10. Heritage Resources and Notable Trees Volume One heritage resources that meet the criteria of the policy can be added to the schedule over time. Any such addition must first proceed through the First Schedule process of the RMA. Note that for historic buildings, the area around the building (called the “defined setting”) may also contribute to its heritage significance. Where this is the case, it may be appropriate to also identify the surroundings as part of the heritage resource. [RPS] Policy 10.1.5 – Avoid adverse effects on the historic heritage values of Category I heritage resources. Heritage resources sourced from the New Zealand Heritage List/Rārangi Kōre ro are assigned either a Category I or Category II status. Heritage resources classified as Category I are nationally significant. Any loss or damage of or significant change to a Category I heritage resource would result in a significant and potentially irreversible loss of historic heritage that is important in a national context. For this reason, any adverse effects on the historic heritage values of Category I resources must be avoided. This will see a prohibited activity rule that forbids the loss or destruction of a Category I resource. [RPS, C, D] Policy 10.1.6 – Where modifications are proposed to Category I heritage resources and other heritage resources, the adverse effects of the modifications on the values of the resources should be avoided, remedied or mitigated. Where modification is proposed to a Category I heritage resource, a resource consent will be required to enable assessment of the effects on the values of the specific resource. There may also be circumstances where there is a need for resource consent in respect of other listed heritage resources. Where this is the case, adverse effects on the historic heritage values are able to be avoided, remedied or mitigated after having regard to the matters in Policy 10.1.7. [RPS, C, D] Policy 10.1.7 – When assessing resource consent applications in relation to heritage resources, have regard to: (a) the contribution the heritage resource makes to the local or national identity and sense of place; (b) the effect demolition, removal, alteration or additions will have on the heritage values of the heritage resource; (c) the extent to which the adaptive reuse of a heritage resource enables reasonable and economic use of that resource; (d) the extent to which the work is necessary to enable the continued use of the heritage resource; (e) the extent to which the work is necessary to ensure structural stability, accessibility, fire egress, sufficient earthquake strengthening, and the extent of the impact of the work on the heritage values of the heritage resource; (f) any cumulative effects, especially where the resource is part of a group of similar resources; (g) efforts by the applicant to retain important features of the heritage resource; (h) the extent to which any alteration or addition is in keeping with the original design and materials, or otherwise enhances the heritage value of the resource; (i) the need for ongoing recognition of the significance of sites currently identified by monuments or plaques; (j) options for retaining a heritage resource when its demolition is proposed; and 10 – 4
