After a look into bioremediation (cleaning up of the soil and the site using natural elements such as plants)  and the functions it serves, I decided to take a pass at representing how some of these techniques could be used on the site. Small sectional details show the implication of the additional "layer" on the site being used as a filter to clean runoff water. Also shown is a conceptual plan to show how these spaces may influence and integrate into the existing site. 

In this study I focused on one small area of the site, shown in the upper corners of the drawing. But the idea is that some of these techniques may be used throughout the site in various ways.
