My idea is to create numerous "neighborhoods" with the addition or re-purposing of buildings into shops, cafes, and galleries. Create xeriscaped parks that encourage activities such as reading, walking, and play. Add solar gathering shade structures to power reclaimed water misters and safety lights. Make the interiors of these neighborhood limited to pedestrian only traffic with easy access to public transportation services. Create great traffic flow around these areas by creating more bus pull off areas, covered train stations, and secure parking. Compliment everything with raised islands, planters, benches, sculpture, and other public art to encourage festivals, art fairs, and a general sense of community.
