180 Mr. Swift explained that the conditions listed in Exhibit B relate to a modified plan that would take all of the houses off of the hill. Condition 9 refers to the supplemental environmental impact report to address those areas that the EIR said would be affected by the remedial grading. Jerry Dommer, 256 Sutter Street, San Francisco, Dommer & Byers Architects, explained that this project has been in process for approximately six years. It has come a long way in this process and finds itself in a gridlock of opinion between the City's consulting geologist and' the development's project geology team. The recent Planning Commission approval of 37 lots removed 17 lots, which are the nicest lots of this development. He introduced Mr. Makdessi who would explain how their team of geologists concluded that the ancient landslide was stable. Simon Makdessi, 4384 Indigo Drive, San Jose, Terrasearch, explained that between 1986 and 1990 there has been a number of investigations on the geological aspects of this project. In 1990 a consensus was reached among all of the geologists regarding certain geological landslide mechanisms of the project. The ancient landslide is at least 40,000 years in age. In 1992 there was additional investigation work which determined the stability of this landslide. He explained the types of tests and investigations carried out to make the conclusion that this ancient landslide is stable. Mr. Makdessi pointed out that the staff report indicated that the landslide had the potential to move 2 feet under earthquake conditions. He stated that there was no information as to where this conclusion had originated. Mr. Makdessi concluded that the applicant had gone out of his way to determine that this landslide was stable. Dr. Robert Pyke, 1076 Carol Lane #136, Lafayette, Registered Civil and Geotechnical Engineer, reviewed the Terrasearch report dated August 4 and October 12 and did not fully agree with the report dated August 4. He supported the opinion of the City's reviewing geologist that there were sufficient uncertainties in the calculations that had been done and believed it appropriate to do additional studies. The conclusions are not only the function of calculations, but are also functions of observations over a period of time as to the geologic history of the site. The calculations always introduce some element of uncertainty. There is an ancient landslide that moved down the slope and is presently stable. He concurred with the findings listed in the October 12 report. He did believe that this landslide is stable. He believed that there was no technical reasons produced to counter the conclusions of Terrasearch's October 12, 1992 report and no technical reasons why Council should not approve the 55-1ot development. Jerry Dommer concluded by asking for approval of the 55-1ot project. He asked that in the event that Council voted to approve the 37-1ot project that Council not place lots B and C into a 11/17/92 6
