Summary
Wapello County engineering staff recommended awarding County Project 90–115 to the low bidder, Norris Asphalt, citing recycling of existing asphalt and an overlay to extend pavement life; supervisors authorized the county engineer to sign project documents and discussed letting and staging timelines.
The Wapello County Board of Supervisors authorized the county engineer to sign documents to proceed with Iowa DOT County Project 90–115 after engineering staff recommended awarding the job to low bidder Norris Asphalt.
County engineering staff described the project as applying recycled asphalt as a support layer with an overlay on top, a method intended to minimize reflection cracking and prolong overlay life. The presentation said the low bid came in near the county’s estimate and that awarding the contract would accelerate procurement and scheduling.
Board members asked technical and scheduling questions about an Old Highway 34 railroad crossing and the timeline for work on 87th Street; the county engineer said final plans should be ready for internal review this week and that the letting is targeted for late February, with some additional compaction work required where grading will occur near the railroad. The engineer said the 87th Street improvements are in the county’s five-year plan and will be a multi-year project involving pipe work, widening and eventual overlay.
Supervisors approved the authorization by voice vote. The county will proceed with final plan review and prepare for the planned letting in late February.
