Environmentally Friendly Permeable Paving: New paving reduces pollution
If you're planning to build or replace a driveway or other paved
area, consider a permeable surface before you invest in concrete or
asphalt. Available in a myriad of colors, shapes and patterns,
permeable pavers can make your property look better and have a
significant positive impact on the environment.
In response to the growing environmental stress of land
development which diminishes the natural water filtration provided
by soil - storm water run-off is often mixed with motor oil,
fertilizers and other substances - paver manufacturers have
developed permeable systems that help address this source of
pollution for our lakes, rivers, coastlines and groundwater.
By allowing rainwater and snowmelt to drain into the ground,
rather than sending it off into our streets and storm drains,
permeable paving helps reduce runoff while filtering pollutants
from the water. It can even lower the temperature around a house in
the summertime as it absorbs moisture instead of heat.
With every 30-by-30 foot patch of concrete or asphalt shedding as
much as 550 gallons of water in a one-inch rain, permeable paving
is an excellent alternative to traditional methods and an ideal
solution for driveways, parking areas, sidewalks, pathways and
Just as rain soaks into the earth in forests and fields, permeable
paving allows the water to percolate into the sub-soil the very
Using a selection of paver blocks and grids, water is permitted to
pass through the permeable surface, and then through a system of
various sized gravels, back into the soil. Some installations also
support grass or other suitable vegetation, providing a naturalized
A growing number of commercial installations across the country
demonstrate how permeable paving can reduce the quantity of surface
runoff, particularly for small to moderate-sized storms, as well as
the flow of runoff pollutants.
Functional, durable and aesthetically pleasing, permeable paving
is proving especially effective in areas near Lake Michigan where
the soil is particularly sandy. Because it can virtually eliminate
runoff, permeable paving has the potential to reduce the need for
retention ponds and/or underground sewer pipes.
