Replacing traditional impervious paving materials with porous pavements such as open-celled pavers is one method that site designers can use to negate the harmful environmental impacts of land development upon surface streams and waterbodies. Due to their porous nature, open-celled pavers can reduce the volume and rate of stormwater runoff when compared to impervious paving materials. Also, because they allow stormwater to infiltrate the soil, they have the capability of filtering pollutants from the stormwater runoff that would otherwise be discharged directly into surface streams. Unfortunately, many site design professionals are hesitant to utilize these pavers on site development projects due to a perceived lack of quality in the visual appearance of pavements composed of these pavers. Current research is underway at the University of Georgia to identify the brands of open-celled pavers and varieties of turfgrass that are best for use in this part of the United States.
