Scott County ditch authority continues Ditch 4 hearing to Dec. 16 amid transfer vs. abandonment debate; approves Ditch 10 maintenance contract

The Scott County Ditch Board on Nov. 18 heard an extended briefing on County Ditch 4including ownership, benefit rolls, sediment sources and contractor bidsand voted to continue the hearing on abandonment to Dec. 16 at 8:00 a.m.

County counsel and SWCD staff summarized a multi-month process stemming from a landowner request to abandon County Ditch 4 (also known as Credit River in parts of the corridor). Staff said the City of Credit River had previously offered to petition to accept a transfer but had conditioned acceptance on specific rehabilitation work. SWCD presented a parcel/benefit analysis (about 1,014.21 benefit acres; 252 taxpayers and split assessments for 10 common-area parcels) and four rehabilitation bid segments that together totaled $141,125. Staff modeled several assessment scenarios ($50k, $75k, $100k and $150k) and showed how per-parcel costs would rise for residential, commercial and agricultural property as project totals increase; staff also noted the maintenance fund balance is negative roughly $12,208.

Technical staff (Scott Soil & Water) explained sediment sources: (1) Credit River entering the ditch and delivering sediment, (2) in-channel sloughing of PD soils, (3) bank failures caused by tree loss and natural processes, and (4) a significant eroding ravine outside the ditch corridor. Commissioners debated whether it would be fair to place a large assessment burden on the current, relatively small group of benefited owners when much of the sediment is generated off those owners' land or benefits a larger municipal population. Counsel advised the board that transfer requires a city petition and that abandonment would not prevent other entities (city, watershed or state grants) from addressing the river in other ways.

After discussion, the board voted to continue the hearing for further consideration and directed staff to engage City of Credit River elected officials; the board set a continuation for Dec. 16 at 8:00 a.m.

Separately, staff presented a post-construction report for County Ditch 10 that identified local areas needing additional erosion and buffer work. The SWCD said it solicited bids and received one full bid from KA Witt Construction for $59,750 to perform bank-slough/erosion maintenance and sediment removal. The board voted to authorize entering the contract with KA Witt and confirmed SWCD will supervise contractor performance.

Why it matters: the board must weigh whether to retain the drainage authority with assessments on a limited benefit roll or pursue abandonment/transfer that would shift responsibilities and funding options; the Ditch 10 contract addresses immediate maintenance needs for a separate drainage system.

Outcome: CD4 hearing continued to Dec. 16 at 8:00 AM; KA Witt contract for CD10 approved by voice vote.
