The following is an expansion of the statement of community development objectives contained in §
265-2A of this chapter. The intent of this article is to establish standards and criteria which permit Cluster Development of lands in the R-1 and R-1A Agriculture-Residential Districts and the R-2 Residential District. In addition, the open space regulations of this article also govern the preservation and use of common open space in the R-3 and R-4 Residential Districts, Articles
VI and
VII of this chapter. Furthermore, it is the intent of this article to:
A. Preserve open land, including those areas containing unique and sensitive
natural features such as woodlands, steep slopes, streams, floodplains,
and wetlands, by setting them aside from development.
B. Reduce erosion and sedimentation by the retention of existing vegetation,
and the minimization of development on steep slopes.
C. Preserve scenic views and elements of the Township's rural character,
and to minimize perceived density, by minimizing views of new development
from existing roads.
D. Provide greater design flexibility and efficiency in the siting of
services and infrastructure, by reducing the road length, utility
runs, and the amount of paving required for residential development.
E. Create compact neighborhoods with direct visual access to open land,
with amenities in the form of neighborhood open space, and with a
strong neighborhood identity.
F. Implement the goals of the Douglass Township Open Space Plan and
the Pottstown Metropolitan Regional Comprehensive Plan.
G. To provide for the preservation and maintenance of open land within
Douglass Township to achieve the above-mentioned goals and for active
or passive recreational use by residents.
[Amended 11-3-2014 by Ord. No. 2014-04]
Lots proposed for residential development within the R-1 and
R-1A Agriculture-Residential Districts or the R-2 Residential District
which meet the following criteria must be submitted as a Residential
Cluster Development subject to the provisions of this article. A sketch
plan demonstrating compliance with all applicable zoning regulations
is required.
A. Tract location. When the land is located in the R-1, R-1A, or R-2
Districts;
B. Tract size. When the gross area of the tract is equal to or greater
than 20 acres at the time of the passage of this section amendment;
C. Proposed use. When the proposed use of a tract is for the development
of single-family detached homes; and
D. Public sewer proximity. When any portion of the tract is within 1/3
of a mile from the nearest existing sewer line or a proposed sewer
line as illustrated in the Township's Act 537 Plan.
[Amended 10-3-2011 by Ord. No. 2011-03-01]
Any proposed development on a tract that conforms to the RCD Overlay applicability requirements as stated in §
265-164 may be developed under the permitted uses of the underlying zoning district with the exception of a single-family detached housing residential use. A residential development within the RCD Overlay must be proposed as a residential cluster development meeting the following use requirements:
A. Single-family detached housing units subject to the provisions in §
265-168, Density, dimensional, and design standards.
B. Common open space as defined in §
265-169, Open space standards, comprising the minimums established below. Any tract located in the R-1 District that is within the Douglass Township Act 537 public sewer service area, and has a minimum gross area of 100 acres, may use the open space minimum for R-1A.
(1)
60% of the gross lot acreage in the R-1 District.
(2)
45% of the gross lot acreage in the R-1A District.
(3)
15% of the gross lot acreage in the R-2 District.
C. Accessory uses on the same lot with and customarily incidental to
any permitted use.
D. Estate lot. The number of estate lots permitted is limited to one
per subdivision.
As a conditional use, country residences may be allowed within the portion of the RCD that lies on top of the R-1 and R-1A Agriculture-Residential Districts, pursuant to the dimensional standards in §
265-168B(4). In order to develop country residences, the applicant must demonstrate to the Township's satisfaction that all the following conditions are met, where applicable:
A. It is infeasible to develop the tract in question for cluster development
under the Residential Cluster District due to factors such as the
size or shape of the tract or the location of natural features.
B. The proposed development will not have a disruptive effect on the
existing topography, floodplains, wetlands, mature woodlands or other
natural features on the site.
C. The proposed development shall be consistent with good design principles
and land development practices. Specifically, it shall be designed
to minimize views of dwellings from exterior roads, and to avoid "stripping
out" of lots along those roads.
D. The tract in question can be developed in a manner consistent with
community goals as expressed in the Douglass Township Open Space Plan.
Prior to submittal of preliminary plans or sketch plans showing
the location of proposed lots or roads, the applicant may request
that the Township provide a preservation site plan and list of open
space goals pursuant to the following requirements:
A. The applicant will prepare a map(s) on a sheet(s) of at least 24-inch
by 36-inch, of a scale no greater than one inch equals 100 feet indicating
the general location of salient natural and built features. These
features should include the following where applicable: 100-year floodplains,
wetland areas or hydric soils, steep slopes, ponds and streams, riparian
areas, woodlands, significant specimen trees, existing structures,
scenic views into and from the subject tract, topography, hedgerows,
abutting trails, preserved open space historic sites.
B. After submittal of the site inventory and analysis the Township will
respond to the applicant with a preservation site plan accompanied
by a list of open space goals. The plan shall show the general location
of open space, and the key resources that should be preserved.

At least 30% of all lots (rounded up to the nearest whole number)
in the development must border central open space with the homes facing
the central open space, and all dwelling units shall be located within
800 feet of some type of central open space. For developments where
more than 60% of the gross area of the tract is preserved as open
space and the open space includes improvements, such as a trail or
recreational facilities, the percent of lots required to border the
central open space may be reduced by up to 5%.
D. Public trail option.
(1)
Residential cluster developments may include a publicly accessible trail, paved or unpaved, as a substitution for the required recreational facilities specified in §
265-37 at the discretion of the Township's Board of Supervisors.

Any future cluster development shall be consistent with the
approved sketch plan and development agreement.
In accordance with any existing development containing a Homeowners'
association, residents of such Douglass Township developments so established
or which shall be established in the future shall not be permitted
to park, store, load, prep or maintain any recreational vehicles (RV)
as so defined under this chapter within the development or on a roadway
of the development for a period greater than 72 consecutive hours
or for more than three days within any ten-day period. The ten-day
period shall be counted from the first day of parking during the seventy-two-hour
period and for nine days thereafter.
