Group 1 – Oak Savanah
Plot 1 has the following characteristics:
Madison is a temperate climate, with an average of 30-40 inches of rainfall per year and an average of 40-50 inches of snowfall per year. This is a major factor in the design of Figure 1.
Edgewood College campus is one of the watersheds feeding directly into Lake Wingra. Direct surface runoff into the lake carries excess nutrient, soil sediments, and many pollutants into the lake before they can be filtered and cleaned. More information can be found about the conditions of Lake Wingra at http://lakewingra.org/. Most of these issues can be resolved by holding as much water in the soil as possible at higher elevation and allowing for filtration and cleaning of this water before it makes its way into the lake.
The parking lot requires plowing as does the access road running east to west at the southern border of our site. This access road appears to be used mainly by maintenance vehicles at this time.
This is a south-facing slope; the west end is shaded by Marshall Hall in the mid-late afternoon. It is a fairly sheltered area, the white pines and white oaks planted in the NE corner provide a windbreak. The centrally located rain-garden is bordered by large boulders that create a slightly warmer microclimate in their immediate area by holding and releasing heat.
The current landscaping now consists of lawn, requiring mowing, possibly fertilizer/broad-leaf herbicide, and spot re-seeding each year because of erosion. As mentioned previously, this area sheds water quickly and as is, does not slow down and hold much water within the soil. There are mature canopy trees (oaks, linden, ashes and mulberries) located mostly on the Northwest corner of the site that we would like to retain. Also at the Northeast corner, the young white oaks and white pines that are planted act as a windbreak for the majority of plot 1. Just south of the parking area is a rain garden that catches a lot of the run-off from the parking lot. This is full of many mature flower plants and grasses as well.
- Zones of Use
The upper access to Marshall Hall appears to be used primarily as an entry/exit only. There is a picnic table available but not many signs of localized activity. It is, however, in a nice location that would be ideal for developing into a patio, or seating area.
The current soil is a nice loam that washes easily downhill. Retaining this soil in the landscape will encourage healthier plants.
The most immediate need from an aesthetic point of view is the rock drainage culvert system currently sited in the middle of the southern edge of plot 1. By implementing the proposed design, the need for this drainage system should be eliminated. The mature trees provide high shade, the rain garden softens the edge of the pavement hard-scape and also provide for seasonal interest.
Group 2 was assigned the south facing slope of the eastern-most edge of the Edgewood Campus. The area is 65 feet wide and 270 feet deep with a steep slope dropping from an elevation of 932 feet above sea level to 908.
Group 3 – The Edgewood Gardens
To create a permaculture garden that reflects the following ethics: care of people, care of earth and the redistribution of resources. This garden provides foods to the various schools found on Edgewood College campus, and over time will contribute to the self-sufficiency of the campus.
