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.

2019-2020 Map Updates

The Federal Emergency Management Agency (FEMA), which administers the NFIP, is in the process of updating its Flood INsurance Rate Maps (FIRMs).  The purpose of updating these products is to reflect new Base Flood Elevations (BFEs) and floodplain boundaries for Cumberland County communities.  Preliminary FIRM panels and Flood Insurance Study (FIS) are available for review on FEMA’s Map Service Center website.  As a result of the updates, some floodplain boundary areas will change, causing properties that were once outside of a floodplain area to be located within a floodplain area.

WHAT HAS CHANGED?

Floodplain boundaries have changed throughout the Township.  What this means for residents is that some properties currently identified in a Special Flood Hazard Area (SFHA) will be removed, while other properties currently in a lower risk zone such as “X” will now be in a SFHA.  The Township will send letters out to the affected property owners in the coming weeks.

ADDITIONAL INFORMATION

In upcoming months, Township staff and officials, Cumberland County staff, and representatives from FEMA will be working together to discuss and review the upcoming FIRM and FIS changes.  The Township will provide additional information to residents as it becomes available.  

FEMA &PEMA will be hosting a public open house event where residents will be invited to come view the maps and have their questions answered by FEMA staff.  Once FEMA announces the date and location of the event, we will post it here.

FEMA will also be holding a public comment period in late 2019/early 2020.  During the public comment period, residents will have the opportunity to submit technical and/or scientific data to file a protest regarding their individual property, or an appeal regarding the accuracy of the mapping process in general.  Once FEMA announces the public comment period, we will post it here.

This page will be updated as additional information becomes available.  Please check back periodically.

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.
