Six apartment units atop a cliff at 320 Esplanade Ave. in Pacifica are being evacuated Thursday morning after a 60-foot chunk of earth fell from the bluff.
Doug Rider, Pacifica's chief building official, said he learned of the latest deterioration at about 6:15 a.m.
“It was very big,” Rider said of the chunk that fell.
Rider said it has not yet been determined whether the remaining residents of the 20-unit building at 320 Esplanade Ave. will need to evacuate Thursday. He was at the site Thursday morning evaluating the situation.
The six units being evacuated are the ones adjacent to 330 Esplanade Ave., which is already under mandatory evacuation due to the crumbling cliff.
Residents of 330 Esplanade Ave. were forced to leave their homes shortly before Christmas. Emergency work then commenced, which involved placing boulders at the base of the cliff to provide a buffer against the waves and stop the erosion.
