About Memphis Flood Zone Map Explained: AE, X & A Zones (2026)
Find your Memphis, TN flood zone on the FEMA map. AE vs Zone X explained, Mississippi & Wolf River risk, NFIP cost, and how an independent agent helps.
What flood zones are — and why Memphis has them
A FEMA flood zone estimates a property's flood risk over time. Memphis sits at the edge of the Mississippi River, one of the most powerful river systems in North America, and is drained by the Wolf River, Nonconnah Creek, and the Loosahatchie River. Backwater flooding from the Mississippi can raise water levels in areas far from the main channel, and intense rain produces urban flash flooding. Homeowners insurance never covers rising water, so your flood zone is a key part of protecting your home.
How to look up your Memphis flood zone
Begin at FEMA's Flood Map Service Center (msc.fema.gov) and enter your Memphis address to see your flood zone and FIRM panel. The City of Memphis and Shelby County floodplain offices can confirm designations and explain how levee and drainage systems factor into your map.
Memphis flood zones explained
Memphis is inland, so its high-risk areas use the river/creek (A-series) zones rather than coastal V zones.
What do AE, A, AO, AH, and X mean?
The table below covers the designations Memphis homeowners are most likely to encounter.
| Zone | Risk level | What it means |
|---|---|---|
| AE | High | 1% annual flood chance with FEMA base flood elevations; insurance mandatory with a federal mortgage |
| A | High | 1% annual chance, no detailed elevations established |
| AO / AH | High | Shallow sheet-flow or ponding flooding (1–3 ft) |
| X (shaded) | Moderate | 0.2% annual chance (the "500-year" floodplain) |
| X (unshaded) | Minimal | Outside mapped floodplains; coverage optional but recommended |
Do I need flood insurance in Memphis?
If your home is in Zone AE or A with a federally backed mortgage, flood insurance is required. In a Zone X area it is optional — but FEMA reports roughly a quarter of NFIP claims come from outside high-risk zones, and the Mississippi's backwater flooding can reach properties that feel a safe distance from the river.

Average flood insurance cost in Memphis
There is no single Memphis flood premium — under FEMA's Risk Rating 2.0, each policy is priced from your property's distance to water, elevation, foundation type, and replacement cost. As a benchmark, the average NFIP policy in Tennessee runs about $1,220/year (source: NerdWallet (FEMA NFIP data)). Homes in a high-risk AE or VE zone typically pay more than that average; homes in a Zone X (Preferred Risk) area often pay well under it. Private flood carriers can be more competitive for some Memphis homes, so it is worth comparing NFIP and private side by side.
Roughly a quarter of all NFIP claims nationally come from properties outside mapped high-risk zones, which is why coverage is worth considering even in a Zone X area (source: FEMA / FloodSmart.gov).
NFIP vs. private flood insurance in Memphis
| Feature | NFIP (federal) | Private flood |
|---|---|---|

| Contents coverage limit | Up to $100,000 | Higher limits available |
| Additional living expenses | Not covered | Often included |
| Waiting period | Typically 30 days | Often shorter (varies) |
| Pricing basis | FEMA Risk Rating 2.0 | Carrier's own flood model |
NFIP limits per FEMA; private flood terms vary by carrier. TCDS is an independent agency and can compare NFIP and private flood options for your Memphis home in one conversation.

Frequently Asked Questions
How do I find my Memphis flood zone?
Use FEMA's Flood Map Service Center at msc.fema.gov and enter your Memphis address to see whether you are in Zone AE or A (high-risk), Zone X shaded (moderate), or Zone X unshaded (minimal). The City of Memphis and Shelby County floodplain offices can confirm your zone.
Which areas of Memphis flood the most?
Memphis flood risk concentrates along the Mississippi River, the Wolf River, Nonconnah Creek, and the Loosahatchie River, plus low-lying neighborhoods where intense rain overwhelms drainage. Backwater flooding from the Mississippi can affect areas well inland.
Do I need flood insurance in Memphis if I'm not in a flood zone?
It is worth considering. Standard homeowners insurance never covers flood damage, and FEMA reports roughly a quarter of NFIP claims come from outside high-risk zones. Lenders require flood insurance for federally backed mortgages on homes in Zone AE or A.
How much does flood insurance cost in Memphis?
FEMA's Risk Rating 2.0 prices each policy from distance to water, elevation, and replacement cost, so there is no single Memphis figure. The Tennessee NFIP average is about $1,220/year (NerdWallet, FEMA NFIP data); Zone X homes often pay less and AE-zone homes more. Private flood carriers can also be competitive.
What is the difference between Zone AE and Zone X in Memphis?
Zone AE is a high-risk Special Flood Hazard Area with a 1% annual flood chance and FEMA base flood elevations; insurance is mandatory with a federally backed mortgage. Zone X shaded is moderate risk (0.2% annual chance) and Zone X unshaded is minimal risk where coverage is optional but recommended.
