TRAVERSE CITY — Grand Traverse County’s aging jail is slowly shifting on its foundation, and while engineers say the situation is not yet an emergency, county officials are moving ahead with plans to eventually replace the decades-old facility.
At a recent Board of Commissioners meeting, the County’s facilities director and a structural engineer from a Michigan-based engineering firm delivered an update on ongoing monitoring of the jail, which was originally constructed in the 1960s with a major addition built in the 1980s. Both painted a picture of a building that still functions but is deteriorating in ways that demand attention — and a timeline for action.
The facilities director told commissioners he would rate the jail’s condition a five on a scale of zero to ten, with ten meaning immediate evacuation is necessary. He described the status as “yellow” — not an emergency, but clearly cause for concern.
To illustrate the situation, he compared the facility to a classic 1957 Chevrolet — attractive on the outside, but rusting underneath, with no way to predict when the frame might give out. The question, he told commissioners, is not whether the county will need to leave the jail, but when.
Engineers have documented multiple instances of the building settling and then partially rebounding, a cycle they say is driven by soil conditions beneath the structure. The movement is measured in millimeters, but across a building of that size, even small shifts create real problems.
Between October and January, monitoring equipment recorded roughly a millimeter of new movement in the tunnel that connects the jail to the adjacent government center — a small but recordable event that prompted further investigation.
Ground-penetrating radar studies conducted in the jail’s basement revealed underground voids, likely the remnants of old catch basins, pipes and an oil tank left from structures that previously occupied the site. Engineers said these buried remnants are gradually making themselves known as soils shift and settle over time.
The sheriff’s office raised more immediate operational concerns. Since a significant movement event last June, new cracks have appeared throughout the facility in areas that were previously undamaged. More troubling, some doors in the jail now open or close depending on which direction the building is leaning at any given time. An official told commissioners that if a sudden shift were to pin a door shut with an inmate on the other side, it would create a serious safety problem. The sheriff’s office confirmed it has a continuity of operations plan and could execute a full evacuation if necessary, but stressed that a controlled, planned departure is far preferable to a crisis-driven one.
The engineering firm recommended that the county seriously consider moving into a new or fully remodeled facility within three to five years. In the meantime, officials said they would continue monitoring the building and reassess conditions in about a year to determine whether interim repairs are needed to buy additional time.
On the planning side, commissioners approved a professional services contract with a real estate and facilities consulting firm to begin the process of determining what comes next. The firm, which has worked with Oakland, Macomb, and Wayne counties on similar large-scale government facility projects, told commissioners it plans to study space needs across county departments, develop multiple scenarios for a new facility, and present options with cost, timeline and location data by July.
The consultants emphasized that their approach is built around consensus. Rather than delivering a single recommendation, they said they intend to bring commissioners a menu of options and engage the board throughout the process to avoid the kind of disconnect that plagued an earlier planning report that commissioners found lacking.
To keep the project moving, commissioners voted to designate the county’s representatives on the Joint Building Commission — a body that includes both county and city officials — as the liaison with the consulting firm. The board also directed that it receive monthly updates on the project’s progress at regular business meetings.
County and city officials have already begun coordinating, with the city designating its assistant city manager as its point of contact. Officials acknowledged the county is roughly a year ahead of the city in its planning, but said both sides are committed to working together.
The message from the meeting was clear: the clock is ticking, and officials want to stay ahead of it.
