According to a survey paper written in 1988 about a storm that occurred in 1982 in the Central Valley region, rainstorms that can cause that type of landslide to happen about every 5 years. Landslides to higher degrees, such as the ones that happened due to the 1982 storm, only occur every 20 to 100+ years. This intense storm in the San Francisco Bay area caused

498-419: A lot of damage as a result of moving debris and landslides. They caused damage to the land and put people living in these areas that are susceptible to these disasters in great harm. The aftermath of this storm involved millions of dollars in retributions to restore the land and surrounding areas. It also led people to make greater efforts into planning around the danger of these landslides, as in how to manipulate

581-524: A majority in the county was George H. W. Bush in 1988 . In gubernatorial elections, Sacramento County is typically a bellwether, having voted for the winner every time since 1962 with the exception of 1970 and 2002. In the House of Representatives , all of California's 6th congressional district and portions of its 3rd , and 7th districts are in the county. In the State Assembly , all of

The Sacramento County Department of Transportation (SACDOT) maintains approximately 2200 miles of roadway within the unincorporated area. The roads range from six lane thoroughfares to rural roads. In February 1851, the county was divided into eight civil townships :

1494-505: Is ideal for agriculture. The Central Valley is one of the United States' most productive growing regions. This is made possible by engineering the watercourses to prevent flooding during the spring snowmelt and drying up in the summer and autumn. Many dams, including Shasta Dam , Oroville Dam , Folsom Dam , New Melones Dam , Don Pedro Dam , Hetch Hetchy Dam , Friant Dam , Pine Flat Dam and Isabella Dam , were constructed on

1577-501: Is life-threatening or even fatal. Due to the agricultural industry's significant presence in the Valley, pesticide drift and leaching have become concerns. Residents risk contamination when living in proximity to application sites. Air pollution is a growing problem that affects all of the citizens in the Central Valley. Some reasons of poor air pollution in the Central Valley are due to agriculture and its geographical features. Since

1660-466: Is located partially in unincorporated Sacramento County and partially in the city of Rancho Cordova. Mather Airport is 12 miles east of Downtown Sacramento , on the south side of U.S. Route 50 .  Mather Airport originated as a U.S. Army Air Corp training facility in World War I and was decommissioned as an Air Force base in 1993. It reopened in 1995 as Mather Airport. Sacramento County notes that

1743-403: Is now San Francisco Bay . Over the millennia, the valley filled with the sediments of these same ranges, as well as the rising Sierra Nevada to the east; that filling eventually created an extraordinary flatness just barely above sea level. Before California's flood control and aqueduct system was built, annual snow melt turned much of the valley into an inland sea. The one notable exception to

1909-399: Is released every Thursday, showing which parts of the U.S. are in a drought. It started in 2000, and since then the longest duration of a drought in California lasted a total of 376 weeks. It started on December 11, 2011, and ended on March 5, 2019. The most intense period captured on the drought monitor was on the week of July 29, 2014. It showed that 58.41% of California's land was affected by

1992-607: Is thought to have originated below sea level as an offshore area depressed by subduction of the Farallon Plate into a trench farther offshore. The valley has no earthquake faults of its own but is surrounded by faults to the east and west. The valley was enclosed by the uplift of the Coast Ranges , with its original outlet into Monterey Bay . Faulting moved the Coast Ranges, and a new outlet developed near what

2075-445: Is very hot and dry during the summer and cool and damp in winter when frequent ground fog known regionally as " tule fog " can obscure vision. Summer daytime temperatures frequently surpass 100 °F (38 °C), and common heat waves might bring temperatures exceeding 115 °F (46 °C). Mid-autumn to mid-spring is the rainy season —although during the late summer, southeasterly winds can bring tropical thunderstorms, mainly in

Sacramento International Airport is a major, full-service airport with passenger flights. It is owned by the County of Sacramento. The county also owns Sacramento Mather Airport in Rancho Cordova and Sacramento Executive Airport , both of which are general aviation airports. Sacramento McClellan Airport , formerly McClellan Air Force Base,

2324-510: The Coast Ranges to the west and the Sierra Nevada to the east. The Central Valley is a region known for its agricultural productivity . It provides a large share of the food produced in California. California provides more than half of the fruits, vegetables, and nuts grown in the United States. More than 7,000,000 acres (28,000 km ) of the valley are irrigated via reservoirs and canals. The valley hosts many cities, including

2407-627: The Democratic candidates. Candidates from the Democratic Party have carried the county in the past eight presidential elections, and have won a majority of the county's votes four times during that time (in 2008 , 2012 , 2016 , and 2020 ). The city of Sacramento is strongly Democratic, while rural areas are strongly Republican ; suburban areas are more divided. This pattern is also present in congressional and state legislative elections. The last Republican presidential candidate to win

2490-540: The Golden Gate . Many of the islands lie below sea level because of intensive agriculture, and face a high risk of flooding, which would allow salt water to rush back into the delta, especially when too little fresh water is flowing in from the Valley. The Sacramento River carries far more water than the San Joaquin, with an estimated 22 million acre-feet (27 km ) of virgin annual runoff, as compared to

