While Mount Arlington is now mostly a suburban residential community, it was once a thriving resort community. In the era before the world wars and the advent of air travel, it was a welcome respite for the residents of nearby New York City and Newark.
Every summer, thousands would arrive by train at Landing Station, and then travel by water taxi across Lake Hopatcong to the area's many large resort hotels to escape the city heat and enjoy the famous "Mount Arlington breeze" which always cooled the summer evenings. There was also a major amusement park, Bertrand Island, which featured a world-famous carousel and roller coaster, which operated until the park was closed in 1983.[21]
Mount Arlington was incorporated as a borough by an act of the New Jersey Legislature on November 3, 1890, from portions of Roxbury Township, based on the results of a referendum held two days earlier. Additional territory was acquired from Roxbury Township on July 25, 1891, on May 31, 1893, and on May 31, 1894.[22][23] The borough is named for Henry Bennet, 1st Earl of Arlington.[24]
In March 2014, members of the public petitioned the New Jersey Department of Community Affairs to form the Roxbury Mount Arlington Study Commission to consider a possible consolidation of Mount Arlington and the neighboring municipality of Roxbury Township. In March 2015, the commission was formed with five members and two alternates from each municipality. If the commission votes to recommend a merger, the decision would have to be ratified by a referendum of the voters in each community.[25]
