(a) Approval of a permit applied for under the provisions of Section 909.03
shall not be granted if the minimum slope or pitch proposed shall be less than one-eighth of an inch or the maximum more than five-eighths of an inch per foot. All slopes shall be in the direction of the curb. No curbs shall be approved that are less than five inches in height or more than seven inches in height, except where a lower curb is necessary for driveways crossing the sidewalk, which shall be shown on the profile thereof. However, the building official may in cases of undue hardship or special circumstances approve lesser or greater curb heights.
(b) All sidewalks shall be constructed in a smooth and even manner, and on a plane with the curb.
