How njflood.zone works

A quick walkthrough — takes about 30 seconds.

1

Enter any NJ address

Type in a New Jersey address and select it from the dropdown. Works for any property — homes, businesses, vacant land.

2

Get instant flood zone results

We check FEMA's National Flood Hazard Layer and return your flood zone in seconds. No signup, no cost.

Zone X
✅ Not in a flood zone
Zone AE
⚠️ High-risk flood zone
3

See how close you are

Not in a flood zone? We show exactly how far away the nearest one is — in feet or miles. In a flood zone? We show the nearest safe area.

💡 Even if you're in Zone X, being close to a flood boundary is useful info for insurance and buying decisions.
4

Interactive map with flood overlay

See FEMA flood zones rendered on a live map centered on your property. Zoom in and out to explore the area. Blue and red shading shows flood-prone areas.

5

Elevation profile

A smooth terrain profile shows the elevation between your property and the nearest flood zone (or safe zone). See if you're higher, lower, or level.

📐 Properties higher than the flood zone are naturally safer — even if they're technically close.
6

Flood & sea level simulator

Toggle between flood intensity and sea level rise, then drag the slider to watch zones expand. Try it:
