Chester County, Pennsylvania
Chester County forms the western edge of suburban Philadelphia, stretching from the Main Line at Tredyffrin and Malvern through West Chester and Exton to the mushroom farms around Kennett Square. Pharmaceutical and life-science employment along the Route 202 and Route 30 corridors drives demand, while the county's Landscapes3 plan channels growth into designated growth areas and preserved farmland limits what is developable elsewhere.
