A. The regularity or validity of an assessment may not be contested by a person who did not file with the city clerk a written objection to the assessment roll before its confirmation.
B. The decision of the council upon an objection may be appealed to the superior court within 30 days of the date of confirmation of the assessment roll. If no objection is filed or an appeal taken within that time, the assessment procedure shall be considered regular and valid in all respects. (Ord. 94-7 (part), 1994)
