Flood Zones and Flood Insurance in Manchester and Coffee County TN

Before you buy a home in Manchester or anywhere in Coffee County, it pays to know two things early: what flood zone the address is in, and what flood insurance would cost. The answers can affect your loan, your monthly budget and how you plan any future building. This guide explains how to look up a flood zone, what the zone letters mean and how flood insurance works, using FEMA and Tennessee sources.

This is general information, not insurance, lending or legal advice. Your lender, a licensed insurance agent and the local floodplain administrator have the final word for a specific property.

How to look up the flood zone for an address

FEMA calls its Flood Map Service Center the official public source for flood hazard information produced for the National Flood Insurance Program, or NFIP. Anyone can view and download flood maps there. FEMA describes the steps this way:

• Visit the Map Service Center
• Type in the street address
• Click the dynamic map button to view your FIRMette from the official Flood Insurance Rate Map, or FIRM

The Tennessee Emergency Management Agency also points to the Tennessee Property Viewer, which it says covers 85 of the state's 95 counties. You choose a county, search by address, owner, parcel or subdivision, select the property and turn on the FEMA flood map layer.

Maps change. FEMA says flood maps are continually updated and that information you download or print may later be superseded by new maps. TEMA notes that its Flood Map Changes Viewer shows current flood hazard data along with preliminary map information. If a map update is in the works for an area you are considering, ask how it could affect the property.

What the flood zone letters mean

FEMA defines a Special Flood Hazard Area, or SFHA, as the area that will be flooded by the flood event having a one percent chance of being equaled or exceeded in any given year. That event is also called the base flood or the 100 year flood. Here is how FEMA describes the zones you are most likely to see:

• Zone A. Areas with a one percent annual chance of flooding and a 26 percent chance of flooding over the life of a 30 year mortgage. Detailed studies were not done, so no flood depths or base flood elevations are shown.
• Zone AE. Also part of the SFHA. The City of Manchester floodplain ordinance treats AE Zones as areas where base flood elevation data is available.
• Zone X (shaded), also shown as Zone B. Moderate flood hazard areas between the limits of the base flood and the 0.2 percent annual chance flood, also called the 500 year flood.
• Zone X (unshaded), also shown as Zone C. Areas of minimal flood hazard, outside the SFHA and higher than the 0.2 percent annual chance flood.

FEMA says high risk flood zones are the areas beginning with the letters A or V on its maps. FEMA notes that Zones V and VE are used for coastal areas.

When a lender requires flood insurance

FEMA explains that mortgage lenders use flood maps to decide whether to require flood insurance as a condition of a loan. Lenders require owners inside an SFHA to buy flood insurance if they have a government backed loan on the building. This is called the mandatory purchase requirement. FEMA adds that some lenders may require flood insurance outside an SFHA too, as part of their own risk management.

FEMA advises learning the lender's insurance requirement before you buy, to prevent delays at closing. Ask your lender early whether the address will need flood coverage.

Flood insurance basics

FloodSmart, the NFIP consumer site, says most homeowners and renters insurance does not cover flood damage. Key points from FloodSmart and FEMA:

• Any homeowner in a community that participates in the NFIP is eligible for an NFIP policy, including condominium and townhouse owners.
• Building coverage goes up to $250,000 and contents coverage up to $100,000. They are usually purchased separately and have separate deductibles.
• Building coverage includes items such as electrical and plumbing systems, furnaces and water heaters, foundation walls, detached garages, fuel tanks and well water tanks and pumps.
• Property outside the insured building, such as landscaping, septic systems, decks and patios, fences and swimming pools, is not covered. Neither is personal property kept in basements.
• An NFIP policy lasts one year.

A home does not have to be near water to flood. FEMA says floods can come from storms, drainage system backups, broken water mains and changes to land from new construction, and that from 2014 to 2024 almost one third of NFIP flood insurance claims came from areas outside current high risk flood areas. Flood insurance is available to property owners outside high risk areas as well.

