[Added 11-2-1979 by Ord. No. 4-56]
A. 
It is the purpose of this article to encourage and promote rural open space and conservation uses in the R-6 Zone, while also permitting low-density single-family and multifamily residential development which will blend with existing uses and perpetuate the rural atmosphere of the area. Accordingly, the district incorporates a density standard which, among other things, provides for farm and low-density dwelling uses, discourages isolated higher density development but permits rural cluster subdivisions, retirement communities and rural attached dwelling development as conditional uses and facilitates the conservation of agricultural and woodland areas, surface and underground water supplies and the control of soil erosion, and surface water flooding.
B. 
In the R-6 Agricultural/Rural Residence District, the following regulations shall apply.
[Amended 9-4-1985 by Ord. No. 4-83]
A building may be erected, altered or used and a lot or premises may be used or occupied for any one of the following purposes and no other:
A. 
Any use permitted by § 160-60 by right, by special exception or as an accessory use, as therein specified, subject to applicable standards, criteria and special regulations specified in Article XII.
B. 
As a permitted use, a golf course residential community consisting of any combination of one or more single-family attached or detached dwellings constructed on or adjacent to a golf course and which are an integral part of the overall development of the tract of which a golf course is a part.

Special regulations for preservation of historic structures. In a rural cluster subdivision with historic preservation, the conditional use application shall include a preservation plan which shall specify, at a minimum, the identification of historic structures proposed to be preserved; the uses proposed for all historic structures; a description of any repairs or alterations necessary to preserve and utilize the historic structures as proposed; and plans for any new structures or additions to existing structures proposed as part of the historic preservation. The conditional use presentation shall additionally include proposed language for a preservation easement to be granted to the Township for the purpose of confirming, as a covenant running with the land, the requirements of this section for historic preservation as well as the Township's conditional right to dedication set forth in Subsection D(2) below. The historic structure or structures to be preserved shall also be subject to the following regulations:
(1) 
Physical preservation of the historic structure or structures. Historic structures deemed worthy of preservation by the Whitpain Township Board of Supervisors shall not be demolished or moved if such actions are prohibited in the conditional use decision granting permission for the rural cluster subdivision with historic preservation. Any change or amendment to the requirements for historic preservation set forth in a conditional use decision under this section shall be permitted only upon subsequent conditional use application and decision for such purpose. The owner of an historic structure preserved under this section may make such interior changes as are necessary to effectively utilize the structure and may make such exterior changes as do not, in the opinion of the Board of Supervisors, impair the architectural integrity of the facade of the historic structure.
(2) 
Township's conditional right to dedication. In exchange for the increase in density which this section represents over the density permitted in a rural cluster subdivision without historic preservation, the Township shall have the right, but not the obligation, to require dedication to the Township of any historic structure or structures on the property which are not proposed to be preserved on a conditional use plan and application under this section. Once a rural cluster subdivision with historic preservation receives conditional use approval and subdivision approval, no structure proposed to be preserved by such plan may thereafter be demolished for any reason except upon subsequent conditional use application and further provided that the Whitpain Township Board of Supervisors shall have received an offer, at no cost, of dedication of such structure which may be accepted by the Supervisors at any time within a period of three months from the date on which such offer was received. Any such deed of dedication to the Township shall restrict the use of the land so dedicated to historic preservation or passive open space. Any conditional use approval for a rural cluster subdivision with historic preservation shall include a condition that the Township's conditional right to dedication as set forth in this subsection shall be reflected in a deed restriction recorded against the historic preservation portion of the tract.
(3) 
Minimum lot size for historic preservation. The minimum lot size for any lot or lots on which an historic structure or structures is or are proposed to be preserved shall be 1/2 acre.
