8-7-1-9: DENSITY FORMULA:

   A.   Table 8-7-1-9A, "Estimated Ultimate Population Per Dwelling Unit", of this section is generally indicative of current and short range projected trends in family size for new construction and shall be used in calculating the amount of required dedication of acres of land or the cash contributions in lieu thereof, unless a written objection thereto is filed by the subdivider or developer.

   B.   In the event a subdivider or developer files a written objection to the table of estimated ultimate population per dwelling unit, as referenced in subsection A of this section, said subdivider or developer shall submit his own demographic study showing the estimated additional population to be generated from the subdivision or planned unit development, and in that event, final determination of the density formula to be used in such calculations shall be made by the county board, based upon such demographic information submitted by the subdivider or developer and from other sources which may be submitted to the county board by the school district or others. It is recognized that population density, age distribution and local conditions change over the years, and the specific formula components for the dedication of land, or the payment of fees in lieu thereof, as stated herein, are subject to periodic review and amendment upon verification of current data by the county board or its designee.

Note: There are only 3 significant categories provided in this table. Because of the similarity of yields of all types of attached single-family dwelling units, only 1 category is provided. The same is true with apartments; thus, only 1 category. Because of the relatively short history of some newer types of detached and attached single-family units, individual evaluations may be necessary.
