I haven't been on this site long enough--or enough recently--to know whether you've already found this fabulous tool for picturing what smart growth really looks like. Regrettably, they haven't tagged JAX in this site, but what they have done is a blueprint for smart change:
http://www.nrdc.org/smartGrowth/visions/Per the website, "With generous assistance from our friends at Urban Advantage, NRDC has created a map of the United States featuring 70 locations across the country that are ripe for transformative change. Open the map, zoom in on a location and, without leaving our web site, you will be shown a Google Maps satellite view of the existing site, given some context about the metro area, and be treated to a brief slide show demonstrating how each can be converted, step-by-step, from sprawl, vacant property or disinvestment into a lively, beautiful neighborhood . . .â€
Totally sounds up the MetroJAX alley . . .
