Evaluation of the Contra Costa County Law Enforcement Assisted Diversion Plus Program

Interim Evaluation Report

Abstract

Launched in September 2017, the Contra Costa County Law Enforcement Assisted Diversion (CoCo LEAD Plus) program is a four-year initiative designed to divert and serve people with behavioral health needs who have been repeatedly arrested by the Antioch, California, police department for certain low-level nonviolent charges. With funding from the Contra Costa County Behavioral Health Division, the Urban Institute is conducting a mixed-methods evaluation of CoCo LEAD Plus consisting of (1) a process evaluation to document program implementation and operations, (2) an outcome evaluation to assess participants’ justice-related outcomes compared with those of similar people who are not diverted into services, and (3) a cost-benefit analysis to estimate the program’s cost effectiveness relative to business as usual. This report documents the program’s operations from September 2017 through March 2019, presents preliminary findings from the process and outcome evaluations, identifies strengths to build on, and proposes recommendations for program refinements.
