Civic6 is a programed bridge straddling the LA River. It is
located at LAs infrastructural nexus. This nexus includes heavy
rails, riparian habitats, power-lines, and vehicular circulation
routes. Civic6 will replace the structurally unsound 6th street
bridge while preserving its alignment and maximum roadway
elevation.
The program is inserted above the vehicular right-of-way and
centered above the river channel. Civic6 houses a Science Discovery
Center, a restaurant, a theater and several break out spaces. It is
situated to utilize existing seasonal water and wind fl ows, to
interact with the micro-climate of the channel, and to improve
dialog between pedestrian and river channel.
The project combines environmental control strategies with
regional infrastructural needs; focusing on daylighting,
ventilation, and hydroelectric power production. The project thus
becomes the gateway from east LA to Downtown physically connecting
the areas two primary open spaces; the LA River & Hollenbeck
Park.
MUSEVI a new elevated museum complete with an outdoor
amphitheater at its base is phase one of a Paseo Tabasco Master
Plan.
Beginning with MUSEVI, this multi-phased master plan for Paseo
Tabasco aims to punctuate the citys existing public spaces through
contemporary design and environmental improvement.
This phase will also serve to catalyze private development along
the primary road, mitigate traffic issues and rejuvenate the public
spaces.

LA site history
3.8 million people share las water18% of la water comes from the
eastern sierras71% of the metropolitan water supply is purchased
From the MWD52% power comes from coal fired plants in Utah,
Arizona, and Nevada
Los Angeles started with the Zanja System which is a collection
of gravity feed waterways and ditches. These diversion type ditches
provided the life blood for the Old Pueblo De Los Angeles.
Felipe De Nuece who was the first governor of California chose
LAs current location because of its ability to be irrigated. These
farmers were charged with the responsibility of maintaining the
dams and waterways for agriculture production.
In 1849 water wheels become a power generation method used to
power the first flower mill and local newspaper. It wasnt until
1860 that the City of Los Angeles Water Company completed its first
water system. On February 3, 1902, the city formally took ownership
of the first Los Angeles municipal water works system.
The population of Los Angeles leaped from 5,728 in 1870 to
102,479 by 1900. Along with inherent growth problems, the city
faced a serious water shortage.
William Mulholland, its first superintendent and chief engineer,
began enlarging the LA River System. Mulholland conceived of an
engineering marvel: a plan to build an aqueduct system that would
transport water from the Eastern Sierra mountains to Los
Angeles
Mulhollands dream was realized in 1913 when water from the
Eastern Sierra Nevada came gushing down the cascades into the Los
Angeles Basin. As Los Angeles population grew by leaps and bounds,
the Department built a 177-mile second aqueduct from the Owens
Valley, completed in 1970, which had capacity to bring an
additional annual flow of 152,000 acre-feet to Los Angeles
The Los Angeles Aqueduct did more than supply water to the city.
It also brought power to Los Angeles. During the building of the
aqueduct, the citys first power plantlocated at Division Creek and
built in 1905was brought on-line to supply hydroelectric power for
the aqueducts construction. The Bureau of Los Angeles Aqueduct
Power (forerunner to the Department of Water and Power) was
established in 1909, with Ezra F. Scatter good named as chief
electrical engineer.
As more people moved to Los Angeles, the LADWP joined
partnerships to bring power from Boulder Dam (now Hoover Dam). A
266-mile transmission line was erected from the dam to downtown Los
Angeles. It was the first time the Department ventured out of state
to bring power, and set a precedent to join consortium to build
power plants in Utah, Arizona and Nevada.
After World War II, the citys population grew to 2 million
people, and with it, so did the LADWPs power base. In the 1950s and
1960s, the LADWP added a number of power plants, including the
Owens River Gorge Hydroelectric Project, Valley Generating Station,
Scatter good Generating Station, and Haynes Generation Station to
accommodate power needs. info from Department of Water & Power

mixed, proper aeration and chemical controls-The lake does not lose
water to seepage, thanks to a recovery system that pumps water back
into the lake-Evaporation costs Town Lake about the same amount of
