Coastal California, also known as the California Coastline and the Golden Coast, refers to the coastal regions of the U.S. state of California. The term is not primarily geographical as it also describes an area distinguished by cultural, economic and political attributes.
The area includes the North Coast, San Francisco Bay Area, Central Coast, and South Coast. The coastline is slowly eroding due to natural processes accelerated by climate change, though much more slowly in other places in the United States. In the last 100 years, the water line has risen less than 6 in (150 mm) along the coast of California. In the next 100 years, the water is expected to surge as much as 9 ft (2.7 m), bringing into question the fate of the many million dollar homes settled right on the edge of the sea. [1] [2]
Coastal California is heavily influenced by east–west distances to the dominant cold California Current as well as microclimates. Due to hills and coast ranges having strong meteorological effects, summer and winter temperatures (other than occasional heat waves) are heavily moderated by ocean currents and fog with strong seasonal lags compared to interior valleys as little as 10 mi (16 km) away. Point Conception tends to divide the Coastal region by mid-summer into warmer (south and east) and cooler zones (north). Peak and often intense heat tends to arrive in September much later than the rest of the nation or state. Over time, droughts and wildfires have increased in frequency and become less seasonal and more year-round, further straining the region's water security. [3] [4] [5] Furthermore, extended droughts and decadal changes in land use are causing severe shoreline retreat to the coast of the Gulf of Santa Catalina. [6]
The counties commonly seen as constituting coastal California are:
During the 2000 Census, roughly a third of households had incomes exceeding $75,000, compared to 17.6% in the Central Valley and 22.5% at the national average. While the area has always been relatively expensive, when compared to inland regions and the national average, the recent[ when? ] real estate boom has left it as the most expensive housing market in the nation. An October 2004 CNN Money publication found that a 2,200-square-foot (200 m2) home in a "middle management neighborhood" would cost an average of $1.8 million. [7]
The San Francisco Peninsula is a peninsula in the San Francisco Bay Area that separates San Francisco Bay from the Pacific Ocean. On its northern tip is the City and County of San Francisco. Its southern base is Los Altos and Mountain View, in Santa Clara County, south of Palo Alto and north of Sunnyvale. Most of the Peninsula is occupied by San Mateo County, between San Francisco and Santa Clara counties, and including the cities and towns of Atherton, Belmont, Brisbane, Burlingame, Colma, Daly City, East Palo Alto, El Granada, Foster City, Half Moon Bay, Hillsborough, La Honda, Loma Mar, Los Altos, Los Altos Hills, Menlo Park, Millbrae, Mountain View, Pacifica, Palo Alto, Pescadero, Portola Valley, Redwood City, Redwood Shores, San Bruno, San Carlos, San Mateo, South San Francisco, West Menlo Park and Woodside.
California is a U.S. state on the western coast of North America. Covering an area of 163,696 sq mi (423,970 km2), California is among the most geographically diverse states. The Sierra Nevada, the fertile farmlands of the Central Valley, and the arid Mojave Desert of the south are some of the geographic features of this U.S. state. It is home to some of the world's most exceptional trees: the tallest, most massive, and oldest. It is also home to both the highest and lowest points in the 48 contiguous states.
State Route 1 (SR 1) is a major north–south state highway that runs along most of the Pacific coastline of the U.S. state of California. At 656 miles (1,056 km), it is the longest state route in California, and the second-longest in the US after Montana Highway 200. SR 1 has several portions designated as either Pacific Coast Highway (PCH), Cabrillo Highway, Shoreline Highway, or Coast Highway. Its southern terminus is at Interstate 5 (I-5) near Dana Point in Orange County and its northern terminus is at U.S. Route 101 (US 101) near Leggett in Mendocino County. SR 1 also at times runs concurrently with US 101, most notably through a 54-mile (87 km) stretch in Ventura and Santa Barbara counties, and across the Golden Gate Bridge.
Malibu is a beach city in the Santa Monica Mountains region of Los Angeles County, California, about 30 miles (48 km) west of Downtown Los Angeles. It is known for its Mediterranean climate, its strip of beaches stretching 21 miles along the Pacific Ocean coast, and for its longtime status as the home of numerous affluent Hollywood celebrities and executives. Although a high proportion of its residents are entertainment industry figures with multi-million dollar mansions, Malibu also features several middle- and upper-middle-class neighborhoods. The Pacific Coast Highway traverses the city and has led most residents to settle anywhere from half a mile to within a few hundred yards of it, with some residents living up to one mile away from the beach in areas featuring narrow canyons. As of the 2020 census, the city's population was 10,654.
Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms. The landward retreat of the shoreline can be measured and described over a temporal scale of tides, seasons, and other short-term cyclic processes. Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural.
The Central Coast is an area of California, roughly spanning the coastal region between Point Mugu and Monterey Bay. It lies northwest of Los Angeles and south of the San Francisco Bay Area, and includes the rugged, rural, and sparsely populated stretch of coastline known as Big Sur.
