A. The pruning and removal of street trees within the Downtown Tree Zone shall be the responsibility of the city, and shall be undertaken at public expense.

B. The planting of street trees shall be subject to the design drawings and specifications developed by the city in May 2014. Specific design drawings and specifications have been developed for trees within the Downtown Tree Zone. Such design specifications may be periodically updated by the city to include specifications such as tree root barriers, watering tubes or structures, tree grates, and removable pavers, and shall graphically describe the proper method for planting trees within the Downtown Tree Zone to minimize the potential for sidewalk / tree root conflict.

C. The city shall adopt implementation measures that cause, through rotation over time, the development of a variable aged stand of trees within the Downtown Tree Zone. In order to implement this policy, the planning director shall authorize, but shall limit, annual tree removal within the downtown to no more than three percent of the total number of existing downtown trees in the Downtown Tree Zone.

D. A street tree within the Downtown Tree Zone may be removed if the planning director determines that the tree is causing repeated and excessive damage to sidewalks or other public or private improvements or structures. (Ord. 5027 §2, 2017).
