GROWTH AND PUBLIC SERVICES
Greenville County has experienced enormous growth in recent years. In just the past ten years Greenville County (not including the six cities) has approved 375 separate subdivision projects. Greenville County Long Range Planning records 24,194 lots on 11,447 acres across those projects, a little over 2% of the county, counting 2026 through June only. Cost of Community Services studies compiled by the American Farmland Trust found a median $1.16 in public-service costs for every $1 of residential revenue in the communities studied. These studies describe existing land uses, not the costs of future growth. Comparable local data for Greenville County is not available.
