Before you buy or build near Watervliet, look at the Cohoes flood zone map: the zone on that map shapes insurance, permits and resale. This Cohoes guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
Getting started with the Cohoes flood zone map
The official source is FEMA's Flood Map Service Center: search an address around Menands, then open the map view for that panel. Vacant ground around Colonie can still be found: search the nearest road and click the spot.
Getting to the right map
Begin with the Albany County ArcGIS parcel map; it covers every tax parcel in the county, Voorheesville included. When a rural tract has no street number, follow Interstate 787 on the aerial and select the outline. If the land is near Albany, write down the parcel ID while you have it open; each clerk in the county will want it.
Questions to ask before you buy
Ask the seller for any Elevation Certificate for the house near Watervliet; an insurance quote early avoids surprises.
Neighboring parcel maps
Albany County meets Columbia County, Greene County, Rensselaer County, Saratoga County, and Schenectady County; every one of them runs a separate parcel map. Ground near Green Island that runs to the line may show up across two assessors' files, so look at the adjacent map before you assume the acreage. With a lot near Watervliet, the Platbookmapper state page lists each neighboring county map across New York.
Water near Voorheesville
Creeks and ditches near Colonie may not have detailed mapping, so look for water marks and debris lines. Wet ground around Voorheesville is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Albany County in a few facts
Albany serves as the county seat, where most land records are kept. Smaller places on the map include Green Island, Watervliet, Menands, and Colonie, each with its own cluster of lots. Around 316,659 people call Albany County home (Census estimate, 2023) spread over some 523 square miles. Albany County dates to 1683, so old deeds can run back a long way. Places such as Mohawk River, Hudson River, and Thompson's Lake State Park make handy reference points on the map near Voorheesville.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Voorheesville, but coverage can be spotty out of town. A screenshot of the parcel near Menands with its ID is a good backup.
City limits and county records
Cohoes sits in Albany County, New York, and the county assessor maps its lots. In and around Colonie, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the city limits out by Watervliet often follows county rules instead.
Reading A, AE and X
For land near Menands, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For land near Colonie, a low-risk label isn't a guarantee: FEMA notes that many claims come from moderate- and low-risk areas.
A word on accuracy
Tax maps are drawn for assessment, not measured on the ground, so a fence near Watervliet can sit a few yards off the line on screen. With a lot near Watervliet, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Deeds, plats and who keeps them
For anything that matters, pull the recorded deed through the County Clerk; the parcel map near Voorheesville only summarizes it. Long-held tracts near Colonie can go back through several deeds, so a title company earns its fee before a purchase.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so check the Albany County ArcGIS parcel map too for the outline of the tract near Menands.
Insurance, lenders and building
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, mandatory purchase rules apply where the community participates in the National Flood Insurance Program, which applies near Colonie as much as anywhere. New construction in a floodplain near Colonie can trigger elevation rules; ask the local floodplain administrator early.
Cohoes: common questions
Does the county parcel map show flood zones in Cohoes?
Good question; a flood layer may appear in the Albany County ArcGIS parcel map layer list, but FEMA's own map is the official source.
Can I challenge a flood zone near Albany?
Generally, you can ask FEMA for a LOMA if surveyed elevations show the building near Menands is above the BFE, and lenders accept the result.
What does an AE label mean for a lot near Albany?
Usually, AE is a Special Flood Hazard Area with a published base flood elevation, so builders near Colonie design to that elevation.
Is my property near Menands in a flood zone?
Look up the spot near Watervliet in FEMA's National Flood Hazard Layer viewer, and the zone code appears on the map.
Who keeps deeds for property in Cohoes?
The county Real Property Tax Services office handles values and the tax roll, and the County Clerk keeps deeds, while zoning questions go to planning

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.
