If you're looking near Oak Vale, save the parcel ID before closing the panel; every records desk in the county asks for it first.
When a parcel crosses a boundary
Jefferson Davis County touches Covington County, Lamar County, Lawrence County, Marion County, and Simpson County, and each of those keeps its own parcel map.

Taking the map into the field

A short flood checklist

Zones on the Jefferson Davis County flood zone map
An AE label comes with a base flood elevation, and an unnumbered A zone has none; builders around US Route 84 design to it. If the land is near US Route 84, a low-risk label isn't a guarantee: FEMA notes that floods happen outside mapped zones too.
Low spots and local drainage
Low-lying fields near Bassfield may not have detailed mapping, so ask neighbors about past flooding. Wet ground around US Route 84 is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
The paper trail behind a parcel
When the details count, request the recorded deed through the Chancery Clerk; the parcel map near US Route 84 only summarizes it. If the land is near US Route 84, bring the book and page shown in the record panel to skip a name search.
Limits of the parcel data
Tax maps are drawn for assessment, not measured on the ground, so a fence near US Route 84 can sit some distance off the line on screen. If you're looking near Carson, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so check the MARIS Mississippi Statewide Parcels map viewer too to confirm you have the right parcel near US Route 84.
