Example 1 The sloped topography and surficial geology of the site are characteristics favourable to infiltration devices such as channels, swales, buffers, and wetlands (shown here in Team Three’s concept for Surface Water Managment). Smaller swales running along local roads feed into the primary channeling system, represented by the thick lines running along the major north-south arterials.  Example 2  Team One considered streets and rear lanes as an organizing structure for surface water management. Water channels flow into larger north-south swales and provide irrigation for the central working greens (shown at the centre of the image at left).  These greens would serve a number of social, ecological, and recreational functions for the neighbourhood and would act as infiltration basins during storm events.
