This suitable <br />area and the proposed project are then subjected to either the residential or commercial <br />planned unit development density evaluation steps to arrive at an allowable number of <br />dwelling units or sites. <br />(E) Residential and commercial PUD density evaluation. The procedures for determining the base <br />density of a PUD and density increase multipliers are as follows. Allowable densities may be <br />transferred from any tier to any other tier further from the waterbody, but must not be transferred <br />to any other tier closer. <br />(1) Residential PUD base density evaluation. The suitable area within each tier is divided by the <br />single residential lot size standard for lakes or, for rivers, the single residential lot width <br />standard times the tier depth, unless the local unit of government has specified an alternative <br />minimum lot size for rivers which shall then be used to yield a base density of dwelling units <br />or sites for each tier. Proposed locations and numbers of dwelling units or sites for the <br />residential planned unit developments are then compared with the tier, density, suitability <br />analysis, and the design criteria contained herein. <br />(2) Commercial PUD base density evaluation. <br />a. Determine the average inside living area size of dwelling units or sites within each tier, <br />including both existing and proposed units and sites. Computation of inside living area <br />sizes need not include decks, patios, stoops, steps, garages, or porches and basements, <br />unless they are habitable space. <br />b. Select the appropriate floor area ratio from the following table: <br />Commercial Planned Unit Development <br />Floor Area Ratios*: Public waters classes <br />*Average unit <br />floor area <br />(sq. ft.) <br />Sewered general <br />development lakes; first <br />tier on unsewered <br />general development <br />lakes; tributary river <br />segments <br />Second and additional <br />tiers on unsewered <br />general development <br />lakes; recreational <br />development lakes <br />Natural <br />environment <br />lakes <br />200 <br />.040 <br />.020 <br />.010 <br />300 <br />.048 <br />.024 <br />.012 <br />400 <br />.056 <br />.028 <br />.014 <br />500 <br />.065 <br />.032 <br />.016 <br />600 <br />.072 <br />.038 <br />.019 <br />700 <br />.082 <br />.042 <br />.021 <br />800 <br />.091 <br />.046 <br />.023 <br />900 <br />.099 <br />.050 <br />.025 <br />11000 <br />.108 <br />.054 <br />.027 <br />11100 <br />.116 <br />.058 <br />.029 <br />11200 <br />.125 <br />.064 <br />.032 <br />11300 <br />.133 <br />.068 <br />.034 <br />11400 <br />.142 <br />.072 <br />.036 <br />11500 <br />.150 <br />.075 <br />.038 <br />Page 145 of 160 <br />
