In addition to the zoning districts established in this chapter and delineated on the zoning district map, all areas containing or characterized by the features listed hereunder are established as overlay districts in accordance with Section 605 of the Pennsylvania Municipalities Planning Code.[1]
A. 
FP: Floodplain Areas, § 460-704.
B. 
AH: Airport Hazard Areas, § 460-705.
[1]
Editor's Note: See 53 P.S. § 10605.
The location of each overlay district is delineated on a map depicting that overlay feature. These maps are adopted as a part of the Zoning District Map.
A. 
Accuracy of overlay districts. Overlay districts may not include all land or sites subject to the special features of the overlay district, and not all land within the overlay district may actually contain the special or limited feature.
B. 
Areas not included in overlay districts. It is the intent of this article that the limitations on development which are imposed by the overlay district regulations shall apply to all parcels which include the regulated feature, whether or not the land is shown in the overlay district. It shall be the responsibility of the applicant to establish the presence or absence on the proposed site of all features subject to regulation in this article.
C. 
Interpretation of overlay districts. If the zoning district map or list is questioned, the burden of proof shall be upon the developer, who shall submit information from a qualified professional or other expert acceptable to the Township to demonstrate that the site in question can be used in the manner proposed without violation of this article.
The regulations contained in this article shall apply to the use of parcels and structures in each overlay district. These restrictions shall be in addition to other regulations in this article.
A. 
Limitations of intensity of development. The amount of site area used or occupied by development is restricted as specified by the applicable district regulations and as further restricted by the overlay district regulations of this article.
B. 
Limitations on authorized uses in overlay districts. Uses in overlay districts may be authorized by right, by conditional use, by special exception, or by planned development subject to the applicable district regulations and as further stated in the overlay district.
(1) 
Uses permitted by conditional use. All uses by right in any zoning district which are prohibited because of the regulations of any overlay district may be permitted by conditional use in any overlay district, provided the use complies with the specific regulations of any overlay district, and uses permitted by conditional use may be permitted by conditional use in any overlay district, provided the use complies with the regulations of the particular overlay district.
(2) 
Uses permitted by special exception. All uses by special exception in any zoning district which are prohibited because of the regulation of any overlay district may be permitted by special exception in any overlay district, and uses permitted by special exception may be permitted by special exception in any overlay district, provided the use complies with the regulations of the particular overlay district.
(3) 
Uses permitted by planned residential development. All uses by planned residential development in any zoning district which are prohibited because of the regulations of any overlay district may be permitted by planned residential development in any overlay district, provided the use complies with the specific regulations of any overlay district, and uses permitted by planned residential development may be permitted by planned residential development in any overlay district.
A. 
Intent. The intent of regulating development in floodplain areas is to eliminate loss of life, health hazards and property damage which may be caused by floods; to preserve the capacity of stream channels and adjacent floodplains areas to carry floodwaters; and to encourage the use of flood-prone land for open space uses.
B. 
Identification of floodplain areas. The identified floodplain area shall be those areas of the Township which are subject to the 100-year flood, as identified in the Flood Insurance Study (FIS), or most recent revisions thereof. The identified floodplain area shall consist of the following specific areas.
(1) 
FW (floodway area). The areas identified as floodway in the AE Zone in the FIS. The term shall also include floodway areas which have been identified in other available studios or sources of information for those floodplain areas where no floodway has been identified in the FIS.
(2) 
FF (flood-fringe area). The remaining portions of the 100-year floodplain in those areas identified in the AE Zone in the FIS, where a floodway has been delineated. The basis for the outermost boundary of this area shall be the 100-year flood elevations as shown in the flood profiles contained in the FIS.
(3) 
FA (general floodplain area). The areas identified as Zone A in the FIS for which no 100-year flood elevations have been provided.
(a) 
When available, information from federal, state, and other acceptable sources shall be used to determine the 100-year elevation, as well as a floodway area, if possible.
(b) 
When no other information is available, the Township shall require the applicant to determine the 100-year flood elevation and to delineate a floodway area using hydrologic and hydraulic engineering techniques. Hydrologic and hydraulic analyses shall be undertaken only by professional engineers, or others of demonstrated qualifications, who shall certify that the technical methods used correctly reflect current accepted technical concepts. Studies analyses, computations, etc., shall be submitted in sufficient detail to allow a thorough technical review by the Township.
(c) 
Changes in identification of identified floodplain area. The identified floodplain area may be revised or modified by the Supervisors where studies or information provided by a qualified agency or person documents the need for such revision. However, prior to any such change, approval must be obtained from the Federal Insurance Administration.
