Zone 2 (North Atlanta)
Zone 3 (Southeast Atlanta)
Zone 4 (Southwest Atlanta)
Zone 5 (Downtown-Midtown)
Zone 6 (East Atlanta)

9. “The Beats” : The Beat’s Defined Geographic Area.
The Beat Officer’s Expectations.
When the Beat is not busy, the Beat Officer may:
actively patrol the Beat;
look for problems to be addressed; and
talk with community members.
When the designated Beat is very busy, other officers may:
answer calls in the Beat, or
be assigned to the Beat.

10. “The Beats” : The Distribution of Beats. The Beats Design.
The Connection of Beats to Neighborhoods.
Resolving Problems within the Beats.
Assignment of officers to Beats.
3/25/2017

11. The Redistricting Process:
The basic process of redesigning the Zones and Beats included:
The evaluation of the Calls-for-Service (CFS) workload data; and
The formation of appropriate geographic areas with roughly equal demand for police service.
3/25/2017

12. The Redesign Process (Considerations):
Basing the Beats on the Zone boundaries;
The Zone and Beat Redesign Financial Projections;
The Zone Precincts’ Transfers;
The Redesign of the Beats and the Cost of the
Projected Project; and
Reallocating Infrastructure Expenses.
3/25/2017

13. Workload Measurements: The workload assessment for the Zone/Beat Redesign project was based on dispatched 911 calls for police service from July 2009 – June 2010.
The following calls are excluded from the measure:
Calls of an administrative nature
Officer initiated incidents
Incidents serviced by the Georgia State Patrol and other agencies
Cancelled calls for service
Calls with invalid latitude/longitude fields
Calls serviced by Tele- Serve
3/25/2017

14. Workload Measurements:
The calls were categorized by their initial call type (signal) and their final disposition code.
Every call in the categories received the same Workload Scores.
The Workload Scores were calculated, as follows:
Workload Calculation:
1. The call length was calculated.
2. The calls where more than one Officer was dispatched were multiplied.
The average call length was calculated.
Each call in a given category was assigned the average Workload Score.
3/25/2017

15. Workload Ratings:
The Workload Scores of all calls in the given Beat’s were summed, indicating that Beat’s total workload.
Each beat’s total Workload Score was then scaled into a standard Workload Rating .
The Workload Rating is a scale set such that a Beat with an average Workload Score would have a Rating of 100.
A Beat that has a Workload Rating of 120 has a workload 20% greater than average.
