Difference between National Register and Local Historic Designation
In a nutshell: the National Register identifies; the local district protects.
The local historic district should not be confused with the National Register of Historic Places, which is a nationwide historic listing and functions primarily as an honorary designation. Alternatively, the local historic district is a district designated by a local ordinance which falls under the jurisdiction of the local historic preservation commission.
Both the National Register and the local historic district are used as effective preservation tools - both acting independently and cooperatively - to help preserve our community's rich historic resources.
