Effects of Transit-Oriented Development on Affordable Housing, Job Accessibility, and Affordability of Transportation in the Metro Green Line Corridor of Los Angeles
The premise of this study is that an understanding of catalysts and impacts of social and economic change in the Los Angeles Metro Green Line study corridor and an analysis of current planning policies can help identify how future planning policies may generate more ideal and positive outcomes for the study corridor. This study evaluated the conditions within the transit corridor with four selected station areas defined by a one-mile radius from each station. The stations that make up the transit corridor are along the Los Angeles Metro Green Line that runs east west between Redondo Beach and Norwalk. A mile radius buffer was chosen to fully capture the spacing between the stations linearly and use that to define the corridor’s primary area of influence.
This study evaluated the changes in demographic composition, housing affordability, transportation affordability and job accessibility within the Metro Green Line corridor between the year 2000 and 2010. Trends in the corridor revealed that over a ten-year span, the corridor saw shifts in demographic composition, growth in job and housing densities and increases in the cost of housing.
Over the ten years, the corridor has not yet developed to the standards of a location efficient environment. This study recommends that protection of vulnerable populations such as the high proportion of renter-occupied housing units is important because they are more likely to make up core transit riders that need public transportation. Preserving and building affordable housing near transit would enable households to save money on both transportation and housing expenditures and can work towards making the corridor more affordable. By understanding the three main variables in the context of social equity, a decision-maker can avoid the potential of negative gentrification, displacement, and promote economic viability in the corridor.
