Public Information:

Storm updates, reservoir and creek levels, areas of concern, and sandbag information is being disseminated to the community through news media inquiries, Facebook, Twitter , Nextdoor, the Water District's blog at www.valleywaternews.org and the Water District's web site at www.valleywater.org

Residents are encouraged to make sure their storm drain inlets are clear of leaves and other blockages so that rainwater can flow into the storm drain system rather than backing up and causing street flooding.

Residents who spot downed trees or other creek blockages are encouraged to report that information to the Water District's watershed hotline (408) 630-2378 during business hours or use the Access Valley Water online reporting system at www.valleywater.org

Residents are advised that sandbags are most effective when used to prevent flooding from one-foot-or-less of water from entering a home or business through doorways and garage door openings; and are cautioned to take only 20 to 30 bags per vehicle.

Sandbag sites run by the water district, cities, or the county are operated on the honor system as a flood protection service to residents. The bags are not meant for use in construction or gardening activities.

Residents are reminded not to drive through flooded waters. If floodwaters rise around your car, abandon the car and move to higher ground. A foot of water will cause many vehicles to float. Two feet of rushing water can carry away most vehicles, including SUVs and pick-ups.

Next Scheduled Update: Thursday, November 2, 2017 unless conditions change.
