References in this title to less restrictive or more restrictive zoning districts refer to the General Zoning Districts listed in Section 17.20.030. The above districts are ranked and represent a progression from the most restrictive (A-E Exclusive Agricultural) to the least restrictive (I-H Heavy Industrial) classifications. In general, a use that is permitted in one zoning district would not be permitted in a more restrictive zoning district and may not be permitted in a less restrictive zoning district. (Ord. 706 § 3 (Exh. A), 2019).
