Questions

Soils and wetlands screening note: what people ask

Is the national wetland map the legal wetland line?

No. The Wetlands Mapper uses a biological definition of wetlands and makes no attempt to set the limits of any regulatory program. Before work that could affect wetlands, the Fish and Wildlife Service recommends contacting your local Army Corps regulatory office.

Where does the soil data come from?

From the USDA NRCS soil survey. Web Soil Survey has soil maps and data online for more than 95 percent of the nation's counties and is maintained as the single authoritative source of soil survey information.

What counts as a wetland under federal rules?

Areas inundated or saturated by surface or ground water often and long enough to support, and that normally do support, a prevalence of vegetation adapted to saturated soil. Swamps, marshes and bogs are typical examples.
