RPS was the lead environmental consultant for the Point Grey Marina and the 271 ha residential development and land excised for a marina with a capacity for 300 boat pens, situated between the Harvey Estuary and the Peel Inlet, approximately 11 km to the south of Mandurah. The site is located within the internationally protected Peel-Harvey Estuary system, and RPS coordinated and completed all the environmental investigations, agency liaison and stakeholder consultation pertaining to environmental matters for the project. The project was highly contentious and required a specific design, management approval strategy.
RPS prepared Public Environmental Review and supporting management plans and successfully negotiated with the Local, State and Federal Government agencies, the OEPA and the Commonwealth to secure approval for the marina and residential development from the Environmental Protection Authority, under separate Section 38 and 48A referrals, and the Commonwealth approvals under the Environmental Protection Biodiversity Conservation Act, 1999 , extensive environmental investigations and regulatory assessment.
The Point Grey project will accommodate a population of approximately 3,000 people and a marina. Dredging of a new 1.2 km channel across the Peel Estuary to the Dawesville Cut will facilitate passage for boats between the marina, and then the Indian Ocean.
A key challenge for the project is its location adjacent to internationally significant Ramsar wetlands (the Harvey Estuary and Peel Inlet), and careful consideration was given to siting of the marina infrastructure, its orientation and sizing. This culminated in a design that brought the marina partially onshore (rather than offshore), being located on the western side of the peninsula, and in a semi-cleared area of farmland.
These approaches significantly reduced impacts on seagrass communities, waterbirds and remnant fringing vegetation.
RPS services included:
State and Federal environmental approvals
Vegetation and flora studies
Foreshore management planning
Benthic habitat surveys
Marine water quality
The final design was informed by extensive stakeholder engagement with regulatory agencies, special interest groups and local community members. The outcome is a development plan that seeks to retain the significant environmental and landscape features and values that make the site so important.
RPS has prepared the majority of Management Plans required for the projects construction, with several other plans to be finalised once detailed engineering design becomes available. RPS continues to play an ongoing role in bringing this landmark project to fruition.
