Both Rupert Dance over at Plantastic and Designerific and Alan Davies at The Urbanist weighed in with good posts on Matthew Guy’s mooted mega-CBD. This got a big run in the Herald Sun first thing on the Friday before last, followed by a catch-up story later the same day by The Age. (The Herald Sun were obviously fed the scoop: perhaps The Age is being punished for its vigorous pursuit of Guy over the Ventnor rezoning).
Guy’s press release is here, and the map is reproduced below (click to see the original PDF). Oddly, there’s no explanation that I can find for the yellow blobs, though we can infer from their location that they’re industrial precincts. The DPCD website carried an almost comically non-committal story essentially just saying “Matthew Guy said some stuff: here’s a link,” so we can’t look to them for clarification.
