Ahead of any purchase around Greenville, pull up the Greene County flood zone map: a mapped flood zone changes insurance, building rules and resale. What this Greene County guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the NYS Tax Parcels Public layer in ArcGIS Map Viewer.
Getting started with the Greene County flood zone map
If the land is near Cairo, flood zones come from FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. A tract near Jefferson Heights without an address can still be found: zoom in from the nearest road and click inside the land.
Where the parcel data lives
Parcels around Hudson River are published on the NYS Tax Parcels Public layer in ArcGIS Map Viewer, which opens without registering. Without an address in hand, pan along the nearest road until the lines appear, then click inside the one you want, for land near Ashland included. Closer to Catskill, copy the parcel ID from that panel; each office in the county will want it.
Neighboring parcel maps
Greene County touches Albany County, Columbia County, Delaware County, Rensselaer County, and Schoharie County, all with their own assessor records. Acreage along the edge near Haines Falls may show up in two county records, so open the adjacent map too. If you're looking near Greenville, our state page links every bordering county map across New York.
Reading A, AE and X
For a parcel near Greenville, A and V zones are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. For a home near Cementon, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
What the map can't tell you
Listed acreage is a tax-roll number; only a licensed surveyor can set the real lines on land around Ashland. On ground around Coxsackie, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so open the NYS Tax Parcels Public layer in ArcGIS Map Viewer next for the outline of the tract near Jefferson Heights.
Questions to ask before you buy
Near Haines Falls, request about past flood claims before closing; getting a quote early keeps the budget honest.
What a flood zone means for a buyer
Closer to Durham, get the Elevation Certificate if one exists: it compares the building to the BFE. Remodeling a house in a zone near Cementon can trigger elevation rules; check with the county or town building office early.
Recorded documents worth pulling
For anything that matters, request the recorded deed through the County Clerk; the parcel map near Jefferson Heights only summarizes it. Older tracts near Hudson River can trace back through a long string of deeds, so a title company earns its fee on a real sale.
Low spots and local drainage
Low-lying fields near Hudson River may not have detailed mapping, so look for water marks and debris lines. Wet ground around Haines Falls is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Who handles what
For assessment questions about property around Leeds go to the county Real Property Tax Services office, which maintains the tax roll. Building or septic questions for a lot near Coxsackie go to planning, building or health offices, and the answer depends on jurisdiction.
A quick look at the area
Catskill serves as the county seat, home to the main records offices. You'll also find Ashland, Athens, Cairo, and Coxsackie. Roughly 47,062 people live in Greene County (Census estimate, 2023) on roughly 647 square miles. Greene County was formed in 1800, and some chains of title near Leeds are long. Features like Hudson River make handy reference points on the map.
How land is described here
Rural deeds near Coxsackie commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Town lots near Hudson River refer to a recorded plat, making them easier to find. Write down the legal description for the tract near Coxsackie for any title or survey request.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Durham, though signal can drop in rural spots. A screenshot of the parcel near Jefferson Heights with its ID keeps working without signal.
Greene County: common questions
Is AE a high-risk flood zone in Greene County?
On ground around Leeds, AE is a Special Flood Hazard Area with a published base flood elevation; unnumbered A zones don't list one.
Can I challenge a flood zone near Durham?
For land near Haines Falls, a Letter of Map Amendment (LOMA) from FEMA can remove a structure on naturally high ground; a surveyor's elevation data supports it.
Do I need to worry about flooding in Zone X near East Durham?
Short answer: shaded X is moderate risk and unshaded X is minimal risk; many owners near East Durham buy coverage anyway.
How can I tell if a house near Haines Falls is in a flood zone?
For most people, FEMA's free map shows the zone for any spot near Jefferson Heights, which takes a couple of minutes.
Does the parcel map work on a phone around Jefferson Heights?
For acreage around Durham, no app is needed for most county viewers; screenshots help offline.
