Sheridan Hollow, Albany, New York
On a map made by De Witt in 1790 the name of Arbor Hill makes its first appearance on a map of Albany. In this map Arbor Hill is located in Sheridan Hollow between Orange Street and Clinton Avenue (south and north) and from Chapel Street halfway to Hawk Street (east to west); later Arbor Hill would be the name given to the Ten Broeck Mansion and surrounding neighborhood on the other side of Clinton Avenue, the former village of Colonie. On this same map a "Negro burial ground" is shown along the southern rim of the Hollow, this burial ground does not show up on any subsequent maps and it may never have been plotted and used.
Arbor Hill Historic District–Ten Broeck Triangle
All but three of the 220 buildings in the district are contributing properties to its historic character. Of those 217, the vast majority are houses. One, the Ten Broeck Mansion, is individually listed on the Register as well. Some others have distinctive characteristics within the district.
In 2003 two planning firms hired by the city sought citizen input and created the Arbor Hill Citizen Advisory Committee, which developed a plan to improve life in Arbor Hill as a whole. Among the aspects considered was how the historic district could benefit the neighborhood's future. The Ten Broeck Triangle, it noted, was one of three areas of Arbor Hill where property values did not suffer from the neighborhood's bad reputation. "It is not unusual to
see an abandoned building next to a home in which a property owner has invested $300,000 or more," in the triangle, the report said. "Clearly, to the extent that neighborhood-wide problems are alleviated or solved, property owners in the Ten Broeck neighborhood will greatly benefit and market values can be expected to escalate rapidly."
