3rd March 2004
The purpose of the Port Geographe Action Group is to provide the community with support, by liaison between the residents, the community in general and the signatures to deed of the Port Geographe development.
The Port Geographe Action Group’s agenda is to see the implementation of a sustainable long term solution to those problems, which may include ensuring that the deed of agreement entered into by the Developer, Shire of Busselton and Department of Planning and Infrastructure is strictly adhered to.
Where non-compliance to the deed is identified, The Port Geographe Action Group will seek immediate corrective action be undertaken by the applicable signatory(s), to ensure the deed of agreement is adhered to. Failure to take immediate action by any signatory of the deed is likely to result in litigation being pursed by the Port Geographe Action Group.
The Port Geographe Action Group is pursuing the following immediate corrective action by the applicable signatories of the deed;
1. All seagrass wrack currently on all beaches west of the Port Geographe development must be remove offsite without delay.
2. None of the above seagrass wrack is to be pushed into the ocean, but retrieved and physically removed offsite.
3. The current shortfall of clean sand on the beaches east of the Port Geographe development is to be replenished without delay. Restoring the beaches east of the development. This balance of sand used to replenish these beaches, must not be taken from the already depleted designated sandtrap / weed wrack area or from those beaches west of the designated sandtrap / weed wrack area.
4. Any build up of seagrass wrack on the beaches west of the development during the calendar months of August, September and October, must be removed offsite and cleared of any seagrass wrack at the end of each month.
5. No seagrass wrack is to be pushed into the ocean. The beaches are to remain clear of any seagrass wrack and free of offensive seagrass odours.
6. Annually, during the calendar months of August, September, October and November, a monthly sampling / monitoring and reporting program be implemented to examine the following and made available to be public;
i) Seagrass wrack build up on the beaches west of the Port Geographe development.
ii) Levels of noxious gases (typically Hydrogen Sulphide) produced by rotting seagrass wrack.
iii) Condition of ocean water in the recreation areas east and west of the Port Geographe development.
impact of the beaches east of the Port Geographe development.
7. A coordinated study be undertaken by a suitable qualified person is to be commissioned immediately to evaluate the effectiveness of the current methods defined by the development deed of agreement for seagrass management, sand bypassing and erosion management.
Recommendations from this study must be based on modelling carried out to replicate conditions at the Port Geographe development and consider methods to achieve the following outcomes:-
i) Dredging from the current designated sandtrap / weed wrack area for the Port Geographe development to cease. With no future need for dredging from this location.
ii) Efficient and effective means of dredging within the harbour entrance to ensure safe passage in and out of Port Geographe and an effective means of dredging only clean sand from this location to be utilised in the maintenance of beaches east of the Port Geographe development. Any material other than clean sand must be removed offsite rather than being dredged and placed within the recreation areas.
iii) No clean sand is to be removed from the beaches west of the Port Geographe development.
iv) Identify the most effective means to reduce the need for sand replenishment, and find ways of non intrusive maintenance for those areas that would otherwise be susceptible to erosion. This may include;
§ Modification to the current groyne structure by re-directing / aligning one third of all existing groynes in an easterly direction.
§ The length of these modified groynes be proportionally shorter as they progress east. See attached diagrams – Current Groyne Structure / Proposed Groyne Structure.
§ A natural beach be allowed to form to the northern most point of the western groyne at Port Geographe development.
Should any of the immediate corrective actions identified above not be acted on by the applicable signatories of the deed, the Port Geographe Action Group will notify both the applicable signatories and the general public of its intention to pursue legal action to compel the taking of remedial action, and seek appropriate compensation as applicable.
