Mannum - Residential Marina

The proposal

The ‘Mannum Waters’ Residential Marina proposal was declared a Major Development in 2005 and was the subject of an Environmental Impact Statement (EIS) process. The proposal was granted a Development Authorisation by the Governor on 30 October 2008. Construction started in June 2010, with the major earthworks, marina basin, boat ramp, constructed wetlands and initial stages of the residential land-division now completed.

The proponent for the marina development, Tallwood Pty Ltd, now seeks to modify the layout plan and design of the site to incorporate a proposed holiday village and adventure water park.

The initial declaration notice has been varied to include recreational and tourist development land uses. The original Guidelines and EIS did not address these uses, so new Guidelines have been issued for an Amendment to the EIS, in accordance with Section 47 of the Development Act 1993. Once the proponent has prepared the Amendment to the EIS, it will be released for public consultation.
