River Vale explores a historically rich community that has been known over the years as the Overkill Neighborhood, Harrington Township, Washington Township, and the borough of Eastwood. One of the first settled areas of the Kakiat Patent, River Vale was the scene of the Baylor Massacre, New Jersey's bloodiest skirmish of the Revolutionary War. The area's fine farmland enabled some of Bergen County's earliest settlers to flourish. Strong streams provided power for the mills and the famed Collignon chair factory.

By the 1920s, a change came over the township. Its proximity to New York City made River Vale's land more valuable for recreation than for farming, and the township became known for its summer charms, golf courses, and ice arena. Visitors arriving in bus caravans traveled from urban areas to enjoy the pleasures of Herrmann's Grove, and fishermen flocked on opening day to angle for trout in the clear waters of the Hackensack River and the Pascack Brook. It was this very appeal that led to tremendous change as River Vale became one of North Jersey's attractive bedroom communities.
