The Legislature is concerned that school playgrounds, playing fields, and recreational real property will be lost for those uses by the surrounding communities even if those communities in their planning process have assumed that the properties would be permanently available for recreational purposes. It is the intent of the Legislature in enacting this article to allow school districts to recover their investment in surplus property while making it possible for other agencies of government to acquire the property and keep it available for playground, playing field or other outdoor recreational and open-space purposes.
