§ 97.13  TREE PRESERVATION.
   (A)   In order to protect existing trees intended for preservation during the development’s construction the following plans of action must be adhered to. All developers and construction firms must place substantial barriers around the tree at or beyond the drip line of enclosed trees. No machinery, tools, chemicals, or temporary deposits may be permitted within the barriers nor may any notice or other objects be attached to protected trees. No burning may take place within 500 feet of preserved trees. The barriers are to remain in place until after the completion of all heavy construction on the site. Tree protection procedures and specifications in the Arboricultural Specifications Manual must be adhered to.
   (B)   Significant changes in grading or water flow which would adversely affect preserved trees must be avoided or mitigated through protective measures.
   (C)   The Urban Forester may substitute alternative means in lieu of the required barriers where appropriate to specialized circumstances.
   (D)   These restrictions shall not be interpreted as applying to the public utilities or utilities subcontractors doing routine utility work. However, public utilities and their subcontractors must take reasonable care to protect trunks, branches, and roots of existing trees and shrubs.
   (E)   It shall be unlawful for any person to fasten or attach in any way to any defined street tree any rope, wire, sign, poster, handbill, or other object.
   (F)   It shall be unlawful for any person in any other way to injure, deface or permit any animal to injure or deface any street tree.
