Butler County, Pennsylvania
Butler County covers the northern edge of metropolitan Pittsburgh, pairing fast-growing suburbs around Cranberry Township and Mars with the older industrial city of Butler and farmland north of it. Growth concentrates along the Route 228 and I-79 corridors, where retail, apartments and office space keep absorbing land, so sewer service boundaries, township zoning and Seneca Valley and Mars school attendance lines decide which parcels pencil.
