§ 178-6. Planting of trees.

The planting of tree(s) shall be in accordance with the specifications of the landscape nursery from which the tree(s) is purchased or of a licensed design professional. Lacking specifications, the planting of trees shall be as follows:

A. 

For every inch of tree diameter planted, there shall be a minimum of nine square feet of pervious soil surrounding the tree trunk, to allow water and air to the tree roots. For a minimum two-inch-diameter tree, therefore, there shall be a minimum of 18 square feet of pervious soil surrounding the tree trunk.

B. 

No tree shall be planted closer to another tree, existing or proposed, with less than 20 feet of horizontal spacing from center of tree. In the event that a landscape nursery from which the tree is purchased or the design professional recommends a greater horizontal spacing, such spacing shall govern.

C. 

Trees shall be planted only during the period from September 1 to May 15.
