Wright County trustees say DD 36 Lateral C repair exceeded estimate; landowners to be assessed

Wright County drainage trustees met Jan. 20 to inform landowners that a repair on Drainage District 36, Lateral C, has exceeded the original contractor estimate and will be billed to the district's assessed landowners.

County drainage administrator Courtney Morris told trustees the total recorded cost as of Dec. 30, 2024, was $83,912.50, and that the contractor estimated remaining dozer work and 200 tons of riprap would bring the construction total to about $96,187.50, with seeding estimated separately at $23,400. A landowner later suggested the total project could approach roughly $125,000 once remaining work and contingencies are included.

The informational meeting was called after work began under an initial estimate of $48,700. County staff said early site conditions — prior "dip outs," sandy soils and unstable banks — required reshaping the ditch rather than a simple bottom "dip out," which increased the scope and cost. Dan Henniger of Henniger Construction explained the contractor left the ditch reshaped and placed riprap because prior dip-outs had created near-vertical banks that would slough again.

Under Iowa Code section 468.126, trustees may authorize repairs costing up to $50,000 without an engineer's report and without a formal landowners hearing. County staff and trustees discussed whether to obtain a post-construction engineer's report (estimated by trustees to cost $20,000—2,000). Trustees expressed that ordering an engineer's report now would impose additional costs on landowners for work that is largely complete. After discussion, trustees indicated consensus not to commission an engineer's report at this stage.

Trustees and staff emphasized that the proper procedures'including earlier notification to landowners and, when appropriate, obtaining an engineer's report before exceeding the $50,000 threshold'did not occur in this case. Chairman Rick Rasmussen apologized for the communication breakdown and said the informational meeting was intended to explain the work and next steps.

Landowners at the meeting raised concerns about siltation, crop losses and erosion from disturbed soil. One landowner asked about reimbursement for lost yield; staff said there is an existing damage-claims process under the drainage statutes, but claims are limited to work within the drainage easement and must meet code timelines and documentation requirements. Staff also discussed options to reduce future siltation, including voluntary filter strips along banks; trustees said adoption of such measures would be landowner decisions.

Courtney Morris said drone footage documenting conditions before and after the repair is posted on the county website under the drainage tab and that landowners may request photos or video by contacting the auditor's office. Staff also said the county will mail a final letter to landowners with the project's concluded costs and that assessments will reflect the district's total work, not just the single lateral repair, which means a parcel's assessment could include multiple projects if they were billed to the same tracks.

Trustees explained assessments may be spread over multiple years if a parcel's share exceeds the county's per-track threshold; trustees said typical repayment spreads are five or 10 years and that interest on payment plans is 6 percent. Trustees reiterated that, going forward, projects with bids in the upper $40,000 range should prompt early landowner notification and closer monitoring so decisions about engineer reports and hearings can occur before work progresses beyond the $50,000 threshold.

The meeting also included routine drainage business: trustees approved postage for the informational notice and signed two drainage repair invoices presented at the meeting (details in the 'Votes at a glance' summary below).
