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.
Mission Hill, Boston
Like the adjacent neighborhood of Jamaica Plain to the south, Mission Hill was once a neighborhood of adjacent Roxbury before Roxbury's annexation by Boston. According to maps from the period, it was often referenced as Parker Hill (which is the name of the geographic feature in the area). After annexation (and more rapidly in recent years) the area slowly came to be considered a separate neighborhood of its own right. The majority of government, commercial, and institutional entities list "Mission Hill" in the breakdown of Boston neighborhoods and its boundaries generally agreed upon.
