discussed and felt that the people would have responded appropriately to provide the water necessary to maintain the flow of water within the Arroyo and protect the habitat. He felt it was possible to negotiate with the Hansen/Kaiser quarry to allow for continuous flow of water. He pointed out that 80% of that water would go into the groundwater basin for recharge, so there would not be a loss of water to the region. He also had concerns about the Sycamore Grove area and the impact of water discharge. But he wanted to find some way to mm on the pumps from the quarry to release a minimal flow to the Arroyo to maintain the life in the habitat. He referred to an aerial photograph of the area and described a dark ribbon of vegetation the starts at Shadow Cliffs Regional Park and goes through the City of Pleasanton. That is the Arroyo del Valle and it is a heavily vegetated area teeming with life and not the typical arroyo that goes dry on a seasonal basis. It has had continuous water flow for over thirty years with few exceptions. If you look to the east of Shadow Cliffs toward the Del Valle Reservoir, you can see a truly dry an'oyo bed with few trees and limited vegetation. Obviously that would be dry in summer. What Pleasanton has is a unique habitat through an urbanized area and is a major part of the city's stream and trail system with agreements for access to it. He acknowledged the prior cooperation with Zone 7 and did not want to discredit its efforts. He wanted to be creative and find a way to preserve this habitat in the heart of the City of Pleasanton. It is the only arroyo that does not go through a trapezoidal channel. He was not suggesting that Council have a full debate about this since that would occur at the LAFCo meeting. He asked for support to take the matter to LAFCo and for his efforts to preserve the arroyo and to work with the Zone to find solutions. He did not suggest pumping water from the groundwater basin, but rather felt some kind of solution could be found with the quarry operators. Ms. Michelotti referred to the memo from Randy Lum recommending the staffto continue to work with Zone 7 and the California Fish and Game Department for development of a long range plan for the arroyo, rather than for the city to step in and try to immediately alleviate the situation. Ms. McKeehan indicated the memo from Mr. Lam reflected his initial reaction to the issue and referred to the City using its own pumps to put water into the arroyo at a cost of about $10,000 per month. She believed his thought process was to identify the options available and expense. The greater concern was the long term implications of that action and the fact that the City would be stepping into the role of long term purveyor of water. He did not have the opportunity of talking about the Hansen quarry option. It seems to be a reasonable idea to explore. Staff contacted a member of the Hansen staff and he indicated this would be reviewed. One of the ponds that could have been used is now out of operation and the water level is too low. The second pond is low because it is supplying Shadow Cliffs. However, he was willing to investigate this situation to find a solution that could work. Ms. Michelotti would like to explore these alternatives and get some comment from Zone 7. She was concerned about a larger agency dictating what shall happen. She liked the Hansen option but wanted more information before she could support the action the Mayor is requesting. Ms. Dennis felt there were two approaches: go to LAFCo or not. The Mayor believes the community could support either financial or conservation measures. We could discuss these options at public hearings and proceed from there. She was not clear on what LAFCo would do Pleasanton City Council Special Meeting Minutes 13 07/09/02
