NOTES TO TABLE 1 - Average size of all lots must exceed 10,400 square feet. 2 - Average width of all lots must exceed 73.5 feet. No two consecutive lots to have widths less than 70 feet. 3 - Buried garages, 480-square foot bonus. Ponding or unbuildable areas shall not exceed 20% of the required lot area. 4 - Square feet of land per unit. 5 - Units per acre. 6 - Alternate, even numbered, lots shall be permitted a 25-foot setback. Corner lot sideyard setbacks shall be 20 feet. * - See § A15-5(A)(2). | |||
(2) Setbacks between multiple dwellings.
(a) The front and rear sides of a multiple dwelling shall have a minimum setback of 50 feet from any side of an adjacent multiple dwelling or a setback equal to the combined height of the adjacent multiple dwellings, whichever is greater, except that in no case shall a setback greater than 75 feet be required. This minimum setback shall be reduced to 40 feet where a horizontal extension of the lines created by the nearest exterior vertical surfaces of adjacent buildings would create an angle of not less than 45 degrees.
(b) Minimum setbacks between adjacent multiple dwellings on sides which are not a front or rear side of either building shall be 20 feet or a distance equal to one-half of the combined height of the adjacent buildings, whichever is greater, except that in no case shall a setback greater than 50 feet be required. This minimum setback shall be reduced to 25 feet where a horizontal extension of the lines created by the nearest exterior vertical surfaces of adjacent buildings would create an angle of not less than 45 degrees.
(3) Maximum impervious surface, see § 155.350.
(4) Screening, see § 155.348.
(5) Landscaping, see § 155.349.
(B) The following requirements are in addition to those in division (A). Where there may be a conflict, the requirements herein shall prevail:
(1) Front setbacks prevailing. Where adjoining structures existing at the time of adoption of this article have a greater setback than that required by this article, the front setback of a new structure shall conform to the prevailing setback in the immediate vicinity. The Building Official shall determine the necessary front yard setback in such cases. In no case shall a building be required to be set back more than 50 feet.
(2) Side and rear setbacks, party walls. Buildings may be excluded from side and rear setback requirements if party walls are used and if the adjacent buildings are constructed as an integral structure. This shall not permit structures closer to single family detached or duplex lots, however, than required under division (A)(1).
(C) The following special performance standards shall be applicable to uses as specified. Where there may be a conflict between these standards and standards required elsewhere, these standards shall prevail.
(1) Within Zone 1, the following provisions apply:
(a) Architectural design. Identical single-family building elevations shall not be permitted on lots directly adjacent to or directly across a street from one another; and
(b) Berms. An undulating sodded berm or berms shall be installed adjacent to any principal or arterial streets. Berm(s) shall provide for an obstruction of horizontal view from the street(s) for a minimum vertical distance of four feet above grade for its entire length and a minimum vertical distance of six feet for no less than 80% of its entire length. Berm(s) shall be subject to the traffic visibility requirements of § 155.335, maximum slope, 3:1.
(2) Within Zone 2, the following provisions apply:
(a) Berms. An undulating sodded berm or berms shall be installed adjacent to all streets or abutting detached single-family lots. Berm(s) adjacent to principal or arterial streets or detached single-family lots shall provide for an obstruction of horizontal view for a minimum vertical distance of four feet above grade for its entire length and a minimum vertical distance of six feet for no less than 80% of its entire length, except that no berm shall be required adjacent to a single-family lot when separated by a ponding area. Berm(s) adjacent to a local access street shall provide for an obstruction of horizontal view from the street(s) for a minimum vertical distance of three feet above grade for its entire length and a minimum vertical distance of four feet for no less than 80% of its entire length. All berm(s) shall be subject to the traffic visibility requirements of § 155.335, maximum slope, 3:1;
(b) Trees. Along berm(s) specified in subsection (a) above, Marshall Seedless Ash and Norway Maple trees shall be required. Trees shall have a caliper of two inches, balled and burlapped. Trees shall be placed at intervals along the berm of not more than 25 feet apart. Plantings shall be alternated such that no more than two of the same species will be located adjacent to one another. Plantings shall be made only in the toe area of any berm’s slope; and
(c) Shrubs. Associated with each tree in subsection (b) above, there shall be a minimum of two Junipers Manxi planted. The plantings to be a minimum size of 24 inches, balled and burlapped.
