Community Policing Areas

As a part of the Field Operations Division, the Community Policing Unit's uniformed officers provide motorized patrol along with highly visible foot and bike patrol in neighborhoods. PST officers serve as a community policing mechanism by making personal contacts with area residents and merchants as well as providing a broad spectrum of proactive and preventive community services such as attending neighborhood meetings/block club development, security surveys, etc.
