Operations Committee backs redesigned 4th Street profile, recommends board consider concrete alternate
Summary
The committee recommended the board approve Cochran’s redesigned profile for 4th Street to improve truck access, including a bid alternate to concrete the first block; engineer estimates cited about $226,534 in additional work and an estimated city share of roughly $45,000 under an 80/20 grant split.
The Operations Committee on Dec. 12 voted to recommend that the full board approve a redesign of the 4th Street and Osage intersection intended to improve turning radii and the slope for tractor-trailer traffic, and to include an alternate bid to put the first block in concrete.
Mister Bergen, who presented the proposal, said Cochran’s original design focused on resurfacing and standard curb-and-gutter work but did not adequately address truck turning or the approach grade. He said engineer cost estimates put the STP construction budget at about $1,123,902 and the current design cost at roughly $894,000, leaving about $229,000 available under the grant. He said a reprofile and widening would add approximately $226,534 in engineer-estimated costs; with an 80/20 grant split, Bergen said the city’s estimated share would be about $45,000.
Bergen also described an alternate to concrete the full approach (Osage through the lumber yard) rather than perform a mill-and-overlay on the asphalt; he said that option would add about $527,000 to the project and could be advanced as an alternate bid to see where contractor pricing lands.
Committee members asked technical questions about the diagram and retaining-wall depiction and emphasized safety benefits of the wider profile for large trucks. A committee member moved to recommend the redesigned profile (curb, gutter, sidewalk with the reprofile) and the alternate concrete option to the full board; Alderman Stewart seconded and the committee approved the recommendation by voice vote.
Staff said Cochran is already working on design details and that, if property easements and survey work proceed as planned, the item will be placed on the full board agenda for final authorization.