(d) 
Boundary disputes. Should a dispute concerning any identified floodplain boundary arise, an initial determination shall be made by the Planning Commission. Any party aggrieved by this decision may appeal to the Zoning Hearing Board. The burden of proof shall be on the appellant.
(4) 
Authorized uses in the Floodplain Overlay District. Any use authorized in any zoning district may be authorized by the appropriate procedure, provided the use is in compliance with this article, except for the following uses which shall be prohibited within any identifiable floodplain area:
(a) 
Mobile buildings, mobile homes, and manufactured homes.
(b) 
Hospitals.
(c) 
Intermediate-care facility, personal-care boarding home, and skilled nursing home.
(d) 
Jails, prisons and detention centers.
(e) 
Mobile home parks and campgrounds having spaces for recreation vehicles.
(f) 
Maintenance of a supply of any amount of Class A or B poison, water-reactive liquid or solid, etiologic agents or radioactive material, as defined by the United States Department of Transportation Hazardous Materials Tariff.
(g) 
Productions, storage or use of any hazardous materials identified by the United States Department of Transportation Hazardous Materials Tariff.
(5) 
The following uses shall be revised with certain quantity limits within an identified floodplain area:
(a) 
Maintenance of a supply of any hazardous materials as defined by the United States Department of Transportation Hazardous Materials Tariff, not including those listed in § 460-704B(4)(f); such supply shall not exceed 550 gallons or other comparable measure.
C. 
Standards for development in Floodplain Area Overlay Districts.
(1) 
General.
(a) 
No encroachment, alteration, or improvement of any kind shall be made to any watercourse until all adjacent municipalities which may be affected by such action have been notified by the Township and until all required permits or approvals have been first obtained from the Pennsylvania Department of Environmental Protection, Bureau of Dams, Waterways and Wetlands. In addition, the Federal Emergency Management Agency and Pennsylvania Department of Community and Economic Development, Bureau of Community Planning, shall be notified by the Township prior to any alteration or relocation of any watercourse.
(b) 
Any new construction, development, uses or activities allowed within any identified floodplain area shall be undertaken in strict compliance with the provisions contained in this article and any other applicable codes, ordinances and regulations. No approval shall be issued until this determination has been made. It shall be the responsibility of the applicant to obtain all such necessary other governmental permits.
(c) 
The Federal Insurance Administrator and Pennsylvania Department of Community and Economic Development, Bureau of Community Planning, shall be notified by the Township prior to any alteration or relocation of any watercourse.
(2) 
Special requirements for FW and FA areas.
(a) 
Within any FW (floodway area), the following provisions apply:
[1] 
Any new construction, development, use, activity, or encroachment that would cause any increase in flood heights shall be prohibited.
[2] 
Any new construction or development which would cause any increase in flood heights shall be prohibited within any floodway area.
(3) 
Placement of buildings and structures. Within any identified floodplain area, all buildings and structures shall be designed, located, and constructed so as to offer the minimum obstruction to the flow and height of floodwater.
(4) 
Storage. Within any identified floodplain area, all materials that are buoyant, flammable, explosive or, in times of flooding, could be injurious to human, animal, or plant life shall be stored at, or above, the regulatory flood elevation and shall be floodproofed to the maximum extent possible.
(5) 
On-site sewage systems. No part of any on-site sewage system shall be located within any identified floodplain area except in strict compliance with all state and local regulations for such systems. If any such systems is permitted, it shall be located so as to avoid impairment to it, or contamination from it, during a flood.
(6) 
Continuance. Structures and uses existing in any identified floodplain area prior to the enactment of this article may continue subject to the following provisions:
(a) 
No expansion or enlargement of an existing structure or use shall be allowed within any identified floodway that would cause any increase in the elevation of the 100-year flood.
(b) 
Any modification, alteration, reconstruction, or improvement of any kind to an existing structure, to an extent or amount of 50% or more of its market value, shall constitute a substantial improvement and shall be undertaken only in full compliance with the provisions of this article.
The purpose of this chapter is to create an Airport District Overlay that considers safety issues around the Washington County Airport, regulates and restricts the heights of constructed structures and objects of natural growth, creates appropriate zones, establishing the boundaries thereof and providing for changes in the restrictions and boundaries of such zones, creates the permitting process for use within said zones and provides for enforcement, assessment of violation penalties, an appeals process, and judicial review.
