Riverfronts and the region formerly known for steel
But the 1988 conference had other big impact pieces. Just one was the focused report on the Mon Valley. You can read the AIA's R/UDAP (Regional/Urban Design Assistance Team) report online here: Remaking the Mon Valley. Worth a read in itself. No time to truly decompile it here, but one hard to ignore truth is that a lot of the communities that report focused on: Braddock, Rankin, Homestead (if you look past the Waterfront of course) just to begin, are far worse off now than they were 25 years ago. They are all certainly much smaller having suffered nearly continuous population loss since then.
Truth is that the report was not super well received by the community it was supposed to be helping. Where the communities of the Mon Valley were still looking for a path to bring back manufacturing to the region, the message the AIA team provided was just a bit different. When responding to questions at a public meeting in the Mon Valley, one of the report's authors had this to say:
