walking? probably quicker than driving
i don't think its even possible to drive to that station without going way up the hill to at least 8th or 10th or something and than turnng left against the traffic and finding your way to the station
there is a plan to have a pedestrian bridge connecting to new west quay so walking from this development to new west station shouldn't take much time at all 10 -15 mins walking
there is also ideas of connecting it with little ferries like false creek connecting sapperton, the quay and i assume surrey somewhere
