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.
