The North Shore Management Board is a ten-member Joint Powers Board that contains a representative from all local units of government that exercise zoning authority on the North Shore of Lake Superior. Most members joined the NSMB when it was originally created in 1987. Silver Creek Township joined the NSMB in 1999 upon the creation of the zoning ordinance for the Castle Danger Subordinate Service District, which is administered by the Township. Lake County administers other areas within the North Shore Management Zone in Silver Creek Township.
