Texas Local Government Code - LOC GOV'T § 552.071. Corrections; Reassessments

(a) If an assessment is determined to be invalid or unenforceable, the governing body of the municipality may correct any deficiency in the proceedings relating to the assessment or any mistake or irregularity in connection with the assessment. The governing body may make and levy reassessments after a notice and hearing that comply as nearly as possible with the requirements for the original notice and hearing, and subject to the provisions relating to special benefits. A recital in a certificate issued as evidence of a reassessment has the same force as a recital in a certificate related to an original assessment.

(b) A person who owns or claims an interest in property against which a reassessment is levied has the same right of appeal provided under this subchapter for an original assessment. If the person does not appeal within 15 days after the date of the hearing relating to the reassessment, the provisions of Section 552.069 relating to waiver, bar, estoppel, and defense apply.
