Conn. Gen. Stat. § 7-145
In any case of assessment of damages or benefits for the layout or construction of public works, the Superior Court or any other appellate or revising tribunal to which such case may be removed may, by reassessment or otherwise, correct any errors which may be shown to exist in the report or schedule of such assessments, provided reasonable notice shall be given to any person, not before such court or tribunal, who may be injuriously affected by the correction of such errors to appear and show cause why such correction should not be made; but said court or such tribunal may, without special notice, correct manifest clerical errors and misdescriptions, when it is evident that no person interested has been misled thereby.