2573-511: The Mokelumne River and Tuolumne River that run east to west across the middle part of the Central Valley. Most valley lowlands are prone to flooding, especially in the old Tulare Lake , Buena Vista Lake , and Kern Lake rivers. The Kings , Kaweah , Tule and Kern rivers originally flowed into these seasonal lakes, which would expand each spring to flood large parts of the southern San Joaquin Valley. Farms, towns, and infrastructure in these lakebeds are protected with levee systems, while

SaRT and Yolobus both provide bus services connecting Sacramento with Sacramento International Airport . Amtrak and its Amtrak California subsidiary operate passenger rail service from the Sacramento Valley station . This station is served by the Coast Starlight ,

2905-417: The Central Valley consists mostly of farming land, a wide, flat valley, the emissions from the soil that is used for growing produce are released into the air. The soil exudes nitrous oxide , an odorless and colorless gas that can be harmful when exposed to it for a long period of time, and incorporates itself into the ozone layer located at ground level. Production of nitrous oxide in California has shown that

2988-456: The Central Valley produces 8 percent of the nation's agricultural output by value: US$ 43.5 billion in 2013. California's farms and ranches earned almost $ 50 billion in 2018. The valley's productivity relies on irrigation from surface water and badly depleted underground aquifers . About one-sixth of the US' irrigated land is in the Central Valley. Virtually all non-tropical crops are grown in

3071-523: The Central Valley, which cause 312 landslides to move that year. Slow-moving landslides are impacted even if the intensity of the rainfall is not as severe. Consistent, moderately intense rainfall increases the saturation of water in the ground. This over-saturation is what causes the movement of a slow-moving landslide, rather than the more quick-moving and rigorous landslides that also occur in this region of California. Quick-moving landslides are caused by very intense rain, or sometimes earthquakes, that make

3154-405: The Central Valley, which is the primary source for produce throughout the United States, including tomatoes, grapes, cotton, apricots, and asparagus. Six thousand almond growers produced more than 600 million pounds (270 × 10 ^  kg) in 2000, about 70 percent of the world's supply and nearly 100 percent of domestic production. The US' top four counties in agricultural sales are in

3237-569: The Mississippi), Buena Vista Lake and Kern Lake . However, much of the Central Valley environment has been altered by human activity, including the introduction of exotic plants , notably grasses. The valley's grasslands, wetlands, and riparian forests constitute the California Central Valley grasslands , a temperate grasslands, savannas, and shrublands ecoregion . The foothill oak woodlands and chaparral that fringe

3320-695: The Pacific. The waters of the Tulare Basin essentially never reach the ocean (with the exception of Kings River waters diverted northward for irrigation), though they are connected by man-made canals to the San Joaquin. The valley encompasses all or parts of 18 California counties: Butte , Colusa , Glenn , Fresno , Kern , Kings , Madera , Merced , Placer , San Joaquin , Sacramento , Shasta , Stanislaus , Sutter , Tehama , Tulare , Yolo and Yuba . Older names include "the Great Valley",

3486-578: The Sacramento River, 26 percent into the San Joaquin, and 27 percent into Tulare Lake. In the south part of the San Joaquin Valley, the alluvial fan of the Kings River and another from Coast Ranges streams have created a divide. The dry Tulare basin of the Central Valley receives flow from four major Sierra Nevada rivers, the Kings, Kaweah , Tule , and Kern . This basin, usually endorheic , formerly filled during snowmelt and spilled out into

3569-616: The Sacramento Valley for about 447 miles (719 km). In the San Joaquin Valley, the San Joaquin River flows roughly northwest for 365 miles (587 km), picking up tributaries such as the Merced River , Tuolumne River , Stanislaus River and Mokelumne River . The Central Valley watershed encompasses over a third of California at 60,000 square miles (160,000 km ), with 46 percent draining into

3652-576: The Sacramento Valley, with its high year-round flow and wide waterways, has been compared to the small and seasonal rivers of the San Joaquin basin; this also contributes to different identities between the two regions. Subregions and their counties commonly associated with the valley include: The four main population centers in the Central Valley area are roughly equidistant from the next. From south to north, they are Bakersfield , Fresno , Sacramento and Redding . These four cities act as hubs for regional commerce and transportation. The table displays

3735-490: The San Francisco Bay Area. Primary sources of population growth are Bay Area migrants seeking lower housing costs, augmented by immigration from Asia, Central America, Mexico, Ukraine, and the rest of the former Soviet Union. The Central Valley is one of the world's most productive agricultural regions. More than 230 crops are grown there. On less than 1 percent of the total farmland in the United States,

3818-635: The San Joaquin River. Called Tulare Lake , it is usually dry because the rivers feeding it have been diverted for agricultural purposes. Central Valley rivers converge in the Sacramento-San Joaquin Delta , a network of marshy channels, distributaries, and sloughs that wind around islands mainly used for agriculture. There the rivers merge with tidewater, and eventually reach the ocean after passing through Suisun Bay , San Pablo Bay , upper San Francisco Bay , and finally

