Piedmont is a small, mostly-residential, semi-suburban city located in Alameda County, California, United States. The City of Piedmont is completely surrounded by the city of Oakland. Piedmont's residential population was 10,667 at the 2010 census.

The name comes after the region of Piedmont in Italy, and literally means foothill. Piedmont was incorporated in 1907, and was developed significantly in the 1920s and 1930s. The Piedmont Unified School District (PUSD) includes three elementary schools, one middle school, and two high schools.


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 originally 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. On February 27, 1923, voters adopted the charter, which can only be changed by another vote of the people.

Piedmont celebrated the year 2007 as its Centennial Anniversary since incorporation. The Centennial Committee hosted celebratory events along a trail that runs through downtown Piedmont and denoted historical landmarks in the city. The Committee also created a float for the city's Fourth of July parade.

The historical exhibit "A Deluxe Autonomy: Piedmont’s First 100 Years" was on display in the Oakland Public Library from January 5 to March 31, 2007.

Piedmont is located at 37°49′19″N 122°13′53″W / 37.821994°N 122.231405°W / 37.821994; -122.231405.

It is located near the Hayward Fault, a geological fault line that runs through the East Bay region.

According to the United States Census Bureau, the city has a total area of 1.7 square miles (4.4 km2), all land.


Piedmont is a small, residential community located in the East Bay hills. Piedmont is surrounded on all sides by the city of Oakland's more historic residential districts. Specifically, Piedmont's northwestern border is adjacent to Oakland's Piedmont Ave commercial district. Piedmont borders Oakland's historic Grand Lake District (Lakeshore and Grand Ave commercial districts) to the west, Oakland's Rockridge District to the northeast, the quaint and more rustic Montclair District on its eastern border and the Crocker Highlands and Glenview Districts to the southwest.

Major streets

Piedmont's major streets include Oakland Avenue, which runs east–west through Piedmont's small city center; Highland Avenue, which divides Piedmont into upper and lower sections; Moraga Avenue, which runs along the city's northern border; and Grand Avenue, which runs near Piedmont's western border and further distinguishes 'Lower' Piedmont (west of Highland Ave) from 'Baja' Piedmont (west of Grand Ave). Lots in upper Piedmont are, on average, larger than lots in lower Piedmont. A nearby shopping district on Piedmont Avenue is located in Oakland, not Piedmont. A small shopping hamlet had been located on Highland Avenue near the Excedra at Piedmont Park for many years, but in the last few decades has dwindled in number to a small, local grocer-deli (Mulberry's Market), a service station and three banks. No major highways run within Piedmont's borders but entrances to scenic* CA Highway 13 and CA I-580 are quite near. *A 'scenic' designation means no billboards or advertisements are permitted.


Piedmont is almost entirely zoned for single-family dwelling residential use. Piedmont has minimal commerce compared with statistically similar cities, and relies primarily on property taxes and fees for public revenues to support public services. The city also has relatively few multi-family or second (in-law) units. The city has a very small number of businesses in its commercial district on Highland Avenue and a very small number of businesses on Grand Avenue near Piedmont's western border with Oakland.

Emergency Services

Piedmont provides its own fire, police, parks, and recreational services but does not have its own public library nor federal post office; these services are shared with Oakland. Special, incremental property tax assessments on Piedmont real estate for schools and some public services are not shared with Oakland.


The city is served by two local weekly newspapers: the Piedmont Post and the Piedmonter, a neighborhood newspaper organized under the Contra Costa Times news organization.

Piedmont has a City Hall, a Community Hall, a Veterans' Memorial Building, a Recreation Center, Aquatics Center, and Center for the Arts. Public parks include Piedmont Park, Dracena Park, Crocker Park, Hampton Park, Linda Ave Tot Lot and Dog Run, Kennelly Skate Park, and Blair Park. Playfields include Coaches Playfield, Linda Playfield, and Piedmont Sports Field (at Hampton Park).

Regular town events include the July 4th Parade, Movies in the Park, Harvest Festival, Haunted House, Thanksgiving Turkey Trot, and Christmas Tree Lighting. Piedmont High School's annual Bird Calling Contest was previously featured on "The Tonight Show" with Johnny Carson and "The Late Show With David Letterman."

Active charities and community groups include the Piedmont Education Foundation, the Piedmont Historical Society, the Piedmont Center for the Arts, the Piedmont Beautification Foundation, the Daughters of the American Revolution (Piedmont Chapter), the Piedmont League of Women Voters, Dress Best for Less, the Piedmont Highlanders Drums & Pipers, the Piedmont Civic Association, the Piedmont Community Church, the Piedmont East Bay Children's Choir, the Piedmont-Montclair Rotary Club, the Piedmont Boy Scouts, the Piedmont Baseball Foundation, the PIedmont Basketball Foundation, and the Piedmont Soccer Club. The Children's Support League holds annual Heart of the Home tours of Oakland and Piedmont homes.
