Santa Clarita, California
Santa Clarita the City of Santa Clarita, is the third largest city in Los Angeles County and the 24th largest in the state of California. The city has annexed a number of unincorporated areas, contributing to the large population increase, it is located about 35 miles northwest of downtown Los Angeles, occupies most of the Santa Clarita Valley. It is a notable example of a U. S. edge boomburb. Santa Clarita was ranked by Money magazine in 2006 as 18th of the top 100 places to live. Santa Clarita was incorporated in December 1987 as the union of four unincorporated communities, Canyon Country, Newhall and Valencia, most of which are situated on the land of the former Rancho San Francisco; the four communities retain separate identities, it is common for residents to refer to a specific neighborhood when asked where they are from. Santa Clarita is bounded on the west by the Golden State Freeway; the Antelope Valley Freeway runs northeast-southwest through an irregular east border, the Newhall Pass is the city's southernmost point.
Six Flags Magic Mountain amusement park and Stevenson Ranch are both associated with Santa Clarita, though since both are located west of Interstate 5, neither is within the Santa Clarita city limits. The Santa Clara River was named by Spanish explorers for Clare of Assisi; the valley and the settlement became known as "little Santa Clara" in deference to the Northern California mission and city of Santa Clara, California. In time, "little Santa Clara" became "Santa Clarita." Santa Clarita was incorporated in December 1987. About AD 450, the Tataviam arrived. In 1842, Francisco Lopez made the first "documented" discovery of gold in California; the event is memorialized in an 1842 mining claim issued by Gov. Juan B. Alvarado; the discovery was made in Placerita Canyon, an area used as Hollywood's original back lot. The community of Newhall is named after Henry Newhall, a businessman who made his fortune during the California Gold Rush after opening up the H. M. Newhall & Company, a successful auction house in San Francisco.
Newhall's next business interest was railroads. He invested in rail companies that would connect San Francisco to other cities and became president of the San Francisco and San Jose Railroad. In 1870, he and his partners sold the company to Southern Pacific Railroad, on whose board of directors he sat. After railroads, Newhall turned to real ranching, he purchased a number of the old Spanish and Mexican land grants in the state for a total of 143,000 acres between Monterey and Los Angeles counties. The most significant portion was the 46,460 acres Rancho San Francisco in northern Los Angeles County, which he purchased for $2/acre, which became known as Newhall Ranch after Newhall's death. Within this territory, he granted a right-of-way to Southern Pacific through what is now Newhall Pass, he sold them part of the land, upon which the company built a town named after him: Newhall; the first station built on the line he named for his hometown, Massachusetts. After his death, Newhall's heirs incorporated the Newhall Land and Farming Company, which oversaw the development of the communities that now make up Santa Clarita.
On September 26, 1876, Charles Alexander Mentry brought in the state's first productive oil well at Mentryville, giving rise to the California oil industry. The oil was brought to a refinery at Newhall, now the oldest existing petroleum refinery in the world. A few days earlier, on September 5, 1876, Charles Crocker and Leland Stanford joined their railroads in Canyon Country, linking Los Angeles with the rest of the nation for the first time; the Saugus Cafe, on Railroad Avenue in Saugus, was established in 1887 and appears to be, by far, the oldest still-operating restaurant in Los Angeles County. Filming in Santa Clarita began shortly after the turn of the 20th century with a veritable Who's Who of actors, including William S. Hart, Tom Mix, Harry Carey and a young John Wayne. Hart and Carey made their homes in the Santa Clarita Valley; the Santa Clarita Valley was the scene of the second worst disaster in California's history in terms of lives lost, known as the "worst civil engineering failure of the 20th century".
Shortly before midnight on March 12, 1928, the St. Francis Dam collapsed. By the time the floodwaters reached the Pacific Ocean near Ventura five hours nearly 600 people were dead. Within modern Santa Clarita city limits, the present day site of the Westfield Valencia Town Center mall would have been buried beneath muck and debris; some buildings in Newhall became makeshift morgues. After multiple failed attempts to form a city and at least two failed attempts to form a separate county, the people of the Santa Clarita Valley incorporated the City of Santa Clarita at 4:30 PM on December 15, 1987 after voting in favor of incorporation by a margin of two to one in that year's general election; the other proposed name for the new city, narrowly defeated, was "City of the Canyons." Santa Clarita, according to the United States Census Bureau, has an area of 62.16 square miles, of which 62.10 square miles is land and 0.06 square miles is water. Santa Clarita is near the San Fernando fault zone and was affected by the 1971 San Fernando earthquake known as the Sylmar quake.
