LA site history

Civic6 is a programed bridge straddling the LA River. It is located at LA’s 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 it’s alignment and maximum roadway elevation.

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.

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 flows, to interact with the micro-climate of the channel, and to improve dialog between pedestrian and river channel.

Felipe De Nuece who was the first governor of California chose LA’s 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.

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.

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.

Tempe town lake Concept for lake created in 1966 at Arizona State University Opened Nov. 7, 1999 220 surface acres – 2 miles long 800-1,200 feet wide Average depth 12.5 feet, ranging from 7 to 19 feet Initial Construction costs: $45,532,196 Private developers are absorbing $26.9 million of these costs Water -Capacity is about 3,000 acre-feet or 977 million gallons -Water to keep the lake full comes from reclaimed water, recharge and recovery and water exchanges -Water quality is maintained by keeping the water well 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 water used by two golf courses each year or consumed by an 1,000-acre alfalfa field

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 Mulholland’s 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

In 1849 water wheels become a power generation method used to power the first flower mill and local newspaper. It wasn’t 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.

more production

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 city’s first power plant— located at Division Creek and built in 1905—was brought on-line to supply hydroelectric power for the aqueduct’s 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.

less production

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 city’s population grew to 2 million people, and with it, so did the LADWP’s 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 Los Angeles

Beginning with MUSEVI, this multi-phased master plan for Paseo Tabasco aims to punctuate the city’s existing public spaces through contemporary design and environmental improvement.

3.8 million people share la’s water 18% of la water comes from the eastern sierras 71% of the metropolitan water supply is purchased From the MWD 52% power comes from coal fired plants in Utah, Arizona, and Nevada

This phase will also serve to catalyze private development along the primary road, mitigate traffic issues and rejuvenate the public spaces.
