Topography, or the shape of the land, plays a big role in how campuses are designed. It helps decide where buildings, pathways, and open areas should go.
Key Factors of Topography in Campus Design:
-
Site Layout:
- Changes in elevation can make the landscape look interesting. This allows for buildings and paths that are on different levels, which can create enjoyable experiences.
- A study by the American Society of Landscape Architects found that when the land rises by 10%, the views can get better by 20%. This makes the area more visually appealing.
-
Water Drainage:
- Studying the shape of the land helps manage rainwater better. Well-planned campuses can reduce about 70% of rainwater runoff, which means less chance of flooding.
- Areas that are steeper than 15% need special design techniques to stop soil from washing away.
-
Microclimates:
- Different heights on the land can create unique microclimates. These differences affect what plants can grow and how outdoor activities are planned. For example, places that get sunlight from the south can be 5°F warmer, making them better for outdoor fun.
-
Accessibility:
- The U.S. Access Board suggests paths should have a slope ratio of 1:20 to be easier for everyone to use. It’s important to carefully plan around the topography to make sure paths are accessible while making the campus flow nicely.
Soil Interaction:
- The way the shape of the land and soil types work together is important. Sandy soils, which are found in 15% of U.S. soils, let water drain quickly, while clay soils, found in 25%, hold onto water longer. This affects landscaping choices.
- About 30% of campuses use soil studies to help decide what plants to grow and how to build structures. This helps make sure that the designs are sustainable and last a long time.
By looking closely at the land's layout, architects can create university spaces that are functional, strong, and enjoyable, all while fitting in nicely with nature.
