About Santa Rosa

Santa Rosa is the county seat of Sonoma County, California United States. The 2010 census reported a population of 167,815. Santa Rosa is the largest city in California's North Coast, Wine Country and the North Bay; the fifth most populated city in the San Francisco Bay Area after San Jose, San Francisco, Oakland, and Fremont; and the 26th most populated city in California. In 2013, Santa Rosa was ranked as one of the "happiest cities" in the United States.

The first known permanent European settlement of Santa Rosa was the homestead of the Carrillo family, in-laws to Mariano Guadalupe Vallejo, who settled the Sonoma pueblo and Petaluma area. In the 1830s, during the Mexican period, the family of María López de Carrillo built an adobe house on their Rancho Cabeza de Santa Rosa land grant, just east of what later became downtown Santa Rosa. Allegedly, however, by the 1820s, before the Carrillos built their adobe in the 1830s, Spanish and Mexican settlers from nearby Sonoma and other settlements to the south raised livestock in the area and slaughtered animals at the fork of the Santa Rosa Creek and Matanzas Creek, near the intersection of modern-day Santa Rosa Avenue and Sonoma Avenue. This is supposedly the origin of the name of Matanzas Creek as, because of its use as a slaughtering place, the confluence came to be called La Matanza.

Santa Rosa lies on the Santa Rosa Plain; its eastern extremities stretch into the Valley of the Moon, and the Sonoma Creek watershed known as the Sonoma Valley, while its western edge lies in the Laguna de Santa Rosa catchment basin.

Due to its population, much of Santa Rosa's remaining undisturbed area is on its urban fringe. However, the principal wildlife corridors of Santa Rosa Creek and its tributaries, flow right through the heart of the town. Great blue herons, great egrets, snowy egrets and black-crowned herons nest in the trees of the median strip on West Ninth Street as well as along Santa Rosa Creek and downtown. Deer often are spotted roaming the neighborhoods nearer the eastern hills, as deep into town as Franklin Avenue and the McDonald area; rafters of wild turkeys are relatively common in some areas, and mountain lions are occasionally observed within the city limits. Raccoons and opossums are a common sight throughout the city, while foxes, and rabbits may be regularly seen in the more rural areas. In addition, the city borders and then wraps around the northern end of Annadel State Park, which itself extends into the Sonoma Mountains and Sonoma Valley. Annadel State Park also adjoins Spring Lake County Park and Howarth Park, forming one contiguous park system that enables visitors to venture into wild native habitats.
