Development Standards—Density and Dimensions | Town Center
H. Calculations – Site area used for minimum density calculations
expressed in square feet and measured from the interior face of exterior walls. Structured or underground parking areas and areas housing mechanical equipment shall be excluded from commercial floor area calculations; and 4. When calculations result in a fraction, the fraction shall be rounded to the nearest whole number as follows:
Minimum density shall be determined by multiplying the minimum density (dwelling units/acre) as set forth in SDC 21.07.050C.1. by the gross developable acreage of the project site as forth in SDC 21.07.050H.
Lot area – Prohibited reduction
I.
a. Fractions of 0.50 or above shall be rounded up; and
Any portion of a lot that was used to calculate compliance with the standards and regulations of this Chapter shall not be subsequently subdivided or segregated from such lot.
b. Fractions below 0.50 shall be rounded down.
G. Calculations – Gross developable acreage
1. All site areas may be used in the calculation of allocated and maximum allowed residential density or project floor area except as outlined under the provisions of subsection 2. of this section. 2. Submerged lands, landslide hazard areas and buffers, Category I through IV wetlands and buffers, and Type S, F, Np, and Ns streams and buffers shall not be credited toward allocated and maximum density or floor area calculations. Property used for new roadways, trails, stormwater facilities, or other features used by residents or the general public shall be counted as part of the site area for density calculations. Property transferred to the City for the construction of public roadways or other public feature shall be counted as part of the site area if the City and property owner reach such an agreement as part of the transfer.
J. Measurement of setbacks
1. Street Setback. The street setback is measured from the street right-of-way or the edge of a surface improvement which extends beyond a right-of-way, whichever is closer to the proposed structure, to a line parallel to and measured perpendicularly from the street right-of-way or the edge of the surface improvement at the depth prescribed for each zone. 2. Side Yard Setback. The side setback is measured from the side lot line adjacent to another private property to a line parallel to and measured perpendicularly from the side lot lines at the depth prescribed for each zone. 3. Back Yard Setback. The back yard setback is measured from the rear lot line adjacent to another private property to a line parallel to and measured perpendicularly from the rear lot lines at the depth prescribed for each zone.
