Claremont Tunnel
Claremont Tunnel, also known as the Claremont Water Tunnel is a utility tunnel in Alameda County, in the U.S. state of California near the historic Claremont Hotel. The tunnel crosses the Hayward Fault and carries water for 800,000 EBMUD customers. History The Claremont Tunnel was built in 1929. After the Loma Prieta earthquake in 1989, EBMUD began studying the potential effect of a large seismic event along the Hayward Fault. In the worst-case scenario, slip along the fault would sever the tunnel, disrupting the water supply to approximately 50 to 70% (800,000) of EBMUD's customers for up to six months. In response, EBMUD approved a $189 million Seismic Improvement Plan in 1994, which included seismic upgrades to the Claremont Tunnel. Seismic upgrades began in 2004 and completed in 2007. Design The original tunnel connects the EBMUD treatment plant in Orinda with the distribution system west of the Oakland Hills. It featured a bore square with a mostly unreinforced concr ...

Alameda County, California
Alameda County ( ) is a county located in the U.S. state of California. As of the 2020 census, the population was 1,682,353, making it the 7th-most populous county in the state and 21st most populous nationally. The county seat is Oakland. Alameda County is in the San Francisco Bay Area, occupying much of the East Bay region. The Spanish word ''alameda'' means either "a grove of poplars...or a tree lined street." The name was originally used to describe the Arroyo de la Alameda. The willow and sycamore trees along the banks of the river reminded the early Spanish explorers of a road lined with trees. Although a strict translation to English might be "Poplar Grove Creek," the name of the principal stream that flows through the county is now simply "Alameda Creek." Alameda County is part of the San Francisco–Oakland–Berkeley, CA Metropolitan Statistical Area, and the San Jose–San Francisco–Oakland, CA Combined Statistical Area. History The county was formed on Mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Claremont Hotel & Spa
Claremont Club & Spa, A Fairmont Hotel is a historic hotel situated at the foot of Claremont Canyon in the Berkeley Hills and located in the Claremont district, near the intersection of Claremont Avenue and Ashby Avenue; the site straddles the city limits of Berkeley and Oakland.

Hayward Fault
The Hayward Fault Zone is a right-lateral strike-slip geologic fault zone capable of generating destructive earthquakes. This fault is about long, situated mainly along the western base of the hills on the east side of San Francisco Bay. It runs through densely populated areas, including Richmond, El Cerrito, Berkeley, Oakland, San Leandro, Castro Valley, Hayward, Union City, Fremont, and San Jose. The Hayward Fault is parallel to the San Andreas Fault, which lies offshore and through the San Francisco Peninsula. To the east of the Hayward Fault lies the Calaveras Fault. In 2007, the Hayward Fault was discovered to have merged with the Calaveras Fault east of San Jose at a depth of , with the potential of creating earthquakes much larger than previously anticipated. Some geologists have suggested that the Southern Calaveras should be renamed as the Southern Hayward. North of San Pablo Bay is the Rodgers Creek Fault, which was shown in 2016 to be linked with the Hayward ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. ...

New Austrian Tunnelling Method
The New Austrian tunneling method (NATM), also known as the sequential excavation method (SEM) or sprayed concrete lining method (SCL), is a method of modern tunnel design and construction employing sophisticated monitoring to optimize various wall reinforcement techniques based on the type of rock encountered as tunneling progresses. This technique first gained attention in the 1960s based on the work of Ladislaus von Rabcewicz, Leopold Müller, and Franz Pacher between 1957 and 1965 in Austria. The name NATM was intended to distinguish it from earlier methods, with its economic advantage of employing inherent geological strength available in the surrounding rock mass to stabilize the tunnel wherever possible rather than reinforcing the entire tunnel. NATM/SEM is generally thought to have helped revolutionise the modern tunneling industry. Many modern tunnels have used this excavation technique. The works built by the Sequential Excavation Method are very attractive from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tunnels In The San Francisco Bay Area
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. Tun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
