Storm Safety Advisory

Preparing for Upcoming Storms

The National Weather Service has informed us that another atmospheric river is expected to hit the Bay Area through the weekend, and has issued a Flood Watch for the entire area. This storm is anticipated to bring 1.5-4 inches of rain to the East Bay region between Thursday and Sunday. In comparison, the New Year's Eve storm dropped nearly 5 inches of rain in about 12 hours. While excessive runoff from melting snow is expected, the National Weather Service has stated that the greatest accumulation of rainfall will be in the mountains. The hydrologic outlook notes that creeks and rivers may rise by 25%, and there may be ponding in low-lying areas. 

Regular maintenance has been performed on Town-maintained creeks and drain inlets, but with the strength of the upcoming storm, we advise residents to prepare for potential flooding in low-lying areas. This safety advisory offers tips and suggestions for the community to stay safe during the expected heavy rainfall. 

The three main areas of concern are that the rain coupled with the increased winds are expected to generate flooding, downed trees, and loss of power.  Residents need to avoid any travel during the atmospheric river events

In addition to regular maintenance for Town-managed ditches, drains, and culverts, residents are encouraged to help in this effort as the storm approaches.  If there are small patches of leaves or debris blocking the storm drain along your street, clear the debris to allow storm water to flow through unobstructed into the storm water system.  

SANDBAG STATIONS: The Town has a self-fill sandbag station for community use. We are continuing to refill the station using vendors as sand is available.  We ask that everyone please limit themselves to 20 bags per household. The sandbag station is located at: 1000 Sherburne Hills Road, Danville

STANDING WATER AND FLOODING: If necessary, barricades will be used to close roads, and we ask the community to comply with closures.  Not only is there a risk of your vehicle stalling out and becoming stuck in the water, but those who drive around the barricades also push water up onto flooded yards and into the homes along the street and increase their risk of becoming stranded. Stranded drivers put an increased strain on first responders and divert them away from other incidents requiring life safety measures.. 

DRIVING TIP: If you hit standing water and begin to hydroplane, immediately take your foot off the gas pedal and let your vehicle slow until you regain control. When driving in heavy storm conditions, give yourself plenty of extra time to get to your destination and maintain a safe distance between yourself and the vehicle in front of you. If your windshield wipers are on, your headlights MUST be on as well.   Your best bet is to avoid driving all together during the upcoming storm.  

DOWNED POWER LINES: High winds are also expected. If you see downed power lines, stay at least 30 feet away and do not attempt to drive over them. Always assume they are energized and dangerous. Report downed lines to 911. 

FALLING TREES: Be wary of trees falling. Because of the extreme saturation of the ground, root structures will be weakened, and trees could come down in a strong wind. When out walking or driving, be aware of your surroundings and watch for trees that are leaning. Similarly, be cautious when walking under trees, as high winds can also bring limbs down. 

POWER OUTAGES: With heavy rain and strong winds in the forecast, it is possible that Danville could experience prolonged power outages. Residents are encouraged to make sure electronic devices are charged up tomorrow morning in the event of an outage. Outage information will be available for viewing on PG&E's outage map at When there is a power outage, signalized intersections will not work, and must be treated as stop signs.
