Who pays for drainage projects

(a) Except as otherwise provided, the city may pay the entire cost for the following types of drainage facilities: (1) Public stream improvements; (2) Bridge to replace an existing bridge; (3) Relief drains that will take care of the drainage requirements of the existing land use; provided that if a property owner desires the construction of a larger facility to meet the drainage requirements attributable to a proposed higher land use of such person’s property, the city may construct such larger facility provided that the property owner bears the additional cost of such enlarged facility; and (4) Remedial work for the disposal of water collected or accumulated on public streets or remedial work necessitated by the disposal of such water over land not heretofore subject to such disposal, or both. (b) Except as otherwise provided, the city may participate in remedial work to existing private drainage facilities, situated in or abutting on private properties, for the resolution of localized drainage problems to the extent of the cost of engineering and 50 percent of the cost of construction. Examples of such drainage facilities are: (1) Stream walls to minimize erosion or to prevent flooding where such walls will show some public benefit; and (2) Drainage facilities to resolve seepage problems in the sidewalk area. )
