Westport, CTInc. 1835
Westport is one of Connecticut's most affluent communities, with a Long Island Sound coastline, a vibrant downtown, and a housing stock that ranges from waterfront estates to close-in colonial neighborhoods to the more rural properties in the northern sections. The Saugatuck River runs through the center, creating the Saugatuck commercial district and environmental features.
For property professionals, Westport is a premium market with significant coastal exposure, high assessed values, and the kind of variation — waterfront to inland, estate to village — that requires parcel-level data. The Sound coastline brings flood zones and storm risk that affect a meaningful share of properties.