The Airport District Overlay shall not modify the boundaries of any underlying zoning district. Where identified, the Airport District Overlay shall impose certain requirements on land use and construction in addition to those contained in the underlying zoning district.
The following words and phrases when used in this article shall have the meaning given to them in this section unless the context clearly indicates otherwise.
AIRPORT ELEVATION
The highest point of an airport's usable landing area measured in feet above sea level. The airport elevation of the Washington County Airport is 1,184 feet.
AIRPORT HAZARD
Any structure or object, natural or man-made, or use of land which obstructs the airspace required for flight or aircraft in landing or taking off at an airport or is otherwise hazardous as defined in 14 CFR Part 77 and 74 Pa.C.S.A. § 5102.
AIRPORT HAZARD AREA
Any area of land or water upon which an airport hazard might be established if not prevented as provided for in this chapter and the Act 164 of 1984[1] (Pennsylvania Laws Relating to Aviation).
APPROACH SURFACE (ZONE)
An imaginary surface longitudinally centered on the extended runway center line and extending outward and upward from each end of the primary surface. An approach surface is applied to each end of the runway based on the planned approach. The inner edge of the approach surface is the same width as the primary surface and expands uniformly depending on the planned approach. The approach surface zone, as shown on Figure 1, Surface Areas,[2] is derived from the approach surface.
CONICAL SURFACE (ZONE)
An imaginary surface extending outward and upward from the periphery of the horizontal surface at a slope of 20 feet horizontally to one foot vertically for a horizontal distance of 4,000 feet. The conical surface zone, as shown on Figure 1, Surface Areas,[3] is based on the conical surface.
DEPARTMENT
Pennsylvania Department of Transportation.
FAA
Federal Aviation Administration of the United States Department of Transportation.
HEIGHT
For the purpose of determining the height limits in all zones set forth in this chapter and shown on the Zoning Map, the datum shall be mean sea level elevation unless otherwise specified.
HORIZONTAL SURFACE (ZONE)
An imaginary plane 150 feet above the established airport elevation that is constructed by swinging arcs of various radii from the center of the end of the primary surface and then connecting the adjacent arc by tangent lines. The radius of each arc is based on the planned approach. The horizontal surface zone, as shown on Figure 1, Surface Areas,[4] is derived from the horizontal surface.
LARGER THAN UTILITY RUNWAY
A runway that is constructed for and intended to be used by propeller driven aircraft of greater than 12,500 pounds maximum gross weight and jet-powered aircraft.
NONCONFORMING USE
Any preexisting structure, object of natural growth, or use of land which is inconsistent with the provisions of this chapter or an amendment thereto.

PRIMARY SURFACE (ZONE)
An imaginary surface longitudinally centered on the runway, extending 200 feet beyond the end of paved runways or ending at each end of turf runways. The elevation of any point on the primary surface is the same as the elevation of the nearest point on the runway center line. The primary surface zone, as shown on Figure 1, Surface Areas,[5] is derived from the primary surface.
RUNWAY
A defined area of an airport prepared for landing and takeoff of aircraft along its length.
STRUCTURE
An object, including a mobile object, constructed or installed by man, including but without limitation, buildings, towers, cranes, smokestacks, earth formation and overhead transmission lines.

There are hereby created and established certain zones within the Airport District Overlay ordinance, defined in § 460-705.04 and depicted on Figure 1, Surface Areas,[1] and illustrated on the Washington County Airport Hazard Area Map, hereby adopted as part of this chapter, which include:
A. 
Approach Surface Zone.
B. 
Conical Surface Zone.
C. 
Horizontal Surface Zone.
D. 
Primary Surface Zone.
E. 
Transitional Surface Zone.
[1]
Editor's Note: Said figure is included as an attachment to this chapter.
A. 
As regulated by Act 164 and defined by 14 CFR Part 77.13(a) (as amended or replaced), any person who plans to erect a new structure, to add to an existing structure, or to erect and maintain any object (natural or man-made) in the vicinity of the airport shall first notify the Department's Bureau of Aviation (BOA) by submitting PennDOT Form AV-57 to obtain an obstruction review of the proposal at least 30 days prior to commencement thereof. The Department's BOA response must be included with this permit application for it to be considered complete. If the Department's BOA returns a determination of no penetration of airspace, the permit request should be considered in compliance with the intent of this Overlay ordinance. If the Department's BOA returns a determination of a penetration of airspace, the permit shall be denied and the project sponsor may seek a variance from such regulations as outlined in § 460-705.06.
B. 
