"Undergrounding" refers to burial of our existing overhead utilities. These include electricity (PG&E), cable TV/broadband Internet (Comcast), and landline phones (AT&T). Burying the lines means getting rid of the poles, which can also effect streetlights (we have only one in Los Altos Hills) and 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 lines would be buried alongside or under our roads, possibly under our existing pathways to reduce traffic disruption.
