In order to make the individual zone chapters easier to read, supplementary regulations or specialized topics applied more broadly than at a specific zone level, such as landscaping, parking, signage, and nonconforming uses, are discussed separately. Chapters 18.50 through 18.56 ACC provide detailed information on these and similarly broad topics. While the relevant portions of these sections will be referenced by the zone-specific chapters, these chapters are also a good place to look for information on existing or proposed land uses not explicitly listed elsewhere in the code. (Ord. 6245 § 1, 2009.)
