There are a number of positions (e.g., traffic engineer) that consider and assess how cars move around, but none I know of dedicated to considering and assessing how people experience the city...whether being in the city is a pleasant or unpleasant. Create a new position (something like livability planner) to advance ideas that will make the city a more pleasant place to be.

A significant portion of the livability planner(s)' time would be devoted to actually going out and experiencing the city. Every corner of it. Even the 'bad' parts. Even in 112 degree weather. I'm not just talking a quick driveby in the car. Actually get out of the car and spend an hour walking around and asking qualitative questions like: How easy is it to get around? Is it a pleasant experience? Would I want to live here? How can we improve the residents' experience of living here?
