The Patrol Division is a 24-hour, 7-day a week, 365-day a year operation divided into two separate shifts. Each shift is assigned one sergeant, one corporal and seven or eight patrol officers. Each of the shifts has one or two Community Service Technicians, to handle the less serious calls, for service and ordinance violation enforcement. To supplement patrol shifts during peak activity periods, three officers are also assigned to "power shift" hours of 9:00 am to 5:00 pm or 5:00 pm to 3:00 am. The core responsibilities of the Patrol Division include 9-1-1-call response, preliminary investigation of reporting incidents, community service, law enforcement, crime prevention and community policing and problem solving.
