<br /> <br />2021 Multijurisdictional Local Hazard Mitigation Plan <br /> <br />2020 to Present Drought <br />The U.S. Department of Agriculture declared a drought disaster that include San Mateo County on April 21, 2020. <br />April 2021 was the third driest April in the past 127 years (National Integrated Drought Information System, <br />2021). As of June 2021, San Mateo County was at the D3—Extreme Drought level, putting the county at risk for <br />wildfire on a year-round basis (National Integrated Drought Information System, 2021). On April 15, 2021, the <br />SFPUC sent wholesale customers a letter on water supply availability estimates for 2021 and current hydrological <br />conditions. The letter stated the following conditions and projections at that time (San Francisco Public Utilities <br />Commission, 2021): <br /> The Hetch Hetchy watershed was experiencing very dry conditions <br /> The April 1 snow course index was about 60 percent of the median historical snowpack level. <br /> San Francisco needed about 554,000 acre-feet to fill the entire water system by July 1, 2021. <br /> Snowmelt forecasts indicated that the Hetch Hetchy reservoir would fill during the year. <br /> The water bank was not expected to fill. <br /> <br />2012 to 2017 Drought <br />California’s last drought set several records for the state. The period from 2012 to 2014 ranked as the driest three <br />consecutive years for statewide precipitation. Calendar year 2014 set new records for statewide average <br />temperatures and for low water allocations from the State Water Project. Calendar year 2013 set minimum annual <br />precipitation records for many communities. Detailed executive orders and regulations addressed water <br />conservation and management. The statewide drought emergency was lifted in April 2017. <br /> <br />This drought had significant effects on the southern coastline of San Mateo County because many community <br />members in this area rely on creeks and wells that have stopped flowing. Rural communities in the County faced <br />stringent limitations on bathing, using toilets, and washing items, and many ranches and farms in the area saw <br />significant economic downturns. Urban parts of the San Francisco Bay area experienced limitations in order to <br />conserve water, but not to the extent imposed on rural community members (SFGate 2014). <br /> <br />During this drought, San Mateo County and its cities implemented initiatives to maintain the quantity and quality <br />of water resources in the County: <br /> San Mateo Countywide Water Pollution Program <br /> Groundwater Protection Program <br /> Land Use and Septic Wells Program <br /> Recreational Water Quality Program <br /> Small Drinking Water Systems Program <br /> Municipal Facilities Water Conservation Efforts. <br /> <br />2007 to 2009 Drought <br />The state proclaimed a statewide drought emergency on June 4, 2008, after spring 2008 was the driest spring on <br />record. On February 27, 2009, the state proclaimed a state of emergency for the entire state as severe drought <br />continued. The largest court-ordered water restriction in state history (at the time) was imposed. <br /> <br /> <br /> <br />9-8
