The practice of topping and/or other especially destructive maintenance practices such as severely trimming trees in public streets is strictly prohibited. "Severely trimmed" shall mean the cutting of the branches and/or trunk of a tree in a manner which will substantially reduce the overall size of the tree area so as to destroy the existing symmetrical appearance or natural shape of the tree in a manner which results in the removal of main lateral branches leaving the trunk of the tree in a stub appearances. The standards identified in the ANSI A300 standards describe trimming methods, which will give maximum benefits to both trees and people and are incorporated herein by reference. These specifications and methods shall be made available from the Tree Program Supervisor. (Ord. No. 2007-04, 3-21-07)
