The validity of any special assessment and lien imposed under Section 13.12.100 shall not be contested in any action or proceeding unless the action or proceeding is commenced within thirty (30) days after the date the city council adopts the resolution confirming the report of delinquent utility services charges. An owner's failure to file a timely objection or protest, make a timely request for a hearing, appear at the hearing, or present their objection or protest to the city council, in accordance with Section 13.12.100, constitutes a failure to exhaust administrative remedies with regard to the special assessment. (Ord. 2015-0011 § 16; Ord. 2011-051 § 2)
