Contra Costa County is a county located in the U.S. state of California. As of the 2010 census, the population was 1,049,025.[3] The county seat is Martinez.[4][5] The name is Spanish for "opposite coast".[6]

Contra Costa County is included in the San Francisco-Oakland-Hayward, CA Metropolitan Statistical Area. It occupies the northern portion of the East Bay region and is primarily suburban.

History

Pre-human

In prehistoric times, particularly the Miocene epoch, portions of the landforms now in the area (then marshy and grassy savanna) were populated by a wide range of now extinct mammals, known in modern times by the fossil remains excavated in the southern part of the county. In the northern part of the county, significant coal and sand deposits were formed in even earlier geologic eras. Other areas of the county have ridges exposing ancient but intact (not fossilized) seashells, embedded in sandstone layers alternating with limestone. Layers of volcanic ash ejected from geologically recent but now extinct volcanoes, compacted and now tilted by compressive forces, may be seen at the site of some road excavations. This county is an agglomeration of several distinct geologic terranes, as is most of the greater San Francisco Bay Area, which is one of the most geologically complex regions in the world. The great local mountain Mount Diablo has been formed and continues to be elevated by compressive forces resulting from the action of plate tectonics and at its upper reaches presents ancient seabed rocks scraped from distant oceanic sedimentation locations and accumulated and lifted by these great forces. Younger deposits at middle altitudes include pillow lavas, the product of undersea volcanic eruptions.

Native American period

There is an extensive but little recorded human history pre-European settlement in this area, with the present county containing portions of regions populated by a number of Native American tribes. The earliest definitively established occupation by modern man (Homo sapiens) appears to have occurred six to ten thousand years ago. However, there may have been human presence far earlier, at least as far as non–settling populations are concerned. The known settled populations were hunter-gatherer societies that had no knowledge of metals and that produced utilitarian crafts for everyday use (especially woven reed baskets) of the highest quality and with graphic embellishments of great aesthetic appeal. Extensive trading from tribe to tribe transferred exotic materials such as obsidian (useful for the making of arrowheads) throughout the region from far distant Californian tribes. Unlike the nomadic Native American of the Great Plains it appears that these tribes did not incorporate warfare into their culture but were instead generally cooperative. Within these cultures the concept of individual or collective land ownership was nonexistent. Early European settlers in the region, however, did not record much about the culture of the natives. Most of what is known culturally comes from preserved contemporaneous and excavated artifacts and from inter-generational knowledge passed down through northerly outlying tribes of the larger region.

Spanish colonial

Early interaction of these Native Americans with Europeans came with the Spanish colonization via the establishment of missions in this area, with the missions in San Jose, Sonoma, and San Francisco and particularly the establishment of a Presidio (a military establishment) in 1776. Although there were no missions established within this county, Spanish influence here was direct and extensive, through the establishment of land grants from the King of Spain to favored settlers.

Mexican land grants

In 1821 Mexico gained independence from Spain. While little changed in ranchero life, the Mexican War of Independence resulted in the secularization of the missions with the re-distribution of their lands, and a new system of land grants under the Mexican Federal Law of 1824. Mission lands extended throughout the Bay Area, including portions of Contra Costa County. Between 1836 and 1846, during the era when California was a province of independent Mexico, the following 15 land grants were made in Contra Costa County.[7]

The smallest unit was one square league, or about seven square miles, or 4,400 acres (17.8 km2), maximum to one individual was eleven leagues, or 48,400 acres (195.9 km2), including no more than 4,428 acres (17.9 km2) of irrigable land. Rough surveying was based on a map, or diseño, measured by streams, shorelines, and/or horseman who marked it with rope and stakes. Lands outside rancho grants were designated el sobrante, as in surplus or excess, and considered common lands. The law required the construction of a house within a year. Fences were not required and were forbidden where they might interfere with roads or trails. Locally a large family required roughly 2000 head of cattle and two square leagues of land (fourteen square miles) to live comfortably. Foreign entrepreneurs came to the area to provide goods that Mexico couldn’t, and trading ships were taxed.[note 1]

