Ahead of any purchase around Afton, check the Woodbury flood zone map: FEMA's zone label affects insurance, building rules and resale. What this Woodbury guide covers: finding the address on FEMA's map, reading the zone codes, and matching it with the county parcel viewer.
Where the Woodbury flood zone map lives
The official source is FEMA's Flood Map Service Center: search an address around Afton, and pick the FIRMette or map view. A tract near Newport without an address is still easy to locate: pan from the closest town and click inside the land.
The free map to start with
Your first stop is the Washington County ArcGIS parcel map; it includes every tax parcel in the county, Newport included. Without an address in hand, zoom in from Cottage Grove and select the outline. For a home near Landfall, the parcel card typically gives the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Places you'll see on the map
Stillwater serves as the county seat, where most land records are kept. Other places on the map include Landfall, Newport, Afton, and Lake Elmo, where town lots give way to larger tracts. Roughly 278,936 people call Washington County home (Census Bureau estimate, 2023) spread over roughly 385 square miles. Washington County was organized in 1849, and some chains of title near Lake Elmo are long. Features like Afton State Park help you orient on the aerial around Landfall.
Low spots and local drainage
Small streams around Lake Elmo may not have detailed mapping, so walk the land after rain. Wetlands near Afton can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Who handles what
Recorded documents for a parcel near Newport come from the County Recorder, usually searchable by name or document number. Zoning, permits and septic questions near Newport go to planning, building or health offices, depending on whether the land is inside town limits.
City limits and county records
Woodbury is part of Washington County, Minnesota, which means parcel data comes from the county. In and around Afton, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Acreage past the town limits toward Newport generally answers to county rules, not municipal ones.
What the zone letters mean
Zone AE includes a base flood elevation (BFE), which plain A zones lack; surveyors near Cottage Grove use that number. Out toward Newport, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
When a parcel crosses a boundary
Washington County touches Anoka County, Chisago County, Dakota County, Ramsey County, and Pierce County, WI, all with their own assessor records. A tract near the line by Oakdale can show up in two county records, so check the adjacent map too. For land near Newport, our state page links every neighboring county map for Minnesota.
Taking the map into the field
Most viewers work in a phone browser, which helps when you're standing on land near Oakdale, so load it before you lose signal. A saved image of the lot near Landfall and its lines is a good backup.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so check the Washington County ArcGIS parcel map too for the outline of the tract near Landfall.
A short flood checklist
Request for any Elevation Certificate for the house near Landfall; an insurance quote early avoids surprises.
Lenders and permits
For property near Landfall, get the Elevation Certificate if one exists: it compares the building to the BFE. Building or adding on near Landfall in a mapped zone often needs a floodplain permit; check with the county or town building office early.
Deeds, plats and who keeps them
For anything that matters, request the recorded deed through the County Recorder; the parcel map near Lake Elmo only summarizes it. Older tracts near Landfall may go back through many deeds, and a title company earns its fee if money is changing hands.
Limits of the parcel data
Parcel lines are drawn for taxes, not surveyed, so a fence near Landfall may sit some distance off the line on screen. For acreage around Afton, records update in batches, so a deed recorded last month might lag behind.
