"Proponents argue that high-speed rail is the only way to save our state from death by sprawl. So what's the holdup?... California's Central Valley is the fastest growing part of the state. It's also where poorly planned developments sprawl like bad fungus into farmland to make way for blocks of cookie-cutter housing developments and the retail boxes to serve them. High-speed rail stations could be the impetus for bringing development back to city centers where it belongs, instead of pushing car-oriented sprawl further out into the fields."
