Why doesn PECO put the lines underground?
Since 1984, PECO has and continues to install lines underground in new construction developments. 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.
