Thinking about a house near Deer Park? A quick look at the New Richmond flood zone map shows whether FEMA puts it in a high-risk zone, and the lookup is free. What this New Richmond guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the St. Croix County Beacon site.
Getting started with the New Richmond flood zone map
Start with FEMA's Flood Map Service Center: type an address near Deer Park, then open the map view for that panel. Rural land near Roberts with no street number is still easy to locate: pan from the closest town and click inside the land.
The free map to start with
Go first to the St. Croix County Beacon site; it maps each assessed parcel from Deer Park to Somerset. When a rural tract has no street number, pan along the nearest road until the lines appear, then click inside the one you want, and that holds around Deer Park too. Out toward Roberts, the parcel card normally shows the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
New Richmond and the county around it
New Richmond is part of St. Croix County, Wisconsin, so its parcels are on the county's map. Out toward Somerset, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Acreage past the town limits near Roberts often follows county rules rather than the town's.
Limits of the parcel data
The acreage figure is a tax-roll number; only a licensed surveyor can set the real boundary for a parcel near Roberts. With a lot near Deer Park, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Questions to ask before you buy
Ask the listing agent for any Elevation Certificate for the house near Star Prairie; an insurance quote early keeps the budget honest.
Next door to St. Croix County
St. Croix County touches Washington County, MN, Barron County, Dunn County, Pierce County, and Polk County, all with their own assessor records. A tract near the line by Roberts may be split across two assessors' files, so open the neighboring map too. Closer to Deer Park, our state page links every neighboring county map across Wisconsin.
Places you'll see on the map
Hudson serves as the county seat, home to the main records offices. Other places on the map include Star Prairie, Somerset, Deer Park, and Roberts. About 96,763 people live in St. Croix County (Census estimate, 2023) across roughly 722 square miles. St. Croix County was formed in 1849, so old deeds can run back a long way.
Low spots and local drainage
Creeks and ditches near Hammond may not have detailed mapping, so look for water marks and debris lines. Marshy spots near North Hudson can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Who handles what
Questions about value or the owner field for land near Hammond belong with the county real property listing office, the office behind the parcel record. Zoning, permits and septic questions near Star Prairie are for the local planning and health departments, depending on whether the land is inside town limits.
What the zone letters mean
An AE label carries a published BFE, while plain Zone A does not; surveyors near North Hudson use that number. In and around Roberts, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, means minimal mapped risk.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so open the St. Croix County Beacon site next for the outline of the tract near Star Prairie.
How land is described here
Wisconsin follows the Public Land Survey System, which means a tract near Deer Park is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near North Hudson odd-sized. Copy the legal description from the record for the parcel near Star Prairie for any title or survey request.
Money questions tied to the zone
For a parcel near Hammond, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. Building or adding on near Deer Park in a mapped zone often needs a floodplain permit; check with the county or town building office early.
New Richmond: common questions
Can a property in Zone X near Deer Park flood?
Good question; shaded X is moderate risk and unshaded X is minimal risk; many owners near Deer Park buy coverage anyway.
What is a LOMA in New Richmond?
For most people, FEMA's LOMA process is the usual route when a building near North Hudson sits above the base flood elevation; a surveyor's elevation data supports it.
What is a base flood elevation in New Richmond?
Usually, the base flood elevation is the water level expected in the 1% annual chance flood; surveyors near Hammond use it often.
Can a flood zone near Somerset change?
It depends, but zones near Hammond can shift when FEMA updates a panel, so look at the panel date.
Does the parcel map work on a phone for land near North Hudson?
No app is needed for most county viewers; load it before you lose coverage near North Hudson.
