I suspect the city knows it has a problem with parking for the events centre, but is purposely downplaying the issue because they can't afford to do anything about it!!
The centre itself is costing $110M or so. The city also has to plan for a new police station (purportedly $40M) and has also made a commitment for a new north end community centre (likely another $10-15M). That's a total of $170M or so of new expenditures for the city. In other words - the cupboard is bare!!!
For the foreseeable future, the only way we are going to see a new parking structure in the core is if it is privately financed. This is regrettable because I strongly believe that parking structures would kickstart the redevelopment of all the surface parking lots in the core.
This is how a plan could be developed to end surface parking in the core:
1) - The city builds a couple of moderate to large parking structures in the core.
2) - This will reduce the demand for surface parking.
3) - The city should then develop a new tax regime increasing the property taxes on all properties in the downtown core used solely for surface parking.
4) - This will make it more expensive to maintain the surface parking lots and the parking rates on these surface lots will therefore have to go up.
5) - As parking rates go up, the new parking garages will become attractive alternatives for downtown workers.
6) - Usage of the downtown surface lots will begin to go down. As usage goes down, the surface lots become unprofitable.
7) - The owners of the surface lots will therefore have to come up with alternate uses for their downtown lands in order to remain profitable and to be able to pay their property taxes.
8) - Surface lots will disappear as they are sold or repurposed for condos, downtown public housing and commercial uses.
9) - The downtown suddenly becomes livable rather than a barren wasteland (at least south of Main).
This plan is a bit Machiavellian yes, but is simple and effective and really only requires two actions on the part of the city.
1) - Build the parking structures
2) - increase the tax rate on surface parking lots.
Everything else would happen organically.
