Construct a new 30 bed detention housing facility with support spaces to an existing 45 bed juvenile hall facility


Located on approximately 2 acres of county owned land, the project will construct three new buildings and an exterior covered walkway providing approximately 22,800 square feet of additional new housing, recreation yard, classrooms, mental health treatment rooms and offices, training/conference rooms, indoor multi-purpose/recreation, and administrative/teachers office space. 

The new maximum security housing facility will be a single story building with approximately 7,920  square feet of living space, with 20 single occupancy sleeping rooms. This new housing wing will also include a large day room to be used for eating meals and activities, and (2) Counseling Interview Rooms.  Adjacent to this housing facility will be a new outdoor recreation yard approximately 6,800 square feet.  The project will also include a bid alternate for an additional 10 single occupancy sleeping rooms within the proposed footprint of the housing facility.  The funding for this bid alternate would be provided by the county. 

The academics/administration building will be a two-story building of approximately 9,824  square feet.  This building will contain administration and staff support areas; classrooms, group treatment areas, counseling rooms; and mental health offices.

A multi-purpose/recreation facility will be a single story building with approximately 5,000 square feet of space.  This building will be accessible from the other buildings via an exterior covered walkway and will serve as an indoor large muscle exercise multipurpose gymnasium.  The gymnasium will allow daily physical education when it is raining or there is other inclement weather.

This project will include, but is not limited to, electrical; plumbing; mechanical; heating, ventilation, and air conditioning; security; digital cameras; and fire protection systems.  The buildings will be constructed of steel and concrete for long-term durability.  In addition, there will be a retention basin that provides storm water control measures, perimeter retaining walls, security systems, fire access road, and secure fencing surrounding the facility to provide grounds security.
