Paul Romer, an economist at Stanford University, proposes the creation of charter cities as an economic development tool. He believes that a new city requires at least 1,000 square kilometeres of available space. See his TED talk at http://www.ted.com/talks/paul_romer_the_world_s_first_charter_city.html
Roosevelt Roads has about 20.6 square kilometers. However, Puerto Rico City has a tighter focus on being strictly a business enterprise zone, and not a residential area.
