San Luis Obispo (pron.: / /; Spanish for St. Louis, the Bishop of Toulouse) is a city in California, located roughly midway between Los Angeles and San Francisco on the Central Coast. Founded in 1772 by Spanish Fr. Junípero Serra, San Luis Obispo is one of California's oldest communities. The city, locally referred to as San Luis, SLO, or SLO Town (as its county is also referred to as SLO) is the county seat of San Luis Obispo County and is adjacent to California Polytechnic State University. The population was 45,119 at the 2010 census. The population of San Luis Obispo County was 269,637 in 2010.
The earliest human inhabitants of the local area were the Chumash peoples. One of the earliest villages lies south of San Luis Obispo and reflects the landscape of the early Holocene when estuaries came farther inland. These Chumash people exploited marine resources of the inlets and bays along the Central Coast and inhabited a network of villages including sites at Los Osos and Morro Creek.
During the Spanish Empire expansion throughout the world, specifically in 1769, Spanish Franciscan Junípero Serra received orders from Spain to bring the Catholic faith to the Natives of Alta California; the idea was to unify the empire under the same religion and language. Mission San Diego was the first Spanish mission founded in Alta California that same year.
On September 7–8, 1769, Gaspar de Portolà traveled through the San Luis Obispo area on his way to rediscover the Monterey Bay. The expedition's diarist, Padre Juan Crespí, recorded the name given to this area by the soldiers as llano de los Osos, or the level of the bears (Bear Plain), as this was an area with an abundance of bears. Since then, various translations of the Crespí Diary have called this area La Cañada de Los Osos (The track of the Bears) which has been further mistranslated as the Valley of the Bears. In 1770, Junípero Serra founded the second mission, San Carlos Borromeo, in Monterey which was moved to Carmel the following year. As supplies dwindled in 1772 at the then-four missions, the people faced starvation. Remembering the Valley of the Bears, a hunting expedition was sent to bring back food in the summer of 1772. Over twenty-five mule loads of dried bear meat and seed was sent north to relieve the missionaries, soldiers, and neophytes (baptized Natives). The Natives were impressed at the ease by which the Spaniards could take down the huge grizzlies with their weapons. Some of the meat was traded with the local people in exchange for edible seed. It was after this that Junípero Serra decided that La Cañada de Los Osos would be an ideal place for the fifth mission. The area had abundant supplies of food and water, the climate was also very mild, and the local Chumash were very friendly. With soldiers, muleteers, and pack animals carrying mission supplies, Junípero Serra set out on a journey to reach the Valley of the Bears. On September 1, 1772, Junípero Serra celebrated the first Mass with a cross erected near San Luis Creek. The very next day, he departed for San Diego leaving Fr. José Cavaller, with the difficult task of building the mission. Fr. José Cavaller, five soldiers and two neophytes began building what is today called Mission San Luis Obispo de Tolosa and would become later the town of San Luis Obispo.
After Junípero Serra left, the difficult task of actually building the mission remained. The mission was built with adobe and tile structures. The mission included: the church, the priest's residence, the convento, the storerooms, residences for single women and families from Spain, soldiers' barracks, and mills. The mission also had land for farming and raising livestock, as the whole community of priests, Natives and soldiers needed to produce goods for their own livelihood.
When the Mexican War of Independence from Spain broke out in 1810, all California missions were virtually self-sufficient, receiving few funds from Spain.
With the independence from Spain there was little left of the thriving community of earlier times. Soon after Mexico won her independence from Spain (1821), the Missions were secularized by the Mexican government. However, the community remained in the same location of what is today San Luis Obispo.
San Luis Obispo once had a burgeoning Chinatown in the vicinity of Palm St. and Chorro St. Laborers were brought from China by Ah Louis in order to construct the Pacific Coast Railway, roads connecting San Luis Obispo to Paso Robles and Paso Robles to Cambria, and also the 1884 to 1894 tunneling through Cuesta Ridge for the Southern Pacific Railroad. The town's Chinatown revolved around Ah Louis Store and other Palm Street businesses owned and run by Chinese business people. Today, Mee Heng Low chop suey shop is all that remains of the culture, although a slightly Chinatown-themed commercial development is being planned. A display of some of the unearthed relics from this period can be seen on the first floor of the Palm Street parking garage, which was built over the location where Chinatown once stood. The San Luis Obispo Historical Society (adjacent to the Mission) also contains rotating historical exhibits.
San Luis Obispo was also a popular stop on both U.S. Route 101 and California State Route 1 with the rise of car culture. Due to its popularity as a stop, it was the location of the first motel, the Milestone Mo-Tel.
