Santa Clara County Issues New Evacuation Warning to Watershed Areas of the Uvas Reservoir, Pacheco Pass River Basin and HWY 101 and Bolsa Road


Heavy Rains, Strong Winds, Flooding, Falling Trees, Power Outages, and Shallow Mudslides Are All Possible Dangers

SANTA CLARA COUNTY, CALIF. – The County of Santa Clara has issued evacuation warnings to community members residing in the watershed areas of the Uvas Reservoir, Pacheco Pass River Basin and HWY 101 and Bolsa Rod due to the weather conditions and potential risks of flooding to the general public and property. 

The prolonged stretch of winter storms has brought heavy rain and high winds to the region. These unusual rain levels have created impacts that include soils near or at their saturation point, creeks, streams, and rivers reaching or exceeding flood stage, and low-lying area experiencing flooding, including road crossings. There is also an increased risk of rocks and sediments dislodging from the hillsides. Driving will be challenging during periods of gusty winds, especially for high-profile vehicles, including emergency response vehicles.
