This is directly adjacent to firehouse and was designed for washing fire trucks. Base was 5 inches of #57 stone, over which a mixture of 1.5” of #89 stone and 3.5” of sand was placed and compacted to 92% Modified Proctor. It is surrounded by a massive asphalt parking lot, which necessitated the installation of Reinforced Concrete Pipes for stormwater. Speaking with a small group of fire fighters stationed at #9, The City of Savannah have employed both Grasspave2 and Gravelpave2 successfully for industrial equipment storage/parking, parking bays for Grayson Stadium (Class A Baseball Farm Team Home for the Mets), and have it designed for other life-safety and tree protection applications and event/ recreation parking throughout the City.

Note flush mounted header curb to protect asphalt from underwashing once ground has reached field capacity (total saturation)

Note that Gravelpave2 elevation is appropriately 1/2 inch lower than header curb to prevent stone roll onto asphalt. Notice how few stones have migrated to the asphalt in a year’s time.
