A preliminary soils report, prepared by a civil engineer specializing in soil and foundation engineering who is registered in California, and based upon adequate test borings, shall be required for every subdivision for which a final map is required by this part.
(Ord. 2093, 1975)
The preliminary soils report may be waived if the Planning Director determines that due to the knowledge he has as to the qualities of the soils of the subdivision, no preliminary analysis is necessary.
(Ord. 2093, 1975; Ord. 2800, 1979; Ord. 2506, 1977)
If the preliminary soils report indicates the presence of critically expansive soils or other soils problems which, if not corrected, would lead to structural defects, or if the preliminary soils report indicates the presence of rocks or liquids containing deleterious chemicals which, if not corrected, could cause construction materials such as concrete, steel, and ductile or cast iron to corrode or deteriorate, more detailed soils investigation of each lot in the subdivision may be required prior to approval of the final map or parcel map. Such detailed soils investigation shall be done by a civil engineer, specializing in soils and foundation engineering registered in California, who shall recommend procedures or establish structural damage to each structure proposed to be constructed in the area where such soils problems exist.
(Ord. 2093, 1975; Ord. 4181 § 11, 1992)
The Board of Supervisors or the Planning Commission may approve the subdivision, or portion thereof, where such soils problems exist if it is determined that the recommended procedures or the use of the recommended structural design criteria are likely to prevent structural damage to each structure to be constructed, and as a condition to the issuance of any building permit, may require that said procedures or structural design criteria be incorporated in the design and construction of each structure.
