Public Invited to Review Flood Maps in Montour County, PA

Release Date Release Number
Release Date:
July 15, 2021

FEMA is proposing updates to the Flood Insurance Rate Maps (FIRMs) in the Borough of Danville and Township of Mahoning in Montour County, Pennsylvania. Community partners are invited to participate in a 90-day appeal and comment period.

Because flood risk changes over time, flood maps are routinely updated to represent flood risk more accurately. In this case, updates were made in response to the extensive flooding seen during Tropical Storm Lee in September 2011. For more background information on this mapping update, visit: https://www.fema.gov/pennsylvania/mitigating-flood-risk

The updated maps were produced in coordination with local, state and FEMA officials. Significant community review of the maps has already taken place, but before the maps become final, community partners can identify any corrections or questions about the information provided and submit appeals or comments.

The 90-day appeal period will begin on July 15, 2021. Residents, business owners and other community partners are encouraged to review the updated maps to learn about local flood risks and potential future flood insurance requirements. They may submit an appeal if they perceive that modeling or data used to create the map is technically or scientifically incorrect.

  • An appeal must include technical information, such as hydraulic or hydrologic data, to support the claim.
  • Appeals cannot be based on the effects of proposed projects or projects started after the study is in progress.
  • If property owners see incorrect information that does not change the flood hazard information—such as a missing or misspelled road name in the Special Flood Hazard Area or an incorrect corporate boundary—they can submit a written comment.

Appeals and comments may be submitted by contacting your municipality’s floodplain administrator. The next step in the mapping process is the resolution of all comments and appeals. Once they are resolved, FEMA will notify communities of the effective date of the final maps.

The preliminary maps may be viewed online at the FEMA Flood Map Changes Viewer: http://msc.fema.gov/fmcv. Changes from the current maps may be viewed online at the Susquehanna River Flood Map Viewer: https://arcg.is/1CLSan.

For more information about the flood maps:

  • Contact a FEMA Map Specialist by telephone; toll free, at 1-877-FEMA-MAP (1-877-336-2627) or by email at FEMA-FMIX@fema.dhs.gov.

Most homeowner’s insurance policies do not cover flooding. There are cost-saving options available for those newly mapped into a high-risk flood zone. Learn more about your flood insurance options by talking with your insurance agent and visiting https://www.floodsmart.gov.
