Oakland's Freeway-Free Flatlands Run Cooler but Carry Seismic Risk

Earth9 planners have published a case study showing Oakland's flatlands average 1.2 to 1.8 degrees Celsius cooler in summer than their Earth-0 counterparts, credited to the green corridors that replaced elevated freeway footprints after 1989. The same report flags elevated liquefaction risk on some transit-prioritized parcels where soil stabilization was deprioritized during reconstruction.
