Name: U.S. Congressional Districts Channelization

Display Field: District

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This layer is comprised of Congressional Districts categorized based on the intesity of channelization within each district (a percentage of the length of all streams that has been channelized) into 'Low', 'Medium', and 'High' categories.
