Orinda, California

Orinda is a city in Contra Costa County, California, United States. The city's population as of the 2020 census is estimated at 19,514 residents.

History
Orinda is located within four Mexican land grants: Rancho Laguna de los Palos Colorados, Rancho Acalanes, Rancho El Sobrante and Rancho Boca de la Cañada del Pinole. The area was originally rural, mainly known for ranching and summer cabins. The Moraga Adobe was built in 1841, and is the oldest building in the East Bay. In the late 19th century, the land was named by Alice Marsh Cameron, probably in honor of the poet Katherine Philips, who was also known as the "Matchless Orinda".

In the 1880s, United States Surveyor General for California Theodore Wagner built an estate he named Orinda Park. The Orinda Park post office opened in 1888. The post office's name was changed to Orinda in 1895. Orinda was also the site of Bryant Station, a stop on the failed California and Nevada Railroad around the turn of the 20th century. Later, the area around Bryant Station was known as Orinda Crossroads.

Orinda's popularity as a year-round residence grew after the 1937 completion of the Caldecott Tunnel, which provided easier access to the west. Bisected by California State Route 24 and framed by its rolling oak-covered hills, the city of Orinda was incorporated on July 1, 1985. Its first mayor was Richard G. Heggie. The city is served by Orinda station on the Bay Area Rapid Transit (BART) and Route 6 of the County Connection.

Geography
According to the United States Census Bureau, the city has a total area of 12.7 sqmi, of which 12.7 sqmi of it is land and 0.015 sqmi of it (0.12%) is water.

Climate
The area is characterized by a warm-summer Mediterranean climate (Köppen climate classification: Csb) with cool, rainy winters and warm, dry summers. Because Orinda is located in a hilly area, microclimates often dominate temperature differences in short distances. The Oakland Hills often block the cool foggy conditions that can be seen in Oakland and the inner Bay. In the summer, fog can spill over the Oakland hills, cooling off the area. Heatwaves from the inland areas can be felt much more in Orinda than in Oakland and the inner Bay during the summer. In the winter, Orinda often sees more precipitation than surrounding areas because of its higher elevation. Snowfall is rare but not unheard of. A dusting of snow may occur in any given year because of the elevation. During stable conditions in the winter, mornings can be cold and frosty in downtown and lower-lying areas, while the higher hills surrounding the area may be several degrees warmer.

Pacheco, California

Pacheco is a census-designated place (CDP) in Contra Costa County, California. The population was 3,685 at the 2010 census. It is bounded by Martinez to the north and west, Concord to the east, and Pleasant Hill to the south.

History
The town was laid out in 1857 by Dr. J. H. Carothers and named for Salvio Pacheco, grantee of the Rancho Monte del Diablo Mexican land grant. A post office operated at Pacheco from 1859 to 1913 and from 1955 to the present.

Pacheco was briefly a prosperous commercial center. During this period, Pacheco Slough was deep enough to receive ocean-based shipping. From 1851 to nearly 1873, Pacheco was the county’s commercial center: the shipping port for the grain grown in the Ygnacio, San Ramon and Tassajara valleys, with warehouses, a flour mill and shops along the creek. Walnut Creek, (then known as Pacheco Creek), then flowed deep and free into Suisun Bay. For over 20 years, Pacheco was a major shipping port for central Contra Costa County.

The destruction of Pacheco’s Walnut Creek shipping channel occurred gradually over many years and for many reasons. Man-made ecologic damage eventually combined with a series of fires and floods, as well as an earthquake, destroyed the town and filled the Slough with silt during the 1860s, to ruin Pacheco's growing prosperity just as similar ones had done to the great classic ports of Ephesus and Troy. Pacheco was subsequently depopulated by the attraction of the nearby town of Todos Santos, later to be known as Concord.

Annexation
In January 2011 the Martinez City Council voted to annex those portions of Pacheco north of California State Route 4. In September 2011, Martinez reached a tax sharing deal to pave the way forward for the annexation. In March 2012, sufficient protests were registered to force an election on the issue. In August 2012, the Martinez Police were mobilized to convince the voters to agree to the proposal.

