Annual events

Armonk is host to several annual events. The Armonk Outdoor Art Show is a fine art and crafts juried show sponsored by Friends of the North Castle Public Library ("the Friends") where approximately 200 artists gather at Community Park to show and sell their work.[15] The event involves local volunteers with the proceeds from the show benefiting the North Castle Public Library and its Whippoorwill Hall performance auditorium. One week before the Art Show, the Armonk Chamber of Commerce sponsors the "Jamie's 5K Run For Love" run/walk road race.[16] The proceeds from this event also go to the library with a portion reserved specifically for children's programs. The Friends also sponsors the Armonk Players, a community theater group that stages two full productions and several readings each year at Whippoorwill Hall.[17]

In addition, the Armonk chapter of the Lions Club sponsors a Fol-De-Rol, held during either the first or second weekend in June.[18] The four-day event takes place in Wampus Brook Park and by Wampus Elementary School. It draws local businesses and artisans to set up tents and sell their merchandise. In addition, local restaurants set up tents to sell food and there are rides and midway games for children. Local student and professional music groups play in the gazebo to entertain the crowds.

Armonk also holds a community-wide Relay For Life during the first weekend in May. The event is sponsored locally by the Byram Hills chapter of Youth Against Cancer.

The latest Armonk tradition is Frosty Day.[19] A parade goes down Main Street onto Bedford Road, past the "Village Square" mentioned in the song "Frosty the Snowman" to Wampus Brook Park for a gala holiday lighting ceremony. Steve Nelson, the song's lyricist, was a frequent visitor to Armonk after World War II from his home in nearby White Plains. In 1950, he wrote the song's lyrics which he put to Walter E. Rollins' music; it was the same year that he was looking for land in Armonk on which to build his new home.

Housing boom and construction

Armonk experienced a surge in new housing construction and development beginning in the late 1990s. New condominiums, town houses, and larger single-family homes were constructed primarily north of the Armonk business district and just to the west. Armonk's Thomas Wright Estates or Sands Mill Estates, consisting primarily of large homes, were constructed in the late 1990s and early 2000s. Armonk real estate prices have increased substantially since the late 1990s, having peaked in the mid-2000s, and never returning to their pre-2000s rates despite the subprime mortgage crisis. The new construction projects and increased housing costs have increased Armonk's recent reputation as an affluent town, with the residents' profile moving away from the middle-working class and towards a much wealthier upper class image. In a construction project, a real estate company purchased the long-standing Schultz's Cider Mill just south of Main Street and had it razed. The company then constructed a premium gated community of 27 townhouses and homes (named "Cider Mill") in its place. As a result, the population of Armonk increased significantly but caused the public schools to become overcrowded and push forth a series of expensive school expansion projects that significantly raised property taxes.

Much of the new construction was pinned on the connections that former Town Supervisor John Lombardi had with the areas' construction and development companies. In 2005, after over 40 years in office, Lombardi was ousted in the election by political newcomer Reese Berman. A former librarian at the town's middle school, Berman's campaign promise was to put a moratorium on new residential construction to be enacted during her term in office. As of Berman's election, no new purely residential projects have broken ground in Armonk. A new community; Cider Mill was added in 2007–2008.


Armonk Square is a 3.5-acre development of shops, banking center, offices, one-bedroom apartments and food market.

Organizations located in the hamlet include Whippoorwill Country Club and the North Castle Public Library, which is part of the Westchester Library System.
