ANTIOCH -- Attention all green thumbs and volunteers who don't necessarily mind a little mud.

Contra Costa officials and Friends of the Marsh Creek Watershed will be planting close to 1,000 native plants and trees 9 a.m. to noon Saturday at the Upper Sand Creek Basin Wetland Restoration Project Celebration and Volunteer Day.

The basin is at 6600 Deer Valley Road, south of Kaiser Permanente and Dozier Libbey Medical High School.

The Contra Costa Flood Control District recently created a 62-acre, bathtub-like detention basin at the southeast tip of Antioch. The $10 million project expanded the basin by eight times its old size to meet the region's stormwater collection needs and prevent floods.

As part of the project, county officials grew acorns, California sage and other native plant species at a nursery at the county offices in Martinez to restore 10 acres by the area's creek. The basin site had become degraded over the years because of cattle grazing and farming, officials said.

Aside from the handful of days a year where it will be needed to collect water, the basin will one day be turned into a 40-acre sports park.
