Vice Chairperson Maas advised that since she believes Commissioner Sullivan would like to be /""" present for the discussion regarding Item 7.a., "Draft Compact for a Sustainable Bay Area," she is suggesting that the Commission hear Ms. Grant's presentation and continue the Commission's discussion on the item until the July 11 meeting.

Final approval of the lane:uae:e in certain mitie:ation measures in the Final Supplemental Environmental Impact Report for Oak Tree Farm - Phase 3 Michael Roush advised that staff has modified a number of the mitigation measures in the Final SEIR in accordance with the Planning Commission's comments made during the June 13 meeting. He further advised that staff discussed with Mr. Alan Kropp, who is present this evening, the two issues concerning the geological matters. Mr. Roush reported that he also discussed the mitigation measure concerning the biological assessment with Commissioner Sullivan, and that he was satisfied that the modification addressed his concerns. Mr. Roush advised that he feels that the mitigation measures as presented addressed the concerns raised by Commissioner Sullivan and Commissioner Arkin at the June 13 meeting. He noted that Mr. Kropp and Mr. Grubstick are available to answer any technical questions regarding the revised mitigation measures. r-- Mr. Grubstick responded to Commissioner Harvey's inquiry regarding the groundwater issue, noting that the assumptions that were made in establishing the groundwater surface elevation were very conservative and they were brought up to a level that is much higher than what would be expected. He further noted that the requirement that two additional winters be monitored has been included in the measures. Commissioner Roberts provided information on the rainfall measurements during the last eight years, noting that there have been several heavy rainfall years that would have affected the reading. She noted that there are other conditions that can change the underground water level, including a slight earthquake. Commissioner Arkin stated that because his area of expertise is not geology, he has difficulty with the issue related to the earthquake analysis. He advised that he understands what staff has attempted to do in accordance with Mr. Kropp's recommendation, however he is still uncomfortable with this matter. He noted that he wished that he could provide better feedback to staff regarding his concerns, but since he is unable to do so, he will agree with the modified measure. Mr. Grubstick advised that staffhas looked at a way of establishing some additional data, in that Commissioner Arkin had indicated at the last meeting that he was uncomfortable with having a single data point on which to rely. Commissioner Arkin advised that he feels the geological information for a project is the most difficult to understand and he would like to be able to attend a workshop that would help clarify this information. Mr. Roush responded that he would inquire as to whether that type of workshop could be offered at a future League of California Cities' conference. Commissioner Harvey asked ifthe Commission wants to maintain the two-year rainfall-sampling requirement. Commissioner Roberts advised that she feels it is important to keep it at two years r- June 27, 2001 Page 2 PLANNING COMMISSION MINUTES
