m spread (p95−p5, ~20–40 km window)

The county center sits at about 200 m above sea level. Elevation across the sampled window spreads 174 m — hilly terrain by our banding (flat <30 m · gently rolling 30–100 m · hilly 100–300 m · mountainous >300 m). Water covers about 2% of the county's area (Census Gazetteer). These are county-scale context, not parcel measurements — a specific parcel gets its own slope, flood and usable-acreage readings when analyzed.

Elevation measured 2026-07-21 from the AWS Terrain Tiles (terrarium encoding, z10).

Data available for Hunterdon County

  • No free owner records. New Jersey does not publish a free statewide parcel-and-owner dataset, so LandBenchmark cannot show who owns a parcel in Hunterdon County. The county assessor's office is the authoritative source. Every measured signal below is unaffected.
  • No township/range legal description. New Jersey is a metes-and-bounds state with no PLSS grid.
  • FEMA flood zones, wetlands, soil survey and NCCPI soil productivity — the federal layers, all free and all available here.
  • 56 measured signals from satellite imagery and public records — slope and usable acreage, observed surface water, vegetation trend, wildfire and seismic hazard, access and neighboring land use. Each one cites its method, its source, and the date it was observed.

LandBenchmark has no listings and does not know what is for sale in Hunterdon County. It analyses a parcel you point it at. It is an automated Phase-1 desk screen, not a survey, a flood determination, or a substitute for on-site inspection.

Common questions about land in Hunterdon County

Can I see who owns a parcel in Hunterdon County?

Not from free data — New Jersey does not publish a free statewide parcel-ownership dataset, and LandBenchmark does not buy broker data. The Hunterdon County assessor's office is the authoritative source; every measured signal is unaffected.

How hilly is Hunterdon County?

Around the county center, measured elevation spreads 174 m across a ~20–40 km window — hilly terrain by our banding. Individual parcels vary: a report measures the actual slope and usable acreage of the parcel you point it at.

What can LandBenchmark measure for a parcel in Hunterdon County?

56 measured signals, each cited with source and observation date: FEMA flood zone plus surface water observed in multi-year imagery, USFWS wetlands, USDA soil survey and productivity, slope and usable acreage, wildfire and seismic hazard, access and surroundings. What a satellite cannot verify — title, zoning, perc results, water rights — goes on a human-verify checklist naming the Hunterdon County offices that can.
