Rain, Rain, Go Away

Infiltration Test

We shot this video March 13, 2017, after a rainy weekend on a residential lot in Broadmoor that participated in the Front Yard Initiative. We tested the permeable  Truegrid driveway with help from Anthony Kendrick of Construction EcoServices. According to the results of the ASTM C1781 Test Calculator, the infiltration rate is over 800 inches per hour, with 5 gallons of water infiltrating within a sealed 12″ area in 42 seconds.  The permeable driveway was installed over a year ago.

The TrueGrid was sourced from Quality Sitework Materials and installed by Evans + Lighter Landscape Architecture.
