This guide is for the person holding one address: a seller preparing a disclosure, or a buyer deciding whether to write an offer. It deliberately does not tell you which parts of Nashville flood. No honest source can answer that for your address from a neighborhood name, and the map itself is only the first reading.

What May 2010 established

On May 1 and 2, 2010, the National Weather Service office in Nashville recorded 13.57 inches of rain at Nashville International Airport, a two-day record that shattered the previous mark of 6.68 inches set in September 1979. May 2 alone brought 7.25 inches, which still stands as the all-time 24-hour maximum in NWS Nashville’s climate records.

The Cumberland River at Nashville crested at 52.55 feet on May 3, 2010, against a flood stage of 40 feet. That was the highest level since dams began regulating the river, well above the 47.6 feet recorded on March 15, 1975, but short of the all-time record of 56.20 feet set in 1927, before dam control. NWS notes speculation that without river control the 2010 level would have come close to 56 feet. It reports that the storm killed 18 people in Middle Tennessee and at least 27 across Tennessee and Kentucky, that damage estimates vary widely but totaled into the billions of dollars, and that the event prompted a Presidential Disaster Declaration.

The river was not the whole story

For a single address, the more useful lesson of 2010 is that the river gauge did not describe the whole event. NWS gauge records show Mill Creek setting records at two gauges, Richland Creek cresting almost 5 feet above its 1979 level, Browns Creek cresting 5 feet above its 1993 record, and the Harpeth River setting records at three locations.

Eleven years later, NWS described the flash flood of March 27 and 28, 2021 as the worst in Middle Tennessee since May 2010. A Flash Flood Emergency covered southeastern Davidson, western Wilson and northern Williamson counties, which received 7 to 9 inches of rain. Sevenmile Creek reached its highest level on record, and more than 500 homes and businesses flooded.

Neither event is a statement about any particular street. Both are reasons to look up the one address you care about rather than reason from a neighborhood’s reputation or what a neighbor remembers.

The dams upstream do not change that. The U.S. Army Corps of Engineers built Dale Hollow, Center Hill and Wolf Creek dams under the Flood Control Act of 1938 and completed them for flood control between 1943 and 1950, and the 1927 record predates that control. If the speculation NWS reports is right, river control kept the 2010 crest a few feet lower than it would otherwise have been. It did not keep the river below flood stage.

What a FEMA Special Flood Hazard Area is

FEMA defines the Special Flood Hazard Area as the land inundated by the 1-percent-annual-chance flood, also called the base flood or the 100-year flood. The last name misleads people. A 1-percent annual chance applies every year, and Metro Water Services translates it into terms a homeowner can use: a structure located within the Special Flood Hazard Area has a 26 percent chance of flooding during the life of a standard 30-year mortgage.

Every location on a Flood Insurance Rate Map, or FIRM, carries a zone designation. FEMA’s glossary groups them like this:

Two more terms matter in Nashville. The base flood elevation is the elevation of that 1-percent-annual-chance flood at a given location, and it is the line Metro measures its building rules against. The floodway is a regulated portion of the floodplain in which Metro prohibits development, with few exceptions.

How to look up one address, step by step

Work through these in order. Each step answers a narrower question than the one before it.

Step 1: Start at FEMA’s Flood Map Service Center

Go to msc.fema.gov, FEMA’s Flood Map Service Center, which FEMA describes as the official public source for flood hazard information supporting the National Flood Insurance Program. Enter the street address, a place name or coordinates to bring up the effective Flood Insurance Rate Map for that location. FEMA lists the Metropolitan Government of Nashville and Davidson County as NFIP community 470040. Belle Meade, Berry Hill, Forest Hills, Goodlettsville, Oak Hill and Ridgetop are listed as separate NFIP communities, so for an address inside one of those cities, confirm the flood map and the floodplain rules with that city, not only with Metro.

Step 2: Read the zone at the building, then across the parcel

Note the zone designation where the structure sits, then look across the whole parcel. A zone boundary or a floodway line can run through a lot, leaving the house in one designation and the rear yard or the driveway in another. Write down the zone letters exactly as the map shows them, and the FIRM panel number.

Step 3: Compare Metro’s Flood Information Risk and Storm Tool

Metro Water Services publishes its own Flood Information Risk and Storm Tool, which Metro describes as showing regulated floodplains and providing comprehensive flood-related data. Compare it with the FEMA result. If the two appear to differ, or the building sits near a boundary on either, carry that exact question into step 4.

Step 4: Ask Metro Development Services for the record

Metro Water Services states that its Development Services Division, at 615-862-7225, will provide on request the FIRM zone, the panel number, the base flood elevation, whether the property is located in a floodway, and copies of elevation certificates. Ask specifically whether an elevation certificate is on file for the building. The map describes an area. This call describes the parcel.

Step 5: Check the parcel record

Zoning, overlay districts, lot size and flood mapping vary lot by lot. Look the parcel itself up in the Nashville Parcel Viewer rather than relying on any description of the district around it. A statement about an area is not a statement about an address.

Step 6: Read the seller’s disclosure against the map

Tennessee’s statutory disclosure form asks the seller about flooding, drainage and grading problems, about any requirement that flood insurance be maintained on the property, and about flood damage. Read those answers next to what FEMA and Metro returned. A clean map and a disclosed drainage problem are not a contradiction; they are different kinds of information, and you want both.

Step 7: Get a flood insurance quote before you are committed

Request a quote for the specific building during due diligence, not after closing. Metro Water Services notes a 30-day waiting period before NFIP coverage goes into effect. FEMA’s FloodSmart site lists exceptions, including no wait when the policy is bought while making, increasing, extending or renewing a mortgage, so ask the insurance agent how the timing works for your contract and your loan.

