R1 Low-Density Residential District. The intent of this district is to provide an area in the Borough for low-density residential development. The regulations herein are meant to foster a single-family residential environment on relatively large lots, and to prohibit all activities of a commercial or industrial nature.

R2 Moderate-Density Residential District. The intent of this district is to provide areas within the Borough for single- and two-family dwellings while preserving the character of the areas included in the district.

R3 High-Density Residential District. The intent of this district is to provide for and encourage a suitable family environment at a higher density than the R1 or R2 Districts. The regulations herein are meant to foster a residential area with various dwelling types.

R4 Mixed Residential District. The purpose of the Mixed Residential District is to provide an area within the community where a variety of residential types, styles, and densities can be planned and located in compatibility with one another. Such carefully planned developments should assure maximum usage of the Borough's undeveloped land and provide desirable, affordable options for future residential buyers while maintaining the natural and aesthetic values and qualities of the community for future generations.

CBD Central Business District. This district, with complimentary office, medical, civic and historical areas, forms the core for commercial, financial, professional, governmental and cultural activities. While all of these activities are permissible when located on the first floor of buildings in the district, productive mixed uses, including residential uses, are encouraged on upper floors. The intent herein is to protect and improve the central business district for the performance of its primary business and business-related functions. In addition, uses are discouraged which do not require a central location which would create friction in the performance of a function which should be centralized.

C General Commercial District. This commercial district is for personal and business services, general retail and wholesale business. Land areas included in this zoning category consist of areas where commercial development has displaced or is displacing residential development or is occupying vacant space. The regulations for this zone are intended to guide future change so as to discourage the formation of future commercial slums; to preserve the carrying capacity of the roads; and to provide for off-street parking and loading. It is not the intent of this district to encourage the extension of existing "strip" commercial areas along roads, but rather to provide concentrations of general commercial activities.

I Industrial District. It is the purpose of this zone to encourage the continuity and expansion of existing industrial operations and promote new industrial investment in the Borough. Uses that would substantially interfere with industrial development or expansion are prohibited by the regulations for this zone. The district's intent is to support the maintenance and expansion of such uses so that they may contribute to the economic base of the community and provide local employment opportunities.

H Historic Preservation District (Overlying District). The purposes of this overlying district are to promote the retention of community character through the preservation of local heritage by recognition and protection of historic resources; mitigate the negative effects of proposed changes to historic properties; encourage the continued use of historic properties and facilitate appropriate rehabilitation and adaptive reuse; encourage the preservation of historic settings and landscapes; discourage the demolition of historic resources, and utilize historic preservation as a tool for economic revitalization of the Borough. In the Historic Preservation zone, development or use of land shall be permitted in accordance with the regulations of the underlying district and the provisions set forth in Article VII of this chapter.

FF Flood-Fringe District (Overlying District). The intent of this district is to prevent the loss of property and life; the creation of health and safety hazards; the disruption of commercial and governmental services; and the extraordinary and unnecessary expenditure of public funds for flood protection and relief. To achieve this end, permitted uses must be floodproofed against flood damage. (See Article VI.) In these floodplain areas, development and/or the use of land shall be permitted in accordance with the regulations of the underlying district, provided that all such uses, activities, and/or development shall be undertaken in strict compliance with the floodproofing and related requirements of this and all Borough codes and ordinances.

FW Floodway District (Overlying District). The intent of this district is to prevent the loss of property and life; the creation of health and safety hazards; the disruption of commercial and governmental services; and the extraordinary and unnecessary expenditure of public funds for flood protection and relief. To achieve this end, only those uses which will not cause an increase in flood heights, velocities, or frequencies will be permitted in this district. (See Article VI.) In addition, in the Floodway District, no development shall be permitted except where the effects of such development on flood heights is fully offset by accompanying stream improvements which have been approved by all appropriate local and/or state authorities and notification of such has been given to the Federal Insurance Administration and the Pennsylvania Department of Community and Economic Development.

The locations and boundaries of the zoning districts are hereby established as shown on the Official Zoning Map, which is made a part of this chapter together with all future notations, references and amendments.[1]

No change of any nature shall be made to the Official Zoning Map, except in conformance with the procedures set forth in § 286-90 of this chapter. The final authority as to the current status of zoning districts shall be the Official Zoning Map. Any changes made to the zoning districts shall be made on the Official Zoning Map promptly after the amendment has been approved by the Borough Council.

Designation of district boundaries. The district boundary lines, except for the floodplain districts, are intended to generally follow the center lines of streets, highways, railroad rights-of-way, existing lot lines, municipal boundary lines, or streams or may be designated on the Official Zoning Map by a specific dimension from a road center line or other boundary as indicated.

Determination of district boundary locations. Where uncertainty exists with respect to the actual location of a district boundary line in a particular instance, the Zoning Officer shall request the Zoning Hearing Board to render its interpretation with respect thereto; provided, however, no boundary shall be changed by the Zoning Hearing Board. (The Board may request recommendations from the Borough Planning Commission prior to making such decisions.) If the true location of the boundary cannot be determined by interpretation of the Zoning Hearing Board, a request for corrective action shall be filed with the Borough Council.

Severed lots. Where a district boundary line divides a lot which was in single ownership at the time of adoption of this chapter or amendment thereto, the Zoning Hearing Board may permit the extension of the regulations for either zone into the remaining portion of the lot for a distance not to exceed 50 feet beyond the district line, provided that they determine such extension is consistent with the purposes of this chapter, including all floodplain management regulations.
