Expert Response
Thank you for reaching out — you’re definitely not alone in dealing with this issue, and it’s great that you’re thinking about transitioning to a permeable system.
Given your description, it sounds like your driveway is currently acting as a direct conveyance, concentrating runoff toward your house rather than allowing it to infiltrate.
A well-designed permeable driveway can make a significant difference, but the key is matching the system to your site conditions. In our region (central Maryland / Chesapeake Bay watershed), the most common permeable driveway options include:
Permeable pavers (interlocking concrete or stone)
Pervious concrete
Porous asphalt
Each has pros and cons depending on the factors listed below, and they are all typically very expensive to implement.
Factors to consider: Soil type and infiltration capacity
Slope (very important in your case, given the flow toward buildings)
Drainage area (how much water is coming onto the driveway)
Maintenance expectations
For situations where water is currently flowing toward the house, I often recommend pairing a permeable surface with additional drainage strategies (see our website for more information https://extension.umd.edu/programs/environment-natural-resources/program-areas/watershed-protection-and-restoration)
If you move forward with permeable pavers, I strongly recommend working with a contractor certified by the Concrete Masonry and Hardscape Association https://www.cmha.org/, as proper design and installation is critical to long-term performance.
You can also search for trained professionals through the Chesapeake Bay Landscape Professional (CBLP) database, which includes contractors familiar with stormwater practices in our region. https://cblpro.org/
Please reach out should you need anything else.
Thanks!
