One of the first cities in Los Angeles County to incorporate, San Gabriel, California, shares its namesake with and is almost at the westernmost side of the San Gabriel Valley. San Gabriel is just nine miles east of Los Angeles, and is bordered by San Marino, South Pasadena, Alhambra, Monterey Park, Rosemead, Temple City, and the unincorporated East San Gabriel. It’s also bordered on the south by Interstate 10, although California Route 19 isn’t far to the east.


San Gabriel residents are urban and ethnically diverse, with ages averaging in their late 30’s and early 40’s, and most of those residents are married. San Gabriel‘s median household income is close to the state median, which is almost equally earned by both the average demographic as well as the older residents.  Median home values in San Gabriel are at least $100 thousand more than the California state median.


Like other cities in Southern California, San Gabriel lands were home to the Tongva tribe. In 1771, Father Junipero Serra founded the Mission San Gabriel Arcángel. This was the fourth of 21 missions built in California by the Spanish, and is sometimes referred to as the “Pride of the California Missions.” The mission was an important part of San Gabriel colonial life, and remained important through the Mexican-American War. It became a heart of the region, known for its vineyards, art and multicultural focus. The Mission San Gabriel Arcángel still stands as one of California’s historical locations. San Gabriel was one of the first townships in Los Angeles County by 1852, but didn’t incorporate as a city until 1913.


For a taste of the historical in San Gabriel, a few notable places are not to be missed: the Hayes House and Museum, standing since 1887; the Ramona Museum of California History, located in the Mission District and home to the influential Ramona Parlor; and the San Gabriel Mission Playhouse, a popular theater boasting 1400 seats since 1927. For a little fun in the sun and a good game of golf, there’s the San Gabriel Country Club.


San Gabriel‘s city government is headed by a five-member council, whom are elected at large and who serve four-year terms. They appoint a mayor from their number annually. City clerk and city treasurer also serve four-year terms. San Gabriel also utilizes a city manager and city attorney.


As both a small and young city, the San Gabriel Police Department has a focus on maintaining a partnership with the community and developing new methods of problem-solving to maintain San Gabriel‘s high-quality of life. It offers a Crime Prevention Office, which in turn utilizes Crime Stoppers, a neighborhood watch, volunteer residents and private investigators. The San Gabriel crime rate is considered to be low, and remains at least 100 points below the national averages in violent crimes, especially murder and rape. San Gabriel is also well below the national average in property crimes like theft. As the city continues to grow, San Gabriel will have to depend on well trained law enforcement professionals, private investigators and diligent residents for its public safety.
