Is Burlington County, NJ in a flood zone?
FEMA's National Risk Index puts Burlington County's flood hazard at the 96.4th percentile nationally — well above the national norm for flood hazard — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 3.2 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Who actually carries the flood insurance FEMA requires
Out of 4,044 homes FEMA counts inside Burlington County's mapped flood zone, 2,220 carry the flood policy federal law requires there — 54.9% compliance, short of full coverage. Across all residential structures in Burlington County, not just the ones FEMA mandates, 2.2% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
