None of the duties or privileges imposed or conferred by this subchapter 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 permit therefor. No material removed from any sidewalk shall be placed upon any portion of any adjacent street, alley, place or square. All refuse, lumber or debris remaining after the completion of any sidewalk repair or renewal 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 any street, alley place or square, within 48 hours after being notified by the City Foreperson to do so, 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 City Foreperson 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 or repair of sidewalks.
