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.
The following map units meet the definition of Connecticut inland
