[Added 2-27-1991 by Ord. No. 91-261]
A. 
Since its inception in the early 1950's, the University Park Airport has continually expanded its size and services. This airport growth creates potential impacts on the surrounding community, including but not limited to the areas of transportation, noise, air and water pollution, safety hazards, need for public infrastructure and emergency services. Future land developments in the Centre Region will place greater demands on this facility and the neighboring largely undeveloped lands.
B. 
In order to meet these demands, land use compatibility between the airport and the neighboring lands is imperative. Prudent planning is essential and must relate to the development goals of the Centre Region municipalities as articulated in the Comprehensive Plan. Development of infrastructure must also be consistent with the impending airport growth to prevent problems and at the same time, protect the environment. Recent studies have identified a significant potential source of groundwater immediately adjacent to the airport. This valuable source of future water supply for the Centre Region must be protected from contamination.
C. 
The Planned Airport District is designed to minimize airport hazards related to development of lands surrounding the University Park Airport and to minimize the potential for contamination of the potential well field located within the district. It is also intended to promote the careful planning and orderly development of lands impacted by the airport consistent with the goals and objectives of Patton Township as described in the Comprehensive Plan. In addition, the district achieves additional purposes that include:
(1) 
Provision of flexibility for land development, while also providing for determination, review and mitigation of potential community and environmental impacts associated with future airport development.
(2) 
Promotion of the health, safety and general welfare of the inhabitants of Patton Township by protecting them from the adverse effects of aircraft noise and preventing an increase in the number of people exposed to airport-related hazards.
(3) 
Prevention of the obstructions and incompatible land uses that affect navigable airspace.
(4) 
Prevention of the development of land uses which tend to concentrate large numbers of people in the airport hazard areas.
(5) 
Encouragement of innovative design in the layout of buildings, structures and open spaces and encouragement of a pattern of development which preserves trees and natural features, and prevents soil erosion.
(6) 
Provision of adequate water supply, sanitary facilities, stormwater management and other utilities and services.
(7) 
Encouragement of innovative strategies to reduce transportation impacts from proposed development that will improve safety, reduce congestion, provide adequate access and promote the use of transportation demand management strategies.
(8) 
Assurance that, to the maximum extent possible, the community is afforded the opportunity to participate in the development or amendment of the district.
(9) 
Provision of criteria that allows a mix of land uses in a growth area served by public utilities with an emphasis on providing area for light industrial uses.
The area of Patton Township designated on the Zoning Map of the Township as the "Planned Airport District" is hereby established as the "Planned Airport District".
A. 
Uses by right.
(1) 
The specific uses permitted within different portions of the Planned Airport District are listed in Table 1.[1] These uses are a function of the noise levels projected to be generated by aircraft using the airport, the proximity of a given area to the airport runways and flight approach paths and the desire to protect the nearby potential groundwater supply from contamination by activities conducted within the district.
(2) 
Lines delineating residential, mixed use and nonresidential areas within the Planned Airport District are to be depicted on and are to be considered an integral part of the Zoning Map. The location of these lines are generally based on projected decibel levels contained in the report prepared by L. Robert Kimball Associates entitled "Noise Analysis Based on 8,500 Foot Runway and Corresponding Operations at the University Park Airport," dated January 5, 1989. The location of these lines is to be considered a fixed part of the Zoning Map and their location can only be changed by amendment of the Zoning Map.
(3) 
In order to protect the safety of persons on the ground and within aircraft, additional safety measures as established by the Federal Aviation Administration will be made part of this chapter. These safety measures are identified as the runway protection zone, runway approach zone and horizontal clearance zone. The runway and approach areas (based on the Federal Aviation Administration runway protection zone and runway approach zone respectively) are to be depicted on and are to be considered an integral part of the Zoning Map and their location can only be changed by amendment of the Zoning Map. The entire Planned Airport District lies within the horizontal clearance zone.
B. 
The concern for protection of the potential future source of groundwater identified in the airport area is embodied within Table 2,[2] which prohibits certain activities from being conducted in the Planned Airport District that could contaminate the potential water supply. In addition, a buffer of at least 150 feet shall be required from all designated well sites. This buffer shall be measured from the perimeter of the designated site(s). Vegetation and/or a combination of low maintenance trees, shrubs and ground cover plantings shall be provided within the buffer. All buildings, structures, parking or other impervious surfaces shall be prohibited from locating in the buffer yard. The designated well sites shall be identified on the Master Plan.
