Redland City Council has released updated artist impressions of the Toondah Harbour and Weinam Creek redevelopment schemes showing the extent of the development with marinas and parking.
A market assessment report from Jones Lang LaSalle said there would be adequate demand for a 400-berth marina at Toondah Harbour and for units and apartments.
However, it also said viability depended on discounts on infrastructure charges and added that lenders were not supportive of marina developments.
It said to provide certainty to the market, a detailed dredging plan was needed along with solutions for marine traffic management and cost-effective delivery and positioning of revetment walls.
The report said the retail component of Toondah Harbour would cater to the local catchment and provide a point of difference to the Cleveland CBD.
Jones Lang LaSalle said the supportable retail space for Toondah Harbour was between 1500sqm and 2500sqm depending on the extent to which a marina was developed and excluding a function centre.
The report said the main retail component would be a waterfront pub or hotel and function or event centre with accommodation developed over time.
A local convenience grocery shopping store would cater for residents and ferry passengers.
There will be no further public consultation when the updated schemes are published and will open the way for council to take expressions of interest for both sites in June.
Following expressions of interest, council will do further studies and assess them against relevant legislation before making them public.
Cleveland resident Chris Walker said it would have been nice to have had the reports during the public consultation period in February.
But Redland City Council officers said the reports were available for viewing at public consultations and more detailed reports would be done as the project progressed.
"Opportunities to meet with council officers to view the studies were also extended throughout the public consultation period," officers said.
"It was always council’s intention to make the reports publicly available."
Cleveland resident Steve MacDonald said the reports were not available when a panel of planning professionals met to look at alternatives to the Toondah scheme in March.
Reports on Weinam Creek were from Diecke Richards on the structure plan; from Engeny on stormwater and a property market assessment from Jones Lang LaSalle.
