In expansion of the legislative intent contained in Article
I, §
350-4, of this chapter, and the community development objectives contained in Article
I, §
350-5, of this chapter, it hereby is declared to be the intent of this article:
A. To preserve open land, including those areas with
unique and sensitive natural features such as steep slopes, floodplains
and wetlands by restricting development therein.
B. To preserve scenic views and elements of the Township
rural character and to minimize perceived density by minimizing views
of new development from existing roads.
C. To provide design flexibility in the siting of homes
and infrastructure.
D. To implement the goals of the Upper Pottsgrove Township
Comprehensive Plan and Parks, Recreation and Open Space Plan.
E. To reduce erosion and sedimentation by the retention
of existing vegetation and minimization of development on steep slopes.
F. To encourage the preservation and improvement of habitat
for various forms of wildlife.
G. To provide for preservation and maintenance of open
land within the Township to achieve the above goals and for active
or passive recreational use by residents.

choices to accommodate a variety of age and income groups and residential
preferences to maintain a diverse Township population.
[Amended 9-27-1999 by Ord. No. 300; 7-10-2000
by Ord. No. 307; 9-8-2003 by Ord. No. 353; 3-28-2005 by Ord. No. 379; 4-18-2011 by Ord. No. 446; 5-20-2019 by Ord. No. 504]
In an R-1 Residential District a building or
structure may be erected, altered or used and a lot or premises may
be used or occupied for any of the following reasons:
A. Neighborhood
lotting. As a permitted use on lots subdivided from tracts of five
acres or more, when said tracts are contained entirely within the
sewer service area as determined by the Township's Act 537 Plan, existing
as of the date of adoption of this chapter, when done as any neighborhood
lotting as outlined in this article. Any residential development proposed
under neighborhood lotting shall have a minimum of five building lots.
B. Standard
lotting.
(1) As a permitted use on lots subdivided from tracts less than five acres in size or on a lot existing as of the date of adoption of this chapter, when done in compliance with the standards of §§
350-67,
350-70,
350-71, "standard lotting," and §
350-73A of the R-1 District; such lots do not need to comply with any other requirements of the R-1 District.
(2) As permitted on lots in excess of five acres so long as the lots can be created through the minor subdivision process pursuant to §
310-10. Such lots to be created through the minor subdivision process must satisfy all of the following conditions:
(a) Contains four lots or less.
(b) Has not been part of a subdivision submitted within the past three
years.
(c) Presently fronts on a physically improved street that is legally
open to the public.
(d) Will not involve the construction of any new street or road, the
extension of municipal facilities or the creation of any other public
improvements.
(e) Requires a variance(s) for no more than one of the proposed lots
on which new construction will occur or may occur in the future.
(f) Is in general conformance with the Township Comprehensive Plan and
other plans.
(3) As a conditional use on lots subdivided from tracts of five acres or more, existing as of the original date of adopting this chapter when done in compliance with the standards of §§
350-67,
350-70, and
350-71 (standard lotting) and §
350-73A, with all conditional use standards in §
350-74 of this article.
The initial formal application for any subdivision in the R-1 District shall include an inventory and analysis of the site as specified in Article
III, §
310-7, of Chapter
310, Subdivision and Land Development. These site elements shall be inventoried and mapped in sufficient detail to allow evaluation of the plan relative to the intent of this district. The Board of Commissioners may reduce the elements to be shown on the site inventory and analysis if warranted by site conditions and the limited size of the tract.
The following standards apply to all residential
development proposed under § 350-66A(1), Neighborhood lotting,
herein:
A. All lots shall be grouped into neighborhoods which shall contain no more than 25 lots, which shall be surrounded by open land, subject to the provisions of Subsection
E. When a development has more than one neighborhood, each shall contain no fewer than five and no more than 25 lots surrounded by open land.
B. The maximum number of lots in a neighborhood may be
increased and neighborhoods may be assembled into larger groupings
with the recommendation of the Planning Commission and approval of
the Board of Commissioners. However, the applicant must demonstrate
that such an alternative plan is more appropriate for the tract in
question and will meet both the general intent and design standards
of this article, rather than being intended solely for economic savings.
C. Neighborhoods are defined by the outer perimeter of
contiguous lotted areas or abutting roads and may contain lots, roads
and neighborhood open space.
