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 Humberwood Community Centre has permeable pavement parking spaces constructed in 1995.   The pavement condition is good, with some slumping though it is still suitable to regular parking.
