RIVERSIDE, Calif. (KABC) -- California Conservation Corps members who work to prevent problems during the rainy season had training days in the Inland Empire Thursday.
They were doing it to prepare for another winter storm set to soak the Southland Friday afternoon and into the overnight hours.
The group learned that if just one bag is out of place or set up improperly, the entire sandbag wall can come down in a big flood. The training day also included washwave protection, which are large plastic tarps that go over hillsides to prevent mudslides.
