Document Description
The purpose of the San Pablo Dam Seismic Upgrade Project is to improve the embankment and foundation soils downstream of the Pablo Dam to withstand shaking generated by the maximum credible earthquake on the Hayward-Roger Creek fault without significant strength loss, to limit permanent deformation or settlement at the dam crest to acceptable levels, and to prevent damage to the outlet works, thereby ensuring that the risk of flooding to downstream communities after a seismic event is significantly minimized. The proposed project involves using large, multiple auger equipment to inject and mix cement grout into portions of the dam foundation material, and the construction of a larger buttress fill on the downstream face of the dam.
