John Murray's piece is based on his role chairing the Committee to Prepare Allegheny County for the 21st Century (otherwise known as COMPAC 21) which I have here:
COMPAC21 - Preparing Allegheny County for the 21st Century. A Report to the Allegheny County Board of Commissioners by the Committee to Prepare Allegheny County for the 21st Century. January 1996
To understand COMPAC 21, here are just a few other documents that you have to read along with it to understand how it evolved in local politics:
