The purpose of this district is to recognize the historic residences and related structures situated along Route 173 at the southern portion of the Township. These are single-family homes which are listed in the New Jersey State Historic Preservation Inventory. Some are currently in the ROM Research Office Manufacturing Zone, while others are in the RCD Residential Conservation District. It is the intent of this section to place these properties in a zone district that relates to their unique setting and historic character and contains appropriate regulations. Most are served by public water. The Musconetcong River, a "Wild and Scenic River," forms the southern boundary of the district.