Bear Flag Republic and statehood

Main article: Bear Flag Revolt

The exclusive land ownership in California by the approximate 9,000[8] Hispanics in California would soon end. John Marsh, owner of Rancho Los Meganos in Contra Costa County, had a lot to do with this. He sent letters to influential people in the eastern United States extolling the climate, soil and potential for agriculture in California, with the deliberate purpose of encouraging Americans to immigrate to California and lead to its becoming part of the United States. He succeeded. His letters were published in newspapers throughout the East, and started the first wagon trains rolling toward California. He also invited them to stay on his ranch until they could get settled, so the Rancho Los Meganos became the terminus of the California trail.[9]

This led to the Bear Flag Revolt in 1846 when about 30 settlers originally from the United States declared a republic in June 1846 and were enlisted and fighting under the U.S. flag by July 1846. Following the Mexican–American War of 1846–48, California was controlled by U.S. settlers organized under the California Battalion and the U.S. Navy's Pacific Squadron. After some minor skirmishes California was under U.S. control by January 1847 and formally annexed and paid for by the U.S. in 1848. By 1850 the over-100,000 population and rapidly growing California population gain due to the California gold rush and the large amount of gold being exported east gave California enough clout to choose its own boundaries, write its own constitution and be admitted to the Union as a free state in 1850 without going through territorial status as required for most other states.

In 1850 California had a non-Indian population of over 100,000.[10] The number of Indians living in California in 1850 has been estimated to be from 60,000 to 100,000. By 1850 the Mission Indian populations had largely succumbed to disease and abuse and only numbered a few thousand. California's 1852 state Census gives 31,266 Indian residents; but this is an under-count since there was little incentive and much difficulty in getting it more correct.[11]

County creation

Contra Costa County was one of the original 27 counties of California, created in 1850 at the time of statehood. The county was originally to be called Mt. Diablo County, but the name was changed prior to incorporation as a county. The county's Spanish language name means opposite coast, because of its location opposite San Francisco, in an easterly direction, on San Francisco Bay. Southern portions of the county's territory, including all of the bayside portions opposite San Francisco and northern portions of Santa Clara County, were given up to form Alameda County effective March 25, 1853.

The land titles in Contra Costa County may be traced to multiple subdivisions of a few original land grants. The grantee's family names live on in a few city and town names such as Martinez, Pacheco and Moraga and in the names of streets, residential subdivisions, and business parks. A few mansions from the more prosperous farms have been preserved as museums and cultural centers and one of the more rustic examples has been preserved as a working demonstration ranch, Borges Ranch.

1941–1945

During World War II, Richmond hosted one of the two Bay Area sites of Kaiser Shipyards and wartime pilots were trained at what is now Concord/Buchanan Field Airport. Additionally, a large Naval Weapons Depot and munitions ship loading facilities at Port Chicago remain active to this day, but with the inland storage facilities recently declared surplus, extensive redevelopment is being planned for this last large central-county tract. The loading docks were the site of a devastating explosion in 1944. Port Chicago was bought out and demolished by the Federal Government to form a safety zone near the Naval Weapons Station loading docks. At one time the Atlas Powder Company (subsequently closed) produced gunpowder and dynamite. The site of the former Atlas Powder Company is located at Point Pinole Regional Shoreline,[12] part of the East Bay Regional Parks District.[13]

Early postwar period

With the postwar baby boom and the desire for suburban living, large tract housing developers would purchase large central county farmsteads and develop them with roads, utilities and housing. Once mostly rural walnut orchards and cattle ranches, the area was first developed as low cost, large lot suburbs, with a typical low cost home being placed on a "quarter acre" (1,000 m²) lot — actually a little less at 10,000 square feet (930 m²). Some of the expansion of these suburban areas was clearly attributable to white flight from decaying areas of Alameda County and the consolidated city-county of San Francisco, but much was due to the postwar baby boom of the era creating demand for three and four bedroom houses with large yards that were unaffordable or unavailable in the established bayside cities.

Later postwar period (1955–1970)

A number of large companies followed their employees to the suburbs, filling large business parks. The establishment of a large, prosperous population in turn fostered the development of large shopping centers and created demand for an extensive supporting infrastructure including roads, schools, libraries, police, firefighting, water, sewage, and flood control.