As part of the annexation, Martinez would take over the management of the new Pacheco transit hub.

In August 2012 North Pacheco rejected annexation. Residents and property owners voted 40-39 against becoming part of Martinez. The 111-acre area remains unincorporated, governed by the County Board of Supervisors.

Opponents of the annexation called it a "bad deal for all" on a website created to oppose the proposal. The site claimed that annexing Pacheco would be too costly for Martinez – a city already suffering a deficit, and that property taxes would go up for residents and businesses. The Contra Costa Times reported that annexation of an area along Interstate 680 from Highway 4 north to the Burlington-Northern Santa Fe railroad crossing was approved by the Contra Costa County Local Area Formation Commission earlier that year. LAFCO's Executive Officer Lou Ann Texeira said that commissioners would have to take action to terminate the annexation at the September 12 meeting. City leaders say that the North Pacheco gateway area offers the potential for profit-making development. The Martinez city council scheduled another vote on the issue, possibly with a larger area.

Pinole, California

Pinole (Spanish for "cornmeal") is a city in Contra Costa County, California, United States. The population was 19,022 at the 2020 census.

History
The Huchiun tribe lived in the region.

In 1823, Ygnacio Martínez, commandant of the Presidio of San Francisco, received a land grant of Rancho El Pinole from the Mexican government. Martinez built a hacienda in Pinole Valley; this is land encompassed by Pinole Valley Park. During the 1850s, Bernardo Fernandez, a Portuguese immigrant, started a trading facility on the shores of San Pablo Bay. He built Fernandez Mansion, a historic building that still stands today at the end of Tennent Avenue. From these early beginnings, a small but thriving community developed into the city of Pinole.

The settlement's growth was stimulated by construction of the Southern Pacific Railroad in 1878 and the establishment of the California Powder Works in nearby Hercules. During this period, this city had an active waterfront and was a regional commercial and banking center. The first post office opened in 1878 when the railroad reached the community. The City of Pinole was incorporated in 1903.

During the post-World War II boom, Pinole and the surrounding area grew rapidly. Construction of Interstate 80 in 1958 stimulated developers to build new housing to satisfy demand, and the town evolved as a suburban bedroom community within the San Francisco/Oakland commuter belt. Much of its original industry was displaced during this time, and the town became predominantly residential.

Today, the town is locally known for its "big box" shopping store district along Fitzgerald Drive, and Pinole Vista Shopping Center, which is contiguous with Richmond's Hilltop Area. The downtown area still retains much turn-of-the-century building stock. The city's development agency is working to preserve this historic area as a tourist and community destination.

Geography

According to the United States Census Bureau, the city has a total area of 13.6 sqmi. 5.3 sqmi of it is land, and 8.3 sqmi of it (60.79%) is water.

The city of Pinole has habitat areas that support the endangered species Santa Cruz Tarweed on the California coastal prairie ecosystem. A colony of this rare plant was discovered during preparation of an Environmental Impact Report for a proposed shopping center on the east side of I-80 in the late 1980s. Subsequently, a plan was developed by the city to conduct replanting of this tarweed on the slopes within the right-of-way of Interstate Highway 80. Also running through is Pinole Creek.

2010

At the 2010 census Pinole had a population of 18,390. The population density was 1,354.7 PD/sqmi.

Pittsburg, California

Pittsburg is a city in Contra Costa County, California, United States. It is an industrial suburb located on the southern shore of the Suisun Bay in the East Bay region of the San Francisco Bay Area, and is part of the Sacramento–San Joaquin River Delta area, the Eastern Contra Costa County area, and the San Francisco Bay Area. The population was 76,416 at the 2020 United States Census.

History

Originally settled in 1839 as “Rancho Los Medanos”, the area of almost 10,000 acres was issued to Californios Jose Antonio Mesa and his brother Jose Miguel under a Mexican Land Grant by then Governor Juan Bautista Alvarado, one of the final land grants issued prior to the formation of California as a state.

