URS Corporation has teamed up with the California Department of Water Resources in the Urban Levee Evaluation Project (ULE) and Non-Urban Levee Evaluation Project (NULE) provide geotechnical evaluations of 1,454 miles of levees in both urban and rural areas.
The ULE will assess 450 miles of levees in the San Joaquin and Sacramento basins of the Central Valley that protect densely urban areas from flooding. The purpose of this evaluation is to determine whether the levees comply with geotechnical criteria put forward by the US Army Corps of Engineers. If the levees do not meet this criteria, remediation measures will be identified.
The goal for all California levees is to protect development from a 200-year flood level. URS will speed this project by using new technology and solutions.
NULE will also see URS evaluating the geotechnical strength of 1,604 miles of state and federal rural levees in the Sacramento River basin.These non-urban levees will also provide 200-year storm protection, but for less than 10,000 people.
This major project coincides with one of the worst drought on record. Perhaps since creek and lake waters will have drastically decreased, now is the ideal time to be reevaluating and restoring levees that will keep California residents safe once the rains do return.
