This is a study of how a city planning staff worked together with a neighborhood group to develop a comprehensive plan for a neighborhood. It explores their relationship and the major conflicts that arise when they work together to develop a district plan.

The present thesis chronicles the decision to replace Portland, Oregon's Harbor Drive, a downtown highway located between Front A venue and the Willamette River, with Tom McCall Waterfront Park, a thirty-seven acre linear greenway, in the late 1960s and 1970s. These events provide an example of the battle against the ascendancy of the automobile and the ability of concerned citizen groups to affect city planning decisions.

Art is often used as a catalyst to stimulate redevelopment and neighborhood change. This often occurs inadvertently as the presence of artists in certain communities can attract both public and private investment to revalorize economically depressed areas. Marginal neighborhoods in inner-urban areas offer inspiration and diversity to artists seeking lower-cost housing. Their presence effectively makes these marginal communities "safe" for middle-class residents looking to live in a funky, urban neighborhood. Ultimately, however, artists are eventually priced out of the communities they helped to create. The Alberta district in northeast Portland, Oregon has used art to create an identity that distinguished it from other redeveloped neighborhoods throughout the city, having become known as the Alberta Arts District. The research presented in this thesis traces the history of the Alberta district from its roots as a thriving streetcar community through its years as a dilapidated, crime-ridden neighborhood, and into its current state as a vibrant arts district. I show how the commercial corridor along Alberta Street has evolved to reflect the changing demographic composition of the surrounding neighborhood. Additionally, housing in the surrounding residential neighborhood has experienced a dramatic increase in average sale price and an upfiltering of aesthetic appearance. Many are attracted to the Alberta district for its vibrancy and diversity, the people and businesses that contribute to the diverse atmosphere may disappear as real estate becomes increasingly more expensive.

Portland, Oregon, is considered to be a leader in sustainable development. Government agencies, nonprofit organizations, and businesses have been innovators in policymaking and practice that is aimed at creating a more sustainable city. Despite population aging, little is known about how or whether planners and developers consider older persons in terms of sustainable development. Thus, this study examined the case of sustainable, affordable housing developed for low-income adults aged 55 and older. Interviews with 31 key informants were conducted in order to answer three research questions: What is the meaning of sustainable development in Portland, Oregon, as it pertains to affordable housing for an aging society? How and why has sustainable, affordable housing for older adults been developed in Portland? What are the policies that affect the availability and appropriateness of sustainable, affordable housing for older adults in Portland? The sample included individuals who influenced the creation of senior housing (e.g., urban planners, architects, nonprofit directors) and who were identified either because of their roles within local housing development or through snowball sampling. Six Portland-area developments provided the context for studying how and why sustainable, affordable housing for older adults was planned and created in the city. The findings suggested that introducing the topic of aging into the discourse of sustainable development will lead to a more robust meaning of the concept, which can aid future research, policy, and practice. Five elements characterizing sustainable housing for older adults were identified: physical accessibility; proximity to community services; infrastructure that connects housing with services; healthy living environments; and high-quality social spaces in and near housing developments. The findings also pointed to the need for sustainable development practices to pay attention to social equity and the equitable distribution of affordable housing, including housing for older adults. Several insights into how sustainable, affordable housing for older adults developed in Portland were gained (e.g., using government subsidies; involving aging experts in integrated design processes; intersectoral partnerships that led to the city becoming an early adopter in greening its affordable housing), as well as why such housing was completed (e.g., there was a collective public-sector response to meet the need for creating sustainable, affordable housing; an emerging culture of sustainable development in Portland; urban and regional planning efforts have begun to address population aging). However, the amount of sustainable, affordable housing remains insufficient to meet Portland's aging population. Reasons identified include: the absence of specific housing policy attuned to the needs of older adults in Portland; disconnects between housing and health care and supportive services; and lack of integration of older adults in the planning, design, and development processes. Room for innovation and improvement exists in regard to healthy, accessible, green, and affordable housing policies and the development of new models of housing for an aging population. Based on this research, 10 guiding principles of sustainable development for an aging society were proposed to inform future research, as well as planning and development efforts.