In 1849, during the California Gold Rush, Colonel Jonathan D. Stevenson (from New York) bought the Rancho Los Medanos land grant for speculation, and laid out a town he called "New York of the Pacific". General William Tecumseh Sherman laid out the first network of streets on the west side of town. The area was the midway stopping point for schooners traveling from San Francisco to the gold country further inland. Fishing, farming, and cattle raising for the hide and tallow industry were the major economic activities during this time.

In 1859, with the discovery of coal in the nearby town of Nortonville, the place became a port for coal. The Black Diamond Coal Mining Company commenced operations, building the Black Diamond Coal Mining Railroad to Nortonville. Steam powered engines moved coal cars down the tracks along present day Railroad Avenue to the waterfront docks that came to be called "Black Diamond Landing." The boom ended in 1885, and the company moved to Washington state to work a new claim.

In the 1870s, commercial fishing took hold and the Black Diamond Cannery was established at the foot of Los Medanos St. By 1882, a network of ten canneries was formed along the Sacramento Delta. An industry was born with fishermen, packing plants, boat builders and the like dominating the local waterfront for the next 80 years. The town boasted the largest Delta fishing community in the state, made up primarily of Sicilian immigrants, the families of which have remained in the area for generations. In 1957, the State of California closed down the Sacramento Delta to commercial fishing, ending the area's industry.

In 1900, C.A. Hooper purchased the land grant and gave birth to many manufacturing ventures, beginning in 1903 with the creation of the Industrial Center of the West. Hooper secured additional capitalization and provided property for the Columbia Steel Company, which, in 1910, opened its California steel plant in Pittsburg with one foundry and a crew of 60 employees. It made steel castings for the dredging, lumber and shipping industries.

In 1903 the town was incorporated, and by a vote of the citizenry, was renamed "Black Diamond", after the mining firm. Because of the industrial potential of the site, a name change to Pittsburg was proposed in 1909. On February 11, 1911, the city officials changed the town's name to "Pittsburg", honoring Pittsburgh, Pennsylvania, as the two cities shared a common steel and mining industrial heritage. This rechristening came at a time when the name of Pittsburgh, Pennsylvania was more commonly spelled without the "h". In 1918 the shipyard of the Pacific Coast Shipbuilding Company was built in neighboring Bay Point, the associated company town of Clyde, California alongside it, but as soon as the World War I shipbuilding boom was over, the yard was closed in 1921.

In 1930, Columbia Steel became a subsidiary of U.S. Steel. At that point the company had expanded into Utah and was worth $40,000,000. The Pittsburg plant continued to grow until the early 1950s, reaching a peak staff of 5,200 employees when the markets for its products crashed. The parent company (by 1986, renamed as USS Company) had merged with Korean Pohang Iron and Steel Company. Together they invested $450 million turning the Pittsburg plant into a modern flat-products mill, renamed as USS-Posco. As of 1999, the facility employed 970 workers and shipped over 1.6 million U.S. tons per year of steel to over 175 customers in the Western U. S., Mexico, Canada and the Pacific Rim.

The original town site fronts on the Sacramento/San Joaquin River Delta, reflecting its origins as a deep water channel river port (As of January 1, 2007, state legislation [Assembly Bill 2324] enabled the city to manage its own riverfront for commercial development and subsequent port operations). Since the early 1900s, the city has grown inland to the south, then spread east and west along State Route 4, now a freeway carrying resident commuters to jobs in the San Francisco Bay-Oakland Region. In the process, the former town of Cornwall, California was absorbed. As of the 2000 census, the city had a total population of 56,769.

Camp Stoneman was built in 1942, and was a major staging area for the United States Army during World War II and the Korean War until 1954.

The first post office opened in 1868 as Black Diamond, and changed its name with the town's in 1911.

