Figure 4: Approved Wall Typical X-Section [NRS-007]

Further review of the preferred construction materials has revealed the following:
     .    The concems expressed by the contractor [see section 3] potentially reflect some additional disadvantages for use
          of sand-filled geotextile contianers in this location.
     .    Access along the nourished beach eliminates the need for clearing for access to the end of the Noosa River Spit.
     .    Discussion with Hastings St Association has resulted in an acceptable delivery timeframe (with deliveries being
          restricted to 9am   4pm Mon Sat). It is expected that deliveries will be limited to a 2-3 week period.
                              -          -




     .    There is limited usage of the foreshore in this location given the proximity of the main channel so being user-
          friendly is less critical in this location.
     .    The higher cost is offset by potential costs of re-establishment.
          While removal of rock is not as simple as sand-filled containers, it can be achieved in the event that this is required
          [although it is the intent that the works remain to protect Noosa R Spit in the long term).

After further review of the above and discussion with relevant agencies and stakeholders, it is proposed that a section of the
wall which is closest to the bank and exposed to the highest currents be constructed using rock [Figure 6 & Figure 7). A
revised construction methodology is included in the Concept Environment Management Plan [rev C].
