California’s Drift Away from Levees Continues

After more than a century of building levees higher to hold back its rivers, California took another step Friday toward a flood-control policy that aims to give raging rivers more room to spread out instead. The plan, adopted by the flood-control board for the Central Valley, covers a 500-mile swath from Mount Shasta to Bakersfield that includes the state’s two largest rivers and the United States’ richest agricultural region. It emphasizes flood plains, wetlands and river bypasses as well as levees. The plan is especially important for Stockton, which sits at the bottom of the San Joaquin River watershed.
