What if your driveway were beautiful? If you have a typical American stretch of asphalt for a driveway, this question might come off as an absurd provocation, but Andrea Hurd, the founder of Mariposa Gardening & Design, has proven over and over that a beautiful place to park your car is possible. Her Bay Area firm uses their expertise in stonework and horticulture to create driveways that are an attractive addition to the landscape. Hurd’s interest in reimagining driveways doesn’t stem solely from aesthetic ambitions, though.
Trained in permaculture, Hurd worked with the San Francisco League of Urban Gardeners in the 1990s. There, she learned that the water that runs over your driveway picks up oil and gas that has leaked from cars. “That polluted water goes into storm drains that go straight to the Bay,” says Hurd. One solution to manage this problem is to replace conventional driveways with permeable ones, which allow stormwater to be filtered through the soil, keeping pollutants out of natural bodies of water.
The benefits of a permeable driveway don’t end there. By keeping rainwater on a homeowner’s property, the water soaks into the ground to recharge the groundwater table. Ripping out concrete can also reduce the heat island effect, as concrete reflects the sun’s heat. And if you add plants to your new permeable driveway, you can create habitat for pollinators—not to mention improved curb appeal. Perhaps best of all? Your newly beautified driveway can be used as garden space when your car is not parked there.
Here’s what you need to know to create your own beautiful, permeable parking spot:

Remove the concrete.
The first step to creating a permeable driveway is to remove non-permeable concrete or asphalt surfaces. Unless you’re handy with a jackhammer, this is probably a job for a pro. “Hopefully you have a driveway that was built to code, which means you’ve got a sufficient amount of base material underneath the concrete pour,” says Hurd. But if that is not the case, your contractors will need to regrade the driveway so that water slopes away from the foundation of the house.
