  Citation × Citation Citation Abstract Copy Title: Green Mind Gray Yard: Micro Scale Assessment of Ecosystem Services Author: Kirkpatrick, Erin Jolene Year: 2013 There is a spatial mismatch between the size of the area where people are living and the extent of land needed to ecologically support developed areas. More people are living in urban areas than any time in history, and the resources need to support cities have had to expand to try and meet the demands of increasing urban populations. However, areas of opportunity exist for urban areas to begin to positively contribute towards the available resources in a region. Because a large portion of urban areas is within private control, gaining a baseline understanding of how residents interact with ecosystem services served as basis of this study. Using a survey of residents in the Portland, OR area, correlations between demographic groups and questions regarding their beliefs, attitudes, and behaviors as they relate to vegetation proved that the knowledge of environmental relationships is an important first step in creating pro-environmental behavior. Those reporting a high level of knowledge for ecological system and processes were more likely to value the benefits of vegetation for other associated reasons, such as for recreational activities, aesthetic purposes, and air or water quality. Additionally, survey responses were mapped to spatial data to gain an understanding of the spatial characteristics of neighborhoods in the survey area and how they have changed over time. Overall, the results in the study display trends that can help outreach organizations and municipalities to determine plans to strategically engage the public in a way that could create a net gain in urban ecosystem services.

Year: 1981 Between 1845 and 1980 the Portland waterfront between southwest Washington and Clay Streets, east of Front Street, metamorphosed from wilderness to trade center, to highway, to inner-city vacant lot. No place in Portland has more graphically illustrated the rapidly changing forces of the modern age in which the city has grown. For much of its history this stretch of waterfront was mired in law suits. The struggles centered on public versus private ownership. Originally dedicated as public property, but left unimproved by the city, the waterfront was usurped by private investors. Eventually, private owners allowed their property to decay prompting the public to encourage improvements. The legal battles even became reversed as private investors sought to force the sale of the waterfront to the city. Through all the confusion of legal battles this stretch of waterfront played a central role in the development and identity of Portland. It has finally become, undisputed public territory. The tension and greed of private investment have been replaced by the lack of municipal funds for aesthetic improvement and have left this stretch of land, a potentially fine and important urban park, a vacant lot.

The Morrison-­Knudsen Corporation throughout the twentieth century represented one of the federal government's favored contractors. Following western reclamation projects, the U.S. federal government then used contractors to help move the U.S. economy out of the Depression, prepare for World War II, wage the Cold War at home and abroad, and win the space race. Thus, at key stages in United States history we observe the necessity of the U.S. federal government partnering with the heavy construction industry to achieve its policy objectives at home and abroad. Morrison-Knudsen was once the largest heavy contractor in the United States, participating in the construction of Hoover Dam, Pacific Naval Air Bases, Hanford Engineering Works, the U.S. Intercontinental Ballistic Missile System, and the Vehicle Assembly Building at the Kennedy Space Center.

  Citation × Citation Citation Abstract Copy Title: Identifying Clusters of Non-Farm Activity within Exclusive Farm Use Zones in the Northern Willamette Valley Author: Chun, Nicholas Year: 2017 This thesis provides an extensive look at where permitted non-farm uses and dwellings have clustered within Exclusive Farm Use (EFU) zones in the Northern Willamette Valley in Oregon. There is a looming concern that non-farm related uses and dwellings, or non-farm development, are conflicting with agricultural preservation strategies. Specifically, non-farm developments can potentially undermine the critical mass of farmland needed to keep the agricultural economy sustainable, but until now, studies have lacked spatially precise data to systematically track these phenomena. This thesis offers methodological contributions towards analyzing these operations and presents a broad account of what has been occurring in the region. Using permit approval data from the Department of Land Conservation and Development (DLCD) and 2015 county tax lot shapefiles, I geocoded the locations of these uses and dwellings. I used location quotient and spatial autocorrelation coefficients to identify non-farm hotspots in the region and summarized different typologies that have developed. The findings reveal that viticulture operations have amassed near Dundee and Newberg in Yamhill County, while commercial activities and home occupations have clustered near the Salem-Keizer UGB. Concurrently, dwellings have clustered near the Yamhill-Polk County border. Finally, I offer suggestions to improve Oregon's agricultural land use policy and data management process, as well as advocate for more intensive research in the future to generate narratives for our results.

