PROJECT PROFILES
SACRAMENTO LEVEE EVALUATIONS
LEVEE STABILITY TESTING
SACRAMENTO, CA
Gregg Drilling & Testing, Inc. (Gregg) is excited about joining the team chosen to investigate the hundreds of miles of levees in the Sacramento Delta. Following Hurricane Katrina in New Orleans, the importance of levee stability was brought to the forefront. The California Department of Water Resources has developed a strategy to investigate the California levee system and mitigate the risk of flooding.
Since December 2006, Gregg has been drilling borings and conducting Cone Penetration Testing (CPT) to aid in the evaluation of the stability of the levees near Sacramento. The drilling has consisted of hollow stem auger through the levee (approx. 30 feet) and then mud rotary drilling with coring to depths up to 140 feet. Gregg has completed over 100 borings to date totaling over 11,000 feet.
In addition to drilling Gregg has been heavily involved conducting almost 140 CPT soundings and 12,000 feet of testing. As the project is being conducted in phases, there will surely be more to come.
