In the event that any officially designated historic site or landmark or contributing building, structure, site or object within the Historic District deteriorates to the point that, in the best reasonable estimate by a qualified, licensed professional, designated and appointed by the Township Committee of the costs of correcting the outstanding code violations and/or conditions equals more than 25% of the cost of replacing the entire structure on which the violations or conditions occur, the Zoning Officer shall serve personally or by certified mail, return receipt requested, a notice to the owner of an historic site or landmark or contributing building, structure, site or object within the Historic District listing the violation or condition, the estimate for the abatement with materials of the same or similar style, material and historical aesthetic, and the replacement cost of the structure. The notice shall also state that if the owner does not take all necessary remedial action within 60 days, or such extensions as the Zoning Officer grants for good cause, the Township may enter upon the property and abate such violations and conditions itself and cause the cost to become a lien on the property in accordance with § 230-202.3B(4)(e).
