Project Summary
Local and regional planning entities are directing substantial employment and housing growth into transit corridors to achieve the sustainability goals of California Senate Bill 375. Despite the substantial focus on transit investment and infill growth, our knowledge base for understanding near-transit infill land use dynamics remains limited. This research will shed light on whether existing plans will be sufficient to encourage favorable land use changes which reorient growth into transit corridors by examining two critical dynamic processes: (1) transit system improvements/expansions and (2) associated land use changes, particularly infill and redevelopment dynamics. More specifically, the project will (a) develop a historical geo-database of the dynamic changes in transit systems and land use over the last two decades (i.e., 1990s and 2000s) in southern California, (b) identify key transit system and policy factors that can shape and re-shape land use patterns in surrounding areas, and (c) analyze infill and redevelopment dynamics associated with transit system improvements/expansions using a parcel- based land use change model. Results will provide insights into the expected nature and magnitude of impacts of urban rail transit system improvements/expansions on infill and growth, and will support on-going efforts to more effectively integrate transportation and land use planning.