Beach nourishment describes a process by which sediment, usually sand, lost through longshore drift or erosion is replaced from other sources. A wider beach can reduce storm damage to coastal structures by dissipating energy across the surf zone, protecting upland structures and infrastructure from storm surges, tsunamis and unusually high tides. Beach nourishment is typically part of a larger integrated coastal zone management aimed at coastal defense. Nourishment is typically a repetitive process because it does not remove the physical forces that cause erosion; it simply mitigates their effects.
Central California is generally thought of as the middle third of the U.S. state of California, north of Southern California and south of Northern California. It includes the northern portion of the San Joaquin Valley, part of the Central Coast, the central hills of the California Coast Ranges and the foothills and mountain areas of the central Sierra Nevada.
The California State Coastal Conservancy is a non-regulatory state agency in California established in 1976 to enhance coastal resources and public access to the coast. The CSCC is a department of the California Natural Resources Agency. The agency's work is conducted along the entirety of the California coast, including the interior San Francisco Bay and is responsible for the planning and coordination of federal land sales to acquire into state land as well as award grant funding for improvement projects. The Board of Directors for the agency is made up of seven members who are appointed by the Governor of California and approved by the California Legislature, members of the California State Assembly and California State Senate engage and provide oversight within their legislative capacity.
Goleta Beach is a region of coastline located near Goleta, California, just east of the University of California, Santa Barbara (UCSB) campus. A portion of the shore of Goleta Bay is managed by the County of Santa Barbara, as the Goleta Beach County Park (GBCP). The beach itself is partly man-made as sand was spread onto an existing sandspit in 1945. The beach is a seasonal habitat for migrating shorebirds, including the snowy plover, an endangered species, and is occasionally closed due to nourishment efforts.
The California Coastal Commission (CCC) is a state agency within the California Natural Resources Agency with quasi-judicial control of land and public access along the state's 1,100 miles (1,800 km) of coastline. Its mission as defined in the California Coastal Act is "to protect, conserve, restore, and enhance the environment of the California coastline".
The Oxnard Plain is a large coastal plain in southwest Ventura County, California, United States surrounded by the mountains of the Transverse Ranges. The cities of Oxnard, Camarillo, Port Hueneme and much of Ventura as well as the unincorporated communities of Hollywood Beach, El Rio, Saticoy, Silver Strand Beach, and Somis lie within the over 200-square-mile alluvial plain (520 km2). The population within the plain comprises a majority of the western half of the Oxnard-Thousand Oaks-Ventura Metro Area and includes the largest city along the Central Coast of California. The 16.5-mile-long coastline (26.6 km) is among the longest stretches of continuous, linear beaches in the state.
Pacifica State Beach is the southernmost of Pacifica, California's large beaches. It is a 0.75-mile-long (1.21 km) crescent-shaped beach located at the mouth of the San Pedro Valley in downtown Pacifica off State Route 1, in San Mateo County. Over one million people visit this beach annually.
The 2008 California wildfire season was one of the most devastating in the state of the 21st century. While 6,255 fires occurred, about two-thirds as many as in 2007, the total area burned— 1,593,690 acres —far exceeded that of previous years.
The climate of Los Angeles is mild to hot year-round, and mostly dry. It is classified as borderline Mediterranean and semi-arid. The city is characterized by seasonal changes in rainfall—with a dry summer and a winter rainy season. Under the Köppen climate classification, the coastal areas are classified as BSh and Csb, while the inland areas are classified as BSh and Csa.
The California Coastal Trail, or CCT, is an environmental project by the California Coastal Conservancy, an organization developed to enhance coastal resources and promote access to the shore in 2001.
The California coastal sage and chaparral is a Mediterranean forests, woodlands, and scrub ecoregion, defined by the World Wildlife Fund, located in southwestern California and northwestern Baja California (Mexico). It is part of the larger California chaparral and woodlands ecoregion. The ecoregion corresponds to the USDA Southern California ecoregion section 261B, and to the EPA Southern California/Northern Baja Coast ecoregion 8.
Aptos Creek is a southward flowing 9.5 miles (15.3 km) creek that begins on Santa Rosalia Mountain on the southwestern slope of the Santa Cruz Mountains in Santa Cruz County, California and enters Monterey Bay, at Seacliff State Beach in Aptos, California.
The Gaviota Coast in Santa Barbara County, California is a rural coastline along the Santa Barbara Channel roughly bounded by Goleta Point on the south and the north boundary of the county on the north. This last undeveloped stretch of Southern California coastline consists of dramatic bluffs, isolated beaches and terraced grasslands.
The 2022 California wildfire season was a series of wildfires throughout the U.S. state of California. By the end of the year, a total of 7,667 fires had been recorded, totaling approximately 363,939 acres across the state. Wildfires killed nine people in California in 2022, destroyed 772 structures, and damaged another 104. The 2022 season followed the 2020 and 2021 California wildfire seasons, which had the highest and second-highest (respectively) numbers of acres burned in the historical record, with a sharp drop in acreage burned.
