How Lincoln County floods

Flash flooding dominates the flood character of Lincoln County, accounting for 59 of the 68 recorded flood events over the last 30 years, alongside 7 general flood events (resulting in 1 death) and 2 tropical storms. Heavy rainfall events regularly threaten infrastructure, as demonstrated on February 23, 2022, when excessive rainfall brought 4 to 5.5 inches of rain to southern middle Tennessee, causing several road closures in Lincoln County and prompting school closures.

Federal insurance claims data shows that property damage occurs in both high-risk and lower-risk zones. Properties in high-risk Zone A account for the highest claim volume with 36 claims averaging an $12,828 payout and an average recorded water depth of 3 inches. Meanwhile, properties in Zone X recorded 10 claims with an average payout of $24,707 and an average recorded water depth of 6 inches, while Zone X unshaded recorded 1 claim with an average payout of $997 and an average water depth of 3 inches. Zone unknown recorded 2 claims averaging a $96 payout with an average water depth of 0 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located within designated Zone A due to the high frequency of flood claims, as well as structures in Zone X where average claim payouts and recorded water depths have been higher during flood events.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Flood insurance in Lincoln County

If a building in Lincoln County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
