Gold Coast Shoreline Management Plan

The Gold Coast Shoreline Management Plan (GCSMP) is an ICZM plan to manage the coastal resources of City of Gold Coast. The EPA encourages the City Council's to produce shoreline management plans for coastlines and tidal waterways within the local authority area.

The Council commenced work on the GCSMP in 2005. The previous key planning document for Gold Coast beaches was the Delft Report of 1971.

Gold Coast Beaches have had periods of severe beach erosion. In 1967, a series of eleven cyclones removed most of the sand from Gold Coast beaches. The Government of Queensland engaged engineers from Delft University in the Netherlands to advise what to do about the beach erosion. The Delft Report was published in 1971, and outlined a series of works for Gold Coast Beaches including Gold Coast Seaway, works at Narrowneck that resulted in the Northern Gold Coast Beach Protection Strategy and works at the Tweed River that became the Tweed River Entrance Sand Bypassing Project.

The Gold Coast seawall in Australia is contained within the Gold Coast's shoreline management plan. The original seawall was laid out following 11 cyclones in 1967 with assistance from coastal engineers from Delft University. The seawall alignment was selected to pick up as many of the older seawalls as possible. The seawall consists of three layers, armour boulders up to 4 tonnes, secondary armour around 360 kg and a clay shale foundation layer. The seawall is 16m across and 6m high and has a front slope of 1:1.5. The seawall was tested in a wave tank to withstand attack from a 1:100 cyclone wave.

A Gold Coast Seawall costs around A$3000 per meter to construct in 2006. The seawall is constructed along a designated seawall alignment along urban sections of the Gold Coast coastline. Non-Urban sections of coastline including South Stradbroke Island and the Southport Spit are not licensed for the construction of a seawall. The Gold Coast Planning Scheme requires private property owners along the beach to construct the seawall at their property at the property owners expense prior to making any investment into their house. The Council constructs sections of seawall that protect public land.
