Background
After a long-running dispute over maintenance of a private drainage ditch connected to Drainage District No. 72’s facilities, the Worth County Board of Supervisors hired an engineering firm to assess repairs and recommend action. The firm recommended annexing about 1,806 acres known as Upper Goose Lake into DD72, concluding that the parcels materially benefited because excess surface and subsurface water discharged through DD72 facilities.
Landowners objected before and at the public hearing. After the Board voted to annex the land in March 2023, the landowners retained an engineer who concluded that, except for roughly 46 acres, the land would not materially benefit from DD72 because it would naturally drain without the private ditch’s connection to district facilities. On appeal to the district court, the Board offered four post-annexation “amendment” reports from its engineer. The district court excluded those reports and reversed the annexation decision.
The Court’s Holding
The Iowa Court of Appeals affirmed. It held that the district court properly declined to consider the Board engineer’s amendment reports. The reports included information available when the original report was prepared, rather than proper supplementation, and were created after the Board had already voted to annex the land.
Considering the record de novo without those reports, the court agreed that the engineering and annexation reports did not sufficiently establish a material benefit to the Upper Goose Lake property. Where the topography naturally drains surface water, an owner must receive a benefit beyond merely having an outlet for that water. The district court permissibly credited the landowners’ expert testimony that the property was separate from the DD72 marsh and would naturally drain without the district connection.
Key Takeaways
- Post-decision reports cannot be used to cure deficiencies in the engineer’s report considered during the annexation process.
- Drainage-district annexation requires evidence that the affected land will probably receive a special, material benefit.
- Natural drainage alone does not establish material benefit from district facilities.
Why It Matters
The decision enforces the statutory safeguards governing drainage-district annexations: landowners must receive notice of the engineer’s findings before the Board acts, and the Board’s decision must rest on an adequate contemporaneous record.
For drainage districts and local boards, generalized statements that water drains through district facilities may be insufficient when the land naturally drains. A report must identify a concrete material benefit supporting annexation.
