Landscaper for Mercer Island stabilizes hillside


Environmental Construction provides expertise in slope stabilization and hillside landscaping for Mercer Island home.

During a mid-autumn rain storm the super saturated soils caused a slope to fail. After the homeowner cleared the mud away from the walls and windows, Environmental Construction was called on to rectify the problem. We collaborated with soils and structural engineers to creatively stabilize the hillside. Terracing was desired to provide maintenance access to the hillside.

Landscaper for Mercer Island - Environmental Construction Inc.

Environmental Construction Landscape Project:

  • Limited access necessitated the need for craning materials over the house to the rear yard.
  • Series of temporary chutes were erected to help export saturated soils & slide debris off site.
  • After the debris was removed an improved drainage system was installed to direct both surface and subsurface water away from the house and hillside.
  • Engineers reviewed our design for a series of serpentine terraces constructed of one-forth inch steel welded to 2-foot pipe pilings. Pipe pilings were driven with 90 lb. jack-hammers. The steel face was left un-treated to form a rich patina of rust before sealing.
  • A simple yet elegant palette of plants was used to add to the sculptural effect. When viewed from inside the home it looks like waves of flame colored ornamental grasses climbing the hillside.
  • A drilled Columbian basalt column fountain is tucked into a lush fern grotto backed by the steel walls.
Backyard landscaping in Mercer Island requires heavy machinery to move top soil.

We use our heavy equipment to move top soil to the backyard.
