Marking the largest change in California land use laws in a generation, the California legislature has approved SB 375, a bill which promotes both affordable housing and less sprawl in the state.  In a coalition as landmark as the legislation itself, affordable housing advocates, the building industry, environmentalists, and local governments came together to endorse legislation that will encourage more compact development along transit corridors.  The legislation's key feature is to integrate what are now three separate planning processes -- regional development, affordable housing and transit development -- into a synchronized system.  This is considered a critical step in achieving California's goal of reducing greenhouse gas emissions, as established in 2006 through AB 32.
