While the Board may require public dedication of land to the Township, the Board and developer may mutually agree to dedicate the required land to a homeowners' association. In such a case, the Township Solicitor, prior to final approval, shall approve easements, covenants, homeowners' association documents or condominium declarations. The aforesaid instruments shall ensure the availability of the land to the residents of the subject plan, long-term maintenance with provisions guaranteeing such in favor of the Township wherein properties within the Township may equitably lien properties within the plan for work completed where the related association defaults on such maintenance, preservation of wooded areas and other natural resources, and the perpetual usage of the land for the intended open space or recreational purposes.
