Landfill Design

  • The landfill is lined with a one foot thick layer of re-compacted native clay (Mancos Shale)
  • The landfill is designed to have <3% bottom slope to the retention pond and 4H:1V surface slopes.
  • The landfill is being capped with 4 feet of loosely placed shale and soil.
  • An additional 6-8 inches of native soils, rocks, compost, wood chips, and native plant seeds are placed on the final cap.
  • Vegetation aids with erosion control and provides evapo-transporation to keep water from entering the landfill.
  • An irrigation drip-system is utilized on the cap-layer to promote plant growth.
  • Tire bales are used to control erosion of the soil within the landfill cap.
  • The landfill, as originally designed, was scheduled to reach its capacity in 2010. A 1998 redesign extends this life to about 2048.

Landfill Monitoring

  • There are 27 groundwater wells in and around the landfill site.
  • The storm water retention pond will hold approximately 25 acre feet of water.
  • A landfill gas collection system captures gases, including methane, and converts it to carbon dioxide.
  • Meteorological monitoring is conducted to ensure compliance with federal and state regulations.
