Before an offer near Clover, pull up the Fort Mill flood zone map: a mapped flood zone changes insurance, permits and resale. In this Fort Mill guide: finding the address on FEMA's map, reading the zone codes, and pairing it with the York County ArcGIS parcel map.
Getting started with the Fort Mill flood zone map
The official source is FEMA's Flood Map Service Center: search an address around McConnells, and pick the FIRMette or map view. Rural land near Tega Cay with no street number is still easy to locate: zoom in from US Route 21 and click the spot.
Opening the official parcel viewer
Your first stop is the York County ArcGIS parcel map; it includes every assessed parcel around Clover and Rock Hill. When a rural tract has no street number, pan along US Route 21 and click the parcel itself. Around York, write down the parcel ID from that panel; each clerk in the county will want it.

Low-lying fields near Clover may not have detailed mapping, so ask neighbors about past flooding. Wetlands near Clover can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Before you lean on the lines
Acreage on the record is a tax-roll number; only a licensed surveyor establishes the real boundary on land around Rock Hill. For land near Hickory Grove, records update in batches, so a deed recorded last month might lag behind.
Fort Mill and the county around it
Fort Mill lies within York County, South Carolina, which means parcel data comes from the county.
