Example 6  
Section and plan of the Still Creek restoration. One way Still Creek has been restored is by changing the vertical and horizontal morphology of the stream course. Re-grading, riffles (or periodic changes in elevation), and meanders allow for the formation of pools and areas of calm water where fish and waterfowl can find habitat for feeding, resting, and laying eggs. The streamside vegetation (shown in section view) is vital to the stream’s health as it provides shade, organic nutrients and bank stability. 
Example 7 
Team One and Two approached ecological infrastructure differently in the valley bottom. As the drawing below shows, Team Two envisioned a bioengineering zone, at the centre of which is the Crystal Palace, a working greenhouse that uses solar aquatic technology to recycle the district’s sewage for methane gas and heat, which it then uses to grow hydroponic produce. Part of this energy would also be funnelled back up the slope for use in heating the district. Constructed wetlands surrounding the zone assist in the final stages of infiltrating runoff.

Example 8
This drawing  shows how Team One  integrated recreational amenity with stormwater management  and stream stewardship. Surface drainage patterns follow those of the grid structure and culminate in detention basins at street ends. These basins, together with playing fields (which double as large infiltration areas),  are organizing units around which the larger open-space structure takes shape.
