Allegheny County, Pennsylvania
Allegheny County surrounds Pittsburgh, which sits where the Allegheny and Monongahela rivers meet to form the Ohio, and spreads across 130 separate municipalities of mill towns, streetcar suburbs and river valleys. Health care, universities and robotics carry the economy, while new industrial space concentrates near Pittsburgh International Airport and on steel-era brownfields such as Hazelwood Green; zoning differs at every municipal line.
