Book excerpt: This study was performed for the purpose of determining the final geotechnical recommendations for levee repairs in the Mid-Valley study area. The Mid-Valley study area is one of five phases in the Sacramento River Flood Control System Evaluation. The Mid-Valley Study Area includes approximately 350 miles of flood control levees as shown in Figure 1. In general, the levees within the study area have performed well. There have been relatively few cases of levee slumping and foundation piping and only isolated reports of complete levee failure. However, some of the reaches which have experienced instability or foundation piping in the past are considered a potential threat to the integrity of the system. This basis of design focuses primarily on the reported problem sites that were identified in the December 1991 Initial Appraisal Report (ref. I, Appendix B). Following further evaluation, structural remediation is recommended at several sites. The conclusions and recommendations are based on review of geotechnical reports (references 1 through 4), review of office files of problem areas, site inspections, interviews with local representatives, additional explorations, laboratory testing, and seepage and stability analyses at various sites. Twenty-nine sites identified in this study are considered the
