A. 
The purposes of this chapter are to provide proper guidelines and specifications for preserving the natural character of the land and vegetation; to provide regulations for planting trees, shrubs and landscaping in buffer areas, along streets and throughout each development as required by township ordinances; to prevent soil erosion; to enhance the aesthetic nature of each project; to reduce air and sound pollution; to provide visual barriers; to regulate wind control; and to reduce glare and reflection.
B. 
In addition, it is the purpose of this chapter to provide for flexible requirements that recognize changes that have occurred in the field, such as improvements to species. Therefore, an applicant may submit proofs indicating how technological advances in certain species possibly make such trees suitable for use in the township. Conversely, trees which are now acceptable may be unacceptable at some future time due to the introduction of diseases into the area.
