Colored points represent public assets located within the selected floodplain.
This analysis evaluates public asset exposure to flooding under current and future conditions using floodplain datasets developed by Rutgers University and the New Jersey Department of Environmental Protection (NJDEP). Flood scenarios represent water-level–based flooding only and do not include rainfall-driven runoff, stormwater ponding, or sewer system impacts.
Public asset locations were buffered by 100 feet to account for building footprints, access constraints, and localized service disruption beyond a single point location. Assets were classified as exposed if their buffered area intersected either floodplain.
New Jersey's Blue Acres program, administered by the Department of Environmental Protection, purchases flood-damaged and flood-prone properties and permanently converts them to open space. It is one of the most effective tools government has to reduce repetitive flood losses, lower future disaster costs, and protect communities. By removing vulnerable structures from the floodplain, Blue Acres restores natural flood storage, reduces risk for remaining residents, and demonstrates what proactive government intervention can look like at scale. Green parcels on the map represent properties already acquired statewide.
