Comprehensive plan means a generalized, coordinated land use map and policy statement of the governing body of a local government that interrelates all functional and natural systems and activities relating to the use of lands, including but not limited to sewer and water systems, trans- portation systems, educational facilities, recreational facilities, and natural resources and air and water quality management programs. “Comprehensive” means all-inclusive, both in terms of the geographic area covered and functional and natural activities and systems occurring in the area covered by the plan. “General nature” means a summary of policies and proposals in broad catego- ries and does not necessarily indicate specific locations of any area, activity or use. A plan is “co- ordinated” when the needs of all levels of governments, semipublic and private agencies and the citizens of Oregon have been considered and accommodated as much as possible. “Land” includes water, both surface and subsurface, and the air.
