Northbrae, Berkeley, California
Northbrae, Berkeley, California is an affluent neighborhood in Berkeley, California built as part of the northern expansion of North Berkeley. Its border is Solano Avenue to the North, Spruce Street to the East, the Albany city limits to the West, and Hopkins Street, Yolo Avenue, and Eunice Street to the south. It's bordered by the two commercial districts on Solano Avenue and Hopkins Street, as well as hilly terrain made up of volcanic rock, rhyolite, and 136 stairways carved into the landscape. The neighborhood is visibly distinct for its pink sidewalks and many stone pillars topped with concrete globes denoting street names. The central hub of Northbrae is the Fountain at the Circle, a water fountain designed by the head architect of the University of California surrounded by terra cotta roundabout and stairwell. Northbrae made it into the American Planning Association's list of Great Places in America in 2011. History After a 1906 earthquake along the western coast, about ...

Rhyolite
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent to granite. Rhyolitic magma is extremely viscous, due to its high silica content. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been extensively used for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil amendment. Description Rhyolite i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northbrae Tunnel
The Northbrae Tunnel, also referred to as the Solano Avenue Tunnel, was built as a commuter electric railroad tunnel in the northern part of Berkeley, California, and was later converted to street use. In 1910 the Southern Pacific Railroad (SP) was electrifying its steam-engine drawn ferry-train line (to San Francisco) from Oakland Pier via Shattuck Avenue to Vine Street in Berkeley and extending it north along the base of the Berkeley Hills to newly developing neighborhoods of Berkeley at Northbrae and Thousand Oaks. The route chosen was Henry Street and Sutter Street to its intersection with Hopkins. At this point a ridge carrying Marin and Los Angeles Avenues blocked the way. After investigating (1) a route around the ridge and (2) a cut through the ridge with bridges over it, it was decided to use the route of the cut but make it a tunnel instead, under Marin and Los Angeles Avenues just west of their intersection with The (Marin) Circle. The cut-and-cover method of tunnel con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Planning Association
The American Planning Association (APA) is a professional organization representing the field of urban planning in the United States. APA was formed in 1978, when two separate professional planning organizations, the American Institute of Planners and the American Society of Planning Officials, were merged into a single organization. The American Institute of Certified Planners is now the organization's professional branch. Functions Like many professional organizations, the American Planning Association's main function is to serve as a forum for the exchange of ideas between people who work in the field of urban planning. The organization keeps track of the various improvement efforts underway around the country, which may include the improvement or construction of new parks, highways and roads, or residential developments. The organization is also a starting point for people looking for employment. The association also publishes the ''Journal of the American Planning Asso ...

1906 San Francisco Earthquake
At 05:12 Pacific Standard Time on Wednesday, April 18, 1906, the coast of Northern California was struck by a major earthquake with an estimated moment magnitude of 7.9 and a maximum Mercalli intensity of XI (''Extreme''). High-intensity shaking was felt from Eureka on the North Coast to the Salinas Valley, an agricultural region to the south of the San Francisco Bay Area. Devastating fires soon broke out in San Francisco and lasted for several days. More than 3,000 people died, and over 80% of the city was destroyed. The events are remembered as one of the worst and deadliest earthquakes in the history of the United States. The death toll remains the greatest loss of life from a natural disaster in California's history and high on the lists of American disasters. Tectonic setting The San Andreas Fault is a continental transform fault that forms part of the tectonic boundary between the Pacific Plate and the North American Plate. The strike-slip fault is characterized by ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Beaux Arts Style
Beaux-Arts architecture ( , ) was the academic architectural style taught at the École des Beaux-Arts in Paris, particularly from the 1830s to the end of the 19th century. It drew upon the principles of French neoclassicism, but also incorporated Renaissance and Baroque elements, and used modern materials, such as iron and glass. It was an important style in France until the end of the 19th century. History The Beaux-Arts style evolved from the French classicism of the Style Louis XIV, and then French neoclassicism beginning with Style Louis XV and Style Louis XVI. French architectural styles before the French Revolution were governed by Académie royale d'architecture (1671–1793), then, following the French Revolution, by the Architecture section of the Académie des Beaux-Arts. The Academy held the competition for the Grand Prix de Rome in architecture, which offered prize winners a chance to study the classical architecture of antiquity in Rome. The formal neoclassicis ...

Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia. Quartz is the mineral defining the val ...
