This chapter may be enforced pursuant to the provisions of Chapter 15.28 of this code. If any violation of this chapter constitutes a seasonal and recurrent nuisance, the enforcement official shall so declare. Thereafter, such seasonal and recurrent nuisance shall be abated every year without the necessity of any further hearing. In the case of a previously declared seasonal and recurring nuisance, it is sufficient to mail a postcard notice to the owners of the property as they and their addresses appear on the current assessment roll. The notice shall set forth the street address and legal description or the county assessor’ s designation of the property. The notice shall state that a violation of Section 6.44.030 of a seasonal and recurring nature is existing on or in front of the property, that the same constitutes a public nuisance which must be abated by its removal, and that otherwise it will be removed and the nuisance will be abated by the enforcement official. The notice shall also state that the cost of such removal shall be assessed upon the lots and lands from which or in front of which such nuisance is removed, and will constitute a lien upon such lots and lands until paid pursuant to the provisions of Article III of Chapter 15.28 of this code.