Pleasant Hill, California

Pleasant Hill is a city in Contra Costa County, California, United States, in the East Bay of the San Francisco Bay Area. The population was 34,613 at the 2020 census. It was incorporated in 1961. Pleasant Hill is the home of College Park High School, Diablo Valley College, the Pleasant Hill Library of the Contra Costa County Library system, and the Pleasant Hill Recreation & Park District.

History and architecture
Before colonization the area was inhabited by members of the Bay Miwok people. The San Ramon Valley Branch Line of the Southern Pacific entered service in 1891 with two flag stops in the area that would become the City of Pleasant Hill: Hookston, located today where the Iron Horse Regional Trail crosses Hookston Road, and Sparkle, where the Southern Pacific and Sacramento Northern Railway intersected and today stands the Pleasant Hill BART station. The area began to be suburbanized in the 1920s following prohibition, as the many local vineyards were removed and the formerly agricultural land was subdivided for housing. Monument Boulevard was named after the Soldiers Memorial Monument to commemorate veterans and war dead of World War I from Contra Costa County. It was erected on December 11, 1927, at the intersection of Monument Boulevard and the Contra Costa Highway, now Contra Costa Boulevard. The monument depicts one black and three white soldiers. It is 45 ft tall, constructed of formed concrete, and weighs 150 tons. In 1954 the monument was moved to its current site at the intersection of Boyd Road and Contra Costa Boulevard to make way for the construction of State Route 21.

Developed largely in the years following World War II, the area did not have a post office until 1948. The city incorporated in 1961.

On February 21, 1967, Century 21 Theaters opened an 895-seat dome theater between Monument Boulevard and Hookston Road, just off I-680. The futuristic dome-topped cinema became an iconic landmark for the newly incorporated city. The theater was designed by prolific Bay Area architect Vincent G. Raney. It had a distinctive 50-foot-high domed ceiling and oversized curved screen. The theater was initially built to showcase the Cinerama widescreen process developed in the 1950s. The screen was later updated to standard flat-screen. In 1973, four additional single-screen auditoriums were added to the front of the building. Renamed as Century 5 Theatres, it continued to be known familiarly as the Dome.

The city hall of Pleasant Hill was designed by architect Charles Moore. Completed in the late 20th century, it has won several awards for architectural design.

For most of its history, Pleasant Hill did not have a true downtown or Main Street. In 1991, the city began planning the redevelopment of the area around the intersection of Monument and Contra Costa boulevards. In July 2000, Downtown Pleasant Hill finally opened. The privately owned and operated outdoor shopping center was designed to resemble a typical small Main Street.

Starting in 2003, CinéArts operated the former Century 5 Theatres, screening primarily independent and foreign films. Due to changes in viewing habits, as many people screened movies at home, business continued to decline. The theater's property owner, SyWest Development, closed the Dome on April 21, 2013. On its last night of operation, CinéArts screened Stanley Kubrick's classic 2001: A Space Odyssey.

Sywest gained the approval of the Pleasant Hill City Council for its proposal to tear down the theater and redevelop the property as a two-story, 73,000+ square-foot building to house a Dick's Sporting Goods. Supporters of the theater submitted two separate appeals to overturn the approval of demolition: one by a resident of Pleasant Hill, and one by Save the Pleasant Hill Dome (SPHD) organization. Both appeals were voted down by a majority of the city council; Mayor Michael G. Harris and councilmember Ken Carlson voted in favor of the appeal. SyWest had the Dome demolished on May 8, 2013, precluding any further court action.

On October 14, 2019, a magnitude 4.5 earthquake shook the city.

Geography and climate
According to the United States Census Bureau, the city has a total area of 7.1 sqmi. Pleasant Hill has a varied landscape with some valleys and rolling hills. In undisturbed wilderness, oak woodlands and mixed woods can be found. It is located in the central East San Francisco Bay.

