MORE landslides and rockfalls are expected along sections of Portland’s foreshore at Nuns Beach and Anderson Point, which have been closed since August.
A preliminary geotechnical report commissioned by Glenelg Shire Council and the Department of Environment and Primary Industries (DEPI) suggests recent crumbling of the cliff-face foreshore are due mainly to groundwater pressure, following long-term rainfall.
This groundwater build-up, particularly with recent record rain, has weakened the cliff structure causing it to slip and collapse, the report says.
“With more rain predicted over coming weeks, further landslides and rock falls are expected,” the shire announced.
“These will continue until much of the coastal instability reduces naturally through a fall in groundwater pressures, or with the help of repairs such as removing loose rocks.
“The area will continue to be monitored.
“Current closures for the beach and pathways around Nuns Beach and Anderson Point will remain until geotechnical inspections confirm the risk has reduced enough for it to be safe for the public again.
“DEPI and the council urge people to observe warning signs and stay off pathways and out of areas of the foreshore that are currently closed.”
Some local residents, including accommodation provider Ken Baker, are concerned that long-term closure will affect the city’s reputation as a tourism drawcard.
He has raised the issue directly with Premier and South West Coast MP Denis Napthine, who referred it to Environment Minister Ryan Smith.
