California State Route 160
–
State Route 160 is a state highway in the U. S. state of California consisting of two sections. The longer, southern, section is a highway through the alluvial plain of the Sacramento River. The entire southern portion, from SR4 to Sacramento, is part of the State Scenic Highway System, State Route 160 begins in eastern Antioch at SR4. After two interchanges, the highway rises onto the two lane Antioch Bridge over the San Joaquin River and it cuts north across the center of Sherman Island, reaching the Sacramento River on the opposite shore. After passing Isleton, the crosses the river on the Isleton Bridge, a bascule bridge built in 1923, and runs along the west shore on Grand Island. On the mainland, SR160 once again atop the east levee. The final bridge over the river is the Freeport Bridge, which carries County Route E9 to the west levee, about a mile beyond the Freeport Bridge, SR160 leaves the levee, enters the city of Sacramento, passes under I-5, and farms give way to suburbs. Here the former SR160 is known as Freeport Boulevard, a surface road that passes the Sacramento Executive Airport. Freeport Boulevard turns to the northwest at about 4th Avenue and it was formerly a one-way pair with 21st Street with Freeport heading one-way southbound and 21st heading one-way northbound. The city converted these streets back to streets for traffic calming purposes in 2008. After a short jog west on Broadway, former SR160 turns north on the pair of 15th and 16th Streets, almost immediately crossing Business 80. 15th and 16th Streets lead traffic north past the east side of the State Capitol grounds, 12th Street remains a one-way southbound roadway, but the two-way RT Light Rail now occupies its east side. The light rail, which crosses the river between the two directions of SR160, soon leaves at the Del Paso Boulevard interchange as the freeway turns east. Two folded diamonds at local streets and an entrance ramp from Tribute Road are all that remains before SR160 merges with Business 80 at the Arden Way interchange. Business 80 is also known as the Capital City Freeway here, two bascule bridges—the Paintersville Bridge and Isleton Bridge—replaced the free ferries in 1923, and are of a type patented by Joseph B. Strauss, who went on to design the Golden Gate Bridge, local businessmen Aven Hanford and Oscar Klatt replaced the toll ferry with the tolled Antioch Bridge in mid-1926, almost a year before they opened the larger Carquinez Bridge to the west. The legislature added this road to the highway system in 1933, and it became part of Legislative Route 11. This part of Route 11 was not assigned a route number in 1934, but, by 1937

San Joaquin River
–
The San Joaquin River /ˈsæn wɑːˈkiːn/ is the longest river of Central California in the United States. An important source of water as well as a wildlife corridor. People have inhabited the San Joaquin Valley for more than 8,000 years, the newcomers quickly appropriated the rich natural and hydrologic resources of the watershed for use in farms and cities, but found themselves plagued by flood and drought. Because of the topography of the San Joaquin Valley, floods once transformed much of the lower river into a huge inland sea. In the 20th century, many levees and dams were built on the San Joaquin and these engineering works changed the fluctuating nature of the river forever, and cut off the Tulare Basin from the rest of the San Joaquin watershed. The river was called many different names, at different parts of the river were known by different names. The present name of the dates to 1805–1808, when Spanish explorer Gabriel Moraga was surveying east from Mission San José in order to find possible sites for a mission. Moraga named a tributary of the river for Saint Joachim, husband of Saint Anne and father of Mary, the name Moraga chose was later applied to the entire river, it was in common use by 1810. In the Mono language, the river is called typici h huu, a member of the Pedro Fages party in 1772, Crespis vantage point was the hilltops behind modern San Francisco. Another early name was Rio San Juan Bautista, the origin of which is unknown.8 mi southeast of Mount Lyell, the Middle Fork is usually considered part of the main stem. The South Fork, which begins at Martha Lake in Kings Canyon National Park and flows through Florence Lake, from the mountainous alpine headwaters, the San Joaquin flows generally south into the foothills of the Sierra, passing through four hydroelectric dams. It eventually emerges from the foothills at what was once the town of Millerton, the location of Friant Dam since 1942, which forms Millerton Lake. Below Friant Dam, the San Joaquin flows west-southwest out into the San Joaquin Valley – the southern part of the Great Central Valley – passing north of Fresno, from Mendota, the San Joaquin swings northwest, passing through many different channels, some natural and some man-made. Northeast of Dos Palos, it is joined by the Fresno. Fifty miles downstream, the Merced River empties into an otherwise dry San Joaquin, the majority of the river flows through quiet agricultural bottomlands, and as a result its meandering course manages to avoid most of the urban areas and cities in the San Joaquin Valley. About 11 mi west of Modesto, the San Joaquin meets its largest tributary, near Vernalis, it is joined by another major tributary, the Stanislaus River. About 40 mi from the mouth, the river draws abreast to the flank of Stockton. From here to the mouth, the river is dredged as part of a navigation project, past the head of tide, amid the many islands of the delta, the San Joaquin is joined by two more tributaries, the Calaveras River and the larger Mokelumne

