Land Use Zoning In America: The Case For Inclusionary Policy, Thomas Geffner

Anthós

Residential zoning code has been one of the most powerful forces in shaping the growth of modern American cities. By regulating which types of buildings can go where, zoning code has led to the creation of suburbs as we know them, with row after row of detached single-family homes. Indeed, the American city would look drastically different if it were not for the creation of zoning codes. But how did the institution that is American zoning come to exist? This essay will attempt to answer that question by exploring the early history of zoning, starting in the 1910s. It will ...

Trip And Parking Generation At Transit-Oriented Developments, Reid Ewing, Guang Tian, Torrey Lyons, David Proffitt, Preston Stinger, Rachel Weinberger, Ben Kaufman, Kevin Shivley

TREC Final Reports

The decision of how best to allocate land around transit stations is a debated topic, with transit officials often opting for park-and-ride lots over active uses such as multifamily housing, office, and retail organized into transit-oriented developments (TODs). In practice, guidelines for providing parking and mitigating vehicle trips come mainly from the Institute of Transportation Engineers (ITE) Trip Generation Manual and the ITE Parking Generation Manual. However, both manuals have well-known shortcomings. The goal of this study is to determine how many fewer vehicle trips are generated at TODs, and how much less parking is required at TODs, than ITE ...

Citizen-Led Urban Agriculture And The Politics Of Spatial Reappropriation In Montreal, Quebec, Claire Emmanuelle Bach

Dissertations and Theses

Urban Agriculture (UA) has been practiced in Montreal, Quebec for well over a century. In the last five years or so, a renewed enthusiasm for UA has manifested itself in the form of citizen-led UA projects. The latter are often established in residual spaces, from vacant lots to sidewalks, and alleyways. These more spontaneous and informal UA practices point to a shift in how urban inhabitants perceive and use urban space. Through a case study of informal UA projects in Montreal, QC, this work brings attention to the dynamics surrounding the establishment of citizen-led UA projects, paying special attention to ...

Local Approaches To Regional Problems: Suburban Government Responses To Portland's Regional Housing Crisis, Emma Deppa

Dissertations and Theses

The Portland metropolitan region has seen unprecedented growth in the last three decades, resulting in both economic expansion and considerable gentrification. While lauded for its commitment to sustainability and a "smart development" ethos, many questions remain for the city with respect to the needs of displaced residents and a burgeoning population of young professionals. This study examines how various levels of government implement growth management policies to accommodate these demographic changes, and aims to assess whether and how the consequences of growth, especially gentrification and displacement, are meaningfully addressed. Qualitative interviews were conducted with staff members and elected officials from ...

The "Adam Cube" : Categorizing Portland, Oregon's Urbanization Using Gis And Spatial Statistics, Jeremy Grotbo

Dissertations and Theses

Transportation availability and land use intensity demonstrate a strong relationship, with intense development concentrated near significant transportation investment. Transportation networks evolved in response to emergent transportation technologies and changing urban land uses. The irregular distribution of transportation systems reinforced patterns of land use development, shaping urban form. Understanding the relationships between transportation and the intensity of land uses allows urban geographers and city planners to explain the urbanization processes, as well as to identify areas historically susceptible to future development. The goal of this research is to develop a quantitative framework for the analysis of the development of urban form ...

Cyclist Path Choices Through Shared Space Intersections In England, Allison Boyce Duncan

Dissertations and Theses

In the last several years, there has been growing worldwide interest in making streets safer for all users--pedestrians, cyclists, and motorists. One approach, shared space, is a traffic calming technique as well as urban design concept. This technique strives to fully integrate the roadway into the urban fabric by removing elements such as lane markings, curbs, and traffic signs. By removing these elements and creating a more plaza-like space, these sites become ambiguous and no user group as priority. The technique is relatively new, and the majority of existing research concerns pedestrians only. This mixed methods research focused on six ...

The Effects Of Urban Containment Policies On Commuting Patterns, Sung Moon Kwon

Dissertations and Theses

During the past several decades, most U.S. metropolitan areas have experienced strong suburbanization of housing and jobs (i.e., urban sprawl). The sprawl that arises from urban growth has become a big issue in many metropolitan areas in the U.S. In response, there has been increased interest in urban containment policies. There are contrasting views (planning-oriented vs. market-oriented) of urban sprawl and urban containment policies. Planning-oriented scholars asserted the problems of 'geographic sprawl (GS)' and the positive effects of urban containment polices, while market-oriented scholars asserted the problems of 'economic sprawl (ES)' and the negative or negligible effects ...

