EPSA is the largest neighborhood watch program in Los Angeles. The Association consist of 550 members.
Most subscribers are single family homes but apartment complexes and business also participate.
The purpose of EPSA is to support community based policing and promote programs which improve safety. EPSA works in partnership with SLO's to 'problem solve' and develop solutions to crime problems in the community. A community patrol service provides a licensed private patrol officer who patrols a specific neighborhood. The patrol officer cannot leave the dedicated patrol area and is equipped with a Nextel digital phone so subscribers can call the officer directly. The Community Patrol serves as the 'eyes and ears' of the community.
