Ahead of any purchase around Avon, check the Bon Homme County flood map: a mapped flood zone changes insurance, permits and resale. Covered here for Bon Homme County: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the District III regional GIS map.
Getting started with the Bon Homme County flood map
For a home near Tyndall, start with FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. A tract near Springfield Recreation Area without an address is still easy to locate: pan from the closest town and click inside the land.
The viewer Bon Homme County publishes
Go first to the District III regional GIS map; it includes every assessed parcel around Tyndall and Missouri National Recreational River. For acreage around Running Water, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For acreage around Running Water, save the parcel ID while you have it open; every records desk in the county asks for it first.
What the zone letters mean
Zone AE includes a base flood elevation (BFE), and an unnumbered A zone has none; builders around Scotland design to it. For property near Springfield Recreation Area, a low-risk label isn't a guarantee: according to FEMA, many claims come from moderate- and low-risk areas.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Missouri National Recreational River, so load it before you lose signal. A saved image of the lot near Scotland and its lines helps when you meet an owner or agent.
Before you lean on the lines
Parcel lines are drawn for taxes, not surveyed, so the edge of a yard near Missouri National Recreational River often sits a few yards off the line on screen. Out toward Avon, records update in batches, so a deed recorded last month can take weeks to appear.
Places you'll see on the map
Tyndall holds the county offices, where most land records are kept. You'll also find Avon, Scotland, Springfield, and Tabor. About 7,065 people live in Bon Homme County (Census estimate, 2023) on roughly 564 square miles. Bon Homme County was organized in 1862, so old deeds can run back a long way. Landmarks such as Missouri River, Missouri National Recreational River, and Springfield Recreation Area help you orient on the aerial.
Reading the legal description
South Dakota follows the Public Land Survey System, which means a tract near Missouri National Recreational River 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 corrections make some sections near Running Water odd-sized. Copy the legal description from the record for the parcel near Springfield for any title or survey request.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so open the District III regional GIS map next to see exactly which lot near Running Water you're looking at.
Getting answers from the right desk
If the acreage or value on a parcel near Tyndall looks off are handled by the Director of Equalization, since that office keeps the assessment data. Questions about what you can build around Running Water are for the local planning and health departments, and the answer depends on jurisdiction.
What a flood zone means for a buyer
For property near Springfield Recreation Area, get the Elevation Certificate if one exists: it can change the insurance price a lot. New construction in a floodplain near Scotland usually means extra permit review; ask the local floodplain administrator early.
Backing up the map with records
When the details count, get the recorded deed through the Register of Deeds; the parcel line is a drawing of it, whether the land is near Tabor or elsewhere in the county. For land near Springfield Recreation Area, use the book and page listed on the parcel record and the lookup takes minutes.
Water near Tabor
Low-lying fields near Missouri National Recreational River may not have detailed mapping, so ask neighbors about past flooding. Marshy spots near Bon Homme Colony can limit building too; check the National Wetlands Inventory mapper for a first look.
What to request from a seller
