Del Valle Dam Foundation Stability Analysis
NOE - Notice of Exemption
Project Geology will drill one hole outside the embankment of Del Valle Dam in order to collect data. Drilling will be conducted using a CME 75 or similar rig, and water cooling of the drill bit will be supplied by a 1,000 gallon water truck. Once the drilling has been completed, the hole will be grouted from the bottom of the hole to within two feet of the surface. The remaining two feet will be filled with native soils.
The State Water Project provides significant and important services to many Californians. This project is exempt because it involves routine maintenance activities. This project will not result in impacts to special status species or habitat. Because this activity can be implemented without any significant environmental impacts, the Categorical Exemption Class 1 will be used for CEQA compliance.
