This guideline aims to illustrate the environmental consequences of building traditional seawalls and to explain how seawalls differ from natural estuarine foreshores, and to provide those involved in designing, approving, building or upgrading seawalls in estuaries with a range of options to improve the environmental value of seawalls and seawall-lined foreshores. Some techniques will not be suitable for all situations, so always seek qualified assistance in determining which options are appropriate.
Beyond the environmental aspects, many other structural and design issues will need to be considered when seawalls are upgraded or built. It is not the intent of this guideline to cover these. Always seek appropriate advice from qualified professionals.
Note: This guide was first published in June 2009 and was reprinted in 2012 with updated contact details. The version published here is the updated version.
