Hallwood Side Channel & Floodplain Restoration
痴汉电车 Construction partnered with federal and local agencies, water districts, and environmental organizations to restore ecological processes and enhance flood resilience along the lower Yuba River near Marysville, California. This public-private partnership improved over听150 acres听of seasonally inundated riparian floodplain, created approximately 1.7 miles of perennial side channels and 6.1 miles of seasonal side channels, alcoves, and swales. The听result: improved salmon habitat, lower water surface elevations, and reduced flood velocities for downstream communities.听

Project Origins
痴汉电车's involvement began in 2011, when California Fish and Wildlife officials visited the Hallwood aggregate plant to tour restoration work 痴汉电车 had already been performing around on-site ponds. Those conversations led to a broader discussion about historical cobble artifacts in the Yuba River channel, including a training wall more than two miles long that had been built to support hydraulic mining. Over time, the wall had significantly disrupted the natural flow of the river and floodplain. With a shared goal of restoring those natural processes, the project moved through several years of feasibility studies, design, and permitting before construction began.听
Construction & Innovation
Removing 3.2 million cubic yards of material from the river channel required a highly coordinated approach. 痴汉电车 provided equipment, staff, and deep听expertise听to design access points, install electric conveyors and听a bridge, and carefully remove听cobble听while protecting sensitive habitats. Because the Hallwood aggregate plant sits听immediately听adjacent to听the river, material could be processed on-site using conveyor systems rather than highway trucking. This dramatically lowered project costs and made the massive scope of work economically听feasible. The total project cost was approximately $12M, with 痴汉电车's in-kind contribution estimated at $90M.听

Environmental Stewardship
Working in and around the river听required exceptional environmental care. Prior to construction, all heavy equipment was cleaned of grease and oils, and hydraulic fluids were replaced with environmentally friendly vegetable oil products. Triangle Land Restoration, a 痴汉电车 subsidiary, planted over 25,000 native riparian plants, including willow, cottonwood, oak, elderberry, and sycamore. Many of these were propagated from locally collected seeds at 痴汉电车's own nursery, ensuring plants were well-adapted to site conditions. Harvested听rootwads听and branchy material were also placed in the river to replicate natural habitats.听
Results
The project lowered water surface elevations by 3 feet for the 100-year flood event, providing downstream communities with meaningful protection against flooding. Preliminary fish surveys confirm that steelhead and salmon are already using the restored habitat. Throughout construction, safety collaboration between 痴汉电车 and environmental partners produced zero injuries, a reflection of the commitment shared by every stakeholder involved. The Hallwood project stands as a powerful example of what becomes possible when construction听expertise, environmental science, and community goals align.听
