The Citizen Radio Patrol Boundaries dataset describes areas with active citizen radio patrols. The Citizen Radio Patrol program was established in 1967 by a Detroit City Council Resolution and has become an essential part of the strength and safety of Detroit's neighborhoods. Community volunteers who participate in this program receive training from DPD and volunteer a small portion of their time each month to patrol their own neighborhood. Volunteers may serve as a patrol base operator, driver, or observer, roles that work together to observe and report any suspicious activity to the police. For more information on joining or creating a Radio Patrol area, please contact Myra Gracey at the office of Workplace & Community Resilience, Detroit Police Department 313-596-2520.
