Natural Contouring


Cleanup Objectives: Contain an unlined landfill containing nearly 38,000 cubic yards of soil contaminated by waste such as pesticides and asbestos debris

Green Remediation Strategy: Employed BMPs for controlling stormwater runoff and sediment erosion during construction of a landfill cover

  • Installed a woven geotextile silt fence downgradient of construction to filter sediment from surface runoff
  • Added a "super-silt fence" (woven geotextile with chain-link fence backing) on steep grades surrounding the landfill
  • Constructed berms and surface channels to divert stormwater to sediment ponds
  • Emplaced erosion control blankets to stabilize slopes and channels until vegetation was established
  • Hydroseeded the landfill cover with native seed to foster rapid plant growth

Results:

  • Effectively captured sediment at super-silt fence despite heavy rain of Hurricane Floyd
  • Avoided damage of infrastructure used in site redevelopment
  • Reestablished 100% vegetative cover within one year

Property End Use: Redevelopment for office and light industrial space

Point of Contact: Kevin Pavlik, U.S. Army Corps of Engineers
