Iowa Code § 468.42
The commissioners to assess benefits and make apportionment of costs and expenses shall determine and assess the benefits to the property of any railroad company extending into or through the levee or drainage district, and make return thereof showing the benefit and the apportionment of costs and expenses of construction. Such assessment when finally fixed by the board shall constitute a debt due from the railroad company to the district, and unless paid it may be collected by ordinary proceedings for the district in the name of the county in any court having jurisdiction. All other proceedings in relation to railroads, except as otherwise provided, shall be the same as provided for individual property owners within the levee or drainage district.
