No person, firm, company or corporation, nor the agent, representative or employee of any person, firm, company or corporation, shall plow or otherwise clear a parking lot, sidewalk, or any other private property of snow or ice and thereafter place, throw or deposit that snow or ice on any street, alley or sidewalk. Snow may be piled in paved parking right of way of a firm, company or corporation during snowfalls as long as it is removed within forty-eight hours of deposit. Snow and ice may also be piled by a firm, company or corporation on gravel parking right of ways only abutting its property as long as the snow or ice does not encroach on paved driving surfaces or create a sight-distance safety problem as will be determined by the city superintendent and/or police chief. Any firm, company or corporation may be asked at any time to remove some or all snow on public rights-of-way within a forty-eight-hour period or the city will remove such and bill the firm, company or corporation for the city’s cost plus fifteen percent.
