In general, the sole basis for appeals is the possession of knowledge or information indicating that the proposed flood hazard determinations are scientifically or technically incorrect. Only appeals of the proposed flood hazard determinations supported by scientific or technical data can be considered before FEMA makes its final flood hazard determination at the end of the 90-day appeal period. However, FEMA also will consider comments and inquiries regarding data other than the proposed flood hazard determinations (e.g., incorrect street names, typographical errors, omissions) that are submitted during the appeal period, and will be incorporate any appropriate changes to the FIRM and FIS report before they become effective.

What Should Be Included In My Appeal?

Contact information (Name, Address, Phone, Email), specific location and identification of item being appealed, scientific or technical data to support your appeal.

What Will the Map Updates Include?

The Preliminary FIRM and FIS report include proposed flood hazard information for certain locations in the City of St. Charles. This may include additions to or modifications of Special Flood Hazard Areas, the areas that would be inundated by the base (1-percent-annual-chance) flood; base flood elevations or depths; zone designations or regulatory floodways.

Who Can Appeal?

Any owner or lessee of real property who believes his or her property rights will be adversely affected by the proposed flood hazard determinations.
