The Iowa Court of Appeals has ruled against the Worth County Board of Supervisors in their appeal regarding the annexation of land into Drainage District No. 72 (DD72). The court's decision, filed on October 7, 2026, affects several landowners who opposed the annexation, highlighting the importance of proper drainage management in agricultural areas.

This case centers on a dispute involving multiple landowners, including David S. Mercer, Kimberly Mercer, Mervin C. Anderson, and others, who challenged the Board's decision to annex approximately 1,806 acres of land known as Upper Goose Lake into DD72. The ruling emphasizes the need for clear evidence of material benefits to landowners when considering such annexations.

The disagreement began after the Board hired an engineering firm to assess the need for repairs and potential annexation of the Upper Goose Lake area into DD72. The Board's engineer initially recommended annexation, stating that the land would benefit from existing drainage facilities. However, landowners presented objections, arguing that the land would not materially benefit from being annexed into the drainage district.

Following a public hearing on February 27, 2023, where objections were raised, the Board voted to proceed with the annexation. This decision prompted the landowners to appeal, arguing that the Board's actions were not supported by sufficient evidence. The case was brought before the Iowa District Court for Worth County, where the judge ruled in favor of the landowners.

In the ruling, the district court declined to consider several “amendment” reports submitted by the Board after the annexation vote. The court found these reports did not provide adequate justification for the annexation. The Board's engineer had failed to include critical information in the initial report, which led to the court's decision to disregard the amendment reports.

The court stated, "The amendments here include information available at the time of the Board’s decision that the Board’s engineer failed to initially include." This ruling underlines the importance of thorough and accurate reporting in decisions affecting land management.

Furthermore, the court determined that the Upper Goose Lake lands would not materially benefit from annexation into DD72. The Board argued that the land would gain increased drainage capacity, but the court found that the natural topography of the land would allow for adequate drainage without the need for annexation.

Judge Buller, writing for the court, noted, "To annex land into a drainage district there must be evidence the land will in all reasonable probability derive some special benefit from the improvement." This statement reinforces the legal requirement for demonstrating clear benefits before land can be annexed into a drainage district.

The court's ruling has significant implications for local landowners and drainage management in Iowa. It sets a precedent that emphasizes the need for substantial evidence of material benefits when considering annexation into drainage districts. This decision may also influence future disputes involving drainage management and land use in agricultural areas.

Moving forward, the Board of Supervisors has the option to appeal the ruling to a higher court. However, the court's decision stands as a reminder of the importance of transparency and thorough documentation in governmental decisions affecting landowners.
