A.   None of the duties or privileges imposed or conferred by this chapter shall in any way be deemed to authorize or allow the obstruction of any street, either during or after any work upon any sidewalk, except under the permit therefor.
   B.   No material removed from any sidewalk shall be placed upon any portion of any adjacent street, alley, place or square, unless allowed to do so pursuant to the terms of the permit.
   C.   All refuse, lumber or debris remaining after the completion of any sidewalk construction, repair or replacement shall be removed from the street forthwith, and any owner, lessee or tenant of abutting property who shall fail to remove any such obstruction from the street, alley, place or square within forty eight (48) hours after being notified by the director of public works so to do, shall be deemed guilty of maintaining a public nuisance and shall be subject to the penalties prescribed therefor. In case of failure to remove obstructions after such notice, the director of public works shall cause the same to be removed and shall charge the full cost of such removal to such owner, lessee or tenant, and the charge shall become a lien upon such abutting property and shall be collected as hereinbefore provided for the collection of cost of construction, repair or replacement of sidewalks.
