Desert Preservation Task Force definitions:
Meaningful Open Space: Open space which due to its size, function, visibility, accessibility and/or strategic location is a community amenity or resource. Open space which can be accessed or can be viewed by the public. Open space which serves to protect a significant ecological area. Meaningful Open Space is divided into three categories: accessible desert open space consisting of public use areas and public access areas; visual desert open space consisting of mountain and desert conservation areas, wash corridors and street setbacks; and desert character open space consisting of restored areas such as detention basins and drainage channels and improved areas such as parks and golf courses that have a desert character.
Natural Area Open Space: Areas of undisturbed natural desert with no man-made improvements and approved revegetated areas.
Developed Open Space: landscape areas, turf areas, parks, golf courses and other recreational facilities excluding any associated buildings.
