Airport Site Selection site selection Three principals to choose the site for the airport: 1. the site should be as flat as possible 2. demolition to natural resources should be as less as possible 3. avoid negative effect to the residential area and avoid occupying the place of houses/ roads. Site 1 is on the highest elevation of the ground. It won’t occupy the exist site of roads or houses, but it do bring negative effect to the neighborhood. Most of the people will have to move out because of the noise. Site 2 will not bring such huge negative effect to the whole residential area although it does effect some of them, but it occupies a main road. Site 3 occupies a road as well. But the site is flatter than the first two, and it’s comparatively far from the houses.

Introduction: Bioswales System as Green Infrastructure

Green infrastructure is a network of natural system for solving urban and climatic challenges. It is a concept originating in the mid-1990s that highlights the importance of the natural environment in decisions about landuse planning. Bioswales system is aimed at stormwater management as a kind of green infrastructure. Today, many cities are facing severe water uncertainties, such as floods, droughts and upstream activities on trans-boundary rivers. The increasing pressure, intensity and speed of urbanisation has led to the disappearance of any visible form of water infrastructure in most cities. Green Infrastructure controls stormwater by using it as a resource rather than a waste. Water is either directed to engineered systems for infiltration or detained at a slower rate before it enters the combined sewer system.

STEP 1: Collecting Nature & Human Society Data of Utah

South Jordan

Annual Precipitation of Cities in Utah

Nature Analysis soil types & ground water contaimination

Layers describing data in Utah made by ArcScene

Human Society Analysis schools & libraries

Utah is the 13th largest state in the United States. The Salt Lake City is the capital of the state. The site of the project, South Jordan, locates in the Salt Lake Valley between the 9,000-foot (2,700 m) peaks of the Oquirrh Mountains and the 12,000-foot (3,700 m) peaks of the Wasatch Mountains. The state is known for its natural diversity. The primary source of precipitation for the state is the Pacific Ocean, with the state usually lying in the path of large Pacific storms from October to May. In summer, the state, especially southern and eastern Utah, lies in the path of monsoon moisture from the Gulf of California. Salt Lake City sees about 60 inches (152 cm) of precipitation a year.

Loam was the most common soil texture for water retrofits considering the imperviousness of the soil. In order to avoid re-contaiminate the water, the ground water should be clean enough. The potential blocks should be near watershed area for the purpose of drainage.

Dissolve the soil type. Choose the parcel with soil type of “loam” and located with intersection of watershed. intersected “loam” with watershed

intersected soil with watershed 500m buffer

I need the parcel to be within the 500 meter buffer of the watershed, so that it could be convenient to transfer the sewage (rain water collected).

Select the blocks which are within 100 meters of the selected soil place. Soil with perfect imperviousness are selected to deal with the sewage. Blocks within 100 meter to the sitescould be used to collect rainwater. It’s cheaper and more effective. Function used: Dissolve, Select By Location, Select By Attributes, Buffer Wizard

Result: Potential Roof Gardens

THIRD STEP Final Result

GIS Analysis

Qingyuan locates on the north of Pearl River Delta, in the middle of North River. The natural environment of this city is in a good condition, with mountains and water system. The water area of the whole city is about 107.34km 2 in different forms such as lakes, rivers, streams and reservoirs. Mountains are here and there. But the natural resources of the city is scattered without organization. And the protection of the natural resources is very much in need since a city is going to be developed here. The greenway could help preserve the ecological corridors in the development of the city and deal with the problems such as storm-water management. It could also offer a sustainable alternative transportation by offering access to different components of the city.

RESEARCH ON TRANSPORTATION NECESSITY

The greenways for transportation necessity should offer convenience for residents especially commuters. The purpose should be realized by offering non-motorized access to public transfers and other public or transportation facilities.

It's common for multi-functional greenways to have pocket parks on the side. Use the sunlight angle to decide the width and the location of the pocket parks and pay attention to the street view at the same time.

PERSPECTIVE1 multi-functional (transportation & recreation) greenway

Put the promenade in the middle of the road to reinforce the visual axis and strengthen the vista. Stormwater management garden could be integrated with the promenade. Tree canopy enhances urban ecology, the streetscape is emphasized.

PERSPECTIVE2 transportation greenway

Cycle lane and promenade are comparatively wider for transportation necessities. Establish an economically vibrant and engaging streets that includes pedestrian amenities and comfortable gathering space for friends and family.

PERSPECTIVE3 ecological greenway

The ecological greenways are established to ensure that the ecological corridors in the urban area will not be threatened because of the development of the city. They link habitats and protect wildlife movement.