D. A plan may contain one or more neighborhoods.
E. The outer boundaries of each neighborhood shall meet the neighborhood setback requirements specified in §
350-71C, herein, except that a maximum of 25% of the lots in a proposed development may extend to the tract boundary or may not directly face open space as required in Subsections
A and
J. This percentage may be increased to a maximum of 35% by conditional use, subject to the provisions specified in §
350-74B.
F. Neighborhoods shall be located on areas of the tract
which are relatively free of sensitive environmental features. Disturbance
of woodlands, hedgerows, mature trees or other significant vegetation
shall be minimized. At a minimum, neighborhoods shall not encroach
upon:
(3) Lands designated a vulnerable resource or conservation
priority in the Township Comprehensive Plan, Open Space and Recreation
Plan or Official Map.
G. Neighborhoods shall be defined and separated by open land in order to provide direct access to open land and privacy to individual yard areas. Neighborhoods may be separated by roads if the road right-of-way is designed as a parkway and meets the setback requirements in §
350-71C.
H. Views of neighborhoods from exterior roads shall be minimized by the use of changes in topography, existing vegetation or additional landscaping beyond the minimum required by Article
IV, §
310-37, of Chapter
310, Subdivision and Land Development.
I. All lots in a neighborhood shall have access from
interior roads, rather than roads exterior to the tract.
J. Lots in a neighborhood shall have the full length of at least one side adjacent to neighborhood open space or other open land (directly or across a road). This open space shall be at least 30 feet in depth; provided, however, up to 25% of the lots may be adjacent to one another or not have direct access to open space. This may be increased to 35% by conditional use, subject to the provisions specified in §
350-74C.
K. Neighborhood open space standards. A neighborhood
with more than 10 residential lots must provide neighborhood open
space which shall:
(1) Be central to the neighborhood it serves. Open land
used to separate neighborhoods may not be counted as neighborhood
open space.
(2) Count as part of the minimum 60% open land requirement.
(3) Be provided at the rate of 1,000 square feet per lot
in the neighborhood it serves.
(4) Provide a minimum of 100 feet of road frontage and
a minimum average width of 30 feet in the neighborhood it serves.
(5) Be permitted to contain stormwater detention basins
or parking areas, but these shall not be included in the required
1,000 square feet per lot.
(6) Take the form of a village green, parkway or cul-de-sac
island in compliance with the following standards:
(a)
Village green. Each village green shall be at
least 10,000 square feet in size, shall be surrounded along at least
1/2 of its perimeter by roads and shall be configured so that a circle
with a radius of 50 feet can fit within the confines of the green.
(b)
Parkway. Each parkway shall have a minimum average
width of 35 feet, shall have a length of at least 150 feet and shall
be surrounded by streets on all sides.
(c)
Cul-de-sac island. Each cul-de-sac island shall
be located in the bulb of a cul-de-sac, shall have a radius of at
least 50 feet and shall be surrounded by streets on all sides.
All residential developments developed under
§ 350-66A(1), Neighborhood lotting, are required to provide
60% of each tract as common open land in compliance with the following
standards:
A. The following uses are permitted in open land areas:
(1) Conservation of open land in its natural state (for
example, woodland, fallow field or managed meadow).
(2) Agricultural uses, including raising of crops or livestock
and farm buildings.
(3) Neighborhood open space as specified in §
350-68.
(4) Passive recreation, including, but not limited to,
trails, picnic areas, community gardens and lawn areas.
(5) Active recreation areas intended to serve one or more neighborhoods, such as playfields, playgrounds and courts, meeting the setback requirements in §
350-71B. Golf courses may be permitted, but shall not include driving ranges or miniature golf.
(6) Water supply and sewage disposal systems for neighborhoods,
the entire development or for individual lots.
(7) Pasture for horses (at a rate not exceeding one horse
per two acres).
(8) Easements for drainage, access, sewer or water lines
or other public purposes.
(9) Stormwater management facilities for the proposed
development, or for a larger area in compliance with a watershed stormwater
management plan (adopted in accord with Act 167, the Storm Water Management
Act of 1978).
(10)
Parking areas of 10 or fewer spaces where necessary
to serve active recreation facilities.
(11)
Aboveground utility and road rights-of-way,
except that their land areas shall not count toward the required minimum
60% total open land requirement.
