1 The Atlanta Police Department
2010 Zone and Beat Redesign Overview 3/25/2017

2 The Objective: Chief Turner has charged
The Field Operations Division and The Planning and Research/ Accreditation Unit to: Analyze the Patrol Beats and Zones for the purpose of determining current workload distribution; and Redesign the Beats and Zones where necessary to balance workload distribution and improves service delivery. 3/25/2017

3 The Objective: - Zone and Beat Redesign - Resource Determination
The Atlanta Police Department formed a Zone and Beat Redesign Committee. The Analytical and Management issues are: - Resource Allocation - Zone and Beat Redesign - Resource Determination 3/25/2017

4 Resource Allocation: The Department can and should:
Allocate its call-answering personnel to the Zones and to the watches : - the allocation should be in proportion to the patrol workload. 3/25/2017

5 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. 3/25/2017

6 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. 3/25/2017

7 The Zones are organized as follows:
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-Precincts 3/25/2017

8 The Introduction: Patrol Zones: “The 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) 3/25/2017

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. 3/25/2017

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. 3/25/2017

16 Current Zones and Beats
Number of Beats Area (Mi2) Workload Rating Above/Below Average Zone 1 11 18.6 1023 -7.0% Zone 2 10 36.1 898 -18.3% Zone 3 12 21.0 1191 8.3% Zone 4 32.8 1274 15.9% Zone 5 8.2 1251 13.7% Zone 6 16.7 963 -12.5% The Targeted Workload Rating Per Zone is 1100 3/25/2017

17 Current Beat Workload Distribution
(The City is currently divided into 66 beats of varying sizes.) The following is based on the calculation of the Workload Ratings for each beat: Above Average Beats Below Average Beats Beat Workload Rating 408 187 303 160 204 159 501 151 508 140 413 138 506 134 410 131 412 130 Beat Workload Rating 201 23 504 46 312 47 601 52 605 202 53 110 55 606 60 108 66

19 The Zone and Beat Redesign Plan

20 The Zone and Beat Redesign Plan
The Plan is elucidated below: “Zones and Beats Redesigned with Additional Beats Added”: The Department can Redesign the Beats and Zone and add 12 more Beats . 3/25/2017

21 More Officers per square mile;
“Zones and Beats Redesigned with Additional Beats Added” Summary: Re-designs the Beats to a 78 Beat plan; and Re-designs the Zones so that all six Zones have new Beats. Benefits: More Officers per square mile; Reduces disparity in Beat workloads; Equalizes Zone workloads; and Improves response times anticipated. Disadvantages: Analytical crime comparisons with previous years, more difficult ; and Some neighborhoods change Zones. Challenges: The Mandatory 8 week foot beat detail. 3/25/2017
