History[edit] In the mid-1860s, Benjamin Eaton first developed water sources from the Arroyo Seco and Eaton Canyon to irrigate his vineyard near the edge of Eaton Canyon. This made possible the development of Altadena, Pasadena, and South Pasadena. He did the construction for B. D. Wilson and Dr. John Griffin, who jointly owned the Mexican land grant of Rancho San Pascual, about 14,000 acres (57 km2), that was the future sites of these three communities. They hoped to develop and sell this land in a real estate plan called the San Pasqual Plantation. Their efforts failed by 1870, despite Eaton's irrigation ditch that drew water from the site of present-day Jet Propulsion Laboratory in Arroyo Seco. They had failed because the land was relatively inaccessible and few believed crops could thrive that close to the mountains. Eaton tried to sell the land for the partners, and in late 1873 he helped broker a deal with Daniel Berry, who represented a group of investors from Indiana, to buy 4,000 acres (16 km2) of the rancho. This included the land of present-day Altadena, but they developed a 2,500 acres (10 km2) section further south as Pasadena. In 1881, the land that would later become Altadena was sold to John and Fred Woodbury, brothers who launched the subdivision of Altadena in 1887. The land remained primarily agricultural, though several eastern millionaires built mansions along Mariposa Street, and a small community developed through the 1890s and into the next century. Woodbury-Story House (1882), home of Capt. John Woodbury, is extant and occupied In 1880, Capt. Frederick Woodbury, and his brother, John Woodbury of Marshalltown, Iowa, purchased 937 acres (3.79 km2) known as the Woodbury Ranch. John Woodbury established the Pasadena Improvement Company in 1887, with a plot plan of residential development referred to as the Woodbury Subdivision. They contacted Byron O. Clark, who established a nursery in the foothills in 1875, and had since moved away. He called his nursery "Altadena Nursery", a name he coined from the Spanish "alta" meaning "upper", and "dena" from Pasadena. Woodbury asked if he could use the name "Altadena" for his subdivision and Clark agreed. The newly sprouted community of Altadena immediately began to attract millionaires from the East. In 1887 Andrew McNally, the printing magnate from Chicago, and his good friend Col. G. G. Green, had built mansions on what was to become Millionaire's Row; Mariposa Street near Santa Rosa Avenue. Newspaper moguls William Armiger Scripps and William Kellogg built homes side by side just east of Fair Oaks Avenue. A bit farther east, Zane Grey bought a home from Arthur Herbert Woodward, and added a second-floor study. The famous Benziger Publishing Company built a mansion on the corner of Santa Rosa Avenue (Christmas Tree Lane) and Mariposa. Mariposa was taken from the Spanish name for a butterfly. The grandson of Andrew McNally, Wallace Neff, became a famous Southern California architect. He started his career in Altadena with the design and construction of St. Elizabeth of Hungary Catholic Church (parish est.1918, which was dedicated in October 1926. Over the years Altadena has been subject to attempted annexation by Pasadena. Annexation was stopped in 1956 by community campaigns, though it has been resurrected several times since by Pasadena without success. Had the annexation succeeded, Pasadena would be the 108th largest city in the United States. While Altadena long refused wholesale annexation by neighboring Pasadena, the larger community nibbled at its edges in several small annexations of neighborhoods through the 1940s. With early 1960s redevelopment in Pasadena, the routing of extensions of 134 and 210 freeways, and lawsuits over the desegregation of Pasadena Unified School District, there was white flight and convulsive racial change in Altadena. In 1960, its black population was under four percent; over the next 15 years, half the Caucasian population left, and was replaced by people of color, many of whom settled on the west side of town after being displaced by Pasadena's redevelopment and freeway projects. The name Altadena derives from the Spanish alta, meaning "upper", and dena from Pasadena; the area is adjacent to, but at a higher elevation than, Pasadena.[5]

The most rainfall in one month was 19.70 inches (500.4 mm) in February 1980. The most rainfall in 24 hours was 7.70 inches (195.6 mm) on March 2, 1938. Altadena averages 21.09 inches (535.7 mm) of rain a year, over 6 inches (150 mm) more than nearby Los Angeles due to the orographic effect created by the San Gabriel Mountains. Because of the slope on which the city is built, sewer lines in the city's northern section have been known to overflow significantly.[citation needed]

Arts and culture[edit] Points of interest[edit] Christmas Tree Lane Christmas Tree Lane is a 0.7-mile (1.1 km) stretch of Santa Rosa Avenue from Woodbury Road to Altadena Drive. It has been a holiday attraction since 1920, and it is the oldest large-scale outdoor Christmas lighting venue in the world. Each December, members of the Christmas Tree Lane Association[13] festoon the 110 still standing giant deodars that line the street with thousands of Christmas lights. Christmas Tree Lane was placed on the National Register of Historic Places in 1990, and is a California Historical Landmark. Among Altadena's Christmas lighting attractions is the Balian Mansion, which draws people worldwide for tours of its Christmas lighting display. The Balian Mansion has been lighted since 1955, and is arguably the pioneer of home holiday lighting. The Balian Mansion is located just east of Allen Avenue, at the 3-point junction of Mendocino Street, Mendocino Lane, and Glenview Terrace. The historic Mount Lowe Railway was a scenic railway that once carried passengers to any of four resort hotels high in the San Gabriel Mountains above Altadena and Pasadena. Although the mountains and the remains of the railway are not strictly in Altadena, the most direct trail to the sites, the Sam Merrill Trail, starts in Altadena at the top of Lake Avenue, and leads to Mount Echo, about 3 miles (4.8 km). Chaney Trail, just west of the intersection at Fair Oaks Avenue and Loma Alta Street, is a forestry service road leading to the old right of way. The Mount Lowe Railway site was placed on the National Register of Historic Places in 1993. Altadena has a number of hiking trails, including the trail to the Dawn Mine, which can be reached via Chaney Trail to Sunset Ridge Trail. Arrows painted on large boulders direct hikers along the way. The Cobb Estate at the top of Lake Avenue is now a free botanical garden, operated by the United States Forest Service. It is guarded by its historic gates, which are easily bypassed to allow visitors and hikers to ascend its long and winding paved driveway to the site of what was once one of Altadena's premier mansions. This site is also found alongside the Sam Merrill Trail, which accesses Las Flores Canyon on the way to Echo Mountain. Farnsworth Park located on Lake Avenue is a large county park that offers picnic grounds, play areas, and a club house and amphitheater. It was placed on the National Register of Historic Places in 1997.

Infrastructure[edit] The Los Angeles County Sheriff's Department (LASD) operates the Altadena Station in Altadena.[14] The California Highway Patrol operates the Altadena Area Office on Windsor Dr. in Altadena. Altadena is a shared jurisdiction where L.A. County Sheriff's Dept. handles crime-related calls and CHP handles traffic-related calls. The Los Angeles County Department of Health Services operates the Monrovia Health Center in Monrovia, serving Altadena.[15]

Official tree and flower[edit] The Deodar Cedar (Cedrus deodara) is Altadena's official tree. Indigenous to the Himalayas, the deodar was imported as seeds in 1883, by founder John Woodbury, who had admired the trees in Italy. After growing for two years, they were transplanted to Santa Rosa Avenue, where they now line Christmas Tree Lane. The official flower is the California Golden Poppy (Eschscholzia californica).[citation needed]
