m spread (p95−p5, ~20–40 km window)

The county center sits at about -1 m above sea level. Elevation across the sampled window spreads 11 m — flat terrain by our banding (flat <30 m · gently rolling 30–100 m · hilly 100–300 m · mountainous >300 m). Water covers about 70% 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 Plaquemines Parish

• No free owner records. Louisiana does not publish a free statewide parcel-and-owner dataset, so LandBenchmark cannot show who owns a parcel in Plaquemines Parish. The county assessor's office is the authoritative source. Every measured signal below is unaffected.
• Legal description — township, range and section from the BLM Public Land Survey System.
• 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 Plaquemines Parish. 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.
