PG&E Completes Post-Shutoff Grid Inspections and Undergrounding Reviews in Alamo and Diablo Foothills

Utility line technicians and wildfire safety engineers with Pacific Gas and Electric Company (PG&E) have completed post-event circuit patrols and equipment audits across unincorporated Alamo and the western slopes of Mount Diablo following the preemptive Public Safety Power Shutoffs (PSPS) triggered by mid-October offshore Diablo winds. In briefings shared with Contra Costa County emergency managers and the Alamo Municipal Advisory Council (MAC) in October 2026, regional utility liaisons confirmed that all affected distribution circuits serving Stone Valley Road, Livorna Road, and Roundhill neighborhoods were safely re-energized after foot and aerial patrols cleared windblown oak limbs. Field crews inspected dozens of miles of overhead distribution spans before restoring full service.

During the October 15–16 Red-Flag warning across Contra Costa and Alameda counties, automated high-definition weather stations positioned along the Las Trampas and Mount Diablo ridgelines recorded low relative humidity and gusting northeast winds, prompting PG&E's Emergency Operations Center to de-energize targeted high-fire-threat segments. Utility engineers noted that motorized sectionalizing switches installed over the past two years narrowed the shutoff footprint, keeping downtown Danville Boulevard commercial plazas and central Alamo medical offices energized while isolating higher-elevation canyon feeders. That targeted switching reduced total customer outage hours compared with earlier countywide shutoff events.

Now that power has been fully restored, engineering survey teams are conducting autumn trenching and subsurface utility evaluations in Alamo to advance multi-year undergrounding and covered-conductor conversion projects across High Fire Threat District (HFTD) tiers. Public health coordinators with Contra Costa Health Services also used the October debrief to urge Alamo seniors and residents who rely on electrically powered medical devices—such as oxygen concentrators, CPAP machines, and refrigerated medications—to enroll in PG&E's Medical Baseline and portable backup battery programs before winter storm outages begin.

Alamo homeowners can look up parcel-specific undergrounding maps, register for address-level PSPS text alerts without a PG&E account, or apply for Medical Baseline rate and battery assistance online at pge.com or by calling (800) 743-5000. Residents can also review upcoming Alamo Municipal Advisory Council agenda items through the Contra Costa County District II supervisor's office.
