Valley Water flood preparedness amid El Niño concerns
Valley Water declared an El Niño state of emergency on October 7 to speed procurement for flood protection, and Mountain View is among cities sharing preparedness resources. A separate San Mateo County coastal report warns of possible high tides and storm-related flooding, but focuses on coastal impacts and does not establish a specific Mountain View threat. Residents can check local sandbag locations and use AlertSCC for emergency updates; the declaration is a preparedness step, not confirmation that severe storms or a wet winter are certain.
