What are the critical steps for conducting a preliminary site assessment for a multi-unit residential development in suburban Perth?

A preliminary site assessment for a multi-unit residential development in suburban Perth involves several critical steps. Firstly, verify zoning and planning scheme overlays through the local council and WA Planning Commission to confirm permissible density and building envelopes. Secondly, conduct a desktop review of historical aerial imagery and geological maps to identify potential site constraints like easements, flooding risk, or adverse soil conditions. Thirdly, undertake a physical site walkover to observe immediate surroundings, access points, existing vegetation, services infrastructure, and potential heritage considerations. Finally, assess proximity to public transport, amenities, and community facilities to inform market suitability and development viability, aligning with Perth's suburban growth strategies.
