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.

A. All new construction is prohibited on the parcels which are located entirely or partially within the boundary of Slide Mass C, except as provided in this chapter. The existing parcels located entirely or partially within Slide Mass C are identified in Section

A. The
Chief of Building and Safety may approve, or approve with conditions,
new construction on any portion of such affected parcels which is
located at least 25 feet outside of the boundary of Slide Mass C,

of a licensed engineering geologist, based upon adequate site investigations,
borings, soil samples, laboratory tests and a review of all record
data for the parcel and slide area, to the satisfaction of the Chief
of Building and Safety and in compliance with all other applicable
codes and regulations.
B. A preliminary
evaluation of the engineering geologist for the suitability of improvements
on such area shall be submitted for review by the Chief of Building
and Safety before the preparation of plans pursuant to this section.
The Chief of Building and Safety may employ expert peer review in
reaching a decision as to whether to accept or reject the findings
of the evaluation.

listed as being appropriate for reconstruction, may be reconstructed
by their owners in the manner consistent with the recommendations
contained with the 2009 Kenton Report, including, specifically, the
applicable construction recommendations contained in the Grover Hollinsworth
