Geotechnical assessments will be carried out this week on a devastating slip in Ravenswood Rd, St Clair.
The slip prompted urgent evacuations.
Ravenswood Rd residents were ordered from their properties as the slip, which shunted cars down the hillside above the street, threatened their homes.
Residents reported the slip, about 8.15am on Saturday, "sounding like thunder" as it tumbled from the hillside and pushed a car through a garage at the rear of one property.
Twelve homes were evacuated immediately following the slip, and one will remain empty for weeks. Resident Ruth Kelsall said she and her family were woken by police sirens on Saturday morning.
There was a knock on the door and they were told to get out. She rushed to gather what possessions she could and get her 13-year-old and 10-year-old daughters ready, when a police officer came back and told her she had to leave immediately.
"Just before that I asked my husband about the cats, what should we do with them?" she said.
"The policeman said we haven't got time to worry about that, we need to get out now."
