The plan itself shall also depict a method of physically delineating private lots from common open space areas by the use of fencing, sections of fencing, easily visible corner posts or other monuments or methods acceptable to the Board of Supervisors.
(b) 
Provision for ownership and maintenance of common open space shall be made in a manner so as to ensure its preservation. This shall be accomplished in one of the following ways:
(1) 
The developer shall offer the common open space for dedication for public use and maintenance, if required by the Township. However, the Township need not require that the common open space be dedicated, nor accept a dedication of the common open space if offered.
(2) 
With permission of the Township, and with appropriate deed restrictions in favor of the Township and in language acceptable to the Township Solicitor, the developer may transfer the fee simple title in the common open space, or a portion thereof, to a private, nonprofit organization, among whose purposes is the conservation of open space land and/or natural resources, provided that:
A. 
The organization is acceptable to the Township and is a bona fide conservation organization with a perpetual existence.

The conveyance contains appropriate provision for proper retransfer or reverter in the event that the organization becomes unable or unwilling to continue to carry out its functions.
C.

C.S. 3101 et seq. If such an organization is created, the deeds and agreements of sale for the common open space and for all individual lots within the tract shall contain the following requirements in language acceptable to the Township Solicitor:
A. 
Such organization shall not dispose of the common open space by sale or otherwise except to the Township or other governmental body, unless the Township has given prior approval.

B. 
The organization and all lot owners within the development shall agree to be bound by the provisions of Section 705(d)(2) and (3) of the Pennsylvania Municipalities Planning Code, Act of July 31, 1968, P.L. 805, No. 247, as amended, 53 P.S. 10705(d)(2) and (3), relating to Township maintenance of deteriorating open space, and providing for the ability of the Township to access and lien the properties within the development.

The Township may require the formation of a reserve fund to cover capital improvements to the common open space.
[Ord. 246. Passed 12-22-1987. Ord. 377. Passed 9-25-2000]
In order to provide for increased preservation of open space, a developer of a tract within an A-1 Residential District may request as a conditional use, in accordance with Section 1298.07, that the tract be permitted to be developed at a higher density if there is preservation of open space in addition to that required by Section 1258.09. All developments under these density bonus provisions shall meet the following requirements and shall comply with all applicable requirements for cluster developments provided in this chapter, and all common open space shall comply with Section 1258.11.
(a) 
Use regulations. In a cluster development with density bonus, single-family detached residential dwellings, open space and recreational areas and structures shall be permitted. All residential uses shall be subject to the general regulations applicable to an A-1 Residential District, except as specifically modified by Sections 1258.09 through 1258.11 and this section.
(b) 
Density regulations. The total number of dwelling units which shall be permitted in a cluster development with density bonus shall be contingent upon the percentage of the gross area of the tract reserved for common open space uses in addition to all undevelopable areas. For every five percent of the gross area of the tract reserved for common open space above the minimum required under Section 1258.09(c) (which consists of ten percent of the gross area of the tract plus all undevelopable land), a corresponding five-percent increase shall be allowed in the density as set forth in Section 1258.10(b) up to the maximum of 1.25 dwelling units per developable acre. The maximum density computed by this method, as set forth in the table below, shall in all cases govern density.
Minimum Open Space
Maximum Density in Dwelling Units Per Developable Acre
15% of the gross area of the tract plus all undevelopable area
1.05
20% of the gross area of the tract plus all undevelopable area
1.10
25% of the gross area of the tract plus all undevelopable area
1.15
30% of the gross area of the tract plus all undevelopable area
1.20
35% of the gross area of the tract plus all undevelopable area.
1.25
(c) 
Development standards. The minimum area of any lot and the minimum dimensions of lot width at the building line, front yard, side yards and rear yard which shall be permitted in a cluster development with density bonus shall be contingent upon the percentage of the gross area of the tract reserved for common open space uses in addition to all undevelopable areas. For every 5% of the gross area of the tract reserved for common open space above the minimum required under Section 1258.09(c) (which consists of ten percent of the gross area of the tract plus all undevelopable land) to be reserved for common open space, to a maximum of 35% of the gross area of the tract plus all undevelopable area, a corresponding decrease shall be allowed in the minimum area of any lot and the minimum dimensions for lot width at the building line, front yard, side yards and rear yard as set forth in Section 1256.10. The yard required by Section 1256.10(e)(4) shall not be reduced under this section.
(d) 
Historic or cultural resources. In a cluster development with density bonus under this section, as a conditional use, the maximum permitted tract density may be increased by 5% of the 1.00 dwelling unit per developable acre, in addition to the increase set forth in subsection (b) hereof, where the tract contains one or more Township historic or cultural resources, and such Township historic or cultural resources shall be preserved as a part of the development plan.
A Township historic or cultural resource shall be defined as a site or structure listed in the National Register of Historic Places, the Pennsylvania Historic Resources Survey, the Montgomery County Inventory of Historic and Cultural Resources, a listing of historic and cultural resources compiled by the Board of Supervisors or the Planning Commission, or other appropriate documentation, or a site or structure seeking listing as a historic resource from any or all of the above listings.
[Ord. 246. Passed 12-22-1987]
A cluster development or cluster development with a density bonus shall be available as a conditional use in an A-1 Residential District. All applications for this conditional use shall be made in accordance with the provisions of Section 1299.07. Such applications shall be subsequently considered as a subdivision and/or land development application and shall follow the procedures set forth in the Subdivision and Land Development Regulations.
