The Southern California Association of Governments (SCAG) region is home to approximately 34,000 warehouses with 1.17 billion square feet of warehouse building space, and undeveloped land that could accommodate an additional 338 million square feet of new warehouse building space. The Industrial Warehousing Study is an update from previous work, which evaluates how the region could accommodate future demand for warehouse space based on key supply chain trends. Study findings were used to formulate discussion points, which will engage policy-makers, logistics industry stakeholders, and public-sector agencies about how best to shape the region’s strategic vision and grow, while balancing economic and environmental objectives.

​In the last ten years transit use in Southern California has fallen significantly. This report investigates that falling transit use. We define Southern California as the six counties that participate in the Southern California Association of Governments (SCAG) – Los Angeles, Orange, Riverside, San Bernardino, Ventura and Imperial. We examine patterns of transit service and patronage over time and across the region, and consider an array of explanations for falling transit use: declining transit service levels, eroding transit service quality, rising fares, falling fuel prices, the growth of Lyft and Uber, the migration of frequent transit users to outlying neighborhoods with less transit service, and rising vehicle ownership. While all of these factors probably play some role, we conclude that the most significant factor is increased motor vehicle access, particularly among low-income households that have traditionally supplied the region with its most frequent and reliable transit users.


The FY2011-2012 Transit System Performance Report provides an assessment of the region’s large and complex public transportation system, including current performance and trends over the past two decades. The annual report was developed in response to anticipated federal rulemaking to address performance-based planning requirements in the Moving Ahead for Progress in the 21st Century (MAP-21), and also to establish performance baselines for the 2016-2040 Regional Transportation Plan/Sustainable Communities Strategy. Key findings from this report include the continued significance of fixed route bus service in the region, the growing importance of demand response transit to support regional mobility and slow growth in per capita transit trips over the last two decades.

On The Move represents a long-range comprehensive plan for the goods movement system in Southern California. The plan is designed to ensure that the region continues to play a vital role in the global supply chain while meeting regional economic goals, addressing critical mobility challenges, preserving the environment and contributing to community livability and quality of life goals. The plan is the final product of the SCAG's Comprehensive Regional Goods Movement Plan and Implementation Strategy, a multi-year effort to collect data, conduct analyses and engage with regional, statewide and national stakeholders covering various aspects of the region’s goods movement system.
