To take HomeGrown StL to the streets, network members will conduct Catchment Area Pilots (CAPS) with the goal of improving the lives of 8,000 Black boys and young men ages 12 to 29. These pilot projects will first be implemented in a small number of St. Louis promise zone zip codes that are known to have great need for services. Findings will be used to develop a strategy to scale up for the region. The purpose of CAPs is to demonstrate the utility of a data-informed and placed-based model of comprehensive precision care and collaboration among service providers that is singularly focused on supporting the health, development, and upward mobility of young Black boys and men.
