Water runoff is reduced by as much as 100%. The system delivers maximum strength to handle both pedestrian and heavy vehicular traffic while providing remarkable curb appeal, convenient access to underground utilities and outstanding economic results on a 30-year life cycle cost analysis. In addition, eliminating retention ponds enhances land planning. Holland Permeable XL is therefore, an economically smart choice for driveways, parking lots and roads.
This stormwater management system is designed to trap first-flush pollutants and reduce impervious areas. Pavingstones are laid out in a variety of patterns with gravel between them. The system is built on an open graded series of stone bases, which offer infiltration and partial treatment of stormwater pollutants. This system has been approved by the Federal EPA as a post-structural BMP (Best Management Practices) for compliance with NPDES Phase II rule.
Below the pavers typically sits a 12-inch to 24-inch sub-base of 2 1/2-inch to 3-inch fractured rock, a 4-inch deep base of 1/2-inch to 1-inch of clean gravel, and a bedding of 1/4-inch to 3/8-inch stone. Refer to the Bio-Aquifer Storm System diagram (shown).