Among San Luis Obispo's historical buildings is the former San Luis Obispo Carnegie Library, located at 696 Monterey Street. The San Luis Obispo Carnegie Library was built in 1905 with a grant of $10,000 from Andrew Carnegie, who funded the establishment of 142 California libraries in the early 1900s. The Romanesque style building was designed by architect W. H. Weeks of Watsonville, California and was built by contractor Joseph Maino of San Luis Obispo. As one of numerous California public buildings designed by W. H. Weeks, it shares features with Carnegie libraries in nearby Lompoc and Paso Robles. The San Luis Obispo Carnegie building served as the city library until 1955, when a new public library was built at the corner of Palm and Morro Streets. It has been home to the San Luis Obispo County Historical Museum since 1956. The Carnegie Library building is listed on the National Register of Historic Places.
San Luis Obispo's largest and oldest voluntary organization is the San Luis Obispo Chamber of Commerce, which also is the oldest and largest voluntary organization in San Luis Obispo County.

These mountains are the headwaters for San Luis Obispo Creek, whose watershed encompasses 84 square miles (220 km2) surrounding the city and flows to the Pacific Ocean at Avila Beach.
San Luis Obispo is a seismically active area; there are a number of nearby faults including the San Andreas Fault. The Nine Sisters are a string of hills that partially run through San Luis Obispo. They are geologically noteworthy for being volcanic plugs. Six of the nine peaks are open to the public for recreation.
San Luis Obispo experiences a cool Mediterranean climate (Köppen climate classification Csb). On average it has 50 days with measurable rain per year – mostly during winter months. Summers are generally warm and sunny, often with morning fog from the Pacific coast. Winters are generally mild, though below freezing lows may be expected 4 nights per year. Temperatures do, however, vary widely at any time of the year, with 80 °F (27 °C) readings in January and February not uncommon. Storms of any kind are rare (although in October 2009 an unusually powerful early-season storm drenched the city with nearly 8 inches (200 mm) of rain).

Notable ordinances 
In June 1990 City Councilman Jerry Reiss proposed a city ordinance to ban smoking in all indoor public areas. Following a failed effort by R. J. Reynolds Tobacco Company to defeat the ordinance, the City Council voted 4–1 in favor on June 19, 1990 with only Mayor Ron Dunin dissenting. As a result, on August 2, 1990, San Luis Obispo became the first municipality in the world to ban smoking in all public buildings, including bars and restaurants. This statute has been a catalyst worldwide in anti-smoking legislation. In April, 2010, San Luis Obispo strengthened its anti-smoking legislation, making smoking in public, excepting for certain conditions, a citable offense beginning on June 20, 2010.
In 1982, following public hearings, the City Council approved an ordinance forbidding the construction of "drive-through" businesses. In-N-Out Burger opened a restaurant in the nearby town of Atascadero because of the ban. In 2008 the City Council voted 3–2 to keep the ban.
In 1982 a city ordinance was passed that prohibited the sale of alcoholic beverages at any business selling gasoline, with the exception of one Mobil (now Union 76) service station on South Higuera Street that was grandfathered in prior to the ordinance. The city council voted 3–2 to abolish the ordinance in 2004.
In April 2010, an "unruly gathering" ordinance passed with a vote of 4–1. This ordinance poses a fine of $700 for the hosts of gatherings with more than 20 people on private property which create a substantial disturbance in a significant amount of the neighborhood. Unlawful conduct includes excessive noise; public drunkenness; serving alcohol to minors; fighting; urinating in public; crowds overflowing into yards, sidewalks, or streets; or similar unlawful behaviors.

U.S. Route 101 and California State Route 1 are the major north-south highways in San Luis Obispo, linking the city to the rest of the Central Coast region, San Francisco to the north, and Los Angeles to the south. Both enter the city from the south as a concurrency. As they head north, Highway 1 then splits towards the coast to Morro Bay, while Highway 101 stays more inland to Paso Robles. California State Route 227 provides an alternate route to Highway 101 from San Luis Obispo south to Arroyo Grande.
Bicycling is increasing as a mode of transportation. The Bill Roalman (Morro Street) Bicycle Boulevard gives priority to bicycle traffic while a special bicycle traffic signal (one of only a handful in the United States) allows bicyclists their own phase in traffic flow. The SLO County Bicycle Coalition offers a free bicycle valet service during the weekly Farmers' Market. In 2007, the city was designated as a Bicycle Friendly Community at the Silver level by the League of American Bicyclists.
