An Otsego County flood zone map check belongs in the due diligence for any Otsego County property, from a house lot in Cooperstown to farm ground near Butternuts. For any tract in Otsego County, New York, the answer affects insurance, permits and resale.
We'll cover finding an Otsego County address on FEMA's map, what Zone A, AE and X mean, how the county viewer fits in, and what to do if the map looks wrong.
Look up the Otsego County flood zone map step by step
Start at the FEMA Flood Map Service Center and enter the property address in Cherry Valley or anywhere else in the county. If a tract around Edmeston has no street number yet, search the nearest road and pan to it. On acreage outside Cherry Valley, FEMA's National Flood Hazard Layer viewer draws the zones over aerial imagery, so you can see if the shading reaches a house near Edmeston. Then open the NYS Tax Parcels Public layer in ArcGIS Map Viewer for Otsego County to confirm the parcel near Cherry Valley. The Otsego County record gives the parcel number and legal description that an insurer or lender near Cherry Valley may ask for.
Finding the tract on the Otsego County map
For Otsego County, the free public parcel layer is state-run: open the NYS Tax Parcels Public layer in ArcGIS Map Viewer and pan to Cherry Valley.

Our Otsego County, NY page keeps the official link and the maps next door to Cherry Valley in one place.
Reading the zones on an Otsego County flood map
Any Otsego County parcel shaded as Zone A, AE, AH or AO sits in what FEMA calls a Special Flood Hazard Area, meaning FEMA estimates a 1-percent annual chance of flooding. A surveyor working near Cherry Valley uses the base flood elevation printed for AE zones; unnumbered A zones do not have one. If an Otsego County parcel displays shaded Zone X, it is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded X (or C) on the Otsego County panel means minimal risk.
Low ground and small streams around Cherry Valley
A creek near Edmeston that displays no detailed zone, so treat an unmapped channel as a reason to ask questions, not proof the ground stays dry.
A short buyer checklist for Butternuts
Request any past flood claims history for an Otsego County property before closing; it tells you more than the map alone. Quotes for land near Fly Creek depend on the zone and the building's elevation, so bring both to the agent.
Reading the fine print on an Otsego County panel
The FIRM panel for Otsego County carries an effective date; if it is old, ask the county floodplain office if new maps for land near Edmeston are in progress. A floodway on a county panel marks the part of the floodplain that carries the main flow, and it is treated more strictly than the rest of the zone near Fly Creek.
When the map affects a deal
The zone displays up again when a loan on a house near Edmeston is underwritten. When an Otsego County home is mapped in a high-risk zone and carries a federally backed mortgage, flood insurance is mandatory, as long as Otsego County or the town participates in the NFIP. Outside the A zones around Edmeston, coverage is optional, although some lenders require it anyway. If a building near Edmeston sits above the flood line, FEMA's LOMA process allows a review, supported by elevation data from a professional surveyor. Placing fill on low ground near Cherry Valley generally needs a floodplain permit, so call the county or the town office in Cherry Valley before work starts.
