m spread (p95−p5, ~20–40 km window)

The county center sits at about 184 m above sea level. Elevation across the sampled window spreads 744 m — mountainous terrain by our banding (flat <30 m · gently rolling 30–100 m · hilly 100–300 m · mountainous >300 m). Water covers about 27% 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.

Data available for Ketchikan Gateway Borough

• No free owner records. Alaska does not publish a free statewide parcel-and-owner dataset, so LandBenchmark cannot show who owns a parcel in Ketchikan Gateway Borough. 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 Ketchikan Gateway Borough. 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.
