This seems to be a rather biased news report (not really an article). Why not also quote the increase in green space, and where the concentration of building space is located (infill between Agrodome and the Pacific Coliseum), or mention the high points of the master plan like the encircling cycle path, daylighting of Renfrew creek, etc? Playland was small to begin with, so 70% increase for year-round amusements isn't much.
Is Mr. Cadman really being as dismissive as he seems to disregard the years of public consultation and development by city staffers that have struck [what seems to me to be] a very good compromise between paved amenities vs. greening the whole thing? It seemed to me the public who participated in the consultation (including the residents in the surrounding neighbourhood) provided good feedback that was incorporated into the ultimate plan as proposed to council for ratification.
