Weighing a property around Canton? Checking the Massena flood zone map reveals whether it sits in a FEMA flood zone, and it costs nothing to check. What this Massena guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the NYS Tax Parcels Public layer in ArcGIS Map Viewer.
The Massena flood zone map: start here
Flood zones come from FEMA's Flood Map Service Center: type an address near Waddington, and choose the dynamic map. Rural land near Waddington with no street number can still be found: zoom in from the nearest road and click inside the land.
The free map to start with
Go first to the NYS Tax Parcels Public layer in ArcGIS Map Viewer; it maps each assessed parcel around Norfolk and Potsdam. When a rural tract has no street number, zoom in from Canton and select the outline. Near Brasher, the record panel typically gives the owner of record, acreage on the tax roll, the parcel number and often a sale date.
Where Massena fits in
Massena lies within St. Lawrence County, New York, so its parcels are on the county's map. For a tract near Waddington, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the town limits out by Potsdam often falls under county rules, not municipal ones.
Water near Norfolk
Creeks and ditches near Madrid may not have detailed mapping, so walk the land after rain. Wet ground around Madrid is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Places you'll see on the map
Canton holds the county offices, where most land records are kept. Smaller places on the map include Norfolk, Waddington, Madrid, and Potsdam, where town lots give way to larger tracts. Around 106,940 people call St. Lawrence County home (Census Bureau estimate, 2023) spread over about 2,680 square miles. St. Lawrence County was organized in 1802, so old deeds can run back a long way. Places such as Oswegatchie River and Cranberry Lake help you orient on the aerial around Brasher.
Sections, lots and bearings
Tracts outside towns near Potsdam are often described by metes and bounds, which trace the boundary call by call. Town lots near Norfolk are typically described by lot and block, which is simpler to follow. Write down the legal description for the tract near Potsdam for any title or survey request.
What to request from a seller
Ask the listing agent about past flood claims for the house near Potsdam; an insurance quote early keeps the budget honest.
Reading A, AE and X
Zone AE carries a published BFE, which plain A zones lack; builders around Brasher design to it. For land near Canton, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so check the NYS Tax Parcels Public layer in ArcGIS Map Viewer too to confirm you have the right parcel near Norfolk.
Which office to call
If the acreage or value on a parcel near Potsdam looks off are handled by the county Real Property Tax Services office, since that office keeps the assessment data. Questions about what you can build around Brasher go to planning, building or health offices, depending on whether the land is inside town limits.
A word on accuracy
The acreage figure is an estimate; just a licensed surveyor sets the real lines for a parcel near Norfolk. With a lot near Waddington, records update in batches, so a deed recorded last month might lag behind.
Lenders and permits
For property near Brasher, get the Elevation Certificate if one exists: it compares the building to the BFE. New construction in a floodplain near Waddington can trigger elevation rules; ask the local floodplain administrator early.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, subdivision plats and easements for land near Madrid sit with the County Clerk. Long-held tracts around Brasher may sit on a long string of deeds, and a title company is worth hiring on a real sale.
Massena: common questions
Is my property near Norfolk in a flood zone?
It depends, but search the address near Norfolk on FEMA's Flood Map Service Center, and the zone code appears on the map.
Does the county parcel map show flood zones for land near Norfolk?
Generally, a flood layer may appear in the NYS Tax Parcels Public layer in ArcGIS Map Viewer layer list; confirm a lot near Brasher on FEMA's map either way.
What is a LOMA around Waddington?
In most cases, FEMA's LOMA process is the usual route when a building near Madrid sits above the base flood elevation, and lenders accept the result.
Is Zone X safe from flooding in Massena?
Zone X near Canton means moderate (shaded) or minimal (unshaded) mapped risk; FEMA notes that a large share of claims come from these areas.
Can I print the parcel map for land near Waddington?
