The Behavioral Health and Treatment Center at Maple Lane Campus is DSHS’ first behavioral health treatment center created to treat patients in the community and in smaller facilities that better meet their needs. Since 2016, Maple Lane Campus has provided treatment for a variety of residents in need of behavioral health treatment.
Campus and Units
The Maple Lane Campus first opened in 1914 as a training school for girls, the Washington State School for Girls. For nearly 100 years, it served various populations under the Department of Corrections until it was closed in 2011.
DSHS first opened Cascade Unit on the Maple Lane Campus in April 2016, serving up to 30 residents in need of competency restoration. In July 2024, the unit reopened to serve residents found not guilty by reason of insanity.
Oak Unit opened in April 2023 to serve up to 16 residents under civil commitment.
Columbia Unit opened in February 2024 and serves up to 30 residents found not guilty by reason of insanity.
Baker Unit opened in October 2025 and serves 32 residents under civil commitment.
Residents
Maple Lane Campus provides treatment for two types of residents:
NGRI - people in need of inpatient psychiatric care who have been found not guilty by reason of insanity and have made substantial progress in their treatment.
Civil – people who received an involuntary commitment order by the court through a civil commitment proceeding under RCW 71.05.
Maple Lane Campus residents remain in a secure setting. We provide services and activities that are respectful to people across all cultures and backgrounds. These services include:
- initial intake and evaluation,
- medical screening, psychiatric screening, risk screening,
- psychological/biological/social evaluation,
- treatment and peer support.
The goal is to stabilize the illness and improve the person’s mental status and behavior. We want them to recover and be able to return to their home or another, less-restrictive living arrangement with appropriate integration into aftercare services.
All residents receive thorough individualized discharge plans with the support needed to meet their needs in the community. These include wraparound supports like medication management, case management, and medical care. Discharged residents are given a warm handoff to their next location, including transportation to their next residence from DSHS.
Our goal is for the Maple Lane Campus to become a part of the community as a resource and a partner.
Security
Entrances and exits are controlled by staff. The outdoor spaces for the residents are enclosed by fencing. The facility also has agreements with local law enforcement to assist as needed. Staff are trained in de-escalation strategies and emergency management processes to minimize calls to law enforcement and the fire department.
Every unit except for Oak is located behind fencing and a secured gate. No one is able to enter Maple Lane Campus without authorization.
No services are provided for people who are not living at the facility. Maple Lane is a closed campus with no public restrooms, shelter services, or behavioral health services that can be accessed by the public. This is a controlled secure environment for people receiving inpatient treatment from DSHS. Visits are limited to friends and family and must be scheduled.
Any planned trips off campus by residents include staff members as escorts. Off-site trips might consist of trips to the local hospital, medical appointments, or housing appointments. Residents may also participate in trips that are treatment or recovery focused, such as sober supports in the community, or activities that are recreational and help with community reintegration, such as shopping, restaurants, getting familiar with public transportation, outdoors activities, and various community errands. The goal of these trips is to prepare residents to transition back into their community following their treatment.
