Holmdel Township was formed by an act of the New Jersey Legislature on February 23, 1857, from portions of Raritan Township (now Hazlet).[25] The origin of the township's name is unclear, with some sources indicating that it was named for the Holmes family, who were early settlers of the area, while others point to Dutch language words holm and del, meaning 'pleasant valley'.[26][27]
Holmdel's picturesque beauty, proximity to New York City, and main highways, award-winning public schools, large homes, rich history, the PNC Bank Arts Center, and the presence of many high paying jobs within commuting distance led the township to be ranked the #1 "Six-Figure Town" by Money magazine and CNN for 2009.[30]
The township has been one of the state's highest-income communities. Based on data from the American Community Survey (ACS) for 2013–2017, Holmdel Township residents had a median household income of $155,842, ranked 10th in the state among municipalities with more than 10,000 residents, more than double the statewide median of $76,475.[31] Based on data from the 2006–2010 ACS, Holmdel had a per-capita income of $62,120, ranked 46th in the state.[32]
The Lenape people were present in the 1600s when Europeans first showed up in the area that is now Holmdel. Holmdel was part of the Monmouth Tract setup by the English in 1675. The area was part of Middletown township when that was set up in 1693, but, split off in 1848 to form part of Raritan township (now Hazlet) which in turn split off Holmdel Township (February 23, 1857).[35][25]
The PNC Bank Arts Center is a 10,800-seat outdoor amphitheatre concert venue located in Holmdel. PNC Financial Services agreed to a deal in 1996 under which it would pay $9.2 million for the naming rights, as part an effort by the Parkway Authority to avoid toll increases, a deal that was extended for another five years in 2006.[40][41] The facility, which originally opened in 1968, was commissioned by the Garden State Parkway Authority and built based on a design by architect Edward Durell Stone at a cost of $6.75 million (equivalent to $59.1 million in 2023).[42][43] Adjacent to it is the New Jersey Vietnam Veterans Memorial, which opened on May 7, 1995.[44]
