Washington County, Pennsylvania
Washington County spreads south of Pittsburgh along I-79, with the city of Washington at its center, Canonsburg and Peters Township in the suburban north, and farmland beyond. Marcellus Shale operations and the Southpointe office market in Cecil Township drive nonresidential activity, while subdivision growth runs through Peters, North Strabane, and Cecil, so well pad setbacks, severed mineral rights, and school attendance zones govern site screening.
