San Diego County is a county located in the southwestern corner of the State of California. As of the 2010 census, the population was 3,095,313, making it the second-most populous county in California and the fifth-most populous in the United States. Its county seat is San Diego, the eighth-most populous city in the United States. It is the south-westernmost county in the 48 contiguous United States.
San Diego County comprises the San Diego-Carlsbad, CA Metropolitan Statistical Area. It is also part of the San Diego–Tijuana metropolitan area, the largest metropolitan area shared between the United States and Mexico.
San Diego County has 70 miles (110 km) of coastline. Most of the county has a mild Mediterranean climate to semiarid climate, though there are mountains that receive frost and snow in the wintertime.
There are also 16 naval and military installations of the U.S. Navy, U.S. Marine Corps, and the U.S. Coast Guard in San Diego County. These include the Naval Base San Diego, Marine Corps Base Camp Pendleton, Marine Corps Air Station Miramar, and Naval Air Station North Island.
Arising from an effort by the state government to identify regional economies, San Diego County and Imperial County are part of the Southern Border Region, one of nine such regions. As a regional economy, the Southern Border Region is the smallest but most economically diverse region in the state. However, the two counties maintain weak relations and have little in common aside from their common border.
From north to south, San Diego County extends from the southern borders of Orange County and Riverside County to the Mexico–United States border and Baja California. From west to east, San Diego County stretches from the Pacific Ocean to its boundary with Imperial County. (Full article...)
The Panama–California Exposition
was an exposition
held in San Diego
between March 9, 1915 and January 1, 1917. The exposition celebrated the opening of the Panama Canal
, and was meant to tout San Diego as the first U.S. port of call for ships traveling north after passing westward through the canal. The fair was held in San Diego's large urban Balboa Park
Real estate developer "Colonel" David Collier was responsible for selecting both the location in the city park and a Pueblo Revival and Mission Revival architectural style. This mix of influences at San Diego proved popular enough to earn its own name: Spanish Colonial Revival. The elegant Cabrillo Bridge was built to span the canyon or arroyo, and the appearance of its long horizontal stretch ending in a great upright pile of fantasy buildings would be the crux of the whole composition. Several of the Exposition's permanent buildings still stand in the park and are featured as museums.
