More exposed than inland counterparts

Monmouth County (96.31) carries higher risk than Ocean County (96.15) to the north and substantially more than Morris County (92.88) inland. Its coastal location drives elevated flood and hurricane exposure compared to neighboring counties.

Coastal flooding and wildfires lead
