This project’s goal is to lift up promising approaches, suggest new strategies and encourage honest conversations that result in public policy solutions to income and racial segregation and poverty. The overarching question that motivates this work is:

  • What are effective policies and strategies that promote access to high-opportunity amenities for low-income families?

As a first step, the researchers surveyed efforts on the ground in the metropolitan areas encompassing Seattle, Washington; Portland, Oregon; and San Diego, California, to determine whether there were any candidates for deeper study. We selected these three metropolitan areas for several reasons. First, prior interaction revealed ...


Integrating Satellite And Ground Measurements For Predicting Locations Of Extreme Urban Heat, Vivek Shandas, Jackson Lee Voelkel, Joseph Williams, Jeremy Hoffman Jan 2019

Integrating Satellite And Ground Measurements For Predicting Locations Of Extreme Urban Heat, Vivek Shandas, Jackson Lee Voelkel, Joseph Williams, Jeremy Hoffman

Urban Studies and Planning Faculty Publications and Presentations

The emergence of urban heat as a climate-induced health stressor is receiving increasing attention among researchers, practitioners, and climate educators. However, the measurement of urban heat poses several challenges with current methods leveraging either ground based, in situ observations, or satellite-derived surface temperatures estimated from land use emissivity. While both techniques contain inherent advantages and biases to predicting temperatures, their integration may offer an opportunity to improve the spatial resolution and global application of urban heat measurements. Using a combination of ground-based measurements, machine learning techniques, and spatial analysis, we addressed three research questions: (1) How much do ambient temperatures ...


Nature-Based Designs To Mitigate Urban Heat: The Efficacy Of Green Infrastructure Treatments In Portland, Oregon, Yasuyo Makido, Dana E. Hellman, Vivek Shandas Jan 2019

Nature-Based Designs To Mitigate Urban Heat: The Efficacy Of Green Infrastructure Treatments In Portland, Oregon, Yasuyo Makido, Dana E. Hellman, Vivek Shandas

Urban Studies and Planning Faculty Publications and Presentations

Urban heat is a growing environmental concern in cities around the world. The urban heat island effect, combined with warming effects of climate change, is likely to cause an increase in the frequency and intensity of extreme heat events. Alterations to the physical, built environment are a viable option for mitigating urban heat, yet few studies provide systematic guidance to practitioners for adapting diverse land uses. In this study, we examine the use of green infrastructure treatments to evaluate changes in ambient temperatures across diverse land uses in the city of Portland, Oregon. We apply ENVI-met® microclimate modeling at the ...

Urban Studies and Planning Faculty Publications and Presentations

Integrated land use and transportation models have evolved along a spectrum from simple sketch planning models to complex microsimulation models. While each has its niche, they are largely unable to balance the flexibility and realism of microsimulation and the speed and interactivity of simple models. The Regional Strategic Planning Model (RSPM) aims to fill this gap by taking a microsimulation approach while making other simplifications in order to model first-order effects quickly. It enables planners to consider the robustness of prospective policies in the face of future uncertainties by accepting a broad range of inputs and allowing rapid simulations of ...


Small Steps On The Long Journey To Equality: A Timeline Of Post-Legislation Civil Rights Struggles In Portland, Leanne Claire Serbulo Oct 2018

Small Steps On The Long Journey To Equality: A Timeline Of Post-Legislation Civil Rights Struggles In Portland, Leanne Claire Serbulo

Urban Studies and Planning Faculty Publications and Presentations

Leanne Serbulo presented a timeline of civil rights struggles in Portland, Oregon, at a public history roundtable at the Oregon Historical Society commemorating the fiftieth anniversary of the 1968 Fair Housing Act. In this record of her presentation, Serbulo documents milestones in dismantling racial discrimination between 1949 and 1990. For this timeline, Serbulo researched Metropolitan Human Relations Commission (MHRC) records held at the Portland City Archives and traces how the commission navigated the process of improving race relations in the city and Multnomah County. As Serbulo argues, “civil rights legislation was simply the first step in a long and unfinished ...


