Boerum Hill (pronounced BORE-um) is a small neighborhood in the northwestern portion of the New York City borough of Brooklyn, bounded by Schermerhorn Street to the north and Fourth Avenue to the east. The western border is variously given as either Smith or Court Streets, and Warren or Wyckoff Streets as the southern edge.
Smith Street and Atlantic Avenue are the neighborhood's main commercial districts. The Brooklyn High School of the Arts is located in the neighborhood on Dean Street and Third Avenue. The neighborhood is part of Brooklyn Community District 2 and is served by the NYPD's 84th Precinct.
Boerum Hill is named for the colonial farm of the Boerum family, which occupied most of the area during early Dutch settlement. Most of the housing consists of three-story row houses built between 1840 and 1870. Despite the "hill" in the name, the neighborhood is flat, parts sit atop former marshes that bordered Gowanus Creek. In the 1950s, all the neighborhoods south of Atlantic Avenue and west of Prospect Park were known generically as South Brooklyn. Boerum Hill in particular was sometimes called "North Gowanus." The name "Boerum Hill" was coined in early 1964 by Boerum Hill Association founder Helen Buckler, referencing name of the colonial farmers.
From the early 1970s till about 2003, Boerum Hill was populated mostly by working class and middle-class families. Crime was fairly common and it had one of the higher crime rates in the city because of its small size. In recent decades, since about the late 1990s, gentrification has restored the neighborhood to one of mostly upper-class individuals, though working class families still reside in the immediate area.
In the early twentieth century, many of the buildings were run as boarding houses. Nearby was the union hall for ironworkers, who came to the city to work on bridges and skyscrapers. The north end of Smith Street was the center of New York City's Mohawk community, who came mostly from Akwesasne and Kahnawake, Mohawk reserves in Quebec, Canada. (Akwesasne extends across national boundaries into New York state.) Many of the Mohawk men were ironworkers, while their wives worked at a variety of jobs and created the community for their families. For 50 years, the Mohawk families called their neighborhood "Little Caughnawaga," after the homeland of Kahnawake. Many families would travel back to Kahnawake in the summer.
The Boerum Hill Historic District was first recognized and designated by the New York City Landmarks commission on November 20, 1973, after tireless efforts over many years by the Boerum Hill Association.
In 2012 Boerum hill was ranked #6 in NYC and #1 outside Manhattan in highest neighborhood median home prices among all NYC neighborhoods.
