A. A preliminary soils report, prepared by a civil engineer registered in this state and based upon test borings, shall be submitted to the city engineer or director of public works for every subdivision.

B. Preliminary soils reports may be waived by the city engineer or director of public works for subdivisions of four or less lots, providing he finds that no preliminary analysis is necessary because the city already has sufficient knowledge of the soil qualities of the land within the subdivision.

C. If the city has knowledge of, or the preliminary soils report indicates the presence of, critically expansive soils or other soils problems which, if not corrected, would lead to structural defects, a soils investigation of each lot in the subdivision may be required by the director of public works or city engineer. Such soils investigation shall be done by a civil engineer registered in this state, who shall recommend the corrective action which is likely to prevent structural damage to each structure proposed to be constructed in the area where the soils problem exists.

D. The advisory agency may approve the subdivision or portion thereof where the soils problems exist if it determines that the recommended action is likely to prevent structural damage to each structure to be constructed and the action is made a condition of the building permit.
