Upper Sand Creek Basin Restoration Project
The USCB was a $10 million flood protection and habitat restoration project constructed in 2013 in Antioch, CA. The first phase of the Upper Sand Creek Basin was constructed in 1995 and has been expanded periodically since. The 2013 project expanded the basin to its ultimate footprint, connected the basin to Sand Creek, and addressed a number of critical needs in the watershed. Major project benefits include:
The USCB is the second largest basin in the Marsh Creek flood protection system (second only to the Marsh Creek Reservoir). The USCB provides 900 acre feet of storage, enough to contain a 100-year storm without spilling. This significantly reduces the flood risk for Antioch, Brentwood, and Oakley residents living downstream along Sand Creek and Marsh Creek.
Prior to the project, Sand Creek through the basin site was degraded and offered poor habitat. An important component of the project was the reconstruction and restoration of 3600 linear feet of Sand Creek as well as the construction of 10 acres of wetlands. The creek and basin was re-vegetated with native plants such as cottonwoods, buckeyes, native roses, oaks and other plants that were salvaged from the project site before the start of construction. The restoration also included the planting of 2500 willows that were harvested from other nearby sources. The willows help provide shade for the reconstructed Sand Creek running through the basin.
The District frequently partners with local cities or park districts to provide trails, parks, and public access on District facilities. For the Upper Sand Creek Basin Restoration Project, the District partnered with the City of Antioch on a future sports park. The basin was specifically designed to accommodate roadways, parking and level areas needed for the park. The current design of the sports park includes soccer and baseball fields, tennis courts, parking, and a children's playground. Basins such as USCB are excellent for this type of joint use because the area needed for floodwater storage is infrequently used. During sunny days, the large, flat and dry bottom of the basin can be used for other purposes, such as recreation.
Like it or not, there is significant trash that enters the basin through the local storm drain system.
The District designed an innovative trash capture system that will intercept and capture trash to prevent it from flowing into the restored creek and further downstream in our local waterways.
