The Basic Idea For every great solution there must be a problem. Here is ours:

Before urban development there were landscapes and native plants that cleaned and controlled stormwater. Rainfall traveled through soil, over rocks and into channels before returning to the network of drainage basins—rivers, lakes, and wetlands--or our local Watersheds. This natural process was very important to water quality and the viability of the plants, people and wildlife depending on it. 


With urbanization came impervious surfaces—

rooftops, asphalt parking lots, concrete sidewalks, pipes, culverts, etc. These manufactured landscape features dramatically alter the hydrology of a region resulting in a series of negative consequences: poor water quality in watersheds and groundwater, flash flooding, erosion, destruction of aquatic habitats, and overwhelmed water treatment facilities.


Stormwater management is a very significant problem.


The Permeable Solution Permeable Interlocking Concrete Pavement (PICP) is a sustainable paving system engineered to help manage stormwater runoff and improve water quality. When stormwater falls on PICP , the water travels from the surface of the pavers into the stone filled gaps in between, then through layers of progressively larger pervious stone which acts as a filter for environmental toxins similar to the natural system detailed above or native plants in a rain garden. The paver base then acts as a miniature, natural onsite water treatment plant, cleaning water as it finds its way into the subsoil below.  because the storage potential of PICP is so substantial, rainfall from rooftops and other nearby hardcover surfaces can be incorporated into PICP for additional environmental gain, and as a means to resolving damaging drainage issues.


The Facts

Permeable Interlocking Concrete Pavement (PICP):

  • Creates a 100% pervious surface

  • Infiltrates 100-300 inches of Stormwater per hour

  • holds 5x its own surface area of additional runoff

  • Decreases the local flood potential

  • Filters out environmental toxins

  • Processes vehicular pollutants

  • Eliminates the need for detention and retention ponds

  • Connects to rain gardens and other sustainable building solutions


Properly Installed PICP:

  • is recognized as a Best Management Practice (BMP)

  • Supports Low Impact Development (LID) principles

  • Meets U.S. Environmental Agency (EPA) performance criteria for BMP

  • Awards LEED and Green Globe points

  • Allows for local and National Watershed (CWP) Tax Credits

  • Provides compliance with U.S. National Pollutant Discharge Elimination System (NPDES) regulations
