A preliminary soils report, prepared by a civil engineer registered in this state, and based upon adequate test borings, shall be required prior to approval of any final tract map, except that:
The city council may waive the preliminary soils report if it finds sufficient data is available to determine that the soils qualities of the soils of the tentative tract are such that no analysis is necessary or the conditions of approval of a tentative map are likely to prevent structural damage to the structures to be constructed, and the conditions of approval are incorporated in the construction of each structure.
