History
The area along the Naugatuck River, comprising the present Elm Street section of Ansonia and Derby Avenue section of Derby, was first settled by English colonists in 1652; it was originally a part of the township of Derby. Early settlers developed subsistence farming, and used the river for sawmills and gristmills. In 1844, Anson Green Phelps (1781–1853), a merchant and philanthropist, wanted to expand the old borough of Birmingham (the present downtown of the city of Derby) to the north along the west side of the Naugatuck River to enable industrial development. Unable to purchase the land from its owner, in 1844 Phelps acquired land along the east side of the river; today this is Ansonia's downtown section. A canal was dug for river power to drive the factories and businesses in the new industrial village, which Phelps named "Ansonia". He wanted to name the industrial village as "Phelpsville", but learned there was another village in the region by that name. As suggested by a friend, Phelps used his first name as a root instead, resulting in "Ansonia". As industry developed, soon Ansonia became the most populous area of Derby, boasting many factories. The state chartered Ansonia as a borough of Derby in 1864 and amended it in 1871, granting full municipal privileges. In 1888, a petition was circulated in the borough of Ansonia for the purpose of becoming a separate township from Derby. In 1889 the State General Assembly granted the separation, constituting the Borough, Hilltop, West Ansonia, and Elm Street areas as a separate town known as Ansonia. This was the 168th township in the state of Connecticut. In 1893, Ansonia was incorporated as a city, consolidating with the coterminous Town and the old borough. By the end of the 19th century, the city had…
Geography
According to the United States Census Bureau, the city has a total area of , of which is land and , or 2.72%, is water. The city is bisected by the Naugatuck River and spreads out from the river's banks up the hills—some quite steep—of the river valley. On the west side of the river, the city abuts Derby and Seymour along Silver Hill. On the east side, the city's Hilltop neighborhood meets Woodbridge. The land along the river is mostly given over to factory sites (both operational and defunct), with an area of wooded land on the west bank close to the city's northern boundary that belongs to the American Brass Company. In the early 1990s, this site was proposed by Texas company American Ref-Fuel for a solid waste-to-electric energy cogeneration plant. The proposal was controversial, and protests by residents resulted in its defeat. Residential housing occupies most of the land in Ansonia, chiefly one- or two-family houses on plots of a 1/4 acre up to an acre. Larger houses on larger plots are found in the Hilltop neighborhood. The Ansonia Nature Center on Hilltop preserves some open fields and woodlands. An airport once operated on Hilltop on a grass field, at the eastern edge of the city. During the Cold War, the United States military deployed Nike missiles in silos at the airport. Since the military released the airport grounds for other uses, developers have built residential housing there. The Nike base is now adapted as a horse farm with riding stables; few reminders of its former operations remain. Downtown – The original industrial village and later borough of Ansonia.