Modern period

The establishment of BART, the modernization of Highway 24, and the addition of a fourth Caldecott Tunnel bore all served to reinforce the demographic and economic trends in the Diablo area, with cities such as Walnut Creek becoming edge cities.

The central county cities have in turn spawned their own suburbs within the county, extending east along the county's estuarine north shore; with the older development areas of Bay Point and Pittsburg being augmented by extensive development in Antioch, Oakley, and Brentwood.

The effects of the housing value crash (2008–2011) have varied widely throughout the county. Values of houses in prosperous areas with good schools have declined only modestly in value, while houses recently built outlying suburbs in the eastern county have experienced severe reductions in value, accelerated by high unemployment and consequent mortgage foreclosures, owner strategic walk-aways, and the too-rapid conversion of neighborhoods from owner-occupancy to rentals.

Geography

According to the U.S. Census Bureau, the county has a total area of 804 square miles (2,080 km2), of which 716 square miles (1,850 km2) is land and 88 square miles (230 km2) (11%) is water.[14]

Contra Costa County's physical geography is dominated by the bayside alluvial plain, the Oakland Hills–Berkeley Hills, several inland valleys, and Mount Diablo, an isolated 3,849-foot (1,173 m) upthrust peak at the north end of the Diablo Range of hills. The summit of Mount Diablo is the origin of the Mount Diablo Meridian and Base Line, on which the surveys of much of California and western Nevada are based.

The Hayward Fault Zone runs through the western portion of the county, from Kensington to Richmond. The Calaveras Fault runs in the south-central portion of the county, from Alamo to San Ramon. The Concord Fault runs through part of Concord and Pacheco, and the Clayton-Marsh Creek-Greenville Fault runs from Clayton at its north end to near Livermore. These slip-strike earthquake faults and the Diablo thrust fault near Danville are all considered capable of significantly destructive earthquakes and many lesser related faults are present in the area that cross critical infrastructure such as water, natural gas, and petroleum product pipelines, roads, highways, railroads, and BART rail transit.

National protected areas

Mount Diablo

Mount Diablo from the Shell Ridge Open Space
Main article: Mount Diablo

The most notable natural landmark in the county is 3,849 feet (1,173 m) Mount Diablo, at the northerly end of the Diablo Range. Mount Diablo and its neighboring North Peak are the centerpiece of Mt. Diablo State Park (MDSP), created legislatively in 1921 and rededicated in 1931 after land acquisitions had been completed. At the time this comprised a very small portion of the mountain.

In the 1960s the open space of the mountain was threatened with suburban development expanding from the surrounding valleys. In 1971, when MDSP included 6,788 acres (27.5 km2), the non-profit organization Save Mount Diablo, was formed and open space preservation accelerated. MDSP was the first of twenty-nine Diablo area parks and preserves created around the peaks, today totaling more than 89,000 acres (360 km2). These Diablo public lands stretch southeast and include the Concord Naval Weapons Station, Shell Ridge Open Space and Lime Ridge Open Spaces near Walnut Creek, to the State Park, and east to the Los Vaqueros Reservoir watershed and four surrounding East Bay Regional Park District preserves, including Morgan Territory Regional Preserve, Brushy Peak Regional Preserve, Vasco Caves Regional Preserve, and Round Valley Regional Preserves. The new Cowell Ranch State Park, and Black Diamond Mines Regional Preserve, are among the open spaces stretching back to the north. In this way the open spaces controlled by cities, the East Bay Regional Park District, Mount Diablo State Park, and various regional preserves now adjoin and protect most of the elevated regions of the mountain.

The name Mount Diablo is said to originate from an incident involving Spanish soldiers who christened a thicket ‘Monte del Diablo’ when natives they were pursuing apparently disappeared in the thicket. Anglo settlers later misunderstood the use of the word ‘monte’ (which can mean ‘mountain’, or ‘thicket’), and fastened the name on the most obvious local landmark.

Contra Costa County has become a Democratic stronghold, with even wealthy cities like Orinda and Walnut Creek voting Democratic in recent elections. The last Republican presidential candidate to win a majority in the county was Ronald Reagan in 1984.

