Collier County’s Flood Maps Are Changing: What Naples Property Owners Should Check Now

Collier County says its update to the Flood Insurance Rate Map is nearly complete. The county is targeting summer 2027 for the new map to take effect, and new flood insurance requirements would apply at that time. That date can still change, but the time to look up your property is now, because the formal appeal window is about to close.

Where Things Stand

FEMA released preliminary maps for Collier County on March 20, 2025. They are still preliminary, so the map in force today remains the one that took effect on February 8, 2024. The county’s August 19, 2026 announcement says a 90-day appeal period began that day. The announcement doesn’t name an end date, but 90 days from August 19 lands around November 17. If you think your property has been mapped incorrectly, call the county now to confirm the exact deadline.

How to Look Up Your Property

1. See the proposed map. Enter your address in FEMA’s preliminary map viewer or the Flood Map Service Center.
2. Compare it to today’s zone. The county’s Floodplain Management page links a FEMA tool that shows what changed between the current map and the proposed one.
3. Check for an elevation certificate. The same page explains how to see whether one is on file for your property.

What a Zone Change Could Mean

If you move into a high-risk zone (A or V): Lenders generally require flood insurance on federally backed mortgages in these zones. You would likely hear from your lender once the new map takes effect. Buying before then gives you time to compare options instead of reacting to a letter.

If you move out of a high-risk zone: Your lender may no longer require a policy, but your lender can still choose to. Lower risk isn’t no risk. Think carefully before canceling, since a storm surge or heavy rain event doesn’t stop at a line on a map.

If your zone stays the same: You still have useful information. Your zone and your elevation are worth reviewing when you renew or buy.

Does Your Flood Zone Set Your Price?

Not directly. FEMA’s current National Flood Insurance Program (NFIP) pricing looks at factors specific to your building, such as its distance to water, its elevation, and the cost to rebuild. The zone still matters because it drives the lender requirement. Private flood carriers set their own pricing, so it’s worth comparing both.

Unincorporated Collier County holds a Class 5 rating in FEMA’s Community Rating System. The county says that rating saves the community $9.6 million in premiums each year. If you live in the City of Naples or on Marco Island, ask your city’s floodplain office about its own rating and any local map questions.

If You Disagree With the Map

The county handles basic property verification and forwards comments and appeals to FEMA, which makes the technical decision. The county’s contact for appeals is Christopher Mason, Community Planning & Resiliency Division, at (239) 252-2932. An appeal generally needs technical support, so a licensed surveyor or engineer may be part of the process. The county also lists a separate Letter of Map Change process for structures that can show they sit above the flood level, which usually starts with an elevation certificate.

A Short Checklist

• Look up your address on the proposed map and the current map
• Find your elevation certificate, or ask about getting one
• Call the county soon if you think the map is wrong
• Ask us to compare flood insurance options, even if you aren’t required to carry it
• Plan ahead, since an NFIP policy typically has a 30-day waiting period
