Figure 1: The development of the parking area behind the Pavilion.

Figure 2: The inlet structure was installed and the porous asphalt area regraded.

Figure 3: A geotextile filter fabric was installed over the soil along with a perforated pipe near the overflow outlet structure.

Figure 4: One side has both coarse stone and finer gravel in place (near) while the other side awaits the second, finer layer of gravel.

Figure 5: The porous asphalt was batched at the plant and applied on top of the rock and gravel bed.

Figure 6: The rest of the area is paved using standard asphalt.

Note:
Figure 1: The area included a large underground detention basin (foreground) and the porous asphalt site (behind).
Figure 4: Note the matting in place until grass grows to keep the fine sediment from washing into the bed.
