Layer: NRCS Predominantly Hydric Soil Map Units (ID: 176)

Parent Layer: Wetland Land Use Notification

Name: NRCS Predominantly Hydric Soil Map Units

Display Field: AREASYMBOL

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: NRCS Predominantly Hydric Soil Map Units prepared from USDA NRCS SSURGO data. Extent of mapping is limited to the Portland Urban Services Area and West Hayden Island. The Portland Urban Services Area includes portions of Multnomah, Clackamas, and Washington Counties. The Predominantly Hydric Soil Map Units layer dsiplays all map units where "Percent Hydric" (HydrcRatng) entry is greater than 50 percent. This shows map units with over 50 percent soil components meeting NRCS hydric soil criteria. These areas do not show where wetlands are, but where most soil components tend to be saturated, inundated, or flooded for long periods of time, thus increasing the potential that wetlands may develop in these areas. This layer is provided as a screening tool for those areas where wetland mapping may be lacking, incomplete, or inaccurate. In all cases actual field conditions determine the presence and extent of wetlands.
