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-2 Low-Density 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.
Land in the R-2 Low-Density Residential District
may be used for the following purposes:
A.
Residential development and related open land. Single-family detached dwellings shall be permitted at a maximum density of one dwelling unit per one gross acre. Maximum tract density may be reduced by the environmental adjustment factors in § 170-41 of this chapter, as determined by the formula in § 170-41B(1) of this chapter.
(2)
Neighborhood lotting. Tracts of 10 acres or more may be planned for single-family detached dwellings in compliance with the density and dimensional regulations for neighborhood lotting in § 170-50 and the development regulations for neighborhood lotting in § 170-53, with at least 55% of the tract preserved as common open land. Neighborhood lotting is permitted when approved as a conditional use by the Board of Supervisors, in compliance with § 170-31 of this chapter.
B.
Other principal uses.
(1)
Agricultural activities of the following types:
(a)
The cultivation, harvesting, and sale of crops
and related farm products raised on the property.
(b)
The raising and sale of livestock or fowl, along
with associated pasture and grazing land. The sale of livestock or
fowl shall be permitted only if raised on the property.
(c)
Orchards, nurseries, greenhouses, and related
horticultural uses.
(2)
Open space uses, primarily passive in nature, including
wildlife sanctuary, forest preserve, nature center, and similar uses.
(3)
Game farm, fish hatchery, hunting or fishing preserve;
or similar uses designed for the protection or propagation of wildlife.
(4)
Parks and recreation areas in compliance with the standards and criteria of Article XIII, Institutional and Recreational Overlay District, when approved by the Board of Supervisors.
(5)
Institutions, by conditional use and in compliance with the standards and criteria of Article XIII, Institutional and Recreational Overlay District, when approved by the Board of Supervisors.
(6)
Government uses, public utility facility.

All developments under the neighborhood lotting option shall comply with all the requirements of § 170-46 of the R-1 District (including: inventory, analysis and optional and required sketch plans; neighborhood design standards; neighborhood setbacks; neighborhood open space standards; estate lot standards; open land standards; ownership and maintenance of common facilities and open land; and phasing of development), except that neighborhood lotting in the R-2 District shall have a minimum of 55% of the gross tract acreage as common open land.

(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 170-53B 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.
