Before an offer near Geneva, pull up the Canandaigua flood zone map: FEMA's zone label affects insurance, permits and resale. This Canandaigua guide covers: locating a parcel on FEMA's map, reading the zone codes, and confirming the outline on the county map.
Checking the Canandaigua flood zone map step by step
Start with FEMA's Flood Map Service Center: search an address around Phelps, then open the map view for that panel. Vacant ground around Gorham is still easy to locate: zoom in from the nearest road then click the parcel area.
Where the parcel data lives
Go first to the Ontario County parcel viewer; it maps every assessed parcel in the county, Gorham included. For acreage around Phelps, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. Out toward Victor, the parcel card normally shows the owner of record, acreage on the tax roll, a parcel ID and in many cases the last transfer.
A short flood checklist
Ask the listing agent for any Elevation Certificate on the property near Geneva; getting a quote early avoids surprises.
Canandaigua and the county around it
Canandaigua is part of Ontario County, New York, so its parcels are on the county's map. As the county seat, Canandaigua hosts the courthouse, so deeds and plats are filed in town. For acreage around Gorham, the municipality handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the town limits out by Phelps generally answers to county rules instead.
Zones on the Canandaigua flood zone map
An AE label comes with a base flood elevation, and an unnumbered A zone has none; surveyors near Geneva use that number. With a lot near Victor, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Parcel lines plus flood zones
Where a floodplain cuts across acreage near Naples, the structure's footprint is the key question.
Money questions tied to the zone
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, flood insurance is generally required in communities in the NFIP, and that holds around Victor too. Remodeling a house in a zone near Gorham usually means extra permit review; call the permitting office early.
Limits of the parcel data
Listed acreage is an assessed number; only a licensed surveyor can set the real boundary on land around Phelps. For land near Phelps, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Reading the legal description
Rural deeds near Naples are often described by metes and bounds, which trace the boundary call by call. Platted lots around Naples usually use lot and block from a recorded plat instead, which is simpler to follow. Copy the legal description from the record for the parcel near Phelps when you talk to a surveyor.
Next door to Ontario County
Ontario County touches Livingston County, Monroe County, Seneca County, Steuben County, and Wayne County, and each of those keeps its own parcel map. A tract near the line by Phelps may be split in two county records, so look at the neighboring map as well. For a parcel near Manchester, the Platbookmapper state page links each neighboring county map for New York.
Beyond the mapped zones
Low-lying fields near Phelps aren't always studied in detail, so ask neighbors about past flooding. Wet ground around Phelps is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
The paper trail behind a parcel
For anything that matters, get the recorded deed through the County Clerk; the viewer just points to it, whether the land is near Gorham or elsewhere in the county. Near Gorham, have ready the document number from the tax record and the lookup takes minutes.
Places you'll see on the map
Canandaigua serves as the county seat, where most land records are kept. Other places on the map include Manchester, Victor, Gorham, and Phelps, each with its own cluster of lots. Around 112,494 people call Ontario County home (Census estimate, 2023) on roughly 644 square miles. Ontario County was organized in 1789, and some chains of title near Geneva are long.
