What is Undergrounding?

"Undergrounding" refers to burial of our existing overhead utilities. These include electricity (PG&E), cable TV/broadband Internet (Comcast), and fiber and landline phones (AT&T). Burying the lines means removing the poles, and relocating some wireless transmitters (like those used by PG&E for collecting smart meter data). Most undergrounding projects now place transformers and switchgear in surface pad-mounted enclosures for reliability. The wires and conduits are buried alongside or under our roads, possibly under our existing pathways to reduce traffic disruption.
