               Assessment
               Noosa Council engaged ‘BMT Commercial Australia - consulting coastal engineers’ to peer review
               the Applicant’s coastal erosion assessments. These included a Royal Haskoning DHV [RHDHV]
               report dated 18 June 2024 and an updated report by Moffatt and Nichol dated 22 January 2025.
               Areas of dispute between the consultants related to the relevant storm tide level applicable to the
               site and the impact this would have on the extent / width of any erosion prone encroachment.
               Ultimately both consultants agreed that an erosion prone area of 85 metres measured from the
               seaward toe of the frontal dune (2.3 metres AHD) was applicable, based on a storm tide level of
               1.79 metres AHD. A storm tide level of 1.79 metres AHD is approximately a 1 in 300-year ARI
               event.
               The Moffat and Nichol (2025) assessment has included a reassessment of the EPA, applying the
               requested storm tide level of 1.79m AHD. I confirm that we have reviewed the information provided
               and accept the recalculated EPA width of 85m.

               An 85-metre erosion prone area encroaches into the eastern portion of the site by approximately
               11 metres. This degree of encroachment involves approximately 5 metres of the proposed eastern
               building.




               Further discussion with BMT Commercial Australia about whether the building footprint should be
               moved out of the erosion area concluded that a condition could be applied to ensure that any
               building footings within the erosion area was to ensure free movement of sediments through natural
               processes.
               The condition provided by BMT Commercial Australia for Council is included within the decision.

               4.1. Referral Agencies
               Not Applicable
               4.2. Internal Council Referrals
               The application was forwarded to the following internal Council officers for review and/or comment:
               •    Senior Development Engineer, Development Assessment
                    - The most significant concerns with the site were the potential for coastal erosion. It is
                       understood that this issue has been addressed separately by the planning officer.
