911 Calls for CPD Service

What will you find here? 

When the Office of Emergency Management and Communications (OEMC) receives a 911 call, the dispatcher gathers information to form a clear understanding of the incident priority level. The information in these dashboards only includes service calls where a public safety unit was dispatched to the incident. Priority levels of calls are designated by 911 dispatchers at the OEMC. There are three main priority levels for calls resulting in a unit dispatch:

  • Level 1: Immediate Dispatch for life-threatening emergencies
  • Level 2: Rapid Dispatch for situations where timely public safety action has the potential to affect the outcome of an incident 
  • Level 3: Routine Dispatch when calls do not involve an immediate threat to life or bodily harm 

Some questions that this dataset can answer are: 

  • Which week in July 2020 had the highest number of Level 3 calls?
  • What types of calls typically require Rapid Dispatch? 
  • Which police district receives the highest number of Level 1 calls?
