Flood Zones and Floodplains

Before you purchase a property, check to find out if it is located in a Flood Zone, or Floodplain.  Most lenders require a property owner to purchase Flood Insurance if a property is located in a Floodplain.

Most everyone knows that coastal properties are subject to flooding and wind damage from hurricanes. Properties located within riverine watersheds are also subject to flood events. To find out more about flood-prone area maps, please reach out to the City of Baltimore Department of Planning at 410-396-7526.

If you are considering purchasing a property, it is a good idea to verify its flood hazard status before you commit to buy.

Floodplain Regulations

Most jurisdictions regulate construction and development in the floodplain to ensure that buildings are protected from flood damage. Filling and similar projects are prohibited in certain areas. Houses substantially damaged by fire, flood, or any other cause must be elevated to or above the regulatory flood level when they are repaired.

Flood Protection

A building can be protected from most flood hazards, sometimes at a relatively low cost. New buildings and additions can be elevated above flood levels. Existing buildings can be protected from shallow floodwaters by regrading, berms, or floodwalls. There are additional retrofitting techniques that can help protect a building from surface or subsurface water.
