Annapolis floods more often than almost any town on the Chesapeake — its historic City Dock area floods on sunny days at high tide — and its centuries-old homes are slow to dry, making moisture a constant concern.
- Tidal ‘nuisance’ flooding hits the low historic district frequently, even without storms.
- Chesapeake surge from hurricanes and nor’easters adds severe flood risk.
- Historic homes hold moisture and dry slowly in the humid bay climate.
