Any person ordered to abate a nuisance or condition may have a hearing with the officer ordering the abatement as to whether the prohibited condition exists. A request for hearing must be made in writing and delivered to the officer ordering the abatement within the time stated in the notice, or it will be conclusively presumed that a nuisance or prohibited condition exists, and it must be abated as ordered. At the conclusion of the hearing, the hearing officer shall render a written decision as to whether a nuisance or prohibited condition exists. If he or she finds that a nuisance or prohibited condition exists, he or she must order it abated within an additional time which must be reasonable under the circumstances. An appeal from this decision may be had by immediately filing a written notice with the hearing officer. This appeal will be heard before the City Council at a time and place fixed by the Council. The findings of the Council shall be conclusive and, if a nuisance or prohibited condition is found to exist, it shall be ordered abated within a time reasonable under the circumstances.
