Dynamic Flood Risk Assessment For Transportation Infrastructure In Fresno, Ca, Yushin Ahn, Fayzul Pasha

Mineta Transportation Institute

Urban roadway flooding in flat metropolitan environments often shows up as small areas of standing water rather than large, flowing floods. In low-gradient urban environments, subtle micro-topographic features—such as pavement crowns, curbs, and localized depressions—often control where surface water accumulates following rainfall. Accurately identifying these localized ponding areas is important for roadway flood screening and infrastructure management. This study develops a LiDAR-based depression mapping framework to identify roadway segments susceptible to surface ponding in flat urban environments. High-resolution airborne LiDAR datasets were used to generate detailed elevation maps (down to less than a foot in resolution) from ground-classified point clouds …

Mineta Transportation Institute

This research project examines the current state of the practice for disaster public communication, the distrust of government, the training available to public information officers, and the literature available to guide the design of effective public outreach messaging, especially for rapid on-set events. Growing distrust in government had led to lack of public confidence in public agency messaging during emergencies, yet public agency public information officers are using multiple pathways, including both traditional and social media resources, to try to reach impacted communities effectively. The introduction explains the development of wildfire events in the West and their context. A literature …

“Tele-Commuting” During The Covid-19 Pandemic And Beyond: Unveiling State-Wide Patterns And Trends Of Telecommuting In Relation To Transportation, Employment, Land Use, And Emissions In Calif, Tianjun Lu, Jian-Yu Ke, Fynnwin Prager, Jose N. Martinez

Mineta Transportation Institute

Telecommuting, the practice of working remotely at home, increased significantly (25% to 35%) early in the COVID-19 pandemic. This shift represented a major societal change that reshaped the family, work, and social lives of many Californians. These changes also raise important questions about what factors influenced telecommuting before, during, and after COVID-19, and to what extent changes in telecommuting have influenced transportation patterns across commute modes, employment, land use, and environment. The research team conducted state-level telecommuting surveys using a crowd-sourced platform (i.e., Amazon Mechanical Turk) to obtain valid samples across California (n=1,985) and conducted state-level interviews among stakeholders (n=28) …

Vulnerable Populations And Flooding: A Bay Area County Public Alert And Warning Case Study, Victoria Castro

Master's Projects

Public alert and warning systems are crucial tools that save lives and protect property in times of emergencies. In the past several decades, natural disasters have struck the nation, and effective public alerts and warnings were not disseminated to all impacted populations, calling into question the effectiveness of emergency communication systems (Wimberley, 2012).

As an example, in 2012, when Hurricane Sandy hit the east coast, public alert and warning systems reached those who had access to technological devices. However, emergency managers and alerting authorities faced the challenge of alerting all groups, including the homeless and individuals with access and functional …

Would A Regional Fire Emergency Communications Center In Placer County Improve Efficiency For Participating Fire Agencies?, Reginald Williams

Master's Projects

Dispatch centers serve multiple functions within a community, dependent on the resources it controls. Centers operating in PC function as the primary 911 answering point, using “call-takers” and “dispatchers” to triage emergencies and respond the appropriate resources. Call-takers are trained personnel who are hired to answer 911 calls from the community, and input valuable information into a computer-aided dispatch (CAD) system, that geolocates the emergency location and provides historical information of emergencies at a given location. Many call-takers are trained to provide instructions to the caller to ensure that they are 1) out of harm's way and 2) to assist …

A Program Evaluation Of The Town Of Woodside, Plumas County Fire Safe Council, And Mountain Communities’ Fire Safe Council Defensible Space Projects, Mandeep Gill

Master's Projects

California is one of the most fire-prone regions in the world, with every passing year becoming more hazardous. With a tremendous amount of loss and damage occurring every year due to wildfires, property owners must prepare their homes and structures to withstand fires as much as possible. The best way to achieve this is by building and retrofitting homes with fire-resistant materials and creating defensible space around the property (Cal Fire, n.d.). Although it is the best way to protect one’s property, it is often times difficult for property owners to do so because of financial or physical limitations, or …

A Process Evaluation Of Intelligence Gathering Using Social Media For Emergency Management Organizations In California, Alan Barner

Master's Projects

When responding to an emergency, correct and timely information is often the difference between a successful response and a potential disaster. The information that emergency managers in California receive from the public often dictates how agencies respond to emergencies. The emergence of social media has presented several benefits to emergency managers regarding intelligence gathering during the emergency response process. Simultaneously, the emergence of social media has raised several concerns for the stakeholders involved. One major issue involves inaccurate information circulating on social media platforms during ongoing disasters. If emergency managers cannot discern incorrect information from correct information, disaster response may …

Multifidelity Prediction In Wildfire Spread Simulation: Modeling, Uncertainty Quantification And Sensitivity Analysis, Mario Miguel Valero, Lluís Jofre, Ricardo Torres

