The broken down state of the city's neighborhoods offers a unique opportunity to redesign them. Things like creating a walking path between two small colleges and creating biking paths from old rail lines. Cox wants to enable each neighborhood to have basic services within a twenty minute walk.

I can say that as it is, the process of development is more like consumer marketing: schedule lots of meetings and interviews that sell people on the idea of accepting development rather than giving them a stake in its success. It encourages confrontational deadlock, a buildup of pressure followed by earthquakes of change, as the developers and government gradually start colluding to strongarm residents when they refuse to budge.
But of course, you can see how the incentives run. If somebody likes their neighbourhood the way it is, and doesn't want change, then if they don't complain about new developments to councillors and planners, they gain nothing. But if they do complain, then there's a chance they can get developments stopped. (Thanks, "community-based planning".) So the cost of complaining is quite small, but the rewards can be quite large.
