Accessory Dwelling Unit (ADU) Potential in the SCAG Region

Promoting accessory dwelling units (ADUs) construction is an increasingly viable option for addressing the region’s housing needs. To support ADU planning, SCAG has collaborated with Cal Poly Pomona’s Department of Urban and Regional Planning to identify parcels with potential for detached ADUs based on physical capacity using criteria from recently amended State law and parcel-level geospatial data from SCAG. The 6th cycle housing element requirements involve estimating ADU development potential, removing barriers to their development, and programs incentivizing ADUs including affordable rental ADUs.

This project comprehensively examines the physical ADU capacity of sites in the six-county SCAG region, focusing only on detached ADUs. ADU eligibility and physical capacity under a range of local policy scenarios have been incorporated into the Housing Element Parcel (HELPR) tool to enable users to screen sites based on this study’s criteria. Part of SCAG’s regional data platform, the HELPR tool allows users to explore and analyze over five million parcels in the SCAG region based on updated, curated versions of parcel-level land use data in light of recent housing element requirements.

Racial Equity: Baseline Conditions Report

Racial Equity: Baseline Conditions Report Cover Image (March 24, 2021 Revision)

In July 2020, SCAG’s Regional Council made a commitment to advancing justice, equity, diversity, and inclusion throughout Southern California. For the region to become healthy, livable, sustainable, and economically resilient, SCAG needs to dramatically improve outcomes for low-income families and people of color. To that end, SCAG’s core function, its planning work, must directly address the long‐standing systemic and institutional barriers that have fostered inequities in health, wealth, and opportunities. SCAG staff are developing an Early Action Plan to help facilitate the consistent integration of equity into its planning work. The purpose of this report is to highlight past transportation and housing policies and practices that yielded the inequitable conditions that exist today and provide a preliminary baseline assessment of racial equity in Southern California to inform future planning. These inequitable conditions fall into categories aligned with the goals of SCAG’s long-range plan, Connect SoCal: economy, healthy/complete communities, mobility, and environment.

Transportation Research Board 100th Annual Meeting

TRB 2021 Annual Meeting Graphic

In January 2021, SCAG presented at the Transportation Research Board’s (TRB) 100th Annual Meeting. This annual conference organizes a program that includes workshops, committee meetings, and exhibits, attracting transportation professionals from around the world. Typically held in Washington, DC, this convening was held as a virtual event amid the COVID-19 pandemic. The overall theme of this year’s meeting was “A Century of Progress: Foundation for the Future.”

SCAG presented the following:

