The purpose of the Agricultural Zone is to encourage and protect productive farming and agricultural practices. The growth of large trees and shrubs adjacent to the Agricultural Zone may result in excessive shading and, therefore, reduce the growth of valuable crops. Therefore, no tree or shrub which may attain a height of 20 feet or more shall be planted or allowed to grow within 10 feet of any lot line which abuts an area within an Agricultural Zone.
