WORKS start at the end of this month to replace the ageing sea wall on the eastern foreshore.
The works will also allow for future upgrades to the foreshore amenities.
Curnow Group (Hire) Pty Ltd will carry out the works, due for completion towards the end of the year.
The wall has reached the end of its natural life with water pouring across during storms and high tides.
It will feature a curved design, reflecting the shapes of the Waugal Serpent and extend into the estuary to allow for extra recreation space.
Construction starts at the northern end of the foreshore and work its way south, and there will be no disruption to existing car parking areas.
Pedestrians will also be able to access most areas along the foreshore during the construction period, including access along the length of the foreshore.
About 550m of retaining wall and associated landscaping will include feature paths, walls and seats.
City chief executive Mark Newman said the City would work hard to minimise disruption and inconvenience.
Mr Newman said the council would do everything it could to keep disruption to a minimum but in the early stages truckloads of fill material would need to be delivered each day.
To deliver the fill to the site, trucks will travel south along Mandurah Terrace before taking a detour along Hackett, Sholl and Cooper Streets, exiting along Mandurah Terrace.
To minimise disruption, the contractor will use one entry point to the site at the Cooper Street/Mandurah Terrace roundabout.
Mandurah Terrace will remain open and traffic, cyclist and pedestrian management will be in place at this entry point.