The 30 day waiting period

FloodSmart says a new flood policy generally takes effect 30 days after purchase, with exceptions. The ones that matter most to buyers:

• Buying with a mortgage. There is no wait if you buy flood insurance while making, increasing, extending or renewing a mortgage.
• Taking over the seller's policy. FEMA says a seller can transfer their policy to the new owner, whether or not there is a mortgage involved.
• Newly mapped high risk areas. There is a one day wait if your property was newly placed in a high risk flood zone and you buy within the time allowed after the map update.

If you are paying cash and want coverage from day one, start the insurance quote early in your inspection period so the 30 day clock does not catch you off guard.

How flood insurance is priced

FEMA fully implemented its current NFIP pricing approach, known as Risk Rating 2.0, on April 1, 2023. FEMA says rates now reflect a property's own flood risk, using factors such as flood frequency, flood types like river overflow and heavy rainfall, distance to a water source, the building's elevation and the cost to rebuild. FloodSmart says NFIP insurers all use the same pricing approach, so each one offers the same rate for the same policy.

FEMA also says existing statutory limits keep most rates from rising more than 18 percent per year, and that a policyholder can pass a premium discount to a new owner by assigning the policy when the property sells. Because every home is priced on its own, there is no typical premium to quote here. Ask a licensed insurance agent for a quote on the specific address, or use the NFIP quoting tool linked from FloodSmart.

Elevation Certificates

FEMA describes an Elevation Certificate as an optional NFIP tool that documents a building's elevation and can potentially lower a flood insurance premium. To find out whether a property already has one, FEMA suggests asking the local building permit office, the local planning and zoning office, the previous owner or a flood insurance agent. If none exists, a licensed land surveyor, engineer or architect can prepare one. Ask the seller early in the process.

If you think the map is wrong

If you believe a property was shown in an SFHA by mistake, FEMA lets you apply for a formal determination called a Letter of Map Change. A Letter of Map Amendment covers an existing structure or parcel on naturally high ground that would not be flooded by the base flood, and a Letter of Map Revision Based on Fill covers one raised by earthen fill. FEMA says that if the request is granted, the owner may send the determination to the lender and ask that the federal flood insurance requirement be removed. Details are on FEMA's Change Your Flood Zone Designation page. A land surveyor or engineer can tell you whether a request makes sense.

Building, adding on or repairing in a flood zone

Floodplain rules are enforced locally. Inside Manchester city limits, the City of Manchester Municipal Floodplain Zoning Ordinance (Title 14, Chapter 10 of the city code) applies. It says the city wants to stay eligible for the NFIP and that areas of the city are subject to periodic flooding. Among its rules:

• A development permit is required before any development in a special flood hazard area. Development is defined broadly and includes buildings, filling, grading, paving and excavating.
• The city codes and safety director is the administrator of the ordinance.
• In AE Zones, new construction and substantial improvement of a home must have the lowest floor, including any basement, at least one foot above the base flood elevation.
• A substantial improvement is work over a five year period whose total cost equals or exceeds 50 percent of the structure's market value.

The ordinance also says it does not imply that land outside special flood hazard areas will be free from flooding. Outside city limits, TEMA says to contact the county floodplain administrator, and its Statewide Floodplain Administrator Directory lists contacts for participating communities. For zoning and building permits in rural Coffee County, start with the Coffee County Codes Compliance office at 1329 McArthur Street in Manchester. Planning a shop, addition or fill work? Call before you buy, not after.

For sellers: flood records and disclosure

Under TCA 66 5 202, a Tennessee seller gives the buyer either a disclosure statement covering the condition of the property and known material defects, or a disclaimer statement if the buyer waives the disclosure. If you know about water getting into the home or other flooding problems, talk with a Tennessee attorney about how that belongs on your disclosure. My seller disclosure guide explains the statute.

Buyers will ask about flood zones, so gather what you have before you list: any Elevation Certificate, your current flood policy if you have one (FEMA says it can be transferred to the buyer), and any FEMA Letter of Map Change for the property.

A buyer flood checklist

• Look up the address on the FEMA Flood Map Service Center and save the FIRMette
