The Cayuga County flood zone map: start here
Around Sherwood, flood zones come from FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. Rural land near Aurelius with no street number can still be found: search the nearest road and click inside the land.
Opening the official parcel viewer
Go first to the Cayuga County ArcGIS parcel map; it covers each tax parcel around Sherwood and Fleming. When a rural tract has no street number, follow the nearest road on the aerial and click the parcel itself, and that holds around Owasco Lake too. Near Lake Ontario National Marine Sanctuary, the parcel card normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Neighboring parcel maps
The county touches Cortland County, Jefferson County, Onondaga County, Oswego County, and Seneca County; every one of them runs a separate parcel map, at least around Fleming. A tract near the line by Brutus may show up across two assessors' files, so open the adjacent map as well. For a parcel near Kelloggsville, our state page lists every bordering county map across New York.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Sherwood, so load it before you lose signal. A saved image of the lot near Westbury and its lines helps when you meet an owner or agent.
Reading A, AE and X
Out toward Cato, A and V zones mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For acreage around Auburn, a shaded X area marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Lining it up with the parcel map
FEMA doesn't draw property lines, so check the Cayuga County ArcGIS parcel map too to see exactly which lot near Lake Ontario National Marine Sanctuary you're looking at.
Questions to ask before you buy
For a parcel near Sherwood, request about past flood claims before closing; an insurance quote early avoids surprises.
Getting answers from the right desk
Questions about value or the owner field for land near Brutus are handled by the county Real Property Tax Services office, which maintains the tax roll. Questions about what you can build around Aurelius go to planning, building or health offices, depending on whether the land is inside town limits.
Getting your bearings
Auburn is the county seat, where most land records are kept. You'll also find Aurelius, Brutus, Cato, and Conquest. Roughly 74,485 people call Cayuga County home (Census Bureau estimate, 2023) on about 692 square miles. The county was organized in 1799, so old deeds can run back a long way around Sherwood. Features like Owasco Lake, Cayuga Lake, and Montezuma National Wildlife Refuge help you orient on the aerial.
Limits of the parcel data
The acreage figure is an assessed number; just a licensed surveyor sets the real boundary on land around Lake Ontario National Marine Sanctuary. For a tract near Lake Ontario National Marine Sanctuary, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Lenders and permits
With a lot near Aurelius, ask for an Elevation Certificate: it records the building's elevation against the base flood. Building or adding on near Lake Ontario National Marine Sanctuary in a mapped zone often needs a floodplain permit; ask the local floodplain administrator before you plan.
Water near Genoa
Low-lying fields near Lake Ontario National Marine Sanctuary may not have detailed mapping, so ask neighbors about past flooding. Wetlands near Fleming can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Where the recorded documents are
With a lot near Westbury, the map is an index, not the title: deeds, plats and easements for parcels in the county sit with the County Clerk. Older tracts around Genoa may sit on many deeds, so a title company earns its fee if money is changing hands.
Cayuga County: common questions
Is there a flood layer on the parcel viewer near Lake Ontario National Marine Sanctuary?
It depends, but a flood layer may appear in the Cayuga County ArcGIS parcel map layer list, but FEMA's own map is the official source.
Is AE a high-risk flood zone for land near Brutus?
If you're looking near Brutus, both are high-risk zones, but only AE has a base flood elevation; unnumbered A zones don't list one.
How can I tell if a house near Conquest is in a flood zone?
Usually, search the address near Aurelius on FEMA's Flood Map Service Center, and the zone code appears on the map.
Is Zone X safe from flooding around Sherwood?
It depends, but Zone X near Cato means moderate (shaded) or minimal (unshaded) mapped risk; FEMA notes that a large share of claims come from these areas.
Does the parcel map work on a phone in Cayuga County?
Near Brutus, no app is needed for most county viewers; screenshots help offline.
