In order to encourage greater flexibility in design, more attractive arrangements of buildings and greater utilization of open spaces, yard regulations for multifamily dwellings are hereby established for single development and for locating several buildings within a group development.
The yards of multifamily buildings shall be attractively landscaped and related to the space within the dwelling units as well as the yards. Buildings shall be arranged so as to assure privacy between adjacent buildings and intersecting wings of buildings, and from streets and parking and recreation areas, in accordance with the following:
(a) Terms used in this section are defined as follows:
(1) Cluster development: A development which utilizes the design technique which concentrates buildings in specific areas on the site, allowing the remaining land to be used for recreation, common open space and the preservation of natural areas and environmentally sensitive features. This type of development shall not be governed by the formulas and restrictions listed in subsections (b) through (j) hereof. Yard regulations for cluster developments are listed in Section 1270.32.
(2) End or secondary wall: Any exterior wall of a multifamily building, other than a main wall, containing secondary windows of a dining or sleeping room, principal or minor windows of a kitchen or bathroom, or no windows.
(3) Group development: A development of more than one multifamily building on a parcel planned as a unit and coordinated with the surrounding neighborhood.
(4) Main wall: Any exterior wall of a multifamily building containing the principal windows of a living, dining and/or sleeping room or rooms.
(5) Overlapping walls: That portion of the exterior walls which are directly opposite, when two buildings that are parallel, or within thirty degrees of being parallel, face each other across an open yard or court.
(6) Single development: A development of one multifamily building on one lot coordinated with the surrounding neighborhood and fronting on a dedicated street.
(b) The distance between facing and overlapping buildings or parts thereof in a group development of multifamily buildings shall vary in direct relation to the length and height of buildings. Such minimum distance shall be determined by the formula,
Minimum Distance = LA + LB + HA + HB
F
The elements of the formula are shown in Illustration E, as follows:
ILLUSTRATION E: YARD REGULATIONS FOR MULTIFAMILY DWELLINGS
(1) Minimum distance: The required minimum horizontal distance between any wall of building A and the nearest wall of building B or the vertical prolongation of either.
(2) LA: The total length of building A which, for the purposes of the formula, is defined as the maximum length of the portion or portions of any wall or walls of building A from which lines drawn perpendicular to the face of such wall or walls will intersect any wall of building B.
(3) LB: The total length of building B which, for the purposes of the formula, is defined as the maximum length of the portion or portions of any wall or walls of building B from which lines drawn perpendicular to the face of such wall or walls will intersect any wall of building A.
(4) HA: The height of building A.
(5) HB: The height of building B.
(6) F: The divisor factor.
In the RM-D and SC Districts, the division factor is three and a half (3.5). However, the minimum distance between any two main walls of separate buildings shall be forty feet.
(c) Minimum distances in angular arrangements of thirty to sixty degrees are determined by the formula,
Minimum Distance: 2LB + HA + HB - K
F
The elements of the formula are as defined above and are shown on Illustration E. "K" in the formula varies as the sine of 2N where N is the angle from building B to building A or extensions thereof.
Where n is K equals
(degrees) (feet)
30 to 34 10
35 to 39 20
40 to 50 25
51 to 55 20
56 to 60 10
In the RM-D and SC Districts, the division factor, "F", is four and a half (4.5).
(d) Minimum distances between walls of court arrangements shall be determined by applying the formula set forth in subsection (b) hereof to each set of facing walls. In the arrangement of parallel walls with offset sections, the distance between the corresponding parallel walls shall be determined by such formula. The elements of the formula are shown on Illustration E. In the RM-D and SC Districts, the division factor, "F", is three and a half (3.5).
(e) The minimum horizontal distance between non-overlapping walls where walls of two buildings do not directly face each other or do not overlap (that is, where lines drawn perpendicular from the face of any wall of any one building will not intersect the face of any wall of another building), shall be not less than one-half of the combined heights of the two buildings. Such minimum distance shall be determined by the formula,
Minimum Distance = HA + HB
2
(f) The distance between a building and boundary lines of a multifamily building or part thereof, in a single development or group development, and any side or rear lot line of the parcel or development area, shall vary in direct relation to the length and height of the building.
