Before you buy or build near Henry, look at the Watertown flood zone map: a mapped flood zone changes insurance, permits and resale. In this Watertown guide: locating a parcel on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
Where the Watertown flood zone map lives
The official source is FEMA's Flood Map Service Center: search an address around Florence, then open the map view for that panel. Rural land near South Shore with no street number can still be found: pan from the closest town and click inside the land.
Pulling up a parcel
Go first to the Codington County parcel viewer; it includes each tax parcel in the county, Florence included. On ground around South Shore, type a street address, an owner's name or a parcel number, and the matching parcel lights up. If the land is near Henry, the record panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
Next door to Codington County
Codington County touches Clark County, Day County, Deuel County, Grant County, and Hamlin County, and each of those keeps its own parcel map. Ground near Wallace that runs to the line can be split in two county records, so check the adjacent map too. Around Wallace, the Platbookmapper state page lists each neighboring county map across South Dakota.
Low spots and local drainage
Small streams around South Shore aren't always studied in detail, so look for water marks and debris lines. Marshy spots near South Shore can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Where Watertown fits in
Watertown is part of Codington County, South Dakota, which means parcel data comes from the county. Watertown is also the county seat, so deeds and plats are filed in town. Around Florence, the municipality handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the town limits out by Kranzburg usually falls under county rules rather than the town's.
Offices that can help
Questions about value or the owner field for land near Kranzburg go to the Director of Equalization, the office behind the parcel record. Building or septic questions for a lot near Henry go to planning, building or health offices, depending on whether the land is inside town limits.
What to request from a seller
Ask the seller about past flood claims for the house near Wallace; getting a quote early keeps the budget honest.
The paper trail behind a parcel
When the details count, pull the recorded deed through the Register of Deeds; the parcel map near Florence only summarizes it. Inherited tracts near South Shore can go back through a long string of deeds, so a title company is worth hiring on a real sale.
On site with the map
Most viewers work in a phone browser, useful out on a road near Wallace, so load it before you lose signal. A screenshot of the parcel near Wallace with its ID helps when you meet an owner or agent.
Zones on the Watertown flood zone map
Out toward Henry, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. If the land is near South Shore, 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.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so pair it with the Codington County parcel viewer for the outline of the tract near Henry.
Places you'll see on the map
Watertown is the county seat, home to the main records offices. You'll also find Kranzburg, Florence, Henry, and South Shore, where town lots give way to larger tracts. Roughly 28,971 people call Codington County home (Census estimate, 2023) on some 688 square miles. Features like Pelican Lake Recreation Area make handy reference points on the map near Henry.
What a flood zone means for a buyer
With a lot near Henry, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. Remodeling a house in a zone near Wallace often needs a floodplain permit; call the permitting office before you plan.
Questions about the Watertown flood zone map
What is a base flood elevation for land near Florence?
Short answer: a BFE near Kranzburg tells builders how high the lowest floor should be, and an Elevation Certificate compares the building to it.
What if the flood map is wrong for my lot near Kranzburg?
Good question; FEMA's LOMA process is the usual route when a building near Wallace sits above the base flood elevation; a surveyor's elevation data supports it.
Do I need to worry about flooding in Zone X around South Shore?
It depends, but X zones around Henry are lower risk, not no risk; many owners near Wallace buy coverage anyway.
How often are flood maps updated around Henry?
For most people, zones near Kranzburg can shift when FEMA updates a panel, so look at the panel date.
What's the tax parcel number used for in Watertown?
The parcel ID identifies one tax parcel near Florence, and it's on the record panel and tax bills.
