Flood Zones and Flood Insurance in the Sacramento Region
How to look up a Sacramento-area address on FEMA's flood map, what the zones mean, when a lender requires flood insurance, and what living behind a levee means.
Why does flood risk matter so much in Sacramento?
Sacramento sits where the Sacramento and American rivers meet, and much of the region is protected by levees. That's why flood risk comes up in so many sales here, even in neighborhoods that have never flooded in anyone's memory.
The Sacramento Area Flood Control Agency (SAFCA) and Sacramento County publish maps of hypothetical levee breaks. The county's flood scenario page (checked October 22, 2026) covers four zones: Natomas, American River North, American River South and the Delta. The American River South maps include the Pocket. The county reminds readers these are scenarios, not forecasts.
None of this means you shouldn't buy or own a home here. It means you should look up the address, know what the map says, and decide about insurance with your eyes open.
How do you look up a home's flood zone?
Two free tools cover most of what you need:
- FEMA's Flood Map Service Center (msc.fema.gov). FEMA's homeowner page (last updated November 18, 2025) says to type in your address and open the dynamic map to view your FIRMette, a printable piece of the official flood map.
- MyHazards from the California Governor's Office of Emergency Services (myhazards.caloes.ca.gov). Enter an address to see natural hazards for that location.
Inside Sacramento city limits, the city's Floodplain Information Line is (916) 808-5061, listed on the city's Natomas floodplain page. When you're buying, the lender will also order a flood zone determination as part of the loan. If that result surprises you, tell us right away. It can change your monthly cost.
What do Zone A, AE, A99 and X mean?
FEMA's flood zones glossary (last updated July 8, 2020) and its homeowner page (last updated November 18, 2025) explain the zones like this:
- Special Flood Hazard Area (SFHA). The area expected to flood in a flood with a 1% chance of happening in any given year, often called the 100-year flood. FEMA notes that's a 26% chance of flooding over the life of a 30-year mortgage. Zones that start with A or V are in this high-risk area.
- Zone A. High risk, mapped with approximate methods, so no base flood elevation is shown.
- Zone AE. High risk, mapped with detailed methods, with base flood elevations shown.
- Zone A99. The City of Sacramento calls it an interim designation that is still high risk. More on Natomas below.
- Shaded Zone X. Moderate risk, between the 1% and the 0.2% (500-year) flood. Not part of the SFHA.
- Unshaded Zone X. Minimal risk, outside the 0.2% flood area.
A useful way to read it: A means a lender will likely require insurance, and X means it's your choice.
When does a lender require flood insurance?
FEMA's flood insurance page (last updated October 20, 2026) says homes in high-risk flood areas with mortgages from government-backed lenders are required to have flood insurance. Your lender will tell you whether your loan falls under that rule.
What that means for you:
- If the home is in a zone starting with A, plan on flood insurance as part of your monthly payment, often collected through your escrow or impound account.
- If you pay cash, no lender requires it. The risk is still there.
- If your lender requires coverage, keep the policy in force for as long as the loan requires it.
We ask for an insurance quote early in escrow, during your contingency period, so the full payment is known before you remove contingencies. Our guide to contingencies explains that timeline.
What is the difference between NFIP and private flood insurance?
The National Flood Insurance Program (NFIP) is run by FEMA. FEMA says its policies are sold through a network of more than 47 insurance companies plus NFIP Direct. FEMA's FloodSmart site for agents (checked October 22, 2026) lists the residential maximums as $250,000 for the building and $100,000 for contents.
Private flood insurance comes from insurance companies outside the NFIP. Some offer higher limits or different terms. If your lender requires flood insurance, a private policy has to meet the lender's standards, so check with the lender before you buy.
Questions to ask either kind of agent:
- What is the building limit and the contents limit?
- Is contents coverage at actual cash value or replacement cost?
- What is the deductible, and what is the waiting period?
- Can the policy be transferred to me if the seller already has one?
FEMA says new NFIP policies typically have a 30-day waiting period. There are exceptions, including coverage required by a lender when you get a loan. California's Department of Insurance can answer questions about insurers licensed in the state. For fire coverage, see our homeowners insurance and FAIR Plan guide.
