Question
I refer to the Business case proposal for Revetment Work to
Protect and Control Erosion of Broome’s Coastal Cliffs from Town Beach to
Catalina’s, which has received $2.8 million from Lotterywest, and question on
notice No. 3262 asked in the Legislative Council on 16 June 2015, and I ask:
(a) the previous Minister for Lands stated that he was not satisfied there was sufficient understanding of the causes of erosion at the area proposed for revetment at Town Beach, has there been further work to determine the cause of the erosion;
(b) if no to (a), why not;
(c) if yes to (a), will the Minister table the work that shows what the causes of the erosion are;
(d) if no to (c), why not;
(e) is the Minister satisfied the proposed revetment work would not cause erosion or other problems elsewhere along the coastline, including along the foreshore past the Catalina’s development up to the foreshore of Matso’s Brewery, Moonlight Bay and beyond;
(f) if yes to (e), will the Minister table the evidence to show that this is the case;
(g) if no to (f), why not; and
(h) what are the projections for sea level rise for this area of Broome into the future?
Answered on 13 June 2018
(a) Yes, the Shire of Broome has prepared a Coastal Vulnerability Study which included this section of coast.
(b) Not applicable
(c) [See tabled paper no.]
(d) Not applicable
(e)-(f) The Shire of Broome proposed the revetment work to physically constrain further erosion of the cliffs. The development of the CHRMAP has been informed by two community information forums which were held in July 2016 and two community workshops held in August 2016. The workshops provided participants the opportunity to identify and prioritise assets in the coastal zone, assess the consequence of these assets being affected by coastal hazards, and consider a variety of adaptation options for key areas in Broome, including Chinatown, Cable Beach and Town Beach.
(g) Not applicable
(h) The projected sea level rise in Broome in the next 100 years is 0.9 m.
