Any person ordered to abate a nuisance may have a hearing with the Mayor or Code Enforcement Officer or his designated representative ordering the abatement. A request for a hearing must be made in writing and delivered to the Village Clerk within the time stated in the notice; otherwise, it will be presumed that a nuisance exists, and that such nuisance must be abated as ordered. The hearing shall not be a formal trial-type proceeding, but appropriate procedural safeguards shall be observed to ensure fairness. At the conclusion of the hearing, the Mayor or Code Enforcement Officer or his designated representative shall render his decision and the reasons therefor in writing. If he finds that a nuisance exists, he shall order it abated within an additional time which must be reasonable under the circumstances.
