Prior to the presentation of the final subdivision map for Board of Supervisors' approval, the subdivider shall file a preliminary soil report with the building inspection division of the Department of Community Development. The report shall be prepared by a civil engineer who is registered by the state of California, based upon adequate test borings or excavations in the subdivision. The preliminary soil report may be waived if the building inspection division determines that, due to the knowledge of such division as to the soil qualities of the subdivision, no preliminary analysis is necessary. The determination shall be in writing and shall be made part of the data accompanying the final map.
(SCC 574 § 2, 1983; SCC 1585 § 48, 2015)
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, a soil investigation of each lot in the subdivision shall be prepared by a civil engineer who is registered by the state of California. The soil investigation shall recommend corrective action which is likely to prevent structural damage to each dwelling proposed to be constructed on the expansive soil. The report shall be filed with the building inspection division.
(SCC 574 § 2, 1983)
The building inspection division shall approve the soil investigation if it determines that the recommended corrective action is likely to prevent structural damage to each dwelling to be constructed on each lot in the subdivision. Appeal from such determination shall be to the Board within ten calendar days. The board shall hear the appeal and make its decision within thirty 30 days, conditioned upon the incorporation of the approved recommended corrective action in the construction of each structure.
