Project Description:  The CleanTech Corridor is a 4 mile long district on the eastern edge of Downtown Los Angeles, stretching from the Los Angeles State Historic Park in the north, to the CleanTech Manufacturing Center in the South, and includes both the east and west banks of the channelized Los Angeles River.

The 2,000-acre development zone which encompasses a mix of industrial areas along the Los Angeles River was recently designated as the “Los Angeles Cleantech district”: the cornerstone of the Mayor’s vision to put Los Angeles at the forefront of the clean tech revolution and to transform the old, downtown industrial core of Los Angeles into an incubator for green jobs, technology and the growth of LA’s economy. The Clean Tech Corridor is envisioned to bring together researchers, designers and manufacturers dedicated to the development of clean technology products and solutions to climate change challenges.

To imagine the Cleantech district, the team answered an open ideas competition organized by SCI-Arc’s Future Initiatives program, the Mayors’ office and The Architect’s Newspaper.

To move beyond industrial use and create an integrated economic, residential, clean energy, and cultural engine for the city, the team, led by ML+A, explored high performance infrastructures and innovative landscape strategies to develop a highly contextual strategy based on re-using existing and under-utilized resources on the site. The team targeted three major urban infrastructural resources for reuse: the historic bridges crossing the Los Angeles River, the industrial urban fabric, and the LA River itself.

Hypothesis

The urban character of the Los Angeles industrial corridor is a paradoxical blend of functionality and disregard. Currently most of the cities distribution, shipping and freight storage occur within this zone. However, there is no structural logic or organization to this corridor. Freight modal hubs are littered along Alameda and Olympic. This blanket of industry is now a barrier between the Eastern Los Angeles community and downtown cutting off a large residential community from accessing the economic center of the city. Due to the lack of organizational clarity to these transit systems, 20-30 percent of the ‘industrial’ buildings that populate the site are outdated with no inherent flexibility or market value – currently shuttered, and left derelict. Conversely, this is part of what makes the clean-tech corridor site so provocative – its raw space and potential for industry and innovation. However, to function within a modern metropolis, the corridor needs a systemic overhaul, a retrofitting to transition into an intermodal landscape in which systems for energy creation (including solar arrays and hydroelectric power), waste management, transportation, and water runoff are integrated.

Solutions

1. The Bridges as destinations
The team chose to perceive the heroic and monumental bridges along the river as untapped opportunities for dynamic, flexible public space. Largely overlooked, the series of concrete bridges traversing the LA River are a major urban element that imposes a unique identity to the corridor. Major pieces of urban infrastructure, the bridges are an iconic remnant of a once useful and coherent transit system, before the freeways and cars, when the Los Angeles population moved in a less nodal, disparate fashion. The architectural bridges are programmed to integrate the community east of Los Angeles into the site, and formally stitch the two sides of the river.

2. The re-use of existing industrial fabric
The “high performance ruin” is one such strategy of remediating the current vacancy of the site and propagating the development of an interior small business corridor. By editing elements of existing building stock down to elemental form (and retaining a connection to the utility grid) new uses can be integrated with minimal investment. Ideally, the urban ruin is a flexible building platform allowing for different uses to be installed facilitating an adaptive, urban flexibility responsive to shifting business models and volatile markets.

3. The recalibrated LA river
The clean-tech corridor has a symbiotic relationship with the river channel and the periodic events of storm water. The district is re-envisioned as a water filter and percolation zone, while the river itself is redefined as a waterway to support ecological services and social recreation. Also addressing the current inadequate preparation for a 100 year event flood, flood pockets and open space have been introduced along the river as flood control devices to relieve the river in periods of excessive storm events.

Additional Information: Sponsored by SCI-Arc and The Architects Newspaper, 70 entries were received from architectural firms and students in 11 countries. The competition asked architects, landscape architects, designers, engineers, urban planners, students, and environmental professionals to create an innovative urban vision for the CleanTech Corridor. Entrants were encouraged to challenge conventional wisdom and move beyond industrial uses—creating an integrated economic, residential, clean energy, and cultural engine to re-invigorate the industrial district into a thriving mixed-use center. This design is a winning submission.

Project Description: Currently under construction, Brooklyn Bridge Park will eventually encompass approximately eighty-five acres and 1.3 miles of waterfront. The park’s goals are both ambitious and straightforward: to preserve the dramatic experience and monumental character of the industrial waterfront while reintroducing self-sustaining ecosystems to the site and investing it with new social and recreational possibilities.

MVVA took a broad mandate of sustainability and applied it across a range of spheres—ecological, structural, cultural, and economic. Sociological diversity, programmatic flexibility, and a robust post-industrial nature are threaded together to create a park that can function both as a metropolitan park on the scale of Olmsted’s landscape infrastructures and as a collection of smaller, nested neighborhood parks.

Brooklyn Bridge Park’s design took on a site with limited access points, a narrow overall width, extreme noise pollution from the adjacent elevated highway, a complex structural waterline condition, and a goal of capturing and recycling stormwater. Excess stormwater is collected from buildings, paved areas, lawns, and planting areas, conveyed into underground tanks, and then cycled and cleansed through rain gardens, supporting a lush swath of rain garden plantings. This runoff collection system, in conjunction with the increased use of water-absorbing lawn and planted areas, dramatically curtails the discharge of stormwater runoff into city systems and lowers the likelihood of combined sewer overflow.

Pier One and Pier Six function as “urban junctions,” entrances to the park that will attract families and individuals on a daily and year-round basis with programs such as playgrounds, picnic tables, benches, areas of accessible natural plantings, a dog run with water, and park concession buildings with restrooms. This first phase of Brooklyn Bridge Park provides vital new social spaces and urban programs while bookending the site and laying the foundation for a continuous waterfront park to grow in between. The salt marsh landscape on Pier 6, sports fields and courts on Piers 2 and 5, a community lawn space on Pier 3, a beach, and other park amenities will come with future phases of park construction.


Longzi Lake Master Plan and West Bridge Park

Project Title: Longzi Lake Master Plan and West Bridge Park

Project Description: Bengbu City lies in the northern Anhui Province, China. In the western part of the city, the government has begun to implement an extensive development plan for new residential, commercial, and tertiary education facilities arrayed around the Longzi Lake Scenic Area. Recognizing the enormous potential value of an attractive lakefront image for the city, the State Land and Planning Bureau for the New Town Comprehensive Development Zone of Bengbu commissioned AECOM Design + Planning (EDAW) to help articulate this vision into a comprehensive master plan for the entire 3890 hectare Longzi Lake Scenic Area.

Following completion of the master plan, AECOM also completed the design for the West Bridge Park. The West Bridge Park occupies a strategic focus point on the western shore of Longzi Lake. The task was to create a signature lakeside park that captures the culture, history, and future vision for Bengbu as an aesthetically, environmentally, culturally, and economically prosperous lakefront city. The design also creates an active urban waterfront park that encourages interaction among people, and between people and nature. The success of this park will provide a benchmark for the future phases of Longzi Lake and adjacent urban areas. The programs consist of a revitalized beach, floral gardens, urban amphitheatres, and multipurpose lawns.

The design concept emphasized features that give Bengbu and Longzi Lake a clear and distinct identity. Important components include: minimizing earth-works to preserve the original land form; utilizing a low-impact design to reduce and filter the stormwater runoff entering Longzi Lake; selecting locally appropriate species that fit the climate and soils of Bengbu, as well as providing habitat for birds, fish, and insects; reducing irrigation and maintenance costs; and drawing on local traditional methods for the structural design.