Where the building is parallel to the lot line, such minimum distance shall be determined by the formula:
Minimum Distance = 2(LL) + HA
F
Where the building is at an angle to the lot line, the minimum distance shall be determined by the formula:
Minimum Distance = 2(LL) + HA - K
F
The elements of said formula are shown on Illustration E and defined as follows:
(1) Minimum distance: The minimum required horizontal distance between any wall of a building and the nearest side or rear lot line, or boundaries of the parcel or development area.
(2) LL: The maximum length of the side or rear lot line which can be intersected by lines drawn perpendicular from the face or faces of any wall or walls of the building.
(3) HA: The height of building A.
(4) K: It varies as the sine of 2N, where N is the angle from the lot line to the building. The value of "K" is set forth in subsection (c) hereof.
(5) F: The division factor. Where the building is parallel to the lot line, the division factor for the RM-D and SC Districts is three. Where the building is at an angle to the lot line, the division factor for the RM-D and SC Districts is four.
(g) For townhouse dimensions, a unit of a townhouse shall be not less than twenty-two feet in width, and any main or longitudinal wall of a sequence of townhouse units shall not exceed 132 feet in length without a ninety degree offset of at least ten feet, and the aggregate length of any wall, including its offsets, shall not exceed 176 feet in length.
(h) In the use and design of yards, the required yards set forth in this section shall be attractively landscaped and may be used for driveways, pedestrian walks and passive recreation areas. If, however, courts between buildings are used for parking areas or playgrounds, the distances between buildings shall be increased by the dimensions of such intermediary facilities. The site shall be designed so that entrances to all buildings shall be located not more than 300 feet from the accessory parking area, the distance to be measured along pedestrian walks.
(i) Where two or more multifamily buildings are planned as a unit on a single parcel, submission of development plans shall follow the procedure outlined in Section 1270.30.
(j) The diagrams in Illustration E indicate the regulations and planning criteria set forth in this section and constitute a part of this Zoning Code.
(Ord. 89-210. Passed 2-6-90; Ord. 93-19. Passed 2-2-93.)
The required yards surrounding an existing building shall not be separated in ownership from that portion of the lot upon which the building is located, and no part shall be considered as providing a required yard for any other existing building on the same or on an adjacent lot. A yard shall not be reduced to less than the required dimensions for the district in which it is located by enlarging an existing building, and a yard of less than the required dimensions shall not be further reduced in any manner. Every required yard shall be open and unobstructed from the ground upward except for accessory buildings as set forth in Section 1270.12 and projections into yards as set forth in Section 1270.13.
(Ord. 89-210. Passed 2-6-90.)
Where fifty percent or more of the aggregate street frontage between two successive intersecting streets is occupied by buildings of the type and use permitted in the district before the effective date of this Zoning Code or any amendment thereto, with a front yard setback of more or less than required by this Zoning Code, the minimum front yard for new buildings or additions to existing buildings shall be the average setback distance of existing buildings located within 100 feet on either side of a given lot. However, the depth of the front yard resulting therefrom shall be not less than twenty percent of the dimensions specified in the schedule set forth in Section 1270.05.
(Ord. 91-72. Passed 5-8-91.)
Where side yards are narrower than required for the district in which the building and lot are located, which building and lot were owned separately from all other tracts of land on the effective date of this Zoning Code or any amendment thereto, and are still so owned, the building may be maintained or altered but may not be enlarged in width until the total width of the side yards complies with this Zoning Code.
(Ord. 89-210. Passed 2-6-90.)
The depth of the front yard on a corner lot shall be not less than the required setback from the front lot line. The width of the side yard on the side street shall be not less than twenty percent of the width of the lot at the building line but not less than one-half of the depth of the front yard required for the adjoining lot which abuts a side street, unless shown otherwise on the Zoning Map.
(Ord. 89-210. Passed 2-6-90.)
The specific yard regulations set forth in this chapter may be modified by the Board of Zoning Appeals in accordance with standards established in Section 1264.08 where the regulations cannot be complied with reasonably as a result of the irregular shape of a lot or for topographical reasons.
(Ord. 89-210. Passed 2-6-90.)
