At such hearing physical facts which may be ascertained by view may be considered, whether proved or not.

A copy of such report, findings, and recommendations shall be mailed to the protestant 10 days before being presented to the Mayor, and the protestant may, before such report, findings, and recommendations are presented to the Mayor, file with such agent or agents exceptions to such report and findings, which exceptions shall be presented to the Mayor with such report, findings, and recommendations. The reassessment shall be made within 1 year from the date the judgment or decree quashing, setting aside, or declaring void the assessment becomes final and not subject to review. Notice of such reassessment shall be given the property owner in the same manner as if such reassessment was an original assessment, and such reassessment shall bear interest and be collected in the same manner as if such reassessment was an original assessment.
