Corrections With Compassion

San Mateo County Maple Street Correctional Center
Redwood City, California, USA

“Building sustainably was the right thing to do. Not only have we ensured we have a safe and secure facility, this building's efficiency conserves natural resources and is a cost savings for the county.”

Dave Titus, Lieutenant, San Mateo County Sheriff's Office

The Maple Street Correctional Center redefines the roles of county detention and state corrections facilities.

Designed to reduce recidivism, this is the first correctional center to open in the wake of California’s initiative to move non-violent, non-sexual offenders from overcrowded state prisons to county correctional centers.

In developing the design, HOK assessed the short- and long-term needs of the male and female inmates while considering how staff would manage these disparate population groups within a hybrid facility.

Our team initially developed several concepts for the 260,000-sq.-ft. correctional center, studying how each design responded to the climate and location. The final plan, approved by stakeholders and construction partners, incorporated two separate but connected buildings that allowed the administrative area to be built in a more cost-effective, aesthetically pleasing way.

The jail structure features secure windows and walls located inside the building shell, a design detail that bolsters security and allows for more daylight to enter the facility. Instead of placing cells along the exterior, as in most jails, the team put dayrooms along the windows that open to individual living units. This allows for natural lighting throughout the 832-bed jail.   

Other features intended to improve the rehabilitation and lives of inmates include core stations that offer computer and classroom space as well as natural ventilation, artwork and natural color palettes.

The project includes an 88-bed transitional housing facility for day reporting, weekend programs and other alternatively sentenced inmates.

HOK’s integrated architectural, engineering and landscape architecture design team collaborated to design a high-performance, LEED Gold certified facility.
