Statewide downtown revitalization program for communities that seek designation as Main Street communities. The Main Street movement has been transforming the way communities think about the revitalization and management of their downtowns and neighborhood commercial districts for decades. Specifically, Main Street is three things: a proven strategy for revitalization, a powerful network of linked communities, and a national support program that leads the field. The National Main Street Center is a subsidiary or the National Trust for Historic Preservation.
