[Ord. 94, 6/8/1988; as added by Ord. 111, 11/8/1989, § 706A;
as amended by Ord. 153, 5/3/1994, § 1; and by Ord. 181,
5/16/2000, § I.1]
1.
The RD-C, Residential Development-Conservation District is designed
to provide a variety of housing types, flexibility of design, conservation
of agricultural lands and open space, and preservation of historic
areas. The RD-C District provides densities lower than the RD District
and serves as a transitional zone between RD Districts and conventional
single-family districts in areas proximate to the Borough of New Hope
and accessible from Route 202, the principal highway through the Township.
2.
Specifically, it is the intent and purpose of this section to create
a zoning district which would permit the planning of large land areas
in one or more designated sites and in proper locations, so as to:
A.
Conserve Agricultural Lands and Open Space. Encourage the conservation
of existing farm lands and prime agricultural soils especially where
such lands have the ability to be preserved in their entirety or as
large tracts both on the parcel being developed and on adjacent parcels
by the use of conservation easements and deed restrictions.
B.
Protect Natural Environmental Features. Preserve and protect significant
environmental and natural landscape features especially stream valleys
and associated floodplains and wetlands, lakes and ponds, significant
hedgerows, rare vegetation or habitats of endangered wildlife, viewsheds,
and significant scenic routes.
C.
Preserve Historic Districts. Enhance the opportunity to preserve
historic districts from significant development and control any new
structures so that historic development patterns are respected and
preserved.
D.
Provide for a Variety of Housing Types. Provide the opportunity for
the creation of a wider variety of housing types in the Township,
ranging from single-family detached to age-qualified detached dwelling
units to single-family attached units (townhouses).
E.
Promote the Creative Use of large Tracts. Encourage the creative
use of large tracts of residential land in excess of 100 contiguous
acres which are located on Route 202 so as to promote the establishment
of a more desirable living environment than would be possible through
their subdivision and in accordance with the conventional standards
established elsewhere.
F.
Permit Flexibility of Design and Development. Permit flexibility
of design and development in such a way as to promote superior land
planning design, greater economy, efficiency and convenience in the
arrangement of land uses and their supporting infrastructure, to preserve
open space, and to protect floodplains and other natural features.
G.
Allow Well Planned Services and Utilities. Encourage orderly and
well-planned development of a scale and location that will make it
feasible to construct a comprehensive package of supporting utilities,
services and facilities, active and passive recreation facilities,
a stormwater control and retention system, and other facilities so
as to achieve developments which are environmentally, physically,
visually and economically superior.
H.
Allow Safe Traffic Circulation. Encourage orderly development of
sites with substantial frontage on federally designated highways so
as to provide safe, efficient access and traffic circulation.
I.
Recognize Master Plan Objectives. Promote a development pattern in
harmony with the objectives of the Township's Master Plan.

each lot contains less than one dwelling unit per 10 acres, shall
be permanently designed with a restriction against further subdivision
and development so that the lot(s) remains as open space by conservation
easements and/or deed restrictions in a form acceptable to the Township.
The bonus shall be calculated as follows:
