It is unlawful to plant within thirty feet of any public or private sewer any willow, poplar, cottonwood, soft maple, gum tree, or any other tree or shrub whose roots are likely to enter and obstruct the flow of said sewers.

The City Engineer is authorized to remove any trees or shrubs from any public street or the roots of any trees or shrubs which extend into any public street when such trees, shrubs or the roots thereof are obstructing or are liable to obstruct any public or private sewer or drain. Before making any such removal, the City Engineer shall give ten days notice in writing to the owner or occupant of the abutting property or the property on which such trees or shrubs are growing, requiring the owner or occupant to remove the same. If the written notice cannot be given to the owner or occupant, the notice may be posted on the premises or in the street at the location of the trees or shrubs requiring such removal. If the owner or occupant fails or refuses to remove such trees or shrubs and roots within the time specified, the City Engineer is authorized to do so and the cost thereof shall be charged to the owner or occupant. Upon giving such written notice of the amount thereof to the owner or occupant or by posting such notice at the location of the trees or shrubs, the cost thereof shall be immediately payable to the City Treasurer by such owner or occupant. (Ord. 208 § 38, 1957).