  Citation × Citation Citation Abstract Copy Title: Continuous Data Integration for Land Use and Transportation Planning and Modeling Author: Wang, Liming, Kim, Kihong Year: 2014 There is an urgent need for improved models that address the interdependencies between land use and transportation, and considerable new work is underway to develop such models in Oregon and elsewhere. These models and planning practices to integrate land use into the process, however, require the integration of massive amounts of land use data that is messy and incomplete. There have been considerable advances in the treatment of such data problems in other domains, drawing on data mining and machine-learning techniques to address issues in various domains. To date, however, little systematic effort has applied these technological advances to the problem domain of land use and transportation data. Experience suggests that as much as 70% of the total effort in developing integrated land use and transportation models is directly or indirectly associated with data development, integration and cleaning, yet there is remarkably little systematic research focused on the development of reusable methods and tools to support this problem domain. In coordination with an ongoing project of similar theme funded by University of California Transportation Center (UCTC), this project will focus on bringing interdisciplinary methods to develop land use datasets for integrated land use and transportation planning and modeling, with special attention on preserving temporal dimension of the data and monitoring data quality through indicators. Utilizing statistics and machine-learning techniques, we will develop reusable tools that will create a harmonized and coherent land use database from various public and private sources. These tools will be made available to the public and can be used by cities, counties, metropolitan planning agencies, state agencies, universities or anyone else needing to develop a usable database for use in integrated planning and modeling. All of the resulting data, with the exception of proprietary or confidential input data where there is no viable alternative, would be public and reusable for planning and research.

  Citation × Citation Citation Abstract Copy Title: Evaluation of Transportation Microenvironments Through Assessment of Cyclysts' Exposure to Traffic-Related Particulate Matter Author: George, Linda A., Figliozzi, Miguel A., Monsere, Christopher M., Kendrick, Christine M., Bigazzi, Alexander Y, Moore, Adam Year: 2011 It is well established that vehicles powered by carbon-based fuels (e.g. gasoline, diesel) have a negative impact on air quality, especially in urban centers. Traditionally, air quality conformity studies analyze the macroenvironmental impact of transportation corridors, as they relate to regional air quality management concerns. Urban residents spend a considerable amount of outdoor time in transportation microenvironments as pedestrians, bicycle commuters, people waiting to use public transport, residents and workers situated along roadways, and commuters within vehicles. An emerging area of research has shown that human health impacts within transport microenvironments can be considerable, but have not been well-characterized. As urban public policies increasingly encourage the use of multi-mode commuting in dense urban centers, decisionmakers need reliable modeling tools to predict and mitigate the health consequences of vehicle-related emissions in transportation microenvironments. This project proposes unique integration of real-time multi-modal personal exposure monitoring with real-time detailed traffic monitoring in order to develop a computer model that links traffic characteristics, emissions, built environment configuration, mode of travel and health impacts. Existing emission and dispersion models do not take direct account of the dynamic nature of traffic and how emissions impact the health of the diversity of urban dwellers, bus commuters, pedestrians, and bicycle riders. Typical approaches use highly aggregated vehicle data and computed link speeds to assign an emission factor to the traffic, an assumed proportion of which is trucks. In addition, existing methods to assess environmental impacts tend to focus on the production source of the pollutant not the impacts, which require information on population activities and its proximity to vehicle flows. Personal exposure studies document significant air quality impacts within the transportation microenvironment but do not integrate dynamic traffic and emission analysis. Previous research argues for a comprehensive approach. From the perspective of mitigating transportation impacts, it is significant to understand: a) exposure to the pollution, which in turn requires assessment of where people are in relation to the source of the pollutant, and b) the relation between pollution and vehicle flows. This research will target highly polluted high exposure hotspots in Portland, e.g. high traffic flows running through a major trip destination area for shopping, entertainment, education, or health care highly dependent on mode of travel, traffic levels and type, and built environment characteristics. Our approach is to conduct field studies to measure personal exposure to particulate matter as a function of transportation mode through pre-determined routes in the city. Exposure levels, position, time and rate of travel will be recorded. Simultaneously we will collect detailed traffic data that will provide type/number of vehicle, speed of travel and start/stop behavior. GIS analysis of the urban form and land use characteristics will establish built environment parameters. These data will be integrated into a built environment-travel mode-exposure model. The major scientific innovations offered by this project are: 1) integration of detailed and real-time exposure/emissions with a real-time traffic measurement approach, and 2) development of an integrated emissions and transportation model that combines traffic characteristics, emissions, built environment configuration, mode of travel and predicted health impacts. The outcomes of the research will be of importance to the general public, urban communities, departments of transportation charged with managing urban traffic, and public health authorities.

