 On January 1, 1886, Orvil Township was formed from portions of Hohokus Township and Washington Township.The "Boroughitis" phenomenon that swept through Bergen County, in which 26 boroughs were formed in the county in 1894 alone, hit Orvil Township particularly hard, resulting in the formation of five new boroughs created from the nascent township, including Montvale and Woodcliff (now Woodcliff Lake) on August 31, 1894, Allendale on November 10, 1894, Saddle River on November 20, 1894, and Upper Saddle River formed on November 22, 1894.On April 7, 1919, a council of citizens voted to incorporate as the borough of "Waldwick", from the remaining portions of Orvil Township.
