It is unlawful for any person to remove, or in any way injure or deface, the trees, shrubs, plants, tree stakes or tree guards in or upon any public right-of-way within the City without first having obtained a written permit therefor from the Department of Public Works, setting forth the conditions under which the work may be done. Such permit shall specifically describe the work to be done, and shall be void after 30 days from the date of issuance. The cost of removal of any tree, palm, shrub or plant for the benefit and convenience of any property owner shall be paid for by such property owner. (Ord. 1205 § 2, 1969; prior code § 27.809).