The city was affected by the 1994 Northridge earthquake, many commercial and residential buildings were devastated by its aftermath, including the nearby Newhall Pass, the Valencia Town Center, Six Flags Magic Mountain. Magi
Pasadena is a city in Los Angeles County, United States, located 10 miles northeast of Downtown Los Angeles. The estimated population of Pasadena was 142,647 in 2017, making it the 183rd-largest city in the United States. Pasadena is the ninth-largest city in Los Angeles County. Pasadena was incorporated on June 19, 1886, becoming one of the first cities to be incorporated in what is now Los Angeles County, following the city of Los Angeles, it is one of the primary cultural centers of the San Gabriel Valley. The city is known for hosting Tournament of Roses Parade. In addition, Pasadena is home to many scientific and cultural institutions, including Caltech, Pasadena City College, Fuller Theological Seminary, ArtCenter College of Design, the Pasadena Playhouse, the Ambassador Auditorium, the Norton Simon Museum, the USC Pacific Asia Museum; the original inhabitants of Pasadena and surrounding areas were members of the Native American Hahamog-na tribe, a branch of the Tongva Nation. They had lived in the Los Angeles Basin for thousands of years.
Tongva dwellings lined the Arroyo Seco in present day Pasadena and south to where it joins the Los Angeles River and along other natural waterways in the city. The native people lived in dome-shape lodges, they lived on a diet of acorn meal and herbs, other small animals. They traded for ocean fish with the coastal Tongva, they made cooking vessels from steatite soapstone from Catalina Island. The oldest transportation route still in existence in Pasadena is the old Tongva foot trail known as the Gabrielino Trail, that follows the west side of the Rose Bowl and the Arroyo Seco past the Jet Propulsion Laboratory into the San Gabriel Mountains; the trail has been in continuous use for thousands of years. An arm of the trail is still in use in what is now known as Salvia Canyon; when the Spanish occupied the Los Angeles Basin they built the San Gabriel Mission and renamed the local Tongva people "Gabrielino Indians," after the name of the mission. Today, several bands of Tongva people live in the Los Angeles area.
Pasadena is a part of the original Mexican land grant named Rancho del Rincon de San Pascual, so named because it was deeded on Easter Sunday to Eulalia Perez de Guillén Mariné of Mission San Gabriel Arcángel. The Rancho comprised the lands of today's communities of Pasadena and South Pasadena. Before the annexation of California in 1848, the last of the Mexican owners was Manuel Garfias who retained title to the property after statehood in 1850. Garfias sold sections of the property to the first Anglo settlers to come into the area: Dr. Benjamin Eaton, the father of Fred Eaton. Much of the property was purchased by Benjamin Wilson, who established his Lake Vineyard property in the vicinity. Wilson, known as Don Benito to the local Indians owned the Rancho Jurupa and was mayor of Los Angeles, he was the grandfather of Jr. and the namesake of Mount Wilson. In 1873, Wilson was visited by Dr. Daniel M. Berry of Indiana, looking for a place in the country that could offer a mild climate for his patients, most of whom suffered from respiratory ailments.
Berry claimed that he had his best three night's sleep at Rancho San Pascual. To keep the find a secret, Berry code-named the area "Muscat" after the grape. To raise funds to bring the company of people to San Pascual, Berry formed the Southern California Orange and Citrus Growers Association and sold stock in it; the newcomers were able to purchase a large portion of the property along the Arroyo Seco and on January 31, 1874, they incorporated the Indiana Colony. As a gesture of good will, Wilson added 2,000 acres of then-useless highland property, part of which would become Altadena. Colonel Jabez Banbury opened the first school on South Orange Grove Avenue. Banbury had twin daughters, named Jessie; the two became the first students to attended Pasadena’s first school on Orange Grove. At the time, the Indiana Colony was a narrow strip of land between the Arroyo Seco and Fair Oaks Avenue. On the other side of the street was Wilson's Lake Vineyard development. After more than a decade of parallel development on both sides, the two settlements merged into the City of Pasadena.
