This document provides a set of generalized guidelines for the design of units in large family campgrounds. Managers of recreational lands have two responsibilities and goals: to protect the natural resources, and to provide an enjoyable experience for users. With these goals in mind, unique variables to each unit such as shade, site aesthetics, and understory vegetation must be considered by careful and frequent onsite inspections. The following unit design factors are discussed: (1) site selection; (2) unit size; (3) unit construction; (4) unit furniture placement; (5) type of unit; (6) ramps and risers; (7) shade; (8) screening; (9) water movement; and (10) signs. Three basic unit designs are considered: the back-in, the pull-through, and the pull-off. Line illustrations depict unit base construction, surfacing, and placement of furniture (grill, electrical hookups, and tables). An appendix on tree and shrub response to recreation use ranks 27 hardwoods and conifers. (FG)
