Semaphore's Coastal Environment

Coastal Management in Hastings is effective economically, socially, environmentally and is sustainable for the future.

Seawalls are also strategies that Cronulla and Collaroy implement on their beaches. However, the seawalls in Collaroy are buried under the sand and are only visible after large-scale erosion events. Whereas Cronulla beach’s seawalls are visible and reduce the scenic

Caloundra is a coastal town within the Sunshine coast region, surrounded by beaches such as Bulcock Beach, Kings Beach, Golden Beach, Dicky Beach and the Pumicestone Passage. Caloundra provides a range of outdoor activities, especially as a result of its lush natural environment, promoting a heathy life style and attracting tourism and locals through recreational activities. The local economy of Caloundra is primarily seasonal, and is currently suffering due to competition from surrounding areas such as Kawana Town Centre, South Caloundra (AURA) development, and Maroochydore developments. In response to this, the Sunshine Coast Regional Council has developed a Master Plan to revitalise the CBD of Caloundra, attracting tourism and income back

The Sandon Point was considered a potential State Significant site under the State Environment Planning Policy (Major Development) 2005. In April 2006, the Minister authorised Stockland and Anglican Retirement Villages to submit a concept plan for the development of Sandon Point, Wollongong. The concept plan was approved in December 2006. In November 2007 the Minister’s approval was challenged in Walker v Minister for Planning [2007] NSWLEC 741, 174 LGERA 127 due to the Minister’s failure to take in to consideration the principles of ecological sustainability, specifically, climate change and flooding. The Court of Appeal found the Minister guilty of failing to consider public interest in the concept planning stages and made it mandatory to be considered in the development approval stage.

Collaroy beach is located 16km north of Sydney’s CBD within Warringah Council's local Government Area. It is approximately 3.6 km long from the local Collaroy surf Club to the Narrabeen lagoon in the north. It had extensive development in comparison with other beaches. There are over 120 plots of land and 293 residential units within this area. Many buildings are many stories high to accommodate a large number of wealthy people. This high level of development has posed a serious risk to property due to the effects of erosion, which has shaped Collaroy beach many years along with other natural processes such as deposition. Erosion continues to occur as the land is pushed inwards at a relatively rapid pace. A year 10 grade from Redfield College

The aim of the fieldwork was to investigate the management and maintenance of Shrimptons Creek Parklands for encouraged use from the local community. The investigation would focus on the purpose/use of the parklands by the general population, the accessibility of the parklands and the environmental

On the 14th of March 2011, year 10 went to Cronulla Beach to investigate how people use and interact with the coastal environment. We investigated three main things and they were:

* The efforts of “Terrigal Lagoon Bushcare” have been largely successful in keeping the lagoons around Terrigal ecosystems. Their actions have helped the native plants compete with the introduced species.

The aim of this report is to investigate Long Reef and Collaroy Beach’s coastal management.

Culburra beach is one of the only beaches that have not undergone any human reforming and remains in its natural state. Culburra Beach does not have any man-made sea walls, boulders or human reforms. It does however have a natural sea wall consisting of sand dunes and natural vegetation, that separates the sea from the first line of houses. In order to ensure that Culburra beach continues to flourish, all humans have to do is ensure they do not pollute the beach and waters and build houses too close to the natural beach. Culburra Beach has been able to continually achieve a natural cycle as the waves bring sand into beach and then take the sand back out into the ocean. This forms a natural process and recurring cycle, allowing the beach to function

tides. There are also many programs which help to ensure the stabilization of dunes, these include the planting of new vegetation to combat erosion, fencing and designated

How effective are the coastal management strategies used at present in your local beach area?

This leaves the sand dunes more susceptible to erosion causing blowouts and disrupting the succession of vegetation in the area. This has been a problem at Studland Bay in Dorset on the south coast of England. Persistent human leisure activities on the dunes has led to substantial erosion in some parts of these dunes which has meant that Management programs have had to been introduced by English Nature. Sand dunes help absorb the pounding of high waves and reduce overwash flooding in storms.

In an attempt to combat erosion and interest more people in visiting this area an ongoing project has been implemented along Long Beach and Nutgrove Beach. The project aims to reduce the rate of erosion and make the area a desirable place for people to visit for many years to come. One of the most recent additions

The aim of this strategy is to keep the beach maintained and to try and stop the damage to the coast, this that need to be protected are the sand along the beach if not all that will be left along the beach would be rock and clay, the houses along the shore will also be effected by storms. This strategy is still ongoing but seems to be working out so far for Semaphore Beach. (The picture on the side shows a build-up of sand dunes along Semaphore beach in 1997)
