Planting materials may include lawn, shrubs, flowers, decorative rock, bark chips, and/or deciduous and evergreen trees.

Existing vegetation may be incorporated into the landscape design as set forth in 17.45.090 and shall be considered in lieu of new plantings, provided that it contributes to achieving the purpose of this Chapter. The installation of low water use landscaping is encouraged. (Ord. 03-33 §19, 2003; Ord. 87-9 §1, 1987).
