US is not prepared for a major oil spill in the Arctic region.

The Alaska Outer Continental Shelf is estimated to contain over 30% of the domestic off-shore oil reserve in the US. Oil production industry in northern Alaska has grown rapidly since 1960s and continues to expand today. With decreas-ing on-land production during the last decade, oil companies have started drilling in the Arctic Ocean to fulfi ll the country’s demand for oil. A major oil spill is inevitable with intensive oil drilling, yet the region does not have the appropriate infra-structure to react.

This project attempts to design for the future development of off-shore oil production activities in the area of Stefasson Sound in the Beaufort Sea. The key goals of the project are to use landscape strategies to minimize the risk of oil spilling in the arctic ocean, protecting the rare kelp community within the area and to develop a sustainable oil production hub that can accommodate different needs and adapt to future changes.

On April 20, 2010 in the Macondo Prospect oil fi eld near the Loui-siana coast, a deepwater drilling rig explosion started a massive oil spill in the Gulf of Mexico region. The leak was not stopped until 3 month after the explosion and it is estimated that 185 million gal-lons of crude oil was released in the gulf region. . It is the largest accidental marine oil spill in the history of the petroleum industry and is also considered to be the largest environmental disaster in U.S. history.

In 2008, Shell Oil acquired the right to drill offshore by winning the a lease of 2.75 million acres in the Chukchi Sea and is planning to start exploration drilling by July, 2010. Yet, because of the incident of Deepwater Horizon spillage, the project was put on hold until the government sees a promising plan to deal with inevitable oil spill occur in region.

background

s i te and ecology

Stefansson Sound is one typical coastal lagoon located in the central Beaufort Sea area of north Alaska, which has the larg-est oil reserve in the Arctic. Offshore drilling activities have been growing rapidly for the past few decades.

On the route for busy ship traffi c, Stefansson Sound has the potential for community development and becoming a new centre in Central Beaufort Sea region..

The ecologies in the area is especially rich because of the unique hard rock substrated rafted to the area by early ice movement. The rock bed has become a signifi cant habitat for a kelp community as well as a lot of other associated arctic species. Stefansson Sound has been designated as the most environmental sensitive area by the State of Alaska.

The major strategy proposed is to construct a series of islands function as the base station for immediate response to oil spill. At the same time, these constructed islands are also used for building community and protecting local ecology.Based on the site analysis, the islands are oriented and confi gured to served for the different objectives.The islands are built with gravel, which comes from the gravel mines in the coastal area nearby. The gravels are trucked to the construction site and build the landform.

On each island there are three components: spill response, community and ecology. The three components are not separated from each other but coexist on each island to serve for the three objec-tives. The dimension of each island is determined by the space needed for each component.

This Project imagines the Seaton site which is located in Pickering, Ontario within the Greater Toronto Area (GTA) transforms into a recycling hub to reduce the environmental footprint resulting from urban growth of the region, but also becomes the testing ground to see how waste can replace some of the non-renewable resources that we common-ly use to build community, turning waste into environmental friendly construction materials.

The proposal not only helps to reduce the amount of C&D waste and agricultural waste in the region, most of which is not currently being recycled, turning them into useful material; it also promotes a more sustain-able way of construction and community building.

The site is divided into 4 major zones: agricultural zone, industrial zone, urban research centre zone and residential community zone. The major strategy is to provide a network of service corridor across the different zones where waste is collected, transferred, recycled and transformed.

This project explores the opportunity of using the vast under-developed space of the City Park as a temporary storage space for the excess water generated by storm events and helps to mitigate the fl ooding risk in the surrounding area.

The major strategy is to create a new channel in the City Park and redirect the fl ow of water into the park for temporary storage. The land of the City Park is re-sculpted with changing topography to have water storage areas of different sizes and capacity. The fl oodwall system is also replaced by berm structure to provide more stable protection to adjacent neighbourhood.

Currently, stormwater in New Orleans’ drainage basin 2 and drainage basin 7, with a total area of 4300 acres, both drain through the thin Orleans Canal, with a total open water surface of 66 acres, while the City Park, with a total area of 1300 acres being completely underdeveloped.with very little program and use in the park. The Orleans Canal uses the levi wall system for fl ood prevention, which is not reliable at all.

The montage assumes what is potentially happening when a 100 year flood occures. The neighborhood area is very vulnerable to flood risk because flood wall is not strong enough to handle with such high pressures from wind and surge at a major Hurricane level.

Once the drainage canal is diverted into City Park, and additionally with a berm protective structure installed, the neighborhood is no longer a floodplain

The site is a private residence located in Guangzhou, China with large terrace area attached to the living area. The design uses the simple modern geometrical language of retangles to create different planters to accommodate various native plant species. The different confi gurations of the planters in combination with the planting function as visual barriers to protect owner’s privacy as well as providing a interesting space for the family spend time together.

The project is based on one chosen verb, in this case, the verb of interest is “pixelate”. A template is then created based on the verb with punched holes at the bottom. Different amount of sand is then poured over the template to generate different sand form. From the sand form, a stick model is developed to further represent the spa-cial quality derived from the verb.
