§ 425-50 Overlay zoning districts.

A. Purpose and intent. The purpose of Article XI of this chapter is to:

(1) Provide a framework for enabling legislation to aid in the creation of various overlay zoning districts, each with special regulations, requirements and standards;

(2) Provide a description of special regulations, requirements and standards associated with each overlay zoning district; and

(3) Provide guidelines for the application of each overlay zoning district created to assure conformity with the purpose and development objectives of the applicable overlay zoning district.

B. General provisions.

(1) This Article XI of this chapter establishes overlay zoning districts that include additional specific regulations, requirements and standards of limited application to certain designated areas within Paxtang Borough.

(2) Overlay zoning districts provide additional considerations for development within specific designated areas of Paxtang Borough that are identified as possessing special and/or unique conditions, characteristics, circumstances and/or resources of importance, interest and/or value to Paxtang Borough. Such overlay zoning districts are established for the purposes of protecting the health, safety and general welfare, and furthering the community development objectives set forth in Article I of this chapter relating to purpose of enactment.

(3) Overlay zoning districts may encompass one or more applicable underlying or base zoning districts and impose additional or different regulations, requirements and standards than those which are required by the applicable underlying or base zoning districts.

(4) Applications for development are subject to the provisions of both the applicable underlying or base zoning district and the overlay zoning district.

(5) Although overlay zoning districts may be more or less restrictive than the applicable underlying or base zoning district, unless otherwise specified in this Article XI of this chapter, wherever and whenever the regulations, requirements, and standards of overlay zoning districts are at variance with the regulations, requirements and standards of the applicable underlying or base zoning districts, the most restrictive or that imposing the higher standards shall govern development.

C. Overlay zoning districts established. The following overlay zoning districts as set forth in Table 11-1 and associated special regulations, requirements and standards are hereby established, and the respective overlay zoning districts are shown on the "Borough of Paxtang, Dauphin County, PA: Zoning Map" listed in Article III of this chapter relating to Zoning Map: CI.

(2) Conical Surface Zone.

(3) Horizontal Surface Zone.

(4) Primary Surface Zone.

(5) Transitional Surface Zone.

[1] Editor's Note: Figure 11.1 is attached to this chapter.

E. Permit applications.

(1) As regulated by Act 164 and defined by 14 Code of Federal Regulations Part 77.13(a) (as amended or replaced), proposals for applications to: a) erect a new structure; b) add to or increase the height of an existing structure; or c) establish, erect and/or maintain any use, structure or object (natural or man-made) in the Airport Overlay Zoning District (APO), shall first notify PennDOT'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. PennDOT's BOA response shall be included with this permit application for it to be considered complete. If PennDOT's BOA returns a determination of no penetration of airspace, the permit request should be considered in compliance with the intent of this section, Airport Overlay Zoning District. If PennDOT'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 Subsection F below.

(2) Exceptions. In the following circumstances, notification of an approval by PennDOT's Bureau of Aviation (BOA) shall not be required:

(a) No permit is required for the routine maintenance and repairs to, or the replacement of, parts of existing structures which do not enlarge or increase the height of an existing structure.

(b) In the areas lying within the limits of the horizontal zone and/or conical zone, no permit shall be required for any tree or structure less than 185 feet of vertical height above the ground, except when, because of terrain, land contour or topographic features, such tree or structure would extend above the height limits prescribed for such zones.

(c) In the areas lying within the limits of the approach zones, but at a horizontal distance of not less than 4,200 feet from each end of the runway, no permit shall be required for any tree or structure less than 185 feet of vertical height above the ground, except when, because of terrain, land contour or topographic features, such tree or structure would extend above the height limit prescribed for such approach zones.

(d) In the areas lying within the limits of the transition zones beyond the perimeter of the horizontal zones, no permit shall be required for any tree or structure less than 185 feet of vertical height above the ground, except when such tree or structure, because of terrain, land contour or topographic feature, would extend above the height limit prescribed for such transition zones.

