The Riverpark Neighborhood is bounded on the west by South Jefferson Street, on the south by the City of Napa limit line, on the east by the Napa River and on the north by West Imola Avenue A large portion of the neighborhood is a gated water-front community called the Napa Yacht Club. Many homes in the Riverpark Neighborhood are geared toward the Napa River with views or direct access to the water. It was originally part of the famous Spreckels Stockfarm, a one thousand acre ranch in south Napa. The Stockfarm was famous for several reasons, one of which it was where Seabiscuit was sired. The ranch was sold to the Sheveland Family and then eventually sold. The majority is now the South Wetlands Opportunity Area, which is part of the Napa River Flood Control Project. A small part is the Sheveland Ranch Neighborhood and the Riverpark Neighborhood.
