Prior to issuing permits, a soils and/or geology report is usually required to be submitted to the Division for technical review by our geotechnical engineers and geologists.

Reports submitted to the Division typically address geotechnical engineering design as well geologic hazards, such as slope instability/earthquake induced landslides and liquefaction (Seismic Hazard Zones).

Areas near active faults, including those in the Alquist-Priolo Earthquake Fault Zones, require sufficient geologic investigation and coordination with the Division’s geologists. Various Information Bulletins provide additional information relative to requirements of the Grading Division.
