Double the Trouble: A Playbook for COVID-19 and Evacuations

Abstract

Evacuation and response plans require thoughtful strategies that build mandatory evacuation order compliance, reduce vehicular congestion, and increase social equity for disadvantaged populations. However, the novel coronavirus (COVID-19) pandemic coincided with a series of devastating disasters in 2020 that have required mass evacuations, leading to several new compounding effects (i.e., “double the trouble”). Strategies typically used in evacuations (e.g., high-capacity vehicles and public congregate shelters) and movements of people (e.g., evacuees, first responders, and volunteers) could increase the risk of COVID-19 spread and exposure. Moreover, disadvantaged populations who are already disproportionately impacted by disasters and COVID-19 separately could face new challenges in dual crises. To address these new and growing challenges, this playbook employs insights from case studies (n=12), survey data of individuals impacted by public safety power shutoff (PSPS) events (n=210), and expert interviews (n=17). Using these data, the playbook: (i) shares recent lessons learned from case studies of compounding disasters during the pandemic; (ii) offers a primer for the potential compounding impact of PSPS events and disasters; (iii) highlights current considerations in the emergency management and evacuation fields; and (iv) provides a series of actionable checklists to address COVID-19 and a compounding disaster. Relevant stakeholders in disasters and evacuations that should use this playbook include public agencies, first responders, community-based organizations, non-governmental organizations, private mobility companies, public health facilities, and other evacuation stakeholders. The playbook can be adapted for multiple hazards, different local contexts, various agency types, and future pandemics.

Hydrogen Infrastructure Requirements for Zero-Emission Freight Applications in California

Abstract

Zero-emission vehicles are seen as key technologies for reducing freight-related air pollution and greenhouse gas emissions. California’s 2016 Sustainable Freight Action Plan established a target of 100,000 zero-emission freight vehicles utilizing renewable fuels by 2030. Hydrogen fuel cell vehicles are a promising zero-emission technology, especially for applications where batteries might be difficult to implement, such as heavy-duty trucks, rail, shipping, and aviation. However, California’s current hydrogen infrastructure is sparse, with about 25 stations, primarily sited to serve fuel cell passenger vehicles and buses. New infrastructure strategies will be critical for implementing hydrogen freight applications. The researchers analyzed hydrogen infrastructure requirements, focusing on hydrogen fuel cells in freight applications, using a California-specific EXCEL-based scenario model developed under the Sustainable Transportation Energy Pathways program (STEPS) at the Institute of Transportation Studies at UC Davis (Miller et al, 2017). Hydrogen vehicle adoption and demand was estimated for trucks, rail, shipping, and aviation, for a range of scenarios out to 2050.

Answers from the Margins: Participatory Planning with Disadvantaged Communities

Abstract

The public mandate to engage the public in transportation planning processes is in the process of becoming more rigorous and democratic. Transportation agencies are recognizing the limitations of past modes of engagement and seek to connect more dynamically with the public, particularly with historically marginalized communities. Doing this work well is a topic of interest to a growing number of transportation professionals. This study identified four successful engagement processes with historically marginalized communities in California by surveying transportation professionals. Stakeholders at each site were interviewed and public documents from the processes were reviewed to identify common themes for positive public inclusion. Interviewees included community leaders, transportation staff, and consultants. Interviews were coded and analysis was conducted using a mobility justice and critical race studies framework. Ten key themes of successful community engagement with historically marginalized communities were identified. These themes are: (1) trust is crucial; (2) treat community-based organizations as equal partners; (3) pay community partners fairly; (3) let community-based organizations decide what good community engagement is; (5) translate technical jargon; (6) engage in community concerns beyond the scope of the project; (7) address major community concerns such as displacement, policing, and youth development; (8) know local histories of transportation injustice; (9) include the community in the final reporting process; and (10) follow-up on planning with implementation in a timely manner.

California Can Simplify the Housing Element Law to Reduce Administrative Burdens and Improve Social Equity

Abstract

California’s Housing Element law requires all local governments to adequately plan to meet the state’s existing and future housing needs. The law establishes processes for determining regional housing needs and requires regional councils of governments (COGs) with allocating these housing needs to cities and counties in the form of numerical targets. Local governments must update the housing element of their general plans and adopt policies to accommodate the housing targets. The California Department of Housing and Community Development (HCD) reviews all local housing elements and determines whether the elements comply with state law.

Can Plug-in Electric Vehicles in a Smart Grid Improve Resiliency?

Abstract

While the impact of plug-in electric vehicles (PEVs) on electricity generation and transmission has been studied extensively, the impact of PEVs on the resiliency of the local electricity distribution system has not been addressed in detail. Understanding resiliency impacts is important as the increased use of PEVs, and especially the clustering of PEVs in one area (such as a neighborhood), place additional pressures on already aging power grid infrastructure. As an example, charging a large population of PEVs during normal operations can stress system components (such as transformers) resulting in accelerated aging or even failure, which reduces resiliency of the system. On the other hand, PEVs can also increase system resiliency. When connected to the grid, PEVs are an energy resource that can provide electricity for critical services (such as community shelters) during grid outages and facilitate grid restoration by providing electricity to support the restart of transformers and other utility assets.
