On the Boards – Justice

From concept design through construction administration, Nacht & Lewis is pleased to share details of exciting new projects we are working on. Take a look below at what we've got on the boards with highlights of our latest projects in-progress.

Butte County Jail SB 863 Expansion


A new stand-alone 132-bed jail facility consisting of four 24-bed maximum security pods and a 36-bed medical and mental health treatment housing unit. The addition includes a new intake and release facility, a medical clinic with medical dental exam rooms, a pharmacy, nursing station and clinician work areas. The County’s existing jail has a rated capacity of 614 beds. The new facility will replace 96 of the existing beds that are in the older linear jail housing.

Napa County Staff Secure Transitional Housing

Napa County Department of Corrections envisions a 72-Bed, 20,962 s.f. Staff Secure Facility (State of California Board of State and Community Corrections (BSCC) Type IV). This minimum custody correctional facility will provide an environment that fosters cognitive behavioral change and allow individuals to build a foundation for transition back into the community. The County received a conditional funding award of $13 million through SB1022 for the design and construction of the new facility. As the first project of a multi-phased, master planned relocation of Napa County’s Main Jail, the project includes bringing new utility infrastructure from offsite to support the new facility and the future build-out of the new jail. This project will meet LEED Gold sustainability goals at a minimum.

New Napa County Jail Facility

Nacht & Lewis is working with the County of Napa to design a new jail, which will be a replacement for the current jail facility located in downtown Napa. It will serve as the primary jail for the county, housing new arrestees, pre-trial and sentenced inmates. It will primarily house medium and maximum security inmates with an initial population of 256 inmates in eight 16-Cell, 32-Bed pods.

The support areas (administration offices, infirmary, clinic, staff services and lockers, intake, food services and laundry) will support an expanded inmate population of 526 and the facility master plan, the available site area and the circulation system will accommodate further expansion. Storage and program areas are designed to be expanded with an increase in population as well. The jail will also provide 31 non-rated infirmary beds in a mix of medical and mental health patient rooms. The special needs beds will be located adjacent to the medical clinic, which also serves the rest of the jail in an “outpatient” fashion. This project will meet LEED Gold sustainability goals at a minimum.

Amador County Jail SB 863 Expansion


Nacht & Lewis (N&L) is currently working on the 40-bed mail jail housing unit expansion at the Amador County Jail in Jackson, California. The new 14,051 square foot building will be a stand-alone building next to the mail jail and will provide two, 20-bed maximum security housing pods, programming and treatment space, a safety cell, respiratory isolation cell, recreation yard, central control, medical exam room, dental exam room, program/group rooms, an interview room, office space, covered exterior circulation and a storage basement. A covered and fenced pathway will connect the new building to the existing jail. Site improvements are included that expand the parking capacity for Jail and Sheriff’s Department staff.

The most significant challenge the N&L team faced was how to build the new housing unit at the same elevation when the available land for development sloped significantly away from the existing jail. Nacht & Lewis in collaboration with the structural engineer, CYS Structural Engineers, studied various structural alternatives that balanced the functional and budgetary requirements for the project.

Prior to beginning design, Nacht & Lewis conducted a comprehensive needs assessment of the County’s only jail facility. The assessment included a Facility Condition Assessment, preparation of a jail population profile and population projections, architectural programming, conceptual planning and development of a comprehensive time-phased construction plan.

In order to secure funding for the project, Amador County, Amador County Sheriff’s Department and N&L worked together to prepare the County’s SB 863 funding application. As a result, the County was awarded $17.1 million, the majority of the funding necessary for the expansion to be designed and constructed.

Nacht & Lewis is currently under contract for Basic Services as the County’s Architect of Record (AOR). Project completion is slated for early 2020.
