Weighing a property around Erin? Checking the Elmira flood zone map reveals whether the lot falls inside a mapped floodplain, and the lookup is free. In this Elmira guide: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Chemung County ArcGIS parcel map.
Getting started with the Elmira flood zone map
The official source is FEMA's Flood Map Service Center: type an address near Southport, then open the map view for that panel. A tract near Big Flats without an address is still easy to locate: search the nearest road and click the spot.
The free map to start with
Go first to the Chemung County ArcGIS parcel map; it maps every tax parcel in the county, Erin included. In and around Horseheads, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. Near Van Etten, the record panel typically gives the owner of record, acreage on the tax roll, the parcel number and sometimes recent sales.
Elmira, NY: the basics
Elmira is part of Chemung County, New York, and the county assessor maps its lots. Elmira is also the county seat, handy when you need recorded documents. For a parcel near Erin, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the town limits out by Ashland often falls under county rules, not municipal ones.
Sections, lots and bearings
Older tracts around Big Flats commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Subdivision lots in Big Flats are typically described by lot and block, which is simpler to follow. Write down the legal description for the tract near Horseheads when you talk to a surveyor.
What the zone letters mean
An AE label includes a base flood elevation (BFE), while plain Zone A does not; builders around Southport design to it. In and around Ashland, a low-risk label isn't a guarantee: according to FEMA, floods happen outside mapped zones too.
Getting answers from the right desk
Questions about value or the owner field for land near Van Etten go to the county Real Property Tax Services office, since that office keeps the assessment data. Zoning, permits and septic questions near Southport go to planning, building or health offices, depending on whether the land is inside town limits.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so check the Chemung County ArcGIS parcel map too for the outline of the tract near Van Etten.
Deeds, plats and who keeps them
When the details count, pull the recorded deed from the County Clerk; the parcel map near Southport only summarizes it. On ground around Big Flats, have ready the instrument number shown in the record panel to skip a name search.
Water near Horseheads
Creeks and ditches near Van Etten aren't always studied in detail, so look for water marks and debris lines. Wetlands near Horseheads can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Questions to ask before you buy
Request about past flood claims on the property near Erin; getting a quote early avoids surprises.
When a parcel crosses a boundary
Chemung County touches Schuyler County, Steuben County, Tioga County, Tompkins County, and Bradford County, PA; every one of them runs a separate parcel map. A tract near the line by Ashland may show up in two county records, so check the neighboring map too. For land near Ashland, the Platbookmapper state page lists each neighboring county map across New York.
What the map can't tell you
Tax maps are drawn for assessment, not surveyed, so a tree line near Erin may sit some distance off the line on screen. On ground around Big Flats, owner names and values update on a schedule, so a deed recorded last month might lag behind.
What a flood zone means for a buyer
Out toward Ashland, ask for an Elevation Certificate: it records the building's elevation against the base flood. Building or adding on near Erin in a mapped zone usually means extra permit review; ask the local floodplain administrator before you plan.
Quick answers
Do I need to worry about flooding in Zone X around Ashland?
Zone X near Erin means moderate (shaded) or minimal (unshaded) mapped risk; FEMA notes that a large share of claims come from these areas.
Can I see flood zones on the Chemung County ArcGIS parcel map?
A flood layer may appear in the Chemung County ArcGIS parcel map layer list; confirm a lot near Erin on FEMA's map either way.
What is a LOMA around Southport?
Generally, you can ask FEMA for a LOMA if surveyed elevations show the building near Southport is above the BFE; it starts with an elevation survey.
Is AE a high-risk flood zone in Elmira?
Usually, an AE zone has a 1% annual chance of flooding and a base flood elevation, so builders near Big Flats design to that elevation.
Where do I ask about an assessment near Van Etten?
The county Real Property Tax Services office handles values and the tax roll, and the County Clerk keeps deeds; planning offices cover zoning near Van Etten

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
