Mapping All the Transit Corridors Targeted for Upzoning Under California's SB 827

Sasha Aickin, former CTO of Redfin, spent the weekend mapping out the footprint of SB 827, proposed by California State Senator Scott Wiener last week. The informal mapping exercise, not official or sanctioned by Senator Wiener, provides a visualization of the broad reach of the proposed bill. In a written post that accompanies the new map, Aickin says "[n]early all of San Francisco would be set for upzoning to 85/55 foot heights, as would significant portions of Los Angeles, Long Beach, San Diego, Oakland, Berkeley, and Sacramento. More surpising [sic] to me, though, is the impact on smaller cities like Bakersfield, Santa Cruz, and San Bernardino, which also have a large amount of 85/55 foot upzoning." 

Wiener agrees with the assessment of many on social media over the past week that the new bill represents an aggressive approach to the state's housing affordability crisis.

The bill is part of a package of bills designed as a "housing-first" policy for the state of California that would follow up on previous bills approved in 2017. Planetizen covered the new bills when Senator Wiener announced the package earlier this month.
