Before an offer near Lennox, check the Tea flood map: a mapped flood zone changes insurance, permits and resale. What this Tea guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Lincoln County Beacon site.
Checking the Tea flood map step by step
The official source is FEMA's Flood Map Service Center: type an address near Sioux Falls, and choose the dynamic map. Vacant ground around Beresford can still be found: search the nearest road and click the spot.
Pulling up a parcel
Go first to the Lincoln County Beacon site; it covers each assessed parcel around Beresford and Worthing. Near Lennox, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For a home near Harrisburg, the record panel normally shows the owner of record, acreage on the tax roll, the parcel number and often a sale date.
Where Tea fits in
Tea sits in Lincoln County, South Dakota, which means parcel data comes from the county. Around Sioux Falls, the municipality handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the town limits toward Harrisburg often falls under county rules rather than the town's.
Reading the legal description
South Dakota is laid out under the Public Land Survey System, so rural legal descriptions near Beresford cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Worthing odd-sized. Write down the legal description for the tract near Beresford for any title or survey request.
Neighboring parcel maps
Lincoln County meets Lyon County, IA, Sioux County, IA, Clay County, Minnehaha County, and Turner County; every one of them runs a separate parcel map. Acreage along the edge near Sioux Falls can be split across two assessors' files, so open the adjacent map as well. In and around Lennox, our state page lists every neighboring county map for South Dakota.
A short flood checklist
Request about past flood claims for the house near Worthing; an insurance quote early keeps the budget honest.
Low spots and local drainage
Small streams around Lennox aren't always studied in detail, so walk the land after rain. Wet ground around Worthing is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
What the map can't tell you
Parcel lines are drawn for taxes, not surveyed, so the edge of a yard near Beresford can sit some distance off the line on screen. On ground around Lennox, records update in batches, so a deed recorded last month might lag behind.
Places you'll see on the map
Canton is the county seat, where most land records are kept. Other places on the map include Harrisburg, Sioux Falls, Lennox, and Worthing, each with its own cluster of lots. About 73,238 people live in Lincoln County (Census estimate, 2023) on roughly 577 square miles. Lincoln County was organized in 1867, and some chains of title near Worthing are long. Places such as Big Sioux River and Good Earth State Park make handy reference points on the map near Harrisburg.
Reading A, AE and X
An AE label comes with a base flood elevation, which plain A zones lack; surveyors near Worthing use that number. For a home near Sioux Falls, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so pair it with the Lincoln County Beacon site for the outline of the tract near Beresford.
What a flood zone means for a buyer
In and around Beresford, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. Building or adding on near Worthing in a mapped zone usually means extra permit review; check with the county or town building office before you plan.
Which office to call
Deeds, mortgages and recorded plats for land near Sioux Falls sit in the index kept by the Register of Deeds, usually searchable by name or document number. Building or septic questions for a lot near Sioux Falls are for the local planning and health departments, depending on whether the land is inside town limits.
Questions about the Tea flood map

Short answer: zones near Sioux Falls can shift when FEMA updates a panel, so look at the panel date.
How do I check the flood zone for an address in Tea?

When is flood insurance required around Beresford?
For most people, for a building near Worthing in an A or V zone with a federally backed or regulated mortgage, it's generally required; outside those zones it's your call.

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.
