9 stories is acceptable at that location IMO. I would be surprised if there as much opposition to it....pending the design of course. IIRC residents weren't crazy about Pixel. @Nimbus probably remembers that better than I do.
I recall the developer had shown the concept to the community. Does anyone what the feedback was?
According to the hillhirst Sunnyside ca meeting minutes (on a tablet in Cabo so can't provide a link, just Google the website) Graywood is planning 9 stories with retail at grade for the RBC site. Just a verbal description, no massing.
