In 2008 California passed Senate Bill 375 requiring metropolitan planning organizations (MPO) to develop Sustainable Communities Strategies (SCS) as part of their regional transportation planning process. While the implementation of these strategies has the potential for environmental and economic benefits, rising housing costs and changing neighborhood conditions may compel low-income residents and households to move out of transit-oriented neighborhoods. This out-migration is called “displacement.”

The study examined the relationship between fixed-rail transit neighborhoods and displacement in Los Angeles and the San Francisco Bay Area. The researchers modeled patterns of neighborhood change in relation to transit-oriented development (TOD), and found that TOD is associated with changes in the stability of the surrounding neighborhood, such as increases in housing costs and the loss of low-income households. The research found mixed evidence as to whether gentrification and displacement in rail station areas would cause an increase in auto usage and vehicle miles traveled (VMT). The results support the consideration of displacement in the development of SCSs, and the research also explored the possibility of considering displacement in travel demand models used by the LA and San Francisco MPOs and via off-model tools. Finally, researchers examined the effectiveness of anti-displacement strategies, and the results may be useful for MPOs, local jurisdictions, and communities.
