Just two properties in Princeton remain under evacuation alert after a geotechnical assessment of a suspected unstable slope revealed recommendations.
On Wednesday, the Town of Princeton Emergency Management announced the hillside above Old Hedley Road had become unstable, and had moved "significantly" in the last 24 hours.
On Thursday, an assessment ruled all but two of the properties on Jacobson Road above Old Hedley Road no longer needed to be under alert.
A precautionary evacuation alert remains in effect for 156 and 176 Jacobson Road.
Old Hedley Road from the Brown Bridge to Old Merritt Highway is closed to all traffic.
The geotechnical engineer's assessment indicated that remedial work needs to be undertaken, but first, hazard tree removal will need to take place.
"We are working on solutions to move heavy vehicles up and down the road and in a safe manner," Mayor Spencer Coyne said.
"The the remediation work has to happen before we can do that."