The popularity of the region drew people from across the country, Pasadena became a stop on the Atchison and Santa Fe Railway, which led to an explosion in growth. From the real estate boom of the 1880s until the Great Depression, as great tourist hotels were developed in the city, Pasadena became a winter resort for wealthy Easterners, spurring the development of new neighborhoods and business districts, increased road and transit connections with Los Angeles, culminating with the opening of the Arroyo Seco Parkway, California's first freeway. By 1940, Pasadena had become the eighth-largest city in California and was considered a twin city to Los Angeles; the first of the great hotels to be established in Pasadena was the Raymond atop Bacon Hill, renamed Raymond Hill after construction. Pasadena was served by the Atchison and Santa Fe Railway at the Santa Fe Depot in downtown when the Second District was opened in 1887; the original Mansard Victorian 200-room facility burned down on Easter morning of 1895, was rebuilt in 1903, razed during the Great Depression to make way for residential development.
The Maryland Hotel existed from the early 1900s and was demolished in 1934. The world-famous Mount Lowe Railway and associated mountain hotels shu
2010 United States Census
The 2010 United States Census is the twenty-third and most recent United States national census. National Census Day, the reference day used for the census, was April 1, 2010; the census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired; the population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 Census. This was the first census in which all states recorded a population of over half a million, as well as the first in which all 100 largest cities recorded populations of over 200,000; as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed. Participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25, 2010, Census Bureau Director Robert Groves inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, a resident of Noorvik, Alaska.
More than 120 million census forms were delivered by the U. S. Post Office beginning March 15, 2010; the number of forms mailed out or hand-delivered by the Census Bureau was 134 million on April 1, 2010. Although the questionnaire used April 1, 2010 as the reference date as to where a person was living, an insert dated March 15, 2010 included the following printed in bold type: "Please complete and mail back the enclosed census form today." The 2010 Census national mail participation rate was 74%. From April through July 2010, census takers visited households that did not return a form, an operation called "non-response follow-up". In December 2010, the U. S. Census Bureau delivered population information to the U. S. President for apportionment, in March 2011, complete redistricting data was delivered to states. Identifiable information will be available in 2082; the Census Bureau did not use a long form for the 2010 Census. In several previous censuses, one in six households received this long form, which asked for detailed social and economic information.
The 2010 Census used only a short form asking ten basic questions: How many people were living or staying in this house, apartment, or mobile home on April 1, 2010? Were there any additional people staying here on April 1, 2010 that you did not include in Question 1? Mark all that apply: Is this house, apartment, or mobile home – What is your telephone number? What is Person 1's name? What is Person 1's sex? What is Person 1's age and Person 1's date of birth? Is Person 1 of Hispanic, Latino, or Spanish origin? What is Person 1's race? Does Person 1 sometimes live or stay somewhere else? The form included space to repeat all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, nor was the form available for download. Detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey; the survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years.
A small percentage of the population on a rotating basis will receive the survey each year, no household will receive it more than once every five years. In June 2009, the U. S. Census Bureau announced. However, the final form did not contain a separate "same-sex married couple" option; when noting the relationship between household members, same-sex couples who are married could mark their spouses as being "Husband or wife", the same response given by opposite-sex married couples. An "unmarried partner" option was available for couples; the 2010 census cost $13 billion $42 per capita. Operational costs were $5.4 billion under the $7 billion budget. In December 2010 the Government Accountability Office noted that the cost of conducting the census has doubled each decade since 1970. In a detailed 2004 report to Congress, the GAO called on the Census Bureau to address cost and design issues, at that time, had estimated the 2010 Census cost to be $11 billion. In August 2010, Commerce Secretary Gary Locke announced that the census operational costs came in under budget.
Locke credited the management practices of Census Bureau director Robert Groves, citing in particular the decision to buy additional advertising in locations where responses lagged, which improved the overall response rate. The agency has begun to rely more on questioning neighbors or other reliable third parties when a person could not be reached at home, which reduced the cost of follow-up visits.

