The effort to build a new central ambulance garage in Sturgeon Bay could move one step closer to reality on Tuesday during the meeting of the Door County Board. Supervisors will be asked to authorize phase three of the project and the expenditure of no more than $2.7 million to construct the facility, with the work to be paid for by way of monies on hand, general revenue or borrowing. Phase three encompasses the development of final drawings, firm cost estimates and the bidding process. The current ambulance garage, adjacent to Ministry Door County Medical Center, at 319 South 18th Avenue, is inadequate to meet the department’s needs related to vehicle and equipment storage and personnel. The county is working with the hospital on a new lease for a parcel off Michigan Street and across from the YMCA. If all goes well, the new central ambulance station will be built on that property.