Sensible Air To Air Heat Recovery Strategies In A Passive House, Santiago Martin Rodriguez-Anderson

Dissertations and Theses

Due to rising energy costs and concerns about global climate change, high performance buildings are more in demand than ever before. With roughly 20% of the total energy consumption in the United States being devoted to residential use, this sector represents a significant opportunity for future savings. There are many guidelines and standards for reducing building energy consumption. One of the most stringent is the Passive House Standard. The standard requires that that air infiltration is less than or equal to 0.6 air changes per hour at a 50 Pascal pressure difference (ACH 50), annual heating energy is less ...

Whose Urban Forest? The Political Ecology Of Foraging Urban Nontimber Forest Products, Patrick T. Hurley, Marla R. Emery, Rebecca J. Mclain, Melissa R. Poe, Brain Grabbatin, Cari L. Goetcheus

Institute for Sustainable Solutions Publications and Presentations

Drawing on case studies of foraging in Philadelphia, Pennsylvania and Mt. Pleasant, South Carolina, we point to foraging landscapes and practices within diverse urban forest spaces. We examine these spaces in relation to U.S. conservation and development processes and the effects of management and governance on species valued by foragers. These case studies reveal the everyday landscapes of urban foraging and suggest that ideas about what constitutes the suite of appropriate human-environment interactions in the sustainable city are contested and accommodated in diverse ways.

Bicycle Level Of Service: Where Are The Gaps In Bicycle Flow Measures?, Pamela Christine Johnson

Dissertations and Theses

Bicycle use is increasing in many parts of the U.S. Local and regional governments have set ambitious bicycle mode share goals as part of their strategy to curb greenhouse gas emissions and relieve traffic congestion. In particular, Portland, Oregon has set a 25% mode share goal for 2030 (PBOT 2010). Currently bicycle mode share in Portland is 6.1% of all trips. Other cities and regional planning organizations are also setting ambitious bicycle mode share goals and increasing bicycle facilities and programs to encourage bicycling. Increases in bicycle mode share are being encouraged to increase. However, cities with higher-than-average ...

Participation, Information, Values, And Community Interests Within Health Impact Assessments, Nicole Iroz-Elardo

Dissertations and Theses

Health impact assessment (HIA) has emerged in the U.S. as one promising process to increase social and environmental justice through addressing health equity issues within planning. HIA practice is guided by values such as democracy and equity and grounded in broad social determinants of health. The most readily applied definition of democracy is problematic because it implies an element of direct, participatory engagement with the public. This is at odds with HIA practice that largely relies on stakeholder engagement strategies.

This dissertation critically examines the engagement strategies of three transportation planning HIA cases to more fully understand how the ...

Building And Maintaining Plankhouses At Two Villages On The Southern Northwest Coast Of North America, Emily Evelyn Shepard

Dissertations and Theses

Plankhouses were functionally and symbolically integral to Northwest Coast societies, as much of economic and social life was predicated on these dwellings. This thesis investigates both plankhouse architecture and the production of these dwellings. Studying plankhouse construction and maintenance provides information regarding everyday labor, landscape use outside of villages, organization of complex tasks, and resource management.

This thesis investigates three plankhouse structures at two sites, Meier and Cathlapotle, in the Lower Columbia River Region of the southern Northwest Coast of North America. Methods consisted of digitizing over 1,100 architectural features, creating detailed maps of architectural features, and conducting statistical ...

Hobbie, Kelli L. Larson, Jennifer L. Morse, Christopher Neill, Kristen C. Nelson, Jarlath O'Neil-Dunne, Laura A. Ogden, Diane E. Pataki, Colin Polsky, Rinku Roy Chowdhury

Environmental Science and Management Faculty Publications and Presentations

Earth's surface is rapidly urbanizing, resulting in dramatic changes in the abundance, distribution and character of surface water features in urban landscapes. However,the scope and consequences of surface water redistribution at broad spatialscales are not well understood. We hypothesized that urbanization would lead to convergent surface water abundance and distribution: in other words, cities will gain or lose water such that they become more similar to each other than are their surrounding natural landscapes. Using a database of more than 1 million water bodies and 1 million km of streams, we compared the surface water of 100 US ...

Impact Of Sustainable Cool Roof Technology On Building Energy Consumption, Prem Kiran Vuppuluri

Dissertations and Theses

Highly reflective roofing systems have been analyzed over several decades to evaluate their ability to meet sustainability goals, including reducing building energy consumption and mitigating the urban heat island. Studies have isolated and evaluated the effects of climate, surface reflectivity, and roof insulation on energy savings, thermal load mitigation and also ameliorating the urban heat island. Other sustainable roofing systems, like green-roofs and solar panels have been similarly evaluated. The motivation for the present study is twofold: the first goal is to present a method for simultaneous evaluation and inter-comparison of multiple roofing systems, and the second goal is to ...

