Document Description
DWR needs to conduct some exploratory work to help fill in data gaps needed to both confirm the bedrock depth and the geotechnical parameters of the shallow soils near the Lake Perris Dam. The exploratory work will help determine the strength and weathering of the rock. The exploration holes can help reduce the unknown chance of bedrock formations being higher than expected in the area.
