Noosa River DMP V1

The proposed dredging works include the following:
    •   Dredging Noosa River for the purposes of beach re-nourishment
              o Dredging of up to 10,000t
              o Existing approved dredge areas expanded to cover the extent from Hilton Esplanade to Weyba
                  Creek, instead of individual local areas along this extent. Exclusion zones within private lease
                  jetty areas still applies.
              o Dredging to maintain 25m buffer from Fish Habitat Area (considering anticipated batters at the
                  time of dredging)
              o Dredging to generally maintain -2.5m AHD depth, but extends to -4m AHD depth along Hilton
                  Esplanade where natural surface level is already deeper than -2.5m AHD and suitable sand is
                  available at depth.
              o Dredge material to be sourced from below LAT at the time of works.
              o Dredge areas are to target shoals in close proximity to the nourishment area and minimise
                  dredge depth by targeting shoals.
              o Dredging to be undertaken with suitable plant (e.g. small cutter suction dredger with cyclone).
              o Dredging is to target uniform extraction across wide area (i.e. avoid digging holes).
              o Material is suitable for on-shore placement (consistent sediment testing report, Pacific Geotech
                  2022)
    •   Nourishment of foreshore
              o Placement of up to 10,000t per year.
              o Material is to be sand suitable for nourishment. Any unsuitable material encountered is not to be
                  placed on the foreshore.
              o Nourishment profile is to be consistent with natural foreshore profiles and transition smoothly to
                  the existing profile at the works extent.
              o No impacts on marine plants (including mangrove pneumatophores) is deemed to be achieved
                  when works are not occurring within 1m of the marine plant or a specialist marine plant expert
                  provides written advice that the nourishment is beneficial to the stability or health of the marine
                  plant or stipulates that a smaller offset would result in no impact.
    •   Existing approved nourishment areas expanded to cover the extent from Hilton Esplanade to Weyba
        Creek, instead of individual local areas along this extent. Exclusion zones within private lease jetty areas
        still applies. No marine plants (including mangrove pneumatophores / roots) to be removed or damaged
        without approval. This is deemed to be achieved when works are not occurring within 1m of the marine
        plant, or a specialist marine plant expert provides written advice that the nourishment is beneficial to the
        stability or health of the marine plant or stipulates that a smaller offset would result in no impact.
    •   No works within private lease jetty areas.
