Arbor Hill Historic District–Ten Broeck Triangle
In 1975 several residents of the Ten Broeck Triangle formed the Arbor Hill Concerned Citizens Association (AHCCA) to lobby the city for improvements in neighborhood services. Many of them lived in the surviving townhouses, which they had often restored themselves. They saw gentrification as the key to revitalizing the neighborhood, due to its proximity to downtown Albany and the growing service-sector jobs there. To further this goal, they worked with preservationists to have the triangle recognized as a historic district. That area was duly listed on the Register in 1978 under that name.
Arbor Hill Historic District–Ten Broeck Triangle
Its fortunes began to slip as the city expanded westward, to new neighborhoods like Washington Park which attracted the city's affluent. As the 20th century began, it gradually became a more middle-class neighborhood, then, after the Great Migration, predominantly African American. As an effective racial ghetto, the neighborhood and its historic buildings suffered the effects of disinvestment and decline. The designation of the historic district, and other efforts by preservationists later in the century, have helped reverse that trend, though not completely.
