Truck Parking and Idling is Having an Impact on Disadvantaged Communities in California

Abstract

Under California Assembly Bill 617 (Garcia, 2017), local and state agencies are working to reduce air pollution exposure in low income communities. These communities—often referred to as AB 617 communities—are disproportionately impacted by air pollution due to their proximity to transportation corridors, industrial installations, and logistics centers. A research team at the University of California, Davis investigated the impact of truck parking related activities on air quality in California’s AB 617 communities in Kern County, including truck idling, time spent searching for parking, and parking locations in communities. Searching for parking involves trucks driving extra miles to find available parking spaces, which leads to additional fuel consumption and increased emissions of pollutants such as nitrogen oxides (NOx) and particulate matter (PM 2.5 and PM 10). Once parked, prolonged or illegal parking can exacerbate congestion, noise, and localized pollution. These combined activities heighten exposure to harmful emissions in EJ communities, potentially leading to health issues (e.g., asthma and cardiovascular diseases). A comprehensive policy framework addressing truck parking facilities, management, and air pollution control is crucial for improving air quality and living conditions in AB 617 communities. There are a number of initiatives that could contribute to improving the conditions on these communities.

Assessing and Addressing the Mobility Needs of an Aging Population

Project Summary

By 2030 the older adult population in California is expected to nearly double to over 8.6 million people. Many if not most older adults will reduce and eventually stop driving for medical and non-medical reasons, which in turn can impact mental health and activities including accessing needed medical care. In order to plan for these mobility changes and to support healthy aging in California, this proposed project will build upon work that the research team has conducted in California (funded by National Institute of Health and National Highway Traffic Safety Administration) and nationally with members from the Center for Disease Control and Prevention’s Healthy Aging Network (funded by the Federal Transit Administration) to understand the mobility needs of older adults in California. A comprehensive literature review is proposed followed by a representative survey of the aging adult population to assess: (i) mobility needs, (ii) impact of emerging technology on mobility, and (iii) impact of neighborhood characteristics on mobility. Through contracting with established survey companies, the team has conducted successful surveys of representative samples of the California population.

Regional Industrial Land Preservation: Perspectives from San Francisco Bay Area Cities on a Priority Production Area Program

Project Summary

Many regions in California have prepared long-term plans for goods movement, recognizing the need to develop freight facilities to accommodate the transformation and growth of logistics in the state. Yet, for most, planning for industrial lands – and related jobs –is an afterthought. The Metropolitan Planning Commission and the Association of Bay Area Governments (ABAG) have thus decided to enact a new program that allows jurisdictions to prioritize industrial uses (the Priority Production Areas or PPAs). PPAs will then be included in the region’s Sustainable Communities Strategies. Although ABAG’s Executive Board adopted the program in early 2017, and it is mentioned in the 2040 Plan Bay Area, the program has not yet been developed. This translational project will help the Bay Area’s regional agencies develop the program. Building on program guidelines suggested by the recent “Goods Movement and Industrial Land Supply” study (funded by Caltrans), this project will interview and convene UC, regional agency, local jurisdiction staff, and economic development organizations to discuss and develop potential guidelines for designating PPAs. UC-Berkeley will also assist by identifying possible incentives and other implementation mechanisms and providing data and analysis to assist jurisdictions interested in participating in the program.

Encouraging Mode Shift from Truck to Rail for California Produce

Project Summary

The movement of California goods is one of the largest employment generators within the state and is critical to both the structural health of the economy and the physical health of its citizens. However, the goods movement sector is subject to market failures that may result in suboptimal modal shares, in particular an excess of truck traffic some of which would ideally be diverted to rail. While opportunities for modal shift are limited within the state, there are significant possibilities for California exports. Examining the agricultural sector, California is one of the largest producers of perishable produce in the world and a majority of this produce leaves the state on a truck, despite the fact that rail dominated the market through the mid-1970’s. Significant inertia exists today among the grower-shipper- buyer network that has frozen in place the domination of the trucking industry among perishable produce, even though rail movement would reduce social cost in many cases. While the private sector is unlikely to invest in a modal shift given the historically low fuel prices, it is possible that there is an opening for a public-private partnership (PPP) that could provide a gentle push for change. This project will build on the initial work from the “Rail and the California Economy” project and explore the possibility of using public initiatives—including capital investment, risk sharing, subsidy, and other interventions—to support new rail infrastructure for the perishable produce industry. Specifically, the report will review the current state of affairs in two major growing regions, the Salinas Valley and the southern Central Valley, and analyze how goods move and the benefits of a modal shift to rail. The report will then identify public-private partnerships that might promote a shift to realize these benefits. Additionally, if time permits the project may review an existing PPP involving rail, the reconstruction of the Colton Crossing in southern California and the public benefits associated with its completion.
