Section J104 Permit Application and Submittals
A geotechnical report prepared by a registered design professional shall be provided. The report shall contain at least the following:
- The nature and distribution of existing soils.
- Conclusions and recommendations for grading procedures.
- Soil design criteria for any structures or embankments required to accomplish the proposed grading.
- Where necessary, slope stability studies, and recommendations and conclusions regarding site geology.
Exception: A geotechnical report is not required where the building official determines that the nature of the work applied for is such that a report is not necessary.
For sites with mapped maximum considered earthquake spectral response accelerations at short periods (Ss) greater than 0.5g as determined by Section 1613, a study of the liquefaction potential of the site shall be provided and the recommendations incorporated in the plans.
Exception: A liquefaction study is not required where the building official determines from established local data that the liquefaction potential is low.
