- Document Description
- The selected plan proposes approx 340 acres of intertidal marsh restoration at Big Break via direct placement of 1,000,000 cy of material from annual O&M dredging over an estimated 10-year period and is both the Selected Plan and the Environmentally Preferred Alternative. Dredged material would come from O&M activities in the SF Bay to Stockton DWSC between approx station points 400+00 and 850+00. Dredged material would be directly pumped to the restoration site, rather than typical land-based dredged material placement sites. Approx 340 acres of open water habitat would be restored to intertidal marsh habitat, with approx 90 acres planted with aquatic vegetation. The remaining 245 acres would be underwater channels and shallow habitat for aquatic fauna species. In addition, the 50 acre remnant levee along the northern edge of Big Break would be treated for invasive plant species and would be planted with native riparian species.
