Petitions count for nothing. Submit an objection. They are pretty useless as well. The Land and Environment Court is the wedge the government relies upon to open up Low Density Residential Zones to massive commercial development. Once the first shambolic court decision is created the following 'around the corner' developments sail though with relative ease. The fallacy that local amenity and resident concerns are important criteria is a joke and well documented in L&E Court judgements. They are hollow words used to pad out Local Development Control Plans. There is no town planning in established residential areas. It's a developer's free for all.
This development is the equivalent of 25 more town houses in a narrow over developed residential street which already experiences major traffic problems each morning. Best of luck because authority is not on our side. I did a letterbox drop in Margaret Street some years ago concerning the proposed CCC at 32 Mary Street; I don't suppose Margaret Street objected back then. Good luck this time if you are a fellow objector.
