Replace an impermeable walkway or driveway with permeable pavers or other surfaces
Why This is Green
When surfaces—of driveways, walkways, patios—are impermeable, water cannot seep through them and down into the ground. So they create runoff. Storm water runoff from streets can pollute our waterways; just think of all of the hazardous crud that’s on any given driveway. When water is absorbed by the ground, the earth acts as a filter for most but not all of these pollutants. From there, filtered water makes its way into underground aquifers, replenishing them.
To reduce excessive runoff and pollution, install permeable surfaces like grass, gravel, and plants (which also help improve air quality). You’ll be in good company; the city of Chicago is replacing nearly 2000 miles of alleyways in the city with permeable paving. This should also help reduce the heat that asphalt surfaces create. Urbanites who have survived a summer in the city know how useful that would be in terms of comfort not to mention the reduced air conditioning bills and carbon emissions.
Permeable pavement isn’t overly expensive if you’re building new or replacing something old. That said if you can’t rip up your preexisting driveway, you can install gravel trenches on the side. These are less expensive and will catch some runoff.

How To
Look into the right permeable surface for your surroundings and specific soil. Install them properly and treat them according to manufacturer suggestions during the winter (some cannot have sand or salt on them, for example, as this will block proper drainage).
If you need help installing, seek out a professional.
