Before an offer near Raymond, look at the Clark County flood zone map: a mapped flood zone changes insurance, permits and resale. In this county guide: the free FEMA tools, what each zone label means, lender insurance rules and what a LOMA is, at least around Crocker.
The Clark County flood zone map: start here
For parcel-by-parcel detail, open the National Flood Hazard Layer viewer, where zone shading sits over a photo base, whether the land is near Collins Colony or elsewhere in the county. Vacant ground around Fordham Colony is still easy to locate: zoom in from the nearest road then click the parcel area.
The viewer Clark County publishes
Go first to the Clark County parcel viewer; it maps each assessed parcel from Mayfield Colony to Collins Colony. For acreage around Vienna, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a parcel near Naples, copy the parcel ID before closing the panel; each office in the county will want it.
Water near Willow Lake
Low-lying fields near Vienna aren't always studied in detail, so walk the land after rain. Marshy spots near Fordham Colony can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Clark County in a few facts
Clark holds the county offices, where most land records are kept. You'll also find Willow Lake, Bradley, Garden City, and Naples, where town lots give way to larger tracts. Around 3,948 people call Clark County home (Census estimate, 2023) spread over about 958 square miles. The county was formed in 1873, which matters when you trace an old farm's title for land near Willow Lake.
Using it on a phone
The parcel map usually runs in a mobile browser, useful out on a road near Garden City, though signal can drop in rural spots. A screenshot of the parcel near Mayfield Colony with its ID helps when you meet an owner or agent.
Offices that can help
Anything recorded against property around Fordham Colony come from the Register of Deeds, usually searchable by name or document number. Questions about what you can build around Naples need the planning or permitting office, and the answer depends on jurisdiction.
Questions to ask before you buy
Ask the seller whether the home has flooded for the house near Collins Colony; getting a quote early keeps the budget honest.
Reading A, AE and X
For a parcel near Collins Colony, any A or V zone are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. If the land is near Hillcrest Colony, shaded Zone X is moderate risk, roughly the 100- to 500-year range; plain X, or C on older maps, means minimal mapped risk.
Where the recorded documents are
With a lot near Vienna, 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 tract near Garden City, bring the document number from the tax record so staff can find the deed fast.
Before you lean on the lines
For land near Raymond, the acreage figure is an estimate; just a licensed surveyor can set the real lines on the ground. Closer to Garden City, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so pair it with the Clark County parcel viewer to confirm you have the right parcel near Crocker.
Next door to Clark County
The county meets Beadle County, Codington County, Day County, Hamlin County, and Kingsbury County, all with their own assessor records around Crocker. Acreage along the edge near Crocker may show up in two county records, so look at the adjacent map as well. For acreage around Mayfield Colony, our state page links each neighboring county map for South Dakota.
Money questions tied to the zone
For a home near Crocker, get the Elevation Certificate if one exists: it can change the insurance price a lot. New construction in a floodplain near Naples can trigger elevation rules; call the permitting office early.
Reading the legal description
South Dakota uses the Public Land Survey System, so rural legal descriptions near Mayfield Colony cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Willow Lake vary in size. Copy the legal description from the record for the parcel near Mayfield Colony when you talk to a surveyor.
Frequently asked
What is a base flood elevation around Collins Colony?
Generally, a BFE near Crocker tells builders how high the lowest floor should be; local rules may require building above it.
What is the difference between Zone A and AE near Vienna?
If the land is near Mayfield Colony, an AE zone has a 1% annual chance of flooding and a base flood elevation; unnumbered A zones don't list one.
Is Zone X safe from flooding for land near Mayfield Colony?
Generally, Zone X near Raymond means moderate (shaded) or minimal (unshaded) mapped risk, and floods still happen outside high-risk zones.
Is there a flood layer on the parcel viewer near Collins Colony?
It depends, but the parcel map near Collins Colony might show FEMA zones, but FEMA's own map is the official source.
Can I settle a boundary dispute with the map near Collins Colony?
For acreage around Willow Lake, parcel lines are tax drawings, not surveys; a survey sets the real corners

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.
