Why doesn ComEd put the lines underground?
ComEd can and does install lines underground. Despite being extremely expensive, and sometimes costing several times more than overhead construction, an underground line is not problem-free for trees. During construction tree roots, which provide support and nutrients for the trees, may be cut. Cutting tree roots can lead to tree decline or death or may cause a tree to uproot in high winds. Future maintenance of underground lines may also cause damage to existing tree roots, landscape plantings, and lawns.
