59-C-7.342. Population density. The appropriate density for each planned neighborhood application must be determined at the time of approval of the development plan and the granting of the planned neighborhood zone. The planning board's recommendation must take into account the availability of necessary public services and, where applicable, the provisions of the duly adopted and approved master plan for the subject area. The population density of a planned neighborhood must be planned so as to fall within a density range of from one to 15 persons per acre of land contained in the application, and must be calculated in accordance with the formula set forth in column B of the table in subsection 59-C-7.343 below; except that such planned population may be increased by an amount not to exceed 112 percent of the population to be housed in moderate priced dwelling units provided in accordance with chapter 25A of this Code, as amended, provided, that the total increase in population does not exceed 22 percent of the population which would otherwise be permitted.
