The sections below go from the FEMA search to the Chautauqua County parcel record, then cover insurance, permits and map changes near Mayville.
How to check the Chautauqua County flood zone map
Start at the FEMA Flood Map Service Center and enter the property address in Busti or anywhere else in the county. Search returns the effective FIRM panel for the spot in Chautauqua County, plus any pending changes FEMA has posted. For an irregular lot near Charlotte, try FEMA's National Flood Hazard Layer viewer, which displays how much of a county parcel sits inside the zone. Switch to the Chautauqua County ArcGIS parcel map and track down the same tract close to Charlotte. If the Chautauqua County viewer has a floodplain layer, treat it as a convenience copy and confirm on FEMA's map.

For land around Carroll, open the Chautauqua County ArcGIS parcel map (an Esri ArcGIS web map); it is the map Chautauqua County itself publishes. Use the search box for an address in Busti or a parcel number, or simply zoom in and click a tract close to Carroll. Bookmark our Chautauqua County page too; it tracks the official New York link if it moves and lists the maps around Busti.
Zone A, AE and X in plain English
On the FIRM covering Chautauqua County, zones that start with A or V are Special Flood Hazard Areas, defined by a 1-percent annual chance of being flooded. Where a Chautauqua County tract displays Zone AE, there's a base flood elevation to compare a building against; in Zone A there is not one. If a Chautauqua 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 Charlotte is minimal risk.
Deeds and plats behind the Chautauqua County map
The parcel layer for Chautauqua County points back to recorded deeds and plats, kept by the county's recording office (its title varies by state). Easements and access rights near Cherry Creek live in recorded documents, so read the deed, not just the county map.

When the map affects a deal
Insurance is the practical stake for a Chautauqua County buyer. When a county home is mapped in a high-risk zone and carries a federally backed mortgage, flood insurance is mandatory; that applies where the local government around Charlotte is in the National Flood Insurance Program. Outside the A zones around Charlotte, coverage is optional, though a lender in New York can still ask for it. Where a structure near Busti looks higher than the shading suggests, the landowner can ask FEMA for a Letter of Map Amendment (LOMA); a surveyor near Charlotte can supply the elevation data. New construction in a Chautauqua County Special Flood Hazard Area often requires a permit and an elevation check, so call the county or the town office in Busti before work starts.
Chautauqua County, NY: common questions
Can I build in a flood zone in Chautauqua County?
Building in a Special Flood Hazard Area near Charlotte usually needs a floodplain permit and may require elevating the structure, so check with the county floodplain administrator.
Does the Chautauqua County parcel map display flood zones?
Check the layer list in the Chautauqua County ArcGIS parcel map; if Chautauqua County includes a floodplain layer, confirm the zone on FEMA's map anyway.
What is a base flood elevation for a Chautauqua County property?
For a Chautauqua County property in Zone AE, the base flood elevation marks how high the 100-year flood is expected to rise, and it is printed in AE zones.
Is my Charlotte address in a flood zone?
Look it up at FEMA's Flood Map Service Center, then match the parcel lines in the Chautauqua County ArcGIS parcel map; for land near Mayville, a zone starting with A or V is high risk.
Is flood insurance required for a Zone X lot in Charlotte?
