Sustainability - How Can Porous Pavement Help you Build a More Sustainable Parking Lot?

June, 27, 2020 By CASSIDY PAVING 3 min read
Are you interested in green and sustainable ways of living? Cassidy Paving would love to share the great benefits of porous pavement on the environment as compared to traditional ways of asphalt paving. Together we can design a parking lot that is functional, beautiful, and sustainable for years to come. Here’s more about the benefits of porous pavements.

What Is Porous Pavement?

The U.S. Geological Survey defines porous pavement as “a porous urban surface composed of open-pore pavers, concrete, or asphalt with an underlying stone reservoir.” Just like any porous surface, water has more room to drain because it can get through the surface itself safely and into the soil subsurface. If there are any toxins in the water they will be filtered through the stone base and released naturally into the soil. Cassidy Paving always recommends the most sustainable options for asphalt paving for customers. READ MORE: Four Things to Consider When Selecting a Parking Lot Location

Benefits of Porous Pavement

The Massachusetts Stormwater Handbook is a great resource for maintaining sustainable clean water and they have listed various benefits of porous pavement including:
  • Reduced stormwater runoff volume from paved surfaces
  • Reduced peak discharge rates
  • Increased recharge through infiltration
  • Reduced pollutant transport through direct infiltration
  • Can last for decades in cold climates if properly designed, installed, and maintained
  • Improved site landscaping benefits (grass pavers only)
  • Can be used as a retrofit when parking lots are replaced
Even if your first priority isn’t being sustainable, a porous parking lot can help you avoid standing water. Standing water or drainage malfunctions are often causes of asphalt pavement deterioration in the form of potholes, cracks, and raveling. Porous pavement can last up to 20 years without any potholes or cracks and can withstand heavy loads and steady traffic.


If your budget is a large concern for your parking lot project, we can help you crunch the numbers. Porous pavement costs, on average, $2 to $3.50 per square foot while regular asphalt can cost as low as $1 per square foot all the way up to $5. While the initial investment of porous pavement may seem a little more, the money that you will save on maintenance will give you a large return on investment. You can get away with little to no fixes on your porous pavement parking lot for at least 20 years. Looking at the overall costs year over year this option can give you the most for your money while helping with its footprint on the environment.