This region has warm and dry summers, with no average monthly temperatures above 71 F. According to the Köppen Climate Classification system, Pleasant Hill has a warm-summer Mediterranean climate, abbreviated "Csb" on climate maps. Winter daytime temperatures tend to be in the fifties to low sixties, and summers range in the seventies to upper eighties, occasionally reaching the low nineties. On very rare occasions, the temperatures can reach the one hundred degree range during extreme heat waves. Freezing in winter is rare, but it does happen. Summer fog is occasional but winter fog is very common.

Planning and environmental factors
The Gregory Gardens subdivision developed in 1950 required purchasers of new homes to accept a Covenant that restricted ownership to Caucasians (such provisions have since been ruled as unconstitutional). The Covenant also limited the structures that could be built, animals allowed on premises, and commercial activities.

Pleasant Hill used a system of environmental planning at a relatively early stage of its modern growth. Notably the city authorized a study in the 1980s of hillside development, which included detailed mapping of biota, geotechnical hazards, sound levels and other environmental constraints. These studies were used to establish appropriate zoning and development densities for all the principal undeveloped hillside areas within the city.

Port Costa, California

Port Costa is a small town and census-designated place (CDP) in Contra Costa County, California, located in the East Bay region of the San Francisco Bay Area. Situated on the southern shore of the Carquinez Strait, the population was 190 in 2020 according to the United States Census Bureau.

History
Port Costa was founded in 1879 as a landing for the railroad ferry Solano, owned and operated by the Central Pacific Railroad. This put Port Costa on the main route of the transcontinental railroad. The Solano, later joined by the Contra Costa, carried entire trains across the Carquinez Strait from Benicia to Port Costa, from where they continued on to the Oakland Pier.

Businessman George W. McNear built the Port Costa Warehouses and Dock Company west of the new ferry terminal in 1880. The valley where Port Costa now sits, at one point called Bull Valley, was part of a ranch owned by William Piper. In 1883, McNear bought Piper's land for $100,000 and began to build up the town. Port Costa became the busiest port on the West Coast, primarily shipping wheat.

Port Costa's first post office was established in 1881 with postmaster Kate Hurley. It later moved to a warehouse built by McNear, where it remains today. The Port Costa School, a classical revival building designed by architect William Wilde, was built in 1911, opened in 1912, and operated until 1966. In 1988, it was added to the National Register of Historic Places. St. Patrick Church was founded in 1884, rebuilt in 1898, and restored in 1980.

For the early decades of Port Costa's existence, much of the town's commercial activities took place on wharves and docks along the waterfront. These wharves and docks suffered from numerous fires between 1883-1941, and a large part of the "Waterfront Port Costa" area was demolished in 1921 after being badly damaged by shipworms. No docks or wharves are left standing today, although pilings remain.

Besides the railroad and shipping, another important industry in Port Costa was brick making. Port Costa Brick Works operated from 1905 until 1991.

After California's wheat output dropped in the early 20th century and especially after the Southern Pacific (which took over the operations of the Central Pacific) constructed a railroad bridge at Martinez in 1930 to replace the ferry crossing, Port Costa lost population and importance.

In 1963, Bill Rich purchased and renovated multiple Port Costa buildings, including the Burlington Hotel (built circa 1883) and McNear's warehouse (built 1886), with the goal of making the town a tourist attraction. Under this iteration, the warehouse housed multiple antique stores and, for two years, artist Clayton Bailey's Wonders of the World Museum. However, Port Costa fell into decline after a 1983 fire in the hills between Port Costa and Crockett.

In 1999, known biker bar the Warehouse Cafe, located in the warehouse originally built by McNear, was purchased by a new owner and gained a "cult following" over the decades. In 2012, the restaurant Bull Valley Roadhouse, which sits in McNear's old office building, was renovated. In the following year, the Burlington Hotel was renovated by new owners as well. Port Costa continues to be a destination for day or weekend trips.

Geography
According to the United States Census Bureau, the CDP has a total area of 0.16 sqmi, all of it land. Port Costa is surrounded by rolling hills grazed by cattle and managed by East Bay Regional Park District. Carquinez Strait Regional Shoreline stretches from Crockett through Port Costa and to Martinez. Big Bull Valley Creek runs along McEwen Road into a historic reservoir just above the town, then it runs in an underground pipe culvert beneath the town to the Carquinez Strait.

