Beach Renourishment

Prior to winter each year the City undertakes planned beach renourishment along Quinns Beach, Quinns Rocks. Beach nourishment involves the placement of sand, sourced from a local sand quarry, along the beach. The additional sand creates a buffer against the impacts of winter storm events and limits the damage to coastal assets. The locations for beach renourishment are selected each year based upon the level of erosion experienced at each site prior to winter. Renourishment is generally undertaken at the following Quinns Beach sites each year which experience significant seasonal coastal erosion:

  • Quinns Beach, north of groyne 1;
  • Quinns Dog Beach, north of groyne 3; and
  • Quinns Dog Beach, north of groyn 4.

Renourishment locations are not limited to Quinns Beach however, with renourishment often undertaken at Yanchep Lagoon and other locations along the City’s coastline when necessary.

Major erosion events that are caused by winter storms can sometimes result in unsafe beach access and beach use. To improve beach usability and make the beach safe, the City will also undertake reactive beach renourishment when necessary.

October 2021 Reactive Beach Renourishment

Reactive beach renourishment will be undertaken at both Quinns Beach and Yanchep Lagoon in October 2021 in response to the erosion that was experienced at both locations over winter. The beach renourishment will create a safe and accessible beach for the community to use over the coming summer months.

October 2021 beach renourishment works will involve the following:

  • 3000 tonnes of sand will placed at Yanchep Lagoon from the 4th to the 8th of October; and
  • 3000 tonnes of sand will be placed at Quinns Beach, north of Groyne 1, from the 11th to the 15th of October.

Beach closures will be in place throughout the duration of these works.

Update: 12 October 2021

Yanchep Lagoon and Quinns Beach are currently closed while the City completes mitigation works to remove contaminated sand.

The sand was delivered as part of the recent beach renourishment works and the City is working with its contractor to ensure that all sand will be replaced with clean, uncontaminated sand as quickly as possible.

It is anticipated that all contaminated sand at Yanchep Lagoon will be removed by 23 October. Removal of the sand at Quinns Beach will be completed this week and beach renourishment works will be rescheduled for late October.

Should you have any queries in relation to these works please contact the City’s Specialist Coastal Engineer, Rory Ellyard, on 9405 5000.
