Common Open Space Maintenance. If the organization established to own and maintain common open space, or any successor organization fails to maintain such common open space in reasonable order and condition in accordance with the development plan, the Borough may serve written notice upon such organization or upon the residents of the planned residential development setting forth the maintenance deficiencies, requiring correction of deficiencies within 30 days, and stating the date and place of a hearing thereon which shall be held within 14 days of the notice. At such hearing the Borough 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 so set forth shall not be corrected within the specified time limit, the Borough, in order to preserve the taxable values of the properties within the planned residential development and to prevent the common open space from becoming a public nuisance, may enter upon and maintain the common open space for one year. This maintenance shall not constitute a taking nor vest in the public any rights to use the common open space. Before the expiration of the year, the Council shall set a public hearing where such organization or residents of the planned residential development may show cause why maintenance by the Borough should not continue for another year. If Council determines that such organization is ready and able to maintain said common open space in reasonable condition, the Borough shall cease to maintain said common open space at the end of said year. If the Council shall determine that such organization is not ready and able to maintain said common open space in a reasonable condition, the Borough 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 cost of such maintenance by the Borough shall be assessed ratably against the properties within the planned residential development that have a right of enjoyment of the common open space, and shall become a lien on said properties. The Borough at the time of entering upon said common open space for the purpose of maintenance shall file with the County a notice of lien upon properties affected.
