Hi Nick,
Thank you for your patience. TSIRC have confirmed that all three of AECOM’s recommendations were funded and have been implemented in the last ten years.
That includes the recommendations for Saibai from the INUNDATION MANAGEMENT ON SAIBAI, BOIGU AND IAMA ISLANDS Drainage and Seawalls (2012) which were:
- Replace the existing seawall with either a Seabee or rock seawall that incorporates a wave return wall with a crest height at 3.1m AHD. These works are estimated to cost approximately $11,000,000 or $11,300,000, depending on whether Seabee or rock armour is selected.
- Provide protection against inundation from the wetlands at the rear of the community by upgrading drainage and constructing a bun wall with a crest at 2.5mAHD. These works will cost approximately $7,900,000.
- Construct a 1m high reinforced concrete wave return wall around the Cemetery to improve inundation immunity at a cost of approximately $590,000.
Cheers,
Anthony