  Citation × Citation Citation Abstract Copy Title: From Transit Stop to Urbanity Node: Field Audit for Measuring Livability at the Transit Stop Author: Ruggeri, Deni Year: 2013 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 their choice to use public transportation. The Eugene-Springfield metropolitan area and its transit system was the object of our investigation. Using Geographic Information System and Space Syntax software, we identified 17 bus stops having the most potential in terms of livability, which includes considerations of connectivity to other modes of transportation, mix of land uses surrounding the transit stop, and other traditional environmental qualities usually associated with sustainable places. The transit nodes were analyzed using an audit, a systematic test similar to those used by policymakers and communities to assess neighborhood walkability, which was expanded to include both quantitative and qualitative measures of livability. The effectiveness and wording of each type of question was carefully tested and refined, thanks to two separate pilot tests. The data collected through the audit was later standardized and merged into an index, a value representing the overall livability of the 17 bus stops audited. Despite minor differences across raters, the methodology proved effective in measuring and comparing livability across a variety of sites, and in illustrating their performance with regard to the environmental qualities tested.

  Citation × Citation Citation Abstract Copy Title: Toward a Spatial-Temporal Measure of Land-Use Mix Author: Gehrke, Steven R., Clifton, Kelly Year: 2015 Urban planning and public-health research has long been interested in the connection between land-use mix and travel. Interest from urban planners stems from the potential of transportation efficiency gains achieved by an increased land-use mix and subsequent shortening of trip lengths; whereas, public-health research advocates an increased land-use mix as an effective policy for facilitating greater physical activity. Yet, despite the transportation, land-use, and health benefits related to improving land-use mix and the extent of topical attention given by researchers, no consensus has been reached regarding the magnitude of its effect on travel. This absence of agreement may largely be attributed to the theoretical and methodological failings persistent in present attempts to accurately reflect land-use interaction and operationalize its quantification within a defined spatial extent. To better evaluate the impact of land-use mix on travel behavior and assess more temporal policies, a robust mix measure accounting for these two elements of land-use interaction and geographic scale as well as a temporal element of land-use mixing—missing from present specifications—must be introduced. This paper establishes the research agenda for a spatial-temporal land-use mix measure by (1) identifying the conceptual and methodological faults inherent to current land-use interaction and geographic-scale representations and (2) describing strategies and practical benefits of representing the temporal availability of land-use mixing in guiding innovative transportation/land-use policies.

