Supervisors discuss riprap and ditch siltation after washed-out culvert
Summary
Supervisors described using riprap and fence-post barriers to stop erosion and debated whether filter cloth or riprap would hold; members noted significant sediment buildup in a ditch that has run onto the road and discussed the cost of a washed-out culvert repair.
A supervisor described a private fix — close-set fence posts filled with rocks — that has prevented erosion for about a decade and recommended using riprap at a problem ditch that has deposited sediment on the roadway.
"Use riprap and let it filter through the riprap," Committee member (S1) said, describing the approach they’d seen work on a former farm site. Committee members discussed whether filter cloth or riprap would hold under the current flow; Committee member (S3) warned that high flows can bypass such measures and suggested finding another approach if needed.
Speakers reported dozens of truckloads of dirt and corn stalks in the ditch and cited specific washed-out culverts that required substantial fill, pipe and labor costs. The meeting did not record a formal decision on a repair schedule or funding; members noted that culvert repairs have required hauling fill from several miles away and cited example costs for pipe, fittings and mobilization.
Next steps: The transcript shows members agreeing to measure right-of-way and to arrange follow-up site inspection and measurement, but no formal motion or funding authorization for immediate culvert replacement was recorded in the meeting.
