Furnishing and installing landscaping along I-80 corridor from Gardner Street to Gouger Road, Springfield, IL
This work shall consist of restoring compacted soils and soils that have lost their structure and ability to sustain plant growth. Soil Decompaction serves as a viable method for restoring soil conditions in areas where the topsoil layer has been fully removed and the underlying subsoil has become compacted due to vehicular activity or previous land use activities. Soil decompaction is intended to restore the soil structure and condition to make it more suitable for plant growth. Amendments to the soil may need to be made in addition to the decompaction works if issues are identified following soil testing. Soil decompaction should not be applied within the root zones of trees that are to be retained and protected as it is very invasive and will cause irreversible damage to the tree roots. The decompaction work involves subsoil preparation, incorporation of organic material into the subsoils (compost, peat, etc.), incorporation of additional topsoil into subsoils, and regrading the area to appropriate compaction levels for plant material installation.
