Abstract:
This data represents established channel lines under Westchester County jurisdiction.  County channel lines are established along entire lengths or sections of rivers and streams that are administered and maintained by County Department of Public Works.
Purpose:
This data is used to determine if a municipal planning action (such as zoning or site plan approval) should be referred by the municipality to the County Planning Board for review and comment per mandatory referral provisions of both Westchester County Administrative Code and New York State General Municipal Law, based on the action's proximity to these channel lines.