Antioch, California
–
Antioch is a city in Contra Costa County, California, United States. Located in the East Bay region of the San Francisco Bay Area along the San Joaquin-Sacramento River Delta, it is a suburb of San Francisco, the citys population was 102,372 at the 2010 census and estimated to be 110,542 in 2015. Antioch is one of the oldest towns in California, in 1848, John Marsh, owner of Rancho Los Meganos, one of the largest ranches in California, built a landing on the San Joaquin River in what is now Antioch. It became known as Marshs Landing, and was the point for the 17. It included a pier extending out into the river, enabling vessels drawing 15 feet of water to tie up there at any season of the year. In 1850, two brothers, William and Joseph Smith, founded a town slightly west of Marshs Landing, in 1851, the towns new minister persuaded the residents to change the name of the town to Antioch, for the biblical city of Antioch. This new industry resulted in the founding of the towns of Nortonville, Somersville, Stewartsville, and Black Diamond, the Empire Coal Company was formed by John C. Rouse and George Hawxhurst in 1876, which built a railroad that passed from Antioch toward the mines over what is now F Street, however, later on, both the mine and the railroad passed into the hands of the Belshaw brothers. In 1863, a great excitement arose over the discovery of ore near Antioch. Smelting works were built at Antioch, and a value of fifteen to twenty-five dollars per ton was paid for the ore, unfortunately the copper bubble eventually burst, to the dismay of the citizens with connections. Petroleum was first drilled for near Antioch in 1865, but not enough oil was found to make a decent profit. The Antioch Post Office was opened in 1851, closed in 1852, re-opened in 1855, closed again in 1862, the city of Antioch was incorporated in 1872. The Antioch Ledger was first issued on March 10,1870, in memory of when the paper was formed, a copy of its first issue has been framed and hangs over the desk of the present editor. It is five by eight inches in size, printed on one side only, the Ledger later merged with the Contra Costa Times and printed its last issue in 2005. Today, Antioch is mainly a community, with most adults working in larger cities toward Oakland. However, the Contra Costa Times and affiliated newspapers contradicted their claim, Disturbing, only its not, according to a Bay Area News Group analysis of sex offender addresses and census data. Monte Rio ranked first with 4.5 per 1000, the city was attempting in 2012 to annex an adjacent 678-acre area of unincorporated land, which includes a GenOn Energy 760-megawatt power plant, to include the plant within city limits. Antioch is located at 38°00′18″N 121°48′21″W, along the San Joaquin River at the end of the San Joaquin-Sacramento River Delta

