A. 
It is the intent of this article to provide for modification of lot area, yard and use requirements in certain zoning districts in connection with single-family dwelling development for the purpose of accomplishing the following objectives:
(1) 
To encourage conservation and use of open space in new residential development.
(2) 
To encourage land development which preserves trees and natural topography, prevents soil erosion and promotes the best interests of the Township from an aesthetic, ecological and natural resource standpoint.
(3) 
To encourage attractive arrangements of dwellings by permitting the design and layout of dwellings to be closely related to the physical characteristics of the site in harmony with surrounding tracts.
B. 
The means of accomplishing such objectives shall be made only on the basis of subdivision and/or land development plans approved by the Board of Commissioners which meet the purposes and requirements of this article. It is not intended that every tract of land is adaptable to the purposes of this article, and therefore the Board of Commissioners may disapprove an application upon any tract which, in its judgment, should be developed under the other provisions of this chapter.
[Amended 10-28-1975 by Ord. No. 1613]
C. 
This article is based upon and shall be interpreted in relation to the Comprehensive Plan adopted by the Board of Commissioners.

G. 
There shall be a buffer of 25 feet along all property lines which abut residentially zoned districts which shall not contain any roads, structures, parking areas, etc., and shall be planted in accordance with a plan which shall be approved by the Board of Commissioners at the time of final approval.
