"More restrictive uses," as employed in this title, means the following:

The location and boundaries of the various zones are such as are shown and delineated on the zoning map of the city, which map is on file in the office of the City Clerk and made a part of this title.

The zoning map may, for convenience, be divided into parts, and each such part may, for purposes of more readily identifying areas within such zoning map, be subdivided into units, and such parts and units may be separately employed for purposes of amending the zoning map or for any official reference to the zoning map.

Changes in the boundaries of the zones shall be made by ordinance adopting an amended zoning map, or part of the map, or unit of a part of the zoning map, which amended maps, or parts or units of parts, when so adopted, shall be published in the manner prescribed by law and become a part of this title.

Where uncertainty exists as to the boundaries of any zone shown upon a zoning map or any part or unit thereof, the following rules shall apply:

Any unprezoned property which is annexed to the city and any property within the city limits which is unzoned is automatically zoned L-C. Unincorporated territory or property adjacent to the city may be prezoned for the purpose of determining a zone which will apply to such property in the event of subsequent annexation to the city. The method of accomplishing such prezoning shall be the same as that for changing zones on property within the city. Such zoning shall become effective at such time as the annexation becomes effective.

Except as provided in this title, no building shall be erected, reconstructed or structurally altered, nor shall any building or land be used for any purpose except as hereinafter specifically provided and allowed in the same zone in which such building and land is located. Cardrooms (Ch. 5.12), retail sales of dogs and cats (Ch. 7.16), camping on public property (Ch. 8.36), mini-satellite wagering (Ch. 8.80) and cannabis activities (Ch. 8.90) prohibited elsewhere in this code are also prohibited as land uses under this title.

Where a number follows the zoning symbol on the zoning map, it shall represent the minimum lot area required in lieu of the minimum area established in each zone as herein defined. If the number is a thousand or larger, it refers to square feet. If the number is a hundred or less, it refers to acres. If no number follows the zoning symbol, the area prescribed in the chapter governing such zone shall apply.

As provided by the Carlsbad General Plan, some areas of the city are suitable for more than one land use classification; and often, multiple land use designations are assigned to areas in the early planning stages when it is unclear what the most appropriate designation may be or where the boundaries of such designations should be located. These areas are referred to in the general plan as "combination districts." It is the intent of this section to implement the general plan provisions for "combination districts," as follows:
