Oregon Property Tax Capitalization: Evidence From Portland, Jenny H. Liu, Jeff Renfro

Northwest Economic Research Center Publications and Reports

The passage of Measures 5 and 50 drastically changed the way property taxes were assessed in Oregon. The measures were intended to limit the ability of government to raise property taxes, while achieving other goals such as equalizing school funding across the state. The property tax system that resulted is complex and has introduced inequities into the system based on differing rates of changes between assessed value (AV) and real market value (RMV). The League of Oregon Cities (LOC) asked the Northwest Economic Research Center (NERC) to investigate the effect of the tax structure on residential sale prices as part …

More Urban Form, Fewer Auto Trips, Kelly J. Clifton

TREC Project Briefs

Trip generation refers to the number of vehicle trips that are predicted to originate in a given zone. The Institute of Transportation Engineers (ITE) publishes standard trip generation rates for various land use types, but these rates are primarily measured in low-density suburban areas. There is national interest in building data that expands upon the existing ITE trip generation rates to include sites located in a multi-modal context.

In areas that have a more compact urban form, better access to transit and a greater mix of land uses, fewer vehicle trips may be generated there than ITE rates indicate. However, …

Radical, Reformist, And Garden-Variety Neoliberal: Coming To Terms With Urban Agriculture’S Contradictions, Nathan Mcclintock

Urban Studies and Planning Faculty Publications and Presentations

For many activists and scholars, urban agriculture in the Global North has become synonymous with sustainable food systems, standing in opposition to the dominant industrial agri-food system. At the same time, critical social scientists increasingly argue that urban agriculture programmes, by filling the void left by the "rolling back" of the social safety net, underwrite neoliberalisation. I argue that such contradictions are central to urban agriculture. Drawing on existing literature and fieldwork in Oakland, CA, I explain how urban agriculture arises from a protective counter-movement, while at the same time entrenching the neoliberal organisation of contemporary urban political economies through …

Wave Energy In Clatsop County, Or: An Economic Impact Analysis, Jeff Renfro, Janai Kessi, Ayesha Khalid, Kyle O'Brien

Northwest Economic Research Center Publications and Reports

This study analyzes the economic impacts of building a wave energy commercial generation project in Clatsop County, Oregon. The modeled project is relatively small, and was produced by reviewing relevant wave energy literature and working with two local wave energy developers to estimate the expenditures and related costs of the project. We find that the construction and ongoing operation of a commercial wave energy project would create gains in employment, income, and output in the area as well as preparing Astoria for further wave energy development.

How Well Has Land-Use Planning Worked Under Different Governance Regimes? A Case Study In The Portland, Or-Vancouver, Wa Metropolitan Area, Usa, Jeffrey D. Kline, Paul R. Thiers, Connie P. Ozawa, J. Alan Yeakley, Sean N. Gordon

Urban Studies and Planning Faculty Publications and Presentations

We examine land use planning outcomes over a 30-year period in the Portland, OR-Vancouver, WA (USA) metropolitan area. The four-county study region enables comparisons between three Oregon counties subject to Oregon’s 1973 Land Use Act (Senate Bill 100) and Clark County, WA which implemented land use planning under Washington’s 1990 Growth Management Act. We describe county-level historical land uses from the mid-1970s to the mid-2000s, including low-density residential and urban development, both outside and inside of current urban growth boundaries. We use difference-in-differences models to test whether differences in the proportions of developed land resulting from implementation of urban growth …

Multiday Gps Travel Behavior Data For Travel Analysis: The Effect Of Day-To-Day Travel Time Variability On Auto Travel Choices, Jennifer Dill, Joseph Broach, Kate Deutsch-Burgne, Yanzhi Xu, Randall Guensler, David Levinson, Wenyun Tang

Urban Studies and Planning Faculty Publications and Presentations

This project explored the potential of archived multi-day GPS data to expand the understanding of travel-time reliability. While reliability is often observed and considered at the system or segment level, travel-time uncertainty is also experienced at the household and trip level. Any move toward incorporating reliability into regional travel models will necessitate a re-examination of travel-time variation at more disaggregate levels. The analysis uses multiday vehicle-based GPS data analyzed within the Transportation Secure Data Center (TSDC). There were three major goals for the research. The first goal was to consider the ways in which multiday GPS data could be translated …

Race, Segregation, And Choice: Race And Ethnicity In Choice Neighborhoods Initiative Applicant Neighborhoods, 2010–2012, Matthew F. Gebhardt

Urban Studies and Planning Faculty Publications and Presentations

During the past two decades, concern about spatial concentrations of poverty and disadvantage has become an ascendant scholarly and policy issue, and research on the effect of neighborhoods on individual and family life chances has grown substantially. The Choice Neighborhoods Initiative (hereafter, Choice), introduced in 2009, is a new federal program designed to address concentrated poverty. Choice, which is functionally the successor to the Housing Opportunities for People Everywhere, or HOPE VI, Program, provides competitive grants to fund redevelopment and revitalization in neighborhoods that have concentrations of poverty and publicly subsidized housing, with the goal of transforming them into neighborhoods …

Union Carpenter Activity Forecasting, Thomas Potiowsky, Kyle O'Brien, Jeff Renfro

Northwest Economic Research Center Publications and Reports

The objective of this study is to obtain a model and methodology for forecasting carpenter activity for the purpose of forecasting Trust contributions. Employer contributions into the trust are a function of hours worked by carpenter union members. Therefore, by forecasting the hours worked by carpenters, the Trust can easily obtain an estimate for employer contributions.

Getting Your House In Order: A Model For African-American Financial Education, Lisa K. Bates, Stacey Triplett

Urban Studies and Planning Faculty Publications and Presentations

The Portland Housing Center (PHC) is a national leader in educating and creating first time homebuyers, with outreach efforts that bring diverse households to its services. However, in 2010, PHC recognized that African American customers were much less likely to buy homes, even when they received counseling. The Portland (OR) area’s African American homeownership rate was just 35% (compared to 65% for Whites) and actually declined from 2000 to 2010.

Working with an African American advisory committee and with research guiding development, implementation, and evaluation, PHC developed a comprehensive program around outreach and services to African Americans in the Portland …

Transit Justice For Youth In Multnomah County, Oregon: A For Youth By Youth Report, Lisa K. Bates

Urban Studies and Planning Faculty Publications and Presentations

In May 2014, the MYC hosted young people at our first Youth Summit for Transit Justice. In this youth-led process, we brought together youth from across the county and adult policy-makers to address our region’s transit issues. It was an important step for building youth-adult partnership to improve transit access for young people in Multnomah County. In this report, we report on the Transit Justice Summit and the youth perspective on transit fares, access, and the importance of transit justice for the success of all youth in Portland and Multnomah County. This report was created from research we conducted to …

How Livable Is Your Transit System?, Marc Schlossberg

TREC Project Briefs

The U.S. Department of Housing and Urban Development has identified some “livability principles” which include healthy, safe and walkable neighborhoods and safe, reliable and economical transportation choices. Transit agencies and local governments routinely use metrics to evaluate the performance of transit systems, but a uniform standard of transit data collection does not exist outside of the reporting requirements of the National Transit Database (NTD). Because of the types of data collected for the NTD, the focus of performance measurements is often on ridership and financial performance, leaving aside the question of livability.

In an OTREC-sponsored project, principal investigator Marc Schlossberg …

A Comparison Of Emergency Service Provider Costs For Formerly Homeless Persons Living Inpermanent Supportive Housing In Washington County, Oregon, Scott Stewart, Janai Kessi

Northwest Economic Research Center Publications and Reports

This essay argues that cities can also be front and center as vividly imagined worlds whose characteristics play active roles that help to structure the arc of the story, forcing and constraining the choices that the characters make.

Cracking Susceptibility Of Concrete Made With Recycled Concrete Aggregate, O. Burkan Isgor, Jason Ideker, Tengfei Fu, Matthew P. Adams

TREC Final Reports

As high-quality, local, natural aggregate resources continue to become less available, and the cost of landfilling waste material rises, the need for alternative aggregates and recycling of waste material will increase. Using RCA in fresh concrete is one way to address both of these issues. However, there has long been a concern that RCA may negatively affect the properties of new concrete in which it is included. The results of the present investigation, however, indicate that the use of RCA in new concrete may not produce higher levels of free drying shrinkage as previously believed. Actually, these results show that …

From Transit Stop To Urbanity Node: Field Audit For Measuring Livability At The Transit Stop, Deni Ruggeri

TREC Final Reports

This research proposal addresses issues of livability at the transit stop. American transit systems have historically been “shoehorned” into existing street networks designed predominantly for cars and trucks. While much research exists on livability and walkability in the context of urban and suburban streets and blocks, bus stops are greatly understudied. This research focused on bus stops and aimed at analyzing their performance in terms of livability, with particular emphasis on perceptions. Our definition of livability was expanded to include considerations of safety and maintenance, cleanliness, imageability and vitality, which have been shown to affect people’s perceptions of livability and …

Using Indicators Projects As Prompts For Exploring Equity: A Case Study Of Greater Portland Pulse, Meg Merrick, Diane Besser, Shelia A. Martin

Institute of Metropolitan Studies Publications

This paper describes the process that the Greater Portland Pulse (GPP) initiated to incorporate the measurement of progress toward social equity into the project. While equity may appear to be a widely accepted priority for communities, the GPP process created a dialogue that was sometimes contentious but also profoundly educational for the participants revealing some of the complexities, not only of the issue of equity, but the challenges (particularly the inadequacy of available data) and trade-offs that are inescapable when using conventional data sets.