(12)
A single-estate lot, in compliance with the
following standards:
(a)
A minimum lot size of two acres (see §
350-71B), of which a maximum of one acre may be developed with a single-family detached dwelling and customary accessory uses. A maximum of 50% of the undeveloped portion of the estate lot may be used to meet the 60% open land requirement. This maximum may be increased to 100% by conditional use subject to condition specified in §
350-74C.
(b)
The one acre of the estate lot that may be developed
shall include one single contiguous area of the site not left in its
natural state or used for agricultural purposes, including all dwellings,
accessory buildings and structures and paved areas.
(c)
The developed area of the estate lot shall meet the neighborhood setback standards listed in §
350-71C, with the exception of §
350-71C(1)(d) and
(e).
(d)
Estate lots shall be restricted by a restrictive
covenant against further subdivision.
(e)
Dwellings on estate lots shall be counted toward
the maximum density permitted on a tract.
(f)
Dwellings on estate lots shall be sited according to the same principles as neighborhoods, as per §
350-68, Neighborhood design standards, except that the Board of Commissioners may reduce or eliminate this requirement for existing dwellings.
B. Open land areas shall be located and designed to:
(1) Protect site features identified in the inventory
and analysis as having particular value in compliance with the intent
of this article.
(2) Comply conceptually with the recommendations of the
Township's Parks, Recreation and Open Space Plan and/or Comprehensive
Plan where specified.
(3) Maximize common boundaries with open land on adjacent
tracts, as shown in the Comprehensive Plan or as otherwise required
by the Board of Commissioners in the interest of good planning and
design.
C. Safe and convenient pedestrian and maintenance access
shall be provided to open land areas that are not in estate lots or
used for agricultural purposes.
(1) Each neighborhood shall provide one centrally located
access point per 25 lots, a minimum of 75 feet wide.
(2) Access to open land used for agriculture may be appropriately
restricted for public safety and to prevent interference with agricultural
operations.
(3) Public access to estate lots is not required.
D. The following are prohibited in open land areas:
(1) Use of motor vehicles except within approved driveways and parking areas as permitted in Subsection
A(10) above. Maintenance, law enforcement, emergency and farm vehicles are permitted, as needed.
(2) Cutting of healthy trees, regrading, topsoil removal,
altering, diverting or modifying watercourses or bodies, except in
compliance with a land management plan for the tract in question conforming
to customary and accepted standards of forestry, erosion control and
engineering.
E. Natural features, generally, shall be maintained in
their natural condition, but may be modified to improve their appearance,
functioning or overall condition, as recommended by experts in the
particular area being modified. Permitted modifications may include:
F. Applicants providing open space in conformance with the standards of this section shall be exempt from additional open space or fee in lieu of requirements as specified in §
310-38 of Chapter
310, Subdivision and Land Development.
Because the development of standard one acre lots does not provide design flexibility to preserve existing natural features (as in §
350-68, Neighborhood design standards, and §
350-71C, Neighborhood setbacks), standard lotting shall be based on the application of environmental adjustment factors, as described below:
A. Environmental adjustment factors. Except as may be provided for elsewhere in this article, the following environmental adjustment factors shall be used to determine developable lot area for standard lotting in the R-1 District. Each natural feature in the following figure shall be mapped for each proposed lot and deducted in part or wholly from the total lot area based on the percentages shown on the chart and in compliance with the requirements in Subsection
B, below:

Development under the standards of this article
may be phased and estate lots may be subdivided prior to neighborhood
development in accordance with a unified development plan for the
entire tract and the following requirements:
A. An inventory and analysis of the entire tract shall be completed in accordance with §
350-67.
B. The unified development plan for the tract shall be
approved as a sketch plan and shall be made a part of a binding development
agreement between the applicant and the Township.
C. When estate lots are subdivided prior to neighborhood
development, the following standards shall apply:
(1) If neighborhood development is desired in the future,
the plan must be designed so that sufficient land area is set aside
in a suitable configuration for that purpose.
(2) The maximum density permitted within the neighborhood
development shall be based upon the acreage of the original tract,
minus the dwelling units on the estate lots.
(3) The estate lots shall be restricted from further subdivision
by restrictive covenant when they are created.
(4) Any future neighborhood development shall be consistent
with the approved sketch plan and development agreement.
