18.83.040   Addressing.
   A.   Address numbering concept: The address numbering concept used in this chapter is point-of-origin/baseline. North-south and east-west baselines shall be established for each address system. The intersection of the north-south and east-west baselines shall be the point-of-origin. Numbering shall increase in the north, south, east and west directions from the point-of-origin.
   B.   Address Systems. Discrete areas of Pima County shall be given their own baselines, points-of-origin, grids radiating from the points-of-origin, and street numbers.
      1.   Address systems shall be established only in areas which will not overlap other address systems, however distant.
      2.   If an existing address system expands to overlap another address system, a dominant system shall be selected, and:
         a.   The nondominant system shall have limits established to restrict further expansion; or
         b.   The nondominant system shall be abandoned and readdressed to conform to the dominant system.
      3.   A grid shall be based upon the standard land surveying construct of section, township and range.
      4.   The section (one square mile) shall be the primary grid division with:
         a.   Each section line divided into eight equal parts, each part being a hundred block; and
         b.   Each hundred block divided into equal numeric increments 0 through 99;
         c.   Hundred block numbers shall be established on each section line, quarter-section line, sixteenth-section line, and sixty-fourth section line;
         d.   Hundred block numbers shall be displayed on each section line of the hundred block base map for each address system;
         e.   Existing sections with nonconforming hundred blocks shall remain unchanged.
   C.   The following address systems are established:
      1.   Tucson.