(e) Nothing contained in any of the foregoing exceptions shall be construed as permitting or intending to permit any construction or alteration of any structure or growth of any tree in excess of any of the height limits established by this Airport Overlay Zoning District, except that 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.

F. Variances. In addition to the provisions set forth in Article XVII of this chapter relating to the Zoning Hearing Board, any request for a variance shall include documentation in compliance with 14 Code of Federal Regulations 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 Federal Aviation Administration's (FAA) and PennDOT'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 Subsection I below.

(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. 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 purpose and intent in this section.

G. Use restrictions. Notwithstanding any other provisions in this section, no use shall be made of land, water or structure within the Airport Overlay Zoning District in such a manner as to:

(1) Create electrical interference with navigational signals or radio communications between the airport and aircraft;

(2) Make it difficult for pilots to distinguish between airport lights and others;

(3) Impair visibility within the Airport Overlay Zoning District of Paxtang Borough;

(4) Create bird strike hazards; or

(5) Otherwise endanger or interfere with the landing, takeoff or maneuvering of aircraft utilizing the airport(s).

H. Nonconforming uses, structures and/or trees. The regulations prescribed by this section shall not be construed to require the removal, lowering or otherwise change to or alteration of any use, structure and/or tree identified as nonconforming to the regulations of this section as of the effective date of this chapter, or to otherwise interfere with the continuance of a nonconforming use, structure and/or tree. No nonconforming use or structure shall be altered, nor tree permitted to grow higher, so as to increase the nonconformity (relating to height and the use restrictions set forth in this section). A nonconforming use, structure or tree, once abandoned or damaged or destroyed as per to the standards in Article XV of this chapter relating to existing nonconforming uses and structures, may only be reestablished consistent with the provisions of this section and Article XV of this chapter relating to existing nonconforming uses and structures.

I. Obstruction marking and lighting. Any permit or variance granted pursuant to the provisions of this section and Article XVII of this chapter may be conditioned according to the process described in Subsection F above to require the owner of the structure or object of natural growth in question to permit the Borough, 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.

§ 425-52 Floodplain Overlay Zoning District (FPO).

See Chapter 220, Floodplain Management, of the Code of the Borough of Paxtang, relating to floodplains.

§ 425-53 Development Compatibility Standards Overlay Zoning District (DCSO).

A. Application. The regulations, standards and guidelines contained in this section shall apply to applications for new development activity, specifically including but not limited to new uses, replacement, infill and redevelopment within the Development Compatibility Standards Overlay Zoning District of Paxtang Borough, unless otherwise noted in this chapter.

B. Purpose and intent. The purpose of the Development Compatibility Standards Overlay Zoning District is to:

(1) Protect and enhance the development patterns and characteristics of well established neighborhoods and other important character areas in Paxtang Borough by accommodating applications for new development activity, specifically including but not limited to new uses, replacement, infill and redevelopment that are consistent and compatible with the character and scale of the established development patterns and distinctive features of the neighborhoods and other important character areas via the development compatibility design guidelines and standards set forth in this section below.

(2) Address the purposes, objectives and standards of Article VII-A of the MPC.

(3) Provide a manual of written and graphic design guidelines to assist applicants in the preparation of proposals for new development activity specifically including but not limited to new uses, replacement, infill and redevelopment in accordance with Section 708-A of the MPC.[1]

[1] Editor's Note: See 53 P.S. § 10708-A.

C. Boundaries. The boundaries of the Development Compatibility Standards Overlay Zoning District are hereby established as shown on the Borough of Paxtang, Dauphin County, PA: Zoning Map listed in Article III of this chapter relating to the Zoning Map.

D. Permitted uses. Proposals for applications for new development activity, specifically including but not limited to new uses, replacement, infill and redevelopment, shall be permitted in accordance with the regulations of the applicable underlying or base zoning district, provided that all such uses, activities and/or development shall be undertaken in compliance with the development compatibility design guidelines and standards set forth in this section below.

E. Application of development compatibility design guidelines and standards. The development compatibility design guidelines and standards are enabled by Section 708-A of the MPC as the manual of written and graphic design guidelines.

