The project consists of geologic and underground utility location explorations. Geologic explorations consists of 13 Cone Penetrometer Test borings, 7 mud rotary borings, and 4 test pits. Underground utility location explorations include geophysical ground surveys and potholing with a vacuum knife.
The project is being conducted to collect data on any underground utilities and geologic/geophysical features within the Perris Dam Emergency Release Facility project area. There will be a qualified biological monitor on-site to ensure there are no impacts to native vegetation or sensitive wildlife species.
