UPLOAD Geologic/Geotechnical Reports

The Seismic Hazards Mapping Act (Section 2697(a)) requires cities and counties to submit a copy of each approved geologic/geotechnical report, prepared as a result of the presence of a Seismic Hazard Zone, to the State Geologist within 30 days of its approval.  The California Geological Survey strongly encourages that these reports and associated documentation of approval be submitted in digital format (PDF, MS Word, etc.).
