A tree contractor shall have on staff an arborist certified by the International Society of Arboriculture to be qualified to prune, treat, or remove street or public trees within the City. The certified arborist must oversee all pruning work and certify that all work meets the City’s pruning specifications. Nothing in this section shall prevent the employees of public agencies who are not certified arborists from pruning trees on the grounds of those public agencies. (Ord. 165, passed 10-8-2019)
