(a) The judgment and decree of the commissioners of appraisement reassessing benefits in the district are the basis of the assessment of taxes in the district.
(b) The assessment can again be modified or changed but there can be no reassessment of benefits that will in any way render any outstanding bonds or other indebtedness of the district insecure. The sum of benefits as reassessed may never be less than the sum of all outstanding bonds and other indebtedness of the district.

(c) The commissioners court of each county in which the district is located shall levy and have assessed and collected taxes based on the reassessment, at a rate sufficient to provide funds to pay the interest on all outstanding bonds and other indebtedness of the district, to pay the bonds or other indebtedness at maturity, and to provide the necessary sinking funds to pay all bonds or other indebtedness that may be issued.
(d) If the engineer’s report is modified, or if extensive repairs or additions are made, the provisions of this section apply to districts that levy taxes on the ad valorem basis, but the commissioners of appraisement shall assess only the damages which will accrue to the property inside or outside the district as a result of the changes in the report.
