(3) Gaps. Gaps between slabs in excess of one inch in width, or those caused by the absence of a fragmented section of the sidewalk exceeding one inch in width;
(4) Surface quality.
A. Cracked slabs. Slabs fragmented by cracks into four or more sections, where any one of the gaps between fragments is greater than one-fourth inch in width;
B. Pitted slabs. Slabs whose surface is granular and contains depressions in excess of one-half inch in depth; and
C. Depth. To be determined by a two-foot straight edge laid on the surface of the sidewalk; and
