One of the strategies for controlling and reducing storm water runoff includes increasing the area of permeable surfaces such as vegetated roofs, porous pavement, and grid pavers. Grid pavers are:
  1. Ground cover foliage application 2-3 inches above the surface
  2. Open-void landscape application that forms a continuous pattern of surface material
  3. Pavement application to place a geotextile on graded slope
  4. Erosion control application with “no slump” concrete mix
Explanation
Answer - B - Grid pavers are an open-void (also referred to as open-cell) landscape application that form a continuous pattern of surface material to control erosion. The grid reinforces areas that are subject to pedestrian or vehicular traffic, while the open void allows for on-site infiltration of storm water and revegetation. Thus, the area has less thermal heat gain and less damage from water runoff and pollution.
