Engineer flags Branch 60 tile failures; board orders preclassification for Joint Drainage District 2
Summary
An engineering review found multiple blowouts and undersized historic tile on Branch 60 of Joint Drainage District 2. The engineer estimated a repair at about $460,000 and an upsized improvement at about $560,000; the joint board voted to proceed with a preclassification so landowners can see likely assessment costs.
At an informational meeting for Joint Drainage District 2 on Jan. 14, the district engineer reported four recent tile blowouts on the lower end of Branch 60 and said the historic clay tile in that stretch is likely degraded and undersized for modern drainage demands.
Why it matters: the Branch 60 tile system drains cropland and repeated breaks are already disrupting roads and fields; the board must decide whether to perform localized repairs or pursue a larger improvement that upgrades pipe capacity and reduces the need for repeated fixes.
Engineering findings and cost estimates: the engineer said the lower reach showed repeated breaks and that a camera inspection would better document internal pipe condition; he estimated a targeted repair of approximately 5,000 feet at about $460,000 (roughly $667 per acre averaged over the affected acreage) and an improvement to a higher drainage standard (0.5 inches/day) at about $560,000. He explained that much of the cost is in excavation and trenching and that upsizing certain pipe segments would substantially increase capacity for a relatively modest additional cost.
Board decision: after questions from landowners and supervisors, the joint board voted to proceed with a preclassification for the affected reach so landowners can see parcel-level assessment estimates for both a repair and an improvement option. The board discussed, but did not order immediately, televising the tile; staff said camera inspection (estimated $5,000–$7,000) is an option if the board decides to fund that follow-up.
Landowner comment: landowner James Sabol attended and described washed-out gravel roads after flooding and said he supported an improvement if it would prevent repeated future failures; he said he is willing to consider supporting an improvement but noted he is a landowner (not operator) and that long payback periods may be a concern.
Next steps: staff will prepare preclassification numbers for both the repair and the improvement scenarios, draft a potential repair/improvement report and, if a petition for improvement is filed, prepare an improvement report and formal hearing. The board directed staff to contact the landowner who initially submitted the repair request and to proceed with preclassification work.
