After months of collaboration and the continuous sharing of information resulting in preliminary flood maps, officials with Collin County and the Federal Emergency Management Agency (FEMA) are now asking the public to participate in a 90-day comment period.

Homeowners, renters and business owners in the cities of Allen, Dallas, Fairview, Frisco, McKinney, Plano, Richardson and the unincorporated areas of Collin County are encouraged to view the preliminary flood maps to better understand where flood risks have been identified.

Those with comments or who would like to file an appeal have until Dec. 19 to do so. 

An appeal is a formal objection to proposed base flood elevations or flood depths, Special Flood Hazard Areas (SFHA) boundaries and zones or floodways.

Appeals must be based on technical data that show proposed maps to be scientifically incorrect. Anyone who makes an appeal must include the method, data and analysis used to support the claim. 

A comment is an objection to a base map feature change such as labels, incorrect roads, jurisdictional boundaries, or any other non-appealable change.

Comments and appeals should be sent to FEMA through the local floodplain administrator. Anyone who hasn't had a chance to participate in local flood insurance meetings or to review the new flood maps is encouraged to contact their county or community floodplain administrator.

Once all comments and appeals are resolved, FEMA will notify communities of the effective date of the final maps.