No permit is required to make maintenance repairs to or to replace parts of existing structures which do not enlarge or increase the height of an existing structure.
A. 
Any request for a variance shall include documentation in compliance with 14 CFR Part 77 Subpart B (FAA Form 7460-1 as amended or replaced). Determinations of whether to grant a variance will depend on the determinations made by the FAA and the Department's BOA as to the effect of the proposal on the operation of air navigation facilities and the safe, efficient use of navigable airspace. In particular, the request for a variance shall consider which of the following categories the FAA has placed the proposed construction in:
(1) 
No objection. The subject construction is determined to not exceed obstruction standards and marking/lighting is not required to mitigate potential hazard. Under this determination a variance shall be granted.
(2) 
Conditional determination. The proposed construction/alteration is determined to create some level of encroachment into an airport hazard area which can be effectively mitigated. Under this determination, a variance shall be granted contingent upon implementation of mitigating measures as described in § 460-705.09, Obstruction marking and lighting.
(3) 
Objectionable. The proposed construction/alteration is determined to be a hazard and is thus objectionable. A variance shall be denied and the reasons for this determination shall be outlined to the applicant.
B. 
Such requests for variances shall be granted where it is duly found that a literal application or enforcement of the regulations will result in unnecessary hardship and that relief granted will not be contrary to the public interest, will not create a hazard to air navigation, will do substantial justice, and will be in accordance with the intent of this chapter.
Notwithstanding any other provisions of this chapter, no use shall be made of land or water within the Airport District Overlay in such a manner as to create electrical interference with navigational signals or radio communications between the airport and aircraft, make it difficult for pilots to distinguish between airport lights and others, impair visibility in the vicinity of the airport, create bird strike hazards or otherwise endanger or interfere with the landing, takeoff or maneuvering of aircraft utilizing the Washington County Airport.
The regulations prescribed by this chapter shall not be construed to require the removal, lowering, or other change or alteration of any structure or tree not conforming to the regulations as of the effective date of this chapter or otherwise interfere with the continuance of a nonconforming use. No nonconforming use shall be structurally altered or permitted to grow higher, so as to increase the nonconformity, and a nonconforming use, once substantially abated (subject to the underlying zoning ordinance), may only be reestablished consistent with the provisions herein.
Any permit or variance granted pursuant to the provisions of this chapter may be conditioned according to the process described in § 460-705.06 to require the owner of the structure or object of natural growth in question to permit the municipality, at its own expense, or require the person requesting the permit or variance, to install, operate, and maintain such marking or lighting as deemed necessary to assure both ground and air safety.
Subject to that in this chapter.
Subject to the process in this chapter.
Where there exists a conflict between any of the regulations or limitations prescribed in this chapter and any other regulation applicable to the same area, the more stringent limitation or requirement shall govern and prevail.
The purpose of the MPO Master Plan Overlay is to provide property owners in the Township with opportunity to create mixed-use development inclusive of residential and nonresidential land uses in areas of the municipality that have existing infrastructure and capacity to support redevelopment limited residential dwellings alongside moderately sized commercial uses. Oriented to create a pedestrian experience, this mixed-use area promotes walkability of residents and visitors to promote increased mobility and animate the commercial spaces.

A. 
The purpose of the development approval process is to encourage owners to unitize or assemble large parcels of land to create a coordinated and well-conceived development which otherwise may not be created on small parcels of land. The major unified mixed-use land development is an optional mechanism that permits owners and the municipality to promote and encourage ingenuity in the layout and design of coordinated projects to more effectively improve and enhance sensitive natural resources, open spaces, existing infrastructure, connectivity and smart growth principles by allowing flexibility in the site layout from requirements in the underlying zoning district. The applicant shall be required to meet with the Township Municipal Authority to review required sanitary sewer lines and other sanitary sewer facilities including proposed rights-of-way to be identified, mapped and described as well as the capacity the proposed project will necessitate. All applicable provisions of the Township Municipal Authority shall apply.
(1) 
this major unified land development is permitted by conditional use in the overlay.
(a) 
The only land uses authorized in a major unified land development shall be those permitted by right or by conditional use within the overlay. Authorized land uses permitted by conditional use shall meet the conditional use requirements as set forth by Article XIII of this chapter.