C. 
Notwithstanding any other provisions of this chapter, no use may be made of land or water within any area established by this chapter in such a manner as to create electrical interference with navigational signals or radio communication between the airport and aircraft, make it difficult for pilots to distinguish between airport and aircraft, make it difficult for pilots to distinguish between airport lights and others, result in glare in the eyes of pilots using the airport, impair visibility in the vicinity of the airport, create bird strike hazards or otherwise in any way endanger or interfere with the landing, takeoff or maneuvering of aircraft intending to use the airport. All uses by right permitted in the Planned Airport District must conform to the regulations established by the Federal Aviation Administration that govern development within the airport horizontal clearance zone, runway approach zone and runway protection zones as defined in this chapter.
All development within the Planned Airport District must be done pursuant to approval of a master plan in accordance with the procedure that follows. The minimum area for which a master plan can be prepared is 20 acres. Master plans for the Planned Airport District shall be reviewed by the Patton Township Planning Commission and the Centre Regional Planning Commission and shall be approved or denied by the Board of Supervisors in accordance with the procedures specified herein. Parcels smaller than 20 acres existing on the date of enactment of this chapter are exempt from the master plan requirement, but must conform to all other requirements of this article.
A. 
Preapplication meeting. A preapplication meeting is recommended but shall not be mandatory nor shall it be regarded as a formal application for development in the Planned Airport District. The purpose of the meeting is to provide for an informational exchange at the municipal staff level or Planning Commission level where the major elements of a proposed master plan can be reviewed and evaluated. The Planning Commission may make recommendations as a result of the preapplication conference. The filing of any report, sketch plan, plat or map prior to or at such meeting shall not constitute submission of a plan or application for Planned Airport District Development nor shall such materials be binding on subsequent submissions by the applicant. Any recommendations made by the Planning Commission shall not be binding upon the applicant or the Planning Commission in its review of the plan after formal application.
B. 
Master plan application and review. Application for Township approval of a Planned Airport District Development shall commence with the official submission of a complete set of plans and all required supplementary data and information to the Township. At any time during the review process, the applicant may amend the originally submitted plan solely for the purpose of correcting minor deficiencies in the original plan to the extent necessary to meet the requirements of this section.

A. 
Area requirements.
(1) 
After enactment of this chapter no property within the Planned Airport District may be subdivided or replotted into parcels less than 20 acres except pursuant to an approved master plan.
(2) 
All master plans within the Planned Airport District must encompass an area of at least 20 acres. No development within the Planned Airport District can occur until a master plan has been approved for the area being developed. The only exception to the requirement for a master plan is for any parcel of less than 20 acres existing on the date of enactment of this chapter.
(3) 
Lot sizes shall be established on subdivision and land development plans.
B. 
Density requirements.
(1) 
Maximum density for areas in which residential uses are permitted.
(a) 
The maximum density for areas in which residential uses are permitted shall not exceed the following:
[1] 
One and twenty-five hundredths dwelling units per acre for the area of the Planned Airport District within 500 feet of the district's northwestern boundary line as defined at the end of Table 1.[1]
[2] 
Two and five-tenths dwelling units per residential use acre for the remaining portion of the Planned Airport District that permits residential uses.
(b) 
As an incentive for larger-scale planning, the maximum densities permitted under Subsection B(1)(a)[1] and [2] can be doubled for master plan areas encompassing 100 or more acres. Acreage within the runway area cannot be credited toward master plan acreage for development occurring outside of the runway area.
(2) 
The maximum density for areas to be used for nonresidential uses shall not exceed a Floor Area Ratio (FAR) of two-tenths (0.2). The acreage to be used in determining the FAR is the nonresidential acreage within the Master Plan not contained within the runway area. As an incentive for larger scale planning, the maximum density for areas to be used for nonresidential uses shall not exceed a FAR of four-tenths (0.4) for master plan areas encompassing 100 or more acres. Acreage within the runway area cannot be credited toward master plan acreage for development occurring outside of the runway area.
(3) 
Within any phase of a master plan, where applicable, no more than 20% of the nonresidential floor area may be devoted to the commercial uses listed in Table 1.[2]
C. 
Allowable use percentages.
(1) 
In the mixed use, nonresidential and approach areas, all development plans must devote at least 50% of their area to general airport area uses and shall devote no more than 20% of their area to the commercial uses listed in Table 1.
