[Added 2-17-2011 by Ord. No. 2011-02]
This article is adopted to implement the purposes and intent of planned residential development as defined and authorized by the Pennsylvania Municipalities Planning Code ("MPC") and to establish qualifications, procedures and standards for such development. The Township, acknowledging that the technology of land development and the demand for housing are undergoing substantial and rapid changes, and recognizing the applicability of the objectives set forth in Article VII of the MPC, adopts this article for the purposes of:
A. 
Providing increased flexibility in the laws governing the development of those areas in the Township which are now substantially open land in close proximity to existing expressway interchanges and major arterial highways and encouraging such development in directions that will recognize both the changes in design and technology in the building industry and the demands in the housing market;
B. 
Insuring that the uniform regulations appropriate to previously developed residential neighborhoods do not operate to discourage efficient and imaginative development of said substantially open areas consistent with the reasonable enjoyment of neighboring properties;
C. 
Encouraging the more efficient use of land;
D. 
Extending opportunities for housing;
E. 
Allowing for compact, integrated, and sustainable development;
F. 
Encouraging the efficient allocation and maintenance by private initiative of common open space ancillary to new residential areas;
G. 
Minimizing traffic congestion; and
H. 
Fostering a sense of place and community.
The Township hereby elects to adopt the provisions of and exercise the powers granted by Article VII of the MPC. In support thereof, the Board makes the following findings:
A. 
Planned residential development is a way of designing residential neighborhoods which can provide a better environment for the people who live there. Its provisions encourage more productive use of open space, the preservation of salient existing natural features of the landscape, more varied and better design, increased pedestrian and vehicular safety, and greater design and planning flexibility than in conventional subdivisions and land developments.
B. 
The Board finds that it is in the best interest of the Township to take full advantage of modern design, construction, technology and planning methods and thus seeks to permit planned residential development, under certain conditions meeting certain design standards of the Township. The objectives to be accomplished by this article (the "PRD objectives") shall include, but are not limited to, the following:
(1) 
To encourage innovative and flexible development plans that will contribute to the quality of life in the community through well-planned land uses and amenities.
(2) 
To provide an optional approach to community development with provisions to permit more efficient use of land on other than a lot-by-lot basis and to recognize changes in design and technology in the building industry, new demands in the housing market, and the continuing evolution of community form.
(3) 
To encourage the efficient allocation and maintenance of common open space ancillary to new residential areas.
(4) 
To provide for the future housing needs of the Township while minimizing traffic impact by encouraging higher intensity residential development on substantially open land in proximity to existing expressway interchanges and adjacent to major arterial highways.
(5) 
To encourage innovations in residential development so that the growing demand for housing and other development may be met by greater variety in type, density, design and layout of dwellings and other buildings and structures and by the conservation and more efficient use of open space ancillary to said dwellings and uses.
(6) 
To assure that the flexibility of regulations herein is carried out pursuant to sound, expeditious and fair administrative standards and procedures.
For the purpose of this article, certain terms, phrases and words are defined as follows:
