NAPA (AP) — The earthquake that jarred California’s wine capital caused $1 billion in damage, Napa County officials estimated Monday as business owners mopped up high-end vintages that spilled from barrels and bottles and swept away broken glass in the rush to get the tourist hotspot back in shape for the summer’s final holiday weekend. With the dust still settling from Sunday’s magnitude-6.0 temblor centered near the city of Napa, government and tourism officials assessing its economic and structural impact encouraged visitors to keep flocking to the charming towns, tasting rooms, restaurants and spas that drive the Napa Valley economy. While cleanup will take time and broken water mains remained a problem, they said, the worst damage and disruption was confined to the city’s downtown, where a post office, library and a 141-room hotel were among 150 homes and buildings deemed unsafe to occupy.
