DRP Programs
Integrated Substance Use Disorder Treatment (ISUDT)–Overview
On January 21, 2020, the California Department of Corrections and Rehabilitation (CDCR) and California Correctional Health Care Services (CCHCS) implemented ISUDT.  ISUDT is a comprehensive and evidence-based cross-divisional program with pathways to treatment through DRP Cognitive Behavioral Interventions (CBI) programs referred to as:

CBI-Intensive Outpatient (Medical Classification T1, SOMS assignment code ISI) 2-hours/day, 5-days/week, 52-weeks completion

CBI-Outpatient  (Medical Classification T2, SOMS assignment code ISO) 2-hours/day, 3-days/week, 14-weeks completion

CBI-Life Skills (Medical Classification T3, SOMS assignment code CB2) 2-hours/day, 3-days/week, 29-weeks completion

All participants will be assessed by medical and referred to one of the CBI classes.


The primary mission of the Sierra Conservation Center (SCC) is to provide housing, programs and services for minimum and medium custody inmates, to aid in their rehabilitation. SCC is also responsible for the training and placement of male inmates in the Conservation Camp Program.

SCC functions as the center for training staff and inmates in firefighting techniques for the southern portion of California. The institution is separated into two dormitory type facilities for minimum and low-medium custody inmates and one 270 Design Facility with celled housing for high-medium custody inmates.

Each of the 16 Conservation Camps is a self-contained “prison without walls.” The camps are sited in rural or wilderness areas for fire suppression. Inmates assigned to camps are dispatched to fight wild land fires and other emergencies when needed and a variety of community work projects. This results in a tremendous cost savings to tax payers of the State of California.

SCC houses inmates designated by medical as low to medium risk, and identified by the Mental Health Services Delivery System as Correctional Clinical Case Management System or lower. Inmates at SCC are encouraged to attend education programs that include Adult Basic Education, General Educational Development programs, Career Technical Education in Computer Literacy, Building Maintenance, Carpentry, Masonry, Welding, Auto Body Repair, and Auto Mechanics/Engine Repair. A multitude of other voluntary programs that afford the inmates opportunities for self-improvement are available as well to include Alcoholic Anonymous/Narcotics Anonymous, Veterans Incarcerated, Freedom and Choice, Victims Impact, Alternatives to Violence, Responsible Fatherhood, Responsible Fatherhood, 12 Steps, Conflict Resolution, Criminals and Gang Anonymous, Self-Awareness and Recovery, Celebrate Recovery, New Professionals, Leadership Development, Art and Healing, and Anger Management, Career Development, Arts Corrections, English as a Second Language, Al Anon, Veterans Support Group, Meditation.

Local Inmate Family Councils (IFC’s) are a gathering of family and friends of the incarcerated who meet regularly with Wardens to support visiting since keeping strong family connections with loved ones is a powerful rehabilitative tool. These IFC’s promote visiting by clarifying rules and regulations as well as discussing health, education, vocational training, packages, books, and related issues. For more information on connecting with a local IFC, please visit the Statewide IFC website.
