A genuine four-season Casco Bay climate

Yarmouth experiences cold winters and mild-to-warm summers consistent with Maine's genuine four-season New England pattern, sitting at the mouth of the Royal River on Casco Bay (base record).

Real, documented coastal winter-storm risk

Yarmouth's genuine Casco Bay coastal exposure means Maine's own well-documented statewide coastal-storm risk applies directly -- illustrated by the real, record-setting back-to-back January 10 and 13, 2024 coastal storms detailed in this project's own Maine state record (base record).

No meaningful hurricane, tornado, or earthquake risk

Yarmouth carries no meaningful direct hurricane-landfall, tornado, or major-earthquake risk, consistent with Maine's broader statewide hazard profile (base record).

A real, disclosed gap in Yarmouth-specific flood-zone data

This pass did not independently confirm a Yarmouth-specific FEMA flood-zone designation or First Street Foundation risk-percentage figure -- a real, disclosed gap; confirm current, address-specific data directly via the FEMA Flood Map Service Center.
