Preservation of and reinvestment in the built environment as a redevelopment tool has been used by cities and towns across the country, in many cases providing significant social, economic and environmental benefits. Potential social effects have often been the least explored aspect of sustainable development, especially with regard to preservation, yet they are often the most challenging, particularly given the potential for displacement. This thesis reviews literature where the issues of preservation, redevelopment and sustainability intersect. A set of best practices was developed that can be applied to other cities and towns to help balance preservation- and equity- enhancing activities. Another result of this research is the development of appropriate community indicators to provide means for measuring the effects of preservation on social equity. A selection of the indicators will be applied to two selected case studies (Northampton and Pittsfield, MA) to explore how such indicators can work as a measurement tool, how to best adapt them for a community, and their comparative strengths and weaknesses. The findings section addresses the data at both the fine and coarse grain – for the indicators and best practices as well as for the overall observations from the study process.

This thesis identifies and explores the effects that new parking strategies and policies could have on transit-oriented development (TOD) success levels. Additionally, it makes the case for TOD parking regulation reform, and is designed to educate planners and stakeholders on how to successfully and responsibly shape parking regulation in the planning and implementation process, so that land use in the region allows the synergistic provision of sustainable transportation specifically to the Boston region. Transit-Oriented Development is viewed and defined differently throughout research and literature, with its most common traits being compact, mixed use development near transit facilities and high-quality walking environments. Due to automobile dependency in the United States, developments (including TOD) are required to provide a specific level of parking to accommodate automobile usage. Excessive provision of parking decreases urban density, walkability, housing affordability, and transit ridership. In order to comply with governmental regulations and still meet TOD goals and objectives, expensive measures such as parking garages are implemented to accommodate automobile users, leading to a less affordable development and smaller profit margins for developers. An assessment of land use characteristics around transit stations, literature pertaining to TOD and current parking regulations and policies is conducted. Best practices and strategies are proposed with the overall goal of decreasing automobile-dependency and its impacts on the urban environment. Due to TOD’s heavy reliance on extensive transit systems, the focus of the study is specifically on the 101 cities and towns in the Boston metropolitan region. Somerville, MA, which contains previous transit-oriented developments and future projects in the design process, is used as a case study for transit-oriented development.

This thesis explores three state-run green building programs (California, Minnesota and New York) through comparative case-study analysis. Main topics discussed include cost benefits, health benefits, certification (i.e. LEED or other), and lessons learned from direct interviews with program staff.