Demographics
The 2010 United States Census reported that Port Costa had a population of 190. The population density was 1,200.1 PD/sqmi. The racial makeup of Port Costa was 172 (90.5%) White, 2 (1.1%) African American, 2 (1.1%) Native American, 7 (3.7%) Asian, and 7 (3.7%) from two or more races. Hispanic or Latino of any race were 10 persons (5.3%).

There were 99 households, out of which 15 (15.2%) had children under the age of 18 living in them, 37 (37.4%) were opposite-sex married couples living together, 4 (4.0%) had a female householder with no husband present, 5 (5.1%) had a male householder with no wife present. There were 10 (10.1%) unmarried opposite-sex partnerships, and 3 (3.0%) same-sex married couples or partnerships. 42 households (42.4%) were made up of individuals, and 9 (9.1%) had someone living alone who was 65 years of age or older. The average household size was 1.92. There were 46 families (46.5% of all households); the average family size was 2.61.

The population was spread out, with 19 people (10.0%) under the age of 18, 13 people (6.8%) aged 18 to 24, 38 people (20.0%) aged 25 to 44, 80 people (42.1%) aged 45 to 64, and 40 people (21.1%) who were 65 years of age or older.

Rodeo, California

Rodeo (Spanish for "Cattle roundup") is a census-designated place (CDP) located in Contra Costa County, California, in the East Bay sub-region of the San Francisco Bay Area, on the eastern shore of San Pablo Bay, 25 miles northeast of San Francisco. The population was 9,653 at the 2020 census. The town is named for the rodeos common in the late 19th century. Cattle from the surrounding hills were regularly driven down through the old town to a loading dock on the shoreline of San Pablo Bay for shipment to slaughterhouses, a practice which continued through the early 20th century. The town of Rodeo is served by the Interstate 80 freeway and State Route 4. The Southern Pacific Railroad main line passes through Rodeo. Rodeo has not been a stop on the railroad since the 1950s.

History
Rodeo owes much of its history to brothers John and Patrick Tormey, who purchased tracts of land from the Ygnacio Martinez Rancho El Pinole estate in 1865 and 1867.

They became successful ranchers and businessmen, amassed sizable fortunes and held public office. Patrick Tormey (for whom the nearby town of Tormey is named) had visions of this area of Contra Costa County becoming the meatpacking and canning center of the Pacific coast. In partnership with the Union Stockyard Co. in 1890, he sold some of the land to them and began to lay out plans and make large investments for the stockyard facilities. Eventually, streets were graded and lots were prepared for homesteads, thus creating the town of Rodeo.

Patrick Tormey also sold land in the nearby town of Oleum to the California Lumber Co. for use as a lumberyard (which eventually would be sold to the Union Oil Co. for an oil refinery site). He also sold land in nearby Selby, which was used by the Selby Smelting & Lead Co. He funded the meatpacking plant, corrals and the Rodeo Hotel.

The first post office opened in 1892.

After recession in 1893, Patrick Tormey struggled to keep finances going as business began to close, culminating with the bankruptcy of the Union Stockyard Co. Patrick Tormey was plagued with lawsuits over the bankruptcy for the remainder of his life. Residents were able to find work in nearby towns of Crockett (C&H Sugar), Vallejo (the Mare Island Naval Shipyard), Hercules (Hercules Powder Co.), and Union Oil Co. in Oleum.

Rodeo as a community managed to continue, but was devastated in the 1906 San Francisco earthquake.

San Pablo, California

San Pablo (Spanish for "Saint Paul") is an enclave city in Contra Costa County, California, United States. The population was 32,127 at the 2020 census. The current Mayor is Patricia Ponce. Currently, the City Council consists of Abel Pineda, Arturo Cruz, Elizabeth Pabon-Alvarado, and Rita Xavier. Ponce is Mayor, and Cruz, Pabon-Alvarado, and Xavier are Council Members. Dorothy Gantt is the city Clerk. Viviana Toledo is the city Treasurer.

