At such hearing, the Borough Council may modify the terms of the original notice as to deficiencies and may give a reasonable extension of time not to exceed 65 days within which they shall be remedied. If the deficiencies set forth in the original notice or in the modification thereof shall not be remedied within said 35 days or any permitted extension thereof, the municipality, in order to preserve the open space and maintain the same, may enter and maintain such land for a period of one year. Said entry and maintenance shall not vest in the public any rights to use the open space except when the same is voluntarily dedicated to the public by the owners. Before the expiration date of said year, the Borough Council shall upon its initiative or upon the request of the organization theretofore responsible for the maintenance of the open space, call a public hearing upon 15 days' written notice to such organization and to the owners of the development, to be held by the Borough Council at which hearing such organization and the owners of the development shall show cause why such maintenance by the municipality shall not, at the election of the municipality, continue for a succeeding year. If the Borough Council shall determine that such organization is ready and able to maintain said open space in reasonable condition, the municipality shall cease to maintain said open space at the end of said year. If the Borough Council shall determine such organization is not ready and able to maintain said open space in a reasonable condition, the municipality may, in its discretion, continue to maintain said open space during the next succeeding year, subject to a similar hearing and determination, in each year thereafter. The decision of the Municipal Body or officer in any such case shall constitute a final administrative decision subject to judicial review.
