Stretching from the southeastern shores of Lake Hopatcong to Route 80, Mount Arlington Borough is a small suburban residential community in Morris County. The borough includes quite a bit of preserved land mostly in the northern part of the borough, with a commercial area in the south centered around the Village Center, Howard Boulevard, and the Route 80 interchange. The Mount Arlington Train Station just south of Route 80 connects the region by train and bus. In 2011 the Highlands Council approved a petition from Mount Arlington to bring its local planning and regulatory documents into alignment with the Highlands Regional Master Plan (RMP), for the Preservation Area portion of the municipality only. The Highlands Council has since provided funding to the borough to support several planning initiatives.

Mount Arlington Borough is currently petitioning the Highlands Council for a review of its master plan and development regulations for alignment with the Highlands Regional Master Plan (RMP) in the Planning Area portion of the borough. The staff Consistency Review and Recommendations Report below provides an overview and analysis of this review. Comments on this petition were accepted from July 24 through August 24, 2025. It is anticipated that the Council will hold a public hearing on this petition at an upcoming regular public meeting.
