County staff outlines bridge, culvert and paving plans; tests new asphalt patch product
Summary
Lake County staff reviewed asset-management work on county buildings and parks, detailed bridge and culvert projects funded by downstream mining-related NRD funds, and described testing of a Texas-supplied asphalt product (Brock Asphalt) with a three-year warranty for pothole repairs.
Lake County staff used the work session to summarize county asset-management priorities for buildings and parks, planned culvert and bridge projects, paving priorities and a pilot of a new asphalt patch product.
Michael Irwin, a county staff member, said the county is developing an asset-management plan for county buildings and intends to compile a list of parks and maintenance responsibilities shared with the city. He noted swaps in maintenance responsibilities for specific properties and listed parks discussed during the meeting.
Irwin described a set of bridge and culvert projects funded by mining-related NRD funds and administered by a grant administrator the county identified as Arwick. Projects include culvert replacements near trailheads and the County Road 9 bridge near the Lakeville Junction parking lot on the north side of Turquoise Lake, and a bridge across Tennessee Creek. He said those projects aim to reduce drainage blockages in the Arkansas drainage and address major drainages and gulches on the east side of town.
On paving, Irwin said the county is considering paving County Road 11 from Colorado 300 out to where it splits, because that section receives heavy traffic and is in poor condition. He said the county secured some paving work this summer and has options for funding next year.
Irwin also described a pilot for a new asphalt product from Brock Asphalt, which he said is a limestone product with embedded asphalt that bonds under pressure. He said the supplier offers a three-year warranty and that the county will test the material for pothole repairs and other road patches. Irwin provided a price example for a delivery tote and noted the material is sourced from Texas.
Why it matters: planned bridge and culvert work addresses flood drainage and trailhead access; paving decisions affect public safety and vehicle travel; the pilot asphalt product could change short-term repair costs and durability of patching.
Background and next steps: staff said culvert and bridge engineering remains in progress, some materials may be ordered as projects advance, and the county will test the Brock Asphalt product on local roads and evaluate cost and durability before broader use.