In the United States House of Representatives, Contra Costa County is split between four congressional districts:[33]

In the State Assembly, Contra Costa County is split between four districts:

In the State Senate, the county is split between three districts:

According to the California Secretary of State, as of October 22, 2012, Contra Costa County has 556,351 registered voters, out of 703,217 eligible (79%). Of those, 275,757 (49.6%) are registered Democrats, 137,025 (24.6%) are registered Republicans, and 120,278 (21.6%) have declined to state a political party.[34] Democrats hold wide voter-registration advantages in all political subdivisions in Contra Costa County, except for the affluent cities of Danville and Clayton. The Democrats' largest registration advantage in Contra Costa is in the city of Richmond, wherein there are only 3,457 Republicans (7.9%) out of 43,689 registered voters compared to 29,792 Democrats (68.2%) and 8,649 voters who have declined to state a political party (19.8%).

Economy

Agriculture

The great rancheros of the Spanish period were divided and sold for agricultural uses, with intensively irrigated farming made possible in some areas by the development of canals that brought water from the eastern riverside portions of the county to the central portion. Other areas could used the more limited water available from local creeks and from wells. Orchards dominated where such water was available, while other, seasonally dry areas were used for cattle ranching. In central parts of the county walnuts were an especially attractive orchard crop, using the thin-shelled English Walnut branches grafted to the hardy and disease-resistant American Walnut root stock. In the Moraga region, pears dominated, and many old (but untended) roadside trees are still picked seasonally by passers-by. In eastern county, stone fruit, especially cherries, is still grown commercially, with seasonal opportunities for people to pick their own fruit for a modest fee.

Irrigation canals

The Contra Costa Canal, a concrete-lined and fenced irrigation canal still makes a loop through central county and provided industrial and agricultural grade water to farms and industry. While no longer used for extensive irrigation, it is still possible for adjoining landowners (now large suburban lot owners) to obtain pumping permits. Most of this water is destined for the heavy industry near Martinez. As with the railroad rights of way there is now an extensive public trail system along these canals.

Commuter railroads

The development of commuter railroads proceeded together with the subdivision of farms into parcels. In some cases, such as the development of Saranap, the same developer controlled both the railroad (Sacramento Northern) and the development. These early suburbanization developments were an extension of the earlier development of trolley car suburbs in what are now considered the highly urban environments of the near East Bay.

Heavy industry

View of the Shell Martinez oil refinery

Owing to its extensive waterfront on San Francisco, San Pablo, and Suisun bays the northwestern and northern segments have long been sites for heavy industry, including a number of still active oil refineries (particularly Chevron in Richmond, Shell Oil and Tesoro - in Martinez), chemical plants (Dow Chemical) and a once substantial integrated steel plant, Posco Steel (formerly United States Steel), now reduced to secondary production of strip sheet and wire. The San Joaquin River forms a continuation of the northern boundary turns southward to form the eastern boundary of the county. Some substantial Sacramento-San Joaquin Delta "islands" (actually leveed former marshes) are included in this corner of the county.

Housing

West County

The West County is the area near or on San Francisco and San Pablo bays. The housing stock in the region was extensively developed after the great San Francisco Earthquake of 1906. Much of the housing stock in these areas is becoming quite expensive. As an alternative to moving to either the expensive central county, or the too-distant East County, this area is becoming gentrified, with a mix of races and income levels — a character actively sought by some housing purchasers. The downside of this is a corresponding lack of affordable housing for those in lower paying service jobs — a problem endemic throughout the region. There has recently been a housing boom or tract housing in Richmond and also in the Hercules areas. These gentrifying areas are the most diverse in Contra Costa County.

