Olancha Emergency Flood Repair
Document Type
NOE - Notice of Exemption
Document Description
March 2023 storm events destroyed multiple drainage systems within the active construction limits of the Olancha Cartago 4-lane project. Catch slopes, subgrade, and base were severely eroded throughout project. Also caused by the same storm event, 3 existing drainage systems on existing US 395 were damaged and over topped resulting in flooding of US 395. Los Angeles Department of Water and Power met with Caltrans District 9 management to voice concerns about major flooding potential which could likely flood and wash out US 395 in Olancha. The culverts across highway may not be adequate for anticipated excessive spring run-off, which could potentially result in further damage and a closure of US 395 for several weeks. Flooding of US 395 is imminent unless these drainage systems are replaced with larger capacity systems
