St. Tammany Parish is divided into three districts for purposes of criminal enforcement. Under the districting plan, more ranking and experienced deputies are available in each district per shift. District commanders are able to set policies which affect the district while still maintaining the Sheriff's strategic vision for the parish. The majority of deputies work in the district in which they reside. Greater responsibility has been given to supervisors on a district level, effectively de-centralizing the chain of command.
The Patrol Division of the Sheriff's Office consists of over 200 deputies working in Districts II, III and IV (there is no district "I").
These deputies provide around the clock service to citizens answering calls and responding to complaints. When not specifically assigned to a call, these deputies spend their time patrolling the community. The deputies regularly patrol subdivisions and take time to visit with citizens. This allows for positive interaction between citizens and deputies and allows the deputy who works a certain area to hear concerns directly from the citizens who live in the area.
