Marina (San Francisco)
The Marina District is a neighborhood located in San Francisco, California. The neighborhood sits on the site of the 1915 Panama–Pacific International Exposition, staged after the 1906 San Francisco earthquake to celebrate the reemergence of the city. Aside from the Palace of Fine Arts (POFA), all other buildings were demolished to make the current neighborhood. The Marina currently has the highest non-Hispanic white resident percentage of any recognized neighborhood in San Francisco. Location The area is bounded to the east by Van Ness Avenue and Fort Mason; on the west by Lyon Street and the Presidio National Park; on the south by Cow Hollow and Lombard St, which bisects the southern edge of the Marina District. The northern half of the Marina is a shoreline of the San Francisco Bay, and features the Marina Green, a park adjacent to the municipal boat marina from which the neighborhood takes its name.

Neighborhoods In San Francisco
San Francisco, in the US state of California, has both major, well-known neighborhoods and districts as well as smaller, specific subsections and developments. While there is considerable fluidity among the sources, one guidebook identifies five major districts, corresponding to the four quadrants plus a south central district. These five broad districts, counterclockwise are: Central/downtown, Richmond, Sunset, Upper Market and beyond (south central) and Bernal Heights/Bayview and beyond (southeast). Within each of these five districts are located major neighborhoods, and again there is considerable fluidity seen in the sources. The San Francisco Planning Department officially identifies 36 neighborhoods. Within these 36 official neighborhoods are a large number of minor districts, some of which are historical, and some of which are overlapping. Some of San Francisco's neighborhoods are also officially designated as " cultural districts." Alamo Square Alamo Square is a subset o ...

1989 Loma Prieta Earthquake
The 1989 Loma Prieta earthquake occurred on California's Central Coast on October 17 at local time. The shock was centered in The Forest of Nisene Marks State Park in Santa Cruz County, approximately northeast of Santa Cruz on a section of the San Andreas Fault System and was named for the nearby Loma Prieta Peak in the Santa Cruz Mountains. With an magnitude of 6.9 and a maximum Modified Mercalli intensity of IX (''Violent''), the shock was responsible for 63 deaths and 3,757 injuries. The Loma Prieta segment of the San Andreas Fault System had been relatively inactive since the 1906 San Francisco earthquake (to the degree that it was designated a seismic gap) until two moderate foreshocks occurred in June 1988 and again in August 1989. Damage was heavy in Santa Cruz County and less so to the south in Monterey County, but effects extended well to the north into the San Francisco Bay Area, both on the San Francisco Peninsula and across the bay in Oakland.

Soil Liquefaction
Soil liquefaction occurs when a cohesionless saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress such as shaking during an earthquake or other sudden change in stress condition, in which material that is ordinarily a solid behaves like a liquid. In soil mechanics, the term "liquefied" was first used by Allen Hazen in reference to the 1918 failure of the Calaveras Dam in California. He described the mechanism of flow liquefaction of the embankment dam as: The phenomenon is most often observed in saturated, loose (low density or uncompacted), sandy soils. This is because a loose sand has a tendency to compress when a load is applied. Dense sands, by contrast, tend to expand in volume or 'dilate'. If the soil is saturated by water, a condition that often exists when the soil is below the water table or sea level, then water fills the gaps between soil grains ('pore spaces'). In response to soil compressing, the po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Reclamation
Land reclamation, usually known as reclamation, and also known as land fill (not to be confused with a waste landfill), is the process of creating new land from oceans, seas, riverbeds or lake beds. The land reclaimed is known as reclamation ground or land fill. In some jurisdictions, including parts of the United States, the term "reclamation" can refer to returning disturbed lands to an improved state. In Alberta, Canada, for example, reclamation is defined by the provincial government as "The process of reconverting disturbed land to its former or other productive uses." In Oceania, it is frequently referred to as land rehabilitation. History One of the earliest large-scale projects was the Beemster Polder in the Netherlands, realized in 1612 adding of land. In Hong Kong the Praya Reclamation Scheme added of land in 1890 during the second phase of construction. It was one of the most ambitious projects ever taken during the Colonial Hong Kong era.Bard, Solomon. 002 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marina Green
The Marina Green in San Francisco, California, is a expanse of grass between Fort Mason and the Presidio. It is adjacent to San Francisco Bay, and this location provides good views of the Golden Gate Bridge, Angel Island, Alcatraz Island, and parts of Marin County. Houses built mostly in the 1920s and 1930s line Marina Boulevard, the southern boundary of the Marina Green. Many of these houses have large bay windows, and Herb Caen, the late San Francisco newspaper columnist, often made references to the immaculate furnishings behind these windows. In the past, a railroad track along the southern edge of the Marina Green allowed the San Francisco Belt Railroad to serve the Presidio. Adjacent to the Marina Green is a marina, home to the St. Francis Yacht Club and the Golden Gate Yacht Club. The San Francisco Bay Trail runs through the green. Prior to the 1906 earthquake, this area was a tidal marsh. After the earthquake, much of the resulting rubble was dumped here. Later, to pr ...

San Francisco Bay
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the bay meas ...

Presidio Of San Francisco
The Presidio of San Francisco (originally, El Presidio Real de San Francisco or The Royal Fortress of Saint Francis) is a park and former U.S. Army post on the northern tip of the San Francisco Peninsula in San Francisco, California, and is part of the Golden Gate National Recreation Area. It had been a fortified location since September 17, 1776, when New Spain established the presidio to gain a foothold in Alta California and the San Francisco Bay. It passed to Mexico in 1820, which in turn passed it to the United States in 1848. As part of a 1989 military reduction program under the Base Realignment and Closure ( BRAC) process, Congress voted to end the Presidio's status as an active military installation of the U.S. Army. On October 1, 1994, it was transferred to the National Park Service, ending 219 years of military use and beginning its next phase of mixed commercial and public use. In 1996, the United States Congress created the Presidio Trust to oversee and manage the in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Mason
Fort Mason, in San Francisco, California originated as a coastal defense site during the American Civil War. The nucleus of the property was owned by John C. Frémont and disputes over compensation by the United States continued into 1968. In 1882 the defenses were named for Richard Barnes Mason, a military governor before statehood. Fort Mason became the headquarters for an Army command that included California and the Hawaiian Islands from 1904 to 1907. In 1912 the Army began building a port facility with piers and warehouses to be a home base for ships of the Army Transport Service serving Alaska, Hawaii, the Philippines and other Pacific Army posts and focus of Army supply for the Pacific. On 6 May 1932 that port facility was designated the San Francisco Port of Embarkation, modeled on the New York Port of Embarkation which supplied U.S. Army forces in World War I, to serve the Pacific. Fort Mason then became both the headquarters of the command that was the San Francisco Po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
