FEMA Floodplains


The Township participates in the National Flood Insurance Program of the Federal Emergency Management Agency (FEMA). By including FEMA’s floodplain development regulations in our Zoning Ordinance, we assure that Township property owners are able to secure flood insurance and that overall risk of property damage due to flooding is reduced, as the regulations control development in flood-prone areas. Flood Insurance Rate Maps, or “FIRMs", identify properties that are totally or partially within the 100-year floodplainVirtually all mortgage lenders now require their customers who own properties in flood-prone areas on the FIRM to procure flood insurance as a condition of approving a mortgage or home equity loan.

FIRMs identify flood risk using a combination of detailed studies and estimates based upon topographic mapping and aerial photography. FEMA updates the FIRMs in our area approxi­mately every ten years. The updates show changes to the extent of flood-prone areas due to changes in topography caused by new development as well as new detailed studies and new predictive flood models.

Township Regulations

The current FIRMs for West Whiteland Township were adopted in 2017. You can view the maps by clicking on “Interactive FIRM Map” below. Along with the FIRMs, the Township has adopted FEMA's recommended floodplain regulations. The regulations prohibit all development in floodplain areas unless the property owner has secured a variance from the Township’s Zoning Hearing Board.