(b) 
Specific application requirements respond to the unique natural and geographic conditions, as well as the scale and style of the development in the area. Consistent with the Pennsylvania Municipalities Planning Code Traditional Neighborhood Development provisions, the major unified mixed-use land development approval process includes submission of a Master Development Plan that addresses all applicable requirements of this chapter. Applicants are encouraged to provide for design standards that maintain development patterns of existing neighborhoods and encourage a mix of land uses that are complementary to the surrounding neighborhoods. Additionally, applicants are encouraged to enhance vehicular and pedestrian connectivity, reduce traffic congestion, and provide community services that are complementary to the surrounding neighborhoods. As presented through building elevations illustrating the entire block in which an application is proposed, the applicant shall ensure compatibility of building form and character exists between existing and proposed improvements.
(2) 
Property requirements for major unified mixed-use land development.
(a) 
Site requirements. Property subjected to major unified mixed-use land development approval shall, at the time of first approval, meet the following site requirements:
[1] 
Ownership. The entire site for the major unified mixed-use land development shall:
[a] 
Be owned or controlled (i.e., contract purchaser, ground lease, etc.) by the developer; or
[b] 
The owners of all the land shall submit a document in recordable form and in a form approved by the Township Solicitor binding all owners to comply with the major unified mixed-use land development approved by the conditional use approval.
[2] 
Minimum site area. The site subject to the major unified mixed-use land development shall be greater than one acre.
[3] 
Frontage. The minimum frontage abutting on a public right-of-way shall not be less than 150 feet.
[4] 
Access. The lot must provide for direct points of ingress and egress in a manner to assure convenient and safe access, which will not cause undue congestion or hazards on local roads.
[5] 
Each lot shall, to the greatest extent possible, preserve sensitive environmental features, existing wooded areas and historical resources.
(3) 
Approval of a major unified mixed-use land development. The Board of Supervisors shall approve or deny the major unified mixed-use land development in accordance with the provisions of this section as a conditional use. Prior to granting approval or denying a conditional use application, the proposal shall first be forwarded to the Township Planning Commission and may be forwarded to the Washington County Planning Commission for review and comment. Furthermore, a minimum of one public hearing shall be held by the Board of Supervisors pursuant to public notice within 60 days of the applicant's request for a hearing. This time period may be extended if both parties agree to the time extension, in writing.
(4) 
Major unified mixed-use land development application and requirements.
(a) 
Applicants seeking major unified mixed-use land development approval are required to contact the Township to discuss their project prior to any submission. During this time, the Township desires to review any associated sketch plans which should meet the requirements of Chapter 390, Subdivision and Land Development, prior to formal submission of a major unified mixed-use land development under this section. It is also advisable to present a sketch plan to the Township Planning Commission and the Board of Supervisors for informal discussions. Following sketch plan submissions, when one is submitted, or prior to formal submission of the Major unified mixed-use land development for consideration of conditional use approval, applicants shall be required to submit major unified mixed-use land developments depicting development on properties.
(b) 
The submission for major unified mixed-use land development approval shall include an application, site plans, proposed development plan and any required engineering reports that are deemed necessary by the Township to determine compliance with applicable sections of the Township Code. The application shall also be accompanied by a fee as may be set forth from time to time by resolution of the Board of Supervisors.
(c) 
Such plans and other materials shall not be required to meet the standards prescribed for preliminary or final land development approval or for the issuance of a building permit so long as they provide reasonable detail of the proposed use or development and a sufficient basis for a determination as to its compliance with these regulations. The plans and other documents shall be provided in the same number as comparable documents required for preliminary subdivision and/or land development under plan processing Chapter 390, Subdivision and Land Development.
(d) 
Incomplete application. The Township shall review the application within seven days of submission for completeness in accordance with the requirements of this chapter. If an application is found to be incomplete, the application shall be rejected; the Township shall notify the applicant, in writing, citing the specific deficiencies and the specific requirements of this chapter that have not been met.
(e) 
Plan distribution. The Township shall forward one copy each of the complete major unified mixed-use land development application to the Planning Commission, the Township Engineer, the Township Municipal Authority, the Washington County Planning Commission, and other such consultants, agencies and boards as are deemed necessary to provide a comprehensive review of the materials.
(f) 
Deficient application. If the Township determines that the plans and application do not meet numerous and/or significant requirements of the Township's Code of Ordinances, the Township shall give the applicant an opportunity to withdraw the plan for correction and refiling, without an additional Township filing fee, unless an additional public notice is required, then the fee shall be equal to the cost of the notice. This allowance shall be permitted on a one-time basis.
(5) 
Major unified mixed-use land development site requirements.
(a) 
Density bonus. For those applicants/owners that complete the major unified mixed-use land development approval process, the permitted residential densities of the underlying base zoning district may be increased by up to the following percentages:
