   Notes related to table.
      (1)   Architectural features. Bay windows, window sills, belt courses, cornices, eaves, overhanging eaves, and other architectural features may project into a required side yard not more than two inches for each one foot of width of the side yard, and may extend into any front or rear yard not more than 24 inches.
      (2)   Terraces and porches. Open paved terraces and open porches may project into a required rear yard up to ten feet, provided that the unoccupied portion of the rear yard has a depth of at least 25 feet.
      (3)   Access drives and walkways. Access drives may be placed in the required front or side yards so as to provide access to rear yards or accessory or attached structures. Further, any walk, terrace or other pavement serving a like function, shall be permitted in any required yard, providing the pavement is no higher than six inches above grade.
      (4)   Unenclosed porches, with or without roof. Unenclosed porches may project into the required 30-foot front yard set-back up to six feet, and shall maintain a minimum side yard setback of three feet. In cases where single-family houses maintain a front yard setback greater than 30 feet, one additional foot of projection shall be permitted per each foot of additional setback outside of the 30-foot requirement; not to exceed a total front porch projection of ten feet.
   (D)   Unobstructed sight distance. 
      (1)   No fence, wall, structure, or planting shall be erected, established, or maintained on any lot which will obstruct the view of drivers in vehicles approaching an intersection of two roads or the intersection of a road and a driveway (see Appendix B, Illustration 9, Unobstructed Sight Distance). Fences, walls, structures, or plantings located in the triangular area described below shall not be permitted to obstruct cross-visibility between a height of 30 inches and six feet above the lowest point of the intersecting road(s).
      (2)   Trees shall be permitted in the triangular area provided that limbs and foliage are trimmed so that they do not extend into the cross-visibility area or otherwise create a traffic hazard. Landscaping, except required grass or ground cover, shall not be located closer than three feet from the edge of any driveway or road pavement within the triangular area.
   (E)   Unobstructed sight area. The unobstructed triangular area is described as follows.
      (1)   The area formed at the corner intersection of two public right-of-way lines, the two sides of the triangular area being 25 feet in length measured along abutting public rights-of-way lines, and the third side being a line connecting these two sides, or
      (2)   The area formed at the corner intersection of a public right-of-way and a driveway, the two sides of the triangular area being ten feet in length measured along the right-of-way line and edge of the driveway, and the third side being a line connecting these two sides.
   (F)   Lots adjoining alleys. In calculating the area of a lot that adjoins an alley for the purposes of applying lot area and setback requirements, one-half of the width of the alley shall be considered a part of the lot. However, if a portion of the lot is occupied by an alley currently in use (i.e., not vacated), then the area shall not be used in lot area computations related to the landscaping standards.
