Busy Streets Theory: The Effects of Communityâ engaged Greening on Violence

Abstract

Lack of maintenance on vacant neighborhood lots is associated with higher levels of depression, anxiety, and stress for nearby residents. Overgrown grasses and dense brush provide hiding spots for criminals and space to conduct illicit activities. This study builds upon previous research by investigating greening programs that engage community members to conduct routine maintenance on vacant lots within their neighborhoods. The Clean & Green program is a communityâ based solution that facilitates residentâ driven routine maintenance of vacant lots in a midsized, Midwestern city. We use mixed effects regression to compare assault and violent crime counts on streets where vacant lot(s) are maintained by community members (NÂ =Â 216) versus streets where vacant lots were left alone (NÂ =Â 446) over a 5â year timeframe (2009â 2013). Street segments with vacant lots maintained through the Clean & Green program had nearly 40% fewer assaults and violent crimes than street segments with vacant, abandoned lots, which held across 4Â years with a large sample and efforts to test counterfactual explanations. Communityâ engaged greening programs may not only provide a solution to vacant lot maintenance, but also work as a crime prevention or reduction strategy. Engaging the community to maintain vacant lots in their neighborhood reduces costs and may increase the sustainability of the program.HighlightsBlighted and abandoned properties generate substantial costs and risk for postindustrial cities.Communityâ engaged maintenance of properties can reduce blight and increase social cohesion.We compare levels of crime on streets with â greenedâ versus unmaintained vacant lots.Community greened lots may reduce blight and crime at lower cost to cities and build social capital.
