Central Coast Tackles Duplicate Streetscapes in Major Urban Renewal Project

Central Coast Council is quietly dealing with a problem that has quietly undermined urban renewal efforts from Newcastle to Nottingham: duplicate imagery in planning and development documentation that obscures what a neighbourhood actually looks like, and what it's being promised to become.

The issue came into sharper focus this year as the Council — still rebuilding institutional credibility after emerging from state-appointed administration in 2022 — pushed forward with the Gosford City Centre Master Plan. Community reference groups reviewing planning submissions for the Mann Street and Donnison Street precincts flagged that some development applications were recycling render images from entirely different projects, sometimes from interstate proposals, making it difficult to assess how new buildings would actually sit in the streetscape.

A Global Problem With Local Consequences

This isn't unique to the Central Coast. Councils in Birmingham, UK, and in Christchurch, New Zealand — both cities that have undergone significant post-crisis urban rebuilds — have introduced image-verification protocols into their development assessment frameworks in the past three years. Christchurch City Council, rebuilding after the 2011 earthquake sequence, requires applicants to submit geotagged reference photographs alongside render files, with metadata checked against street-address records. Birmingham adopted a similar rule in 2024 after a parliamentary inquiry found that more than 30 per cent of major planning applications in its city centre redevelopment zone contained images sourced from unrelated projects.

The Central Coast has no equivalent formal requirement yet. Under the current NSW Environmental Planning and Assessment Act framework, photomontages and visual impact assessments are required for many developments, but there is no mandated verification step confirming that base images genuinely represent the site. That gap matters more here than in established city centres: the Gosford CBD still has significant vacant lots along Georgiana Terrace and around the old David Jones building site on Mann Street, meaning renders that misrepresent the surrounding context can look plausible on paper while bearing little relation to what future neighbours will actually experience.

The problem is partly one of cost. A professionally prepared, site-accurate 3D photomontage can run between $8,000 and $20,000 for a medium-density development, according to industry pricing guides published by the Australian Institute of Architects. Smaller developers working on the infill sites that dominate Central Coast submissions — often three to six-storey residential blocks in areas like Gosford and Wyong — sometimes reach for stock renders or reuse images from previous projects to cut those costs.

What the Council Is — and Isn't — Doing

Central Coast Council's Development Assessment team has been working since mid-2025 to update its pre-lodgement advice guidelines, with visual documentation forming part of that review. The Council's Planning and Environment directorate confirmed in a publicly available agenda item from the March 2026 ordinary meeting that a revised Development Control Plan chapter covering documentation standards was expected to go on public exhibition in the third quarter of 2026. That window is now open.

Advocacy group Central Coast Community Environment Network, which has offices in Gosford, has been pushing for the DCP update to include explicit image-provenance requirements. The group has pointed to comparable rules already operating under Auckland Council's Unitary Plan, which since 2023 has required applicants to certify that all base photography is site-specific and dated within 12 months of lodgement.

The timing matters. Sydney recorded its hottest June since 1859 this year, and climate resilience planning — including shade, green space, and wind corridor modelling — is increasingly central to what Gosford's renewal is supposed to achieve. Duplicated or misrepresentative imagery makes that kind of assessment harder, not easier. If a render shows a tree-lined plaza that doesn't exist and won't be built, planners and residents are making decisions based on fiction.

Residents reviewing upcoming development applications through the Central Coast Council's DA tracker portal — accessible via the Council's website — should check whether photomontages include a site-photography date and a surveyor's reference point. If neither is present, a formal submission requesting that information is within any objector's rights under the EP&A Act, and Council assessment officers are required to respond. The public exhibition period for the revised DCP chapter is the more significant opportunity: submissions close when the Council sets a formal date, likely before September 30.
