Collin County, Texas
Collin County anchors Dallas–Fort Worth's northern growth corridor, with Plano, Frisco and McKinney forming one of the country's strongest corporate-relocation markets. Development is racing north along US 380 and the Dallas North Tollway into Prosper and Celina, where new master-planned communities and school-district boundaries drive most siting decisions.