Los Angeles County Sheriff's Department
With 18,000 employees, the Los Angeles County Sheriff's Department the County of Los Angeles Sheriff's Department, is the nation's largest sheriff's department. The department's three main responsibilities entail providing patrol services for 153 unincorporated communities of Los Angeles County, California and 42 cities, providing courthouse security for the Superior Court of Los Angeles County, the housing and transportation of inmates within the county jail system. In addition, the department contracts with the Los Angeles Metropolitan Transportation Authority and Metrolink, provides law enforcement services to ten community colleges, patrols over 177 county parks, golf courses, special event venues, two major lakes, 16 hospitals, over 300 county facilities; the Los Angeles County Sheriff's Department's transit division alone is the second largest transit police force in the world, aside from the New York City Police Department. This is through policing contracts of the Metro trains and buses of the Los Angeles Metro and Metrolink.
Furthermore, with policing contracts with nine campuses of the Los Angeles Community College and Lancaster Community College District, the LASD is the largest community policing agency in the United States.

A census is the procedure of systematically acquiring and recording information about the members of a given population. The term is used in connection with national population and housing censuses; the United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory and defined periodicity", recommends that population censuses be taken at least every 10 years. United Nations recommendations cover census topics to be collected, official definitions and other useful information to co-ordinate international practice; the word is of Latin origin: during the Roman Republic, the census was a list that kept track of all adult males fit for military service. The modern census is essential to international comparisons of any kind of statistics, censuses collect data on many attributes of a population, not just how many people there are. Censuses began as the only method of collecting national demographic data, are now part of a larger system of different surveys.
Although population estimates remain an important function of a census, including the geographic distribution of the population, statistics can be produced about combinations of attributes e.g. education by age and sex in different regions. Current administrative data systems allow for other approaches to enumeration with the same level of detail but raise concerns about privacy and the possibility of biasing estimates. A census can be contrasted with sampling in which information is obtained only from a subset of a population. Modern census data are used for research, business marketing, planning, as a baseline for designing sample surveys by providing a sampling frame such as an address register. Census counts are necessary to adjust samples to be representative of a population by weighting them as is common in opinion polling. Stratification requires knowledge of the relative sizes of different population strata which can be derived from census enumerations. In some countries, the census provides the official counts used to apportion the number of elected representatives to regions.
In many cases, a chosen random sample can provide more accurate information than attempts to get a population census. A census is construed as the opposite of a sample as its intent is to count everyone in a population rather than a fraction. However, population censuses rely on a sampling frame to count the population; this is the only way to be sure that everyone has been included as otherwise those not responding would not be followed up on and individuals could be missed. The fundamental premise of a census is that the population is not known and a new estimate is to be made by the analysis of primary data; the use of a sampling frame is counterintuitive as it suggests that the population size is known. However, a census is used to collect attribute data on the individuals in the nation; this process of sampling marks the difference between historical census, a house to house process or the product of an imperial decree, the modern statistical project. The sampling frame used by census is always an address register.
Thus it is not known how many people there are in each household. Depending on the mode of enumeration, a form is sent to the householder, an enumerator calls, or administrative records for the dwelling are accessed; as a preliminary to the dispatch of forms, census workers will check any address problems on the ground. While it may seem straightforward to use the postal service file for this purpose, this can be out of date and some dwellings may contain a number of independent households. A particular problem is what are termed'communal establishments' which category includes student residences, religious orders, homes for the elderly, people in prisons etc; as these are not enumerated by a single householder, they are treated differently and visited by special teams of census workers to ensure they are classified appropriately. Individuals are counted within households and information is collected about the household structure and the housing. For this reason international documents refer to censuses of housing.
The census response is made by a household, indicating details of individuals resident there. An important aspect of census enumerations is determining which individuals can be counted from which cannot be counted. Broadly, three definitions can be used: de facto residence; this is important to consider individuals who have temporary addresses. Every person should be identified uniquely as resident in one place but where they happen to be on Census Day, their de facto residence, may not be the best place to count them. Where an individual uses services may be more useful and this is at their usual, or de jure, residence. An individual may be represented at a permanent address a family home for students or long term migrants, it is necessary to have a precise definition of residence to decide whether visitors to a country should be included in the population count. This is becoming more important as students travel abroad for education for a period of several years. Other groups causing problems of enumeration are new born babies, people away on holiday, people moving home around census day, people without a fixed address.
