I really don't blame local residents for being concerned about this kind of density given how vague the proponents are being about what the proposal will look like. Density at this level warrants very careful design (along the lines of the Christie site and Lakeview Village). For comparison, the Christie site is 28 acres and 7500 units, which is 681 units per hectare but it is located between a future electrified GO station and a streetcar line. A development at 350 units/hectare with just a bus stop is concerning. It is 2 km from Long Branch GO. Even if we're to add an infill GO station at Cawthra to serve the densifying area between Port Credit and Long Branch, this site would still be 2 km from the station.
All that's to say, I'm not sure this is the right site for this kind of density. It is going to tend to be quite car oriented. Maybe if Line 2 were extended to Sherway and on toward this site
