Trees planted in Type III landscaped areas along street frontages must have a minimum spread of 10 feet and a minimum height of 20 feet at maturity, unless a lower height is required under power lines. Trees to be planted under overhead electric power lines shall be species recommended in Snohomish County PUD No. l's Tree Book, Puget Sound Energy's Energy Landscaping or an alternative approved by the Planning Director. If the species planted is expected to be less than 20 feet high at maturity, the planning director may require that additional trees be planted. Trees that do not meet these standards, such as palm trees and Thuja occidentalis `emerald green,' may only be permitted for a portion of the landscaping through the modification process in subsection 35.070.A.5 when the proposal includes superior design quality, and increases the number of trees provided. 2.
