May, Justice.

Iowa would be much swampier if it weren’t for drainage districts, those

special government entities that construct and maintain water drainage systems.

But sometimes those systems need to be repaired or improved. When that

happens, the costs have to be assessed against the properties that will benefit.

In this case, we consider two questions about those assessments. Both

questions concern assessments against a particular kind of property: state-

owned highway land under the management of the Iowa Department of

Transportation (IDOT).

The first question is whether those assessments are subject to Iowa Code

section 307.45 (2023), which limits assessments by “[c]ities and counties”

against IDOT highway property. The answer is no. Drainage districts are not

cities, counties, or subdivisions of either. They are sui generis.

The second question is whether assessments against IDOT highway

property may be based in part on the reduced cost and hassle that motorists may

experience because drainage-system improvements lead to fewer flood-related

road closures. The answer is no. Drainage-district assessments should be based

on benefit to the property and, by extension, its owner. So, in the case of IDOT

highway property, the assessment should be based on the costs and effort that

the State will avoid if an improvement is completed.

I. Background.

A. Drainage District Principles. “Article I, section 18 of the Iowa

Constitution empowers the legislature to ‘provide for the organization of drainage

districts . . . .’ ” William & Mary Goche, LLC v. Kossuth Cnty. Bd. of Supervisors,

5 N.W.3d 650, 651–52 (Iowa 2024). “A drainage district is a special governmental

entity that manages water drainage in a particular area to enable more 4

productive uses of farmland.” Iowa N. Ry. v. Floyd Cnty. Bd. of Supervisors, 29

N.W.3d 307, 308 (Iowa 2025). Drainage districts only have those limited powers

that “the legislature grants them.” Bd. of Water Works Trs. v. Sac Cnty. Bd. of

Supervisors, 890 N.W.2d 50, 55 (Iowa 2017) (quoting Reed v. Muscatine Louisa

Drainage Dist. #13, 263 N.W.2d 548, 551 (Iowa 1978)).

The powers granted to drainage districts, as well as rules governing their

creation and governance, are found in Iowa Code chapter 468. Robinson v. Cent.

Iowa Power Coop., 21 N.W.3d 842, 850 (Iowa 2025); Chi. Cent. & Pac. R.R. v.

Calhoun Cnty. Bd. of Supervisors, 816 N.W.2d 367, 370 (Iowa 2012). Chapter 468

authorizes county boards of supervisors to establish drainage districts. Iowa

Code § 468.1. And, at least initially, those boards of supervisors manage the

districts. William & Mary Goche, LLC, 5 N.W.3d at 652; see also Iowa Code

§ 468.126(1). Later, “the district may be placed under the management of a board

of trustees.” William & Mary Goche, LLC, 5 N.W.3d at 652 (quoting Fisher v.

Dallas County, 369 N.W.2d 426, 428 (Iowa 1985)); see also Iowa Code § 468.500.

These trustees are “elected by the persons owning land in the district that has

been assessed for benefits.” Iowa Code § 468.500(1)(a).

Drainage districts construct drainage systems and assess the construction

costs “against those properties that benefit from the system.” Abbas v. Franklin

Cnty. Bd. of Supervisors, 16 N.W.3d 305, 308 (Iowa 2025). Those costs are to be

apportioned according to the benefits received by the property. See Union Pac.

R.R. v. Drainage Dist. 67 Bd. of Trs., 974 N.W.2d 78, 82–83 (Iowa 2022). The

greater the benefit that a tract of land receives, the heavier the cost that will be

assessed against the tract and, ultimately, paid by the tract’s owner. Id. at 83.

When the drainage system needs to be repaired or improved, “the board of

trustees may consider whether the existing assessments are equitable as a basis 5

for payment of the expense of the repair.” Id. at 82; see also Iowa Code

§ 468.65(1). If the board concludes that the existing assessment is “inequitable

in any particular,” the board “shall by resolution express such finding,” appoint

qualified commissioners, and order a reclassification. Iowa Code § 468.65(1). The

reclassification commission should consider what benefits “are attributable to or

enhanced by the . . . repair[] [or] improvement.” Id. § 468.65(1)(c). Ultimately, the

commission “shall fix the percentage of actual benefits and make an equitable

apportionment of the costs and expenses of such repairs[] [or] improvements.”

Id. § 468.67. Then, after notice and hearing, the board “may affirm, increase, or

diminish the” commission’s assigned “percentage and assessment of benefits

and apportionment of costs and expenses so as to make them just and

equitable.” Id. The resulting reclassification “when finally adopted shall remain

the basis for all future assessments unless revised” through another

reclassification. Id. § 468.65(2).

B. The Current Case. With this background in mind, we turn to the case

before us.
