That whole area needs to be redeveloped into midrises 4-8 stories high and maybe an odd highrise cluster if the city and neighborhood will allow it. Same thing along the east side of Sunnyside station. Just that extra density boost would help the mainstreets become vibrant year around. It really is surprising how little density there is near our downtown core along the river. Most mid-large size metros have neighborhoods that tend to get denser as you approach the core.
It's certainly getting better, but we have an uphill battle from the New Yorks, Montreals, Torontos of the world when we missed out on that 1880s - 1930s urban boom prior to widespread car ownership and strict anti-urban land use controls. So much of their stock of walkable, dense neighbourhoods were developed then.
This is helpful in a number of ways, even today:
- lots of precedent of car-free development (and a large existing market for it)
- tons of local examples to point to for tweaks and exceptions to any infills
- cultural and political weight in pedestrian-first planning: so many of your constituents live in walkable neighbourhoods they refuse to accept narrow, shitty sidewalks and unplowed street corners they struggle to get their strollers over.
Another thing I've never understood is why the city doesn't build one big midrise parkade in the center of these neighborhoods for residents to park their cars and retrieve them when required This would allow for surrounding multi-family developments to have minimal parking. It would allow condos and rental buildings to be much more affordable. Better to build one big parkade accessible with a monthly pass for locals rather than have each developer take on the expense of building their own parkade. If these neighborhoods become amenity-rich and are walkable, Id assume the occasional instance someone needs a car they can walk a block down to a community parkade and retrieve it to commute outside the area.
De-bundling parking is what you are describing and is a great idea (read up on Donald Shoup for more on this).
Due to how the City (and most cities) approaches land use regulation, the onus is on the site to "handle" all it's parking needs onsite. This manifests itself into parking requirements which are arbitrary, pseudo-science and not connected to actual supply or demand. The cost of paying for this arbitrary amount of parking is bundled into the price of the building, increasing housing and construction costs for everyone - regardless on if you plan to have a car or not. Once built, parking becomes super painful to "de-bundle" from the building/unit so it's difficult to commoditize and free up (e.g. security gates, owner-only garages, no way to track or mediate disputes etc.) so you might be forced to buy/build a $30,000 parkade stall - but you can't rent it out very easily to recoup that money.
What you are suggesting is far better approach. Make all new developments have zero parking requirements (and perhaps a maximum), instead contributing to a common garage site that can be managed collectively to avoid the challenges that come from the bundling problem - not dissimilar to how Downtown parking worked, you need both sides of the equation (parking maximums/no minimums + public garages). As a bonus, without each building having it's own parking, buildings are cheaper to build, less disruptive (no ramps) and go up faster (less underground). This ultimately translates into simpler, more affordable structures that permanently help more people live in good (and otherwise expensive) locations. All the knock-on effects of environmental and economic benefits from more people living closer together become far more possible too.
Or if you don't want to build a new parking structure, find mechanisms that can unlock all the existing private parking everywhere so it's commodified. Perhaps some clever apps or property management firms can sort this out and find a way to commodify all that private parking that exists. Calgary probably has at least 5 to 10 million parking stalls (all on and off street parking), it's not a physical lack of stalls that the issue - it's the access that needs to be solved.
Improvements are on the way with the removal of commercial parking requirements and the favourable relaxations of parking rules in the inner city. But much more needs to be done to solve this issue and start influencing areas outside the core to transition from car-dependent to "car-lite". Solving parking (by removing it) and car-dependence is the critical factor for all our development issues.
