Collierville City Zoning Code

TREE PROTECTION

AND GRADING

§ 151.265 PURPOSE AND INTENT.

   (A)   The purpose and intent of this subchapter is to promote the health, safety and public welfare of the inhabitants of the Town of Collierville by preserving or increasing the tree canopy coverage within the community. This subchapter is based on the premises that trees are part of our heritage and our future and that they are an essential part of the quality of life within the Town.
   (B)   The standards herein are established in order to create greater human comfort by providing shade, to cool the air and otherwise temper the effects of summer heat, to restore oxygen to the atmosphere, to reduce glare and noise levels, to promote clean air quality by increasing dust infiltration, to improve surface drainage and minimize flooding, to ensure that activities in one area do not adversely affect activities within adjacent areas, to emphasize the importance of trees as a visual screen, to beautify and enhance improved and undeveloped land, to maintain the ambience of the Town and to ensure that tree planting and removal does not reduce property values, all of which aide in protecting the health, safety and general welfare of the Town.
   (C)   The standards herein are established in order to provide proper oversight for land development and construction activities, as they are a primary source of stormwater pollution, and can cause significant environmental damage to the streams and waterways of the Town if not properly managed.
