Understanding NJ’s Resilience to Storm Events Through the Use of Mobile-based LiDAR Data

The combination of Hurricane Irene and Superstorm Sandy over such a short period of time was a game changer for many New Jersey communities. With Hurricane Irene, historic inland flooding throughout the State had prompted planners and water resource managers working in riparian areas to pay focused attention on measures that could be implemented to mitigate high impact flooding from regularly occurring storm events. Center staff along with faculty and students from Civil Engineering at Rutgers University with acknowledgements to the New Jersey Department of Environmental Protection and the New Jersey Office of Emergency Management, developed a 3D elevation model of all homes, businesses and infrastructure in Ocean County shoreline communities located within current A and V Zones of the FEMA Preliminary Flood Insurance Rate Maps (FIRMs). An online viewer was developed to visualize the mobile-based LiDAR that was collected in these areas. First floor estimations were then calculated and examined against existing elevations from an individual property’s elevation certificate. These data can then be viewed alongside previous damage data (NFIP, Substantial Damages) and projected flood hazard data to understand which properties are at risk from future storm events. This work is currently being extended into the Raritan River area through the award of a Rutgers Raritan River Consortium mini-grant.
