Update: Early-morning wildfire near SLO High forces evacuations, causes power outages

Update, 5 p.m.:

The Bishop Street wildfire burned only an estimated 15 acres in San Luis Obispo on Tuesday morning — down from the initial estimate of 50 acres, the city said in a news release.

According to the release, the total fire acreage was determined to be 14.7 acres, with 11 acres in the State Responsibility Area and 3.7 acres within city limits.

The initial estimate of 50 acres was made “without a full visual of the extent of the fire and under less-than-ideal conditions of smoke and morning light,” the release said. Later in the day, fire personnel were able to use aircraft and an unmanned aerial vehicle to map the burn scar from above.

According to the release, an estimated 575 people from 329 addresses were evacuated due to the blaze.

“We appreciate the nearby neighbors for heeding all evacuation warnings as we responded to the fire,” the release said.
