What is porous pavement? It is a pervious surface designed and created to replace traditional paved areas we find utilized through-out the construction industry today. There are many possibilities available to eliminate impervious surfaces such as permeable concrete, porous asphalt, paving stones or bricks, grass pavers, and other permeable surfaces designed to replace traditional pavement.
Green Stormwater Infrastructure practices are increasing in use, particularly in Florida. In January of 2019, Congress enacted the Water Infrastructure Improvement Act, which defines green infrastructure as “the range of measures that use plant or soil systems, permeable pavement or other permeable surfaces or substrates, stormwater harvest and reuse, or landscaping to store, infiltrate, or evapotranspiration of stormwater and reduce flows to sewer systems or to surface waters.”
Permeable pavement systems and usage is considered a green Stormwater Infrastructure practice. Some of the primary usages for porous pavement are for walkways, patios, plazas, driveways, parking areas. It is also an excellent alternative for lower volume pedestrian areas, vehicle low speed situations such as parking areas, residential driveways, urban area bike paths.
Green infrastructure can also be considered a stormwater management practice that may include such methods as green roofs, trees, rain gardens that can capture and infiltrate rain where it falls.
When construction projects that incorporate such practices in their design and planning can produce multiple environmental benefits. One in particular is eliminating the potential for polluted stormwater runoff. Green infrastructure practices can provide flexibility to contractors and developers that may be faced with the need to adapt infrastructure to a changing landscape.
