In expansion of the declaration of legislative intent and statement of community development objectives found in Article I of this chapter, the primary purpose of the R-1 Rural Residential District is to preserve open land, sensitive natural areas, and rural community character that would be lost under conventional development. In addition, the intent of this district is to permit a reasonable amount of residential development in the form of small, compact neighborhoods of single-family detached homes in an open space setting, located and designed to reduce the perceived intensity of development, preserve natural features and farmland, and provide privacy and neighborhood identity. Specific objectives are as follows:
A.
To provide for a variety of lotting opportunities
consistent with the primary purpose of this district.
B.
To preserve open land, including those areas containing
unique and sensitive natural features such as woodlands, steep slopes,
streams, floodplain and wetlands, by setting them aside from development.
C.
To 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.
To provide greater design flexibility and efficiency
in the siting of services and infrastructure, including the opportunity
to reduce length of roads, utility runs, and the amount of paving
required for residential development.
E.
To create compact neighborhoods with direct visual
access to preserved open land, with amenities in the form of neighborhood
open space, and with a strong neighborhood identity.
F.
To implement the goals of the Township's Comprehensive
Plan and open space/recreation plan.
G.
To reduce erosion and sedimentation by the retention
of existing vegetation, and the minimization of development on steep
slopes.
H.
To create new woodlands through natural succession
and reforestation where appropriate, and to encourage the preservation
and improvement of habitat for various forms of wildlife.
I.
To preserve areas of the Township with productive
agricultural soils for continued or future agricultural use, by preserving
blocks of land large enough to allow for efficient farm operations.
J.
To provide for the preservation and maintenance of
open land within the Township to achieve the above-mentioned goals
and for active or passive recreational use by residents.
K.
To provide standards for preservation of open land
and neighborhood lotting to be used in this district.

of the tract is located within 1/4 mile (1,320 feet) of the future
growth area shown on the CPVRPC Future Land Use Map attached hereto
as Appendix "A" to this chapter; and show that all of the residential
lots proposed for neighborhoods (not estate lots) are situated entirely
within this portion of the tract located within a 1/4 mile (1,320
feet) of this future growth area.
[Added 10-3-2023 by Ord. No. 2023-03]
B.
Neighborhood design standards. The following standards
apply to all residential development proposed under neighborhood lotting:
(1)
All lots shall be grouped into neighborhoods which
shall contain at least five but no more than 25 lots, and are surrounded
by open land. The maximum or minimum number of lots in a neighborhood
may be increased or decreased, and neighborhoods may be assembled
into larger groupings with the approval of the Board of Supervisors.
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 chapter, rather than
being intended solely for economic savings.
(2)
Neighborhoods are defined by the outer perimeter of
contiguous lotted areas or abutting roads, and may contain lots, roads
and neighborhood open space. A plan may contain one or more neighborhoods.
(3)
The outer boundaries of each neighborhood shall meet the neighborhood setback requirements specified in Subsection C of this section. Neighborhoods shall be defined and separated by open land in order to provide direct access to open space 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 Subsection C of this section.
(4)
Neighborhoods shall be located on areas of the tract
which are relatively free of sensitive environmental features. At
a minimum, no residential lot of any neighborhood shall encroach upon:

lots from exterior roads shall be minimized by the use of changes
in topography, existing vegetation or additional landscaping.
(9)
All lots in a neighborhood shall take access from
interior roads, rather than roads exterior to the tract.
C.
Neighborhood setbacks. The outer boundaries of all
neighborhoods shall meet the following setbacks. The boundary is defined
as the outer edge of lots abutting open land (not neighborhood open
space), or of roads adjacent to the fronts of those lots.
(1)
From external road ultimate rights-of-way as defined
by the Township: 200 feet.
(2)
From all other tract boundaries: 100 feet.
(3)
From cropland or pasture land: 100 feet.
(4)
From buildings or barnyards housing livestock: 300
feet.

From wetlands, floodplains or watercourses: 25 feet
(this applies to residential lots within neighborhoods, and not to
neighborhood open space).
(7)
From active recreation areas such as courts or playing
fields (not including tot lots): 150 feet.
(8)
All setback areas along external roads including areas on estate lots shall be landscaped according to the standards of Chapter 145, Subdivision and Land Development, in order to preserve scenic views and integrate the neighborhood into the surrounding landscape. Suggested methods compatible with rural character include deciduous reforestation, hedgerows, and/or naturalistic plantings and land forms.
(9)
Setback standards may be reduced by the Board of Supervisors
under the following circumstances:
(a)
Setbacks from external roads may be reduced
to a minimum of 100 feet if the applicant can demonstrate to the satisfaction
of the Board of Supervisors that existing vegetation and/or topography
form an effective visual buffer along these roads, or where natural
features seriously constrain strict compliance with the two-hundred-foot
requirement and additional landscaped buffering will be provided to
reduce the visual impacts, acceptable to the Board of Supervisors.
(b)
All other setbacks may be reduced to half of the requirement specified above if the applicant can demonstrate to the satisfaction of the Board of Supervisors that reduced setbacks improve the plan's compliance with the neighborhood design standards in Subsection B of this section and the intent of this chapter.
D.

(b)
A mix of estate lots and neighborhood lots,
with required open land.
(c)
One or more estate lots and/or neighborhoods,
with the remaining land functioning as a large residual parcel, such
as may be retained as farmland, although the ultimate development
plan may show additional lotting of the residual parcel.
(d)
Other combinations that may be approved by the
Board of Supervisors, upon recommendation of the Township Planning
Commission.
(4)
Every lot proposed in the ultimate development plan
shall be subject to the overall legal agreements regarding all the

easements shall be required, as appropriate.
(3)
All sewage disposal shall conform to the Townships
Official Sewage Facilities Plan (Act 537), as amended, and may include
the following alternatives:
(4)
All lots, existing or proposed, not located within the areas proposed
for public sewer connection pursuant to the Township's Sewage
Facilities Plan, must employ an on-lot sewage disposal system ("OLDS")
for sewage disposal. An OLDS proposal for such a lot shall utilize
the highest priority method of sewage disposal set forth in the following
Table 170-47B that can be technically and administratively implemented
on the lot. If disposal cannot be provided by a higher-ranked method
than proposed, the applicant must submit a written explanation of
the reasons why the subject lot is not suitable for these higher-ranked
methods, along with the appropriate supporting data. A change in the
number or type of dwelling units, businesses, and/or establishments
that could be served by a certain method of on-lot disposal upon the
lot shall not constitute a valid reason why a higher ranked method
is not utilized in favor of a lower priority method. An applicant
must show that the higher ranked methods of on-lot disposal will not
function upon the lot, are inconsistent with other applicable Township
Code provisions, will result in increased disturbance of protected
natural resources, and/or are not technically/administratively feasible
before proposing to employ a lower-ranked method. The Board will determine,
at its sole discretion, whether the use of a lower ranked method complies
with the requirements of this section. The repair of an existing OLDS
that is failing does not have to comply with this section.
