Before you buy or build near Columbia, pull up the Cayce flood zone map: a mapped flood zone changes insurance, building rules and resale. In this Cayce guide: locating a parcel on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
Getting started with the Cayce flood zone map
Flood zones come from FEMA's Flood Map Service Center: search an address around Irmo, and pick the FIRMette or map view. Rural land near Columbia with no street number can still be found: zoom in from the nearest road then click the parcel area.
Getting to the right map
Go first to the Richland County parcel viewer; it maps every tax parcel around Columbia and Blythewood. For property near Blythewood, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a tract near Arcadia Lakes, the record panel typically gives the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
What to request from a seller
Ask the listing agent whether the home has flooded for the house near Forest Acres; getting a quote early keeps the budget honest.
City limits and county records
Cayce lies within Richland County, South Carolina, so its parcels are on the county's map. For land near Forest Acres, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Acreage past the city limits out by Eastover usually follows county rules rather than the town's.
Deeds, plats and who keeps them
For anything that matters, pull the recorded deed from the Register of Deeds (in some counties the Clerk of Court); the parcel map near Irmo only summarizes it. Long-held tracts around Eastover can go back through several deeds, so a title company earns its fee before a purchase.
What the map can't tell you
Listed acreage is a tax-roll number; only a licensed surveyor establishes the real lines for a parcel near Irmo. On ground around Columbia, records update in batches, so a deed recorded last month can take weeks to appear.
Offices that can help
Anything recorded against property around Arcadia Lakes are with the Register of Deeds (in some counties the Clerk of Court), usually searchable by name or document number. Questions about what you can build around Irmo are for the local planning and health departments, town or county, depending on location.
A quick look at the area
Columbia is the county seat, home to the main records offices. You'll also find Forest Acres, Arcadia Lakes, and Irmo, each with its own cluster of lots. About 425,138 people call Richland County home (Census Bureau estimate, 2023) on some 757 square miles. Richland County was formed in 1785, so old deeds can run back a long way. Places such as Congaree National Park are easy to spot when you zoom out from Columbia.
Zones on the Cayce flood zone map
An AE label comes with a base flood elevation, and an unnumbered A zone has none; that elevation drives building rules near Forest Acres. Around Eastover, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Sections, lots and bearings
Tracts outside towns near Arcadia Lakes are often described by metes and bounds, listing bearings, distances and landmarks. Subdivision lots in Blythewood are typically described by lot and block, making them easier to find. Write down the legal description for the tract near Eastover for any title or survey request.
Field tips
Most viewers work in a phone browser, useful out on a road near Forest Acres, so load it before you lose signal. A screenshot of the parcel near Arcadia Lakes with its ID is a good backup.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so check the Richland County parcel viewer too for the outline of the tract near Irmo.
What a flood zone means for a buyer
In and around Blythewood, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. Remodeling a house in a zone near Forest Acres can trigger elevation rules; call the permitting office early.
Water near Blythewood
Creeks and ditches near Arcadia Lakes aren't always studied in detail, so walk the land after rain. Wetlands near Columbia can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
