Key considerations are for ensuring pervious surfaces have sufficient infiltration and storage capacityinclude:
An important consideration with pervious surfaces is that soil, sand and
other site materials should be prevented from contaminating the pervious surface
during construction, thus reducing its free-draining nature. Most clogging of pervious surfaces (particularly porous asphalt) occurs
during construction. This can be overcome by educating contractors and workers
and explaining how the pervious surface works and the importance of keeping
it clean. Construction traffic should be prevented from tracking mud and soil
into the pervious surface and proper supervision and inspection of the installation
should be budgeted into all projects.
After actual construction works cease the preparation of landscaping should
be carefully designed and managed to prevent carelessly deposited top soil,
turf and other materials blocking the pervious surface. Runoff from landscaped
areas, which is a sources of soil and debris, should be prevented from flowing
onto the pervious surface and causing clogging. For further information on maintenance click here.