The city provides parking in three multistory parking structures downtown . Street parking downtown is metered except on Sundays and holidays. The city's innovative Racks with Plaques program has increased bike racks in the downtown area and has cut down on parking congestion.
The Madonna Inn is a famous local landmark. Established by Alex Madonna in 1958, the inn is famously eccentric. The Fremont Theater, a historic Art Deco theater from the 1940s, still plays first run movies on the huge screen. Murals adorn the walls of the main theater while neon swirls light the ceiling. The Palm Theatre boasts solar heating and is home to the San Luis Obispo International Film Festival. Another destination is Bubblegum Alley. Since about 1960, people have been sticking chewed gum on the walls of this alley. The doctor's office on the corner of Santa Rosa and Pacific streets is one of very few commercial buildings designed by Frank Lloyd Wright. San Luis also has a Carnegie Library which is now home to the San Luis Obispo County Historical Museum.
Lots of mystery surrounds the "underground city", or the series of tunnels that exists beneath the city.
One of the largest Mardi Gras parades West of the Mississippi used to be held in San Luis Obispo, but it has been canceled recently because of difficulties related to crowd control and alcohol consumption.
Cal Poly's open house, Poly Royal, was held annually from 1933 to 1990. It was canceled in 1945 due to war rationing. It began as a show-and-tell for students to display their projects. It traces its origins to the 1904 Farmer's Institute and Picnic Basket. By the 1980s, as the college became "the most popular...university in the 19-campus CSU system", Poly Royal began drawing over 100,000 people from throughout the state, including 126,000 people in 1985. Concerts, parties, and other entertainment were added and it earned $3–4 million in revenue for the city every year.
Following a "mini-riot" in 1989 at an off-campus apartment during Poly Royal, the events in 1990 would cancel the event "indefinitely." Two nights of rioting on April 28–29 led to 127 arrests, over 100 injuries and 14 police injuries on top of "several hundred thousand dollars" worth of damage. A liquor store near campus, Campus Bottle, was destroyed by revelers demanding alcohol. The second night was much larger than the first as people were leaving a concert on campus and parties off-campus were broken up and revelers flooded the streets. Mayor Dunin called the events "the worst experience in the history of San Luis Obispo." After a meeting between Mayor Dunin and University President Warren Baker the following Monday, Poly Royal was canceled from that point forward. The name Poly Royal returned in 2001 as "Open House Presents Poly Royal", a scaled down version that was designed for students and parents.
San Luis Obispo has been home of several other events, including a stop on the way of the Olympic Flame Relay, the Tour of California bicycle race, Cinco de Mayo celebrations, an annual Mozart festival, held every July, and a long-standing Christmas Parade. Another attraction is the development of Edna Valley into a well-known wine region. Just south of the city, people can spend an afternoon wine tasting several wineries in the area with a very short drive. The wine region extends north beyond Paso Robles (30 miles north) and south to Santa Ynez (70 miles south).
During Summer months, local residents and visitors congregate in the Mission Plaza for a free outdoor concert every Friday evening. The event is called Concerts in the Plaza. Other noteworthy events include the San Luis Obispo International Film Festival, Festival Mosaic, and the Plein Air Festival.
San Luis Obispo hosts a Farmer's Market every Thursday night from 6-9PM on Higuera Street, between Osos and Nipomo Streets. During this weekly event, the street is closed to vehicle traffic while vendors sell food and goods and various visual and music artists perform for the crowds.
Since June 2000, the first Thursday of every month is The Bike Happening (also known as Bike Nite) in San Luis Obispo. People gather after the Farmer's Market at the Mission Plaza with their bikes. The bikers then go around on multiple circuits on the main streets of downtown adhering to the traffic laws (for the most part). The ride is considered a fun/social ride meant to encourage people to get back on their bikes and to have fun. Each Bike Happening has a theme and a large portion of the crowd is in some costume adherent to the theme.
One of the cultural focal centers of San Luis Obispo is the Christopher Cohen Performing Arts Center built on the Cal Poly Campus, which was constructed utilizing the donations of local businesses and individuals. The Performing Arts Center consists of multiple venues, including the original Spanos Theatre. The largest venue, Harmon Hall, seats 1,300. Many high school and college programs are scheduled. Local artists perform plays, music and dance. The addition of the Performing Arts Center attracts many touring performances which are usually not found in communities of comparable size to San Luis Obispo. The Summer of 2007 was the opening concert of the Forbes Pipe Organ, which was built elevated into a side wall of Harmon Hall and required the donation of a further $3 million for purchase and installation.