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

California
–
California is the most populous state in the United States and the third most extensive by area. Located on the western coast of the U. S, California is bordered by the other U. S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. Los Angeles is Californias most populous city, and the second largest after New York City. The Los Angeles Area and the San Francisco Bay Area are the nations second- and fifth-most populous urban regions, California also has the nations most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The Central Valley, an agricultural area, dominates the states center. What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries, the Spanish Empire then claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its war for independence. The western portion of Alta California then was organized as the State of California, the California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom. If it were a country, California would be the 6th largest economy in the world, fifty-eight percent of the states economy is centered on finance, government, real estate services, technology, and professional, scientific and technical business services. Although it accounts for only 1.5 percent of the states economy, the story of Calafia is recorded in a 1510 work The Adventures of Esplandián, written as a sequel to Amadis de Gaula by Spanish adventure writer Garci Rodríguez de Montalvo. The kingdom of Queen Calafia, according to Montalvo, was said to be a land inhabited by griffins and other strange beasts. This conventional wisdom that California was an island, with maps drawn to reflect this belief, shortened forms of the states name include CA, Cal. Calif. and US-CA. Settled by successive waves of arrivals during the last 10,000 years, various estimates of the native population range from 100,000 to 300,000. The Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups also were diverse in their organization with bands, tribes, villages. Trade, intermarriage and military alliances fostered many social and economic relationships among the diverse groups, the first European effort to explore the coast as far north as the Russian River was a Spanish sailing expedition, led by Portuguese captain Juan Rodríguez Cabrillo, in 1542. Some 37 years later English explorer Francis Drake also explored and claimed a portion of the California coast in 1579. Spanish traders made unintended visits with the Manila galleons on their trips from the Philippines beginning in 1565

Carpool
–
Carpooling is the sharing of car journeys so that more than one person travels in a car. By having more people using one vehicle, carpooling reduces each persons travel costs such as costs, tolls. Authorities often encourage carpooling, especially during periods of high pollution or high fuel prices, in 2009, carpooling represented 43. 5% of all trips in the United States and 10% of commute trips. The majority of carpool commutes are fam-pools with family members, carpool commuting is more popular for people who work in places with more jobs nearby, and who live in places with higher residential densities. However, carpooling is significantly less likely among people who spend time at work, older workers. Drivers and passengers offer and search for journeys through one of the several mediums available, after finding a match they contact each other to arrange any details for the journey. Costs, meeting points and other details like space for luggage are agreed on and they then meet and carry out their shared car journey as planned. Carpooling is commonly implemented for commuting but is popular for longer one-off journeys. Carpooling is not always arranged for the length of a journey. Especially on long journeys, it is common for passengers to join for parts of the journey. This gives carpooling extra flexibility, and enables people to share journeys. Like other online marketplaces, they use community-based trust mechanisms, such as user-ratings, many companies and local authorities have introduced programs to promote carpooling. In an effort to reduce traffic and encourage carpooling, some governments have introduced high-occupancy vehicle lanes in which only vehicles with two or more passengers are allowed to drive, HOV lanes can create strong practical incentives for carpooling by reducing travel time and expense. In some countries it is common to find parking spaces reserved for carpoolers, in 2011, an organization called Greenxc created a campaign to encourage others to use this form of transportation in order to reduce their own carbon footprint. Several people were fined by undercover tax officers during a 2011 crackdown, Carpooling usually means to divide the travel expenses in equal parts between all the occupants of the vehicle. The driver doesn’t try to earn money, but to share with several people the cost of a trip he would do anyway, the expenses to be divided basically include the fuel and possible tolls. But if we include in the calculation the amortization of the purchase and maintenance, insurance and taxes paid by the driver. There are platforms that facilitate carpooling by connecting people seeking respectively passengers and drivers, usually there is a fare set up by the car driver and accepted by passengers, because they get an agreement before trip start

