The crater left by last year's deadly natural gas pipeline explosion will be filled on Tuesday, San Bruno officials said.
Residents will be allowed to throw a shovel of dirt into the hole.
The mayor, residents and other city officials will hold a ceremony on Tuesday at 11 a.m., the city announced Friday.
A PG&E natural gas pipeline exploded in the city's Crestmoor Canyon neighborhood on Sept. 9, 2010, with the blast and resulting fire killing eight people, injuring dozens of others and destroying 38 houses.
The blast also left a large hole in the ground that has remained in the neighborhood, whose residents last week marked the one-year anniversary of the disaster with a remembrance ceremony at Skyline College.
Contractors working with Pacific Gas & Electric Co. will backfill the hole later in the day, as the utility works to decommission the high-pressure transmission line and restore the blast site.