People having second homes because of working in another part of the country or retaining a holiday cottage are dif
Lake Elsinore is a natural freshwater lake in Riverside County, located east of the Santa Ana Mountains and fed by the San Jacinto River. Named Laguna Grande by Spanish explorers, it was renamed for the town of Elsinore, now Lake Elsinore, established on its northeastern shore on April 9, 1888. Lake Elsinore is the largest natural freshwater lake in Southern California. With its own 750-mi2 watershed, it is situated at the lowest point within the San Jacinto River watershed of 750 sq mi, at the terminus of the San Jacinto River, it is the terminal lake of a closed basin called the San Jacinto Basin. Lake levels are healthy at an average of 1,244 ft above sea level with a volume of 30,000 acre⋅ft that fluctuates, although much has been done to prevent the lake from drying up, flooding, or becoming stagnant. At 1,255 ft, the lake will spill into the outflow channel on its northeastern shore, known properly as Temescal Wash, flowing northwest through Temescal Canyon and feeding Alberhill Creek, which joins Temescal Creek, which in turn dumps into the Santa Ana River just northwest of Corona.
Lake Elsinore was seen by the Spanish Franciscan padre Juan Santiago, exploring eastward from the Mission San Juan Capistrano in 1797. In 1810, the water level of the Laguna Grande was first described by a traveler as being little more than a swamp about a mile long. In the early 19th century, the lake grew larger, providing Mexican rancheros, American trappers, the expedition of John C. Frémont, the immigrants during the California Gold Rush a spot to camp and water their animals as they traveled along the southern shore of the lake on what became the Southern Emigrant Trail and the route of the Butterfield Overland Mail; the lake and the Laguna Rancho adobe built near the lake on its southwest shore at its western corner was described by Benjamin Ignatius Hayes, who stayed there overnight on January 27–28, 1850: In about 15 miles reach some timber where the hills approach near the termination of the valley of Temecula, a sort of low divide over which we enter into another valley. In both these is much good soil, although in the latter more of the wiry grass and more marshy, some little evergreen oak among the hills.
Come to the Laguna, two miles from the divide. Some good young grass, great deal of elder on its banks; the water of the Laguna is saltish, the animals cannot drink it. As we were moving along the lake, an Indian overtook us. At sunset the moon is reflected on the lake. Wild sage. How is it supplied with water? Clover around it; the house is a substantial adobe. A small stream seems to enter it on the east. A low range of hills nearly surrounds the lake, higher; the lake valley seems to be higher than that of Temecula. …Two or three men at this house. Road firm and good ascending for a mile or more from the lake; as a result of the Great Flood of 1862, the level of the lake was high, the Union Army created a post at the lake to graze and water their horses. In the great 1862–65 drought, most of the cattle in Southern California died and the lake level fell during 1866 and 1867, when no rain fell. However, the lake was full again in 1872, when it overflowed down its outlet through Temescal Canyon. After 1872, the lake again evaporated to a low level, but the great rains in the winter of 1883–84 filled it to overflowing in three weeks.
Descriptions of the lake at this time say that large willow trees surrounding the former low-water shore line stood 20 ft or more below the high-water level and were of such size that they must have been 30 or more years old. This indicated the high water of the 1860s and 1870s must have been of a short duration; the rainfall until 1893 was greater than normal, the lake remained high and overflowed on three or four occasions during that time. The lake water was purchased by the Temescal Water Company for the irrigation of land in Corona, California, its outlet channel was deepened, permitting gravity flow down the natural channel of Temescal Canyon to Corona for a year or more after the water level sank below the natural elevation of its outlet. As the lake surface continued to recede, a pumping plant was installed, pumping was continued a few seasons, but the concentration of salts in the lake, due to the evaporation and lack of rainfall, soon made the water unfit for irrigation, the project was abandoned by the company.
