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.

The affluent families that had lived in the Ten Broeck area began moving to the newer neighborhoods in the city's undeveloped western sections, which offered larger houses and larger lots in the newer suburban style of living. They rented the houses they left behind or sold them, with the result that many were subdivided into multiple units, making the Ten Broeck Triangle less exclusive than it had been for the previous 50 years.
