Aliso Creek (Los Angeles County)
Aliso Creek (also Aliso Canyon Wash or Aliso Wash) is a major tributary of the Upper Los Angeles River in the Santa Susana Mountains in Los Angeles County and western San Fernando Valley in the City of Los Angeles, California. It has a watershed of . It is the second major tributary, after Browns Canyon Wash−Creek, to enter the Los Angeles River downstream of its headwaters at the confluence of Bell Creek and Arroyo Calabasas in Canoga Park. Course The stream runs about from Aliso Canyon below Oat Mountain in the Santa Susana Mountains to its confluence with the Los Angeles River. During its first , it is a free-flowing stream mostly contained within Aliso Canyon Park and Eddlestone Park on the border of Granada Hills and Porter Ranch. After it passes under State Route 118 (Simi Valley Freeway) and enters Northridge, it empties into a retention basin and from there on is encased in a concrete flood control channel flowing southward across the San Fernando Valley.

Reseda Boulevard
Reseda Boulevard, named Reseda Avenue until May 1929, is a major north–south arterial road that runs through the western San Fernando Valley region of Los Angeles, California. Reseda Boulevard runs approximately from the Santa Monica Mountains at the Marvin Braude Mulholland Gateway Park in the south to the Santa Susana Mountains and Porter Ranch in the north. It passes through the community of Tarzana, passes Mulholland Park gated community and El Caballero Country Club, then continues into the flats of the Valley through the communities of Reseda and Northridge, passes the campus of California State University Northridge, and ends at Porter Ranch. The epicenter of the 1994 Northridge earthquake was approximately one block west of the Boulevard, in its namesake community of Reseda. Damage occurred throughout the San Fernando Valley though areas of more widespread destruction followed along the boulevard's northern course, including an apartment building which stood at th ...

Right Bank
In geography, a bank is the land alongside a body of water. Different structures are referred to as ''banks'' in different fields of geography, as follows. In limnology (the study of inland waters), a stream bank or river bank is the terrain alongside the bed of a river, creek, or stream. The bank consists of the sides of the channel, between which the flow is confined. Stream banks are of particular interest in fluvial geography, which studies the processes associated with rivers and streams and the deposits and landforms created by them. Bankfull discharge is a discharge great enough to fill the channel and overtop the banks. The descriptive terms ''left bank'' and ''right bank'' refer to the perspective of an observer looking downstream; a well-known example of this being the sections of Paris as defined by the river Seine. The shoreline of ponds, swamps, estuaries, reservoirs, or lakes are also of interest in limnology and are sometimes referred to as banks. The grade ...

Flood Control Channel
Flood control channels are large and empty basins which let water flow in and out (except during flooding) or dry channels that run below the street levels of some larger cities, so that if and when a flood occurs, the water will run into these channels, and eventually drain into a river or other body of water. Flood channels are sometimes built on the former courses of waterways as a way to reduce flooding. Levees Flood control channels are not to be confused with watercourses which are simply confined between levees. These structures may be made entirely of concrete, with concrete sides and an exposed bottom, with riprap sides and an exposed bottom, or completely unlined. They often contain grade control sills or weirs to prevent erosion and maintain a level streambed. Distribution By definition, flood control channels range from the size of a street gutter to a few hundred or even a few thousand feet wide in some rare cases. Flood control channels are found in most heavily de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retention Basin
A retention basin, sometimes called a wet pond, wet detention basin, or stormwater management pond (SWMP), is an artificial pond with vegetation around the perimeter and a permanent pool of water in its design. It is used to manage stormwater runoff, for protection against flooding, for erosion control, and to serve as an artificial wetland and improve the water quality in adjacent bodies of water. It is distinguished from a detention basin, sometimes called a "dry pond", which temporarily stores water after a storm, but eventually empties out at a controlled rate to a downstream water body. It also differs from an infiltration basin which is designed to direct stormwater to groundwater through permeable soils. Wet ponds are frequently used for water quality improvement, groundwater recharge, flood protection, aesthetic improvement, or any combination of these. Sometimes they act as a replacement for the natural absorption of a forest or other natural process that was lost wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northridge, Los Angeles
Northridge is a neighborhood in the San Fernando Valley region of the City of Los Angeles. The community is home to California State University, Northridge, and the Northridge Fashion Center. Originally named Zelzah by settlers in 1908, the community was renamed North Los Angeles in 1929 but the appellation sometimes caused confusion between North Hollywood and Los Angeles. In 1938, civic leader Carl S. Dentzel decided to rename the community to Northridge Village, which morphed into modern-day Northridge. The Northridge area can trace its history back to the Tongva people and later to Spanish explorers. It was sold by the Mexican governor Pio Pico to Eulogio de Celis, whose heirs divided it for resale. Population The 2000 U.S. census counted 57,561 residents in the Northridge neighborhood—or , among the lowest population densities for the city. In 2008, the city estimated that the population had increased to 61,993. In 2000 the median age for residents was 32, about averag ...

Porter Ranch, Los Angeles
Porter Ranch is a suburban neighborhood in the northwest San Fernando Valley region of the City of Los Angeles, California. History New home construction that was completed in the Porter Ranch area in the 1990s–2000s, including the Renaissance Summit development, was mired in controversy and Los Angeles politics in the late 1980s and early 1990s. Existing residents of the Porter Ranch area feared the increased traffic that would be brought by the planned building of an area commercial complex to service the new homes being built. Developments were also criticized for destroying the natural beauty of the brush and wild areas that inhabited the space before the houses were built. However, Shapell Homes, a company founded by Nathan Shapell, a major Los Angeles builder, brought together powerful Los Angeles political figures to support the new home building. Aliso Canyon Bridge In the late 80s, there was an attempt to connect Sesnon Boulevard, the road that flanks the north side ...
