Sec. 250424. - Minimum distance between buildings and building orientations.
(1) Standard building separations: Buildings shall be separated from one another as follows:
(a) Side to side separation shall be a minimum twenty (20) feet or the average of the height of adjacent buildings whichever is greater. An additional one (1) foot separation shall be required for each three (3) feet that the average length of adjacent buildings exceeds one hundred thirty (130) feet. If the height of the end of the building is lower than the height of the adjacent roof section on the same building by at least five (5) feet over a width of at least twenty (20) feet, the lower height may be used in calculating the average height of the building for this section.
(b) Side to front or side to back separation shall be twenty-five (25) feet or the average height of adjacent buildings, whichever is greater.
(c) Front to front, front to back, or back to back separation shall be 35 feet or the average of the height of adjacent buildings whichever is greater. However, the average separation between buildings shall not be less than forty (40) feet.
(2) Special building separations:
(a) Buildings arranged in a lineal form with a combined length in excess of four hundred (400) feet shall have a minimum separation twice the distance specified in part (1) of this section.
Where buildings are back-to-back, front-to-front, or front-to-back the minimum distance between any two (2) buildings so situated shall be the greater of thirty-five (35) feet, or the sum of the building heights divided by two (2). However, the average separation between such buildings shall not be less than forty (40) feet.
(b) When buildings arranged in a lineal form are staggered by a minimum offset of fifteen (15) feet or where the buildings are arranged to form an angle greater than fifteen (15) degrees end-to-end, the lineal standards shall not be applied.
(3) Special building orientations: When the plot is five (5) acres or more in size abutting or across a water body or local street from any RS, RC-6 or RD zoned plot, multifamily buildings two (2) or more stories in height shall be oriented so as to not create a massive wall of buildings abutting or facing the RS, RC-6 or RD zoned plot. The multifamily development may achieve this by utilizing site planning techniques such as varying the orientation of the buildings, staggering the setbacks of buildings, rotating the angle of buildings, enhanced buffering and tree planting, providing varying heights in the elevations of buildings, increasing the setback distance over and above the minimum setback included in this chapter or creating an interface of lower height buildings between the plot line and any higher buildings.
The RM development shall locate any game courts in an area which is not directly adjoining or across a water body from any RS, RC-6 or RD-8 zoned plot unless it is impractical, as determined by the development services director, or the multifamily development employs other site planning criteria such as increased and staggered plantings to reduce noise.
(4) Variations in building height.
(a) For buildings of two (2) or three (3) stories in height and not exceeding one hundred (100) feet in length, at least fifteen (15) per cent of the roof line shall have a variation in height, or an average variation in height, of at least five (5) feet.
(b) For buildings of two (2) or three (3) stories in height and in excess of one hundred (100) feet in length, at least two (2) portions of the building shall have a variation in height, or an average variation in height, of at least five (5) feet. The combination of said required variations in height shall amount to not less than fifteen (15) per cent of the length of the building.
(c) For buildings of four (4) or more stories in height at least fifteen (15) per cent of the roof line shall have a variation in height, or an average variation in height, of at least ten (10) feet.
(5) Variations in building facade.
(a) For buildings not exceeding one hundred (100) feet in length, at least fifteen (15) per cent of the building face shall have a variation in setback of at least five (5) feet.
(b) For buildings in excess of one hundred (100) feet in length, at least two (2) portions of the building shall have a variation in setback of at least five (5) feet. Variations of less than five (5) feet shall not count toward this requirement. The combination of said required variations in setback shall amount to not less than fifteen (15) per cent of the length of the building.
