Numerical Modeling Of Climate Change Impacts On Transportation Embankments, Amr Morsy, Mamata Sapkota, Emma Varela, Odalys Portillo

Mineta Transportation Institute

Embankments are essential components of transportation infrastructure, providing crucial support for long stretches of highways, railways, and other routes in California and around the world. Clay embankments are susceptible to weather-related deterioration processes that can gradually compromise their stability and, in some cases, lead to unexpected failures. Climate change, along with the associated shifts in weather patterns, is projected to adversely impact the weather-related deterioration processes, leading to exacerbated failures and/or shorter service life. Additionally, climate change is projected to increase the frequency of extreme precipitation events, leading to an increase in embankment failure potential. This study evaluated (1) the …

Is Parking Cash-Out Worth It? Comparing Cost-Effectiveness And Climate And Equity Benefits In The Bay Area And South Coast Air Quality Management Districts, Fynnwin Prager, Tianjun Lu, Ashley Membere, Parveen Chhetri

Mineta Transportation Institute

This research explores the potential impacts of California parking cash-out policy changes on the Bay Area and LA County. Parking cash-out—a California law since 1992—requires that certain qualifying employers who subsidize employee parking offer employees the option to give up their parking space and receive cash instead. Studies show parking cash-out substantially reduces VMT and emissions, yet enforcement remains voluntary. Current policy covers few firms (<1%) and employees (around 11%) in the study regions. Policy reform to include companies with 20+ employees could increase this to 18%. Our experimental-design survey (n=963) explores behavioral changes in response to multiple policy variables and finds that 76.9% of employees would accept cash-out if offered, and that participants who had to pay the market rate for parking and were full-time commuters were more likely to switch to using public transportation at lower cash minimums. VMT related to employees covered by parking cash-out are substantial (5.6 million in the Bay Area; 5.7 million in LA County), and account for a combined 6,593 daily tons of GHG. As even limited adoption could have significant environmental benefits, parking cash-out would be a more cost-effective approach to reducing VMT than traditional TDM programs such as trip-reduction programs, workplace parking taxation, or transit subsidies and road diets, though further evidence on the direct influence of parking cash-out on commuter behavior is needed.

Are Santa Clara County Cities Prepared For A Zero-Emission Light Duty Vehicle Future? A Program Evaluation, Benjamin Edelberg

Master's Projects

This research built on the work of Chi-Pei Fang who explored this issue in “Ability of the Bay Area Cities to Accommodate Plug-in Electric Vehicles: A Process Evaluation” (Fang, 2021). Fang recommended that follow-on projects focus on an individual city. This paper moved in that direction, but instead of focusing on a specific city in the California Bay Area, it focused on Santa Clara County (SCC) and the cities within. Additionally, this paper broadened the focus to include all zero-emissions vehicles (ZEVs), a category which not only includes electric vehicles (EVs) but also hydrogen fuel cell electric vehicles (FCEVs).

An Evaluation Of California’S Continuously Appropriated Programs Funded Through Cap-And-Trade, Domingo Candelas

Master's Projects

In 2006, the State of California passed AB 32, the Global Warming Solutions Act. Through this legislation, the state sought to reduce its carbon emissions to 1990 levels by 2020. The California Air Resources Board (CARB) was tasked with doing so and thus instituted the Cap-and-Trade program, a market-based mechanism to reduce emissions. Additionally, legislation has further directed funding on an annual basis for various continuously appropriated programs. This paper will examine the efficacy of those continuously appropriated programs and their legislative intent.

Food Scrapping Programs And Smart Practices For Sb 1383 Compliance In Ten Selected Bay Area Cities, Alia Rizvi Haque

Master's Projects

The Problem

Thirty five percent of landfill waste in California is made up of organic waste, and 18% of landfill waste is made up of food scraps (City of Santa Clara [CSC], 2019). The buildup and decomposition of food scraps at landfills produce methane (CSC, 2019), a pollutant that heats up the atmosphere thousands of times more than carbon dioxide (California Air Resources Board [CARB], 2018). Senate Bill (SB) 1383 is meant to mitigate pollution by requiring the state to reduce organic waste in its landfills to reduce methane production (CARB, 2018). The bill requires the state to reduce organic …

San Jose’S Removing And Preventing Illegal Dumping Program (Rapid): An Evaluation Of Illegal Dumping In San Jose, Rina Laxamana

Urban Goods Movement And Local Climate Action Plans: Assessing Strategies To Reduce Greenhouse Gas Emissions From Urban Freight Transportation, Andrew R. Goetz, Serena Alexander

Mineta Transportation Institute

This report examines how freight transport/goods movement has been addressed in U.S. city climate action planning. Transportation generally is a major contributor of greenhouse gas (GHG) emissions, and freight transport represents a growing component of transportation’s share. Almost all climate action plans (CAPs) address transportation generally, but we wished to focus on efforts to reduce GHG emissions from freight transport specifically. We analyzed 27 advanced local CAPs to determine the degree to which freight transport was targeted in goals and strategies to reduce GHG emissions. We found only six CAPs that included direct measures or programs to reduce freight emissions. …

Measuring Incremental Sb743 Progress: Accounting For Project Contributions Towards Reducing Vmt Under California's Senate Bill 743, Christopher E. Ferrell

Mineta Transportation Institute

On September 27, 2013, California’s governor signed Senate Bill (SB) 743 into law, in part mandating the transition from a level-of-service-based (LOS) measure of transportation environmental impacts to a vehicle-miles-traveled-based (VMT) one in compliance with the California Environmental Quality Act (CEQA). Several California jurisdictions, including San Jose, Pasadena, and San Francisco, have moved quickly to comply with SB 743, so it is no surprise that several of these early-adopter cities have been working hard to develop powerful VMT estimation methods and tools using the most recent research available.

This perspective uses the experiences of an early-adopter city, San Jose, to …

Environmental Studies 129: Water Policy In The Western U.S., Costanza Rampini

Faculty Publications, Environmental Studies

Water, or lack of it, is the defining characteristic of development in the Western United States. Using multiple analytical frameworks, including history, law, economics, environmental science, and sociology, we will investigate the interrelationships of key policies, players, and projects involved in Western water. More specifically, we will critically examine how important federal, state, and local water policies arose and how they affect different stakeholder groups (e.g., irrigators, environmentalists, indigenous peoples, the local citizenry, government entities, public water resource agencies). We will also learn about how stakeholder values and corresponding water policies have changed, or failed to change, over time. Case …

Global Climate Change I-Ii, Kendall Barrett Sooter, Dione Rossiter, Costanza Rampini

Faculty Publications, Environmental Studies

Many different scientific observations and measurements indicate that Earth is experiencing global-scale changes in climate, i.e., in the long-term distributions of temperature, cloud cover, precipitation, and extreme weather events. Scientific consensus considers most these changes to be caused or accelerated by human activities. The economic, ecological, social, and cultural challenges caused by global climate change will affect everyone on the planet, and are very likely to have disproportionate impacts on developing nations. In this course, we will study global climate change from an interdisciplinary perspective, incorporating natural and social science approaches to understanding processes and effects.
