The State of Connecticut defines inland wetlands based on soils.

The Connecticut Inland Wetlands and Watercourses Act defines wetland

soils to include any of the soil types designated as poorly drained,

very poorly drained, alluvial, or floodplain by the National Cooperative Soil Survey,

as may be periodically amended, of the Natural Resources Conservation Service

of the United States Department of Agriculture.

Map units dominated by Connecticut inland wetland soils may have inclusions

of non-wetland soils, and non-wetland map units may have inclusions of

Connecticut inland wetland soils. On site investigation is necessary to

determine the presence or absence of wetland soils in a particular area.

This data set is a digital soil survey and generally is the most

detailed level of soil geographic data developed by the National

Cooperative Soil Survey. The information was prepared by digitizing

maps, by compiling information onto a planimetric correct base

and digitizing, or by revising digitized maps using remotely

sensed and other information.

This data set consists of georeferenced digital map data and

computerized attribute data. The map data are in a soil survey area

extent format and include a detailed, field verified inventory

of soils and miscellaneous areas that normally occur in a repeatable

pattern on the landscape and that can be cartographically shown at

the scale mapped. The soil map units are linked to attributes in the

National Soil Information System relational database, which gives

the proportionate extent of the component soils and their properties.
