(A) General responsibilities. The city will be responsible for providing necessary drainage facilities on city-maintained streets within dedicated rights-of-way to accommodate existing storm flow or increased flow from development, and for maintaining drainage facilities on all city-maintained streets within dedicated rights-of-way. Inasmuch as civil law provides that lower lands are subservient to upper lands for natural drainage flowing to it, the city cannot be responsible for problems on private property that result from acceleration of flow from development by the city or others that becomes the natural burden of lower lands, or other drainage problems on private property.
(B) Specific policies. The city will provide and pay for all work that is necessary in order to provide adequate drainage of city streets. The city will not enter upon private property to pipe drainage ditches, maintain drainage ditches, or to correct drainage problems other than what is necessary to provide adequate drainage for city streets. The city will not become involved in disputes between adjoining property owners involving drainage problems. Improvements to drainage facilities along city streets requested by a property owner that are not necessary for providing adequate street drainage shall be at the expense of the property owner. Such improvements would consist of piping ditches along city streets, providing rip-rap slope protection, providing concrete ditch channels, or increasing the size of an existing culvert for the benefit of the property owner. Improvements or alterations to drainage facilities on city streets must be approved by the city engineer.
