A real four-season New England climate

Glastonbury follows Connecticut's real four-season climate pattern, with cold winters and genuine seasonal variation typical of the Hartford region (base record).

Real Connecticut River floodplain exposure

A real, disclosed 10% of Glastonbury's own land area sits within the 100-year Connecticut River floodplain -- dated flooding affected South Glastonbury farmland as recently as July 2023, and an April 2017 flood warning closed the state ferry dock's seasonal opening (base record).

Modest, statewide tornado and nor'easter exposure

Connecticut's real, statewide modest tornado risk and genuine winter nor'easter exposure both apply generically to Glastonbury, consistent with this project's statewide Connecticut hazard research.
