Delta Cross Channel Radial Gate Rehabilitation

$1M flood‑control rehabilitation completed ahead of schedule on the Sacramento River— delivered where prior attempts had failed.


This project was completed by Daniel Olson during his tenure as owner of Extreme Coatings, Inc. The leadership, judgment, and execution demonstrated on this project inform the work performed today at Stobie Construction & Supply—particularly on complex water, wastewater, and industrial infrastructure projects where schedule, safety, and durability matter most.

The Challenge

The project required rehabilitating two 60’ × 30’ radial flood control gates over an active, navigable river within a strictly limited outage window that allowed no schedule extensions. Two previous contractors had attempted the work and were unable to complete it on time, leaving large portions of steel unprotected and severely corroded.

Before

Advanced corrosion, failed coating systems, and exposed steel.

During

Engineered access, full containment, and accelerated execution.

After

Fully rehabilitated gates with long‑term corrosion protection restored.

The Solution

Rather than approaching the work as a standard coating project, the team treated it as a complex infrastructure rehabilitation requiring engineered solutions, constructability planning, and close coordination with the Bureau of Reclamation.
