The Effect of Removing Blighted Property on 311 Calls for Non-Emergency Services

Previous studies have linked collective efficacy within communities to positive health outcomes, reduced violence, and stronger communal values. A recent study featuring PISC Past Trainee Christopher Morrison, PhD, Senior Scholar Sara Jacoby, PhD, MPH, RN, Senior Scholar Michelle Kondo, PhD, and Charles Branas, PhD, examines the effect remediation of blighted properties has on collective efficacy. Non-emergency 311 calls were used to measure collective efficacy. 812 vacant lots in New Orleans were assessed, 203 of which had undergone remediation. Results indicated a significant increase in calls relating to dumping and garbage in areas surrounding remediated lots. This implies that blighted property remediation could have an effect on dumping and garbage. Further analysis of variations in 311 calls is necessary to understand the full impact of blighted properties on of collective efficacy.
