Early contact was fleeting and mostly peaceful, however, in the late 1700s, Spanish cattle were grazed the territory of the Saklan and their neighbors. The Saklans were one of the few groups who mounted resistance against the efforts of the Spanish to convert them to Christianity. Christian natives were sent to the Saklans to convince them to give up their culture and come to Mission San Jose; they were killed by the Saklans who wanted nothing to do with the Spanish way of life. A punitive expedition was sent to the area in 1797 to repress the Saklans, and a battle was fought in modern-day Lafayette.

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 m<sup>2</sup>) lot — actually a little less at 10,000 square feet (930 square metres). Some of the expansion of these suburban areas was clearly attributable to <a href="/wiki/White_flight" title="White flight">white flight</a> from decaying areas of <a href="/wiki/Alameda_County,_California" title="Alameda County, California">Alameda County</a> and the <a href="/wiki/Consolidated_city-county" title="Consolidated city-county">consolidated city-county</a> of <a href="/wiki/San_Francisco,_California" class="mw-redirect" title="San Francisco, California">San Francisco</a>, but much was due to the postwar <a href="/wiki/Post-World_War_II_baby_boom" class="mw-redirect" title="Post-World War II baby boom">baby boom</a> of the era creating demand for three- and four-bedroom houses with large yards that were unaffordable or unavailable in the established bayside cities. </p><p>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. </p><p>The establishment of the <a href="/wiki/Bay_Area_Rapid_Transit" title="Bay Area Rapid Transit">Bay Area Rapid Transit</a> (BART) system, the modernization of <a href="/wiki/California_State_Route_24" title="California State Route 24">Highway 24</a>, and the addition of a fourth <a href="/wiki/Caldecott_Tunnel" title="Caldecott Tunnel">Caldecott Tunnel</a> bore all served to reinforce the demographic and economic trends in the <a href="/wiki/Diablo_Valley" title="Diablo Valley">Diablo Valley</a> area, with cities such as <a href="/wiki/Walnut_Creek,_California" title="Walnut Creek, California">Walnut Creek</a> and <a href="/wiki/Concord,_California" title="Concord, California">Concord</a> becoming <a href="/wiki/Edge_city" title="Edge city">edge cities</a>. </p><p>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 <a href="/wiki/Bay_Point,_California" title="Bay Point, California">Bay Point</a> and <a href="/wiki/Pittsburg,_California" title="Pittsburg, California">Pittsburg</a> being augmented by extensive development in <a href="/wiki/Antioch,_California" title="Antioch, California">Antioch</a>, <a href="/wiki/Oakley,_California" title="Oakley, California">Oakley</a>, and <a href="/wiki/Brentwood,_California" title="Brentwood, California">Brentwood</a>. </p><p>The effects of the housing value crash (2008–2011) varied widely throughout the county. Values of houses in prosperous areas with good schools declined only modestly in value, while houses recently built in outlying suburbs in the eastern part of the county experienced severe reductions in value, accelerated by high unemployment and consequent mortgage foreclosures, owner <i>strategic walk-aways</i>, and the too-rapid conversion of neighborhoods from owner-occupancy to rentals.

