A new seawall will help tackle erosion at Algies Bay. Finishing work on the southern side of the boat ramp completes the seawall project as the northern side was done several years ago.

Local Board Chair Beth Houlbrooke says public consultation helped shape the project and, while it took slightly longer than planned, the result speaks for itself.

“People love the foreshore and now it is protected for years to come. Coastal projects involve working around tides and difficult ground conditions which can extend the timeline.

“The work used specialist techniques to construct the masonry stone seawall, retaining walls and steps from the foreshore to the reserve.

“This iconic seawall offers protection, a place to walk or just sit and relax while enjoying magnificent views out over the bay.”

Construction took seven months and features:

  • a seawall consisting of 47 metres of rock masonry and a height range of 1.5m to 2.1m
  • a series of timber retaining walls stepping down the reserve’s slope starting behind the seawall
  • a landscaped keystone wall located at the southern end of the reserve
  • a path network across two levels; with the lower path connecting the esplanade reserves and the higher path and steps connecting the car park, playground and lower path
  • five picnic tables, in-situ seating built into the retaining walls and a drinking fountain.

Still to be completed is a footing around the eastern edge of the boat ramp, bevelling the edges of the stabilised sediment capping over the sewer pipe and manhole to prevent tripping and four decorative posts featuring motifs and carvings.

Work has started on the Gordon Craig Place car park and driveway. We aim for boaties to have access to the boat ramp from late next week. However, all work, is weather dependent and the plan is to complete car park by 12 April.
