Grounds are grouped into the following Categories:

Installation Cantonment Area(s): Are defined as the geographic area(s) comprising the most urban areas of the installation. The areas are characterized by concentrations of pedestrians and permanent assets (facilities) for non-field training purposes. The cantonment area includes, but is not limited to, family and unaccompanied housing areas, schools, medical facilities, office facilities, an airfield, industrial facilities, limited recreational places and community activities. Cantonment Area(s) may include the main access roads with the road shoulders (10 feet from the edge of the roads) from the primary controlled security

Improved Grounds: This category includes acreage on which intensive landscape maintenance activities must be planned and performed annually as fixed requirements. Maintenance activities include mowing, irrigation, fertilization, cultivation, aeration, seeding, sodding, spraying, pruning and trimming; weed, dust, and erosion control; drainage; and planting for landscape effect, wind, and sound abatement, and other intensive practices. Examples are areas within the built- up section of an installation which contain lawns and landscape plants; parade grounds; drill fields; non-synthetic turf athletic field facilities; cemeteries; and similar areas.

Semi-improved Grounds: This category includes areas on which periodic recurring maintenance is performed but to a lesser degree than on improved grounds. Maintenance activities include mowing primarily for safety and security, weed and brush control, erosion control, dust control, and drainage maintenance. Examples are small arms ranges, antenna facilities, picnic areas, mowed road shoulders, ammunition storage areas, airfield shoulders and clear zones, drop zones, firebreaks, and similar areas.

Unimproved Grounds: This category includes all other acreage not classified as improved or semi-improved. Maintenance activities are generally unpredictable and normally evolve from the military mission; also, for soil, water, and wildlife conservation; floods; fires; insect infestations; and disease epidemics. Examples are bombing and gunnery areas; impact areas, training, and maneuver areas; forest areas; agricultural and grazing lands, lakes, ponds and swamps; beach and similar areas requiring limited or no maintenance.
