Since its incorporation in 1902, the city's population has grown as it annexed nearby unincorporated areas. The city's July 2019 population (not including East Porterville) was estimated at 59,599.
During California's Spanish period, the San Joaquin Valley was considered a remote region of little value. Emigrants skirted the eastern foothills in the vicinity of Porterville as early as 1826. Swamps stretched out into the Valley floor lush with tall rushes or "tulare" as the Indians called them.
Gold discovered in 1848 brought a tremendous migration to California, and prairie schooners rolled through Porterville between 1849 and 1852. Starting in 1854, Peter Goodhue operated a stopping place on the Stockton - Los Angeles Road on the bank of the Tule River. Wagon trains of gold seekers passed through the village, but other travelers found the land rich and remained to establish farms. A store was set up in 1856 to sell goods to miners and the Indians, who lived in tribal lands along the rivers. From 1858 to 1861 it was the location of the Tule River Station of the Butterfield Overland Mail.
Royal Porter Putnam came to the village in 1860 to raise cattle, horses and hogs. He bought out Goodhue the same year and turned the station into a popular stopping place and hotel called Porter Station. He bought 40 acres of land and built a two-story store and a hotel on the highest point of the swampy property, which is now the corner of Oak and Main. The town of Porterville was founded there in 1864. It took its name from the founder's given name because another Putnam family lived south of town.
In 1862 20.8 inches (530 mm) of rain fell in the area, causing a change of course of the Tule River. Putnam's acres drained and he had his property surveyed, staking out lot lines and establishing streets. Settlers were offered a free lot for every one purchased. The need of a burgeoning California population for food provided the impetus that led to the permanent development of the east side of the southern San Joaquin Valley. The long, dry, hot summer prompted irrigation of the lands.
In 1888 the Southern Pacific Railway brought in the branch line from Fresno. The Pioneer Hotel and Bank were built by businessmen from San Francisco. Porterville incorporated in 1902, as miners moved into the area to extract magnesite ore, and the Chamber of Commerce was formed in 1907. A City Manager-Council form of government was adopted in 1926 and a Charter was adopted. The city has grown from a community of 5,000 in 1920. Agriculture supplemented by the Central Valley Water Project has been the major source of economic growth in the area. The city is the center of a large farming area especially noted for citrus and livestock.
Industry has become a significant factor in the development of the community. The Wal-Mart Distribution Center, National Vitamin, Beckman Instruments, Standard Register, Sierra Pacific Apparel, Royalty Carpeting and other small companies have facilities in Porterville. Several large public facilities are also located here. These include the Porterville Developmental Center, Sequoia National Forest Headquarters, the Army Corps of Engineers Lake Success Facility and the Porterville College campus of the Kern Community College District.
The Tule River Indian War of 1856
The Native Americans living in the foothills of the Sierra Nevada Mountains were relatively undisturbed by early Spanish colonization. During the late 1840s and into the 1850s, once gold was discovered in California, miners began encroaching on traditional lands. Although a treaty was signed with the local tribes in 1851, defining a proposed reservation and 200 head of cattle per year, the US Senate failed to ratify it, with every member either abstaining or voting no.
In the spring of 1856, a rumor that 500 cattle had been stolen by Native Americans began to circulate. Upon further investigation, it turned out that a single yearling calf had been taken as a bridal gift. Mobs of armed settlers were organized to counter the perceived menace, despite the peaceful intentions of the Native Americans. These mobs began raiding Native camps and killing their inhabitants.
One mob, under the leadership of Capt. Foster DeMasters, failed to dislodge a numerically superior Native encampment while wearing ineffective makeshift body armor consisting of cotton-padded jackets. Reinforcements were sent in from Keyesville and the resulting force, now under the leadership of Sheriff W.G. Poindexter, were similarly repulsed. After falling back, the mob then proceeded to wage a scorched-earth campaign by destroying Native American supply caches.
News of these engagements spread throughout California, exaggerating the degree of menace and misrepresenting its causes. Finally, in May 1856 army troops under the command of LaRhett Livingston assaulted the encampment and succeeded in driving off its defenders. The war's duration was approximately six weeks.
In retrospect, George Stewart wrote, "Thus ended the Tule River war of 1856; a war that might have been prevented had there been an honest desire on the part of the white settlers to do so, and one that brought little glory to those who participated therein. The responsibility cannot now be fixed where it properly belongs. Possibly the Indians were to blame. Certainly, the whites were not blameless, and it is too seldom, indeed, that they have been in the many struggles with the aboriginal inhabitants of this continent."
Historian Annie Mitchell later wrote in the Tulare County Historical Society bulletin (Los Tulares No. 68, March 1966): "Over the years it has been assumed that the Tule River War was a spontaneous, comic opera affair. It was not and if the Indians had been armed with guns instead of bows and a few pistols they would have run the white men out of the valley."
Porterville is located at (36.068550, -119.027536).
According to the United States Census Bureau, the city has a total area of 17.7 square miles (46 km2), of which, 17.6 square miles (46 km2) of it is land and 0.1 square miles (0.26 km2) of it (0.41%) is water.
Porterville is located on the Tule River at the base of the western foothills of the Sierra Nevada and easternmost section of California's Central Valley. In the foothills above Porterville is the man-made Lake Success.
Porterville, lying along the foothills of the Sierras at an elevation of 455 feet (139 m), is located on State Highway 65, 165 miles (266 km) north of Los Angeles, and 171 miles (275 km) east of the Pacific Coast. The city has a strategic central location to major markets and a ready access to major transportation routes.
Porterville is subject to earthquakes due to its location within the Pacific Ring of Fire. The geologic instability involves numerous faults, which cause many earthquakes every year, but most are of low intensity and are not felt. The primary plate boundary is the San Andreas Fault, which was the source of the 1857 Fort Tejon earthquake. Another major event that affected the Porterville area was the Kern County sequence of shocks that occurred on the White Wolf Fault during July and August 1952. Most parts of the city are also vulnerable to floods. The San Joaquin Valley and metropolitan areas are also at risk from blind thrust earthquakes.
Porterville has a cool semi-arid climate (Köppen BSk) that is close to both a mediterranean climate (Csa) and a hot semi-arid climate (BSh). It is characterized by sweltering and arid summers, and pleasant winters with frosty mornings and occasional heavy rainfall.

