Context

Introduction
This report presents a framework dredge management plan (DMP) for undertaking foreshore management works along the Noosa River foreshore adjoining Noosa Harbour Resort and Las Rias Holiday apartments. This framework DMP sets the standards for environmental management to be adopted by a Contractor for these works and supports applications for environmental approvals. The Proponent for these works will be the collective body corporates of Noosa Harbour and Las Rias or a project manager acting on their half.
Prior to commencement of any works, the actions within this framework DMP are to be implemented by the Contractor and a detailed DMP is to be developed.
Objectives
This DMP constitutes a framework guiding the Contractor and associated parties to meet any applicable environmental legislation requirement, achieve best practice environmental management and anticipated regulatory requirements. This document aims to provide all relevant information, systems and procedures that will allow the Proponent and the Contractor to prevent or minimise potential environmental harm.
Specific objectives of this DMP include:
Identify sensitive receptors and potential impacts from the proposed activities
Ensure works are undertaken in a manner which avoids, manages and minimises potential environmental harm and protects receiving environment and sensitive receptors
Ensure works are compliant with legislative requirements and existing approvals
Ensure works meet the environmental and planning outcomes established under State and Federal government policy
Manage all waste streams in accordance with the waste management hierarchy of avoid, reduce, reuse, recycle, treat and dispose.
Activity Description

Project Overview and Location
The Project works consist of the following key elements:
Repair of a revetment wall
Dredging and pumping sand to:
Construct geotextile sand bag groynes
Nourish the foreshore, including complete burial of the revetment wall.
This will be supported by laydown and stockpiling of construction material at nearby parks, with materials to be loaded onto marine barges and transported to the works area.
Figure 2.1 shows the location of key project elements.
Construction Methodology
Overview
It is anticipated that all works would be undertaken by a single Principal Contractor, noting that aspects of the development may need specialist subcontractors (e.g. dredging contractor, marine contractor). The works would be undertaken with the following general sequence:
Mobilisation to site, including establishment of laydown areas
Reprofiling to prepare the site
Reconstruction of deteriorated segments of the revetment wall
Dredging and delivery of sand to fill geotextile containers in groyne configuration
Dredging and delivery of sand to bury revetment wall and groynes, including reprofiling works
Demobilisation.
Details of key components of construction are noted below. Note that the specific methodology may change depending on the Contractor appointed and would be confirmed through a Marine Execution Plan and Construction Management Plan.
Construction works are expected to take a period of 16 weeks and would require the temporary closure of this area during this time. While the foreshore is open to the public, due to its current eroded state, there is limited existing access and therefore disruption to public access would be limited.
Revetment Wall Works
While there is capacity for small excavators and similar plant to access the beachfront for construction works, access is not appropriate for trucks delivering rock and other material for construction. Additionally, there are no appropriate areas along the foreshore for the stockpiling of rock and material for construction. Therefore, it is intended that rock and geotextile material required for the revetment wall repairs would be delivered by road to temporary stockpiling areas located at the nearby Quamby Park and/or Bicentennial Park, subject to local approvals and site management arrangements to be agreed with Noosa Shire Council.
From these sites, material would then be loaded to marine barges and progressively delivered to the site for unloading and placement by excavators. These parks both have sloping foreshore access and would not require the use of any temporary structures (e.g. marine offloading facilities, pontoons), although beach access matting may be used to reduce potential erosion risks. The location of these stockpiling areas is shown in Figure 2.5 and included in the accompanying design pack. Following completion of all works, the contractor for the works would be required to ‘make good’ any disturbance in these parks to the satisfaction of Council, subject to relevant management arrangements.
All construction works on the foreshore of the site would involve excavators and similar plant.
Sand Sourcing and Groyne Construction
Following completion of the revetment wall repair, sand sourcing and groyne construction works will proceed in parallel. This will involve dredging sand from the sandbank immediately north of the Noosa River channel with a cutter suction dredge, with material then hydraulically pumped back to the site and directly into the geosynthetic containers. These containers will be placed in the configuration of the groyne, with additional layers added as the base layers are completed. Excess water from the dredging will filter through the bags and back to the Noosa River.
Once the groynes are completed, additional sand will be dredged and pumped to bury the revetment wall and groynes and achieve the design beach profile. This will involve some support from an excavator to ensure appropriate profile is met. Excess water from this placement will flow back to the Noosa River.
The location identified for sand sourcing is shown in Figure 2.4 and in the detailed design plans accompanying this application. This site has been chosen as it immediately adjoins the main channel and therefore can be dredged in a way that does not cause change in local hydrodynamic conditions. Dredging would occur across the footprint to a maximum depth of 1m to ensure only sand is targeted. The footprint shown is currently 7054m2 with a total capacity of 7054m3 if cut to a 1m depth, well in excess of the sand requirements for the project.
Pumping of sand will require the use of pipelines from the dredging area to the site. To avoid navigational safety risks, the pipeline will be sunk under the channel. Due to the proximity of the dredging area to the site, booster pumps are unlikely to be required.
Following completion of dredging works, the dredge vessel and associated pipe will be demobilised. All land-based plant and site equipment will also be demobilised.

Receiving Environment and Key Project Impacts

The lower Noosa River is part of a wave-dominated barrier estuary, with significant sand shoals formed throughout the river. The northern banks of the river are mostly undeveloped and features extensive mangrove and coastal forest communities, with other significant remnant vegetation also present at Noosa heads (across the river from the works site) and in upstream portions of Weyba Creek. The works site itself does not feature vegetation due to the developed and heavily eroded nature of the land but forms part of the broader mosaic of habitat and environmental values associated with the river. Within this area, key environmental features of note are:
Sand shoals and intertidal habitats utilised by resident and migratory shorebirds and waders, including areas of significant shorebird roosting and feeding areas near the river mouth
Generally low turbidity and high quality marine waters, with no major industrial discharges
These waters are scheduled as high ecological value (HEV) under the Environmental Protection (Water and Wetland Biodiversity) 2019, carrying a management intent of maintaining indicators for all environmental values (EVs)
Periodic seagrass, although this fluctuates with the dynamic sand shoals.
The area is also a popular recreational area, featuring boat-based activities by residents and tourists together extensive use of the foreshore. The works site is also immediately adjacent to resort areas used for recreational and tourism purposes.
Within this context, the key environmental risks of the Project requiring management are:
Generation of a turbid plume, including of contaminants within dredged material either through dredging and placement
Exposure of ASS through dredging and placement above MHWS
Loss of core shorebird roosting and foraging habitat
Strike of marine megafauna by vessels
Release of pollutants into the marine environment
Interference with recreational and commercial marine traffic.
These form the basis of the management measures relevant to the Project.
