Maryland home risk profile

You're flying into BWI on Friday, you've got a Sunday deadline on a house in Ellicott City or Annapolis, and someone — your agent, your lender, a neighbor — just said the words "flood history." That's the moment this page is for. Maryland doesn't hand out one hazard. It hands out two or three depending on which side of a creek, bay, or ridge you land on.

Flooding is the one to take seriously — a 4 out of 5. The Chesapeake Bay shoreline, the tidal rivers feeding it, and the flashy small streams inland all show up on FEMA flood maps. FloodSmart will tell you whether the address sits in a Special Flood Hazard Area, and your lender will tell you whether insurance is mandatory. In many Maryland counties, it is. Read the elevation certificate before you read the inspection report.

Behind flooding, extreme heat sits at a 3 out of 5, and it's the rating that surprises buyers the most. Summers in Baltimore and the DC suburbs are humid and hot enough that the CDC tracks heat as a genuine health risk, not a comfort complaint. Winter storms also rate 3/5 — think ice more than snow — and hurricanes and severe thunderstorms land at the same level, mostly as wind, rain, and power-outage events rather than direct hits. Tornadoes and drought sit lower at 2/5; wildfires, earthquakes, and landslides are effectively 1/5, rare enough that you can file them under "not your first concern."

The Maryland Department of Emergency Management runs the statewide response and publishes the hazard plans worth skimming. If you only have one evening before closing, spend it on the flood zone and the elevation certificate. Everything else on this list can wait until after you own the place.
