Neighbourhood consultation is a reaction to past urban planning regrets and failures, where heavy handed government “urban renewal” initiatives razed entire neighbourhoods, most often marginalized and ethnic minority ones.
In the worst case community consultation can be distorted into blind NIMBYism that serves only to slow down all development, but nonetheless we know that from our previous mistakes that consultation is required.
I would count myself among those a bit concerned about Silicon Valley being so eager to “fix” problems with cities. Will Sidewalk Labs employ and listen to urban planning experts that have studied cities for their entire careers or is Toronto going to be a sandbox for clueless software engineers' pet theories?
Will Google be so eager to test out self driving cars that they’ll discount and ignore decades of knowledge about how cars impact neighbourhoods?
