As commercial developments grow and cities densify, the need for effective stormwater management is more critical than ever. One sustainable solution that’s gaining momentum is permeable asphalt pavement. Designed to let water pass through the surface, this innovative material supports drainage, reduces runoff, and contributes to environmental goals.
In this guide, we’ll break down what permeable asphalt is, where it works best, and how it supports sustainable commercial construction.
What Is Permeable Asphalt?
Permeable asphalt, also known as porous asphalt, is an engineered pavement system that allows water to flow through the surface into an underlying aggregate reservoir, where it slowly infiltrates into the soil.
Unlike traditional asphalt, which is impervious and directs water toward storm drains, permeable asphalt manages runoff at the source, reducing flood risk and improving water quality.
Benefits of Permeable Asphalt for Commercial Sites
1. Improved Stormwater Management
- Reduces surface runoff that can overwhelm drainage systems
- Controls flooding and ponding during heavy rain
- Naturally filters pollutants before they reach groundwater or local waterways
2. Supports Sustainability & LEED Certification
- Helps earn points in LEED and other green building systems
- Reduces the need for separate stormwater infrastructure
- Allows for green infrastructure credits in some municipalities
3. Reduces Urban Heat Island Effect
Because of its open-graded structure, permeable asphalt tends to remain cooler than dense-graded asphalt, especially when used with light-colored sealcoats or reflective aggregates.
4. Long-Term Cost Efficiency
- Can eliminate the need for curbs, gutters, and retention ponds
- Reduces maintenance costs related to stormwater control
- Offers long service life when properly maintained
Where Permeable Asphalt Works Best
While permeable asphalt is not suitable for every commercial environment, it excels in:
- Low-traffic areas like employee parking lots, walking paths, or overflow lots
- Corporate campuses and government properties are prioritizing sustainability
- HOA communities with stormwater mandates
- LEED-certified building projects
It is not ideal for heavy truck routes, industrial yards, or steep slopes where structural stability and drainage capacity must be more robust.

Common Questions About Permeable Asphalt
Is permeable asphalt durable enough for commercial use?
Yes—for low- to medium-traffic areas. With proper design and installation, it can last 20+ years with routine maintenance.
Does permeable asphalt clog?
It can if not maintained. Routine vacuum sweeping and inspection prevent clogging and preserve permeability.
Can it handle snow and ice?
Yes. Permeable asphalt drains meltwater, reducing refreezing and slippery conditions. Snow plowing is also safe when done carefully.
Does it require a different sub-base?
Yes. Permeable asphalt systems include a stone reservoir layer to hold and infiltrate stormwater effectively.
A Smart Move for Sustainable Drainage
Permeable asphalt is more than a specialty product—it’s a proven solution for managing stormwater while contributing to your sustainability goals. As environmental regulations tighten and LEED goals expand, commercial property owners should consider it where feasible.
