City of Morgan Hill Public Safety Master Plan

 About 500 events (2 percent) involved patrol units spending zero time on scene.

 Approximately 12 percent of other-initiated calls lacked any recorded arrival time. We used the remaining calls when measuring the department’s overall response times.  The computer-aided dispatch (CAD) system used approximately 130 different event descriptions, which we condensed to 15 categories for our tables and 9 categories for our figures (shown in Chart 8-1). Table 8-20 in the appendix shows how each call description was categorized. Between January 1, 2015, and December 31, 2015, the communications center recorded approximately 26,700 events that were assigned call numbers and which included an adequate record of a responding patrol unit as either the primary or secondary unit. When measured daily, the department reported an average of 73 patrol-related events per day, approximately 2 percent of which (1.5 per day) had fewer than 30 seconds spent on the call. In the following pages we show two types of data: activity and workload. The activity levels are measured by the average number of calls per day, broken down by the type and origin of the calls and categorized by the nature of the calls (crime, traffic, etc.). Workloads are measured in average work-hours per day.
