The arguments for parking minimums always sound so poorly thought through that they would be laughed out of the park if it weren't for the entrenched tradition.
Parking minimums are based on basically no real data. They were also a significant factor in the destruction of many downtown areas as many buildings were bought, demolished, and turned into surface level parking lots, which is a poor use of valuable land in a downtown core.
Parking minimums also promote overbuilding parking for strip malls, box stores and even residential developments, artificially increasing the amount of land these developments need.
Reporting back by 2028 or sooner sounds like polliticsl speak for " lets not really care about this during our terms/put this off til people forget we said we'd look into it". 5 years is a ridiculous amount of time to study this subject and far too long to wait to start fixing our urban fabric.
If parking miniums aren't to be eliminated, they should be significantly reformed to at least try to use some real data and give businesses more flexibility in determining their parking requirements.
This is why my position on the greenbelt is "open it up to any construction but you have to pay to service that construction with frequent rail-based rapid transit instead of cars". Which means green ultra-high-density. Cut and cover some subways out of Aldershot GO and build an new Barcelona around them. Use every part of the Buffalo.
