Layer: Channel Subject to Migration (ID: 0)

Name: Channel Subject to Migration

Display Field: NAME

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: This dataset represents segments of water courses in Snohomish County that are associated with channel migration zones (CMZ). The CMZ-Rivers layer identifies the rivers and streams in Snohomish County where there is a possibility for channel migration to occur due to the forces of erosion and deposition (also referred to as the erosion hazard area). The areas adjacent to these rivers are potentially at a high risk of occupation by a river channel within next 100 years. The layer does not show the lateral extent of the channel migration zone, only the linear geographic extent where significant channel migration could occur. The detailed methodology for determining the lateral extent of the CMZ is contained in Section 2 of the Washington DNR Forest Practices Board Manual [WAC 222], adopted by reference in Section 30.62B.330(2)(a) SCC.
