The purpose of these Planned Residential Development (PRD) regulations is to permit residential development which is more creative and imaginative than is generally possible under conventional zoning district controls and subdivision requirements. Further, these regulations are intended to promote more economical and efficient use of the land while providing a compatible blend of housing types, amenities and community facilities of high quality, oriented to the specific development site and providing public trails, and preserving the natural scenic qualities of open space.
The provisions of this article for approval of a planned residential development shall be a modification to and in lieu of procedures and criteria for approvals otherwise required in this chapter and the Municipal Subdivision and Land Development Ordinance.[1] Failure to comply with the provisions of this article with respect to a recorded development plan shall be deemed to constitute a violation of this chapter.

(2) 
Public trails in required common open space. The developer shall comply with the Municipality of Murrysville 2000 Recreation, Park and Open Space Plan and subsequent Policy for the Acquiring and Constructing of Public Trails within Residential Developments. Compliance with the plan, dedication of easements or rights-of-way as required by the standards of Ordinance No. 631-03 and amendments, and providing the required common open space shall be deemed as satisfaction of the mandatory dedication of land for parks and recreation requirement of Ordinance No. 631-03 and amendments.[1]
[1]
Editor's Note: The provisions of Ord. No. 631-03, an amendment to the Subdivision and Land Development Ordinance pertaining to the dedication of land for parks and recreation, have been incorporated into Ch. 201, Subdivision and Land Development.
E. 
Maximum dwelling unit density.
(1) 
Regardless of whether a planned residential development is comprised of a mix of dwelling unit types or a single type of dwelling unit, the maximum dwelling unit density shall be calculated as "density, net residential" and shall be the same as that of the base zoning district. Dwelling unit density shall be calculated as follows:
Number of Units Permitted = [(Gross Acreage — Acreage of Environmentally Sensitive Areas) * .8)] / Minimum Acres per Dwelling Unit permitted in the underlying residential district)
The aforementioned "environmentally sensitive areas" shall be deemed to include steep slopes, floodplains, and wetlands.
(2) 
Or, the developer may submit, or the Planning Commission or Council may require the developer to submit, a plan showing how the site may be developed under conventional zoning following all current ordinances, including grading, slopes, wetlands, land development, streets, etc.; such plan must also be economically viable. This number of lots achieved in the conventional subdivision could be approved by the Planning Commission and Council as an adjusted maximum density.
F. 
Minimum building setback on the perimeter of the planned residential development site. In the R-3 District, apartments shall be located no closer to the boundary of the planned residential development site than 50 feet. In all zoning districts where planned residential development is authorized, no garden apartment, townhouse, triplex or fourplex shall be located closer to any boundary of the planned residential development site than 50 feet. All other structures shall be located at least 40 feet from the boundary of the planned residential development site. No accessory structure and no off-street parking shall be located in this required perimeter setback area.
G. 
Distance between buildings. Where two or more principal multifamily buildings that are three stories or less in height are proposed on one lot, the minimum distance between the buildings shall be 10 feet. Where two or more principal multifamily buildings that are more than three stories in height are proposed on one lot, the minimum distance between the buildings shall equal the height of the taller building.
H. 
Modifications to otherwise applicable zoning and subdivision regulations
(1) 
The design and construction standards of the Municipal Subdivision and Land Development Ordinance[2] shall apply to all public improvements proposed in a planned residential development unless a waiver or modification is granted by the Council in accordance with the procedure specified in the Municipal Subdivision and Land Development Ordinance.
[2]
Editor's Note: See , Subdivision and Land Development.
(2) 
Except for maximum dwelling unit density and maximum building height, any of the other requirements of the underlying zoning district classification may be modified by the Council in granting tentative approval to a planned residential development, if the Board determines that the requested modification or modifications will contribute to a more beneficial use of the site, will not be contrary to the public interest and are warranted owing to unique physical circumstances or conditions unique to the particular property.
(3) 
All requests for modification shall be in writing and shall accompany and be a part of the application for tentative and final approval. Such written request shall specify the ordinance section from which a modification is requested and shall state the grounds for the request, the unreasonable hardship on which the request is based and the minimum modification necessary to relieve the hardship.
(4) 
Whenever a request for modification is granted or denied, the reasons for such grant or denial shall be stated within the official written communication to the landowner. The grant of a modification request may be subject to reasonable conditions designed to promote the purposes set forth in this article.

(2) 
Of the thirty-percent required open space area, 0.033 acres of ground per dwelling unit shall qualify as "active recreation land" space as described in the "Mandatory Dedication of Land for Parks and Recreation."[1] The applicant may pay the fee in lieu of the active recreation land as calculated by that ordinance upon mutual agreement with the Municipality.
[1]
Editor's Note: See § 201-77 in Ch. 201, Subdivision and Land Development.
B. 
Protection of common open space. Common open space in a planned residential development shall be protected by adequate covenants running with the land or by conveyances or dedications. A planned residential development shall be approved subject to the submission of a legal instrument or instruments setting forth a plan for the permanent preservation, care and maintenance of such common open space, recreational areas and other facilities owned in common. No such instrument shall be acceptable until approved by the Council as to legal form and effect. In cases where the Municipality will not be accepting dedications of streets, recreation areas or common open spaces, the developer shall provide for an organization or trust for ownership and maintenance of the common open space and common facilities.
C. 
Common open space maintenance. In the event that the organization established to own and maintain the common open space, or any successor thereto, shall at any time after establishment of the final development plan fail to maintain the common open space, including all streets, driveways and recreational facilities, in reasonable order and condition in accordance with the development plan granted final approval, the Municipality may take remedial action to cause the common open space and common facilities to be properly maintained, as provided for in Section 705(f) of the Pennsylvania Municipalities Planning Code.[2]
