The Washington County flood zone map question tends to arrive at a bad moment: a lender's letter, an insurance quote, or a permit counter in Leland. For any tract in Washington County, Mississippi, the answer affects insurance, permits and resale.
Below are the FEMA links, a plain reading of the zone labels, notes on where water shapes land around Leland, and short answers to common questions.
Where to see the official Washington County flood zone map
The authoritative source for a Washington County flood zone map is FEMA, so begin at the FEMA Flood Map Service Center. Download the FIRM panel FEMA lists as effective for that part of Washington County. On acreage outside Greenville, try FEMA's National Flood Hazard Layer viewer; zoom to the parcel near Leland and click. Switch to the MARIS Mississippi Statewide Parcels map viewer and track down the same parcel near Leland. The Washington County record gives the parcel ID and legal description that an insurer or lender near Greenville may ask for.

High, moderate and minimal risk in Washington County
For a lot in Greenville, the label matters more than the color: A and V zones are Special Flood Hazard Areas, meaning FEMA estimates a 1-percent annual chance of flooding. Zone AE near Leland means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. If a Washington County parcel displays shaded Zone X, it is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded Zone X near Leland is minimal risk.
Low ground and small streams around Greenville
Small streams and ditches near Greenville may not be studied in detail, which is why it's worth walking the ground after a heavy rain.
Seller questions about flood history
For a house near Leland, ask the seller for any elevation certificate on file and the current flood insurance declarations page. Quotes for land near Stoneville depend on the zone and the building's elevation, so bring both to the agent.
Floodways and restudies near Hollandale
Look at the effective date printed on the county panel, since a new study can redraw zones around Leland. If a parcel near Hollandale displays a hatched floodway, expect tight limits on fill and new structures from the county floodplain office.
Flood insurance and building rules in Washington County
The zone displays up again when a loan on a house near Leland is underwritten. When a Washington County home falls inside an A or V zone and carries a federally backed mortgage, the lender must require flood coverage under the Flood Disaster Protection Act, wherever the community joins the NFIP. For a Washington County home in shaded or unshaded X, insurance is a choice, not a mandate, although a lender in Mississippi can still ask for it. When a Washington County homesite is on a rise inside a mapped zone, a Letter of Map Amendment request is the formal route, most commonly backed by an elevation certificate from a surveyor who works in Washington County. Adding on to a house near Leland inside the zone commonly requires a permit and an elevation check, and the building office serving Leland explains the steps.
Quick answers for Washington County
Is my Hollandale address in a flood zone?
Look it up at FEMA's Flood Map Service Center, then match the parcel lines in the MARIS Mississippi Statewide Parcels map viewer; for land near Greenville, a zone starting with A or V is high risk.
My lot in Hollandale displays Zone AE. What does that mean?
Yes, a parcel near Greenville in Zone AE is high risk: a 1-percent-annual-chance floodplain where FEMA lists a base flood elevation.
Is flood insurance required for a Zone X lot in Hollandale?
FEMA does not require it for a Zone X lot in Hollandale, but coverage is available and some lenders ask for it.
Does a 100-year floodplain near Greenville flood only once a century?
Not at all; a Washington County tract in that zone carries a 1-in-100 chance in any single year, so floods can come in back-to-back years.

Check the layer list in the MARIS Mississippi Statewide Parcels map viewer; if Washington County includes a floodplain layer, confirm the zone on FEMA's map anyway.
