	Evaporation of water at or below the surface also produces surface cooling, as opposed to the traditional heating of paved areas. This is especially beneficial in cities which experience extremely high temperatures in summer – traditional “blacktop” temperatures can make some public spaces unusable in warmer weather.

Permeable pavements offer many benefits, both aesthetic and practical. Some of the benefits are listed below:

* Reduces storm water runoff, including reduction of temperature, total water volume, and flow rate.
* Treats water runoff.
* Increases groundwater infiltration and recharge.
* Provides local flood control.

Some of the disadvantages associated with these pavements are listed below:

* Highly contaminated runoff can be generated by some land uses where pollutant concentrations exceed those typically found in storm water.
* Heavy traffic loads can cause severe distresses which leads to pavement failure.
* In cold climates, salts used for removal of snow, contains chlorides that could migrate through the porous pavement into groundwater.
