Zoning
VR-1
Village Residential 1 District
This residential district encompasses the existing village section of Glen Gardner which is characterized by existing dwellings on small lots. It is predominantly an historic and man-made environment. The intention is to create a village with a mix of single-family and two-family residences on small lots at an average density of approximately four dwelling units per acre, along with municipal uses which reinforce the historic residential character of the area. Any new development without public water and sewer would be required to have a minimum lot size of one acre. This area is designated as a potential historic district and contains design standards oriented toward the preservation of historic structures.
