Boundaries established. The boundaries of the various zoning districts are hereby established on the map entitled "Official Zoning Map" on file in the office of the Borough Manager. The Zoning Map with all explanatory matter thereon is hereby made part of this chapter. The Map shall be dated and shall carry the Borough Seal and the signature of the President of Council and the Borough Secretary certifying that it is the true map adopted by Council. A record of all amendments to the Map shall be kept on file in the Borough Manager's office. All such amendments shall be identified on the Map and similarly certified. The boundaries between districts are, unless otherwise specifically indicated, either the center line of street rights-of-way or such other lines extended, or parallel lines thereto, or property lines or other physical boundaries or features. Where streets, property lines or other physical boundaries or features are not applicable, boundaries shall be determined using the scale shown on the Map.

Interpretation. Where physical boundaries or features existing on the ground are at variance with those shown on the Official Zoning Map or in other circumstances not specifically covered above, the Planning Commission shall interpret the district boundaries.

Future street vacation. In the event that a thoroughfare shown on the Official Zoning Map is vacated, the property formerly in said right-of-way shall be included within the zoning district of the adjoining property on either side of said vacated right-of-way. Where said thoroughfare forms a district boundary, the new boundary shall be the new property line created by the former center line of the vacated thoroughfare.
