In addition to maintaining streets and providing water, sewer, and electric-utility services, the Department of Public Works staff also supplies and maintains all City-owned motorized vehicles and equipment through a motor-pool operation, and oversees major construction projects and other capital improvements.  Department of Parks and Recreation personnel assist Department of Public Works staff members with maintenance of various City-owned and -controlled downtown-area facilities and assist the Public Works staff and contractors with a City-wide forestry program.  (Department of Parks and Recreation staff members, in some cases assisted by contractors, are responsible for maintaining City-owned buildings and grounds.)
