Nev. Rev. Stat. § 278A.130
The ordinance must provide that the city or county may accept the dedication of land or any interest therein for public use and maintenance, but the ordinance must not require, as a condition of the approval of a planned unit development, that land proposed to be set aside for common open space be dedicated or made available to public use. If any land is set aside for common open space, the planned unit development must be organized as a common-interest community in one of the forms permitted by chapter 116 of NRS. The ordinance may require that the association for the common-interest community may not be dissolved or dispose of any common open space by sale or otherwise, without first offering to dedicate the common open space to the city or county. That offer to dedicate the common open space must be accepted or rejected within 120 days.
