Ahead of any purchase around Bennington, pull up the Wyoming County flood zone map: FEMA's zone label affects insurance, building rules and resale.

The Wyoming County flood zone map: start here
With a lot near Bennington, the official source is FEMA's Flood Map Service Center: enter the street address, then open the map view for that panel. Vacant ground around Castile is still easy to locate: pan from the closest town and click the spot.
Pulling up a parcel
Your first stop is the NYS Tax Parcels Public layer in ArcGIS Map Viewer; it includes every tax parcel from Portageville to Warsaw. Without an address in hand, pan along the nearest road until the lines appear, then click inside the one you want, which applies near North Java as much as anywhere. For a tract near Portageville, write down the parcel ID from that panel; each office in the county will want it.
Neighboring parcel maps
Wyoming County borders Allegany County, Cattaraugus County, Erie County, Genesee County, and Livingston County, and each of those keeps its own parcel map. A tract near the line by Silver Lake Institute can show up across two assessors' files, so check the neighboring map too. For a parcel near Portageville, our state page links each neighboring county map across New York.
A word on accuracy
With a lot near Covington, listed acreage is an estimate; just a licensed surveyor establishes the real boundary on the ground. Owner names and values update on a schedule, so a recent sale near Silver Lake Institute can take weeks to appear.
Places you'll see on the map
Warsaw is the county seat, home to the main records offices. You'll also find Arcade, Attica, Bennington, and Castile, each with its own cluster of lots. Around 39,532 people call Wyoming County home (Census estimate, 2023) across some 593 square miles. Wyoming County was organized in 1841, which matters when you trace an old farm's title.
What to request from a seller
Request whether the home has flooded on the property near North Java; an insurance quote early keeps the budget honest.
Which office to call
If the acreage or value on a parcel near Arcade looks off belong with the county Real Property Tax Services office, which maintains the tax roll. Building or septic questions for a lot near Bennington go to planning, building or health offices, town or county, depending on location.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Silver Lake Institute, so load it before you lose signal. A screenshot of the parcel near Arcade with its ID helps when you meet an owner or agent.
Zones on the Wyoming County flood zone map
For a home near Portageville, any A or V zone mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. With a lot near Warsaw, a low-risk label isn't a guarantee: FEMA notes that floods happen outside mapped zones too.
Legal descriptions in New York
Older tracts around Arcade are often described by metes and bounds, a series of courses and distances from a starting point. Platted lots around Warsaw usually use lot and block from a recorded plat instead, which is simpler to follow. Copy the legal description from the record for the parcel near Castile before you request a deed or survey.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so check the NYS Tax Parcels Public layer in ArcGIS Map Viewer too to confirm you have the right parcel near Arcade.
Insurance, lenders and building
With a lot near Attica, ask for an Elevation Certificate: it can change the insurance price a lot. New construction in a floodplain near Covington often needs a floodplain permit; ask the local floodplain administrator early.
Water near Covington
Small streams around Silver Lake Institute aren't always studied in detail, so walk the land after rain. Wet ground around North Java is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
