Benton County Ditch 9 repair draws questions over costs, notice and who pays

An engineering presentation and subsequent public hearing on the final repair order for Benton County Ditch 9 focused on field‑survey findings, bid results and whether affected landowners were properly notified and fairly assessed.

Engineer Joe presented results of a field survey covering roughly 5.5 miles of the ditch, saying crews measured channel‑bottom elevations, collected cross sections and probed through accumulated organic sediment to the original excavated bottom. He said inspectors found sediment buildup ranging “as little as a half a foot to 2 or more feet,” clogged culverts and at least one tree obstructing flow. Joe said three culverts were recommended for replacement and that survey and construction work identified a wetland impact of about 0.06 acre at an upstream location. "We did end up buying 0.06 — we had 0.06 acres of wetland impact," he said.

The engineer outlined cost estimates presented in the repair report and said the lowest construction bid, from a firm with recent county ditch experience, was $297,000 and that the contractor had met contract requirements. He also stated a final contract payment of $16,606 was to be made. The presentation referenced larger line items and contingencies in the repair report and an earlier mitigation/repair figure that staff described during the hearing as roughly $440,000; total project figures discussed in the presentation ranged across different slides and the presenter later said an overall figure of $496,000 was the out‑turn cost for redetermination, repair and wetland credit work.

At the hearing, many landowners said they either had not received clear notice of the full set of assessments or that the benefit allocation did not reflect the realities on their land. Several speakers said they had not seen the published legal notices in the Benton County News or had difficulty finding Ditch Authority minutes online. Frank Danielson said he reads the county newspaper weekly and "I have never ever seen a notice for any kind of a public hearing about a Ditch Authority meeting or an assessment meeting in the Benton County News." County staff responded that affidavits of mailing and of publication exist for the April 14 mailing and the May 2, 2023 hearing notice and that those documents are in county files.

A common question was why landowners on upstream or adjacent ditches — described in the presentations as Ditch 12 and Ditch 14 — were now receiving separate assessments tied to the work on Ditch 9. Staff explained the viewers' redetermination of benefits assigned outlet or contributor percentages so that a portion of each dollar spent on CD‑9 work was apportioned to CD‑14 and CD‑12 (staff cited roughly 26¢ from CD‑14 and 5¢ from CD‑12 for each dollar in an example). That viewers' allocation, plus a notification error the county said it discovered, prompted issuance of additional assessment letters for the affected ditches and a continuation of the hearing to allow proper notice.

Landowners raised affordability concerns. Tim Cole asked the authority to consider a lower interest rate and a longer payback — for example, 2.25% interest over 20 years — to make payments feasible. County staff responded that statute limits payback terms for repairs: repairs are typically limited to 10 years or 15 years depending on whether the assessment exceeds half of the total benefits for the ditch, and for this project the staff estimated total benefits at about $1.3 million and said the repair assessment was under 50% of benefits and therefore limited to a 10‑year repayment term.

Several speakers criticized the use of outside consultants and the perceived pace and cost of the ditch program, and urged the county to seek broader funding. Others asked for on‑site inspections to clarify how water moves across their property. County officials acknowledged the frustration and emphasized that the Ditch Authority must follow state ditch statute and viewers' procedures; staff said they will provide access to the affidavits of mailing and publication and will follow up on site visits and the separate CD‑14 hearing scheduled in June.

The hearing transcript records the presentation of findings, public comments and staff answers but does not record a roll‑call vote on the final payment. The engineer said the contractor met contract conditions and recommended a final payment of $16,606; the transcript does not show a formal motion and recorded vote on that payment at the time of the public comments.

The Ditch Authority said next steps include making the affidavits and assessment breakdowns available to property owners and scheduling site follow‑ups for disputed locations. Maintenance assessments and terms will be handled in a separate proceeding, the county said, and landowners will receive notice when that hearing is scheduled.

The continued public hearing on the final repair order for County Ditch 9 closed after staff committed to follow‑up on notice documentation, provide itemized assessment records on request, and proceed with the required statutory steps for any payments and maintenance proceedings.
