Study Finds Sacramento Levees Inadequate

The article reports on findings from the Natomas Levee Evaluation Report, which looked at levees along the north bank of the American River, the east bank of the Sacramento River and the south bank of the Natomas Cross Canal, in northern California. The report finds that the levees in the basin, known as the Natomas Basin, might not provide protection against 100-year flooding. Various shortcomings of levee structures could cause them to lose their certification from the U.S. Army Corps of Engineers, which in turn could cause flood insurance costs to rise. The article gives a history of how the Basin was formed during land reclamation and development efforts in the early part of the 20th Century and its connection to other flood control systems in the region. It also includes the Natomas project, which is intended to correct some problems by raising the levees' freeboard and reinforcing levees with slurry walls and riprap and plantings. New procedures may have to be used because of the unique constraints posed by proximity of houses to the project.
