Loch Arbour is a village in Monmouth County, New Jersey, United States. As of the 2010 United States Census, the village's population was 194, reflecting a decline of 86 (-30.7%) from the 280 counted in the 2000 Census, which had in turn declined by 100 (-26.3%) from the 380 counted in the 1990 Census. As of 2010, Loch Arbour was the third-smallest municipality in New Jersey in terms of area (behind Shrewsbury Township and East Newark) and was the fifth-smallest municipality by population in the state of New Jersey.
Loch Arbour was formed as a Village by an Act of the New Jersey Legislature on April 23, 1957, from portions of Ocean Township, based on the results of a referendum held that same day. Loch Arbour's formation was driven by efforts to build condominiums in the area. Residents who sought to prevent the development led the secession effort, taking with them the last portion of oceanfront property in what The New York Times described as "the now ironically-named Ocean Township."
While there are four municipalities that retain the Village type of government (Loch Arbour, Ridgefield Park, Ridgewood and South Orange), none of them still use the Village form of government. Loch Arbour was the last to do so, but on December 20, 2011, its residents voted to change to the Walsh Act form of government, with a three-member board of commissioners.
In 1997, Loch Arbour voters rejected a ballot proposal that would have it merge back into Ocean Township by an 88-69 margin, and proposals to merge with Allenhurst or Interlaken failed by a nearly 10-1 margin.
A ballot proposal in 2011 also considered a merger with Allenhurst, citing a potential reduction in property taxes for residents. In 2012, Loch Arbour officials held discussions with their counterparts in Allenhurst towards a plan in which the two municipalities would merge, subject to approval by the councils of both communities and approval of a referendum by voters in both Loch Arbour and Allenhurst. The merger drive was driven by property taxes paid to the Ocean Township School District, a relationship that would be ended by the merger, under which the combined municipality would send students at lower cost to the Asbury Park Public Schools.
