(A) Because land is used more efficiently in a PUD, improved environmental quality can often be produced with a greater number of dwelling units per gross acre than usually permitted in a traditionally zoned district. The Plan Commission shall determine in each case the appropriate land use and dwelling unit density for individual projects or sections thereof.
(B) However, the following guidelines shall be adhered to:
(1) Residential densities:
(a) Overall. The maximum residential density for the overall project shall be five units, per acre: computed by comparing the total number of dwelling units to the gross land area of the project; and
(b) Sections. The maximum residential density for any particular section shall be 15 units per acre; computed by comparing the number of dwelling units within a particular section to the gross land area of that particular section.
(2) Land use ratios:
(a) Professional. Professional research, office or general business commercial or business uses may occupy up to a maximum of 20% of the gross land area;
(b) Manufacturing. Industrial uses may occupy up to a maximum of 10% of the gross land area; and
(c) Residential. The remainder of the area shall be devoted to residential uses; providing that, open space accompanies this land utilization at the rate of 12 acres for every 300 dwelling units.
