When the notice required by Section 3.44.090 of this chapter is sent, it shall be accompanied by a cover letter clearly explaining the notice, the intended use of the funds to be generated by the fee or charge, and the ballot procedures. In the event that the cover letter required by this section is not sent; or is sent but is incorrect or ambiguous in any manner; or is defective in any manner, no such failure, error, ambiguity or defect shall have any effect whatsoever on the jurisdiction of the city council to take any action, or on the validity of the proceedings including, but not limited to, establishment or levy of the fee or charge, or the validity of any of the documents required by this chapter. In case the cover letter is ambiguous or conflicts with the notice or any other document required by this chapter, the official document shall prevail and be the governing document. (Prior code § 62.08.806)