Diablo State Park</a> (MDSP), created legislatively in 1921 and rededicated in 1931 after land acquisitions had been completed. At the time this park comprised a very small portion of the mountain. </p><p>In the 1960s, suburban development expanding from the surrounding valleys began to threaten the open space of the mountain. In 1971, MDSP consisted of 6,788 acres (27.5 km<sup>2</sup>). That year, concerned residents formed the non-profit organization <a href="/w/index.php?title=Save_Mount_Diablo&action=edit&redlink=1" class="new" title="Save Mount Diablo (page does not exist)">Save Mount Diablo</a> to raise funds and awareness to protect more open space. In addition to encouraging acquisition by the state and local authorities, SMD started fundraising and acquiring properties to transfer to the park. MDSP was the first of twenty-nine Diablo-area parks and preserves that have been created around the peaks; today these preserves protect more than 89,000 acres (360 km<sup>2</sup>). </p><p>These Diablo public lands stretch southeast and include the <a href="/wiki/Concord_Naval_Weapons_Station" title="Concord Naval Weapons Station">Concord Naval Weapons Station</a>, <a href="/w/index.php?title=Shell_Ridge_Open_Space&action=edit&redlink=1" class="new" title="Shell Ridge Open Space (page does not exist)">Shell Ridge Open Space</a> and <a href="/w/index.php?title=Lime_Ridge_Open_Space&action=edit&redlink=1" class="new" title="Lime Ridge Open Space (page does not exist)">Lime Ridge Open Spaces</a> near Walnut Creek, to the State Park, and east to the <a href="/wiki/Los_Vaqueros_Reservoir" title="Los Vaqueros Reservoir">Los Vaqueros Reservoir</a> watershed and four surrounding East Bay Regional Park District preserves, including <a href="/wiki/Morgan_Territory_Regional_Preserve" title="Morgan Territory Regional Preserve">Morgan Territory Regional Preserve</a>, <a href="/wiki/Brushy_Peak_Regional_Preserve" title="Brushy Peak Regional Preserve">Brushy Peak Regional Preserve</a>, <a href="/wiki/Vasco_Caves_Regional_Preserve" title="Vasco Caves Regional Preserve">Vasco Caves Regional Preserve</a>, and <a href="/wiki/Round_Valley_Regional_Preserve" title="Round Valley Regional Preserve">Round Valley Regional Preserve</a>.

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. </p><p>The name Mount Diablo is said to originate from an incident involving Spanish soldiers who christened a thicket as <i>Monte del Diablo</i> when natives they were pursuing apparently disappeared into the thicket. Anglo settlers later misunderstood the use of the word 'monte' (which can mean 'mountain', or 'thicket'), and applied the name to the most obvious local landmark. </p><p>According to the <i>Contra Costa Times</i>, in 2011, there were rumors that Contra Costa County was going to rename the mountain as "Mt. Ronald Reagan" or "Mt. Reagan", after the former US president and California governor. Residents have generated multiple petitions to change the name of the mountain, one in 2005 and another in 2011, but these were not successful. </p> <div class="mw-heading mw-heading2"><h2

<p>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.

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 <a href="/wiki/Moraga,_California" title="Moraga, California">Moraga</a> region, pears dominated, and many old (but untended) roadside trees are still picked seasonally by passers-by.

First, rather than compensate police, medical, and firefighting personnel directly, health and retirement benefits were granted without proper actuarial examination, leading to unexpected but predictable high costs as personnel aged and ultimately retired with continued "first class" health and retirement benefits. Second, the collapse of the "housing bubble" enabled purchasers of distressed properties — many of which were 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 further increased the needs for various social services.

The tunnel exited in the hills high above the crossroads of <a href="/wiki/Orinda,_California" title="Orinda, California">Orinda</a> with the road continuing on to <a href="/wiki/Lafayette,_California" title="Lafayette, California">Lafayette</a>, <a href="/wiki/Walnut_Creek,_California" title="Walnut Creek, California">Walnut Creek</a>, and <a href="/wiki/Danville,_California" title="Danville, California">Danville</a>. The road was just wide enough for one car in each direction and had no shoulders. </p><p>In 1937, the two-bore <a href="/wiki/Caldecott_Tunnel" title="Caldecott Tunnel">Caldecott Tunnel</a> 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 <a href="/wiki/Oakland" class="mw-redirect" title="Oakland">Oakland</a> rather than the northern shoreline, and the northern shoreline cities began to decline. The tunnel has since been augmented with a third bore, completed in 1964, and a fourth, completed in 2013. </p> <div class="mw-heading mw-heading3"><h3 id="Major_highways">Major highways</h3><span
