The director of public works shall serve notice on the owner of premises containing infected trees or firewood, said notice to be in conformance with 65 Illinois Compiled Statutes 5/11-20-12. The notice shall be served by registered mail or personally on the person to whom was sent the tax bill for general taxes on said property for the last preceding year and the notice shall be delivered or sent not less than thirty (30) days prior to the removal of the tree(s). In the event the tree or firewood is not removed within said thirty (30) day period, the village shall proceed to remove the tree(s) or firewood, charge the cost to the owner, and in the event of nonpayment, file a lien against the property in accordance with 65 Illinois Compiled Statutes 5/11-20-12. In the event a tree is particularly infectious because of its proximity to other elm or ash trees or because of the time of year the disease is discovered, then the notice shall be five (5) days instead of thirty (30) days. The department of public works shall determine when the conditions exist warranting the imposition of the shorter notice period based on the foregoing standards. (Ord. 06-O-975, 10-2-2006)
