Altadena is an unincorporated community of Los Angeles County, nestled within the foothills of the San Gabriel Mountains.  It is bordered to the north by the Angeles National Forest and to the south by the city of Pasadena.  In fact, the name Altadena derives from the Spanish alta, meaning "upper", and dena, from Pasadena, meaning "valley".  The Altadena Area office is located minutes from the Rose Bowl Stadium, which hosts the annual Rose Bowl Game and is a National Historic Landmark and a California Historic Civil Engineering landmark.  The Altadena Area office participates annually in both the Tournament of Roses Parade and Rose Bowl Game by providing escorts, traffic control and security.  Another prominent point of interest in Altadena is Christmas Tree Lane, which has been a holiday attraction since 1920 and boasts the oldest large-scale outdoor Christmas lighting venue in the world.

The Altadena Area office is responsible for patrolling approximately 400 square miles, including the unincorporated communities of Altadena, La Crescenta, Chapman Woods and Pasadena.  Our officers also patrol State Route 134 and State Route 710, along with portions of Interstate 210, Interstate 5, State Route 118, and State Route 2 which includes the Glendale Freeway, Angeles Forest Highway and Angeles Crest Highway.  Notably, Angeles Crest Highway is one of the most scenic drives in California, covering 62 iconic miles through the San Gabriel Mountains from La Cañada – Flintridge to State Highway 138 east of Wrightwood.

The Altadena Area is comprised of a diverse workforce with approximately 85 uniformed and civilian members.  Each of our
employees is dedicated to providing the highest level of safety, service, and security to our residents, businesses, and visitors.  Our outreach and educational programs such as: Every 15 minutes, Sober Grad, Impact Teen Drivers, Right Turn, Start Smart, Age Well Drive Smart, and pedestrian and bicycle safety programs help us provide the highest level of safety, service, and security to the community.  We also have an active Explorer Post for community members aged 15 - 21 interested in exploring a career in law enforcement and providing community service throughout the area.  Additionally, we are proud of our Senior Volunteer Program which consists of community members aged 55 and over, looking to give back to their community in an engaging and rewarding way.

Our team of professionals is proud to serve the people of California.  Please feel free to stop by or contact us via telephone or online to allow us the opportunity to demonstrate our commitment to providing excellent service.
