Coastal Planning Western Australia

Reading the draft State Coastal Planning Western Australia policy document it appears that the new policy for coastal planning in part seems to be based on some ‘convenient truths’ that support current government positions on coastal development.

Limits on Building Heights

The first anomaly in the new draft policy document for coastal planning Western Australia, compared with the old document is the conditions covering “the maximum heights adjacent to coastal boundaries of 5-storey maximum. This limit to be less where community support for lower height is evident.’

This limit has disappeared from the new document, leaving the question of height completely open to interpretation.

Ambiguity Leads to Misinterpretation

The correct interpretation simply did not happen with Cottesloe Beach LPS3 proposed planning scheme. This omission to references to height limits appears to conveniently suit the current government’s stance.

Height Limits for Coastal Planning Western Australia

If credibility is to be achieved with this document height limits based on objective criteria must be clearly defined in scientific terms. The final writing of  the Coastal Planning Western Australia policy document represents a unique chance to protect our coastal environments for generations and reflect great credit on the Barnett Government.

Regional Government

The secret to solar and renewable, as well as general sustainable and clean forms of energy, to be successfully introduced in this 21st century is the effectiveness of policies and legislation of regional governments.  One of the immediate concerns with inaction at this level will be the horrific damage that will be caused from ocean level rises.  These are already happening and accelerating.

Throughout the planet, Climate Change due to the excessive use of fossil fuels is increasingly causing problems for our coastline developments.  The key to solving and adapting to unwanted changes in sea levels is effective Regional Government.

All around the planet sea levels will raise by varying amounts and the reasons for this is the forces of gravity from the moon, the sun and large planet like Jupiter and the bulging of oceans at the equator (mainly due to the gravitational effects of the moon).  Of course the moon caused tidal variations will create odd spasmodic changes in sea levels, never experienced by mankind before in the period that human kind has lived in earth. It will wreak havoc on all costal developments starting from 2020 onwards.

There is a wake up call for all governments (particularly in the developed world) to start taking into account sea rises for the next 100 years.

This will mean that some development will have to be demolished and moved inland and buffer zones created for all new developments (it goes without saying that they should be as carbon ‘neutral’ or ‘minus’ as possible).

Here are some papers that used Cottesloe Beach in Western Australia as a case in point:
