High-rise towers up to 20 storeys at the southern edge of the Perth waterfront redevelopment need to be scaled back to stop them blocking views of the Bell Tower from Kings Park, City of Perth planners say.
Responding to the proposed Metropolitan Region Scheme amendment, the council's planning department has also warned that overshadowing and "wind impacts" on public areas need to be minimised.
The Barnett Government's $440 million waterfront plan has buildings up to 37 storeys along The Esplanade, scaling down to 20 storeys along the river's edge with three to four storeys east of the Bell Tower.
The council report, to go before the planning committee tonight, said heights at the southern river edge should be reduced to a more "human scale", which could mean a tiered development with a lower height at the front of a building rising to more storeys at the rear.
The report said staff opposed moving the heritage-listed Florence Hummerston building, that houses the Grand Palace restaurant, from the Esplanade reserve to the Supreme Court Gardens as it would diminish the building's heritage value and the capacity of the gardens to hold events.
And though the Perth foreshore redevelopment was supported, the report questioned the decision, amid tight project delivery time frames, for separate environmental approvals for land-based and water-based aspects of the plan given they were related.
The Environmental Protection Authority has said key factors were the impact of dredging, river-water quality, stormwater discharge from the Mounts Bay main drain and catchments, inlet hydrodynamics, onshore and offshore acid sulphate soil and contamination and displacement of marine fauna during construction.
However, it found stage-one land works were manageable and covered by existing legislation.A Department of Planning spokeswoman said the stage two EPA referral for inlet works would be supported by management strategies covering construction, dredging, contamination, waterways and water quality monitoring.
