Paving with Grass

It’s no secret that impervious surfaces add dramatically to stormwater runoff problems: erosion, downstream flooding, and pollution of surface waters. Paved areas are the biggest culprits. For most road surfaces, impervious asphalt and concrete pavement are the only practical options. But for parking areas, low-use driveways, utility access roads, pedestrian pathways, highway shoulders, and fire lanes, there are many advantages to surfaces that can absorb surface water instead of shedding it.
