Ocean Level Rising

The reality of ocean level rising at Cottesloe Beach and its impacts, need to be accurately explained beyond just technical data and facts.  Geotechnical information needs to be comprehensive for the job to be done properly.

Implications of Ocean Level Rising

Many people do not understand full implications for ocean level rising. Many have real problems in visualizing three dimensions and therefore misunderstand the implications of heights and setbacks arguments and the threats to the amenity to beach goers.

It is often just as difficult for professionals to understand ocean level rising ramifications. This is why the general public must be fully informed of the implications of planning decisions in areas near to the beach

Not enough resources have been applied to communicating  the visual impact of ocean level rising and planning decisions.

Accuracy has to be an effective first step in the process.  Levels and alignments of the beach and promenade are critical components for an effective design process.

Ocean Level Rise Eliminates Beach

Beaches Eliminated As Oceans Rise

The reality is that  the ocean level rising will eliminate the current stretch of beach sand. The primary sand dunes will also be lost or greatly degraded over time.

We need to adapt and plan for that eventuality now, before any hugely expensive developments commence. With ocean level rising there could be 20 metres of beach lost over the next 20 – 30 years. .

Extra space must be reserved to accommodate moving the beach eastwards.

Beaches will eventually cease to exist due to ocean level rising and if current development plans continue unchanged, there will be no allowance for a future Cottesloe Beach, as the ocean naturally tries to move it eastwards.

Ocean Level Rising Moves Beach Eastwards

We as a community and electors of government simply need to intervene now before expensive developments begin to evolve.

This was recommended as early as 2004 and anticipation of ocean level rising was included in our original  report: Cottesloe Foreshore Plans carried out for the Town of Cottesloe. Climate change must be addressed. In other areas of this website we have written extensively on the problems created by lack of population control, by energy consumption growth and the need for improvement in our built environment to help greenhouse gas reduction.

Reposition Beach Developments

Apart from moving Cottesloe Beach eastwards we also need to extend a development zone eastwards, to make it possible for economically viable projects to proceed over time.This is a key element for creating a future beachfront of value.

We also need full morning sun to reach the promenade, key social areas and the beach along the waterline.

If a wall of shade prevails, these areas will no longer be attractive to the public.

Oceans To Rise 1-1.5 Metres

It is obvious that inaction over ocean level rising due to climate change is ensuring that we can expect the full one metre rise.

In fact, it is more likely to be 1.5 metres due to the slow action in abating CO2 and other greenhouse gasses in the atmosphere by most of the developed world.

My suggestions regarding moving the beach eastwards should be considered simply as ‘damage control’.

Issues such as public parking,  attractive access to the beach by nearby residents and the maintenance of heritage views need to be considered in any integrated vision for the precinct.

Key issues needed for a 100-year plan: Cottesloe Beach

  1. Moving the beach stage-by-stage eastwards allowing 30 metre extra buffer zone
  2. Setbacks of 30m from Marine Parade for all new developments
  3. Identifying a development zone for commercial development expansion, subject to the proposed new 30 metre set back
  4. Establishing rear access to the central car park off Marine Parade, to reduce summer car congestion.
  5. Establishing low-key 2-storey height development as a front to a new 2 storey car park and reduce existing parking at the CBH/Indiana precinct.

Planning this beachfront is really a very complex task.  It should not be oversimplified.The issue of ocean level rising is a serious matter.


Green Home Plans

If you are planning an environmentally-friendly new building, or are looking to add renewable energy technology to an existing property, you are not alone. In recent times, the importance of designing in accordance with green home plans has really gained popularity. It is important to start by getting the orientation of the building right. This varies from location to location, so to understand the the sun’s angles and the climatic region of your planned location,  it is important to have scientifically correct data on which to base your decisions.

Changing Traditional Building Methods

People are beginning to understand the damage caused to the environment by traditional building methods and they are actively looking for green architects to undertake their new buildings, extensions or upgrades to existing homes. For details on architects and building methods please view our other articles under the Consumers Section of this website.

Using Renewable Energy

Millions of homes and businesses across the world are using renewable energy sources, such as solar panels and wind power, to harness the planet’s natural resources and reduce our dependence on expensive and depleting fossil fuels.

Buying Green Building Products

Many people now view the purchase of green building products as a long-term investment, reducing the running costs of a property, while also helping to reduce their carbon footprint. Green building supply companies are booming and an increasing number of energy efficient devices are becoming available on the market.

Whether you are adopting  green home plans for an entire property, an extension, a greenhouse,  garage or  planning to retro-fit an existing building, there is a wide choice of building products available to help you complete your project. Read the article on ‘green building products on this website.

Choosing Green Building Materials

If you have specific green home plans prepared already you will now be able to find a wide range of construction materials to choose between for the best environmental results. However, a little preparation will be required to ensure that any  green home plans are executed for the best results in energy efficiency, climate control and comfort.

While shopping shopping for eco-friendly building materials, it’s important to consider the many natural materials available, including but not limited to earth, wood, straw, bamboo or stone. The choice is now vast – new environmentally sensitive  products are being developed for the market continually, in a bid to satisfy the demand from green building projects.  Our expert green building design guideLow Energy Buildings in Australia” is now available in the shop. We recommend you research the information in this guide to help you select the orientation of your building, the placement of windows, your choice of  building materials and their contribution to a successful low-energy building design.

Adopting Sustainable Architecture

Ideally, you will need to find a balance between practicality and great aesthetics. Green building incorporates many different elements and should always embody a high level of sustainable architecture. Many people use the services of a specially trained environmental architect to help them plan and design their projects and turn their green home plans into viable and sustainable options.

Obtaining The Stamp of Approval

Your architect can also advise you on ways to obtain green building certification on your property, which can be extremely beneficial when it comes to selling your home.

Considering The Cost

When you are working with your architect or designer on your green home plans it’s vital to consider your ongoing requirements, before commencing with any building work. This will ensure that you get the best possible results to suit your lifestyle and needs.

Carefully reviewing the number of rooms you think you need may lead to a guest bedroom doubling as a multi-purpose room. Reducing the number of rooms or their dimensions will reduce building costs and ongoing energy consumption.

Searching For Help

There is now a vast range of websites available to help you get any green projects off the ground. Using the internet, searching websites and special interest forums will uncover tips and ideas for the implementation of new technologies in a practical and cost-effective way. Use the ‘search’ button on this site for a subject you wish to read in more detail or contact us with your questions.

As increasing numbers of people look towards the use of renewable energy sources as a way to make a positive contribution to the planet, there will be increased demand for specific green home plans and architects and designers will add energy efficient design training  to their skills.
