Floodplain Management

The Building Division is responsible for regulating development within the city’s floodplains based on the standards established by the National Flood Insurance Program (NFIP).

Special Flood Hazard Area (SFHA) development permits are required for all development in the SFHA. “Development” is defined in Title 44 of the Code of Federal Regulations as “any man-made change to improved or unimproved real estate.” Based on this definition, the following activities are subject to floodplain regulation:

  • Construction of new structures
  • Modifications or improvements to existing structures
  • Excavation
  • Filling
  • Paving
  • Drilling
  • Driving of piles
  • Mining
  • Dredging
  • Land clearing
  • Grading
  • Permanent storage of materials and/or equipment

The Building Division is also a repository for local Flood Insurance Rate Maps (FIRMs), the official documents used in determining whether a parcel or structure is located within a Special Flood Hazard Area. In addition to establishing areas regulated under NFIP standards for floodplains, these maps determine requirements and rates for flood insurance.

Paper copies of the maps, along with Letters of Map Change issued by the Federal Emergency Management Agency, are kept on file in the Building Division office. PDF versions of the maps are available for download below.

WEST WATER RUN, January 2020

The City of Grove City partnered with the Beulah Park developer, Falco, Smith & Kelley, to obtain a grant from the Ohio Public Works Commission to relocate the West Water Run stream onto the Beulah Park property. Because of the project and the submitted flood study, FEMA issued a Letter of Map Revision (LOMR) recognizing new floodplain boundaries and base flood elevations that affect many property owners along West Water Run. Some properties currently within the floodplain will be removed. For detailed plan information townload the West Water Run LOMR, effective Jan. 10, 2020, showing the changes.

MULBERRY RUN, March 2015
Based on a recent study of the Mulberry Run floodplain, the Federal Emergency Management Agency (FEMA) has issued a Letter of Map Revision (LOMR), effective March 12, 2015. The LOMR recognizes new floodplain boundaries and base flood elevations effecting many property owners along Mulberry Run. Some properties currently within the floodplain will be removed, while other properties now outside the floodplain will be within the floodplain.

This updated map could result in changes to the insurance rates and requirements for this property. You are advised to contact your lender or insurance agent to find out how you will be affected by these changes.
