34.1.4 Map Designation. When combined with a principal zone, the Development Standard Combining Zone shall be designated on the adopted zoning maps by the designator “S,” except as provided herein. The “S” designator shall immediately follow the principal zone designator, or, where applicable, shall immediately follow the maximum density designator. The development standards that are modified shall also be represented on the adopted zoning maps in a table format in the order listed in this section. Arabic numerals shall be used in the table to specify all modified development standards, except for permitted principal building types. Permitted building types shall be represented by name in the table. Minimum Lot Size shall be represented by a number which represents thousands of square feet, followed by the lower case letter “s,” or by a number which represents numbers of acres, followed by the lower case letter “a,” whichever is appropriate.
