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...)
State Route 52
is a state highway
in the US state of California in San Diego County
, that extends from La Jolla Parkway at Interstate 5
in La Jolla
to SR 67
. It is a freeway for its entire length, and serves as a major east–west route through the northern part of the city of San Diego
. The road connects the major north–south freeways of the county, including I-5, I-805
, SR 163
, SR 125
, and SR 67. SR 52 passes north of the Rose Canyon Fault
before traversing Marine Corps Air Station Miramar
. Construction began in 1966 with the I-5 interchange to La Jolla, and the San Clemente Canyon Road serving as an early predecessor. The freeway was complete all the way to I-805 in 1970, and to Santo Road east of I-15 in 1988. However, the road east of there faced delays from environmentalists over the endangered Least Bell's Vireo
songbird, which faced habitat destruction, as well as those concerned with the destruction of homes and businesses for the right of way
for the freeway. Funding issues delayed the completion of the entire route to SR 67 until 2011, over fifty years after construction began; until then, the city of Santee faced traffic snarls.