3901-406: The San Joaquin's approximately 6 million acre-feet (7.4 km ). Intensive agricultural and municipal water consumption decreased the rate of outflow to about 17 million acre-feet (21 km ) for the Sacramento and 3 million acre-feet (3.7 km ) for the San Joaquin. These figures vary widely from year to year. Over 25 million people, living in the valley and other regions of

Sacramento County was politically competitive in most presidential elections between 1976 and 2004, but now votes significantly in favor of

4731-502: The delta. Large blocks of desert scrubland exist in the southern San Joaquin Valley and the Carrizo Plain , just outside the valley, but offering a similar landscape. The wetlands have been the target of rescue operations to restore areas replaced by agriculture. These patches of natural habitat are disconnected, which is particularly damaging for wildlife that is used to migrating along the rivers. Agriculture, grazing land, and

4814-408: The draining of lakes and rivers have radically altered valley habitats. Most of the grassland has been overtaken by new species; most vernal pools have been destroyed, leaving only those on the higher slopes; the marshland has been drained, and the riverbank woodlands have nearly all been affected. The valley gives its name to Valley fever , which is primarily a disease of the lungs that is common in

5146-522: The first significant rainfall. The official season is from November 1 to March 31. This phenomenon is named after the valley's tule grass wetlands ( tulares ). Auto collisions caused by the tule fog are the leading cause of weather-related casualties in California. Two river systems drain and define the two parts of the Central Valley. The Sacramento River , along with its tributaries the Feather River and American River , flows southwards through

5229-491: The flat valley floor is Sutter Buttes , the remnants of an extinct volcano just to the northwest of Yuba City . Another significant geologic feature of the Central Valley lies hidden beneath the delta. The Stockton Arch is an upwarping of the crust beneath the valley sediments that extends southwest to northeast across the valley. The Central Valley lies within the California Trough physiographic section, which

5312-771: The land to accommodate the consequences. Out of the past twenty-two years, California has experienced significant drought conditions for thirteen years. From 2000 to 2018 was the second driest period that California has ever experienced. The driest three-year period ever in California was from 2012 to 2014. Three-quarters of the state of California is experiencing extreme drought conditions. There are also multiple types of droughts such as agricultural droughts, meteorological droughts, snow droughts, and hydrological droughts. All of these droughts affect California in different ways. Droughts can damage forests and can cause wildfires. Droughts cause forests to become dry which causes trees to die. Dead trees result in wildfires. The U.S. drought monitor

5395-497: The other areas in California. The Central Valley is also expanding in the number of people that coincide in that area, so it increases the number of cars which can also contribute to the amount of emission that is in the air. The northern Central Valley has a hot Mediterranean climate ( Köppen climate classification Csa ); the more southerly parts in rainshadow zones are dry enough to be Mediterranean steppe or even low-latitude desert ( BWh , as in areas around Bakersfield ). It

The Government of Sacramento County is defined and authorized under the California Constitution , California law , and the Charter of the County of Sacramento. Much of the Government of California is in practice the responsibility of county governments such as the Government of Sacramento County, while municipalities such as

5644-457: The risk of floods damaging properties increased greatly. The Great Flood of 1862 was the valley's worst flood in recorded history, flooding most of the valley and putting some places as much as 20 feet (6.1 m) under water. In 2003, it was determined that Sacramento had both the least protection against and nearly the highest risk of flooding. Congress then granted a $ 220 million loan for upgrades in Sacramento County. Other counties in

5727-652: The rivers, with many of them being part of the Central Valley Project .

6474-493: The valley that often face flooding are Yuba , Stanislaus , and San Joaquin . There is a very strong positive correlation between rainfall and slow-moving landslides in Northern California, especially in the Central Valley region. Changes in climate and precipitation levels have shown that consistent average rainfall has increased the number and intensity of landslides within the past 5–6 years. This information

6557-597: The valley's native grass habitat , while oak savanna habitats survive near Visalia . Areas of wetland and riverside woodland are found in the north, especially by the Sacramento River system, including the Nature Conservancy 's Cosumnes River Preserve just south of Sacramento, Gray Lodge Wildlife Area, Butte Sink Wildlife Management Area , and other patches in the delta area. Remaining vernal pools include Pixley National Wildlife Refuge between Tulare, California , and Bakersfield and Jepson Prairie Preserve in

6640-403: The “Central Valley”, many residents consider the Central Valley to consist of only the San Joaquin Valley .

6889-456: Was shown in a study that focused on the behavior of these slow-moving landslides and how their nature changed with years of extreme average rainfall versus minimal average rainfall. In 2016, the average annual precipitation levels were lower because of a drought that was coming to an end at that time. The minimal rainfall in that year showed that 119 landslides had been moving. Comparatively, in 2017, there were very extreme levels of precipitation in
