(A) Purpose. The purpose of this subchapter is to promote and protect the natural beauty of the town and to encourage better care of trees and vegetation within the town on both public and private property. It is also of utmost importance to identify and protect trees deemed historic and of great value. The value placed on these trees should be based upon the following criteria: age; size; species; historic significance; ecological value; aesthetics; and location. A list of identified trees can be found with the Zoning Administrator and this list may be updated on a regular basis. This chapter will establish a viable tree management program to be administered by the Planning Board, who will act as a Tree Board until the town deems it necessary to adopt a separate Tree Board. Support and participation in the Tree City USA Program will help guide and support the Tree Board. Lastly, and of utmost importance, this program will educate the public to the importance of protecting trees; along with the benefits they provide to our environment.
