Not my experience at all in my neighborhood. Development gets torpedo'ed by current residents. Parking and traffic almost always being the primary one. As in, more parking minimums. Developers showing up are the only people trying to actually build anything at all, most community members are NIMBY.

Not sure what a private developer would have to do with public transit though. That's the city's job to provide and figure out the routes for. Developers bring projects accordingly, and the local residents veto 12 story apartment buildings built on current strip-malls 2 blocks away from train stations. Residents using transparently bullshit environmental and walking/biking infrastructure "concerns" as just another way to block things.

I'll take building stuff - even if flawed - over the current state of never building anything ever any day of the week.
