The non-monolithic surface of precast concrete pavers allows them to minimize the impact on the local environment. Where a paved surface is necessary, the segmental pavers can be integrated with the functions of the earth and environmental conditions thereby reducing the overall impact that a monolithic surface might impose.

This short video discusses current stormwater management practices and shows how PICP can be used as part of an effective sustainable, low impact development response to today's precipitation and stormwater management problem.

When compared to runoff from an adjoining asphalt lot, permeable pavement exfiltrate contains significantly lower concentrations of phosphorous and zinc, as well as reductions in total nitrogen, and thus provides for better water quality. To further test various permeable pavement designs, a parking lot consisting of four different types of permeable pavements and standard asphalt was constructed in Kinston, NC. The attached PDF evaluates this case study and the water quality improvement as a result of PICP.

Nashville, Tennessee is encouraging permeable pavement though municipal water laws.

Stormwater runoff quality and quantity from asphalt, paver, and crushed stone driveways in Connecticut. This study compared the quality and quantity of stormwater runoff from replicated asphalt, permeable paver, and crushed-stone driveways. 

The following case studies were compiled as part of the Denver Avenue Streetscape Design Project in order to help inform the design process for Denver Avenue’s streetscape.

Permeable pavements of concrete paving-stones for rainwater infiltration are established as a sustainable method for the drainage of traffic areas and for pollutant source control. Various systems for different applications exist. Pollutants like heavy metals and hydrocarbons in the runoff can endanger soil and groundwater, when the they are not sufficiently removed during infiltration.
