A.R.S. § 48-2077: Procedure if assessment declared void

A. If the assessment on a lot levied for an improvement under this article, or part of an improvement, or the entire assessment, is adjudged void for any reason, the board shall cause to be levied and assessed on the lot on which the assessment has been held void, or on all the lots included within the limits assessed for the work, a new assessment sufficient to provide for the payment of principal and interest on all bonds then unpaid. The reassessment shall be made as nearly as practicable in the same manner and with the same effect as the original assessment.

B. In case of partial deficit the board may pay the deficit from the general fund.
