Where an unimproved lot is situated between two improved lots which were developed prior to the enactment of this chapter, the front yard requirement of the unimproved lot may be modified to be the average of the existing front yards of the two improved lots, provided the proposed principal building is within 50 feet of both existing principal buildings.

Where an improved lot is adjacent to one improved lot which was developed prior to the enactment of this chapter, the front yard requirement of the unimproved lot may be modified to be equal to the existing front yard of the improved lot, providing the proposed principal building is within 50 feet of the existing principal building.

For the purpose of this section, an "unimproved lot" shall be the same as a vacant lot; and an "improved lot" shall be one on which a principal building is erected.

The height limitations of this chapter shall not apply to church spires; farm structures when permitted by other provisions of this chapter (e.g., silos, barns, etc.); belfries, cupolas, penthouses and domes not used for human occupancy; chimneys, ventilators, skylights, water tanks, bulkhead and similar features; utility poles and standards; and necessary mechanical appurtenances usually carried above the roof level. Such features, however, shall be erected only to such height as is necessary to accomplish the purpose they are to serve and then only in accordance with any other governmental regulations.

In any district, any building may be erected to a height in excess of that specified for the district only by a special exception granted by the Zoning Hearing Board.

Corner lots.

Through lots. Where a lot extends through from street to street, the applicable front yard regulations shall apply on both street frontages. However, in the event of a complete system of through lots which are designed for reversed frontage, the front yard need only be along the more minor street of the subdivision.

Flag lots. Flag lots shall not be created when lots can be designed to provide full frontage along a street. Flag lots shall conform to the requirements of Chapter 390, Subdivision and Land Development.

Irregularly shaped lots. In the case of irregularly shaped lots, the minimum lot width specified in the district shall be measured at the minimum required front building setback line, provided that in no case shall the lot frontage measured at the street right-of-way line be less than 70% of the minimum lot width, except in the following situations: on culs-de-sac or street center-line curves of less than 300-foot radius, where the lot frontage measured at the street right-of-way line shall not be less than 40% of the minimum lot width.

Projections into required yards.

Every building and structure hereafter erected or moved shall be on a lot abutting a street, or on a lot for which a legally recorded right of access to a street or approved private street exists.

All buildings shall be located on lots so as to provide safe and convenient access for servicing, fire protection, and required off-street parking.

After the effective date of this chapter, no lot shall be created which does not abut a street meeting all design criteria within Chapter 390, Subdivision and Land Development, for either a local, collector or arterial street.

A written statement describing the proposed use.

The location and dimensions of all buildings, structures, parking areas, traffic access and circulation drives, open spaces, landscaping and other pertinent information.

The names and addresses of adjoining property owners, including properties across a street right-of-way.

Ground floor plans and building elevations of proposed structures.

Existing contour lines and floodplain delineation lines.

Estimated traffic amounts generated by the proposed use.

Pennsylvania Department of Transportation highway occupancy permits, erosion and sedimentation control plan, and sewage and well permit approvals by their respective agencies.

Subdivisions. The division or redivision of a lot, tract or parcel by any means into two or more lots, tracts or parcels, or other divisions of land, including changes in existing lot lines, not specifically exempted by Chapter 390, Subdivision and Land Development.

Land developments. A group of two or more residential or nonresidential principal buildings, whether proposed initially or cumulatively; or a single nonresidential building on a lot or lots regardless of the number of occupants or tenure; or the division or allocation of land or space, whether initially or cumulatively, between or among two or more existing or prospective occupants by means of or for the purpose of streets, common areas, leaseholds, condominiums, building groups or other features; or the conversion of an existing single-family detached dwelling or twin dwelling unit into a total of four or more dwelling units.

The issuance of a temporary use or structure permit shall not be detrimental to land use activities normally permitted in the zoning district. This use should contribute materially to the welfare of the Township, particularly in a state of emergency.

The Zoning Officer shall establish a reasonable maximum time limit, which shall be stated on the permit. In no case shall the permit exceed an absolute maximum life of one year (except in case of a state of emergency).

Upon expiration of the permit, the use shall cease, and such structure or use shall be completely removed without cost to the Township.
