Certified Local Governments

The National Park Service (NPS) and State Historic Preservation Offices (SHPOs) administer a certification process for municipalities to become recognized as a Certified Local Government (CLG). Becoming a CLG avails a municipality to funding opportunities and technical assistance from NPS and SHPOs. More information available from NPS, PHMC, and NJSHPO.
Local Historic Zoning Districts


While it is important to document a historic resource, determine its significance, and if appropriate, have it listed on the National or State Register of Historic Places, municipalities have more opportunity to protect a particular resource or maintain a community's character by enacting a local historic zoning district. In Pennsylvania, municipalities are afforded slightly more specific authority to regulate construction-related activities within a historic district under the Pennsylvania Historic District Act, referred to as Act 167.
Main Street Programs, Business Improvement Districts (BIDs), Special Services Districts (SSDs), and Special Improvement Districts (SIDs)


The national Main Street Program was started by the National Trust for Historic Preservation. The presence of a Main Street program often signifies a community's interest in preserving its historic resources, promoting its cultural resources, and maintaining or improving its livability. Business Improvement Districts (BIDs), Special Services Districts (SSDs) and Special Improvement Districts (SIDs), while not traditionally viewed as a historic preservation tool, often support and inspire historic preservation activities.
