[Added 6-14-2021 by Ord. No. 1095]
A. 
Purpose. It is the purpose of this article to establish regulations and controls for the use of land and structures, areas of lots, bulk of buildings, amount and kind of open space, the provision of off-street parking and other similar accessory regulations in a PRD in accordance with guidelines set forth in the MPC 53 P.S. § 10701 et seq., as amended. The purpose of these PRD regulations is to provide for residential development as a single unit and permit more flexibility than is generally possible under conventional zoning controls. Further, the PRD is intended to:
(1) 
Provide for a more varied, innovative and efficient development pattern consistent with traditional patterns and scale of development, a mix of uses, and designs that occurred prior to newer suburban development patterns.
(2) 
Preserve the existing topography and wooded slopes by encouraging clustered development and limiting hillside development beyond a reasonable gradient.
(3) 
Promote a mix of diverse but compatible types of neighborhood development.
(4) 
Encourage a blend of housing at a moderate density to serve various age groups and types of housing.
(5) 
Provide for safe and convenient pedestrian, bicycle, and vehicle circulation.
(6) 
Provide walkable development patterns and shift the focus from motor vehicles to pedestrians and bicycles.
(7) 
Encourage persons to work, shop and recreate in and around the neighborhood in which they live.
(8) 
Encourage the creation of a sense of place and a community spirit that promotes social interaction.
(9) 
Conserve open space and encourage a more efficient use of land, resulting in small networks of utilities and streets and lower housing and infrastructure maintenance costs.

All plant material shall be planted in a manner so as to not cause damage to utility lines (above and below ground) and public roadways.
(f) 
Existing plant material which complies with the standards of intent of this chapter and the provisions of this section may be credited toward meeting the landscape requirements.

In the event that the organization established to own and maintain common open space, or any successor organization, shall at any time after establishment of the PRD fail to maintain the common open space in reasonable order and condition in accordance with the development plan, the Township may serve written notice upon such organization or upon the residents of the PRD setting forth the manner in which the organization has failed to maintain the common open space in reasonable condition.

At such hearing, the Township may modify the terms of the original notice as to the deficiencies and may give an extension of time within which they shall be corrected.
(2) 
If the deficiencies set forth in the original notice or in the modifications thereof shall not be corrected within said 30 days or any extension thereof, the Township, in order to preserve the taxable values of the properties within the PRD and to prevent the common open space from becoming a public nuisance, may enter upon said common open space and maintain the same for a period of one year. Said maintenance by the Township shall not constitute a taking of said common open space nor vest in the public any rights to use the same.
(3) 
Before the expiration of said year, the Township shall, upon its initiative or upon the request from the organization therefore responsible for the maintenance of the common open space, call a public hearing upon notice to such organization or to the residents of the PRD to be held by the Board of Commissioners or its designated agency. At which hearing such organization or the residents of the PRD shall show cause why such maintenance by the Township shall not, at the option of the Township, continue for a succeeding year. If the Township or its designated agency shall determine that such organization is not ready and able to maintain said common open space in a reasonable condition, then the Township may, in its discretion, continue to maintain said common open space during the next succeeding year and, subject to a similar hearing and determination, in each year thereafter.
(4) 
The decision of the Board of Commissioners or its designated agency shall be subject to appeal to court in the same manner and within the same time limitation as is provided for by zoning appeals by this chapter.
