Phoenix, Arizona, founded in 1867 by farmers, is contained within a grid structure on flat terrain. Each main road in Phoenix is spaced out by one mile, adjusting for curvature of the Earth. North-south streets are numbered, east-west streets are named, and ‘Central Avenue’ equally divides the North and South parts of the city. Unlike Calthorpe’s ideas for grid design, Phoenix is a largely auto-dependent city as large parts of Phoenix are not accessible by transit, and is also, despite its sunny weather allowing solar panels, a city that is behind on sustainability, and has a shrinking fresh water supply. As Phoenix expands, sustainability and urban sprawl remain problems, and the grid system despite its logical separation, isn’t adaptable enough to fix its problems.
