Weighing a property around Lowman? A quick look at the Chemung County flood zone map shows whether the lot falls inside a mapped floodplain, and no account is needed. In this county guide: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the county ArcGIS parcel map for land near Catlin.
Where the Chemung County flood zone map lives
Start with FEMA's Flood Map Service Center: type an address near Baldwin, and pick the FIRMette or map view. Vacant ground around Catlin is still easy to locate: search the nearest road then click the parcel area.
The viewer Chemung County publishes
Begin with the Chemung County ArcGIS parcel map; it covers every assessed parcel from Catlin to Lowman. For acreage around Ashland, enter 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 Elmira, write down the parcel ID before closing the panel; every office in the county will want it.
Reading A, AE and X
For a home near Catlin, zones beginning with A or V are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. For a home near Erin, shaded Zone X is moderate risk, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so pair it with the Chemung County ArcGIS parcel map to confirm you have the right parcel near Erin.
Legal descriptions in New York
Rural deeds near Big Flats are often described by metes and bounds, which trace the boundary call by call. Platted lots around Erin are typically described by lot and block, making them easier to find. Keep the legal description for land near Erin for any title or survey request.
Neighboring parcel maps
Chemung County touches Schuyler County, Steuben County, Tioga County, Tompkins County, and Bradford County, PA, and each of those keeps its own parcel map. A tract near the line by Lowman may show up in two county records, so check the neighboring map as well. For a parcel near Catlin, our state page lists each neighboring county map for New York.
Taking the map into the field
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Erin, but coverage can be spotty out of town. A printout of the tract near Catlin keeps working without signal.
What to request from a seller
With a lot near Erin, request for any Elevation Certificate before closing; getting a quote early keeps the budget honest.
Beyond the mapped zones
Low-lying fields near Erin may not have detailed mapping, so walk the land after rain. Wet ground around Big Flats is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Which office to call
Questions about value or the owner field for land near Baldwin go to the county Real Property Tax Services office, since that office keeps the assessment data. Questions about what you can build around Baldwin go to planning, building or health offices, depending on whether the land is inside town limits.
Where the recorded documents are
Before you sign anything, pull the recorded deed from the County Clerk; the viewer just points to it, which applies near Ashland as much as anywhere. For acreage around Lowman, bring the instrument number shown in the record panel and the lookup takes minutes.
Places you'll see on the map
Elmira serves as the county seat, home to the main records offices. You'll also find Ashland, Baldwin, Big Flats, and Catlin. Roughly 81,325 people live in Chemung County (Census Bureau estimate, 2023) on roughly 407 square miles. The county was formed in 1836, so old deeds can run back a long way, at least around Ashland.
Before you lean on the lines
On ground around Baldwin, listed acreage is an assessed number; just a licensed surveyor sets the real corners on the ground. On ground around Lowman, owner names and values update on a schedule, so a deed recorded last month may not show yet.
What a flood zone means for a buyer
For a parcel near Ashland, ask for an Elevation Certificate: it compares the building to the BFE. New construction in a floodplain near Lowman often needs a floodplain permit; ask the local floodplain administrator early.
Quick answers
Does the county parcel map show flood zones around Lowman?