History

The city of San Pablo is situated on land once occupied by the Cuchiyun band of the Ohlone indigenous people. This Ohlone territory was claimed for the king of Spain in the late 18th century. and was granted for grazing purposes to the Mission Dolores located in today's San Francisco, but these church properties were secularized (or made separate from the Catholic church) when Mexico became independent from Spain in 1821.

In 1823, Mexican Governor Luís Antonio Argüello granted the Ohlone territory to Francisco María Castro, an ex-soldier stationed at the San Francisco Presidio, Francisco María Castro. The grant was given the name Rancho San Pablo. This is the origin of the city's name, as well as the name of one the East Bay's oldest principal roads: San Pablo Avenue (formerly known, during the Spanish colonial era, as El Camino Real de la Contra Costa, which means "The Royal Way of the Opposite Coast," referring to the costal region opposite San Francisco). San Pablo Avenue, originating in San Pablo, runs through the entire East Bay. San Pablo's Alvarado Adobe has been designated a California State Landmark (No.512), as a historic reproduction of the city's Mexican era. The home was originally constructed in 1842 by Jesús Maria Castro, one of Francisco Castro's sons, for his mother, Gabriéla Berryessa de Castro. Upon Gabriéla's death in 1851, it was inherited by her daughter, Martina Castro de Alvarado, wife of Juan Bautista Alvarado, who was Governor of California from 1836 to 1842. The Alvarado Adobe was demolished in the mid-20th century to make way for a motel. A reproduction was built later in the century, and is now located in San Pablo Civic Center, on the northwest corner of San Pablo Avenue and Church Lane. A single beam from the original structure is incorporated into the roof of the replacement structure, at the rear of the adobe facing the interior courtyard.

The first post office was established in 1854. The city incorporated in 1948.

Since the middle of the 20th century, College Center at El Portal has been the backbone of the community's retail economy.

Geography
According to the United States Census Bureau, the city has a total area of 2.6 sqmi, all land.

San Pablo lies on a sedimentary plain between the northern end of the Berkeley Hills and San Pablo Bay, although the city limits do not extend to the bayshore. Two principle creeks traverse the city: Wildcat Creek and San Pablo Creek. Both originate in the mountain ranges to its southeast. The minor Rheem Creek also runs through the city.

The northeastern limits of San Pablo are also traversed by the Hayward Fault, a major branch of the San Andreas Fault, which lies to the west.

Interstate 80 (Eastshore Freeway) passes through San Pablo.

There are several communities to the north of (and separated from) the city, but which have San Pablo mailing addresses. These include the census areas of Tara Hills, Bayview, and Montalvin.

San Ramon, California

San Ramon (Spanish: San Ramón, meaning "Saint Raymond") is a city in Contra Costa County, California, United States, located within the San Ramon Valley, and 34 mi east of San Francisco. San Ramon's population was 84,605 per the 2020 census, making it the 4th largest city in Contra Costa County, behind Richmond, Concord and Antioch.

San Ramon is home to the headquarters of Chevron Corporation, Cooper Companies, the West Coast headquarters of AT&T, GE Digital, as well as the San Ramon Medical Center. Major annual events include the Art and Wind Festival on Memorial Day weekend and the Run for Education in October.

On April 24, 2001, San Ramon was designated a Tree City USA.

History

The lands now occupied by the City of San Ramon were formerly inhabited by Seunen people, an Ohlone/Costanoan group who built their homes near creeks. Sometime around 1797, they were taken by Mission San José for use as grazing land. In 1834, they were part of the Rancho San Ramon land grant to José María Amador.

Amador named not after a real saint but rather after a Native American vaquero who tended mission sheep on the land. Amador added the "San" per Spanish custom. In 1850, the first permanent American settlers, Leo and Mary Jane Norris, purchased the northwest corner of Amador's Rancho San Ramon, near the intersection of present-day Bollinger Canyon Road and Crow Canyon Road.