(2) 
In the residential area only the uses listed in Table 1 shall be permitted.
(3) 
If development done pursuant to an approved master plan is to be done in phases, the construction within each phase must comply with the use percentages listed in part of this section.
D. 
Maximum lot coverage.
(1) 
Within residential use areas, structures shall not cover more than 25% of the lot area. The maximum impervious coverage in residential use areas shall not exceed 50% of the Master Plan area designated for residential uses.
(2) 
Within nonresidential use areas, the maximum impervious coverage shall not exceed 60% of the Master Plan area designated for nonresidential uses.
E. 
Height requirements.
(1) 
The height of all buildings within the Planned Airport District shall not exceed 50 feet or the maximum height limitations imposed by FAA regulations (Part 77) for horizontal clearance zones, runway approach zones or runway protection zones, whichever is less.
(2) 
The height of all structures within the Planned Airport District shall not exceed 70 feet or the maximum height limitations imposed by FAA regulations (Part 77) for horizontal clearance zones, runway approach zones or runway protection zones, whichever is less.
F. 
Setback requirements.
(1) 
Required setbacks from public rights-of-way abutting Master Plan boundaries shall be 100 feet for structures and 50 feet for parking areas.
(2) 
Required setbacks from Master Plan property boundaries that do not abut public rights-of-way shall be 50 feet for structures and 15 feet for parking areas.
(3) 
No minimum setbacks for interior streets or internal lot lines are established herein. Such setbacks will be established by the Board of Supervisors for each subdivision or land development plan submitted pursuant to an approved Master Plan. This allows the designer flexibility in the placement of structures. However, a proposal using minimal setbacks must clearly establish the sufficiency of the design pattern for which the minimum setbacks are proposed.
G. 
Open space requirements.
(1) 
A minimum of 40% of the gross area of the Planned Airport District plan shall be devoted to open space.
(2) 
The Township Supervisors may accept dedication of part of the open space shown on the plan provided that:
(a) 
The land so dedicated is contiguous.
(b) 
The land is accessible to the public.
(c) 
It is viewable from a public street.
(3) 
No more than 15% of the required open space shall contain stormwater management facilities, except for large, flat stormwater detention ponds with a minimum area of 1.0 acres inside the toe of the interior slopes of the pond. This area must be capable of being used as an outdoor recreation facility. Such an area may be added to the 15% maximum as described above upon review and approval by the Municipal Engineer.
A. 
Environmental design. Development in the Planned Airport District should be based on an environmentally harmonious and aesthetically pleasing design. Consideration should be given to the overall character of the development and its visual effect on adjacent uses as well as the tenants of the development, residents of the Township and Centre Region at large. The following factors should be taken into account in the design and presented on all plans submitted pursuant to an approved master plan.
(1) 
Existing trees should be inventoried and preserved whenever possible. Existing stands of mature healthy trees, hedgerows, waterways, historic sites, scenic points, views and vistas and other community assets and landmarks should be preserved.
(2) 
The development plan should be designed to minimize grading and other changes to the natural terrain. All graded slopes should blend with the surrounding terrain and development.
(3) 
All landscaping shall be in conformance with an overall landscaping plan and unifying concept for the development.
(4) 
Buffer yards. The determination of the buffer yards shall be made through the use of Tables 3, 4 and 5.[1] All uses within each use classification would be considered to have an equal impact on neighboring uses. Impacts resulting from greater intensity uses on adjacent parcels would include: noise, dust, lighting glare, heat, traffic, building bulk and height, storage areas and impervious surface areas. The intensity of adjoining uses must also be determined from the classification system. Once the land use classifications are determined, the appropriate buffer yard can then be applied to the land development.
(a) 
Buffer yards are required, as applicable, on each lot (or lease area) or land development area independent of adjoining uses or adjoining buffers.
(b) 
If a developed use increases in intensity or changes, increases in the buffer yards may be required by the Board of Supervisors.
(c) 
Consideration should be given to utilizing existing vegetation as an element in the application of buffer yards.
(d) 
Buffer yards shall not be used for parking, loading, storage or structures. All except side buffer yards of interior lots may be crossed by access driveways and utility easements, provided that such are not more than 25 feet in width at the point of intersection.
(e) 
Where a required buffer yard is wider than the setback(s) required in the district, the wider dimension will govern.
(f) 
All plantings shall be selected to be compatible with the environmental conditions they will be exposed to. Any plant material that does not survive must be replaced within one year.