  • Paths to Clean Vehicle Technology and Alternative Fuels Implementation in San Bernardino County, California – Completed in partnership with the San Bernardino County Transportation Authority (SBCTA) in July 2020, this presentation is one of several ongoing efforts to understand and help facilitate the region’s transition to a cleaner goods movement system. This study had 3 major components: development of a Scenario Analysis Tool, Stakeholder Outreach, and development of an Action Plan for local governments in San Bernardino County. This presentation describes the development and application of the scenario analysis tool that quantifies emissions and cost impacts of alternative paths to clean vehicle and fuel implementation. Five scenarios where different fuels and technologies were phased into the fleet at different rates were compared.
  • Disadvantaged Communities Active Transportation Initiative (DCPI) – The DCPI seeks to make active transportation plans and their implementation more assessable to all jurisdictions within the region. This presentation details the development and implementation of the Active Transportation Toolkit pilot, which provides the materials needed to help under-resourced communities envision and implement their own plans for walking and biking with the support of city staff. For this effort, SCAG partnered with community-based organizations in seven disadvantaged communities to engage in community outreach, facilitate capacity-building trainings, and implement demonstration events. This pilot effort will lead to the adoption of seven Active Transportation Plans, and the Toolkit will be released for public use in spring 2021.
  • SCAG Go Human 2020: Case Studies in Equity-Centered Strategies using the SCAG Go Human Kit of Parts – The Go Human Kit of Parts program brings a wide range of active transportation interventions to under-resourced communities in the short term, allowing residents to enjoy them and understand their benefits without having to wait many years for full implementation. This presentation reviews the equity considerations of the program and explores how a regional government active transportation program, in the wake of COVID‐19 and global demonstrations for racial justice, can prioritize equity, community‐led strategies and Black, Indigenous and People of Color communities within planning and engagement.
  • SCAG Go Human Campaign – SCAG developed and implemented a hyper-targeted, regional marketing and outreach campaign to raise awareness about safety measures to reduce traffic-related deaths and injuries among people who walk and bike in six Southern California counties comprised of 19 million people. SCAG developed the campaign strategy from analysis of the High Injury Network and SB 535 Disadvantaged Communities, as well as from input from the Go Human Steering Committee. In addition to paid physical and digital media, SCAG extended the reach of the campaign through the use of co-branded safety material distributed to local jurisdictions. After the most recent campaign in 2020, the SCAG Go Human Campaign exceeded 1 billion impressions and printed over 25,000 material for local partners. Please visit the SCAG Go Human webpage for more information on the campaign.
  • Environmental Justice & Equity: Spatiotemporal Analysis of Jobs Housing Fit in Southern California – Jobs-housing balance has become a major issue in urban and transportation planning and public policy. Among planners and policy makers, the imbalance of jobs and housing is considered as one of the key contributors to traffic congestion and air pollution, and an impediment to environmental justice. On the other hand, a proper balance of housing and jobs can help people to live close to their workplace, thus reducing overall congestion, vehicle miles traveled (VMT), and greenhouse gas (GHG) emissions. As part of the jobs-housing imbalance/mismatch analysis for Connect SoCal, SCAG conducted the analyses of jobs-housing ratio and low-wage jobs-housing fit for Southern California at two scales—jurisdiction and the census tract (roughly equivalent to a neighborhood), based on the JHFIT methodology developed by UC Davis Center for Regional Change.

Regional Briefing Book

Regional Briefing Book

SCAG’s Economic Summit began in the wake of the Great Recession as a convening to expand the region’s economic base and to determine priorities for the region that help businesses, public agencies, and communities improve economic vitality.

However, 2020 has brought increased recognition that improving economic health and achieving equity will require broader approaches that address social, economic, and environmental factors that influence the economy in the wake of recent events, including those related to the COVID-19 pandemic. Relatedly, there are a growing number of emerging initiatives which provide the building blocks to address systemic institutionalized racial inequities. Many challenges remain to address racial disparity within an inclusive economic development strategy.

This briefing book represents a first step toward a more comprehensive framework for an inclusive economic recovery.

It is comprised of five parts: 1.) State of the SCAG Region Economy & Outlook; 2.) Modeling the Economic Impacts of COVID-19 Through FY 2021; 3.) Centering Racial Equity as a Driver for Economic Recovery; 4.) Conclusions & Next Steps; 5.) Appendix: County Insights

Potential Economic Impacts of COVID-19 in the SCAG Region

Potential Economic Impacts of COVID-19 in the SCAG Region Cover Image

​This white paper provides an initial assessment of potential employment and taxable sales implications of the COVID-19 pandemic in the region as of the end of April, 2020. A discussion of data and information used in their development is also provided. The analysis assumes a low-point occurring around June 1, 2020 with a resumption of some economic activity thereafter, but a long, slow recovery extending through the end of 2021. Additionally, numerous assumptions are made about the decline and potential recovery trajectory in individual industry sectors. Future taxable sales in the SCAG region are compared to a baseline and assume a linear growth trajectory between June 2020 and December 2021. Employment and economic output are modeled separately using a structural economic forecasting model (REMI). Analyses of the pandemic’s impact at this stage are subject to an extremely high level of uncertainty; importantly this analysis does not assume a second wave of the pandemic or specifically model the impact of additional federal action. As the pandemic unfolds and additional data become available, these assumptions, modeling strategies, and outputs can be revised.

Falling Transit Ridership: California and Southern California

Falling Transit Ridership Cover Image

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.
