- Resource Allocation- Zone and Beat

Redesign - Resource

Determination04/10/23

Resource Allocation:

The Department can and should:

1.Allocate its call-answering personnel to the Zones and to the watches :

Zone and Beat Redesign :

Chief Turner has also charged the Zone and Beat Redesigning

Committee with:

• Analyzing the patterns of calls for service; and

• Re-drawing Zone and Beat lines. 04/10/23

Resource Determination:The Zone and Beat Redesign Committee has:

• Analyzed its Calls-for-Service (CFS) workload;

• Evaluated the response times to high priority calls;

• Assessed the officers’ available time for community

policing and other proactive work; and

• Analyzed other factors, i.e. natural boundaries, interstates, railroad lines.04/10/23

The Introduction:“The Zones”

The Zones are organized as follows:

• Mobile Operations  

• Investigations

• Field Investigation Team (FIT) and the Zone Discretionary Unit (ZDU)

• Foot Patrol Units 

• Mini-Precincts04/10/23

The Introduction: “The Zones”

Patrol Zones:• Zone 1 (West Atlanta)• Zone 2 (North Atlanta)• Zone 3 (Southeast Atlanta)• Zone 4 (Southwest Atlanta)• Zone 5 (Downtown-Midtown)• Zone 6 (East Atlanta)

“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.04/10/23

“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.

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. 04/10/23

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.  04/10/23

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- Serve04/10/23

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.3. The average call length was calculated.4. Each call in a given category was assigned the average Workload

Score.

04/10/23

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.
