USDA Soil Type by Address

See what USDA soil survey data says about a specific U.S. property. Find its mapped soil unit, then explore soil components, texture, drainage, hydrology, restrictive layers, and survey indicators.

One address. Multiple layers.

From a street address to an evidence-linked soil profile

The lookup preserves the distinctions USDA makes between a mapped polygon, a map unit, and the soil components associated with that unit.

01 · Place

Confirm the mapped point

The Census match appears on a draggable map before any soil claim is made.

02 · Polygon

Locate the SSURGO unit

A point-in-polygon query identifies the USDA map unit surrounding the selected coordinate.

03 · Profile

Read every component

Percentages, horizons, hydrology, restrictions, and missing values remain visible and traceable.

Built for honest interpretation

A map unit is not a single scoop of soil

USDA map units often contain several named components. The dominant component is not guaranteed beneath a house, garden bed, or proposed drain field. We show the composition instead of collapsing it into false certainty.

No ZIP-code shortcut

The selected latitude and longitude are resolved against an actual SSURGO polygon.

No fabricated zeroes

Missing USDA values are labeled “Not reported,” because absent data does not mean zero.

No invented risk score

Flooding, ponding, hydric status, and drainage retain source classifications and limitations.

Common questions

What the lookup can—and cannot—tell you

Does this identify the exact soil beneath my house?

No. It identifies the USDA map-unit polygon at the point and displays the soil components associated with that mapped unit. Field conditions can vary.

Is Ksat a septic perc test?

No. Saturated hydraulic conductivity is a soil-survey estimate of saturated transmission. It is not a parcel infiltration test or septic percolation test.

Why is a value not reported?

Some attributes are absent or not applicable in a USDA record. The interface preserves that state instead of substituting zero.
