The intent of this chapter is to provide a flexible framework within which populous and rapidly growing cities and counties in this state can develop a program of community greenspace preservation. The General Assembly recognizes that the unique characteristics of each region throughout the state preclude a mandated legislative outcome for the preservation of greenspace in every region. The process provided by this chapter is intended to promote adoption in developed and rapidly developing areas of policies, rules, and regulations which will have the effect of preserving at least 20 percent of the land area as connected and open greenspace which can be utilized for informal recreational activities and protection of natural resources. This chapter will also provide a resource of funding for preservation of such greenspace, which will augment currently available local, state, and federal funding.
