New and intriguing information identified by the U.S. Geological Survey (USGS) and its partners has been published in the Journal of Geophysical Research. For the first time, researchers have identified large-scale surface uplift and expansion in the San Gabriel Valley directly caused by groundwater recharge, due to near-record rainfall in 2004-2005. The San Gabriel Valley rose almost 2 inches (47 mm) in less than four months, and the margins of the basin were pushed outward by almost half an inch (10 mm). The expansion was five times larger than slight oscillations observed since 1998.

However a forthcoming report by Seth Stein and published by the American Geological Society contends the hazard has been overstated. His colleagues at the USGS and the University of Memphis disagree.
An article by the New Orleans Times-Picayune reports that some of the sheet piles used in the levee along the 17th Street Canal are only 4.5-ft below sea level. The US Army Corps of Engineers say they have done "the most extensive technical analysis ever performed" on the drainage canal, but at least one person is not finding comfort in that claim.
