Other required vegetation and shall be distributed within the buffer as appropriate to the function of the buffer. [B] Where an adjacent existing development is designed for solar access, the Planning Director may allow understory trees to be substituted for any shade trees where necessary to ensure such solar access. [C] Berms may be used in conjunction with shrubs or fences or walls atop them to achieve required screening. Berms within a buffer shall comply with the standards of Section 5.12.3.E, Berms. [D] Buffers, with the exception of Type J, Option 2, and Type K, Option 2, shall not be located on single-family detached, duplex, attached, or manufactured home dwelling lots. Notes: [1] Fences or walls within a buffer shall comply with the standards of Section 5.14, Fences and Walls [2] Trees in streetyard buffers shall be of species and varieties appropriate to their location next to roadways and sidewalks. (See appropriate street tree species and varieties listed in the Administrative Manual.) [3] A planting strip located between the back of the curb and a sidewalk shall be at least six feet wide. Where such a planting strip does not exist or is impractical to provide, the Planning Director may allow the trees to be provided within tree pits that are at least 25 square feet in area and located adjacent to the back of the curb.