A Fair Distribution Of Accessibility: Interpreting Civil Rights Regulations For Regional Transportation Plans, Karel Martens, Aaron Golub May 2018

A Fair Distribution Of Accessibility: Interpreting Civil Rights Regulations For Regional Transportation Plans, Karel Martens, Aaron Golub

Urban Studies and Planning Faculty Publications and Presentations

The US Department of Transportation requires metropolitan planning organizations (MPOs) to consider social equity in their plans and projects in accordance with civil rights–related laws. In this paper, we suggest four interpretations of directives’ distributional standards in relation to accessibility. Employing this framework, we review the equity assessments of regional plans of the ten largest MPOs in the United States. Against our expectations, we find that MPOs tend to employ relatively strong distributional standards, albeit never explicitly. We argue that more explicit guidance regarding standards would improve the fairness and consistency of planning practice

Abstract:

This article focuses on the complex relationship between development and disaster risk. Development and disaster risk are closely linked as the people and assets exposed to risk, as well as their vulnerability and capacity, are largely determined by development processes. Transformation is key to moving from current development patterns that increase, create or unfairly distribute risks, to forms of development that are equitable, resilient and sustainable. Based on a review of existing literature, we present three opportunities that have the potential to lead to transformation in the development-disaster risk relationship: (i) exposing development-disaster risk trade-offs in development policy and ...

Assessing Vulnerability To Urban Heat: A Study Of Disproportionate Heat Exposure And Access To Refuge By Socio-Demographic Status In Portland, Oregon, Jackson Voelkel, Dana E. Hellman, Ryu Sakuma, Vivek Shandas

Urban Studies and Planning Faculty Publications and Presentations

Extreme urban heat is a powerful environmental stressor which poses a significant threat to human health and well-being. Exacerbated by the urban heat island phenomenon, heat events are expected to become more intense and frequent as climate change progresses, though we have limited understanding of the impact of such events on vulnerable populations at a neighborhood or census block group level. Focusing on the City of Portland, Oregon, this study aimed to determine which socio-demographic populations experience disproportionate exposure to extreme heat, as well as the level of access to refuge in the form of public cooling centers or residential ...


Goodbye To The National Endowment For The Arts?, Naomi Adiv Feb 2018

Goodbye To The National Endowment For The Arts?, Naomi Adiv

Urban Studies and Planning Faculty Publications and Presentations

In the shadow of the truly egregious policies rolled out by the Trump administration in their first year in office (anti-Muslim and anti-immigrant policies, de-staffing the State Department into paralysis, shrinking national monuments, strangling the ACA), and a general tone of chaos surrounding the office of the presidency, a standing threat remains. That is: among other cuts, freezes and gag orders, the administration has vowed to defund the National Endowment for the Arts (NEA), National Endowment for the Humanities (NEH) and the Corporation for Public Broadcasting (CPB). Here, I demonstrate how current political arguments around defunding the NEA are derived ...


Hedonic Modeling Of Commercial Property Values: Distance Decay From The Links And Nodes Of Rail And Highway Infrastructure, Kihwan Seo, Deborah Salon, Michael Kuby, Aaron Golub Feb 2018

Hedonic Modeling Of Commercial Property Values: Distance Decay From The Links And Nodes Of Rail And Highway Infrastructure, Kihwan Seo, Deborah Salon, Michael Kuby, Aaron Golub

Urban Studies and Planning Faculty Publications and Presentations

This study investigates the impacts of positive and negative externalities of highways and light rail on commercial property values in Phoenix, Arizona. We hypothesize that the positive externality (i.e., accessibility) of highway and light rail accrues at exits and stations, whereas nodes and links of highways and light rail emanate negative effects. Positive and negative effects decay with increasing distance and are captured by multiple distance bands. Hypotheses are tested using a spatial error regression model. Results show that commercial property values are positively and significantly associated with the accessibility benefits of transport nodes. The distance-band coefficients form a ...