After 1893, the lake's water level sank continuously for nearly 10 years, with a slight rise every winter. Heavier precipitation, beginning in 1903 filled the lake to about half the depth above its minimum level since 1883. In January, 1916, a flood raised the level to overflowing; the lake hosted teams for Olympic training and high-speed boat racing in the 1920s. The lake went dry in the mid-1930s, but refilled by 1938; the lake was refilled in the early 1960s. More than a week of heavy rains in 1980 flooded the lake, destroying surrounding homes and businesses. Since a multimillion-dollar project has been put into place to
Alta California, known sometimes unofficially as Nueva California, California Septentrional, California del Norte or California Superior, began in 1804 as a province of New Spain. Along with the Baja California peninsula, it had comprised the province of Las Californias, but was split off into a separate province in 1804. Following the Mexican War of Independence, it became a territory of Mexico in April 1822 and was renamed "Alta California" in 1824; the claimed territory included all of the modern US states of California and Utah, parts of Arizona, Wyoming and New Mexico. Neither Spain nor Mexico colonized the area beyond the southern and central coastal areas of present-day California, small areas of present-day Arizona, so they exerted no effective control in modern-day California north of the Sonoma area, or east of the California Coast Ranges. Most interior areas such as the Central Valley and the deserts of California remained in de facto possession of indigenous peoples until in the Mexican era when more inland land grants were made, after 1841 when overland immigrants from the United States began to settle inland areas.
Large areas east of the Sierra Nevada and Coast Ranges were claimed to be part of Alta California, but were never colonized. To the southeast, beyond the deserts and the Colorado River, lay the Spanish settlements in Arizona. Alta California ceased to exist as an administrative division separate from Baja California in 1836, when the Siete Leyes constitutional reforms in Mexico re-established Las Californias as a unified department, granting it more autonomy. Most of the areas comprising Alta California were ceded to the United States in the Treaty of Guadalupe Hidalgo that ended the Mexican–American War in 1848. Two years California joined the union as the 31st state. Other parts of Alta California became all or part of the U. S. states of Arizona, Utah and Wyoming. The Spanish explored the coastal area of Alta California by sea beginning in the 16th century and prospected the area as a domain of the Spanish monarchy. During the following two centuries there were various plans to settle the area, including Sebastián Vizcaíno's expedition in 1602–03 preparatory to colonization planned for 1606–07, canceled in 1608.
Between 1683 and 1834, Jesuit and Franciscan missionaries established a series of religious outposts from today's Baja California and Baja California Sur into present-day California. Father Eusebio Kino missionized the Pimería Alta from 1687 until his death in 1711. Plans in 1715 by Juan Manuel de Oliván Rebolledo resulted in a 1716 decree for extension of the conquest which came to nothing. Juan Bautista de Anssa proposed an expedition from Sonora in 1737 and the Council of the Indies planned settlements in 1744. Don Fernando Sánchez Salvador researched the earlier proposals and suggested the area of the Gila and Colorado Rivers as the locale for forts or presidios preventing the French or the English from "occupying Monterey and invading the neighboring coasts of California which are at the mouth of the Carmel River." Alta California was not accessible from New Spain: land routes were cut off by deserts and hostile Native populations and sea routes ran counter to the southerly currents of the distant northeastern Pacific.
New Spain did not have the economic resources nor population to settle such a far northern outpost. Spanish interest in colonizing Alta California was revived under the visita of José de Gálvez as part of his plans to reorganize the governance of the Interior Provinces and push Spanish settlement further north. In subsequent decades, news of Russian colonization and maritime fur trading in Alaska, the 1768 naval expedition of Pyotr Krenitsyn and Mikhail Levashev, in particular, alarmed the Spanish government and served to justify Gálvez's vision. To ascertain the Russian threat, a number of Spanish expeditions to the Pacific Northwest were launched. In preparation for settlement of Alta California, the northern, mainland region of Las Californias was granted to Franciscan missionaries to convert the Native population to Catholicism, following a model, used for over a century in Baja California; the Spanish Crown funded the construction and subsidized the operation of the missions, with the goal that the relocation and enforced labor of Native people would bolster Spanish rule.
The first Alta California mission and presidio were established by the Franciscan friar Junípero Serra and Gaspar de Portolá in San Diego in 1769. The following year, 1770, the second mission and presidio were founded in Monterey. In 1773 a boundary between the Baja California missions and the Franciscan missions of Alta California was set by Francisco Palóu; the missionary effort coincided with the construction of presidios and pueblos, which were to be manned and populated by Hispanic people. The first pueblo founded was San José in 1777, followed by Los Ángeles in 1781. By law, mission land and property were to pass to the indigenous population after a period of about ten years, when the natives would become Spanish subjects. In the interim period, the Franciscans were to act as mission administrators who held the land in trust for the Native residents; the Franciscans, prolonged their control over the missions after control of Alta California passed from Spain to independent Mexico, continued to run the missions until they were secularized, beginning in 1833.
The transfer of property never occurr
