(1) Off-street parking areas shall have at least 10 square feet of interior landscaping for each parking space, excluding those spaces abutting a perimeter for which landscaping is required by any other section of this code, and excluding all parking spaces that are directly served by an aisle abutting and running parallel to such a perimeter. Additionally, other vehicular use areas shall have one square foot of landscaped area for each 100 square feet of paved area or fraction thereof. Where the property contains both parking and other vehicular use areas (off-street loading space, for example), the two types of areas may be separated for the purpose of determining the landscape requirements of the other vehicular use area. Each separate landscaped area shall contain a minimum of 50 square feet and shall have a minimum dimension along any one side of five feet. Each separate landscaped area shall include at least one tree having a clear trunk of at least five feet, with the remaining area landscaped with shrubs, ground cover, or other vegetative material not to exceed three feet in height.

(2) The total number of trees shall be not less than one for each 100 square feet or fraction thereof of required interior landscaped area. Such landscaped areas shall be located in such a manner as to visually divide and break up the expanse of parking.

(3) Where irrigation systems are proposed, the location and coverage of the sprinkler heads shall be carefully considered, so as not to deposit water from the irrigation system directly onto any impervious surface.

(4) In vehicular use areas where the strict application of this section would seriously limit their function, the required landscaping may be located near the perimeter of the paved area. Such required interior landscaping which is so relocated shall be in addition to the perimeter landscaping requirements enumerated in SMC 17.145.100 and this section.
