Bay Area residents may notice lowflying helicopter­s overhead this month as Pacific Gas and Electric Co. conducts aerial firepreven­tion patrols to identify trees and vegetation near power lines.

The utility is inspecting lines in the highfire-threat areas of Alameda, Contra Costa, San Mateo and Santa Clara counties, PG&E spokeswoma­n Andrea Menniti said.

Helicopter­s flying at altitudes between 300 and 500 feet will survey power lines with lidar technology, a lightsensi­ng form of radar, between 9 a.m. and 4 p.m. Menniti said PG&E is contacting residents by phone and mail in advance of helicopter patrols near their homes.

PG&E has increased vegetation­trimming efforts and surveys of power lines following wildfires in 2017 and 2018 that investigat­ors found were caused by the company’s equipment. Damage from the fires created billions of dollars in potential liability that led to the company’s bankruptcy filing.

A federal judge ruled in April that PG&E must comply with a number of new wildfirepr­evention requiremen­ts, including vegetation management, or risk further violating probation. Judge William Alsup is presiding over a case that originated with the 2010 San Bruno pipeline explosion, in which he found that PG&E violated probation after failing to properly report its involvemen­t with a 2017 fire.

In addition to the helicopter surveys, PG&E said in a press release last week that the company is flying seven planes over California every day this summer to spot wildfires before they spread. “Early detection with these patrols can give first responders the critical window of time to quickly contain wildfires,” PG&E executive Sumeet Singh said in a statement.
