Kossuth County trustees approve reclassification of Drainage District No.4 laterals 40 and 42, adopt assessment schedules

Kossuth County trustees voted on June 1 to approve reclassification schedules for Drainage District No. 4 laterals 40 and 42, adopting assessments tied to project costs of $1,410,000 for lateral 40 and $230,000 for lateral 42.

The approvals followed formal public hearings during which a county staff member, identified in the record as Tyler, explained the reclassification process and the data used to compute benefit units and assessment percentages. "What percent class actually is is your benefit relative to the highest benefit," Tyler said, describing how each parcel's units of benefit are compared to the highest unit to produce a percent class that factors into the assessment schedule.

Why it matters: reclassification changes how the cost of completed improvements is apportioned among landowners in the drainage district. The trustee decisions set the schedules that determine each parcel's share of the outstanding project cost and associated interest, which trustees said were calculated through October of this year.

At the hearings Tyler described the five factors used to apportion benefits: area drained, the amount of land that drains to the facility, wetness and soil characteristics, proximity to the facility, and land-use/runoff characteristics. He said the calculations use elevation data from the 2020 LAR run and soil classifications from USGS surveys; that data is processed at square-meter resolution to derive flow paths and per-parcel units of benefit. Tyler also displayed digital elevation model (DEM) maps and flow-path catchments to show how water moves through each lateral and how parcels were assigned weighted averages for wetness and proximity.

The board took voice or roll-call votes to approve the measures. For the reclassification of DD4 lateral 40 the motion to approve carried on a roll-call recorded in the transcript as Wctor, Garmin, H and Nath voting "yes." The transcript similarly records approval for DD4 lateral 42 with the same set of recorded affirmative votes; the motions were carried.

Before the hearings the board approved three routine drainage repair requests (items 39–41), identified as being in Kyle's district, after a motion to authorize supervisors to handle the requests. That motion was moved and seconded and recorded as carried.

Trustees raised a follow-up issue about the damages maps: a trustee said a corner of a quarter-section appeared omitted from the damage report. Tyler said he would "look into that and work with Tammy's office" to confirm whether the parcel was included and to correct the record if needed.

The board discussed scheduling and process details: members agreed to add the reclassification to the assessments schedule for this fall and to have county staff (Courtney) meet with trustees the following week to review materials. Trustees also set a date to take an updated board photograph before membership changes and adjourned the meeting at about 10:10 a.m.

Votes at a glance - Repair requests (items 39–41): Motion carried (mover: Waxter; second: Garmin; voice votes recorded as affirmative). - DD4 lateral 40 reclassification: Approved (motion carried; roll call recorded as Wctor, Garmin, H, Nath — recorded as unanimous in the transcript). - DD4 lateral 42 reclassification: Approved (motion carried; roll call recorded as Wctor, Garmin, H, Nath — recorded as unanimous in the transcript).

What was not resolved: trustees requested confirmation about an apparent omission in a damage map; staff committed to follow up with Tammy's office. The transcript does not specify whether any assessment amounts will change as a result of that query.
