Investigating Gentrification and the Role of Green Infrastructure

Increased human-centric requirements could turn the Leadership in Energy and Environmental Design program (LEED) into a sustainable development tool for cities through mitigation of gentrification. Green building rating systems, like LEED, were designed with environmental sustainability in mind. Sustainability holistically however is about preserving the environment, economics, and equity. A scoping literature review confirmed that LEED is used for energy efficiency and greening developments (preserving the environment). However, research also revealed that LEED has potential to mitigate gentrification (preserving economics and equity) if credits were adjusted, or the program was paired with policy, to have increased focus on affordability, maintaining local culture, and preventing resident displacement. Further conclusions based on literature could not be made due to a gap in research surrounding LEED programs and gentrification. Gentrification is a contemporary event that occurs from any type of land development; but more quantitative research surrounding gentrification-related variables could help guide LEED and policies towards what metrics would likely help reduce resident displacement. A longitudinal case study of Arlington County, Virginia paired with spatial modeling was performed with census-level data. The results demonstrated how LEED impacts onto gentrification-related variables could be measured. Accompanying census-level data with localized surveys in future studies could then provide more context to how gentrification impacts specific neighborhoods. This research establishes a methodological foundation for future studies to analyze these complex relationships between third-party green certification programs and gentrification. The code and related datasets for this study were uploaded to the Open Science Framework (OSF) (DOI 10.17605/OSF.IO/G3HCV) to help foster those next steps for not just other researchers in this space, but also localities. Localities, which currently utilize LEED and related programs in their development policies, could adapt this framework to help establish social and economic assistance programs to aid in making a more sustainable environment for residents without adjusting LEED itself.
