South Phoenix

After Wormser's death on April 25, 1898, most of his real estate holdings were purchased on January 9, 1901, by land and cattle magnate Dwight B.

This land, which includes most of the northeast part of South Phoenix, became the Bartlett-Heard Ranch, which began being subdivided and sold for homesites on March 20, 1910.

Most of the land initially sold from the Ranch was between 7th Avenue and 16th Street, and between Broadway Road and Southern Ave., mostly for small farms, in an area that became known as Roosevelt Place when it was developed into residential homes on one- and 2-acre (8,100 m2) lots in the 1920s.

[3] During 1912–1913, the Highline and Western canals were built to supply water from the Salt River to the South Mountain area, which led to further agricultural development.

In addition to raising cattle, the land was used for raising alfalfa, cotton, oranges and other citrus trees, canaigre (a plant that produces tannin used for tanning leather), and even Louis Janssens' Belgian-American Ostrich Farm, which operated on 230 acres (0.93 km2) of Bartlett-Heard subdivided land until World War I.

Kishiyama successfully experimented with growing flowers near the Western Canal at 40th St. and Baseline Road, and another Japanese family, the Nakagawas, arrived in the area in the 1930s.

After the war was over, the Kishiyama and Nakagawa families returned to the South Mountain area and started over, again successfully raising large fields of flowers, lettuce, and other vegetables along the Baseline corridor.

Census tract 1160, between Broadway and Baseline, has a population of 4,711 and was 56.3% African-American, the highest percentage in the entire state of Arizona.
