As a city grows, the population flows out of the urbanized area and forms a suburban settlement. These settlements are often auto-centric and contain big blocks with low walkability and limited accessibility to daily destinations which are geographically dominated by post-World War development. This type of development is referred to as urban sprawl (Dunham-Jones & Williamson, 2011). Urban sprawl decreases accessibility to jobs and amenities, separates different land uses, and increases car dependency, thus negatively impacting the environment, society, and the economy. Sprawl retrofitting has received a great deal of attention as a response to sprawl. It modifies the suburban environment through design approaches and aims for a mixed-land use, walkable neighborhood. Several studies have examined changes related to urban sprawl and sprawl retrofitting. However, not many studies have examined the urban form and sociodemographic changes resulting from those redevelopment projects before and after implementation. This study explores neighborhoods that have experienced urban sprawl retrofitting projects to understand their impact on urban form and socio-demographic structure. First, this study identifies 59 sprawl retrofitting projects in the United States. Projects are mainly collected from online sources (e.g., Traditional Neighborhood Development and Congress of New Urbanism websites) and relevant literature (e.g., Retrofitting Suburbia by Ellen Dunham-Jones, The Sprawl Repair Manual by Galina Tachieva, etc.). The criteria used to define a sprawl retrofitting case are: 1) projects should have a previous use (in other words, not vacant or undeveloped), 2) the new development must have a mix of uses (e.g., public housing redevelopment projects are excluded if they remained residential-only communities), and 3) to compare sociodemographic changes before and after the project-we limited our cases to those completed between 2000 and 2016-aligned with Decennial Census 2000 and ACS 2014-2018.After compiling and mapping a list of sprawl retrofitting projects, urban form and socio-demographic changes are analyzed before and after the projects. A case-control design methodology was used to analyze and interpret the data. Demographic and employment data are collected from the American Community Survey (ACS) 2014-2018 estimates and Longitudinal Employer-Household Dynamics (LEHD) database (2002 and 2017). The analysis is built upon an inventory of sprawl retrofitting projects that provide researchers and practitioners a foundation for future research. Some of this study's findings include increased population and job density, increase in gross rent, housing value and household income, and an increase in population with bachelor's degrees and non-Hispanic white people in the sprawl retrofitting neighborhoods. Some implications of the comparison of changes can be gentrification and displacement of specific demographics in sprawl retrofitting neighborhoods. Regarding transportation outcomes, the percentage of walking and transit compared to commuting has decreased in projects that do not abide with the sustainable transportation goals. This implies the existing growth and development pattern that necessitates automobile use and the failure to provide accessibility in daily travels. The other purpose of this study is to compare changes in urban form. Selected variables are average block size, intersection density, and percentage of green space. This study found that average block size has decreased, and intersection density has increased. Green space percentage did not change significantly and was inconsistent among sprawl retrofitting projects. This study attempts to reveal the changes and provide a comparison of selected variables that can inform planners and designers about the consequences of current retrofitting practices and help re-examine the methods and criteria of their projects.
