HMN Architects, Inc. worked with Clay County on a 28-Bed Detention
Center and Sheriff's Office. This new building is on the site of the
existing Sheriff's Office. Merging the jail with the Sheriff's Office
meant that there were a variety of stakeholders involved in the design
process. Recognizing the varied needs of staff and incorporating them
into the design proved challenging, but HMN Architects listened to the
client and was able to include their requests within the budget. By
meeting with the Sheriff, Chief Deputy, Investigator, Jail Administrator
and Board of Supervisors, HMN was able to design a facility that worked
for all parties.
The new facility has 20 general population beds with another six
dedicated to work release and two for medical / administrative
segregation. The new booking area has six holding cells and gives the
County a larger capacity for booking, along with the ability to classify
inmates despite their small bed count. Using an indirect, single post
supervision style, the jail has five dayrooms. The space also includes a
warming kitchen, laundry and an indoor/outdoor exercise yard.
There are a few design features requested by the County that are unique
to a jail of this size. The large evidence storage has been designed to
accommodate the County's growing capabilities, and the evidence
processing area has pass-through lockers. It was important to the
Sheriff to provide a squad room with individual work spaces for road
patrol, which was incorporated into the design. To accommodate the
colder climate, the vehicular sally port allows for indoor parking. The
facility also has a large training and meeting space that will be used
by the community, as well as law enforcement. This area can also double
as an emergency operation center with a concrete lid and masonry walls.
In terms of the exterior design, the administration uses fiber
reinforced concrete skin over metal studs with a mixture of low slope
roofs and standing metal seam slopes. Two colors of precast panels were
used for the detention area. To design for the climate, the team
utilized sustainability concepts and geothermal technology to increase
The HMN team included a local architect with strong ties to the
community who had an understanding of the community's design aesthetic.
