(A) The procedures for determining the “base” density of a PUD and density increase multipliers are as follows.
(B) Allowable densities may be transferred from any tier to any other tier further from the waterbody, but shall not be transferred to any other tier closer.
(1) Residential PUD “base” density evaluation. The suitable area within each tier is divided by the minimum single residential lot size standard for lakes to determine the maximum permitted density. Proposed locations and number of dwelling units or sites for residential planned developments are then compared with the tier, density and suitability analyses herein and the design criteria in § 153.156.
(2) Commercial PUD “base” density evaluation. Determine the average inside living area size of dwelling units or sites within each tier, including both existing and proposed units and sites. Computation of inside living area sizes shall not include decks, patios, stoops, steps, garages or porches and basements, unless they are habitable space.
(3) Floor area ratio.
(a) Select the appropriate floor area ratio from the following table:
Commercial PUD Floor Area Ratios and Public Waters Classes
| |
Average Unit Floor Area (square feet) | General Development Lakes |
Commercial PUD Floor Area Ratios and Public Waters Classes
| |
Average Unit Floor Area (square feet) | General Development Lakes |
400 | .056 |
500 | .065 |
600 | .072 |
700 | .082 |
800 | .091 |
900 | .099 |
1,000 | .108 |
1,100 | .116 |
1,200 | .125 |
1,300 | .133 |
1,400 | .142 |
1,500 and above | .150 |
(b) Multiply the suitable area within each tier by the floor area ratio to yield total floor area for each tier allowed to be used for dwelling units or sites.
(c) Divide the total floor area by tier, computed in division (B)(3)(b) above, by the average inside living area size determined herein. This yields a base number of dwelling units and sites for each tier.
(d) Proposed locations and number of dwelling units or sites for the commercial planned development are then compared with the tier, density and suitability analyses herein and the design criteria in § 153.156.
(4) Density increase multipliers.
(a) Increases to the dwelling unit or dwelling site base densities previously determined are allowable if the dimensional standards listed herein are met or exceeded and the design criteria in § 153.156 below are satisfied. The allowable density increases herein below will only be allowed if structure setbacks from the ordinary high water level are increased to at least 50% greater than the minimum setback, or the impact on the waterbody is reduced an equivalent amount through vegetative management, topography or additional means acceptable to the city and the setback is at least 25% greater than the minimum setback.
(b) Allowable dwelling unit or dwelling site density increases for residential or commercial planned unit developments:
Density Evaluation Tiers | Maximum Density Increase in Each Tier |
First | 50% |
Second | 100% |
Third | 200% |
Fourth | 200% |
Fifth | 200% |
