
