Culprits are soil cracking that allows water seepage, soil-strength reduction, land subsidence and erosion, all of which NWNL observed on its California Spotlight expeditions in 2014 and 2015. Fifty-five percent of California's levee systems are now in danger of failing … Continue reading Drought and Flooding increases CA Levees risk of failure
