Maintenance of restricted open space. In the event that the party designated or organization established to own and maintain restricted open space, or any successor organization, shall at any time after establishment of the development fail to maintain the restricted open space in reasonable order and condition in accordance with the approved open space management plan, the Township may serve written notice upon such organization or upon the residents of the development setting forth the manner in which the organization has failed to maintain the restricted open space in reasonable condition, and said notice shall include a demand that such deficiencies of maintenance be cured within 30 days thereof, and shall state the date and place of a hearing thereon which shall be held within 14 days of the notice. At such hearing the Township may modify the terms of an extension of time within which they shall be cured. If the deficiencies set forth in the original notice or in the modifications thereof shall not be cured within said 30 days or any extension thereof, the Township, in order to preserve the taxable values of the properties within the development and to prevent the restricted open space from becoming a public nuisance, may enter upon said restricted open space and maintain the same for a period of one year. Said entry and maintenance shall not constitute a taking of said open space, nor vest in the public any rights to use the restricted open space except when the same is voluntarily dedicated to the public by the residents and owners. Before the expiration of said year, the Township shall, upon its initiative or upon the request of the organization theretofore responsible for the maintenance of the restricted open space, call a public hearing upon notice to such organization or to the residents of the development, to be held by the Township, at which hearing such organization or the residents of the development shall show cause why such maintenance by the Township shall not, at the option of the Township, continue for a succeeding year. If the Township shall determine that such organization is ready and able to maintain said restricted open space in a reasonable condition, the Township shall cease to maintain restricted open space at the end of said year. If the Township shall determine that such organization is not ready and able to maintain said restricted open space in a reasonable condition, the Township may, in its discretion, continue to maintain said restricted open space during the next succeeding year and, subject to a similar hearing and determination, in each year thereafter. The decision of the Township shall be subject to appeal to court in the same manner, and within the same time limitation, as is provided for zoning appeals by this chapter. The cost of such maintenance by the Township shall be assessed ratably against the properties within the development that have a right of enjoyment of the restricted open space and shall become a tax lien on said properties. The Township, at the time of entering upon said restricted open space for the purpose of maintenance, shall file a notice of such lien in the office of the Prothonotary of the county, upon the properties affected by such lien within the development.
