of other emergency operations and equipment. They have monthly inspections of all of their <br />infrastructure, including the reservoirs and dams, and have a system in place for immediate <br />inspection of all facilities following a local earthquake. <br />While Chabot Dam has been routinely strengthened over the years, and it has been <br />engineered to withstand a 7.2 earthquake on the Hayward Fault (the Maximum Credible <br />Earthquake [MCE] seismologists anticipate could occur on this fault) and they are confident <br />that the dam would remain stable with this intensity of an event, a recent study has <br />determined that there could be some cracking near the dam's abutments and those require <br />some seismic strengthening. EBMUD is undertaking a full CEQA impact report for the <br />project. The CEQA process is expected to be completed by Spring 2012, design of the fix <br />would be done by mid -2013, and constriction would be done 2013-2014. <br />Mayor Cassidy asked City staff and EBMUD to plan a presentation to the full City Council <br />as early as possible. He also asked that EBMUD and the City look toward planning an <br />emergency drill that would allow both agencies to exercise response to a dam failure <br />scenario. <br />Mr. Frew reported that EBMUD works closely with Alameda County OES and the East Bay <br />Regional Park District, which provides their police and fire services. Plans exist to have <br />dams inspected immediately after an earthquake and to notify local public safety agencies <br />immediately if any sign of failure is detected. Assistant Chief Shnepp from ACFD <br />commented that they have trained on a number of occasions with EBMUD and are confident <br />that reliable communications systems are in place to notify San Leandro Police and Alameda <br />County Fire if an emergency exists, and that alternate water resources have been identified <br />for firefighting should EBMUD's supply lines fail. <br />Questions from Disaster Council members included an inquiry about the availability of <br />drinking water should EBMUD's distribution system fail. Mr. Few reported that EBMUD <br />works with the state and a consortium of other water agencies to provide potable water <br />sources in the event of a system failure. They have reciprocal agreements with other agencies <br />in California and Nevada to provide services wherever needed in the event of a disaster. <br />Another question came up regarding how the community would be notified of the need to <br />evacuate or take other actions due to a dam failure. Kathy Ornelas reported that a number of <br />notification tools are in place. The Alerting and Warning Siren System will notify the <br />community that an emergency situation exists. People have been educated over the years <br />that the sirens mean to check Radio 1610, the City's website and cable channel 15 for <br />emergency instructions. Also, Code Red will be used to send out telephone messages with <br />alerts and instructions. <br />The community can find more information about EBMUD's facilities and their emergency <br />operations, plus emergency preparedness recommendations, on their website — <br />www.ebmud.com. <br />Public Comments: <br />Mike Katz commented that the MCE on the Hayward fault should be re-evaluated in light of <br />this year's earthquake and tsunami in Japan. <br />2 <br />
