Blair County, Pennsylvania
Blair County sits in the Allegheny Front of central Pennsylvania, anchored by Altoona and the county seat of Hollidaysburg, with ridge-and-valley terrain between them. Rail heritage, healthcare, and manufacturing carry the economy, while retail and housing growth concentrates in Logan Township along the Plank Road corridor and the I-99 interchanges, so buildable valley floor, zoning lines, and enterprise-zone boundaries determine what a site can become.
