Organizational ownership of open space. In the event that the organization established to own and maintain common open space, or any successor organization, shall, at any time after establishment of the Multiple-Family Residential District, fail to maintain the common open space in reasonable order and condition and in accordance with the development plan, the borough may serve written notice upon such organization or upon the residents of the Multiple-Family Residential District, setting forth the manner in which the organization has failed to maintain the common open space in reasonable condition, and said notice shall include a demand that such deficiencies of maintenance be corrected 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 municipality may modify the terms of the original notice as to the deficiencies and may give an extension of time within which they shall be corrected. If the deficiencies set forth in the original notice or in the modifications thereof shall not be corrected within said 30 days or any extension thereof, the municipality, in order to preserve the taxable values of the properties within the Multiple-Family Residential District and to prevent the common open space from becoming a public nuisance, may enter upon said common open space and maintain the same for a period of one year. Said maintenance by the municipality shall not constitute a taking of said common open space nor vest in the public any rights to use the same. Before the expiration of said year, the municipality shall, upon its initiative or upon the request of the organization theretofor responsible for the maintenance of the common open space, call a public hearing, upon notice to such organization or to the residents of the Multiple-Family Residential District, to be held by the governing body or any designated agency, at which hearing such organization or the residents of the Multiple-Family Residential District shall show cause why such maintenance by the municipality shall not, at the option of the municipality, continue for a succeeding year. If the governing body or its designated agency shall determine that such organization is not ready and able to maintain said common open space in a reasonable condition, the municipality may, in its discretion, continue to maintain said common open space during the next succeeding year and, subject to a similar hearing and determination, in each year thereafter. The decision of the governing body or its designated agency shall be subject to appeal in court in the same manner and within the same time limitation as is provided for zoning appeals by statute. The cost of such maintenance by the municipality shall be assessed by rate against the properties within the Multiple-Family Residential District that have a right of enjoyment of the common open space and shall become a lien on said properties. The municipality, at the time of entering upon said common open space for the purpose of maintenance, shall file a notice of lien in the office of the prothonotary of the county upon the properties affected by the lien within the Multiple-Family Residential District.
