Elevation data for Mercer, Burlington, Camden and Gloucester counties will be 9 years old at the time of the proposed spring 2024 collection. NJ has experienced significant storm events that have impacted the area, and there has been a significant amount of urban development and an increase in population in these counties; which modifies the elevation profiles.

Updated elevation data will result in more accurate flood modeling, as well as resiliency and flood hazard planning. LiDAR data is also being increasingly used for developing other data sets such as building footprints, impervious surface maps, solar potential estimates, tidally referenced shorelines, and marsh migration and carbon sequestration models.

This is an estimate. An official schedule has not been released.
