Common questions about flooding in St. Tammany Parish

Has St. Tammany Parish flooded recently?
Yes — the most recent flood loss with an insurance claim on file was on 2026-06-30, and claims were filed in 10 of the last 10 years (3,456 claims from 2017 to 2026). FEMA’s data runs to 2026-09-07, so the newest events may not appear yet.
Do I need flood insurance in a low-risk zone here?
Lenders generally require it only in high-risk A and V zones. But 28% of St. Tammany Parish’s claims came from moderate- and low-risk zones. Whether to buy coverage is your call — see flood zones explained and check your address on the FEMA Flood Map Service Center.
Can I see whether a specific house has flooded?
Not here. FEMA removes addresses before publishing, so these figures describe areas, never a property. Our guide how to check if a house has flooded lists the questions and records that can tell you about a specific home.
Why might the real number of floods be higher?
Only buildings with National Flood Insurance can file these claims, and most homes are not insured for flood. More on what the counts mean in understanding NFIP claims data.

About these numbers

Figures are aggregated from FEMA’s OpenFEMA NFIP Redacted Claims dataset (county FIPS 22103, data as of 2026-09-07). They cover only properties that carried National Flood Insurance — most homes do not, and private flood policies are not included — so real flood damage is larger than these counts show. Dollar amounts are as paid, in nominal dollars. Flood zone is the zone used to rate the policy at the time, which may differ from today’s map. FEMA states this dataset is not an official federal report. Use it for background, not for a purchase, insurance or legal decision; for a specific property ask the seller for its flood disclosure or the owner’s NFIP loss history.
