      (1)   Unless specifically required by a plat, ordinance or recorded covenant that has been approved for recording by the Village Board, the owners of all properties in a subdivision wherein an OS designated retention or detention area has been platted and developed shall bear all liability, jointly and severally, for the maintenance, upkeep and condition of the parcel; and they shall neither permit nor suffer any use of any area in a manner inconsistent with or which interferes with its intended use as a stormwater buffer.
      (2)   The owners of all properties described in division (D)(1) shall, upon written request of the village, perform any and all necessary maintenance to any area, including the removal of brush, bushes or trees, the re-grading of eroded soils, the dredging and removal of silt and all other things reasonably necessary to the continued function of the area for its intended use as a stormwater buffer.
      (3)   If the owners of all properties described in division (D)(1) fail to honor the request of the village made pursuant to division (D)(2) within a reasonable time of the request, the village shall have the right, but not the obligation, to enter upon the OS designated property and perform the required maintenance, and the village may issue statements to the said owners, on a pro-rata basis, requiring them to pay their proportionate share of the expenses, calculated at 150% of the ascertainable actual cost of the maintenance in order to cover the expense of enforcement and administration, and if any of the owners should fail to pay the statement within 30 days of issuance, these charges shall become a lien upon their individual lots which the village may memorialize by the recording of a formal notice of lien with the Lake County Recorder of Deeds.
