Look up the Marshall County flood zone map step by step
FEMA's official flood maps for Marshall County are free at the FEMA Flood Map Service Center. Search returns the effective FIRM panel for the spot in Marshall County, plus any pending changes FEMA has posted. On acreage outside Byhalia, the National Flood Hazard Layer viewer is easier to use and reports the zone wherever you click near Byhalia. Next, the Marshall County ArcGIS parcel map confirms which Marshall County parcel you're looking at. If the Marshall County viewer has a floodplain layer, treat it as a convenience copy and confirm on FEMA's map.
Opening the Marshall County parcel viewer
Marshall County publishes its parcels on the Marshall County ArcGIS parcel map, which runs on an Esri ArcGIS web map, free to use for a lot in Byhalia or a parcel near Potts Camp. Most people locate their Marshall County tract fastest by searching an address in Potts Camp, then clicking the outline. For a backup route to the map covering Potts Camp, our Marshall County directory entry keeps the link current.
Zone A, AE and X in plain English
On the FIRM covering Marshall County, zones that start with A or V are Special Flood Hazard Areas, meaning FEMA estimates a 1-percent annual chance of flooding. Where a Marshall County tract lists Zone AE, there's a base flood elevation to compare a building against; in Zone A there isn't one. If a Marshall County parcel lists shaded Zone X, it falls between the base flood and the 500-year flood. Clear, unshaded X near Byhalia is outside the 500-year floodplain.
Low ground and small streams around Byhalia
A low spot on a Marshall County tract outside any mapped zone, which is why it's worth walking the ground after a heavy rain.
Questions to ask before buying in Marshall County
For a house near Potts Camp, ask the seller for any elevation certificate on file and the current flood insurance declarations page. Then call an insurance agent who writes policies around Holly Springs and get a quote using the zone and the county parcel address.
Reading the fine print on a Marshall County panel
The FIRM panel for Marshall County carries an effective date; if it's old, ask the county floodplain office if new maps for land near Byhalia are in progress. If a parcel near Byhalia lists a hatched floodway, expect tight limits on fill and new structures from the county floodplain office.
What a flood zone means for a Marshall County buyer
Here's why the zone matters at a closing in Byhalia. If a house near Holly Springs sits in a Special Flood Hazard Area and is financed by a regulated or federally insured lender, a flood policy becomes a loan condition under the Flood Disaster Protection Act, wherever the community joins the NFIP. For a Marshall County home in shaded or unshaded X, coverage is optional, although a lender in Mississippi can still ask for it. If a building near Holly Springs sits above the flood line, a Letter of Map Amendment request is the formal route, supported by elevation data from a professional surveyor. Placing fill on low ground near Byhalia has to meet local floodplain rules, so call the county or the town office in Byhalia before work starts.
