Best Location

A view of a driveway on King Charles Road that has grid style permeable pavement on top of it that allows rain to soak into the ground.

Permeable grid at a home on N. King Charles Road. This type of permeable surface is affordable and easy to install.

Permeable pavement works well on driveways and walkways that have:

Flat areas with less than a two percent slope
Two-foot drop in elevation for every 100 feet

Soil with a high infiltration rate
Allows water that is temporarily stored in the pavement to soak into the ground

Little tree cover
Tree roots or overhanging tree canopy can negatively impact the pavement

Small spaces
Many stormwater features require a large footprint

There are different types of permeable surfaces - like interlocking concrete pavers and plastic grid pavers. Talk with your contractor to see what's the best fit for your property.

Removing Pavement

Concrete driveways are not pervious. This causes rainwater to flow off the driveway rather than into the ground.

Why remove it?
Removing this pavement creates less stormwater runoff, which is better for our streams.


Offers a nice aesthetic 
Good for the environment 
Creates less stormwater runoff
Reduces water pollution

Permeable pavement spreads out stormwater, soaks it into the ground, and slows it down.
