Mandeville
Local flood insurance, built for St. Tammany Parish.
A lakefront that floods without a hurricane
Mandeville is the rare market where flooding does not require a named storm. St. Tammany Parish has logged events where strong onshore flow alone pushed tides roughly two feet above normal and flooded the Mandeville lakefront at high tide. That is a nuisance-flood profile the inland Northshore simply does not have.
Ida reversed the usual pattern
Hurricane Ida hit western St. Tammany harder than the east — the opposite of Katrina. The National Hurricane Center surveyed high-water marks of 6 to 9 feet above ground in western St. Tammany versus 4 to 7 feet in the east, with a gauge reading of 7.1 feet above mean higher high water at Mandeville. Which side of the parish you are on changes storm to storm.
"Higher ground" is only half true here
The Northshore is genuinely higher than metro New Orleans in its northern reaches, but that gradient runs downhill toward the lake. Mandeville lakefront ground sits only single-digit feet above sea level, and parish modelling puts worst-case flood depths for the lakefront communities near 18 feet. Elevation relative to base flood elevation is what actually drives your rate.
