6.4.5.   
   A.   Application
   A is required in accordance with the applicable as provided in Tables 6.3-1 through 6.3-7. The minimum required width of the for each is based on the zoning classification of the (s) along each individual .
   B.   Measurement
      1.   The width of the is the distance measured horizontally from a specified point to the face of each exterior wall at the wall’s highest point. The specified point is the when it is an interior . Along a , the specified point is described in Section 6.4.5.C, . (See Figure 6.4.5-B & -C.)
      2.   A vertical structural member(s) (i.e., post, column, dormer wall) supporting a roof extension from the principal is considered a wall for applying requirements.
      3.   The may have different widths at various points along the same , because the width is measured to the face of each vertical exterior surface of the .
      4.   On cul-de-sac and eyebrow front , the minimum depth may be measured from a straight line drawn between the front corners, rather than measured directly from the curved front , except as provided in Section 6.4.5.C.2.b, and in Single- and Duplex . In no case, however, shall the minimum be reduced in excess of 50% by this alternative measurement. (See Figure 6.4.5-A.)
      5.   Where an unbroken section of a wall or a is not parallel with the , the required may be applied to the average width; however, such shall not be narrower at any point than half the required width, nor narrower at any point than three feet. (See Figure 6.4.5-A.)

   C.   
   The width is determined as provided below or unless special zoning requirements dictate a greater distance or different point of measurement.
      1.   
         a.   Within , the minimum required front is 20 feet or one and one-half the of the proposed wall (H), measured from the , whichever is greater, up to a maximum of 90 feet.
         b.   Where a abuts more than one , the owner chooses which is the front . From other than the front , the is ten feet.
      2.   Developing Areas
      Within developing areas, the minimum required is determined by the type of proposed and the projected of the and is required as follows:
         a.   All Except and Garages in Single- and Duplex
         A minimum is required between a and an as determined in Table 6.4.5.C-I, except for and in single- and duplex , which are determined in Section 6.4.5.C.2.b, and in Single-Family and Duplex . The is based on the projected ADT. Of the two or more distances listed in Table 6.4.5.C-I for each ADT range, the which provides the greatest distance from the is required. (See Illustration 6.4.5-D.)

   H = The of the proposed exterior wall.
1 In all circumstances, the greater resulting from the alternate measurement is required.
2 The is measured from the back of existing curb or future curb location.
3 The is measured from the or from the nearest edge of the or future location.
4 The is measured from the outside edge of the nearest .
         b.    and in Single- and Duplex
         For , , or similar in single- or duplex residential on individual , a minimum is required using one of the following alternatives: (See Figure 6.4.5-E.)
            (1)   A minimum of 19 feet from the back of to allow sufficient space for a motor vehicle to be parked in front of the or is required as follows:
               (a)   Eighteen feet (the length of a standard parking space) must be provided in front of the or and measured so that the full 18-foot parking space is available for parking on- ; and,
               (b)   The 18-foot parking space shall be no closer than one foot from back of of the from which access is gained.
               (c)   Modifications to the structural and parking space length requirements of this section for only in single- and duplex may be granted in accordance with Section 3.11.1, Design Option.
            (2)   A minimum of one foot from the back of of the from which access is gained, is required if all of the following apply:
               (a)   The from which access is provided has a projected ADT of 140 vehicle trips or less;
               (b)   The is measured so that the and the parking space within that are located completely on- and do not encroach into the one-foot ; and,
               (c)   The distance between the pavement edge and the is eight feet or less. The purpose of this requirement is to discourage motor vehicle that would block the pedestrian area or overhang onto the .
         c.   When the is measured from the nearest edge of , back of , or future , and there is no existing or proposed , the nearest edge of the pedestrian and utility area to the ’s is used as the point of measurement for the . The location and width requirements for pedestrian and utility areas are found in the Section 7, Pedestrian Access, of the Technical Standards Manual.
         d.    shall not be less than the minimum width of the requirements of Section 7.6.4.C, Landscape Borders.

   D.   Exceptions
   Encroachment into the required is allowed as follows.
      1.   Interior
      Along interior , the following may extend two feet into the , provided the side or rear yard is not reduced to less than three feet:
         a.   Chimney;
         b.   Roof overhang; or,
         c.   Bay window.
      2.   
      Along , the following may extend into the required width as provided below.

            (2)   Roof overhang;
            (3)   Stairs;
            (4)   Bay window; or,
            (5)    .
         b.   On any corner , no fence, , object, or planting shall be erected or maintained to interfere with the sight visibility triangle provisions set forth in the Technical Manual.
      3.    within Front Yards
         a.   Architectural features that are part of a may up to four feet into required . Such architectural features include, but are not limited to, overhangs, moveable insulating walls and roofs, detached solar collectors, reflectors, and piping.
         b.   A wall or fence not over six feet high may be erected within the limits of a .
      4.   Adjacency to Certain Nonresidential Uses in Residential
      For in a nonresidential to a residential , the may be modified to equal the nonresidential use to nonresidential standard for the ’s based upon a finding by the Zoning Administrator that one of the following applies:
         a.   The residential is a:
            (1)    use;
            (2)    ; or,
            (3)   Easement for floodplain, drainage, or utility easement.
         b.   For annexed properties only, the residential is used for commercial, industrial, storage, utility, or warehousing purposes at the time of annexation.