Faculty Research, Scholarly, and Creative Activity

Wildfire behavior predictions typically suffer from significant uncertainty. However, wildfire modeling uncertainties remain largely unquantified in the literature, mainly due to computing constraints. New multifidelity techniques provide a promising opportunity to overcome these limitations. Therefore, this paper explores the applicability of multifidelity approaches to wildland fire spread prediction problems. Using a canonical simulation scenario, we assessed the performance of control variates Monte-Carlo (MC) and multilevel MC strategies, achieving speedups of up to 100x in comparison to a standard MC method. This improvement was leveraged to quantify aleatoric uncertainties and analyze the sensitivity of the fire rate of spread (RoS) to …

Preparing For Wildfire Evacuation And Alternatives: Exploring Influences On Residents’ Intended Evacuation Behaviors And Mitigations, Amanda M. Stasiewicz, Travis B. Paveglio

Faculty Research, Scholarly, and Creative Activity

Understanding residents' intended evacuation behaviors is an increasingly important component of managing complex wildfire events in the United States and elsewhere. Growing evidence suggests that local populations consider a range of potential evacuation behaviors during fire events, yet fewer efforts explore rural residents' evacuation intentions or their relationship to wildfire mitigations that reduce risk or aid in fire suppression. This study explores evacuation intentions among wildland-urban interface residents in Pend Oreille County, Washington, USA. We explore how mitigation performance (e.g., fuel reduction efforts, structure improvements, active firefighting preparation) differs across three emergent categories of evacuation intentions and evaluate whether a …

Harmonizing Climate Change Mitigation And Adaptation In Transportation And Land-Use Planning In California Cities, Serena E. Alexander, Asha Weinstein Agrawal, Ashley M. Hooper, Michael R. Boswell

Mineta Transportation Institute

Abstract: Recent extreme weather events in California—wildfires, drought, and flooding—make abundantly clear the need to plan effective responses to both the causes and the consequences of climate change. A central challenge for climate planning efforts has been identifying transportation and land-use (TLU) strategies that simultaneously reduce greenhouse gas emissions (“mitigation”) and adapt communities so that they will be less affected by the adverse impacts of climate change (“adaptation”). Sets of policies that collectively address both mitigation and adaptation are known as “integrated actions.” This study explores municipal climate planning in California to determine whether cities incorporate integrated actions into their …

What Factors Influence The Success Of Soft Story Retrofit Programs? The Example Of San Francisco’S Program, Thanh Thuy Nguyen

Master's Projects

In the event of an earthquake, one of the types of structures that is most susceptible to collapse is soft-story buildings (Association of Bay Area Governments [ABAG], 2016). Built before current regulation and codes were enacted, a soft-story residential building is a building that has commercial space or open parking on the first floor, with units built above it (ABAG, 2016). The first floor has a weak structure and the units above the first floor weigh heavily on it (Arroyo, 2019). Due to their building structure, these properties may sway or collapse during an earthquake, ultimately causing fatalities and damage …

Benchmarking The Delivery Of Fema Training To Operation Line Employees Within Surface Transit Agencies, Matthew E. Mccann

Master's Projects

In February 2003, in the aftermath of the September 11, 2001 terror attacks, the administration of then President George W. Bush developed Homeland Security Presidential Directive-5 (HSPD-5), which mandated the use of the National Incident Management System (NIMS), and the Incident Command System (ICS) by all agencies receiving federal funding (Bush, 2003). The intent of HSPD-5 was to “enhance the ability of the United States to manage domestic incidents by establishing a single, comprehensive national incident management system” (Bush, 2003), or in other words, to ensure that emergency response by the many disparate agencies under the umbrella of government funding …

Grassroots Relief: Informal And Community-Based Response To Extreme Weather Events From Occupy Sandy To The Cajun Navy, Gordon Douglas, Eric Klinenberg, Liz Koslov

Faculty Publications, Urban and Regional Planning

This study examines the role that local grassroots efforts play in disaster response and recovery. Drawing on findings from an ongoing research project on the experience of Hurricane Sandy in New York City since 2012 as well as new data from more recent hurricanes and other events, we show how volunteers, community-based organizations, and activist groups often play an important role in both immediate response and longer-term recovery efforts. Many communities hit hard by Sandy and other disasters were significantly aided by locally organized and 'informal' responses, often from groups that initially had nothing to do with emergency preparedness (community …

Reciprocity And Vernacular Statecraft: Andean Cooperation In Post-Disaster Highland Ecuador, A. J. Faas

Faculty Publications, Anthropology

Cooperative labor parties known throughout the Andes as mingas, although outwardly appearing to be the same cultural institution, are practiced quite differently and with varying meanings in different socioeconomic contexts. This article discusses how minga cooperation came to exhibit contrasting, yet intimately related, patterns of practice and social relationships in both a displaced, disaster-affected village and a disaster-induced resettlement. It describes actors in these groups appealing to ostensibly common repertoires of shared meaning and culture, while organizing themselves in distinct ways in order to access and control scarce resources. In one village, minga participation is largely sustained through traditional …
