East Lyme, CTInc. 1839
East Lyme is a shoreline town on Long Island Sound east of New London, with a stretch of beach — including Rocky Neck State Park — that draws summer visitors. The housing stock ranges from the beach-area seasonal and year-round properties to suburban development along I-95 and Route 161 to the more rural inland sections.
For property professionals, East Lyme's coastal exposure along the Sound creates meaningful flood and storm risk for the shoreline properties, while the inland areas are more conventionally suburban. The I-95 corridor brings commercial property.
