As a former resident of Commercial Drive, I support the move to further develop the immediate Commercial-Broadway area as a higher-density mixed-use node. While I am hesitant to see the floodgates of change open up on my old neighbourhood, I do think that there is a place for modestly tall, architecturally significant towers in the 20 to 30 storey range at the Safeway site, including a substantial office and retail component. You don't need towers for residential and employment density, but that specific site and its adjacency to SkyTrain warrant a Marine Gateway-like (or Woodwards-like) residential and office development, a low-income housing component, and potentially as a satellite campus for a post-secondary institution or career college.
A variety of rental and condo mid-rise buildings (of which there are already a large number west of Commercial Drive) off of the main streets and standard arterial C2 buildings south of Broadway) would gently add additional residents, especially for those priced out of other central neighbourhoods. I think that somewhat taller mid-rise buildings (think SEFC) buildings in the immediate vicinity of the station and along Broadway would also be appropriate, and ideally would include substantial employment space. Commercial Drive itself between the Grandview Cut and Venables should remain largely unchanged from a built form perspective as it is working well and the low-rise buildings generally offer good sunlight access to the sidewalks. Additional mid-rise development with retail at grade should fix the gap between Venables and Hastings and connect up there with the expanding Hastings neighbourhood retail corridor that currently peters out around Victoria.
The neighbourhood as a whole already has a lot of overt gentle density (low- and mid-rise apartment buildings, duplexes on formerly single family lots, townhouses, and mixed-use buildings with apartments above shops) as well as substantial hidden density (shared apartments and houses, basement and attic suites), so this isn't a case of a low density area adjacent to SkyTrain, such as the case around Nanaimo or 29th Avenue station.
It's also worth noting that there are already a few towers in the neighbourhood, though they are certainly not of the same scale as those contemplated for the SkyTrain Station area.
