G'ornmissioner Roberts noted that regardless of whether Stoneridge went through, El Charro going through would help that intersection. Mr. Swift believed that Stoneridge was more important to that intersection_ Mr. Walsh noted that they wished to get some direction from the Planning Commission as they proceeded with their application_ They had worked on the current application since May, 2002, and had attended several Planning Commission and Housing Commission meetings. He noted that their main concern was with regard to any moratorium surrounding the East Pleasanton Study Area. They would like their application to proceed and stand alone. Commissioner Roberts noted that if this project were separated from the East Side Study, the Commission would have more questions for Mr. Walsh_ Bil] Berger, VP Operational Services, Hansen Aggregates West, 136 Victory Circle, San Ramon, wished to clarify the questions regarding the lakes_ Lakes H and I were part of the chain of lakes concept, as designated by Zone 7. He noted that the small, skinny "lake" on the west side of Lake I was put in by Hanson as Lake I was being excavated; they pumped water to the west relief face of Lake I, which was the percolation face from the working pit, in order to dewatcr it_ A discussion of the drainage, percolation, and possible soil erosion ensued. Mr. Berger advised that there had been concern about water levels, and noted that Cope Lake was a sealed basin which did not percolate, and was used for silt. In response to Commission concerns about flooding, he noted that the lakes could not exceed the 350 foot level. Currently, Cope Lake was at the 343- to 345-foot level. As part of the agreement, Zone 7 would take Lakes H and I, and will go out to Mohr Avenue and take that property. Hanson would not have any access to Lakes H and I, and Cope Lake was not part of the Chain of Lakes. He noted that they would give Zone 7 an easeirient around the lake for maintenance, but they do not have ownership up to the water level on Cope Lake because that was part of a separate agreement. In response to an inquiry by Chairperson Arkin, Mr. Berger confirmed that access roads did go down to the water level. In response to an inquiry by Commissioner Roberts, Mr. Berger noted that in 39 years, they had not had any problems with people accessing Lake I from Martin Road. Greg Sousa, Kie-Wit Construction, 3200 8a 3300 Busch Road, noted that he was the plant supervisor of the casting yards. He described the site used by Kie-Wit, and noted that they manufactured precast, prestressed piling in the 35 acre square in the center. He noted that they have manufactured the piling for 30 years, and Hanson was their source £or aggregate. They currently have an agreement with Vulcan for aggregate.
