City Council Approves Change Order for Colorado Boulevard Sewer Upsize Project

The city council held a special meeting to reconsider and approve change order number two for the Colorado Boulevard sewer upsize phase three project. This change order increases the project cost by $15,040.28 and revises the final completion date to July 13th, 2026. The need for the change order arose from the unexpected discovery of rock gabions, which are used for scour protection around bridge ends, during excavation. These gabions were not indicated on the original bridge plans from 1978 and were buried, preventing their identification during the initial planning. The contractor encountered these during instructed digging, and the additional work is necessary to protect the bridge infrastructure. The proposed cost was reviewed by consultant HDR and compared to state DOT bid pricing, falling within a reasonable range, leading to staff and consultant recommendation for approval.