  Citation × Citation Citation Abstract Copy Title: The Boulevard Study: From Arterial to Asset -- Examining the Role of the Multi-Way Boulevard in Coordinated Transportation and Land Use Planning Author: Gillem, Mark L. Year: 2010 Cities that were once considered the most-desired places to live or for businesses to locate are now seeking ways to unclog their increasingly congested roadways and regain their quality of life. U.S. Department of Transportation Strategic Plan Background Cities across the U.S. that are struggling with congestion resort to remedies that are increasingly difficult to implement. Adding capacity is a more challenging proposition given limited land availability, greater environmental constraints, and fiscal barriers. Replacing individual trips with transit has seen limited success and can typically only be justified at greater levels of density than many communities currently support. Multiway boulevards offer one possible but little studied alternative to congested arterials in metropolitan areas. These streets, which are common in Europe, have several lanes of faster moving through traffic in the middle separated by medians from parking and access lanes on the sides. With local traffic traveling in the slow moving access lanes, these streets support a wider array of land uses than typical arterials. Ground level retail uses can take advantage of on-street parking in the access lanes. Residential uses are attracted to the park-like quality of the landscaped boulevards. This study will investigate the transportation and land use potential of replacing the ubiquitous arterial with multiway boulevards. Objective. This is an applied research project that will examine the opportunities and constraints to converting an auto-oriented five-and six-lane arterial into a multiway boulevard with transit as a way of reducing congestion, improving pedestrian and automobile safety, and supporting more unified land uses. Hence, the study is well aligned with OTREC's theme of integrating land use and transportation planning as well as U.S. Department of Transportation (USDOT) strategic objectives focused on improving safety, enhancing mobility, and minimizing transportation related environmental impacts. Method and Scope The project will use a case study approach and will focus on the Franklin Corridor in the Eugene-Springfield area. Through a series of public workshops, planning studios, and student research efforts, University of Oregon graduate and undergraduate students in architecture, landscape architecture, and planning, along with local professionals, and members of the general public will work together to analyze existing conditions, develop planning objectives, prepare conceptual diagrams for development of the corridor, examine alternative right-of-way sections, and calculate potential future development capacities in terms of densities and open space. The work effort will be focused on developing a conceptual analysis of existing and proposed conditions rather than on detailed traffic modeling and design. The study area will include Franklin Boulevard from the eastern edge of Glenwood to Eugene's Ferry Street Bridge. The corridor is under intense development pressure. On the west end, Eugene's new Federal Courthouse will be the anchor for a 50-acre redeveloped industrial district. In the middle are proposals for the 80-acre Walnut Station Mixed Use Area. On the east end are redevelopment concepts for a 43-acre portion of Glenwood. In this project, we will look beyond these individual projects and study the potential for the corridor as a whole.

Considering investments in rail infrastructure have increased in recent decades (Bureau of Transportation Statistics, 2007; Israel & Cohen-Blankshtain, 2010), it is important for planners and researchers to understand how these rail systems influence land use, metropolitan development patterns, and population migration. The following paragraphs summarize the studies and their findings. The Effects of Commuter Rail Establishment on the Relationships between the Built Environment, Travel Behavior, and Residential Self- Selection (RSS): To help regional and transportation planners better understand the role that commuter rail plays in directing intra-regional development, this chapter provides a longitudinal investigation of the influence of commuter rail on surrounding neighborhoods’ RSS, travel behavior and the built environment. We first analyze the role of commuter rail establishment in influencing change in neighborhood-level demographics, housing and economics (signs of RSS), and travel behavior. Second, we compare surveyed commuter rail riders to residents of the commuter rail stations’ host and neighboring areas. The results indicate that the development of commuter rail does not alter the host tracts in any of the characteristics observed, but rather suppresses population growth in neighboring tracts. Paired with direct evidence from a commuter rail user survey, we conclude that the use of commuter rail is more likely influenced by the built environment than by RSS. The Effects of Commuter Rail Establishment on Population Deconcentration: Research to date has not established the efficacy of commuter rail systems in attracting migrants most likely to use such an amenity. Through the application of a modified population deconcentration model, this chapter finds that the provision of a commuter rail station significantly increases neighborhood-level out-commuting and gross migration, which signals success in attracting migrants requiring commuting infrastructure. These findings also signal that commuter rail encourages regional population deconcentration, but the evidence is insufficient to form a conclusion and the evidence from Chapters 2 and 4 signal otherwise. Developing an Agent-Based Model (ABM) For Estimation of Land Use Changes around Commuter Rail Stations over Time: This chapter improves the understanding of commuter rails’ effect on future land use changes through spatial interaction modeling. In particular, we develop an innovative agent-based model (ABM) that allows us to estimate and visualize the probability of land use changes per parcel based on proximity to commuter rail stations, freeway exits, and the region’s central business district. Briefly, this chapter concludes that the development of a commuter rail station is statistically significantly associated with decreases in single-family residential land use near the station, which is met by increases in multifamily and mixed-use development. The spatial effects of stations on individual land uses vary by land use type, and no generalizable area of influence could be established. This report points to potential future research, as well as implications for planning practitioners.
