17-1-0600 General rules of interpretation.
   17-1-0601 Numbering Style. The first two numerals in a section number correspond to the Title of the Municipal Code in which the section is located – Title 17 in the case of this Zoning Ordinance. Chapter numbers are found between the first and second dashes in the section number. Thus "17-1-XXXX" identifies the first chapter of Title 17. The first two numerals following the second dash identify the section number. The third and fourth numerals following the second dash identify the subsection number. Thus, "17-1-0601" identifies Title 17, Chapter 1, Section 6, subsection 1.

For example, if a maximum limit of one dwelling unit for every 2,500 square feet is applied to a 6,250 square foot lot, the resulting fraction of 2.5 is rounded down to 2 (allowed dwelling units).
