Weighing a property around Dellwood? Checking the Hugo flood zone map reveals whether the lot falls inside a mapped floodplain, and no account is needed. In this Hugo guide: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Washington County ArcGIS parcel map.
Getting started with the Hugo flood zone map
Start with FEMA's Flood Map Service Center: type an address near Birchwood Village, and choose the dynamic map. A tract near Dellwood without an address is still easy to locate: zoom in from Interstate 494 and click the spot.
Pulling up a parcel
Your first stop is the Washington County ArcGIS parcel map; it covers every tax parcel from White Bear Lake to Grant. With a lot near Dellwood, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a home near Birchwood Village, the record panel usually lists the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
Sections, lots and bearings
Minnesota follows the Public Land Survey System, which means a tract near Mahtomedi is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Forest Lake can be irregular. Keep the legal description for land near Mahtomedi before you request a deed or survey.
Which office to call
Deeds, mortgages and recorded plats for land near Mahtomedi sit in the index kept by the County Recorder, often with an online index. Zoning, permits and septic questions near Forest Lake are for the local planning and health departments, town or county, depending on location.
A short flood checklist
Ask the seller whether the home has flooded for the house near White Bear Lake; getting a quote early avoids surprises.
Beyond the mapped zones
Low-lying fields near White Bear Lake may not have detailed mapping, so look for water marks and debris lines. Marshy spots near White Bear Lake can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
City limits and county records
Hugo is part of Washington County, Minnesota, so its parcels are on the county's map. In and around Mahtomedi, city or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the city limits out by Grant often falls under county rules, not municipal ones.
Reading A, AE and X
On ground around Grant, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For a tract near Dellwood, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so open the Washington County ArcGIS parcel map next to confirm you have the right parcel near Mahtomedi.
Recorded documents worth pulling
Before you sign anything, pull the recorded deed through the County Recorder; the parcel map near White Bear Lake only summarizes it. Inherited tracts around White Bear Lake may go back through many deeds, and a title company can sort it out before a purchase.
Lenders and permits
If you're looking near White Bear Lake, ask for an Elevation Certificate: it records the building's elevation against the base flood. New construction in a floodplain near Mahtomedi can trigger elevation rules; check with the county or town building office early.
Before you lean on the lines
Acreage on the record is a tax-roll number; only a licensed surveyor sets the real corners on land around Forest Lake. For property near Dellwood, records update in batches, so a deed recorded last month might lag behind.
Next door to Washington County
Washington County borders Anoka County, Chisago County, Dakota County, Ramsey County, and Pierce County, WI, all with their own assessor records. A tract near the line by Dellwood may be split in two county records, so check the adjacent map as well. In and around Grant, the Platbookmapper state page lists every bordering county map across Minnesota.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Dellwood, so load it before you lose signal. A saved image of the lot near White Bear Lake and its lines keeps working without signal.
Quick answers
Why did my flood zone near Birchwood Village change?
It depends, but a new study can move a zone line near Birchwood Village, so look at the panel date.
Does the county parcel map show flood zones near Forest Lake?
Good question; a flood layer may appear in the Washington County ArcGIS parcel map layer list, but FEMA's own map is the official source.
What if the flood map is wrong for my lot near White Bear Lake?
You can ask FEMA for a LOMA if surveyed elevations show the building near Birchwood Village is above the BFE; a surveyor's elevation data supports it.
What does an AE label mean for a lot near White Bear Lake?
Both are high-risk zones, but only AE has a base flood elevation, so builders near White Bear Lake design to that elevation.
What's the tax parcel number used for in Hugo?
It's the number the County Assessor uses to track a tract near Mahtomedi; you'll see it in the viewer and on tax statements.

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.
