Tracking 4,043 properties across Monson, Massachusetts — a community where the median home dates to 1973 and the oldest to 1715. Every parcel mapped with building characteristics, environmental exposure, hazard risk, and ownership history assembled from 140+ sources.
Monson is a small town in the southeastern part of Hampden County, notable for hosting Monson Academy (now the Wilbraham & Monson Academy) and for being struck by an EF-3 tornado in June 2011 that caused significant damage to the town center. The rebuilding has changed portions of the housing stock.
For property professionals, Monson's tornado history is a relevant factor — the 2011 storm damaged or destroyed numerous properties, and the rebuilding created a mix of pre-tornado older homes and post-tornado new construction within a small area.
