Preliminary Jefferson Parish FEMA Flood Maps Now Available For Public Comment

Jul 3, 2013

The Federal Emergency Management Agency has released new preliminary flood maps for Jefferson Parish, and are asking the public to participate in a 90-day comment period.

Flood maps are created by FEMA, in conjunction with the Army Corps of Engineers and local officials, and are used to calculate flood risk and determine flood insurance rates. The public comment period is an opportunity for residents, renters and business owners to review the maps and comment on them file appeals — the agency will accept public comment until September 30.

The Jefferson Parish maps cover the incorporated cities of Gretna, Harahan, Kenner and Westwego; the Towns of Grand Isle and Jean Lafitte; and the unincorporated areas of the parish.

Maps are available for review at:

More information about the maps is available at:

FEMA says map appeals are formal objections that must be based on technical data that show the maps are scientifically incorrect. Problems with features of the maps themselves — such as labels, road names and jurisdictional boundaries — are not appealable, but can be formally commented upon.

Comments and appeals can be made to the local FEMA floodplain administrator at 1-877-FEMA MAP (1-877-336-2627), or by email at

FEMA will announce the effective date of the maps once all comments and appeals have been received.
