​Pennsylvania Flood Maps

Whether you’re a property owner, industry professional, local official, or community, use the Federal Emergency Management Agency flood rate insurance maps to assess your area’s current flood risk.

For help determining future flood risk, preliminary digital versions of flood insurance rate maps are now available online. These new maps offer better functionality, accuracy, and accessibility, and are compatible with Geographic Information Systems — all features which make this type of map easy to use for planning, permitting, and insurance purposes.