Owing to geography, heavy reliance on automobiles and agriculture, Porterville suffers from air pollution in the form of smog. The Porterville area and the rest of the San Joaquin Valley are susceptible to atmospheric inversion, which holds in the exhausts from road vehicles, airplanes, locomotives, agriculture, manufacturing and other sources. Unlike other cities that rely on rain to clear smog, Porterville gets only 13.00 inches (330.20 mm) of rain each year: pollution accumulates over many consecutive days. Issues of air quality in Porterville and other major cities led to the passage of early national environmental legislation, including the Clean Air Act. More recently, the state of California has led the nation in working to limit pollution by mandating low-emission vehicles. Smog levels are only high during summers because it is dry and warm. In the winter, storms help to clear the smog and it is not as much of a problem. Smog should continue to drop in the coming years due to aggressive steps to reduce it, electric and hybrid cars and other pollution-reducing measures taken.
As a result, pollution levels have dropped in recent decades. The number of Stage 1 smog alerts has declined from over 100 per year in the 1970s to almost zero in the new millennium. Despite improvement, the 2006 annual report of the American Lung Association ranked the city as the 11th most polluted in the country, with short-term particle pollution and year-round particle pollution. In 2007 the annual report of the American Lung Association ranked the city as the 4th most polluted in the country with short-term particle pollution and year-round particle pollution. In 2008, the city was ranked the third most polluted and again fourth for highest year-round particulate pollution.
Porterville is also experiencing environmental issues due to California's extreme drought. Most of the nearby unincorporated area of East Porterville has run out of its supply of groundwater, an unfortunate consequence of the entire unincorporated area relying heavily on private wells. Porterville spent much of 2014 sending shipments of bottled water to East Porterville.

Under the California State Constitution, there is a difference in powers granted to cities. A "General Law City" is one, which operates exclusively under State law. The City Charter, in accordance with the State Constitution, provides the City with authority for "Home Rule" whereby the City is given the power to make and enforce within its own boundaries any law, which does not conflict with the State or Federal Government. The State Constitution gives this right of "Home Rule" to any city.
Porterville has operated as a Charter City since 1926, but the Charter has been changed by the voters several times since then.
During the November 2008 Prop 8 election campaign, Porterville's City Council was the only City Council in all of California that passed a Resolution in favor of Prop 8. The Resolution urged voters to act on behalf of the Council's personal, religious, and political interests. Local gay rights activists, such as Porterville LGBTQ, protested at subsequent City Council meetings for months afterwards, getting the attention of local media. Prop 8 amended California's constitution to deny marriage rights for same-sex couples. Porterville, and Tulare County voters voted over 75% in favor of Prop 8, among the highest levels in the State of California, during the election. On August 4, 2010, Prop 8 was ruled unconstitutional under the 14th Amendment of the US Constitution. In June 2013, the mayor declared that month to be LGBT pride month, but that proclamation was subsequently rescinded by the city council. The City Council subsequently removed the Mayor responsible for introducing the proclamation, Virginia Gurrola. During a discussion on the establishment of anti-bullying youth safe zones, Gurrola's successor, Cam Hamilton, stated "I’m against bullying, but I’m getting damn tired of it being used as a mantra for everything when all most people have to do is grow a pair and stick up for them damn selves."

The new nine-courtroom, 96,000-square-foot courthouse replaced the previous overcrowded Porterville Courthouse. Completed in fall 2013, the $93 million courthouse — which was built by Sundt Construction Inc. and designed by CO Architects — provides the necessary space for expansion and enhanced security, enabling the court to greatly improve access and services.
The facility features chambers, courtroom holdings, jury deliberations rooms, support services, clerks offices and work areas, public walk-up windows and queuing, holding and below-grade sally port. The approximately eight-acre site includes parking and circulation and a featured courtyard scheme.
The courthouse is designed to achieve a LEED Silver certification by the U.S. Green Building Council. The building includes high-performance glass, window-shading devices to prevent direct sunlight, and better-insulated walls and roof, and a rain screen system.
It has more energy-efficient mechanical units, which incorporate the partial use of chilled beam passive cooling and radiant heat. The lighting will be high-efficient fluorescent and LED fixtures.
Other sustainable features include: low-use water fixtures and landscape, green roofs, recycling construction materials, the use of regional material and renewable materials as well as certified wood and natural light.
The center was funded under the Trial Court Facilities Act of 2002, made the state of California responsible for court facilities and court construction statewide, and designated a portion of court-user fees and penalties collected to fund the project.
