Commission reviews drainage upsizing near US 30; staff to study agreement and costs
Summary
County engineer Brad outlined plans to upsize a failing tile near 300 East and US 30 to 36 inches for roughly 500 feet to address capacity concerns tied to nearby development; staff will assess whether a new or amended agreement with the drainage board is needed and provide refined cost estimates.
Brad (speaker S3) briefed the Redevelopment Commission on a proposed amendment to a previous drainage project addressing a low spot and replaced tile near 300 East and U.S. 30, across from Lincoln Point.
Brad said developers had changed assumptions about runoff and that the repaired tile should be upsized: “My recommendation would be to replace the existing 15 and 24 from racetrack up to where it becomes a 36, which is about 500 feet with a 36,” he said, noting that matching capacity with parallel pipes would not be sufficient.
He estimated the work’s incremental cost is “in the realm of, like, $10,000” and said there is remaining balance from the original project that could cover it, but staff must verify whether the original agreement remains valid or if a new agreement or amendment is required. Brad recommended staff (Andy) determine the proper procedure and, if bidding is required, follow applicable solicitation rules; he noted that the drainage board typically solicits three quotes for similar work.
Commission discussion covered whether the drainage board or the RDC would solicit quotes, potential effects of additional nearby development, and the option to map the low-lying parcel as flood-prone or consider acquisition to prevent inappropriate future development at the overflow collection point.
Why it matters: upsizing the tile aims to prevent overflow and erosion tied to new development at Lincoln Point and adjacent sites, reducing future flood and maintenance risk.
Next steps: staff will refine the cost estimate, verify agreement status with the drainage board, and return recommendations on contracting and funding to the commission.
