When a deed near Big Flats says lot and block, you'll need the Horseheads plat map to make sense of it. What this Horseheads guide covers: where to request a copy, plat versus tax map, and the details that matter to buyers.
Getting started with the Horseheads plat map
For a lot in Horseheads, the deed usually cites the plat; that makes the request quick.
Pulling up a parcel
Begin with the Chemung County ArcGIS parcel map; it covers each assessed parcel around Big Flats and Van Etten. If you're looking near Ashland, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a home near Big Flats, write down the parcel ID before closing the panel; each clerk in the county uses it to find the file.
Amended plats
Lots near Big Flats can be combined or reconfigured by a replat, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Where Horseheads fits in
Horseheads sits in Chemung County, New York, so its parcels are on the county's map. For a tract near Elmira, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the town limits out by Big Flats often falls under county rules, not municipal ones.
Places you'll see on the map
Elmira holds the county offices, which is where the courthouse records live. Smaller places on the map include Big Flats, Southport, and Erin, each with its own cluster of lots. Around 81,325 people live in Chemung County (Census estimate, 2023) across some 407 square miles. Chemung County was organized in 1836, which matters when you trace an old farm's title.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Elmira, though signal can drop in rural spots. A screenshot of the parcel near Erin with its ID keeps working without signal.
When a parcel crosses a boundary
Chemung County meets Schuyler County, Steuben County, Tioga County, Tompkins County, and Bradford County, PA, all with their own assessor records. Ground near Southport that runs to the line may be split across two assessors' files, so open the adjacent map before you assume the acreage. For land near Big Flats, the Platbookmapper state page lists every neighboring county map across New York.
Metes and bounds instead
Acreage around Southport outside a subdivision may have no plat at all; look for a recorded survey for land near Big Flats.
Two different maps
The Chemung County ArcGIS parcel map draws parcels for taxes, whereas the plat carries surveyed dimensions.
Which office to call
For assessment questions about property around Erin are handled by the county Real Property Tax Services office, since that office keeps the assessment data. Questions about what you can build around Van Etten go to planning, building or health offices, town or county, depending on location.
Sections, lots and bearings
Tracts outside towns near Elmira commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Town lots near Elmira refer to a recorded plat, which is simpler to follow. Keep the legal description for land near Erin before you request a deed or survey.
Deeds, plats and who keeps them
Before you sign anything, pull the recorded deed through the County Clerk; the parcel map near Van Etten only summarizes it. For a tract near Southport, have ready the instrument number listed on the parcel record to skip a name search.
Reading the plat sheet
For a home near Elmira, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
A word on accuracy
Acreage on the record is an assessed number; just a licensed surveyor can set the real boundary for a parcel near Erin. For a tract near Van Etten, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Requesting the plat
Out toward Van Etten, some counties put plat images online, while others require a visit or a request; small fees are common.
