It's clear that the traditional Downtown core alone will not be able to accommodate much more in the way of people or businesses: the inventory of vacant or underutilized land within the downtown neighbourhood has dimished to a level that will simply not meet future demand.
What do y'all think of that? Off the top of my head:
Wharf street parking lots;
Capital Iron parking lot;
Rock Bay parking lots, empty lots, and underutilized lots;
parking lots around the legislature;
flatiron parking lot;
Janion parking lot;
Chinatown parking lots;
Radius site;
Centro site;
underutilized lots at Blanshard/Caledonia;
Traveller's Inns and parking lots;
Gateway Green site;
Johnson Street parkade;
Johnson Street parking lots between Blanshard and Cook;
car dealership lots around Yates and Cook;
parking lots and empty lots around View Towers;
empty lot at View Street and Vancouver Street;
Capitol 6 and parking lot;
Broughton Street parking lots between Douglas and Quadra;
Courtney Street parking lot and underdeveloped lots;
Royal Theatre parking lot;
Courthouse underdeveloped lot;
Bus station underdeveloped lot;
Crystal Court motel underdeveloped lot;
St. Andrew's Presbyterian gymnasium underdeveloped lot;
di Castri storefronts underdeveloped lot;
Yates Street swamp lot;
Pandora and Quadra strip mall;
Johnson and Vancouver strip mall;
Underdeveloped office building on Blanshard behind Centro lot;
The number of significant office buildings and residential buildings that you could build on those lots would well exceed the number of significant office buildings and residential buildings that already exist.
