By reason of special geologic hazard, unstable soils condition, and lack of suitable support, new construction must be prohibited within the area known as the "Conejo Slide." A landslide that occurred in the vicinity of Conejo Road within the City of Santa Barbara revealed unstable conditions in the area depicted on the Map of the Conejo Slide Area adopted as part of this chapter. The area was the subject of a report (dated April, 1984) by Geotechnical Consultants, Inc. and has been under observation since. Three separate landslide masses were identified as being subject to special geologic hazard, designated as Slide Mass A, Slide Mass B, and Slide Mass C, all located within Slide Mass C on the Map of the Conejo Slide Area adopted as part of this chapter. The earth within the boundary of Slide Mass C is unstable; structures and other property on Slide Mass A, Slide Mass B, and Slide Mass C have been damaged because of that instability; and further damage to structures and property within the boundary of Slide Mass C is highly probable. Excessive groundwater has been identified as a major cause of instability. Septic tanks have contributed sewage effluent to that excessive groundwater. The provisions of this chapter are necessary to maintain the public safety and welfare and to protect against hazardous local geologic and soils conditions.
