This Part regulates and controls Planned Development — both Planned Residential Development and Planned Mixed-use Development — activities within the Municipality of Mt. Lebanon. When a Developer proposes flexible and innovative design techniques, the Planned Development District process offers an opportunity for creative solutions and development. This Part provides uniform development standards and application processes for the Planned Development District applications. The Traditional Neighborhood Development concepts are desirable for all Planned Development Districts.
The Planned Residential Development regulations set forth in this Part 5 are made in accordance with the Comprehensive Plan and are intended to achieve the following goals:
502.1. 
Preserve natural topography, trees, geologic features and prevent soil erosion.
502.2. 
Provide more usable open space including Recreation Space.
502.3. 
Promote an efficient Use of land resulting in smaller networks of utilities and Streets.
502.4. 
Provide a maximum choice in the types of environment, occupancy tenure, types of housing, Lot sizes and common facilities.
502.5. 
Provide a method for redeveloping older residential areas.
503.1. 
Administration. The Zoning Officer is hereby appointed the Administrator.
503.2.

503.2.6.2. 
Grant of Final Approval.
503.2.6.2.1. 
In the event the Municipality does not propose to accept the Streets and sewers which have been dedicated by the Developer, the Municipality may authorize the Developer, without in any way precluding the Municipality from accepting the dedication at some future time, to install said Streets, sewers, and other improvements in accordance with the following procedures.
503.2.6.2.1.1. 
At the time the Final Plat and final Development Plan are submitted, the Developer shall furnish a surety bond to the Municipality in an amount sufficient to cover 110%, as determined by the Commission, of the estimated costs of installing the necessary grading, paving and other Street improvements, including, where specified by the Commission, curbs, sidewalks, Street lights, shade trees, fire hydrants, water mains, sanitary sewers, and storm sewers in accordance with the standards and specifications of the Municipality.

503.2.6.2.3. 
In the event the application for final approval has been filed, together with all drawings, specifications and other documents in support thereof as required by applicable provisions of the Mt. Lebanon Code and the official written communication of the tentative approval, the Commission shall, within 30 days of such filing, grant final approval to said Development Plan.
503.2.6.2.4. 
The Developer shall also obtain a building permit, Street opening permit, Parking Facilities permit, or other applicable permits as required by the Mt. Lebanon Code or by State or federal laws.
503.2.6.3. 
Denial of Final Approval. In the event the development plan as submitted contains variations from the development plan given tentative approval, the approving body may refuse to grant final approval and shall, within 45 days from the date of the regular meeting of the governing body or the planning agency, whichever first reviews the application, next following the date the application is filed, so advise the landowner in writing of said refusal, setting forth in said notice the reasons why one or more of said variations are not in the public interest. Provided, however, that should the next regular meeting occur more than 30 days following the filing of the application, the forty-five-day period shall be measured from the 30th day following the day the application has been filed, In the event of such refusal, the landowner may either:
503.2.6.3.1. 
Refile his application for final approval without the variations objected: or
503.2.6.3.2. 
File a written request with the approving body that it hold a public hearing on his application for final approval.
If the landowner wishes to take either such alternate action, he may do so at any time within which he shall be entitled to apply for final approval, or within 30 additional days if the time for applying for final approval shall have already passed at the time when the landowner was advised that the development plan was not in substantial compliance. In the event the landowner shall fail to take either of these alternate actions within said time, he shall be deemed to have abandoned the development plan. Any such public hearing shall be held pursuant to public notice within 30 days after request for the hearing is made by the landowner, and the hearing shall be conducted in the manner described in this article for public hearings on applications for tentative approval. Within 30 days after the conclusion of the hearing, the approving body shall by official written communication either grant final approval to the development plan or deny final approval. The grant or denial of final approval of the development plan shall, in cases arising under this section, be in the form and contain the findings required for an application for tentative approval set forth in this article. Failure of the governing body or agency to render a decision on an application for final approval and communicate it to the applicant within the time and in the manner required by this section shall be deemed an approval of the application for final approval, as presented, unless the applicant has agreed in writing to an extension of time or change in the prescribed manner of presentation of communication of the decision, in which case, failure to meet the extended time or change in manner or presentation of communication shall have like effect.
503.2.6.4. 
A Development Plan, or any part thereof, which has been given final approval shall be so certified without delay by the approving body and shall be filed of record forthwith in the office of the recorder of deeds before any development shall take place in accordance therewith. Upon the filing of record of the development plan the zoning and subdivision regulations otherwise applicable to the land included in such plan shall cease to apply thereto. Pending completion, in accordance with of said planned residential development or of that part thereof, as the case may be, that has been finally approved, no modification of the provisions of said development plan, or part thereof; as finally approved, shall be made except with the consent of the landowner. Upon approval of a final plat, the developer shall record the plat in the office of the recorder of deeds. Forthwith upon the recording of the final Development Plan, the Commission, by ordinance, shall amend the Zoning District Map to designate the area covered by the recorded Development Plan as a Planned Residential District.
503.2.6.4.1. 
Following such action by the Commission, the zoning and subdivision regulations otherwise applicable to the land included in such Development Plan shall cease to apply thereto.
503.2.6.5. 
Phasing of Development Plan. In the event the Planned Residential Development is to be phased over a period of more than one year, the schedule of the proposed times within which applications for final approval of all sections as required by §503.2.4.14 of this chapter, shall be updated annually on the anniversary of its approval until the Planned Residential Development is completed and accepted in its totality. The construction and provision of all of the Common Open Spaces and public facilities which are shown on the final Development Plan should proceed at the same rate as the construction of development. At least once every six months following approval of the final Development Plan, the Administrator shall review all building permits issued for the Planned Residential Development and examine the construction which has taken place on the site. If he shall find that the rate of construction of Dwelling Units is greater than the rate at which Common Open Spaces and Common Service Facilities are being constructed and provided, he shall notify the Commission. In this latter event, the Commission may direct the Developer to accelerate the construction and provision of Common Open Space and Common Service Facilities; and if the Developer shall fail to accelerate as directed, the Commission may in addition to, or in lieu of, any other remedy afforded hereunder or otherwise provided by law, direct the Developer to cease all work in the Planned Residential Development.
503.2.6.6. 
Change in Development Plan. In the event a Development Plan or section thereof has been given final approval, and the Developer decides to abandon said Development Plan or section or shall so notify the Commission in writing of his intention to abandon said Development Plan, no development or further development shall take place on the property covered by the Development Plan until the said property is re-subdivided and reclassified by enactment of an amendment to the Zoning District Map.