San Francisco Bay
–
San Francisco Bay is a shallow estuary in the U. S. state of California. It is surrounded by a region known as the San Francisco Bay Area, dominated by the large cities San Francisco, Oakland. San Francisco Bay drains water from approximately 40 percent of California and it then connects to the Pacific Ocean via the Golden Gate strait. However, this group of interconnected bays is often called the San Francisco Bay. The bay was designated a Ramsar Wetland of International Importance on February 2,2013, the bay covers somewhere between 400 and 1,600 square miles, depending on which sub-bays, estuaries, wetlands, and so on are included in the measurement. The main part of the bay measures 3 to 12 miles wide east-to-west and it is the largest Pacific estuary in the Americas. Later, wetlands and inlets were filled in, reducing the Bays size since the mid-19th century by as much as one third. Recently, large areas of wetlands have been restored, further confusing the issue of the Bays size, despite its value as a waterway and harbor, many thousands of acres of marshy wetlands at the edges of the bay were, for many years, considered wasted space. As a result, soil excavated for building projects or dredged from channels was often dumped onto the wetlands, from the mid-19th century through the late 20th century, more than a third of the original bay was filled and often built on. The idea was, and remains, controversial, there are five large islands in San Francisco Bay. Alameda, the largest island, was created when a shipping lane was cut in 1901 and it is now predominantly a bedroom community. Angel Island was known as Ellis Island West because it served as the point for immigrants from East Asia. It is now a park accessible by ferry. Mountainous Yerba Buena Island is pierced by a tunnel linking the east and west spans of the San Francisco–Oakland Bay Bridge, attached to the north is the artificial and flat Treasure Island, site of the 1939 Golden Gate International Exposition. From the Second World War until the 1990s, both served as military bases and are now being redeveloped. Isolated in the center of the Bay is Alcatraz, the site of the federal penitentiary. The federal prison on Alcatraz Island no longer functions, but the complex is a popular tourist site, despite its name, Mare Island in the northern part of the bay is a peninsula rather than an island. During the last ice age, the now filled by the bay was a large linear valley with small hills

Ecology of the San Francisco Estuary
–
The San Francisco Estuary together with the Sacramento-San Joaquin River Delta represents a highly altered ecosystem. The region has been heavily re-engineered to accommodate the needs of water delivery, shipping, agriculture and these needs have wrought direct changes in the movement of water and the nature of the landscape, and indirect changes from the introduction of non-native species. New species have altered the architecture of the web as surely as levees have altered the landscape of islands. This article deals particularly with the ecology of the low salinity zone of the estuary, reconstructing a historic food web for the LSZ is difficult for a number of reasons. First, there is no record of the species that historically have occupied the estuary. Climate change, hydrologic engineering, shifting water needs, and newly introduced species will continue to alter the food web configuration of the estuary. This model provides a snapshot of the current state, with notes about recent changes or species introductions that have altered the configuration of the food web. Understanding the dynamics of the current food web may prove useful for restoration efforts to improve the functioning, the San Francisco Bay is both a bay and an estuary. The former term refers to any inlet or cove providing a refuge from the open ocean. An estuary is any physiographic feature where freshwater meets an ocean or sea, the northern portion of the bay is a brackish estuary, consisting of a number of physical embayments which are dominated by both marine and fresh water fluxes. Until the 20th century, the LSZ of the estuary was fringed by tule-dominated freshwater wetlands, between 80-95% of these historic wetlands have been filled to facilitate land use and development around the Bay Area. Habitat loss at the edges of the zone is thought to create a loss of native pelagic fish species. The intertidal and benthic estuary is dominated by mudflats that are largely the result of sedimentation derived from gold mining in the Sierra Nevada in the late 19th century. Thus the mudflats appear to be slowly receding, although turbidity remains extremely high, the high turbidity of the water is responsible for the unique condition that exists in the San Francisco Estuary wherein high nutrient availability does not lead to high phytoplankton production. Instead, most algae photosynthetic organisms are light-limited, the Delta has likewise experienced heavy alteration. Beginning in the 19th century, naturally occurring levees were reinforced for permanency, many of these farms were established on peat islands occurring in the middle of the Delta waterways. Intensive farming oxidized the high content of the soil, causing considerable loss of soil mass. As a consequence, these islands have subsided, or sunk, the Delta today consists of highly riprapped waterways, punctuated by islands that appear like floating bowls with their basins far below the surface of the water

