- gentrification
- Gentrification can be a by-product of the process in which a disinvested, and possibly deteriorating, neighborhood undergoes revitalization through reinvestment in its physical assets. Gentrification can be controversial because it is often associated with an influx of higher-income residents, an increase in property values, and the displacement of at least some of the original lower-income residents.

- green infrastructure
- A strategically planned and managed network of wilderness, parks, greenways, conservation easements, and working lands with conservation value that supports native species, maintains natural ecological processes, sustains air and water resources, and contributes to the health and quality of life for America's communities and people. A green infrastructure network includes many types of lands including natural areas, parks, and green roofs. Green infrastructure can be used in urban areas to enhance wastewater and stormwater treatment, and be used in conjunction with traditional “hard” infrastructure like pipes and treatment facilities.
