FRESNO, Calif. (AP) — California officials approved a plan on Friday that recommends major investments in the state’s aging system of levees that protect people and farmland in the Central Valley, an area with one of the highest flood risks in the nation.

The plan, adopted by the Central Valley Flood Protection Board, calls for as much as $17 billion in repairs and new investments in the levees and other infrastructure, including $5 billion in bond funds already approved by state voters.