In response to austerity politics and market-based governance of urban land, large-scale social protest has erupted in the public spaces of cities across the globe. In City Unsilenced: Urban Resistance and Public Space in the Age of Shrinking Democracy (Routledge, 2017), editors Jeffrey Hou of UW-Seattle and Sabine Knierbein of SKuOR, Vienna – both scholars of the dynamics of public space – have compiled the stories, strategies and theories derived from social movements in urban ...


Growth Without Displacement: A Test For Equity Planning In Portland, Lisa K. Bates Jan 2018

Growth Without Displacement: A Test For Equity Planning In Portland, Lisa K. Bates

Urban Studies and Planning Faculty Publications and Presentations

Portland, Oregon, is considered a pioneer of regionalism, integrated land-use and transportation planning, and sustainability as a criterion for planning policy. After four decades of land-use planning, Portland has a national and international reputation for urban livability and climate change mitigation. While these successes are laudable, in the past decade Portland’s underrepresented and underserved communities have been raising a voice to demand that planners address issues of income and racial inequality. In response to and in collaboration with communities, over the past five years Portland’s Bureau of Planning and Sustainability (BPS) has adopted an equity strategy with a ...


"Naturally Occurring" Or "Until Market Speculation Starts": Investigating The Precarity Of Affordable Rental Housing And The Potential For Displacement Along Planned Transit Lines, Lisa K. Bates Nov 2017

"Naturally Occurring" Or "Until Market Speculation Starts": Investigating The Precarity Of Affordable Rental Housing And The Potential For Displacement Along Planned Transit Lines, Lisa K. Bates

Urban Studies and Planning Faculty Publications and Presentations

New transit infrastructure is a double-edged sword for low-income renters: one the one hand, increased mobility supports access to jobs and critical services; but if transit-oriented development fails to include and preserve affordable housing, they may be pushed out by rising rents. The question of whether public investments spur gentrification and displacement have created intense controversy around planned transit extensions in our region. My research on precarious rental housing illuminates the specific mechanisms of housing displacement and challenges for housing affordability in the single-family/duplex and the large multifamily rental market. The loss of low-cost housing is occurring even without ...

NOAH sales show precariousness of this rental housing at a regional scale.

  • Active transactions of multifamily rental properties have been disproportionately NOAH. There have been over two thousand transactions of NOAH buildings in the Portland metro area from 2006 to 2017 — over 68,000 units of housing. These sales are accelerating, with over 20 percent occurring in just the last 18 months.
  • Sales prices for multifamily rental properties have increased substantially, making preservation of affordable rents more challenging. Regionally, the average sale price increased by 78 percent between 2010 and 2017; during this period there was a 43 percent increase ...

Towards Systematic Prediction Of Urban Heat Islands: Grounding Measurements, Assessing Modeling Techniques, Jackson Voelkel, Vivek Shandas

Urban Studies and Planning Faculty Publications and Presentations

While there exists extensive assessment of urban heat, we observe myriad methods for describing thermal distribution, factors that mediate temperatures, and potential impacts on urban populations. In addition, the limited spatial and temporal resolution of satellite-derived heat measurements may limit the capacity of decision makers to take effective actions for reducing mortalities in vulnerable populations whose locations require highly-refined measurements. Needed are high resolution spatial and temporal information for urban heat. In this study, we ask three questions: (1) how do urban heat islands vary throughout the day? (2) what statistical methods best explain the presence of temperatures at sub-meter ...

