Colesville Maintenance Facility. Montgomery County, Maryland.

Modernization of this county facility was paramount to road maintenance and safety in Montgomery County.

The renovation and addition to the 7,000 SF depot resulted in a new 12,000 SF maintenance facility. The facility includes offices, crew/bunk/training room, and service bays capable of handling large trucks. The extension of covered truck parking for 50 spaces and covered material bins were also included in the design. A 10,000 ton salt storage facility, which includes a large salt barn with lean-to for crew equipment, was incorporated in the maintenance facility campus. This facility is designed to LEED Gold.
