Reviewing planning principles
26Ms Carpenter submitted in passing that steps 2 and 4 of the planning principle regarding assessing the impact of adjacent development on a heritage item (Anglican Church Property Trust v Sydney City Council [2003] NSWLEC 353 at [34]) were relevant to my consideration of this matter.
27As recently observed by the Senior Commissioner in Revelop Projects Pty Ltd v Parramatta City Council [2014] NSWLEC 1167 at [30], the Commissioners of the Court undertook a review of the published list of planning principles in late 2013, in order to determine which planning principles remain relevant in their original form; which, if any, might warrant revision or replacement; and which, if any, were no longer relevant and should be disregarded in the future. The Commissioners have collectively concluded that the heritage planning principle, 'Impact of adjacent development', should no longer be applied.
28The heritage planning principle, 'Impact of adjacent development', does not engage with the long established methodology of defining a heritage curtilage. It approaches the issue only from the perspective of the new development's impact on the heritage item; rather than identifying constraints and opportunities in relation to the assessment of significant values and the setting of the heritage item, based on the definitions of terms in the Burra Charter (The Australia ICOMOS charter for the conservation of places of cultural significance). Relevantly, Article 8 of the Burra Charter states the following:
Conservation requires the maintenance of an appropriate visual setting: e.g., from, scale, colour, texture and materials. No new construction, demolition or modification which would adversely affect the setting should be allowed. Environmental intrusions which adversely affect appreciation or enjoyment of the place should be excluded.
29A Statement of Heritage Impact (SHI) is generally required to assess the impact of a proposal on the setting and context of heritage items in its vicinity (refer to Statements of Heritage Impact publication by Heritage Office and Department of Urban Affairs & Planning 1996, revised 2002, available on the Heritage Council of NSW, Heritage Division of the Office of Environment and Heritage, website). A SHI requires research, analysis and when appropriate, the identification of visual catchments and significant views and vistas, which should inform the proposal's siting, envelope and design development and finally, the SHI must assess what impact the proposal will have on the heritage significance of an item and what measures are proposed to mitigate any impacts. Such an analysis is specific to the context and cannot be appropriately or adequately substituted by a planning principle.
