A preliminary soil report based on adequate test borings or excavations and prepared by a civil engineer who is registered by the state of California shall be filed with the tentative map, unless the city engineer determines that based on his knowledge of the soil qualities of the subdivision, no preliminary analysis is necessary.
If the preliminary soil report indicates the presence of critically expansive soils or other soil problems which if not corrected would lead to structural defects, the city engineer may require that a soil investigation be prepared by a civil engineer who is registered by the state. The soil investigation shall include a report which recommends corrective action likely to prevent structural damage to dwellings, roads, or other public works to be constructed.
A subdivision, or portion thereof, may be approved where such soil problems exist if it is determined that the recommended corrective action is likely to prevent structural damage to each structure to be constructed. Any building permit issued for such structures may be conditioned upon incorporation of the recommended corrective action in the construction of each structure.
Nothing contained in this section shall be deemed to limit the authority of the building official to require geologic, soils, and engineering data and mitigation measures pursuant to Section 18.88.150 of this code.
