Floodplain Management

National Flood Insurance Program (NFIP)

Upper Allen Township is a participating community in the National Flood Insurance Program (NFIP). As such, the Township agrees to abide by federal rules and regulations designed to protect the community from some effects of flooding.

Several areas within the Township are located within federally recognized floodplains and are subject to restrictions on development and use. In return for our participation in this program, property owners are eligible to obtain flood insurance from the federal government (typically issued through an independent insurance broker).

Since the Township participates in the NFIP, we are required to govern regulations regarding development in floodplain areas. Chapter 245, Article XVII of the Township Zoning Ordinance identifies what restrictions apply when developing within a floodplain.

Please check with the Community Development Department before beginning any work in a floodplain or near any waterways such as creeks and streams. If your project does involve development in the floodplain, a Supplement to Building Permit Application Form must be submitted with your building or zoning permit application.

2009 Map Updates

The Federal Emergency Management Agency (FEMA), which administers the NFIP, compiled updated maps for Cumberland County in 2009.  FEMA used modern technology to better identify the location of floodplain boundaries, which are shown on Flood Insurance Rate Maps (FIRM).

As a result, some floodplain boundary areas changed causing properties that were once outside of a floodplain area to be located within a floodplain area.
