Key Takeaways from SPARCC and Urban Displacement Project’s Gentrification and Displacement Analysis


Today we are launching, an interactive mapping website that allows users to dive into the intersection of vulnerability and displacement pressures across the state of California. This map was designed to inform zoning reform proposals; below we discuss why we took this on, the process, and what this map tells us.

SB50 and Sensitive Communities 

California has long led the world in innovation, from Silicon Valley to Hollywood. For the last decade, it has also conducted a series of grand, and largely successful, policy experiments ranging from regulating greenhouse gas emissions to providing sanctuary for undocumented immigrants.


SB 50 is the fruit of nearly a year and a half of negotiations around Senator Scott Wiener’s legislative proposal to upzone, or increase allowable density, near transit. Responding to critiques of the first iteration of this legislative proposal, SB 827 (which we also examined in a policy brief), SB 50 makes several modifications. Changes between SB 827 and SB 50 include:

Santa Clara County, home to the immense wealth of Silicon Valley and California’s third largest city San Jose, is no exception to the problems of housing insecurity facing the greater Bay Area.
