During heavy rainstorms and continued rains over several days, storm water run-off creates all sorts of problems and becomes a major concern to homeowners and businesses. To help alleviate these problems, cities all over Marin and Sonoma counties are recommending, and in some cases requiring, the installation of permeable pavers.

Unlike impervious surfaces such as concrete and asphalt, permeable pavers allow water to seep into the ground, which helps prevent flooding, and as an added bonus, are a far better solution for the environment.

How It Works
With impervious materials, water runs over the surface and into storm drains or collects in large puddles, causing standing water, flooding and a host of other problems. Because permeable pavers have larger spacers than standard pavers, the joint between each paver is wider, so, instead of running over the surface, or collecting in low spots, water filters down between the pavers through a fill of small stones. The permeable base beneath the pavers allows water from the surface to percolate down into the ground or drainage system.

Before beginning a permeable paver project, it should be determined what will be done with the water. In many cases it is most beneficial to let the water settle back into the ground below. In other cases, it may be best to set up a drainage system in the base to capture and salvage the water. A qualified installer can help determine the best process for your project.
