摘要

To improve California flood safety, reduce the risk of catastrophic flooding and loss of life, and to comply with the state legislature mandate that urban communities (more than 10,000 people) achieve a 200-year flood level of protection by 2025, the California Department of Water Resources (DWR) is undertaking unprecedented efforts to evaluate urban levees in the Sacramento and San Joaquin River valleys and Delta.rnDWR's Urban Levee Geotechnical Evaluations (ULE) Program is performing field exploration, testing, and analysis of 420 miles of state and federal levees protecting highly-populated urban areas in greater Sacramento, Stockton/Lathrop, and Marysville/Yuba City. The overall purpose of the ULE Program is to evaluate state and federal urban project levees and appurtenant non-project levees and determine whether they meet defined geotechnical criteria. The ULE Program will also, when required, identify remedial measure(s) to meet those criteria and bring these urban levees to a 200-year flood level of protection. The $70 million program uses cutting-edge technology and innovative solutions to facilitate expedited levee evaluations.
