No person shall construct, or cause to be constructed, in connection with any structure upon a lot abutting upon any of the streets of the City wherein there is a gutter providing drainage into a storm sewer, a downspout or drain which shall discharge water in any other manner than in such gutter. Each downspout or drain discharging water into any street in the City shall be conducted under the sidewalk to the gutter. No downspout or drain shall, in any event, be so constructed as to discharge water into any alley in the City, unless such alley is so constructed as to drain such water into a storm sewer. No such downspout or drain shall be constructed until a certificate and permit therefor have been obtained from the City Manager; provided, that in no case shall the property owner allow roof drainage to run onto the property of adjoining landowners.
