Coastal vulnerability in Gosford City
There are approximately 14 kilometres of beaches within the Gosford LGA, extending from Patonga in the south, to Forresters Beach in the north.
The pressures on the natural resources along the coast are significant: population growth, increasing residential development needs, coastal development and tourism.
The increased usage of the coastal zone is also having a greater impact on the natural resources and environmental value of Gosford's open coast and Broken Bay beaches.
Gosford beaches are amongst the most dynamic on the east coast of Australia.
Beach and dune erosion during storms has occurred on several occasions over recent decades, resulting in the loss of several buildings and threat to much of the beachfront development.
The worst erosion was experienced along North Avoca, Terrigal and Wamberal beaches, during 1974, 1978 and, to a lesser extent, 1986.
Severe erosion during these storms also occurred at Macmasters/Copacabana and Forresters beaches. While not directly threatening development, this erosion has raised questions relating to dune stability and the development thereon.
Historically, coastal processes have threatened sections of this coastline, with particular reference given to the impacts of erosion at Wamberal Beach in 1974, 1978, 1986 and 1997.
Damage to public assets and impacts upon recreational amenity has also been experienced at other beaches in the Gosford City area.

These issues are likely to be exacerbated as a result of postulated climate change impacts and projected rises in mean sea level.
