PUDI've thrown away the paper now. I was holding on to it for a proposed paper until I hit the "paper that was supposed to write itself." But the tossed paper was testimony or a chapter of an academic piece located in the Zoning Files for the National Capital and Planning Commission on the problem with PUDs. A PUD is a Planned Unit Development, usually for something taking up a lot of space, like 1/2 a block or more. On ANC Kevin Chapple's site there is more information about the PUD for the O Street Market.
What I remember from going through the different PUDs filed from the late 1980s to the 1990s, is that the longer these things drag out, some concessions get lost in the process and the PUDs kept reappearing as something new as changes (due to something...engineering/ community wants/ government fickleness) were applied. If the O Street Market project stays on schedule and no other stakeholders or late comers add anything, then all should be well.
