Supplemental Projects

[During an investigation of the available daily cover and final cover soils from onsite borrow sources, Aquaterra determined that a large volume of soil under the compost facility could be used for landfill operations. Additionally, a growing market for accepting biodegradable and compostable green waste materials has resulted in a need for additional working and storage space. Therefore, the City requested Aquaterra to design a new compost facility to expand space and obtain the soil under the current facility. The general storm water permit for the facility was terminated in early 2011; therefore, allowing for the removal of two storm water retention basins and making the area available for expansion of composting operations. A site grading plan for the expansion of the compost pad was completed to expand the current 4-acre facility to 6 acres with design considerations for a future expansion to an 8-acre facility. As part of the plan for expansion of the compost facility, Aquaterra designed a temporary compost pad to maintain continuous compositing operations during construction of the new facility. Storm water runoff from compost pad is designed to be collected in a sedimentation basin, then discharged to the Little Blue Valley Sewer District.
