Frequently Asked Questions

Do I need to submit this project for CGS review?
A. See DSA IR A-4.13.
This Interpretation of Regulations melds the building code (especially §1803A) along with the laws and regulations
establishing seismic hazard zones.

How do I submit the project?
A. Instructions are available here.
Note that we now prefer electronic versions of the geohazard and geotechnical reports!

How long will CGS take?
A. Approximately 6 weeks. Review time may be increased during peak times when numerous submittals are received.

To ensure timely reviews, submit the reports to CGS about 2 months prior to construction document submittal to DSA.
The construction documents may change as CGS is reviewing the reports, but the site plan, proposed building
locations, and foundation system must remain unchanged, in order to ensure DSA can utilize the CGS review. In
addition, the Site Data Report from the design professional in responsible charge (CBC §1603A.2) submitted to CGS
must be the same as that submitted to DSA.

What is CGS looking for?
A. Compliance with the current building code, and adequate characterization of any geologic hazards that might affect
the proposed structure. Depending on the approach of the geologic consulting firm, the relevant reports may be
called geotechnical, geohazard, engineering geology, or seismic reports. Therefore, all these should be submitted to

See CGS Note 48 for further guidance.

How will CGS respond?
A. CGS will prepare a memorandum documenting our review comments. It will be forwarded to the School District (as
designated on the Work Order), and copied to the geologic consultants, the project architect, and the DSA Regional

If additional information is requested by CGS, responses from the geologic consultant may be uploaded
to the box. CGS will review these additional documents for existing projects as quickly as possible after they are
received. DSA will not provide final construction document approval until all CGS comments are satisfactorily
addressed and CGS issues a final concurrence memorandum.

How can I check the status of my project?
A. email Margaret Hyland ( or call (916-324-7324). Provide the CGS project
number, if you have it, or else the name of the school and the city.

We do not have an online equivalent to “DSA Tracker.”

Can I pay for expedited review?
A. No. CGS generally considers projects in the order that a complete submittal package is received. If we are made
aware of funding deadlines or other genuine schedule requirements, we will consider those needs by shifting available
staff on a project by project basis.

Special projects
• For sites within Alquist-Priolo Earthquake Fault Zones (or local equivalents), fault investigations should be performed
well in advance of building design. CGS should have the opportunity to review any fault trenches in the field. These
investigations may be submitted to CGS in advance of campus development. Contact Jennifer Thornburg at CGS to

Seismic Mitigation Program/School facility Program, Proposition 1D.
A geologic hazard report is likely not required to demonstrate eligibility for funding under the OPSC/DSA Seismic
Mitigation Program (refer to DSA Procedure 08-03). Geologic hazard reports and CGS review are required in Phase 1
(Eligibility Verification) only if faulting, liquefaction or landslide creates the potential for catastrophic collapse of the
structure. If eligibility for funding is based on the hazard presented by faulting, liquefaction or landslide, then submit
the project for our review as directed above. In addition, clearly identify the project as “Seismic Mitigation Program” in
the Scope of Work field on the Application form so that CGS can expedite our review of the project.

The consulting Engineering Geologist or Geotechnical Engineer is encouraged to review Appendix B of DSA Procedure
08-03, and to contact Jennifer Thornburg prior to embarking on the field investigation for any project that expects to
demonstrate eligibility on the basis of a geologic hazard.
