When any vessel or watercraft or obstruction is in danger of sinking, has been sunk or grounded, or has been delayed in such manner as to stop or seriously interfere with or endanger navigation, the harbor warden may order the same immediately removed. If the owner or other person in charge thereof, after being so ordered, does not proceed immediately with such removal, the harbor warden may take immediate possession thereof and remove the same. In so doing, the harbor warden shall use such methods as in the harbor warden’s judgment will prevent unnecessary damage to such vessel or watercraft or obstruction, and the expense incurred by the harbor warden in such removal shall be paid by the owner of the vessel, watercraft or obstruction. In case of failure to pay, the city may maintain an action for the recovery of such costs. (Ord. 1334 § 1, 2016; Ord. 766 § 2, 1997).
