Through their unique construction, permeable parking lots would decrease the amount of runoff and allow water to infiltrate the surface of the earth. For this research, three types of permeable parking surfaces were considered. Basically, this is just an area covered in bahia grass that is used for parking. A major incentive to construct vehicular turf is its low cost, relative to that of asphalt. It is a great deal cheaper, mostly because asphalt is more expensive to manufacture than it is to procure sod.
Building codes are more easily satisfied through the use of vehicular turf as well.
Also, vehicular turf is very natural looking, so the ambience is much more pleasant than with regular blacktop. It is constructed so that the concrete is poured leaving gaps in the pavement. These gaps are then filled with grass or aggregate to allow water infiltration. This type of parking lot construction, however, can prove to be more costly than asphalt. Most of the same rules that apply to vehicular turf apply to this type of parking lot as well.
