Humber College, Soil quality below permeable pavers – documented in the Permeable Pavement and Bioretention study

As part of a 3 year study evaluating the effectiveness of permeable pavement and bio-swales under southern Ontario climate conditions a number of older bioretention areas were surveyed to assess the effect that age may have on various aspects of the infiltration practice.  Soil quality was assessed to determine the extent to which road runoff contaminants build up in soils over time.

The Humber College permeable parking area is located at the entrance to the Humber Arboretum on campus.  The pavers were installed in 2003 though they may not have been designed to be permeable. The ratio of surface voids to pavement was less than at the other sites surveyed.
