Connecticut Inland Wetland Soils

Connecticut Inland Wetland Soils

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, and floodplain by the National Cooperative Soil Survey, as may be amended from time to time, of the Natural Resources Conservation Service of the United States Department of Agriculture.”

Map units may be dominated by Connecticut inland wetland soils, but have inclusions of non-wetland soils. Non-wetland map units may contain inclusions of Connecticut inland wetland soils. On site investigation is necessary to determine the presence or absence of wetland soils in a particular area.
