310-GEOTECHNICAL AND GEOLOGICAL HAZARDS

This requirement is taken from section 15.18.090 of the City’s Municipal Code

310.1 Offsite Geotechnical and Geological Hazards. No certificate of occupancy or permit under this title shall be issued under the provisions of this chapter when the Building Official finds that the proposed work on, or change in use of, the site for which the permit is requested could activate or accelerate a geological or geotechnical hazard that could damage other property.

310.2 Geological and Geotechnical Hazards. Work requiring a certificate of occupancy or permit under this title is not permitted in an area determined by the Building Official to be subject to hazard from any variety of landsliding or settlement or slippage except as allowed by Sections 310.4 through 310.8. These hazards include, but are not limited to, loose debris, slopewash, and potential mudflows from natural or graded slopes.

310.3 Geological and Geotechnical Reports. The Building Official may require a geological or geotechnical report, or both, where, in the Building Official’s opinion, such reports are essential for the proper evaluation of the proposed work or use of the site. As part of this evaluation, the Building Official may require a site visit in order to evaluate the need for such reports. A fee for this site visit shall be collected at this time. A geological report shall be prepared by a Certified Engineering Geologist licensed by the State of California. A geotechnical report shall be prepared by a registered Civil Engineer qualified to perform this work. Every report shall contain a finding regarding the safety of the site, for the proposed structure or use against hazard from any variety landsliding or settlement or slippage and a finding regarding the effect the proposed building, grading, and/or construction and use of the site will have on the geological stability of the site and/or property outside the site. When both a geological and a geotechnical report are required for the evaluation of the safety of a building site, the two reports shall be coordinated before submission to the Building Official.

310.4 Safe Site. Subject to the conditions of subsection 310.1, a certificate of occupancy or permit under this title may be issued in the following cases:

A. When the applicant has submitted a report(s) required by Section 310.3 that contains sufficient information to satisfy the Building Official that all geological or geotechnical hazards will be eliminated prior to use or occupancy of the land or structure by modifications of topography, reduction of subsurface water, buttresses, or by other means or combination of means and that the proposed work on or use of the site will not adversely affect the subject property or neighboring properties.

B. When the applicant has submitted a report(s) required by Section 310.3 that contains sufficient information to satisfy the Building Official that the site is not subject to geological or geotechnical hazard.

C. Notwithstanding any provisions of this Subsection, the Building Official may, at his or her discretion, deny a permit for any building, structure or grading subject to a hazard of a geological nature which cannot be mitigated and may endanger the health or safety of the occupants, adjoining property, or the public.

310.5 Hazard Eliminated. A certificate of occupancy or permit under this title may be issued only if the reports required by Section 310.3 contain sufficient information to satisfy the Building Official that all geological or geotechnical hazards will be eliminated, prior to use or occupancy of the land or structure, by modification of topography, reduction of subsurface water, buttresses, or by other means or combination of means sufficient to provide a factor of safety of not less than 1.5.
