Mayor Antonio Villaraigosa. Measure R is expected to generate $40 billion over 30 years. The measure detailed specific rail and highway projects that will be undertaken, including the Purple Line subway on the Westside and the Expo Line, a light rail project backed by Yaroslavsky that begins in Downtown Los Angeles and will end in Santa Monica when completed in 2017. The supervisor was also an early proponent of easing Westside traffic by converting Pico and Olympic Boulevards into complementary one-way thoroughfares. Health care In 2002, Yaroslavsky authored a ballot initiative to raise $168 million annually in an effort to avert the potential collapse of Los Angeles County's vast emergency and trauma-care network, which was threatened by a deep health-care budget deficit. Measure B passed with a surprising 73 percent of the vote, marking the first time since the 1978 passage of tax-slashing Proposition 13 that county voters had approved a direct tax on their property. As a result, the county was able to avoid the possible closure of two public hospitals while keeping emergency and trauma-care services afloat. Yaroslavsky, a former smoker, also has been acknowledged for playing a key role in the county's anti-tobacco efforts. In 1996, he successfully pressed the county to sue six tobacco companies to recover hundreds of millions of dollars in health-care costs from smoking-related illnesses. He accused the companies of specifically marketing to poor people, immigrants and teenagers who turn to county hospitals and clinics for treatment. Four years later, as part of a statewide settlement of tobacco litigation, the county received a $79 million payment, the first to be made annually for 25 years. In all, Los Angeles County was expected to receive nearly $3 billion as result of the litigation. In 2001, Yaroslavsky was diagnosed with Type 2 diabetes. Although a longtime daily runner, he immediately changed his diet and lifestyle, reducing his weight from 215 pounds to 185 in 2008. Yaroslavsky said the diagnosis led to his successful sponsorship of an ordinance that now requires all fast-food outlets in unincorporated Los Angeles County areas to post calorie counts on their menus. Yaroslavsky also is credited with bringing health care to a largely working-class Latino neighborhood in the northeastern San Fernando Valley by providing services through an innovative clinic built on the campus of the local Sun Valley Middle School. The clinic serves an area where many residents are uninsured, living
