Until a little more than a decade ago, this area was productive farmland, used for growing crops like tomatoes, alfalfa, melons and almonds. Now it’s set to be California’s next state park after a restoration project spearheaded by River Partners converted the ranch into rewilded riverside habitat. As climate change has doubled the likelihood of flooding in California, and is projected to increase runoff from storms by as much as 200 to 400 percent, this restored floodplain is proving to be a promising approach.
