§ 153.535 AREAS TO BE LANDSCAPED.
   The following areas shall be landscaped, and may count toward the total area of site landscaping required by zoning district regulations. The figures contained in this section are for illustrative purposes only and do not imply that the concept illustrated be implemented precisely as shown but rather in a manner consistent with the purpose of these regulations.
   (A)   Required setbacks. All required setbacks in all zones, except for areas used for exit and entry, shall be landscaped.
   (B)   Lot perimeters. Landscape buffers shall be installed and maintained along side and rear lot lines between differing land uses, in accordance with the following standards.
      (1)   Required landscape buffers. Table 153.535-(B)(1), Required Landscape Buffers, shows when a buffer treatment is required, and of what type, based on the proposed and the adjoining use. Only the proposed use is required to provide the buffer yard. Adjoining uses are not required to provide the buffer yard. The type of buffer yard required refers to buffer yard-type designations as shown in Table 153.535-(B)(2), Buffer Yard Requirements. “-” means that a buffer yard is not required unless required by another section of this title.

      (2)   Buffer-yard types. Table 153.535-(B)(2), Buffer Yard Requirements, describes the minimum width, plant materials, and wall requirements for each type of buffer yard. The listed number of trees and shrubs are required for each 100 lineal feet of buffer yard. Trees shall be planted at least 40 feet on center. Natural areas with native vegetation or alternative planting materials which achieve equivalent buffering effects may be approved by the Community Development Director.

      (3)   Width reduction for adjacent landscaped buffer. If an equivalent landscape buffer exists on the adjacent lot, the width of the required buffer may be reduced 50% provided that the abutting property owners have provided a written agreement ensuring the adjacent landscape buffer will be preserved and maintained.
   (C)   Building perimeters. The portions of a multi-family residential, commercial, industrial, or institutional building that front a public street shall have one or more landscape planters installed along a minimum 20% of that building face. The minimum width of the planter shall be three feet. This standard does not apply where a building is located on the front or corner side property line.

   (D)   Flood control channels. A 15-foot wide landscape buffer planted with drought tolerant plants, including a 12-foot wide service road and bike path, shall be provided along the outer edge of flood channel easements. In those cases where a strict compliance with the landscaping requirements set forth in this division may be a hardship on the property owner or the developer thereof, an alternate plan accomplishing the objectives of helping restore the lost environmental value of the Alhambra and Rubio washes and enhancing the washes as scenic community amenities may be submitted for review by the Community Development Director. The Community Development Director shall be authorized to disapprove, approve, or conditionally approve the alternate plan.

   (E)   Parking areas. Parking areas as required by § 153.226, Parking Lot Landscaping and Screening.
   (F)   Parkways and street trees. Protect roots of street trees with engineered soil and provide sufficient space for above and below ground growth. Street trees form the canopy, provide shade, introduce seasonal color and define the street edge. The minimum installed street tree size should be 24-inch box to ensure long term survival of the tree and the ability for the tree to reach mature height rapidly.
   (G)   Unused areas. All areas of a project site not intended for a specific use, including areas planned for future phases of a phased development, shall be landscaped or left in a natural state.
