Weighing a property around Ashland? A quick look at the Horseheads flood zone map shows whether FEMA puts it in a high-risk zone, and it costs nothing to check. What this Horseheads guide covers: locating a parcel on FEMA's map, reading the zone codes, and confirming the outline on the county map.
The Horseheads flood zone map: start here
Start with FEMA's Flood Map Service Center: search an address around Van Etten, and choose the dynamic map. Rural land near Van Etten with no street number is still easy to locate: pan from the closest town and click inside the land.
Pulling up a parcel
Begin with the Chemung County ArcGIS parcel map; it covers every tax parcel from Van Etten to Southport. If the land is near Southport, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a tract near Van Etten, the parcel card normally shows the owner of record, acreage on the tax roll, a parcel ID and in many cases the last transfer.
Where the recorded documents are
The map is an index, not the title: deeds, subdivision plats and easements for land near Big Flats are kept by the County Clerk. Older tracts around Ashland may sit on many deeds, and a title company is worth hiring on a real sale.
Places you'll see on the map
Elmira holds the county offices, home to the main records offices. Other places on the map include Big Flats, Southport, and Erin, where town lots give way to larger tracts. Around 81,325 people live in Chemung County (Census Bureau estimate, 2023) spread over roughly 407 square miles. Chemung County was formed in 1836, and some chains of title near Erin are long.
What the map can't tell you
Acreage on the record is an estimate; just a licensed surveyor establishes the real lines on land around Ashland. Near Southport, records update in batches, so a deed recorded last month might lag behind.
Reading the legal description
Older tracts around Southport commonly use metes-and-bounds descriptions, listing bearings, distances and landmarks. Subdivision lots in Van Etten refer to a recorded plat, which is simpler to follow. Write down the legal description for the tract near Elmira when you talk to a surveyor.
Where Horseheads fits in
Horseheads is part of Chemung County, New York, so its parcels are on the county's map. For a parcel near Van Etten, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the town limits out by Ashland usually falls under county rules, not municipal ones.
Which office to call
Questions about value or the owner field for land near Elmira are handled by the county Real Property Tax Services office, since that office keeps the assessment data. Building or septic questions for a lot near Erin need the planning or permitting office, and the answer depends on jurisdiction.
Zones on the Horseheads flood zone map
Zone AE includes a base flood elevation (BFE), while plain Zone A does not; surveyors near Elmira use that number. In and around Southport, a low-risk label isn't a guarantee: FEMA notes that many claims come from moderate- and low-risk areas.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so pair it with the Chemung County ArcGIS parcel map for the outline of the tract near Big Flats.
Beyond the mapped zones
Creeks and ditches near Elmira aren't always studied in detail, so walk the land after rain. Wet ground around Southport is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
What to request from a seller
Ask the seller for any Elevation Certificate on the property near Ashland; an insurance quote early keeps the budget honest.
Insurance, lenders and building
If the land is near Elmira, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. Building or adding on near Ashland in a mapped zone usually means extra permit review; call the permitting office before you plan.
Field tips
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Southport, so load it before you lose signal. A screenshot of the parcel near Big Flats with its ID helps when you meet an owner or agent.
