FEMA Flood Zone & Wetlands Lookup Map
Here is the question I want every buyer and every seller to ask before a contract gets signed: is this parcel in a Special Flood Hazard Area, and does anything on it — wetlands, a drainage easement, a setback line — limit what you can build later? Pull both layers on the map below. Then read the Q&A underneath it, because the map tells you the zone; it does not tell you what the zone means for your closing.

What I actually get asked about flood zones and wetlands
I've been a broker in this market for about three decades, and I've watched more deals wobble at the flood determination than at almost any other single line item on the closing disclosure. Not because the zone was a surprise to me — because it was a surprise to the buyer, at week five of a thirty-day contract, with the lender's underwriter now asking for a number nobody budgeted for. So let's go through this the way I'd go through it with a client sitting across the desk: question, answer, and the caveat that actually matters.
When should you pull the flood determination — before you write the offer, or after?
Before. Every time. Your lender is going to order a Standard Flood Hazard Determination once you're under contract regardless, so the only question is whether you see the answer while you still have the option period to walk, renegotiate, or plan around it — or whether you see it after you've already waived contingencies and told your landlord you're moving. Pull the zone on the map above, or the FIRMette straight from FEMA's Map Service Center, the same day you decide to write. It costs you nothing and it costs you nothing to be wrong about.
Caveat: the map on this page and a FIRMette are a preliminary read. The determination your lender orders is the one that governs the loan. Use this to know what's coming, not to argue with the lender's paperwork.
What happens when the lender requires flood insurance and the buyer never priced it in?
This is the deal-killer I mentioned. If the home sits in Zone AE or VE and the loan is federally backed — FHA, VA, conventional through Fannie or Freddie — flood insurance is not optional, it's a condition of closing, and it gets escrowed into the monthly payment. If a buyer qualified at the edge of their debt-to-income ratio without pricing that premium in, the loan can get re-underwritten to a smaller amount, or the buyer has to bring more cash to close, or the deal dies. None of that has to happen. Get the flood insurance quote in writing during your inspection period, not after underwriting flags it.
Caveat: a private flood insurance quote and the standard NFIP premium can land in very different places. Get both quoted before you assume either number.
What is a LOMA or a LOMR, and could it get the insurance requirement removed?
A Letter of Map Amendment or a Letter of Map Revision is FEMA's process for correcting a flood zone determination — either because the structure sits on ground higher than the map shows, or because fill or drainage work has changed the actual flood risk since the map was drawn. If a property is mapped into Zone AE but an elevation certificate shows the lowest floor sits above the Base Flood Elevation, a LOMA can remove the mandatory insurance requirement entirely. I've walked sellers through this before a listing goes live, because a home that shows as "flood zone" on a portal search and turns out to have a LOMA on file is a very different conversation with a buyer.
Caveat: this takes a licensed surveyor's elevation certificate and FEMA review — it is not instant, and it is not guaranteed. Start it early if there's any reason to think the map is wrong for this specific lot.
How do wetlands on the parcel limit where you can build an addition or put in a pool?
This one surprises people because it has nothing to do with flood insurance. The USFWS wetlands layer and the setback rules enforced by the water management district are a land-use limit, not an insurance rating. A lot can be entirely out of the Special Flood Hazard Area and still carry a delineated wetland boundary that keeps a pool, a shed, or a room addition off part of the yard. If a buyer's plan for the property depends on building in the back third of the lot, check the wetlands layer before that plan gets baked into the offer.
Caveat: county permitting will run its own wetland delineation before issuing a building permit. The map layer here is your early warning, not the final word.
Why did my zone change since I bought the house — didn't FEMA already map this?
FEMA revises Flood Insurance Rate Maps periodically as flood modeling, development patterns, and drainage in an area change. A parcel that was Zone X at your purchase can be remapped into the Special Flood Hazard Area years later, with no change to the house at all — and sellers are routinely caught off guard by this at listing time, because their memory of "no flood zone" is a decade out of date. Always re-pull the current map before you list or before you make an offer. Don't rely on what the zone was when you bought.
Caveat: a map revision can also work in your favor — Zone AE to Zone X happens too, usually after drainage improvements. Either direction, verify current, not historical.
What do you actually do with this information once you have it?
Depends on what it shows. Zone X with no wetlands on the lot — build your offer with confidence and move on. Zone AE with a reasonable elevation certificate — price the insurance, confirm it against the DTI, and proceed with eyes open. Wetlands cutting through a lot you're counting on for an addition — redesign the plan or walk before you're emotionally attached. The point of pulling this before contract isn't to scare anyone off; it's to make sure the decision gets made on facts instead of getting made for you by an underwriter in week five.
Bring me the hard case — a parcel with a confusing zone boundary, an old LOMA you can't find, wetlands that might or might not touch the buildable envelope. That is exactly the kind of file I like working through before it becomes a problem instead of after.
This page is for general information only, not insurance, lending, legal, or tax advice. Flood zone determinations, mandatory-purchase requirements, and wetland boundaries depend on the specific parcel and change over time — confirm with FEMA's current maps, a licensed surveyor, and your insurance agent and lender before relying on them.

Have a parcel with a flood or wetlands question that isn't a simple yes or no?
Bring me the FIRMette, the elevation certificate, whatever you've got — I'll walk through it with you before you're under contract, not after.
