The overall goal of the heritage tree ordinance’s replacement requirement is to ensure continued canopy cover is maintained or increased. Ideally, the replacement tree(s) should replace the removed canopy cover in a period of approximately 15 to 20 years.
Under Municipal Code Section 13.24.090(1), an approved replacement tree list is not provided as site conditions are unknown and will vary from each property. A specified list also limits species diversity. However, below are some examples of replacement tree species that meet the criteria listed above.

In reference to Section 13.24.090(2), applicants may use the following monetary value of the replacement trees to help design their landscape plans for development-related removals:
One (1) #5 container – $100
One (1) #15 container – $200
One (1) 24-inch tree box – $400
One (1) 36-inch tree box – $1,200

One (1) 60-inch tree box – $7,000

In reference to Section 13.24.090 (3) for decisions made under Criteria 1, 2, 3, or 4, the monetary value of a replacement tree correlates with the size of the heritage tree trunk diameter (measured from 54 inches above grade). For every heritage tree proposed for removal, it must be replaced by the following replacement tree requirement:

Any heritage tree with a trunk diameter of greater than 15 inches to 20 inches has a minimum replacement tree requirement of one (1) #15 container. The monetary value is $200.
Any heritage tree with a trunk diameter of greater than 20 inches to 30 inches has a minimum replacement tree requirement of one (1) 24-inch tree box. The monetary value is $400.
