1 *For average unit floor areas less than shown, use the floor area ratios listed for 200 square feet. For areas greater <br />2 than shown, use the ratios listed for 1,500 square feet. For recreational camping areas, use the ratios listed at 400 <br />3 square feet. Manufactured home sites in recreational camping areas shall use a ratio equal to the size of the <br />4 manufactured home, or if unknown, the ratio listed for 1,000 square feet. <br />5 <br />6 c. Multiply the suitable area within each tier by the floor area ratio to yield total floor area <br />7 for each tier allowed to be used for dwelling units or sites. <br />8 d. Divide the total floor area by tier computed in subsection (e)(2)c of this section by the <br />9 average inside living area size determined in subsection (e)(2)a of this section. This <br />10 yields a base number of dwelling units and sites for each tier. <br />11 e. Proposed locations and numbers of dwelling units or sites for the commercial planned <br />12 unit development are then compared with the tier, density and suitability analyses <br />13 herein and the design criteria. <br />14 (3) Density increase multipliers. <br />15 a. Increases to the dwelling unit or dwelling site base densities previously determined are <br />16 allowable if the dimensional standards are met or exceeded and the design criteria are <br />17 satisfied. The allowable density increases in subsection (e)(3)b of this section will only <br />18 be allowed if structure setbacks from the ordinary high water level are increased to at <br />19 least 50 percent greater than the minimum setback, or the impact on the waterbody is <br />20 reduced an equivalent amount through vegetative management, topography, or <br />21 additional means acceptable to the local unit of government and the setback is at least <br />22 25 percent greater than the minimum setback. <br />23 b. Allowable dwelling unit or dwelling site density increases for residential or commercial <br />24 planned unit developments: <br />25 <br />Density Evaluation Tiers Maximum Density Increase <br />Within Each Tier <br />(percent) <br />First 50 <br />Second 100 <br />Third 200 <br />Fourth 200 <br />Fifth 200 <br />26 <br />27 (4) Maintenance and design criteria. <br />28 a. Maintenance and administration requirements. <br />29 1. Before final approval of a planned unit development, adequate provisions must <br />30 be developed for preservation and maintenance in perpetuity of open spaces and <br />31 for the continued existence and functioning of the development. <br />32 2. Open space preservation. Deed restrictions, covenants, permanent easements, <br />33 public dedication and acceptance, or other equally effective and permanent <br />34 means must be provided to ensure long-term preservation and maintenance of <br />35 open space. The instruments must include all of the following protections: <br />36 (i) Commercial uses prohibited (for residential PUDs); <br />37 (ii) Vegetation and topographic alterations other than routine maintenance <br />38 prohibited; <br />39 (iii) Construction of additional buildings or storage of vehicles and other <br />40 materials prohibited; and <br />41 (iv) Uncontrolled beaching of watercraft prohibited. <br />Page 146 of 160 <br />
