[Added 8-21-1980 by Ord. No. 4-61]
In expansion of the statement of community development objectives contained in Article III, § 160-6, it is hereby declared to be the intent of this article with respect to the R-7 Residential District to establish reasonable standards of performance and promote the desirable benefits which single-family detached dwellings will have in those areas of the Township that are presently served or planned to be served by public sewer and water. Furthermore, it is the intent of this article to encourage a creative approach to the use of land, a more desirable visual character in residential areas, the creation of usable open space corridors throughout the Township and more efficient development patterns in terms of roads and utilities where applied for as a conditional use to the Board of Supervisors. Specifically, this article is intended to provide for a variation in the normally required lot sizes in the R-7 Residential District so that desirable open space, tree cover, historic sites, recreation areas, scenic vistas, stream valleys or other lands for public purposes are preserved within these developments for the benefit of the residents of the development and in furtherance of the general welfare of Whitpain Township.
[Amended 8-16-1993 by Ord. No. 4-137]
In an R-7 Residential District, a building may
be erected, altered or used and a lot may be used or occupied for
any one of the following uses:
A.
One single-family detached dwelling.
[Amended 3-15-2011 by Ord. No. 4-231]
The following dimensional requirements shall apply for each lot, except as provided in §§ 160-85 and 160-85.1:
A.
A lot area of not less than 15,000 square feet and
a lot width of not less than 100 feet at the building line shall be
provided for every building or other structure erected or used in
this district.
C.
Accessory uses.
[Amended 8-18-2015 by Ord. No. 4-240]
(1)
An accessory building or structure having a maximum height of 10
feet, but not exceeding 15 feet measured from grade to the highest
point of such building or structure may be erected in the rear yard
only, but no closer to the side or rear line of the lot than five
feet. The height of the accessory building or structure and the maximum
dimension from grade to the highest point may be increased an additional
one foot for each, additional two feet of required setback from both
the side and rear lines of the lot, to a maximum accessory building
or structure height of 16 feet, but not to exceed 25 feet measured
from grade to the highest point of the building or structure. All
measurement from grade to the highest point of the building or structure
shall include any chimneys, spires, towers, elevator penthouses, tanks
and similar projections.
(2)
Accessory structures are limited to 20% of the area of the rear yard.
No dwelling shall be constructed without adequate
sanitary facilities, which shall be considered to exclude outdoor
toilets.
In certain cases, some reduction in lot sizes
along with preserved open space may be approved when applied for as
a conditional use to the Board of Supervisors and when the following
conditions are met:
A.
Prerequisites for development. The following necessary
conditions must be satisfied by an applicant seeking to develop under
this article before the Board of Supervisors will consider preliminary
plan approval under this section:
(1)
Tract size. The tract of land to be developed shall
not be less than 25 developable acres in area.
(2)
Ownership. The tract of land to be developed shall be in one ownership or shall be the subject of an application filed jointly by the owners of the entire tract, and it shall be agreed that the tract will be developed under single direction in accordance with an approved plan. Transfer of ownership prior to the commencement of construction shall also render the conditional approval required in Subsection A(4) herein void; provided, however, that if such transfer is to a corporation whose stockholders are the same as the legal or equitable owners of the tract who have requested the conditional approval, such transfer shall not void such conditional approval.
(3)
Natural and man-made amenities. At least 10% of the
developable acreage of the tract to be subdivided must contain any
one or combination of the following natural and man-made amenities:
(b)
Slopes in excess of 15%.
(c)
Mature permanent vegetation considered by the
Board of Supervisors to be a natural amenity worthy of preservation.
(d)
Other natural features of irreplaceable value,
subject to the concurrence of the Board of Supervisors.
(e)
Historic sites as identified by the Montgomery
County Resource Protection Plan, or other sites supported by appropriate
documentation or endorsement of local historic societies.
(f)
Land suitable for active or passive recreational
use, subject to the concurrence of the Board of Supervisors.
(4)
The tract shall be served by public sewer and water
facilities. If the tract is in a designated sewer growth area of Whitpain
Township's Sewage Facilities Plan, then conditional zoning and subdivision
approval may be granted. However, no building permits will be issued
until there is adequate capacity in sewer and water transmission lines,
adequate capacity in the sewage treatment plant and adequate water
supplies.
B.
Development regulations.
(1)
Density. The total number of dwelling units permitted
shall be determined in the following manner:

Deed-restricted open space created by lot size reduction shall have
the following minimal requirements:
