Weighing a property around Nowlin? Checking the Haakon County flood zone map reveals whether the lot falls inside a mapped floodplain, and it costs nothing to check. In this Haakon County guide: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the District III regional GIS map.
Getting started with the Haakon County flood zone map
For parcel-by-parcel detail, try the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, for land near Milesville included. A tract near Midland without an address can still be found: pan from the closest town then click the parcel area.
The free map to start with
Parcels around Philip appear on the District III regional GIS map, which opens without registering. Closer to Midland, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For land near Midland, copy the parcel ID while you have it open; every clerk in the county will want it.
Zones on the Haakon County flood zone map
For acreage around Midland, A and V zones mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. If the land is near Milesville, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Water near Nowlin
Low-lying fields near Nowlin aren't always studied in detail, so walk the land after rain. Marshy spots near Philip can limit building too; check the National Wetlands Inventory mapper for a first look.
Next door to Haakon County
Haakon County touches Dewey County, Jackson County, Jones County, Meade County, and Pennington County, and each of those keeps its own parcel map. A tract near the line by Nowlin may be split in two county records, so check the neighboring map too. For a parcel near Milesville, the Platbookmapper state page lists each bordering county map for South Dakota.
Places you'll see on the map
Philip serves as the county seat, where most land records are kept. Other places on the map include Midland, Milesville, and Nowlin. Around 1,851 people live in Haakon County (Census estimate, 2023) across about 1,811 square miles.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so check the District III regional GIS map too to confirm you have the right parcel near Midland.
Insurance, lenders and building
In and around Nowlin, an Elevation Certificate from a surveyor helps: it compares the building to the BFE. Remodeling a house in a zone near Midland can trigger elevation rules; check with the county or town building office before you plan.
What the map can't tell you
For a home near Midland, listed acreage is an assessed number; only a licensed surveyor establishes the real corners on the ground. Out toward Nowlin, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Milesville, so load it before you lose signal. A printout of the tract near Midland keeps working without signal.
Reading the legal description
South Dakota follows the Public Land Survey System, which means a tract near Philip is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Milesville vary in size. Write down the legal description for the tract near Nowlin for any title or survey request.
The paper trail behind a parcel
If the land is near Milesville, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county are kept by the Register of Deeds. For a home near Philip, inherited tracts in the county can sit on several deeds, so a title company is worth hiring before a purchase.
A short flood checklist
On ground around Milesville, ask the seller whether the home has flooded before closing; an insurance quote early avoids surprises.
Getting answers from the right desk
If the acreage or value on a parcel near Midland looks off are handled by the Director of Equalization, since that office keeps the assessment data. Questions about what you can build around Nowlin need the planning or permitting office, depending on whether the land is inside town limits.
Frequently asked
Do I need to worry about flooding in Zone X near Philip?
It depends, but Zone X near Philip means moderate (shaded) or minimal (unshaded) mapped risk; FEMA notes that a large share of claims come from these areas.
What is the difference between Zone A and AE around Midland?
Closer to Milesville, AE is a Special Flood Hazard Area with a published base flood elevation; unnumbered A zones don't list one.
Can a flood zone near Midland change?
Good question; a new study can move a zone line near Nowlin, so look at the panel date.
When is flood insurance required near Nowlin?
It depends, but lenders generally require it for buildings near Milesville in a Special Flood Hazard Area when the loan is federally regulated or insured, in communities that take part in the NFIP.
Why don't the lines match my fence near Milesville?
For a home near Philip, parcel lines are tax drawings, not surveys.

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.
