The City's water facilities, as well as Zone 7's, have been constructed in accordance with the applicable building codes to minimize potential damage during an earthquake. Additionally, approximately 85% of the City's water infrastructure has been earthquake reinforced, and no area within the service area is solely dependent on non-earthquake reinforced infrastructure. The City has multiple turnouts from Zone 7; so, if one is damaged during an earthquake, the City can use the remaining turnouts to continue receiving water supply from Zone 7. Furthermore, the pipelines were built in a looped arterial design to ensure there is more than one route for water flow. 5 COMMUNICATION PROTOCOLS In the event of a water shortage, the City must inform its customers, the public and interested parties, and local, regional, and state entities. This section addresses communication protocols for foreseeable and unforeseeable events. 5.1 Communication for Foreseeable Events For foreseeable conditions, the City initiates communication through the AWSDA decision process and City Council stage actions. Messaging includes the declared shortage stage and the required demand reduction actions from Table 5. If a water shortage emergency is anticipated, City staff coordinate interdepartmentally, with the region's water service providers, and with Alameda County for the possible proclamation of a local emergency. In a duly noticed meeting, the City Council receives presentation of the current or predicted shortage as determined by the current AWSDA.The City Council determines if a water shortage emergency condition exists and the degree of the emergency, while considering the shortage response actions triggered or anticipated to be triggered by the shortage level.As necessary,the City Council acts on the water shortage emergency declaration and the associated shortage stage and response actions.
