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
Midway between First Street and Clinton the boundary turns southeast to follow the rear property line of the lots on first, again the boundary with the Clinton Avenue Historic District. This line becomes Ludlow Alley shortly before North Hawk Street. After a short southward jog to take in the two properties on that street north of Clinton, it returns to the alley and follows it back to Clinton at Ten Broeck.
