Geologic hazard evaluations are incorporated into geologic studies and may also be performed as a site-specific objective. Geologic hazard evaluations range from preliminary assessments to detailed analysis of hazards and design of mitigation measures.

Geologic hazard evaluations address:

• Faulting and seismic hazards, including ground shaking, ground rupture, and liquefaction potential
• Landslide, mudflow, debris flow, and rockfall potential
• Groundwater conditions
• Potential for flooding
• Erosion potential
• Compressible peat and organic soil deposits
• Expansive soils
