Its parking program already in flux, the city of Vancouver is preparing for what could be the biggest curve ball yet: the Columbia River Crossing.The $3.5 billion project would put three park-and-ride facilities in Vancouver to accommodate light rail, one of them near the heart of downtown. It’s assumed C-Tran would own the garages, not the city.The challenge? As plans currently stand, those three facilities would add 2,900 free spaces to a municipal system that now expects users to pay for parking. The change could further squeeze a program that’s losing money as officials work to reshape it.“It would have a direct impact on the city’s parking program, absolutely,” said Mike Merrill, the city’s parking services manager. “It’s hard to say at this point what the impact will be, but it definitely will have some impact.”The city’s parking system lost $1.97 million in 2011, a loss driven mostly by debt payments on city-owned facilities. The largest of those, the 750-space Vancouvercenter garage, accounted for the lion’s share of that loss.
