Here's why - from the website under Architecture - siteplan - there's retail with parking.
There is existing surface parking on the adjacent property for Inn at the Quay, and the office building -
that adjacent parking also looks to be elevated a few feet versus the RiverSky site.
On the Site plan - based on the small square (ventilation shaft?) at 10th St,
it looks like all the parking shown on the siteplan is existing parking and RiverSky will abut that parking area with a walkway and retail stores.
Also, note the driveway directly from McInnes Overpass.
