❓ A WA parliamentary question probes the establishment, budget, scope, and rationale behind a coastal mapping project aimed at assessing sea-level rise risks, referencing a 1988 study and questioning the project's limited geographical focus. The Minister's response clarifies project details, funding, and justification.

QuestionView source ↗
In respect of the article in
The West Australian,
‘Sea rise risk spurs coast map project’, of 11 April 2009 -
(1) When was the coast map sea rise risk project established?
(2) When was the coast map project budget of $1.6 million agreed to by cabinet?
(3) When did work on the 3D map of the land and sea floor, from Yanchep to Cape Naturaliste, commence?
(4) Was the Minister for Planning or the Department aware of a series of 60 maps (job number 880589) produced by the Department of Land Administration in 1988 in respect of predicted coastal climate change impacts?
(5) Will the Western Australian Planning Commission compare their predicted impact with the 1988 two metre sea level rise predictions?
(6) Why is the study limited to the land and sea floor from Yanchep to Cape Naturaliste when the 1988 study identified Carnarvon, Mauds Landing, Port Hedland, Derby and the Karratha region as being at risk?
(7) Did the Minister or the Department advise other Departments or Ministers of the plan to 3D map the land and sea floor from Yanchep to Cape Naturaliste?
(8) If no to (7), why not?

(1) The Two Rocks to Cape Naturaliste - LiDAR bathymetric and seabed survey project was recommended by the Western Australian Planning Commission and approved by me on the 25 March 2009.
(2) The project and its budget did not require Cabinet approval as no new funding has been used for this project.
(3) The LiDAR contract work commenced on 2 April 2009.
(4) The Department of Land Administration maps no longer exist. Enquiries revealed that these maps would have been too coarse to be of any value.
(5) No. The use of crude inundation mapping is not considered to be a valid means of predicting sea level rise impacts. Crude inundation methodology gives no consideration to a multitude of relevant variables such as coastal processes (e.g. currents, rips, waves, winds), underlying geology, existing protection structures, storm events, historic trends.
(6) The Two Rocks to Cape Naturaliste area is by far the greatest, current and proposed, concentration of coastal population and development in the State. As a region, this area will be potentially subject to the greatest overall impact of sea level rise and therefore, of highest priority for the acquisition of high quality, high resolution baseline data from which modelling can be undertaken.
While it may be desirable to acquire high resolution bathymetric data for the entire WA coastline, it is an expensive process and therefore limited by availability of funds and resources.
(7) Key stakeholder departments involved through the Western Australian Land Information System (WALIS) Marine Group.
(8) Not applicable
