Floodplain Information

About Us

The City of Harrisburg has a long history with our waterfront along both the Susquehanna River and Paxton Creek; a connection that has complemented (by enabling and supporting industry and recreation) and complicated (major flooding events) development in the city. In order to improve its management of these natural resources and their adjacent land – what is known as the Special Flood Hazard Area (SFHA) or the 100-Year Floodplain – the City entered the National Flood Insurance Program’s (NFIP) Community Rating System (CRS) program.

In exchange for voluntarily managing development in the SFHA in excess of the minimum NFIP requirements, owners of property in the floodplain receive discounts on their flood insurance. Currently, the City of Harrisburg is a Level 6 community, meaning property owners in the 100-Year (AE, A & AO zones) floodplain receive a 20% discount on their flood insurance, and owners of property in the 500-Year (Zone X) floodplain receive a 10% discount on their flood insurance.
