The locations and boundaries of the areas classified within each of these zoning districts and overlays are set forth on the Zoning Map attached hereto and made a part hereof by this reference and adopted at the time of enactment of this chapter. All notations, references, explanatory matter and other information on the Zoning Map are adopted and incorporated herein by this reference. The Zoning Map shall be kept on file for public inspection in the business office of the Borough.
The zoning district and overlay boundaries shall be shown on the Zoning Map with different-colored areas.
A. 
Where district and overlay boundaries are indicated as approximately coinciding with the center lines of streets, ways, alleys, highways, railroad lines or streams, such center lines shall be construed to be such boundaries.
B. 
Where district and overlay boundaries are indicated as approximately coinciding with plotted lot lines, such lot lines shall be construed to be such boundaries, or where district and overlay boundaries are indicated as extensions of plotted lot lines or connections of the intersections of plotted lot lines, such lines shall be construed to be such boundaries.
C. 
Where district and overlay boundaries are indicated as approximately parallel to center lines of streets, alleys, ways, highways, railroad lines or streams, lot lines or other physical features, such district and overlay boundaries shall be construed as being parallel thereto and at such distance therefrom as indicated on the Zoning Map, provided that distances not indicated specifically on the Zoning Map shall be determined by measurement according to the scale of the Zoning Map.
D. 
In cases where district and overlay boundaries as shown on the Zoning Map do not coincide or approximately coincide with streets, ways, alleys, highways, railroad lines, streams, or plotted lot lines, and no dimensions are shown on the Zoning Map, the location of such boundary lines shall be determined by the use of the scale appearing on the Zoning Map.
E. 
Where physical or natural features existing on the ground are at variance with the district and overlay boundaries as shown on the Zoning Map or as interpreted pursuant to this section, the Zoning Hearing Board, upon application, shall interpret the district and overlay boundaries.
F. 
Where any land within the municipal boundaries of the Borough is unzoned and shown on the Zoning Map with the color white, such as the land areas known as Interstate 79 and Interstate 279, the land shall be interpreted as being within the immediately adjacent zoning district with which the subject land shares the majority of its property line.
