There's a proposal that was floated some years back in Atlanta around grocery stores. South of interstate 20 is a food desert. So the proposal said that a corporation and it's subsidiaries could not build a new grocery store anywhere in the city, without also building one in a disadvantaged area. It never went anywhere but I wonder if this might work in an area where more housing is needed. In order to get the building permit you are required to offset one project with a low income project in pre-determined areas.
