Before you buy or build near Newfield, check the Ithaca flood zone map: the zone on that map shapes insurance, permits and resale. This Ithaca guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Tompkins County ArcGIS parcel map.
Getting started with the Ithaca flood zone map
Start with FEMA's Flood Map Service Center: search an address around Newfield, then open the map view for that panel. A tract near Dryden without an address can still be found: zoom in from the nearest road then click the parcel area.
Opening the official parcel viewer
Begin with the Tompkins County ArcGIS parcel map; it includes each assessed parcel in the county, Dryden included. For property near Danby, type a street address, an owner's name or a parcel number, and the matching parcel lights up. If you're looking near Caroline, write down the parcel ID before closing the panel; every clerk in the county uses it to find the file.
How land is described here
Older tracts around Newfield commonly use metes-and-bounds descriptions, which trace the boundary call by call. Platted lots around Lansing usually use lot and block from a recorded plat instead, making them easier to find. Write down the legal description for the tract near Newfield for any title or survey request.
When a parcel crosses a boundary
Tompkins County borders Cayuga County, Chemung County, Cortland County, Schuyler County, and Seneca County; every one of them runs a separate parcel map. Acreage along the edge near Newfield can be split in two county records, so open the adjacent map as well. In and around Newfield, our state page lists each bordering county map across New York.
Field tips
Most viewers work in a phone browser, useful out on a road near Caroline, though signal can drop in rural spots. A printout of the tract near Lansing is a good backup.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, plats and easements covering ground around Danby sit with the County Clerk. Older tracts near Groton may sit on a long string of deeds, so a title company is worth hiring on a real sale.
Ithaca, NY: the basics
Ithaca lies within Tompkins County, New York, so its parcels are on the county's map. As the county seat, Ithaca hosts the courthouse, handy when you need recorded documents. Local government in Ithaca handles things like zoning, permits and utilities inside its limits, while the county keeps the tax map. Lots just outside the town limits near Newfield generally falls under county rules instead.
Offices that can help
If the acreage or value on a parcel near Caroline looks off are handled by the county Real Property Tax Services office, the office behind the parcel record. Questions about what you can build around Groton need the planning or permitting office, town or county, depending on location.
Getting your bearings
Ithaca is the county seat, home to the main records offices. Other places on the map include Lansing, Danby, Newfield, and Dryden, where town lots give way to larger tracts. Roughly 103,558 people call Tompkins County home (Census Bureau estimate, 2023) across some 475 square miles. Tompkins County was organized in 1817, so old deeds can run back a long way.
Reading A, AE and X
An AE label carries a published BFE, which plain A zones lack; builders around Danby design to it. On ground around Newfield, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Beyond the mapped zones
Low-lying fields near Danby may not have detailed mapping, so ask neighbors about past flooding. Marshy spots near Newfield can limit building too; check the National Wetlands Inventory mapper for a first look.
Questions to ask before you buy
Ask the listing agent about past flood claims on the property near Groton; getting a quote early avoids surprises.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so open the Tompkins County ArcGIS parcel map next for the outline of the tract near Lansing.
Insurance, lenders and building
For a structure inside an A or V zone and the loan is federally backed or regulated, the lender will require flood insurance where the community participates in the National Flood Insurance Program, whether the land is near Danby or elsewhere in the county. Remodeling a house in a zone near Lansing often needs a floodplain permit; ask the local floodplain administrator early.
