LMDIP - Wimmers Carpark Site Planning Assessment

2.1       Proposal

2.2.1 Construction Phase
The proposed works are limited to:
         stripping of topsoil;
         minor earthworks to achieve a suitable finished surface;
         placement and compaction of road base gravel;
         installation of appropriate drainage;
         installation of wheel stops and/or temporary delineation, flagging and signage (if required);
         approximately 60 temporary parking spaces;
         Any temporary erosion & sediment controls required during construction and operation of the carpark will
          be installed; and
         rehabilitation of the site following completion of the Project.

Note: No buildings, no asphalt or kerb and channel are proposed. No lighting, vegetation clearing, new vehicle access to Lake
Macdonald Drive or permanent services are proposed as part of the works.

2.1.2     Operation Phase
 2.1.2.1 Proposed Temporary Carpark
The temporary carpark will provide onsite parking for approximately 60 cars and will be used by John Holland contractors for
approximately 34 months from August 2026 to May 2029. Workers will arrive at the temporary car park in the morning and
then be transported to the LMDIP construction site via shuttle buses. At the close of each day, the workers will be
transported back to the temporary carpark via shuttle buses.

 2.1.2.2 Proposed Temporary Laydown Area
The proposed temporary laydown area will be used primarily to store pre-fabricated building materials and machinery as
needed from time to time. This will include several sea containers with equipment used for the retention structure beams and
concrete form-work required for the construction phase of the dam spillway. There are no stockpiles, or storage of hazardous
or dangerous goods proposed within the temporary laydown area.



2.2 Key Planning Considerations
The works are located inside the currently approved Operational Works Approval footprint.
The proposed works remain consistent with the existing approved use of the land;
The proposed works do not represent a material change to the approved development;
The proposed works sit partially within a mapped riparian buffer – see Figure 1.
A preliminary meeting held with NSC on 6th July 2026 recommended proceeding with an Operational Works application.
This Site Planning Assessment is being submitted along with the following supporting material:
         DA Form 1
         NSC Biodiversity Waterways and Wetlands Overlay Code
         NSC Rural Zone Code
         Traffic Guidance Scheme