Central county

Central county scene — Mount Diablo and portions of Concord, Pleasant Hill, and Walnut Creek, with former grasslands now an urban forest in low density suburbs with extensive business centers and residential buildings near BART locations (at the tall building groups). A recent (2007-8) development near the downtown Bart station consists of luxury apartments.>

The central part of the county is a valley traversed by Interstate 680 and Highway 24. The towns east of the hills, on or near Highway 24 and their surrounding areas (Lafayette, Moraga and Orinda) are collectively known as Lamorinda. The major central county cities along Interstate 680 are Martinez, Concord, Pleasant Hill, Walnut Creek, Danville, San Ramon, and unincorporated Alamo. Owing to the high quality of its public schools (due largely to both demographics and added support from prosperous parents), this area has become a magnet for well–off families with children. During the real estate boom, housing prices were driven to astounding levels. From 2007, home prices in the region have seen substantial decreases and the affordability rate has risen. During the real estate boom, the high price of homes and scarcity of land resulted in many speculators purchasing older, smaller homes and partially or completely tearing them down to construct larger homes.

In this way the central county region has become a mix of older suburbs, newer developments, small lot "infill" developments, and extensive shopping areas.

Lafayette Reservoir

East County

Lower cost modern tract developments continue along Suisun Bay in the "East County" towns of Pittsburg, Antioch, and Oakley - new "bedroom" communities" to serve the now "edge cities". The median income of a family in the two relatively affluent East County towns of Brentwood and Discovery Bay is approaching $100k/yr. placing them in the top fifteen percent of affluent towns in the United States. California Distinguished Schools, golf courses, vineyards, and upscale homes are found in Brentwood and Discovery Bay. Discovery Bay is based on a waterfront community of 3,500+ homes with private docks with access to the Sacramento-San Joaquin River Delta. Discovery Bay also features gated and non-gated "off-water" communities with homes from 1,400 square feet (130 m2) up to 4,700 square feet (440 m2). The Streets of Brentwood, an outdoor lifestyle retail center, opened in Brentwood in the Fall of 2008. The Streets of Brentwood's upscale shops include Banana Republic, Coldwater Creek, DSW Shoes, Jos. A. Bank, REI, Swarovski, Victoria’s Secret, and White House/Black Market. The only all-digital Rave Motion Pictures in the San Francisco Bay Area is located in the Streets of Brentwood.

In 2011, Vasco Road is undergoing further construction/improvement to reduce the driving time between East County/Brentwood and Livermore. Highway 4 is currently undergoing multimillion-dollar improvements that are scheduled to add lanes through Antioch and Pittsburg by 2015 to reduce the driving time between East County and Concord/Walnut Creek.

Urban decay at the fringes

Other cities in the once heavily industrialized northwestern and western waterfront areas such as Richmond have fallen on harder times, with Richmond having difficulty balancing its school budget.

County budget problems

Two forces have combined to create county budget problems peaking in 2008. First, (over a thirty-year period) rather than compensate police, medical, and firefighting personnel directly, very favorable health and retirement benefits were granted without proper actuarial examination, leading to unexpected (yet predictable) high costs as personnel age and ultimately retire with continued "first class" health and retirement benefits. Second, the collapse of the "housing bubble" has enabled purchasers of distressed properties (many of which are owned by banks and other mortgage holders) to petition for lower property assessments, in many cases reducing by half the revenue to the county for specific parcels. Continuing downturns in employment prospects (particularly in new housing construction) have further increased the needs for various social services. These deficits and demands, combined with a lack of support from a similarly stressed California state government and the United States Federal government have combined to require unpleasant choices to be made by county supervisors and county service providers in the allocation of limited resources in a time of increasing demand. The projected budget deficit is $45 million as of early 2011.[38] Perhaps more significantly, the total unfunded liability for retiree benefits is $2.4 billion.[39]

Technical innovators

In the 1970s and 1980s many small and innovative technical firms were started in this county, most of which are no longer present, having either failed, been absorbed into larger corporations, or having outgrown their original location are now elsewhere in the Bay Area.

Corporate headquarters

During the 1980s and early 1990s, many corporations that were formerly housed in the more central metropolitan area followed their employees by moving to large suburban and edge city office areas and office parks.

A number of large corporations now have headquarters in large developments along what is called the 680 corridor, that segment of Interstate Highway 680 that extends from Concord in the north to San Ramon in the south, continuing into inland Alameda County from Dublin to Pleasanton.

By the early 1990s, more square footage of office space had been built in the 680 corridor than in San Francisco's Financial District.

