Letter of Final Determination

A Letter of Final Determination (LFD) is a letter FEMA mails to the Chief Executive Officer of a community stating that a new or updated Flood Insurance Rate Map (FIRM) or Digital Flood Insurance Rate Map (DFIRM) will become effective in six months. The letter also notifies each affected flood-prone community participating in the National Flood Insurance Program (NFIP) that it must adopt a compliant floodplain management ordinance by the map effective date to remain participants in good standing in the NFIP.

Hard Copy To Digital Enclosures For LFDs

As part of the ongoing FEMA effort to minimize hard copy (paper) distribution of flood hazard information, FEMA has discontinued the distribution of hard-copy enclosures with LFDs. The following documents, previously distributed in paper form with LFDs, are available digitally for viewing or download:

Although FEMA will no longer distribute paper copies of LFD enclosures, hard copies of these documents may be obtained by contacting the FEMA Map Information eXchange.
