The Coachella Police Department Investigations section conducts investigations on all cases with evidence possibly leading to the identity of the suspect or named suspects. Historically, Investigations units have been organized into two different divisions- Crimes Against Persons (Homicide, Robbery, Assaults, Sex Crimes, etc) and Crimes Against Property (Burglary, Grand Theft, Fraud and Forgery). In extremely large organizations, this system works well, but can lead to unequal caseloads and reduced effectiveness when a city is being hit hard by a particular crime type.


The Patrol Division for the Coachella Police Department covers an area of over thirty (30) square miles and serves a population of over 40,000 residents. The Coachella Police Department responds to over approximately 24,000 calls for service or approximately (79) calls for service daily.


The Coachella Police Department Contract consists of 32 sworn officer positions. Nineteen (19) of these positions are dedicated to the patrol division with the remaining officers dedicated to special assignments such as the Community Action Team (C.A.T.), School Resource Officers, along with Gang and Narcotics Enforcement.

Sworn supervision, Investigators and Administration further support the officer positions. Our Community Service Officers assist with the Community Oriented Policing ideology and needs, while supporting field services. Together, they are able to provide professional service to the citizens of Coachella.

Community Oriented Policing

The Coachella Police Department supports and promotes the concept of Community Oriented Policing. The Police Department prides itself in providing state of the art equipment and training to all its personnel so we can provide the best level of service to the citizens of Coachella.


All marked Coachella Police units conduct traffic enforcement as part of their duties.

Baseline services include staff to assist in complicated traffic investigations that occur within the City of Coachella. Depending on the severity, some collisions may be investigated by patrol officers or Community Service Officers (CSO). Major Injury Collisions, Fatal Traffic Collisions, or Injury Collisions with a suspected impaired driver involved often result in a supplemental response with at least one of the responding officers being a traffic accident investigator. They are regularly accompanied by Forensic Technicians. This multi-faceted response often results in the street or intersection where the collision occurred being closed for several hours. Public education is a main stay of the department. Public presentations at schools or community groups and address issues with a strong emphasis on improving traffic safety. We conduct annual public education events (Holiday Safety Program) and participates in regional and state enforcement activities. These includes the Office of Traffic Safety Sobriety/Drivers License Checkpoint and the Click It or Ticket seat belt enforcement programs, both being zero tolerance approaches to reduce injuries and deaths on our roadways related to traffic accidents.