How Metro regulates building in the floodplain

Metro Water Services regulates development in Special Flood Hazard Areas through its Stormwater Management Manual. The regulations sit in Volume 1, with Chapter 5 covering floodplain requirements, and the current chapter PDFs are dated 2026. All development in a Special Flood Hazard Area requires local permits, and any land-disturbing activity over 10,000 square feet in Metro Nashville-Davidson County requires a grading permit.

Why substantial improvement matters to a seller

The lowest-floor rule reaches existing houses, because it applies to substantial improvement of a residential structure as well as to new construction. For an owner planning a large renovation or an addition inside the Special Flood Hazard Area, that can change the economics of the project entirely, and for a seller it changes what the next owner can do with the house. Substantial improvement is a defined term in Metro’s regulations. Confirm with Metro how it applies to the specific building before you scope, price or promise a renovation.

The same rules shape what a builder can do with a lot that lies partly in the floodplain: the four-foot elevation, the cut-for-fill requirement and the floodway prohibition sit alongside zoning. The companion guide, What Is an HPR in Nashville? Tall and Skinny Homes Explained, covers the zoning and ownership side of infill; the floodplain rules apply in addition, parcel by parcel.

Sinkholes

The other ground-and-water question in Tennessee is sinkholes. Metro’s manual, Volume 1, Section 6.9, defines a sinkhole as a depression occurring naturally in a karst area with no surface outflow, and requires stormwater systems that discharge to one to be engineered for the 100-year storm assuming plugged conditions, with a geologic investigation. The U.S. Geological Survey lists Tennessee among seven states where sinkhole damage tends to be greatest.

What a Tennessee seller must disclose about flooding

Tennessee’s Residential Property Disclosure Act, Tenn. Code Ann. 66-5-201 and following, requires the owner of residential property to furnish the purchaser one of two documents: a residential property disclosure statement covering the condition of the property, including any material defects known to the owner, or, only where the purchaser waives that disclosure, a disclaimer statement that the owner makes no representations as to condition and that the purchaser takes the property as is. The disclosure is the owner’s representation, not the licensee’s, and the owner is not required to undertake an independent investigation or inspection to make it.

The statutory form addresses water directly. The disclosure form set out in Tenn. Code Ann. 66-5-210 asks about flooding, drainage or grading problems on the property, about any requirement that flood insurance be maintained, about property or structural damage from fire, earthquake, floods or landslides, and about settling, slippage, sliding or other soil issues.

Each question turns on what the seller is aware of. A past flood claim, a water remediation invoice, regrading done to move water away from the foundation, or a lender’s flood insurance requirement are the kinds of records worth gathering before you complete the form, and an attorney is the right person to ask how a specific past event should be described. The wider sale process, including costs and timing, is covered in Selling a Home in Nashville: The Complete 2026 Guide to Pricing, Costs, and Timing.

When no disclosure statement arrives

Twelve categories of transfer are excluded from the Act under 66-5-209. Among them are transfers by court order or foreclosure sale, transfers by a fiduciary administering an estate, the first sale of a dwelling where the builder offers a written warranty, property sold at public auction, and transfers where the owner has not resided on the property at any time within three years before the transfer. In those transactions a buyer may receive no condition statement at all, and the lookup above becomes the buyer’s own work.

The builder exclusion matters for new construction. A buyer of a newly built home near a mapped floodplain should ask the builder directly for the elevation information and permits behind the house; New Construction in Middle Tennessee: Builder Contracts, Warranties and Who the On-Site Agent Represents covers builder contracts and warranties. Vacant land sits outside the Act as well: Tennessee REALTORS removed its vacant-land disclosure report in 2019 because disclosure reports are not required by law for vacant land.

Licensees carry a separate duty. Under Tenn. Code Ann. 62-13-403, a licensee must disclose to each party to the transaction any adverse facts of which the licensee has actual notice or knowledge, while under 62-13-405 licensees are not obligated to discover or disclose latent defects. Neither replaces the seller’s own disclosure or the buyer’s own lookup.

Flood insurance, as far as the public record goes

Metro Water Services states that flooding is not covered by a standard homeowner’s insurance policy, that flood insurance is available to homeowners, condo owners, commercial owners and all renters, and that there is a 30-day waiting period before coverage goes into effect. FEMA’s FloodSmart site lists exceptions to that wait, including a policy bought while making, increasing, extending or renewing a mortgage.

FEMA’s Community Rating System is a voluntary program in which NFIP premiums are discounted 5 percent per class, from Class 9 at 5 percent to Class 1 at 45 percent, with Class 10 meaning a community does not participate. FEMA’s list effective April 1, 2026 shows the Metropolitan Government of Nashville and Davidson County, NFIP community 470040, at Class 8, a 10 percent discount that applies to NFIP policies inside and outside the Special Flood Hazard Area. The class belongs to that community; Davidson County’s separately incorporated cities are separate NFIP communities.

This guide quotes no premium figure. The number that matters is a quote for the specific building, requested before you are committed and read alongside the seller’s answer on whether flood insurance must be maintained on the property.

If you are selling: putting it to work

• Pull the FEMA result for your address, and ask Metro Development Services for the zone, base flood elevation, floodway status and any elevation certificate on file before you list, so the answers are in hand when a buyer asks.
• Gather the records behind every water-related answer on the disclosure form.
• State the zone designation and its source. Do not turn a designation into a promise about the house.
• Before pre-sale work on a house in the Special Flood Hazard Area, confirm with Metro how the substantial improvement rules apply.