Do People’S Perceptions Of Neighborhood Bikeability Match “Reality”?, Liang Ma, Jennifer Dill Jan 2017

Do People’S Perceptions Of Neighborhood Bikeability Match “Reality”?, Liang Ma, Jennifer Dill

Urban Studies and Planning Faculty Publications and Presentations

Do people perceive the built environment the same as we objectively measure it? If not, what are the relative roles of the objective versus the perceived environment on bicycling behavior? This study, based on data from Portland, Oregon, explored the match or mismatch between the objective and perceived bicycling environment and how it affects people’s bicycling behavior. The descriptive analysis indicated a fair agreement between perceived and objective measures. Older adults, women having children, less-educated and lower-income persons, and those who bicycle less tended to perceive their high-bikeable environment (measured objectively) as being a low-bikeable environment. In addition to ...

While some contend that extensive public engagement activities are necessary to meet Health Impact Assessment (HIA) practice standards, other work suggests that an HIA of any type hasthe potential to inform decision-making in ways that embody HIA’s value of democracy (Cole & Fielding, 2007; Harris-Roxas et al., 2012; Negev, 2012). These divergent perspectives on how to realize democracy through public participation represents an area of evolving debate in the ongoing development of HIA practice in the US. Looking to the relatively diverse HIA practice on the west coast of the US, we explore the interplay between engagement strategies and HIA values in ...


Developing High-Resolution Descriptions Of Urban Heat Islands: A Public Health Imperative, Jackson Voelkel, Vivek Shandas, Brendon Haggerty Sep 2016

Developing High-Resolution Descriptions Of Urban Heat Islands: A Public Health Imperative, Jackson Voelkel, Vivek Shandas, Brendon Haggerty

Urban Studies and Planning Faculty Publications and Presentations

Extreme heat events affect the most vulnerable human populations and are a lethal health hazard to urban dwellers globally; in the United States, extreme heat causes more deaths annually than all other weather events and natural hazards combined (1). Previous studies described urban heat islands as isolated, static, monolithic areas of cities. We challenged this contention by hypothesizing that diurnal temperature cycles and diverse landscape features create variation in places that amplify heat (2). A temporal description of urban heat islands would identify populations that are susceptible to heat stress, particularly at night, when most people are asleep and unable ...

Reducing exposure to degraded air quality is essential for building healthy cities. Although air quality and population vary at fine spatial scales, current regulatory and public health frameworks assess human exposures using county- or city-scales. We build on a spatial analysis technique, dasymetric mapping, for allocating urban populations that, together with emerging fine-scale measurements of air pollution, addresses three objectives: (1) evaluate the role of spatial scale in estimating exposure; (2) identify urban communities that are disproportionately burdened by poor air quality; and (3) estimate reduction in mobile sources of pollutants due to local tree-planting efforts using nitrogen dioxide. Our ...

Recent evidence suggests that urban forms and materials can help to mediate temporal variation of microclimates and that landscape modifications can potentially reduce temperatures and increase accessibility to outdoor environments. To understand the relationship between urban form and temperature moderation, we examined the spatial and temporal variation of air temperature throughout one desert city—Doha, Qatar—by conducting vehicle traverses using highly resolved temperature and GPS data logs to determine spatial differences in summertime air temperatures. To help explain near-surface air temperatures using land cover variables, we employed three statistical approaches: Ordinary Least Squares (OLS), Regression Tree Analysis (RTA), and ...

Beyond The Screen: Uneven Geographies, Digital Labour, And The City Of Cognitive-Cultural Capitalism, Dillon Mahmoudi, Anthony M. Levenda

Urban Studies and Planning Faculty Publications and Presentations

In this paper, we demonstrate that an examination of the socio-environmental impacts of digital ICTs remains a fruitless enterprise without “materializing” digital labour. We suggest one approach to materializing digital labour: this first includes connecting political economic analyses of digital ICTs to the co-evolution and geography of planetary urbanization and technological change, and second, examining the relationships between immaterial, digital, labour with the material industrial production system. In the context of broad changes in technology, social life, and urbanization, many scholars have theorized a shift towards a third phase of capitalism, beyond mercantilism and industrialism, based in immaterial, digital, and ...

