Public-source readings for several addresses side by side

Type two to ten United States addresses to see what free public sources say about each spot: flood zone, wetlands, soil, elevation, a rough slope estimate, drainage catchment and land cover, side by side. Your browser contacts the government services directly and ABODE does not receive the addresses. It does not rank or score. You can print it or save a CSV file.

In short: Enter two to ten addresses to see flood zone, wetlands, soil, elevation, slope, drainage and land cover side by side, with no ranking. Print it or save a CSV.

Results

What did the public sources return for each address?

Results appear here as each address is read. Each reading shows its status; the limits of every source are listed below the table.

Each reading is context at one point from free public sources, not a determination. “Nothing mapped” is not “none”. ABODE does not rank, score or recommend among addresses. Parcel boundary and assessment, zoning, ownership, taxes, utilities, easements, permits and listing data are not part of these readings. They come from county and municipal offices and need their own checks. For decisions about a purchase, a build, septic, flood insurance or wetlands, ask the people who can look at the ground and the records: a licensed surveyor, a civil engineer or soil scientist, your insurance agent, the county planning and health offices, and your attorney.

Before you rely on it

What do these readings not tell you?

Each reading is background context at one point, not a flood determination, wetland delineation, soil or septic test, survey, inspection, appraisal or zoning opinion. “Nothing mapped” is not “none”. Parcel boundary and assessment, zoning, ownership, taxes, utilities, easements, permits and listing data are not part of these readings. They come from county and municipal offices and need their own checks.

Flood zone

FEMA’s map is not an official flood determination and does not replace a survey, an elevation certificate or an insurance quote. Preliminary and pending map data are not for rating insurance. A point with no mapped zone may simply be outside the mapped area. Source: FEMA National Flood Hazard Layer.

Wetlands

Wetlands are mapped from high-altitude imagery and can differ from conditions on the ground; not all wetlands are wet all year. The data shows type and extent by a biological definition and does not set any agency’s regulatory boundary. For regulatory questions contact the U.S. Army Corps of Engineers or the state agency. Source: U.S. Fish and Wildlife Service, National Wetlands Inventory.

Soil map unit

Soil survey map units are broad averages for an area, not a test of this site. This is not a septic, foundation or building suitability determination. Some areas have no completed survey. Source: USDA NRCS Soil Survey Geographic Database (SSURGO).

Elevation

Elevation is read at one point from USGS 3DEP, whose resolution varies by area. It is not a survey and says nothing by itself about slope across a parcel. Source: USGS 3D Elevation Program.

Ground slope estimate

Slope here is an estimate from five elevation readings around one point, not an average across the parcel and not a survey. Elevation resolution varies by area and small errors matter over short distances. It says nothing about whether anything can be built. Source: USGS 3D Elevation Program, computed by ABODE from five readings.

Drainage catchment

The catchment is a drainage-area reference number from the USGS hydrography network, found by a point lookup. It does not show how far a stream is, whether water reaches the property, flood risk or water rights. Source: USGS Network-Linked Data Index.

Land cover

Land cover is a satellite-based estimate on 30-meter cells (annual NLCD). A cell can be wrong, and a mixed cell shows one class. It is not a zoning, land-use or tree-health finding, and it does not mark a parcel boundary. The nine samples are a coarse look at the surroundings, not an area measurement. Source: USGS Annual National Land Cover Database (NLCD 2025).

Location

Coordinates come from the U.S. Census Bureau address locator and can be off for rural addresses. They are not a parcel boundary.

For decisions about a purchase, a build, septic, flood insurance or wetlands, ask the people who can look at the ground and the records: a licensed surveyor, a civil engineer or soil scientist, your insurance agent, the county planning and health offices, and your attorney.

Questions

Compare addresses: frequently asked questions

Does the comparison rank or score the addresses?

No. It shows the readings side by side and nothing more. A difference in a flood zone, slope or land-cover reading is not a statement that one property is better or worse. Which matters depends on your plans and on what professionals find on the ground.

Where do the addresses I type go?

Your browser sends each address directly to the U.S. Census Bureau and then sends the coordinates it returns to FEMA, the U.S. Fish and Wildlife Service, USDA and USGS. ABODE does not receive, store or log the addresses or the results.

Why does it read one address at a time?

The government services share capacity with everyone, and asking for several addresses at once can make them drop requests. Reading one at a time is slower but more complete. Expect a minute or two for five addresses.

What is in the downloaded CSV file?

One row per address with the matched address, county, coordinates, each reading with its status, the date read and the sources. The file is made in your browser and saved to your computer. ABODE does not receive it.

Private consultation

Ask an advisor about what you found

Do not include the addresses you compared unless you want us to see them. An ABODE advisor replies privately. We aim to reply within one business day.
