A substation of the Poway Station, the 4S Ranch Substation was opened in November 2007.  The substation serves the 4S Ranch community, an unincorporated area surrounded by Rancho Bernardo, Rancho Santa Fe, Black Mountain Ranch, Rancho Peñasquitos and Lake Hodges.


Patrol deputies respond to calls for service, patrol the community, conduct preliminary investigations and aid the station detective with in-depth follow-up investigations, attend community events such as neighborhood watch meetings and make presentations to youth groups and schools.

All patrol deputies are trained in the C.O.P.P.S. (Community Oriented Policing and Problem Solving) philosophy and in partnership with area residents develop solutions to community and quality of life issues.


Detectives are responsible for investigating all general crime cases and arrests made by patrol deputies. Once a detective determines there is enough evidence to prove a specific person or persons committed a crime, an arrest can be made or the investigation could be forwarded to the San Diego County District Attorney’s Office for review and prosecution.
