Narrative
On february 06, 2019 at approximately 13:14 hours, pg&e was notified of a third-party dig-in with subsequent ignition near 3300 geary blvd. In san francisco.

Police and fire personnel evacuated multiple buildings surrounding the area (approximately 1 block in each direction of the incident- approximately 100 people) and controlled the spread of fire. No injuries or fatalities were reported. Pg&e's m&c crew arrived on-site at 13:29 hours, and the area was isolated by 15:36 hours. Repairs were completed, and service restoration began on 2/7/19.
