Ahead of any purchase around Red Lick, check the Jefferson County flood zone map: FEMA's zone label affects insurance, permits and resale. What this county guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the county ArcGIS parcel map around McBride.
Checking the Jefferson County flood zone map step by step
Flood zones come from FEMA's Flood Map Service Center: type an address near Harriston, then open the map view for that panel. Rural land near Homochitto National Forest with no street number is still easy to locate: pan from the closest town and click the spot.
The free map to start with
Property in and around Fayette appear on the Jefferson County ArcGIS parcel map, which opens without registering. Out toward Red Lick, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. With a lot near Homochitto National Forest, save the parcel ID before closing the panel; each office in the county will want it.
How land is described here
Mississippi is laid out under the Public Land Survey System, so deeds around Fayette reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Homochitto National Forest can be irregular. Write down the legal description for the tract near McBride for any title or survey request.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Lorman, so load it before you lose signal. A saved image of the lot near McBride and its lines keeps working without signal.
Who handles what
Recorded documents for a parcel near Harriston come from the Chancery Clerk, often with an online index. Questions about what you can build around Harriston need the planning or permitting office, depending on whether the land is inside town limits.
Land on the county line
Jefferson County touches Tensas Parish, LA, Adams County, Claiborne County, Copiah County, and Franklin County; every one of them runs a separate parcel map. A tract near the line by Red Lick can be split across two assessors' files, so open the neighboring map as well. If the land is near Cannonsburg, our state page links every neighboring county map across Mississippi.
Beyond the mapped zones
Low-lying fields near Cannonsburg may not have detailed mapping, so look for water marks and debris lines. Marshy spots near McBride can limit building too; check the National Wetlands Inventory mapper for a first look.
Getting your bearings
Fayette is the county seat, home to the main records offices. Other places on the map include Cannonsburg, Harriston, Lorman, and McBride, each with its own cluster of lots. Roughly 6,941 people call Jefferson County home (Census estimate, 2023) on about 520 square miles. The county was formed in 1799, so old deeds can run back a long way, especially near Homochitto National Forest. Features like Homochitto National Forest are easy to spot when you zoom out.
Deeds, plats and who keeps them
For anything that matters, request the recorded deed through the Chancery Clerk; the parcel line is a drawing of it, which applies near Cannonsburg as much as anywhere. If you're looking near Harriston, use the instrument number from the tax record and the lookup takes minutes.
A word on accuracy
Parcel lines are drawn for taxes, not measured on the ground, so a tree line near Cannonsburg can sit some distance off the line on screen. Records update in batches, so a recent sale near Homochitto National Forest might lag behind.
Zones on the Jefferson County flood zone map
An AE label carries a published BFE, while plain Zone A does not; builders around Red Lick design to it. For a tract near Cannonsburg, minimal risk is not no risk: according to FEMA, floods happen outside mapped zones too.
Use the county map alongside FEMA
Where a floodplain cuts across acreage near McBride, the location of the house or building pad decides a lot.
What a flood zone means for a buyer
For a tract near McBride, ask for an Elevation Certificate: it compares the building to the BFE. New construction in a floodplain near McBride often needs a floodplain permit; ask the local floodplain administrator before you plan.
A short flood checklist
Request about past flood claims for the house near Red Lick; an insurance quote early keeps the budget honest.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
