Below is the process and more information about how a FIRM goes from assessment to final determination.
FEMA conducts an assessment too determine if a new Flood Insurance Rate Map (FIRM) is required. If necessary, engineers will reevaluate flood zones and develop a new FIRM using LiDAR technology and GIS.
2. Flood Risk Review
After FEMA conducts a Flood Risk Review (FRR), results are shared with the community through a presentation and an introduction of the draft FIRM at an FRR meeting. Feedback is collected.
3. FIRM Goes “Preliminary”
Using data and feedback, the new FIRM is finalized. The effective date for the map is determined. Changes after this step will require formal appeals.
4. CCO Meeting
The Community Coordination Outreach (CCO) meeting is held to present local officials with the effective map and to discuss the accompanying Floodplain Ordinance, a 90-day appeals window opens and the local government is given six months to formally adopt the Floodplain Ordinance.
5. Pre-LFD/Open House Meetings
The public is invited to view effective maps and ask questions about the Floodplain Ordinance at the Pre-LFD Meeting. The “open House” meeting is optional and can occur before or after the Letter of Final Determination (LFD).
