Entire neighborhoods are set up in a grid formation with each "block" being a mile on the side with housing and parks in the middle. You'll almost always need to travel a "block" or two to get to anything of interest.
Big problems being
1. Distance
2. Heat (120f+ 50c+) in the summer
3. Very car centric city, everyone is driving fast so the sidewalks are narrow and the cars are loud