Redevelopment

There are currently political fights over the potential redevelopment of the county seat (Martinez), with long term residents and many elsewhere in the county concerned that it will lose its remaining small-town charm and utility in an effort to become more like the county's major recreational shopping center of Walnut Creek.

The inland portions of the Concord Naval Weapons Station have been declared surplus by the Federal government and this area is expected to provide what is likely the last opportunity to plan and build city-sized development within the central county. This area will become a portion of the city of Concord, and planners expect that development will be confined to the lower and flatter portions of the depot, with the remainder becoming a substantial addition to the county's open space. Much of the land to be developed is relatively flat grassland and the most prominent structures are ammunition bunkers that will be removed, so future uses of the property are largely unconstrained by previous uses.

Education

Contra Costa County Library is the county's library system.

Media

The city of Concord is served by the daily newspaper, the Contra Costa Times published by the Bay Area News Group-East Bay (part of the Media News Group, Denver, Colorado), with offices in Walnut Creek. The paper was originally a paper run and owned by the Lesher family. Since the death of Dean Lesher in 1993, the paper has had several owners.[40] The publisher also issues weekly local papers, such as the Concord Transcript, which is the local paper for Concord and nearby Clayton.

Transportation

Prior to 1903 most travel to central Contra Costa County was by boat or rail to Martinez on the northern waterfront and from there to the industrial areas east along the waterfront as well as farming regions to the south.

In 1903 the first tunnel through the Oakland hills (now Old Tunnel Road) was built, principally as a means of bringing hay by horse, mule, or ox-drawn wagons from central and eastern agricultural areas to feed the draft animals that provided the power to public and private transportation in the East Bay at the time. The tunnel exited in the hills high above the crossroads of Orinda with the road continuing on to Lafayette, Walnut Creek, and Danville. The road was just wide enough for one car in each direction, and had no shoulders.

In 1937 the two-bore Caldecott Tunnel for road vehicles was completed, making interior Contra Costa County much more accessible. After World War II the tunnels allowed waves of development to proceed, oriented toward Oakland rather than the northern shoreline, and the northern shoreline cities began to decline. The tunnel has since been augmented with an additional bore, with the central bore reversed in direction to accommodate commute traffic. Owing to extensive reverse commuting and general increases in traffic, a fourth bore is currently under construction.

Major highways

Mass transit

Airports

The county also has two airports that are not currently providing passenger service:

Railroads

The western termini of several original transcontinental railroad routes have been located in Oakland, in Alameda County, Including Union Pacific, Southern Pacific, and Santa Fe railroads. From Oakland, there are two primary routes east:

Formed in 1909, the Oakland Antioch Railway was renamed the Oakland Antioch & Eastern Railway in 1911. It extended through a 3,400-foot (1,000 m) tunnel in the Oakland Hills, from Oakland to Walnut Creek, Concord and on to Bay Point.

The current owner of the Santa Fe Railroad's assets, BNSF Railway has the terminus of its transcontinental route in Richmond. Originally built by the San Francisco and San Joaquin Valley Railroad in 1896, the line was purchased by the Atchison, Topeka and Santa Fe Railway shortly thereafter. The line leaves Richmond through industrial and residential parts of West County before striking due east through Franklin Canyon and Martinez on its way to Stockton, Bakersfield and Barstow.

These railroads spurred the development of industry in the county throughout the late 19th and early 20th centuries, particularly driving development of the Standard Oil (now Chevron) refinery and port complex in Richmond.

There were a large number of short lines in the county between the late 19th century and the early 20th century. The rights of way of a number of these railroads also served as utility rights of way, particularly for water service, and so were preserved, and in the late 20th century enhanced as walking, jogging, and bicycle riding trails in the central portion of the county.

Alternative commute infrastructure

Contra Costa County also provides alternative commute options for those without cars or who choose to commute in an environmentally friendly manner. The Bay Area Rapid Transit BART train network stops in many cities in the County, and the County Connection bus service serves areas not immediately adjacent to BART stations. In addition, the local transportation demand management organization 511 Contra Costa offers services to County residents who wish to switch from single occupancy vehicle driving to greener modes.
