Actually Pittsburgh’s Hill District WAS the inspiration for Hill Street Blues. Steven Bochco graduated from Carnegie Tech (now Carnegie-Mellon Univ.) in 1966.

Wasn't the TV series actually filmed in Pittsburgh even though it was supposedly based in Philadelphia?

Loved that series! We moved to the 'burgh area many years later, but so much of that background looks familiar, right down to the potholes in the streets.