Urban Studies and Planning Faculty Publications and Presentations

This research aims to fill gaps in existing multi-modal performance measures for transportation and land use systems:

  1. As a supplement/replacement of traffic-centric measures such as LOS, travel delay;
  2. Recent federal and state legislations put more emphases on using of performance measures in transportation planning & operation: MAP-21, Oregon Job and Transportation Act (OJTA);
  3. Existing performance measures for transportation and land use systems, although now numerous, have their own limitation (Table 1), and leave important aspects and policy areas uncovered, for example, the balance of transportation investment between different modes and across geographical areas as mandated by OJTA

In recent years, much has been written on ‘big data’ in both the popular and academic press. After the hubristic declaration of the “end of theory” more nuanced arguments have emerged, suggesting that increasingly pervasive data collection and quantification may have significant implications for the social sciences, even if the social, scientific, political and economic agendas behind big data are less new than they are often portrayed. Compared to the boosterish tone of much of its press, academic critiques of big data have been relatively muted, often focusing on the continued importance of more traditional forms of domain knowledge and ...

Green Infrastructure (GI) is an increasingly popular means of dealing with flooding and water quality issues worldwide. This study examines public perceptions of, and behaviour around, bioswales, which are a popular GI facility in the United States. Bioswales are highly visible interventions requiring support from residents and policy-makers to be implemented and maintained appropriately. To understand how the residents’ perceptions and attitudes might develop over time, we interviewed residents of Portland, Oregon, living near bioswales installed 1–2, 4–5 and 8–9 years ago, to determine awareness, understanding, and opinions about the devices. We found no consistent patterns across ...

Transportation Leadership Education: Portland Traffic And Transportation Course A Case Study And Curriculum, Nathan Mcneil

Urban Studies and Planning Faculty Publications and Presentations

The Portland Traffic and Transportation course serves a number of different purposes. On one hand, it is designed to develop citizens who are informed about the transportation system, including how it got where it is today, what agencies and actors play a role in its operation and development, and how they, as citizens, play a role in its future. In this sense, there is a goal of broadening and deepening the existing knowledge about the system among the general population. On the other hand, there is an implicit goal of encouraging participation in the system with the understanding that doing ...

Throughout the history of cities, the ecological landscape has often been buried, removed, or taken for granted. A recent recognition that humans are part of the global ecosystem, and that human actions both cause and are affected by ecological change, brings with it an awareness of the value of nature in cities and of natural systems on which cities depend. The feedbacks between humans and their environment within an urban context can have profound implications for the growth of and change in cities, yet there is a limited understanding of the interactions between biophysical changes in cities and the implications ...


Overcoming Uncertainty And Barriers To Adoption Of Blue-Green Infrastructure For Urban Flood Risk Management, Colin R. Thorne, E. C. Lawson, Connie P. Ozawa, Samantha Hamlin, Leonard A. Smith Jan 2015

Overcoming Uncertainty And Barriers To Adoption Of Blue-Green Infrastructure For Urban Flood Risk Management, Colin R. Thorne, E. C. Lawson, Connie P. Ozawa, Samantha Hamlin, Leonard A. Smith

Urban Studies and Planning Faculty Publications and Presentations

Blue-Green Infrastructure (BGI) and Sustainable Drainage Systems (SuDS) are increasingly recognised as vital components of urban flood risk management. However, uncertainty regarding their hydrologic performance and lack of confidence concerning their public acceptability create concerns and challenges that limit their widespread adoption. This paper investigates barriers to implementation of BGI in Portland, Oregon, using the Relevant Dominant Uncertainty (RDU) approach. Two types of RDU are identified: scientific RDUs related to physical processes that affect infrastructure performance and service provision, and socio-political RDUs that reflect a lack of confidence in socio-political structures and public preferences for BGI. We find that socio-political ...
