Any person, firm or corporation, which now has a tin horn or culvert or other drainage material, constructed in such manner so that it interferes unduly with the flow of water along said drainage ditch, shall repair such tin horn, culvert or other drainage material in such manner so that the same will not interfere with the flow of such water along such streets and alleys. The city manager is hereby directed to notify such person of the defective tin horn, culvert or drainage material and request that the same be repaired. Upon failure of the person, firm or corporation to make such repairs within four (4) weeks after being so notified, then such person, firm or corporation shall be deemed guilty of an offense.