(1) These development compatibly design guidelines and standards provide the Borough officials, residents, business owners, developers, builder, and other interested parties with a written and visual set of compatibility design standards and characteristics prevalent in and important to the protecting and enhancing of the established development patterns and features of neighborhoods and important character areas in Paxtang Borough.

(2) These design guidelines and standards provide the desired direction for applications for new development , specifically including but not limited to new uses, replacement, infill and redevelopment within neighborhoods and other important character areas in Paxtang Borough to ensure consistency and compatibility between new development, including new uses, replacement, infill and redevelopment, and established building and development types, styles and, patterns.

(3) In addition to the general building and land requirements set forth elsewhere in this chapter, proposals for development shall be consistent with the compatibility design standards and guidelines set forth in this section. If a design guideline or standard is not specifically indicated in these compatibility design guidelines and standards, refer to the most recent version of the Paxtang Borough Comprehensive Plan and/or other applicable plans adopted by Paxtang Borough, for additional information.

(4) These compatibility design guidelines and standards highlight important design characteristics relating to buildings and land development via written standards and visual images which are intended to provide guidance and inspiration for implementing the desired design concepts set forth in the most recent version of the Paxtang Borough Comprehensive Plan and/or other applicable plans adopted by Paxtang Borough. The images and visual examples of these design guidelines and standards are provided for general illustrative purposes only and shall not be construed to be operative language of the chapter. The written standards of these design guidelines and standards shall take precedence over the images and visual examples, and therefore govern.

(5) Applications for zoning and/or building permits.

(a) Limited applicability and compliance. The applicability of specific development compatibility design guidelines and standards are limited only to those specific guidelines and standards relating to and affecting the specific building and development features proposed, listed on, and applied for as part of a zoning and/or building permit application.

[1] Example 1: If an applicant for a zoning/building permit proposes to only enclose a front porch on an existing one-story building used for a single-family residential dwelling and which is located on a block and surrounded by three-story buildings, the only development compatibility design guidelines and standards that would apply would be limited to front porch enclosures only.

[2] Example 2: If an applicant for a zoning/building permit proposes to construct a new building to be used for a medical office on a vacant lot located on a block and surrounded by three-story buildings, then the development compatibility design guidelines and standards that would apply would include and not be limited to: building setbacks; building height; building orientation; building facades; building roofs; building footprint; lot access and parking; nonresidential uses within an enclosed building; refuse and servicing facilities; and hours of operation.

(b) In addition to the information required in Article XVII of this chapter, applications for new development activity, specifically including but not limited to new uses, replacement, infill and redevelopment in the Development Compatibility Standards Overlay Zoning District, shall be submitted with the following information unless the Zoning Officer determines such information is unnecessary to determine compliance with this section:

[1] A complete set of calculations (e.g., required building setbacks, building heights, lot access, etc.) used to determine and demonstrate compliance with all applicable standards set forth in this section below and the applicable underlying or base zoning district in which it is situated.

[2] A schematic architectural drawing of the principal building's proposed front facade(s).

(6) Development compatibility design guidelines and standards. Specific building and development compatibly design guidelines and standards shall apply to the following features:

(a) Front building setback.

(b) Building height.

(c) Building orientation.

(d) Building facade.

(e) Building roof.

(f) Reuse of existing or formerly residential building.

(g) Building footprint.

(h) Fire escape.

(i) Lot access and parking.

(j) Residential garage location and design.

(k) Nonresidential uses within an enclosed building.

(7) If new development activity, specifically including but not limited to new uses, replacement, infill and redevelopment in the Development Compatibility Standards Overlay Zoning District cannot to the maximum extent feasible be designed in accordance with the applicable standards in this section, the applicant shall demonstrate by credible evidence that the new development cannot to the maximum extent feasible be designed due to structural limitations of the building(s) and structure(s) and/or physical limitations and constraints of the lot. Persons aggrieved by the Zoning Officer's determination may appeal to the Zoning Hearing Board in accordance with Article XVII of this chapter relating to the Zoning Hearing Board.

