When last winter’s atmospheric river storms pummeled farmland east of Lodi, a different “river” of water began flowing through the vineyards and down Acampo Road right toward an isolated neighborhood known informally as Cooper’s Corner. Storm drains were overwhelmed. Water backed up into people’s yards and, in some cases, their homes. Water climbed the steps of the Houston School near Acampo Road and Highway 99, and spilled into a convenience store across the street.