The tracks for the San Ramon Branch Line of the Southern Pacific Railroad were laid down and completed in 1891. The line extended from San Ramon to an unincorporated area known as Avon, east of Martinez, where it connected to the Oakland/Stockton Line. On February 7, 1909, Southern Pacific extended the line south to Radum (near Pleasanton). In 1934, passenger service ended. By 1986, Contra Costa County had obtained the railroad right-of-way and the Iron Horse Regional Trail was established along its path.

Geography

Mount Diablo flanks the city to the northeast and is prominently visible from almost all parts of the city. The Las Trampas Regional Wilderness borders San Ramon's extreme northwest, at the northern end of Bollinger Canyon. The smaller Bishop Ranch Regional Preserve straddles San Ramon's western border, located approximately between Interstate 680 and the Alameda County line.

The topography of San Ramon is varied, featuring a mix of the rolling hills of the Diablo Range and the flatter basin of the San Ramon Valley. The city is predominantly urban and residential with many new housing developments; however, much of the land around the city's perimeter regions remains undeveloped, and is covered by grasslands and oak tree orchards. During the drier months the grasses are golden, but with the precipitation of winter and spring, the grasses turn green.

Climate
San Ramon's weather typifies a Mediterranean climate, seasonal, and moderate. Summers can range from warm to hot and dry, while winters are mild or cool, wet and rather short. Its weather is similar to the adjacent cities of Danville, Dublin and Pleasanton. Fog can be infrequent but occurs normally in the western reaches of the city, at the eastern mouth of Crow Canyon, through which marine weather patterns funnel in from the San Francisco Bay via Castro Valley. It usually burns off by mid-to-late morning.

Economy

Bishop Ranch, a master-planned office park development, with some retail elements, began major construction in the early 1980s, and provides a healthy tax base for the city. Bishop Ranch is situated on 585 acres once owned by Western Electric, and was farmland before that. Current tenants include the corporate headquarters of Chevron Corporation (formerly ChevronTexaco), as well the West Coast headquarters of AT&T Inc. (which had been the headquarters of Pacific Bell from about 1983, when it relocated from downtown San Francisco, until the merger with SBC Communications that created the current AT&T). United Parcel Service has a regional distribution center in Bishop Ranch. Toyota has a regional office and parts distribution center located there. GE Global Research started its Global Software Center in Bishop Ranch in 2011. Bishop Ranch covers the vast majority of "Central San Ramon", which is the large square formed by Freeway 680 on the west, Crow Canyon Road on the north, Iron Horse trail on the east, and Bollinger Canyon Road on the south (though several complexes are south of Bollinger). In December 2016, the Ligier EZ-10 began use in the first autonomous vehicle passenger shuttle route in North America, looping through Bishop Ranch Office Park, with on-sight operation and maintenance by First Transit.

ChevronTexaco's headquarters moved from San Francisco to San Ramon in 2001 but 12 years later, 800 jobs were moved to Houston, a quarter of the San Ramon workforce due to high corporate costs and to consolidate existing units in Houston.

According to USA Today in 2020, San Ramon was not only the wealthiest city in California, but also in the entire United States.

Memorial Park

Originally, this city park, located on a hill overlooking Bollinger Canyon Road and San Ramon Valley Blvd., was to be named Alta Mesa Park. During the construction of the park, the City Council voted to change the name to Memorial Park to honor Tom Burnett, a San Ramon resident, and other victims from Flight 93 killed in the September 11 attacks of 2001. A plaque was installed at the base of a lighted flagpole dedicated to those victims and the surrounding meadow is part of the city's memorial tree program dedicated to local residents who have perished. The park was dedicated on September 11, 2002.

This 16-acre park includes a play area, a BMX course, a picnic area, a bocce ball court, horseshoe courts, a ball field, a dog park, restrooms and water fountains (including a doggy water fountain). The play area has two big play structures, one for ages 2–5 and another for ages 5–12.