Dissertations and Theses

The purpose of this study is to explore the use of integrated probe vehicle, traffic and land use data to identify and characterize fine particulate matter (PM[subscript 2.5]) hot spot locations on urban arterial corridors. In addition, a preliminary analysis is conducted to consider volatile organic compound (VOC) hot spot locations. A pollutant hot spot is defined as a location on a corridor in which the mean pollutant concentrations are consistently above the 85th percentile of pollutant concentrations when compared to all locations along the corridor. In order to collect data for this study, an electric vehicle was ...

Skateboarding As Transportation: Findings From An Exploratory Study, Tessa Walker

Dissertations and Theses

In recent decades skateboarding has expanded from recreation into a form of transportation. Skateboarders appear to use roadways much as other non‐motorized modes do. However, there is little academic research on the needs and characteristics of the skateboard as a mode. This research reports demographics, multi‐modal and travel behavior findings, and other data from an exploratory mixed‐methods study of skateboarding as a mode of transportation.

Diffusion Of Energy Efficient Technology In Commercial Buildings: An Analysis Of The Commercial Building Partnerships Program, Chrissi Argyro Antonopoulos

Dissertations and Theses

This study presents findings from survey and interview data investigating replication of green building measures by Commercial Building Partnership (CBP) partners that worked directly with the Pacific Northwest National Laboratory (PNNL). PNNL partnered directly with 12 organizations on new and retrofit construction projects, which represented approximately 28 percent of the entire U.S. Department of Energy (DOE) CBP program. Through a feedback survey mechanism, along with personal interviews, quantitative and qualitative data were gathered relating to replication efforts by each organization. These data were analyzed to provide insight into two primary research areas: 1) CBP partners' replication efforts of green ...

Evaluation Of Phase Change Materials For Cooling In A Super-Insulated Passive House, Jeffrey Stephen Lauck

Dissertations and Theses

Due to factors such as rising energy costs, diminishing resources, and climate change, the demand for high performance buildings is on the rise. As a result, several new building standards have emerged including the Passive House Standard, a rigorous energy-use standard based on a super-insulated and very tightly sealed building envelope. The standard requires that that air infiltration is less than or equal to 0.6 air changes per hour at a 50 Pascal pressure difference, annual heating energy is less than or equal to 15kWh/m2, and total annual source energy is less than or equal to 120 kWh ...

An Anthropology Of Urbanism: How People Make Places (And What Designers And Planners Might Learn From It), Brooke D. Wortham-Galvin

Institute for Sustainable Solutions Publications and Presentations

In their word play on what design praxis might succeed the New Urbanism movement in the United States, the July 2013 article “Newest Urbanism” in the Architect introduced to the uninitiated the concept of tactical urbanism. Defining tactical urbanism as "temporary, cheap, and usually grassroots interventions—including so-called guerrilla gardens, pop-up parks, food carts, and 'open streets' projects—that are designed to improve city life on a block-by-block, street-by-street basis," the article claims that it took this approach to shaping the city less than a decade to mainstream into the practices of US cities and firms alike. While Architect used ...

Faulty Measurements And Shaky Tools: An Exploration Into Hazus And The Seismic Vulnerabilities Of Portland, Or, Brittany Ann Brannon

Dissertations and Theses

Events or forces of nature with catastrophic consequences, or "natural disasters," have increased in both frequency and force due to climate change and increased urbanization in climate-sensitive areas. To create capacity to face these dangers, an entity must first quantify the threat and translate scientific knowledge on nature into comprehensible estimates of cost and loss. These estimates equip those at risk with knowledge to enact policy, formulate mitigation plans, raise awareness, and promote preparedness in light of potential destruction. Hazards-United States, or Hazus, is one such tool created by the federal government to estimate loss from a variety of threats ...

Neighborhood Commercial Corridor Change: Portland, Oregon 1990-2010, Kelly Ann Howsley-Glover

Dissertations and Theses

Commercial corridors in neighborhoods experiencing change have been relegated to a footnote in research on residential phenomena. It is taken for granted that the process of change experience by businesses within these neighborhoods mirrors that of the residential change. This assumption is often predicated on the underlying model of invasion succession, suggesting that inmovers displace native populations, whether they are residents or businesses. Analyzing time series data on neighborhood commercial corridor change, research attempted to first test data against the invasion succession model to see if it is an effective framework for analysis. Second, through comparison of case study areas ...

Measuring The Effects Of Environmental Certification On Residential Property Values - Evidence From Green Condominiums In Portland, U.S., Xi Yang

Dissertations and Theses

Green building, as an environmentally responsible and resource-efficient product, has emerged in recent decades. Along with the growing interest in green building design and operating practices, a number of green building certification standards and rating systems have been developed by different organizations worldwide. Those rating systems allow government regulators, building professionals, and consumers to embrace green building with confidence. Many recent studies find that LEED and Energy Star certified commercial buildings gain significant rental and sales price premiums and have higher occupancy rates. However, little research has been conducted to measure the market value of certified multi-family residential buildings, for ...