Additionally, this paper discusses some of the consequences of a process that, while incorporating equity values …

Action Plan For An Age-Friendly Portland, The Age-Friendly Portland Advisory Council

Institute on Aging Publications

The goal of this Action Plan is to enhance Portland, Oregon’s age friendliness. As defined by the World Health Organization (WHO), an "age friendly" city:

• has structures and services that are accessible and inclusive of older people with varying needs and capacities
• emphasizes enablement rather than disablement, and
• is friendly for people of all ages and abilities

The action steps that comprise this plan are intended to move Portland toward future development and activities that foster not only physical environments but also social and service environments that meet these criteria, making Portland a community for all ages.

2012 Portland Metropolitan Region Transportation System Performance Report, Robert L. Bertini, Dean George, Matthew Downey

Civil and Environmental Engineering Faculty Publications and Presentations

Our transportation system is a key ingredient in the economy, quality of life and urban fabric of the Portland metropolitan area. It has been stated in the past that it is not possible to manage our transportation system tomorrow unless we understand how it is performing today. In this spirit, Portland State University has been working with regional and statewide partners to develop new capabilities to measure, monitor and track the performance of the transportation system in real time and using archived data sources. We believe that it is possible to leverage these disparate data sources toward providing better transportation …

Durability Assessment Of Recycled Concrete Aggregates For Use In New Concrete: Phase I - Revised, Jason H. Ideker, Matthew P. Adams, Jennifer Tanner, Angela Jones

TREC Final Reports

The primary goal of this research project was to investigate the long-term durability of concrete incorporating recycled concrete aggregate (RCA) through accelerated laboratory testing. Overall it was found that modifications to standard aggregate testing and characterization standards were necessary for testing RCA. This included modifications to standard tests including ASTM C 128, C 305 and C 1260. It was found that the potential for alkalisilica reactivity did exist for new concrete containing RCA. The characteristics of the RCA also had a profound effect on ASR related expansion. RCA with a higher content of reactive coarse or fine aggregate (compared to …

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 the term …

Modeling Of Dc Link Capacitor Current Ripple For Electric Vehicle Traction Converter, Lei Jin, Julia Zhang

TREC Final Reports

Contemporary Full Hybrid Electric Vehicle/Plug-in Hybrid Electric Vehicle/Battery Electric Vehicle (FHEV/PHEV/BEV) products use one or more DC/AC power converters, also known as traction inverters, to convert the DC voltage/current provided by the traction battery to the AC voltage/current to drive the traction motor(s). Large and bulky DC link capacitors are used at the input of the traction inverter to provide a smooth DC input voltage. Those DC link capacitors, occupying almost 50% of the space in the whole package, can contribute to more than 20% of the total cost of the traction inverter. They are generally over designed to assure …

Improving The Representation Of The Pedestrian Environment In Travel Demand Models, Phase I, Kelly J. Clifton, Patrick Allen Singleton, Christopher Devlin Muhs, Robert J. Schneider, Peter Lagerwey

Civil and Environmental Engineering Faculty Publications and Presentations

There is growing support for improvements to the quality of the walking environment, including more investments to promote pedestrian travel. Metropolitan planning organizations (MPOs) are improving regional travel demand forecasting models to better represent walking and bicycling and to expand the evaluative capacity of models to address policy-relevant issues like air quality, public health, and the smart allocation of infrastructure and other resources. This report describes an innovative, spatially disaggregate method to integrate walking activity into trip-based travel models. Using data for the Portland, OR, metropolitan area, the method applies trip generation at a new micro-scale spatial unit: a 264-foot-by-264-foot …

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 …

Contesting Sustainability: Bikes, Race, And Politics In Portlandia, Amy Lubitow, Thaddeus R. Miller

Urban Studies and Planning Faculty Publications and Presentations

Despite decade old calls for a "just sustainability," urban sustainability policy and practice remains oriented toward environmental outcomes and eco-lifestyle projects. Notions of equity, justice, and inclusion continue to be marginalized in favor of technological solutions, such as green buildings, that are visible, easy to implement, and help to promote economic development. By examining a controversy over a bikeway development project in a rapidly gentrifying neighborhood in Northeast Portland, Oregon, this article explores how despite apolitical appeals to broadly shared values or visions of what a sustainable city ought to look like, sustainability projects can be—and perhaps should be—hotly contested. …

Overlooked Destinations: Suburban Nodes, Centers, And Trips To Strips, Nico Larco, Robert Parker

TREC Final Reports

This study looks at travel to typical suburban commercial strips by residents living within one-third of a mile of the strip by focusing on six sites – four in the Portland, OR., metro area and two in the Atlanta, GA., metro area. The study mapped pedsheds around the commercial strips in these sites and found significant increases in network extents when formal and informal pedestrian paths were added to street centerline data. Informal networks such as goat paths through vacant land and cuts in fences were widespread and suggest a pent-up demand for route directness. Travel surveys of residents found …
