The Signal Hill Municipal Code, originally published by Book Publishing Company in 1979, has been kept current by regular supplementation.
   During original codification, the ordinances were compiled, edited and indexed by the editorial staff of Book Publishing Company under the direction of the city attorney.
   The code is organized by subject matter under an expandable three-factor decimal numbering system which is designed to facilitate supplementation without disturbing the numbering of existing provisions. Each section number designates, in sequence, the numbers of the title, chapter, and section. Thus, Section 18.12.050 is Section .050, located in Chapter 18.12 of Title 18. In most instances, sections are numbered by tens (.010, .020, .030, etc.), leaving nine vacant positions between original sections to accommodate future provisions. Similarly, chapters and titles are numbered to provide for internal expansion.
   In parentheses following each section is a legislative history identifying the specific sources for the provisions of that section. This legislative history is complemented by an ordinance disposition table, following the text of the code, listing by number all ordinances, their subjects, and where they appear in the codification.
   Footnotes referring to applicable statutory provisions are located throughout the text. A subject-matter index, with complete cross-referencing, locates specific code provisions by individual section numbers.
   This supplement brings the code up to date through Ordinance 2023-02-1543, passed 3-14-23.
