EROSION protection measures in Quinns Rocks including groyne construction and pouring sand on to the beach start this week after erosion closed beach access a second time this summer.
City of Wanneroo Deputy Mayor Natalie Sangalli said the City put 360 tonnes of white sand at access points from the Fred Stubbs carpark on December 20 and 21 following significant erosion caused by summer storms.
Cr Sangalli said the measures made the access points safe for the public over Christmas and New Year and cost about $11,000.

“Additional sand will be placed at this location on January 9 and 10 as a short term measure and this beach access point is expected to be re-opened on January 10.
“Additional sand will be imported on a larger scale for beach re-nourishment works.
“This is typically scheduled for March or April each year as a preventative measure against winter storm events.
“However, given recent events, an assessment is underway to consider bringing this forward to February this year after the school holiday period.”
Cr Sangalli said construction of a fourth groyne – part of the long term coastal protection works – would start today, and was due to finish by the end of March.
She said the recent storm did not adversely affect other beaches or coastal infrastructure, including construction of the Sovereign Drive beach access stairs.
“Construction of the Two Rocks beach access staircase is expected to be completed and opened to the public by the end of January,” she said.
Cr Sangalli said the City would continue to monitor the coastline and undertakes regular inspections of the major coastal assets.
“Ongoing monitoring and coastal management information collected by the City in past years has allowed the City to have a better understanding of coastal movements and supports informed decisions on the amount of sand renourishment required each year,” she said.
“The City’s response team also noted significant rubbish was washed ashore that required further clean-up crews to be activated.
“Responsible disposal of rubbish should always be observed when enjoying our coastline to conserve and protect our unique environment.”
