Arbor Hill Historic District–Ten Broeck Triangle
During the Great Migration of the 1920s, many of the African Americans who came north to Albany from the Southern states settled in Arbor Hill, an area that had been one of the first where their predecessors had settled in the city It came to be regarded as more desirable among newcomers than their other destination, the South End. Residents of that neighborhood often moved to Arbor Hill after they had made some money. African Americans displaced by the construction of what is now the State Department of Education Building in 1912 also resettled in Arbor Hill. As early as 1922 many of the city's prominent African-American institutions and organizations, such as churches and social clubs, were located in Arbor Hill. This growth led to the name being applied to the larger area it presently refers to, extending north to the railroad tracks, west to Northern Boulevard (now Henry Johnson Boulevard) and south to Sheridan Avenue.
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.
