18.03.140 - Emergency work.¶
This chapter shall not prevent any person from performing emergency maintenance or work within, on, over, under or through any watercourse without a permit as required in the previous section if unforeseen and urgent circumstances require such work to preserve life or property. The person performing the emergency work shall notify the enforcement officer the next working day and apply for a written permit within five calendar days of beginning the work. If an emergency exists, a city employee or agent may enter onto private property and perform drainage work necessary to restore the free flow of the watercourse. Before abatement, the city employee or agent shall make a diligent good faith effort, reasonable under the circumstances, to contact the property owner on whose property the drainage emergency exists. When abating a condition under this section, the enforcement officer shall document the nature of the emergency in writing. The property owner shall be responsible for payment of all such costs. After abatement, the city shall collect the costs from the property owner. If such costs are not paid within sixty (60) days, the enforcement officer shall proceed to fix a special assessment for the costs under Title 19 of this code. (Ord. 04-08 § 2 Exh. A (part))
