About Piedmont, CA

The original neighborhood of Piedmont was larger than the current municipality of Piedmont, with the Mountain View Cemetery considered full part of the Piedmont neighborhood. Residents initially sought incorporation in 1907. Two elections were held among the citizens of Piedmont in 1907, both of which narrowly upheld the decision for Piedmont to become a separate city, rather than become a neighborhood within the city of Oakland. According to the city's Web page, "In the Roaring Twenties, Piedmont was known as the 'City of Millionaires' because there were more millionaires per square mile than in any city in the United States." Many of these millionaires built mansions that still stand, notably on Sea View Avenue and Sotelo Avenue/Glen Alpine Road in 'Alta' Piedmont. Piedmont became a charter city under the laws of the state of California on December 18, 1922.
