It is the privilege and, on notice from the Commissioner of
Public Works, it shall be the duty of any owner or occupant of any
premises to grade and level the sidewalk in front of said premises
between the street line and the curbline; however, the Commissioner
of Public Works may, at the expense of the City, undertake any necessary
grading in any area where federal funds are available, in full or
in part, for such grading and leveling; such grade shall in all cases
be at a fall of not more than 1/2 inch to the foot, except at driveways,
when the grade may be increased by the consent of the Commissioner
of Public Works, and except that where conditions require a change
in the grade of any sidewalk other than as herein provided, such change
may be made upon the approval of the Common Council.
The Commissioner of Public Works shall prepare plans and specifications
and shall annually advertise for bids for the construction, reconstruction
and repair of such sidewalks as shall be ordered during the twelve-month
period specified in such advertisement. Such bids shall be advertised
for and the contract for such work awarded as provided by Section
665 of the Charter.
No person, unless authorized by the Common Council, shall paint,
mark, write, print or stencil any letters, figures, pictures or characters
of any kind upon any of the public sidewalks or pavements, whether
for advertising purposes or otherwise.
