June MHAC Meeting

The City of Cambridge's Municipal Heritage Advisory Committee held an informational meeting on June 26, 2026, focusing on heritage retaining wall repairs and maintenance best practices. Two presentations were given regarding the conservation and repair of historic rubble stone retaining walls, including a specific project at the corner of Spruce and McNaughton streets involving partial rebuild and repointing using compatible lime-based mortars and grout. The discussion covered technical details of masonry wall construction, deterioration causes, repair methods, and preventive maintenance strategies to extend wall longevity. No votes or procurement decisions were made during the meeting, but the committee requested circulation of the detailed repair report for further review.
