82. The expression “urban agglomeration property roll” means, subject to the adjustment provided for in the second paragraph, the aggregate of all the property assessment rolls of the related municipalities that are applicable simultaneously.
For the purposes of the urban agglomeration property roll, each value entered on the property assessment roll of a reconstituted municipality is adjusted by dividing it by the median proportion of that roll and by multiplying the quotient so obtained by the median proportion of the property assessment roll of the central municipality.
For the purposes of the second paragraph, the median proportion of a roll is that established under section 264 of the Act for the first fiscal year for which the roll applies.
If all the related municipalities have a roll of rental values, the first three paragraphs apply, with the necessary modifications, and the aggregate of such rolls is called the “urban agglomeration rental roll”.
