Any public utility required by State statute or regulation to trim or remove trees which may interfere with their facilities shall ensure that their tree trimming activities protect the appearance, integrity and health of the trees to the extent reasonably possible. The public utility shall prepare and maintain a tree trimming schedule to ensure compliance with this provision and to avoid exigent circumstances where tree cutting, trimming or removal is necessary to protect the public safety or continuity of service without regard for the appearance, integrity or health of the trees that planned maintenance would otherwise allow. The public utility shall submit the schedule to the City Manager. Except where exigent circumstances do not permit, the public utility shall give the owner of the property on which the trees are located at least five days advance written notice of the tree trimming. (Ord. 22-99 § 1)
