Underground Utilities Projects
Transportation and Public Works is now Sonoma Public Infrastructure - Website updates coming soon!
PG&E has two major efforts focused on undergrounding electric distribution lines: the 10,000-mile undergrounding program and Rule 20. The 10,000-mile undergrounding program is focused on reducing wildfire risk and is utility-driven. Rule 20 work is done under provisions of the company's Rule 20A, an electric tariff filed with the California Public Utilities Commission, and does not require projects to address wildfire risk. TPW acts as liaison between the utilities and property owners within an established underground utility district.
