I'm a city planner and a big fan of drones. I make them, fly them, and crash them regularly. It seems that most city laws concerning drones have been blanket laws to ban their use in certain spaces altogether. That seems short sighted.
Here I made a small proposal on how we could make zoning laws to maximize the good parts about drones and cut down on prospective nuisances. http://www.thehumanitarianspace.com/2014/08/zoning-and-urban-land-use-planning-for.html - I would LOVE to have feedback from within the drone community.
