Stormwater runoff from impervious surfaces like traditional streets, parking lots and sidewalks is a major contributor to flooding of adjacent low lying areas, in addition to surface water impairment and erosion along existing drainage courses. Permeable pavement is one of the solutions being utilized for both hydrologic and water quality improvement. Belgard’s Permeable Interlocking Concrete Pavement (PICP) system is fundamentally a large-scale detention reservoir with a drivable surface course. The open-graded base and subbase aggregates have approximately 32% and 40% open space respectively, providing for temporary water storage. Being the same aggregates used for railway tracks, they are more than capable of supporting vehicular loads. Use of PICP on various plaza and boulevard applications can add to the aesthetic look of a project, eliminate the need for traditional stormwater conveyance works, improve stormwater runoff quality and prevent downstream flooding and erosion.
