[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.
