Before an offer near Garbutt, look at the Monroe County flood zone map: the zone on that map shapes insurance, building rules and resale. What this Monroe County guide covers: the free FEMA tools, what each zone label means, lender insurance rules and what a LOMA is.
The Monroe County flood zone map: start here
Closer to Greece, start with FEMA's Flood Map Service Center: enter the street address, then open the map view for that panel. A tract near Chili without an address is still easy to locate: zoom in from Interstate 490 and click the spot.
Pulling up a parcel
Lots and tracts near Greece can be looked up on the Monroe County parcel viewer, free to use and open without a login. Without an address in hand, follow Interstate 490 on the aerial and select the outline. If the land is near Adams Basin, copy the parcel ID before closing the panel; every office in the county will want it.
Taking the map into the field
Most viewers work in a phone browser, useful out on a road near Clarkson, though signal can drop in rural spots. A saved image of the lot near Garbutt and its lines is a good backup.
Getting your bearings
Rochester is the county seat, which is where the courthouse records live. You'll also find Brighton, Chili, Clarkson, and East Rochester, where town lots give way to larger tracts. Around 748,482 people live in Monroe County (Census estimate, 2023) across some 657 square miles. The county was organized in 1821, and some chains of title near Brighton are long.
Neighboring parcel maps
Monroe County borders Genesee County, Livingston County, Ontario County, Orleans County, and Wayne County, all with their own assessor records. Ground near Gates Center that runs to the line can be split across two assessors' files, so look at the neighboring map before you assume the acreage. Out toward Brighton, the Platbookmapper state page links every bordering county map across New York.
Zones on the Monroe County flood zone map
For land near Brighton, A and V zones mark the Special Flood Hazard Area, land with a 1-percent chance of flooding in any year. If you're looking near Adams Basin, shaded Zone X is moderate risk, roughly the 100- to 500-year range; plain X, or C on older maps, means minimal mapped risk.
Parcel lines plus flood zones
If only part of a parcel near Brighton is shaded, what matters is where the building sits.
What to request from a seller
For property near Bushnell's Basin, request for any Elevation Certificate before closing; an insurance quote early avoids surprises.
Water near Garbutt
Small streams around Clarkson aren't always studied in detail, so look for water marks and debris lines. Wet ground around Brighton is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
What the map can't tell you
Acreage on the record is a tax-roll number; only a licensed surveyor can set the real lines for a parcel near Clarkson. Owner names and values update on a schedule, so a recent sale near Gates can take weeks to appear.
The paper trail behind a parcel
When the details count, request the recorded deed through the County Clerk; the parcel map near Bushnell's Basin only summarizes it. For property near Clarkson, have ready the document number from the tax record and the lookup takes minutes.
What a flood zone means for a buyer
If a building sits in a Special Flood Hazard Area and the loan is federally backed or regulated, flood insurance is generally required where the community participates in the National Flood Insurance Program, and that holds around Gates too. New construction in a floodplain near Brighton usually means extra permit review; call the permitting office early.
How land is described here
Older tracts around Gates are often described by metes and bounds, listing bearings, distances and landmarks. Subdivision lots in Bushnell's Basin are typically described by lot and block, which is simpler to follow. Copy the legal description from the record for the parcel near Bushnell's Basin for any title or survey request.
Which office to call
If the acreage or value on a parcel near Bushnell's Basin 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 Adams Basin are for the local planning and health departments, and the answer depends on jurisdiction.
Questions about the Monroe County flood zone map
What is a LOMA around Brighton?
Good question; you can ask FEMA for a LOMA if surveyed elevations show the building near Gates Center is above the BFE; a surveyor's elevation data supports it.
Is AE a high-risk flood zone around Bushnell's Basin?
If you're looking near Gates, AE is a Special Flood Hazard Area with a published base flood elevation; unnumbered A zones don't list one.
Can I see flood zones on the county parcel viewer near Gates Center?
It depends, but a flood layer may appear in the Monroe County parcel viewer layer list, though it can lag behind FEMA's current panels.
Why does the BFE matter near Adams Basin?
Good question; a BFE near Chili tells builders how high the lowest floor should be, and an Elevation Certificate compares the building to it.
Is the parcel map a survey around Clarkson?
Closer to Garbutt, parcel lines are tax drawings, not surveys, so a fence may sit off the line

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.
