The City of Palo Alto has activated its Emergency Operations Center to respond to any storm-related or other emergency events. We and our neighboring agencies are monitoring water levels in local creeks and waterways, especially the San Francisquito Creek.
The National Weather Service (NWS) is forecasting two-to-three inches of rain for the San Francisquito Creek (SFC) basin over the next 24 hours with the height of the storm arriving early to mid-afternoon Thursday. The SFC is not expected to go above flood stage, however debris accumulating at West Bayshore Road may present some unpredictable problems.
West Bayshore Road may be closed at the creek while staff work to clear debris. At this point, due to uncertainty about the amount and depth of debris that has collected in and around the bridge at West Bayshore Road and under Highway 101, staff cannot accurately predict water behavior in the creek at that location.
Multiple agencies are coordinating to mitigate flood risks and remove debris in an effort to improve water flow under the bridge and freeway. As conditions change, we will provide updates as appropriate.
The peak flow on SFC is expected to be 2100 cubic feet per second (cfs) to 2500 cfs today. At the height of Tuesday’s storm, the peak discharge was 4820 cfs at the USGS stream gauge. That’s the sixth largest flow measured on San Francisquito Creek since the gauge was installed in 1930.
