Our team began the day reviewing the landscape of Expedia’s anticipated waterfront campus with Michal Kapitulnik, Tim Kirby and Heath House of Surfacedesign, Inc. Our mission – find the potential of current site soil for repurposing. Reusing native soil profiles in future blends can have a tremendous impact on future plant acclimation and site maturity. The campus presented a contrasting ecology. Certain areas of vegetation were lush and dense while other areas displayed brown, drying turf; it was clear to the team where our attention would be needed – right?
Exploring the vibrant sections of vegetation, soil was dark, rich and moist to a depth of 14-inches. Its observable characteristics were rated as productive and ideas for soil reuse and logistics were already being explored.
Taking a few steps into neighboring areas, the look of the landscape began to change. A particular section of grassland was going dormant due to irrigation having been turned off as the site was pending demo and construction. Rooting in this area was measured at 4-inches and the soil profile was a fine sand and clay mix. Another section of land, deemed the Rectangle of Death, had dying to dead grass cover; the soil was a sandy gavel mix with obvious signs of compaction.
