  • Nothing saved
  • FEMA, USDA, USGS and NREL data

Standing on the land? Use your location. Every check is free and nothing you look up is saved.

What it checks

Five checks, five public sources.

Flood zone

FEMA National Flood Hazard Layer

The flood zone at the exact point, what it means for insurance and permits, and the base flood elevation where FEMA publishes one.

Septic and soil

USDA NRCS soil survey

How the soil rates for a septic drain field and why, plus drainage, seasonal water table, depth to bedrock, slope and farmland class.

Elevation

USGS 3D Elevation Program

Height above sea level, which sets your growing season and snow load.

Solar

PVWatts, National Laboratory of the Rockies

How much power each kilowatt of panels makes here in a year, and the darkest month you would size an off-grid system for.

Parcel

State parcel records

The owner of record, size and parcel ID, in the 13 states whose parcel data we map.

FAQ

Flood zones, soils and perc tests, answered.

Search the address above. The report reads FEMA’s National Flood Hazard Layer at that exact point and tells you the zone in plain English. For the official map panel to show a lender, use the FEMA Flood Map Service Center at msc.fema.gov.

Zone X is outside FEMA’s high-risk area. Shaded Zone X is the 0.2 percent annual chance (500-year) floodplain, and unshaded Zone X is minimal risk. Zones that start with A or V are Special Flood Hazard Areas, where lenders require flood insurance.

Many rural counties have no digital flood map. That means the risk was never studied, not that there is none. Walk the property for creeks, washes and low ground, and ask the county floodplain manager.

Only a perc test answers that, but the USDA soil survey gives a good first read. The report shows the soil’s rating for a septic drain field (not limited, somewhat limited, or very limited) and why, such as a high water table or shallow bedrock. Very limited usually means an engineered system instead of a standard drain field.

The USDA Natural Resources Conservation Service has mapped the soils of nearly every county in the country. Each soil comes with tested properties: drainage, depth to the water table and to bedrock, slope, and ratings for uses like septic fields and building sites. This report pulls those for the exact point you search, the same data Web Soil Survey shows.

Yes, it is free, with no account. Your browser asks each government service directly and nothing you look up is stored. The link in your address bar opens the same report, so you can send it to a partner or a builder.
