The zoning district locations and boundaries are those that exist on the legally adopted Official Zoning Map, a copy of which is attached hereto and made a part of this chapter.[1] The original Zoning Map shall be kept on file in the office of the Borough Secretary. Whenever changes are made in the boundaries or other matter included on said Zoning Map, such changes shall be made by the Borough Engineer within five days after the amendment has been approved by the Borough Council. In interpreting the language of this chapter to determine the extent of the restriction upon the use of the property, the language shall be interpreted, where doubt exists as to the intended meaning of the language written and enacted by the Borough Council, in favor of the property owner and against any implied extension of the restriction.