Suisun Bay
–
Suisun Bay is a shallow tidal estuary in northern California. It lies at the confluence of the Sacramento and San Joaquin Rivers, forming the entrance to the Sacramento–San Joaquin River Delta, Suisun Marsh, the tidal marsh land to the north, is the largest marsh in California. Grizzly Bay forms an extension of Suisun Bay. The bay is directly north of Contra Costa County, the bay was named in 1811, after the Suisunes, a Native American tribe of the area. The word originates with the Patwin, on the west, Suisun Bay is drained by the Carquinez Strait, which connects to San Pablo Bay, a northern extension of San Francisco Bay. In addition to the bridges at the Carquinez Strait, it is spanned in its center by the Benicia-Martinez Bridge. It is the anchorage of the Suisun Bay Reserve Fleet, a collection of U. S. Navy and merchant reserve ships, the Glomar Explorer was anchored here after recovering a sunken Soviet submarine in the mid-1970s. Many ships were removed and sold for scrap in the 1990s, in 2010, plans were announced to remove the mothball fleet in stages, with final removal by 2017. The Central Pacific Railroad built a ferry that operated between Benicia and Port Costa, California from 1879 to 1930. The ferry boats Solano and Contra Costa were removed from service when the nearby Martinez railroad bridge was completed in 1930, from 1913 until 1954 the Sacramento Northern Railway, an electrified interurban line, crossed Suisun Bay with the Ramon, a distillate-powered train ferry. Kinder Morgan pleaded guilty to operating a corroded pipeline and paid three dollars in penalties and restitution.

Golden Gate
–
The Golden Gate is a strait on the west coast of North America that connects San Francisco Bay to the Pacific Ocean. It is defined by the headlands of the San Francisco Peninsula and the Marin Peninsula, the strait is well known today for its depth and powerful tidal currents from the Pacific Ocean. Many small whirlpools and eddies can form in its waters, with its strong currents, rocky reefs and fog, the Golden Gate is the site of over 100 shipwrecks. The Golden Gate is often shrouded in fog, especially during the summer, heat generated in the California Central Valley causes air there to rise, creating a low pressure area that pulls in cool, moist air from over the Pacific Ocean. The Golden Gate forms the largest break in the hills of the California Coast Range, allowing a persistent, dense stream of fog to enter the bay there. Before the Europeans arrived in the 18th century, the area around the strait, descendants of both tribes remain in the area. The strait was surprisingly elusive for early European explorers, presumably due to this persistent summer fog. The strait is not recorded in the voyages of Juan Rodríguez Cabrillo nor Francis Drake, the strait is also unrecorded in observations by Spanish galleons returning from the Philippines that laid up in nearby Drakes Bay to the north. These galleons rarely passed east of the Farallon Islands, fearing the possibility of rocks between the islands and the mainland, the first recorded observation of the strait occurred nearly two hundred years later than the earliest European explorations of the coast. Until the 1840s, the strait was called the Boca del Puerto de San Francisco, on 1 July 1846, before the discovery of gold in California, the entrance acquired a new name. Frémont wrote, To this Gate I gave the name of Chrysopylae, or Golden Gate, for the reasons that the harbor of Byzantium was called Chrysoceras. In the 1920s, no bridge spanned the watery expanse between San Francisco and Marin in California—so when the U. S, post Office issued a postage stamp on 1 May 1923, celebrating The Golden Gate, the issue naturally portrayed the scene without a bridge. The Golden Gate Bridge is a bridge spanning the Golden Gate. As part of both US Highway 101 and California Route 1, it connects the city of San Francisco on the tip of the San Francisco Peninsula to Marin County. The Golden Gate Bridge was the longest suspension span in the world when completed in 1937. Since its completion, the length has been surpassed by eight other bridges. It still has the second longest suspension bridge span in the United States. In 2007, it was ranked fifth on the List of Americas Favorite Architecture by the American Institute of Architects, Golden Gate Park, located in San Francisco, California, is a large urban park consisting of 1,017 acres of public grounds
