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.
Barton Hills, Michigan
Located within Ann Arbor Charter Township and adjacent to the city of Ann Arbor, the community was originally named "Huron Farms" and was established by the Detroit Edison Company in 1913. The company acquired land on both sides of the Huron River and built a series of dams for electric power production. Land owned by the company was also used for agricultural purposes, including farms, dairy cattle, and fruit orchards. As the area where the village is currently located was too hilly for farming, it was instead promoted by the company as an exclusive residential community for company executives. Membership in the Barton Hills Country Club was considered by many to be a mark of distinction. As homes were constructed in the 1920s, restrictions attached to each deed stipulated that the homes must be designed by a registered architect.
By the 1940s, through the economic and social turmoil of the Great Depression and World War II, the community had become an economic liability for a public utility. The company shareholders decided to make an outright gift of its holding to the residents of the community in exchange for assuming responsibility for maintaining the water system, roads, and other municipal services.
