It is unlawful for any person, firm or corporation owning or having charge or control of any building, lot or premises in the City fronting on a paved street where a sidewalk is laid, either as owner, lessee, tenant, or otherwise, to allow upon any part of the entire width of the sidewalk area along said building, lot or premises, from curb to lot line, grass, weeds, dirt, rubbish or other obstructions or materials which, from any cause whatever, shall have accumulated or may accumulate or grow upon said sidewalk area above the established grade of the same. Such obstructions or materials shall not be swept or otherwise allowed or caused to go into the roadway or drainage structures. Provided, however that except as otherwise provided in Chapter 12.44, nothing herein contained shall be construed to require the removal from the borders of any sidewalk any ornamental plant, lawn, shrub, or tree of a reasonable growth, provided that the same are not in any manner obstructions to the free use of such sidewalk by pedestrians.