What does it mean to live in Natomas?
The City of Sacramento's Natomas floodplain page (checked October 22, 2026) tells the story. After the Army Corps of Engineers re-evaluated the levees, FEMA remapped the Natomas Basin into Zone AE in December 2008. That required raising or flood-proofing new buildings, by up to 20 feet in some places, and stopped most building.
Since June 16, 2015, Natomas has had an A99 designation. The city calls A99 an interim designation that is still considered a high-risk flood zone, but one that allows construction with local conditions. The page says property owners in the Natomas Basin who have a federally backed mortgage will still need flood insurance because the levee improvements are not complete.
So if you're buying in Natomas with a loan, budget for flood insurance from day one. Ask your insurance agent what discounts apply in an A99 zone. SAFCA's flood events page lists Reclamation District 1000 as the levee maintenance contact for the Natomas Basin.
What about the Pocket, Greenhaven and other levee-protected neighborhoods?
The Pocket and Little Pocket sit along the Sacramento River behind the Sacramento River East Levee. SAFCA's flood events page lists that levee under the California Department of Water Resources, Maintenance Area 9. The county's levee-break scenario maps for American River South include the Pocket.
A home behind a levee may not be in a FEMA high-risk zone. Look up the exact address, because zones can change from one street to the next. If the home maps outside the high-risk area, flood insurance is optional. A levee lowers risk. It doesn't remove it. That's why many owners behind levees think about coverage even when no lender requires it.
Two habits help: look at the county's scenario maps for your area, and know your evacuation route. The county cautions that the routes on its maps may not be your way out in a real flood, so have a second plan.
Does a seller have to disclose a flood zone?
Yes. California's Natural Hazard Disclosure Statement, set out in Civil Code section 1103.2, asks whether the home is in a FEMA Special Flood Hazard Area and whether it is in an area of potential flooding from a dam failure. Most sellers order a report from a natural hazard disclosure company to fill it in.
Sellers should also share what they know firsthand. That includes past water in the home or the crawlspace, insurance claims for water, and drainage problems. Our seller disclosures guide walks through every form. This is general information, not legal advice. A real estate attorney can help with an unusual situation.
What should a buyer check before making an offer near a river?
- Look up the address on FEMA's Map Service Center and MyHazards.
- Ask for the seller's natural hazard report and disclosures.
- Ask the seller whether they carry flood insurance and what it costs.
- Get your own flood and homeowners quotes during your contingency period.
- Look at the county's levee-break scenario maps for the area.
- During the inspection, ask about grading, drainage and any signs of water in the crawlspace or garage.
Our guide to making an offer explains how to build these checks into your timeline.

Frequently Asked Questions
How do I find out if a house is in a flood zone?
Enter the address at FEMA's Flood Map Service Center (msc.fema.gov) and open the map to see its FIRMette. Cal OES's MyHazards tool shows other natural hazards too. Your lender will also order a flood zone determination.
Is flood insurance required in Sacramento?
It's required when the home is in a FEMA high-risk zone and you have a mortgage from a government-backed lender, according to FEMA's flood insurance page (updated October 20, 2026). Outside high-risk zones it's optional.
What is Zone A99 in Natomas?
The City of Sacramento says Natomas has had an A99 designation since June 16, 2015. A99 is an interim high-risk zone that allows building with local conditions. Owners with a federally backed mortgage still need flood insurance.
What is the difference between Zone AE and Zone X?
Zone AE is high risk, inside the 1% annual chance floodplain, with base flood elevations shown. Zone X is moderate (shaded) or minimal (unshaded) risk outside that floodplain, per FEMA's flood zones glossary.
How much flood coverage can I get through the NFIP?
FEMA's FloodSmart agent site lists residential maximums of $250,000 for the building and $100,000 for contents. Private flood policies may offer other limits.
Is there a waiting period for flood insurance?
FEMA says NFIP policies typically take effect after 30 days. Exceptions include coverage a lender requires when you get a loan, and coverage tied to a flood map change.
If my home is behind a levee, do I need flood insurance?
Not if it maps outside FEMA's high-risk zone, unless your lender requires it. A levee lowers risk but doesn't remove it, so many owners behind levees consider optional coverage.