F. Front building setback.

(1) Front building setbacks on the lot proposed for development shall respect and maintain the predominant development pattern, context and character of the principal buildings and other features on the abutting lots and, to the maximum extent feasible, shall incorporate the predominant character of the majority of the existing principal buildings on the same shared block face (between two intersecting streets) along the same side of the street.

(2) For a lot proposed for development, the distance that the front of the principal building is set back from the street right-of-way shall be similar to the distances between an existing principal building and the street right-of-way on abutting lots in accordance with the following standards:

(a) Identify the existing principal building on each lot abutting the lot proposed for development.

(b) Calculate the distances that the existing principal buildings are set back from the street rights-of-way line(s) on the abutting lots.

[1] If an abutting lot is vacant, the required building setback of the abutting vacant lot shall be assumed to be the front building setback standards required in the applicable underlying or zoning district in which it is situated.

[2] For corner lots, the standards set forth in this subsection shall be calculated using each abutting lot, which includes those abutting lots having frontage on and the existing principal buildings oriented toward the intersecting street.

(c) The front building setback for the building on the lot proposed for development shall be no closer toward (minimum) and no farther away from (maximum) the street right-of-way than the front building line of existing buildings on abutting lots, unless all buildings on the abutting lots have the same building setback distance.

[1] Covered front porches shall be permitted to fulfill this requirement.

(d) No building shall extend into any street right-of-way.

(3) Front building setback graphic examples.

(d) Figure 11.5, Compatible Front Building Setback: New Infill Building - Shiremanstown, PA.

(e) Figure 11.6, Typical Front Setback Conditions.

	Example 1: Front Setback Calculation for Lot B.
	Lot A and Lot C abut Lot B
		Lot A front setback = 0 feet
		Lot C front setback = 0 feet
	Since Lot A (0 feet) and Lot C (0 feet) have the same front setback, then Lot B shall have the same front setback (0 feet)
	Front building setback for Lot B = 0 feet

	Example 2: Front Setback Calculation for Lot E.
	Lot D and Lot F abut Lot E
		Lot D front setback = 10 feet
		Lot F front setback = 15 feet
	Since Lot D (10 feet) and F (15 feet) have different front setbacks, then Lot E shall be no closer than 10 feet (minimum) and no further than 15 feet (maximum) from the street right-of-way.
	Front building setback for Lot E = 10 feet minimum and 15 feet maximum

G. Building height.

(1) Roof heights, cornice lines, eaves, parapets and porches of the principal building on the lot proposed for development shall respect and maintain the predominant development pattern, context and character of the principal buildings and other features on the abutting lots and, to the maximum extent feasible, shall incorporate the predominant character of the majority of the existing principal buildings on the same shared block face (between two intersecting streets) along the same side of the street.

(2) For a lot proposed for development, the height of the principal building shall be similar to those principal building heights (in stories and/or feet) for existing principal buildings on abutting lots in accordance with the following standards:

(a) Identify the existing principal building on each lot abutting the lot proposed for development.

(b) Calculate the average number of stories and/or feet of the heights of the existing principal buildings on the abutting lots.

[1] If an abutting lot is vacant, the number of stories for an abutting vacant lot shall be assumed to be one story, unless the building height standards defined in the applicable underlying or base zoning district in which it is situated have a different minimum building height, in which case, the number of stories shall be that required by the applicable underlying or base zoning district.

[2] For corner lots, the standards set forth in this subsection shall be calculated using each abutting lot, which includes those abutting lots having frontage on and the existing principal buildings oriented toward the intersecting street.

[3] When determination of the number of stories and/or feet results in a requirement of a fraction, any fraction up to and including 1/2 may be disregarded, and fractions over 1/2 shall be interpreted as one story or one foot, as applicable.

[4] The height of the principal building shall not have less stories and/or height in feet than the shortest principal building on the abutting lots, and shall not have more stories and/or height in feet than the tallest existing building on abutting lots.
